Introduction

Unless otherwise stated, the income statement analysis compares the period from 5 April 2018 to 30 September 2018 to the corresponding six months of 2017 and balance sheet analysis at 30 September 2018 with comparatives at 4 April 2018.

Underlying profit

Profit before tax shown on a statutory and underlying basis is set out on page 9. Statutory profit before tax of GBP516 million has been adjusted to derive an underlying profit before tax of GBP460 million. The purpose of this measure is to reflect management's view of the Group's underlying performance and to assist with like for like comparisons of performance across periods. Underlying profit is not designed to measure sustainable levels of profitability as that potentially requires exclusion of non-recurring items even though they are closely related to (or even a direct consequence of) the Group's core business activities. The components of underlying profit have changed in the period to more accurately reflect underlying performance. For more information see page 9 of the Financial Review.

Nationwide has developed a financial performance framework based on the fundamental principle of maintaining its capital at a prudent level in excess of regulatory requirements. The framework provides parameters which allow it to calibrate future performance and help ensure that it achieves the right balance between distributing value to members, investing in the business and maintaining financial strength. The most important of these parameters is underlying profit which is a key component of Nationwide's capital. We believe that a level of underlying profit of approximately GBP0.9 billion to GBP1.3 billion per annum over the medium-term would meet the Board's objective for sustainable capital strength. This range will vary from time to time, and whether our profitability falls within or outside this range in any given financial year or period will depend on a number of external and internal factors, including conscious decisions to return value to members or to make investments in the business. It should not be construed as a forecast of the likely level of Nationwide's underlying profit for any financial year or period within a financial year.

Forward looking statements

Certain statements in this document are forward looking with respect to plans, goals and expectations relating to the future financial position, business performance and results of Nationwide.

Joe Garner, Chief Executive, Nationwide Building Society, said:

"Nationwide Building Society exists to serve our members, communities and society. In the last six months, we have continued to grow strongly, our members have continued to benefit from competitive rates, attractive products and leading service, and we have improved our already robust financial position. The strength of our business means we are well placed to invest confidently in the future of the Society, and we have committed to invest an additional GBP1.3 billion over the next five years to transform our technology estate and capabilities. This will take our total investment over the next five years to GBP4.1 billion and will ensure the Society makes the most of the opportunities ahead. We will develop new propositions, further enhance our service, simplify our operations and build new skills for the future.

"This conscious decision to increase our investment is underpinned by the continued strength of our performance over the last six months. We continue to lead our high street peer group for customer satisfaction by a significant margin(1) . We protected savers and rewarded loyal members, delivering GBP330 million in member financial benefit through better rates, fees and incentives than the market average over the half year. The special rate ISA, available exclusively to our loyal members, contributed to a GBP5.1 billion rise in deposits. We continued to support first time buyers, helping a record 40,500 into a home of their own - 1 in 5 of all first time homeowners. And more people are choosing Nationwide for their everyday finances, with almost 400,000 current accounts opened with us so far this year.

"Our success in the personal current account market, where we have grown accounts by 70% in the last five years, has given us the confidence to accelerate our entry into the business banking market. The funding available from the Banking Competition Remedies remains important to us as it will allow us to bring our proposition to market faster and with greater impact. 50,000 members a year ask us to provide business banking, and we believe we can offer a compelling mutual alternative to Britain's currently underserved 5.6 million small businesses. Nationwide is here for the long term and we believe we can make a lasting difference in this market, as we have in the personal current account market, thanks to the combination of leading service and good value we can offer. This is the logical next step in bringing mutuality to more people.

"Our first half profits were lower than last year because we have chosen to increase our investment in the future of our Society. As a mutual, we do not judge our success by profit growth alone, but by how we manage our profits to serve our members' interests. We do that by maintaining the high-quality service and excellent value products our members prize today, while also investing in building new propositions, services, and skills, so we can meet members' future needs."

Mark Rennison, Chief Financial Officer, Nationwide Building Society, said:

"These results show that Nationwide is built to last and continues to provide a secure home for members' money. Trading was strong in the first six months and we have strengthened our CET 1 capital ratio to 31.7%, and UK leverage ratio to 5.0%. This performance gives us the confidence to increase our investment in our future, which will allow us to pursue new opportunities for the benefit of our members. As a building society we do not aim to maximise profit and our decision to increase investment was in the full knowledge that it would impact on our profitability. If we exclude the charge we've recognised for asset write-offs and incremental technology spend, profits are in line with last year and we have held costs flat while servicing rising business volumes. We have continued to make the Society more efficient and are not only on track to deliver our targeted sustainable saves but have also set a more ambitious target for saves by 2023.

"As a mutual we take decisions on rates that are in the long-term interests of our membership, rather than pursuing short-term gain. We anticipate this, and the competitive market, will lead to further pressure on margins in the second half of the year. Despite the uncertain political and economic environment, our financial strength gives us confidence that we can continue to be there for our members in the months and years ahead in the same way that we have always been."

Notes:

i. Underlying profit represents management's view of underlying performance. In order to provide a more meaningful presentation of performance the following items are excluded from statutory profit to arrive at underlying profit:

   a.      FSCS costs arising from institutional failures 
   b.     Gains from derivatives and hedge accounting. 

Comparatives have been restated to reflect changes to the definition of underlying profit. Further information can be found in the Financial review.

ii. The calculation of market share for mortgage lending and deposit balances has been refined to better reflect the position at the reporting date, with comparatives restated accordingly. Market data is available at calendar month ends and therefore market share for the half year is for the period 1 April to 30 September.

   iii.    Member deposits include current account credit balances. 

iv. Balances as at 5 April 2018 reflect the impact of applying IFRS 9: Financial Instruments. Further information can be found in note 2 to the Financial statements.

v. Charged off balances relate to accounts which are closed to future transactions and are held on the balance sheet for an extended period (up to 36 months, depending on the product) whilst recovery procedures take place.

vi. The Common Equity Tier 1 (CET1) ratio has been calculated under CRD IV on an end point basis. For 30 September 2018 and 5 April 2018, IFRS 9 transitional arrangements have been applied.

vii. The UK leverage ratio is shown on the basis of measurement announced by the Prudential Regulation Authority (PRA) and excludes eligible central bank reserves from the leverage exposure measure. For 30 September 2018 and 5 April 2018, IFRS 9 transitional arrangements have been applied.

viii. The Capital Requirements Regulation (CRR) leverage ratio is calculated using the CRR definition of Tier 1 for the capital amount and the Delegated Act definition of the exposure measure and is reported on an end point basis. For 30 September 2018 and 5 April 2018, IFRS 9 transitional arrangements have been applied.

ix. The wholesale funding ratio includes all balance sheet sources of funding (including securitisations).

Chief Executive's review

Our purpose, building society, nationwide, describes our aspirations to grow the Society for the benefit of our members, customers, colleagues, and society more generally. It is underpinned by five strategic cornerstones that describe what we aim to do and how we will do it.

Built to last - strong finances and a low risk profile

We are financially stronger than ever, with our UK leverage ratio at 5.0%, and our CET1 capital ratio at 31.7%. Our loan book remains low risk, with the average loan to value ratio for new lending stable at 71%.

Our financial and trading strength has put us in a very strong position to increase investment in technology by GBP1.3 billion, taking our total planned investment in the Society to GBP4.1 billion in the coming five years. This investment will impact profitability over the medium term. Underlying profit for H1 2018/19 of GBP460 million (H1 2017/18: GBP589 million) is in line with our expectations and includes a charge of GBP135 million associated with this investment. Excluding this charge, profits are in line with last year and we delivered flat costs of GBP965 million (H1 2017/18: GBP966 million).

As we've said in the past, our aim is not to maximise profits, but manage our profits in our members' interests - through a balance of maintaining our financial strength, rewarding members, and investing to meet their future needs. We have consciously continued to protect savers and reward loyal members in the first half of the year which has reduced margins, in line with expectations. We expect this to continue into the second half of the year as we balance the needs of our members in a competitive market.

Building thriving membership - attracting more people to mutuality

We continue to be true to our founding purpose of helping people into homes of their own: record numbers of first time buyers chose a mortgage with Nationwide, benefiting from a package that includes GBP500 cashback and a free valuation. We're testing a retirement interest only mortgage with our members alongside our existing equity release mortgage for people in later life. We've made it quicker and easier for members to remortgage online and also enhanced our buy-to-let proposition. As a result, our gross prime mortgage lending was broadly in line with last year at GBP15.2 billion (H1 2017/18: GBP15.0 billion). We increased gross buy-to-let lending to GBP2.1 billion (H1 2017/18: GBP1.7 billion).

We continued to reward members by launching good value products including our Loyalty ISA and a new children's account, with rates of up to 3.5%. Our commitment to supporting savers helped us increase member deposits by GBP5.1 billion (H1 2017/18: GBP1.8 billion) and meant that, over the past six months, we attracted almost 18% of the growth in deposits in the UK (H1 2017/18: 4.5%). We also rewarded members with GBP250 million additional deposit interest (H1 2017/18: GBP180 million), with average deposit rates more than 50% higher than the market average(1) .

More people chose to open a current account with us in the first half of the year than with any other high street brand(2) , and we attracted more than one in five current account switchers(3) . Our stock of all current accounts continues to grow and now stands at 7.6 million and we've grown our share of main standard and packaged current accounts from 6% five years ago to around 8% today.

Building legendary service - number 1 for service and trust

The quality of our service is a fundamental part of our relationship with our members. We believe it's a major factor in attracting new members and keeping existing ones, which is why we work hard to give our members outstanding service whenever they engage with us. We have been number 1 for customer satisfaction among our high street peer group for more than six years(4) and are recognised as the most trusted financial brand in the UK(5) . We also improved our performance in the Institute of Customer Service's UK Customer Satisfaction Index from joint seventh to joint fifth between January and July 2018.

We know that members' expectations of service are constantly rising, and we must rise to meet them. This was an important factor in our decision to invest in our technology for the future. However, we know our members value the personal service they get in branches, which is why our GBP4.1 billion investment also includes GBP350 million to enhance our branch network.

Chief Executive's review (continued)

Building PRIDE - recognising and investing in our people

Everything we achieve as a Society is down to the hard work and commitment of our colleagues. We place great importance on the culture of the Society and the behaviours and values that underpin it; Nationwide believes fundamentally in inclusion and was proud to be one of the first businesses to sign the Race at Work Charter.

As part of our technology investment we will be creating up to 1,000 new roles.

Building a national treasure - reflecting the social purpose that lies at the heart of our mutuality

We continue to invest in our communities through our social investment programme. We've moved from pilot to implementation in our GBP20 million, five-year community funding programme, which centres on helping people into a place fit to call home, with 34 projects chosen by our members receiving a total of almost GBP1 million in the last six months. In Swindon, we continue to work in partnership with the borough council to help to develop a community of up to 250 homes. We are committed to help raise standards in the private rented sector, confirming our support for indefinite tenancies in the government's consultation. In October, we launched our Open Banking for Good challenge to find solutions to financial capability issues using the functionality of Open Banking.

Outlook

Looking ahead, the economic outlook remains mixed. While the UK economy has continued to grow, with employment at or close to historic highs and wages rising in real terms, obvious challenges remain. Most notably uncertainties, including those surrounding Brexit, appear to be holding back investment and dampening activity in the housing market. Despite this, we expect the economy to grow in the quarters ahead - more slowly at first, and at a faster pace as the level of uncertainty eases. We expect the housing market to mirror trends in the wider economy. Against this backdrop, the Society is strong and secure, with a growing membership and business, and is well placed to support our members with the products and services they need to manage their financial lives.

In summary

 
 As the world's largest building society, Nationwide's          Underlying 
  aim is to strike a balance between the value we return         profit: 
  to members through good value products and services,           GBP460m 
  the profits we retain to fund future growth and sustain        (H1 2017/18: 
  strong capital ratios and the level of investment that         GBP589m) 
  we make for the benefit of members. We therefore do            Statutory 
  not aim to maximise profit.                                    profit: 
  Decisions to distribute value to members, invest in            GBP516m 
  the Society and retain profits are guided by our Financial     (H1 2017/18: 
  Performance Framework. We remain committed to this             GBP628m) 
  framework and expect to continue our recent track record       UK leverage 
  of improving capital ratios, excluding the impact of           ratio: 5.0% 
  any capital calls we choose to make and proposed regulatory    (4 April 
  changes.                                                       2018: 4.9%) 
  Trading performance for the period has been robust 
  with one of the strongest ever gross lending performances 
  in the first half of the financial year at GBP17.3 
  billion (H1 2017/18: GBP16.7 billion), and a growth 
  in member deposits of GBP5.1 billion (H1 2017/18: GBP1.8 
  billion), as we continued to offer our members competitive 
  products. 
 

Underlying profit for the period has reduced by 22% to GBP460 million (H1 2017/18: GBP589 million). This is principally due to a charge of GBP135 million driven by asset write-offs and additional investment in technology, in line with our recent technology strategy announcement.

We continue to make good progress on our efficiency programme and are on track to deliver GBP100 million of sustainable saves this year. To date we have delivered over half our previous target of GBP300 million of sustainable saves by 2022 and have now revised our target to GBP500 million to be delivered by 2023.

Nationwide's UK leverage ratio is 5.0%, well in excess of current and anticipated regulatory requirements.

On 5 April 2018 we implemented IFRS 9: Financial Instruments. The total impact on members' interests and equity, net of deferred tax, was a reduction of GBP162 million. There has been no restatement of comparatives following adoption of IFRS 9. Where useful for the interpretation of balances or movements, we have highlighted the impact on the Group's balance sheet and members' interests and equity at 5 April 2018.

Notes:

i. Under IFRS 9, the recognition and measurement of expected credit losses differs from under IAS 39. As prior period amounts have not been restated, impairment losses on loans and advances in the comparative period remain in accordance with IAS 39 and are therefore not directly comparable with impairment losses recorded for the current period.

ii. Underlying profit represents management's view of underlying performance. In order to provide a more meaningful presentation of performance the following items are excluded from statutory profit to arrive at underlying profit:

-- FSCS costs arising from institutional failures, which are included within provisions for liabilities and charges.

-- Gains from derivatives and hedge accounting, which are presented separately within total income.

iii. Although we only use derivatives to hedge market risks, income statement volatility can still arise due to hedge accounting ineffectiveness or because hedge accounting is either not applied or is not achievable. This volatility is largely attributable to accounting rules which do not fully reflect the economic reality of the hedging strategy.

The components of underlying profit have been changed in the period to reflect more appropriately ongoing business performance. Underlying profit now includes the bank levy and FSCS management expenses, which were previously excluded. The impact of this change at the half year is not significant, with H1 2017/18 comparatives restated to increase the previously reported underlying profit by GBP1 million to GBP589 million. The impact of this change for the full financial year will be more significant, as the bank levy expense (GBP45 million in 2017/18), which is incurred in the second half of the year, will be reported within underlying profit.

Total income and margin

Net interest margin for the period was 1.27% compared to 1.34% for H1 2017/18 and 1.31% for our last full financial year. Gradual pressure on margin continues to be driven by intense competition in retail lending markets generally, and particularly in relation to both prime and buy to let mortgages. Attractive new business pricing, combined with a base rate change in the period, has encouraged product switching and refinancing, with GBP10.5 billion of prime mortgage customer balances switching to a new Nationwide product in the period (H1 2017/18: GBP8.7 billion) and legacy base mortgage rate (BMR) balances continuing to run off. BMR balances at 30 September 2018 were GBP20.7 billion (30 September 2017: GBP26.3 billion; 4 April 2018: GBP22.7 billion).

The decline in mortgage margins has been only partially offset by a reduction in our cost of funding as we have continued to manage savings pricing in line with our commitment to provide good long-term value for members. During the period depositors have continued to earn average rates more than 50% higher than market average(1) .

Net other income has decreased to GBP95 million (H1 2017/18: GBP125 million), predominantly due to the prior period including a one-off gain of GBP26 million from the sale of our investment in VocaLink.

Financial review (continued)

Member financial benefit

We provide value to members through the highly competitive mortgage, savings and banking products that we offer as a direct result of being a member-owned business. The calculation method used to quantify member financial benefit is described in full in the Financial review section of the Annual Report and Accounts 2018. In summary, we quantify the financial benefit of being a member by comparing the following to industry benchmarks:

   --      interest rates on mortgages, unsecured lending and retail deposits; and 
   --      the fees we charge and incentives we provide to members. 

During the period we have provided members with a financial benefit of GBP330 million (H1 2017/18: GBP245 million), including GBP250 million (H1 2017/18: GBP180 million) relating to higher interest paid to depositors. In addition, since making personal loans a member only proposition, we have increased the level of member financial benefit by offering our lowest ever rates. This reflects our ongoing commitment to delivering long-term value to members despite strong levels of competition in our core markets.

Administrative expenses

Administrative expenses include the impact of incremental expenditure and write-offs associated with our recent Technology Strategy announcement. The strategy incorporates GBP1.3 billion of incremental expenditure to be incurred over 5 years targeting the simplification of our technology estate alongside investment in digital service and data capabilities. During the period we have recognised a charge of GBP135 million comprising direct expenditure of GBP31 million in connection with the programme and asset write-offs and impairments of GBP104 million.

Excluding this charge, the remainder of our cost base at GBP965 million was flat by comparison with GBP966 million reported in H1 2017/18. Our continued focus on efficiency has allowed us to absorb inflation, volume growth and the impact of prior year investment. We are on track to deliver GBP100 million of in year sustainable saves and have now delivered over half of our original target of GBP300 million sustainable saves by 2022; we have therefore revised our target to GBP500 million sustainable saves by 2023.

Following a recent High Court case concerning industry-wide inequalities in the calculation of Guaranteed Minimum Pensions (GMP), a one-off charge is expected to be recognised in the second half of the year in respect of past service costs. The exact impact is currently being assessed but is not expected to be material. Further details are included in note 24.

Impairment losses on loans and advances to customers

Impairment losses have decreased by GBP14 million to GBP45 million (H1 2017/18: GBP59 million) largely due to the prior period including additional retail impairments from updates to provision assumptions to reflect economic conditions.

Note:

Under IFRS 9, the recognition and measurement of expected credit losses differs from under IAS 39. As prior period amounts have not been restated, impairment losses in the comparative period are therefore not necessarily comparable to impairment losses recorded for the current period.

Provisions for liabilities and charges

We hold provisions for customer redress to cover the costs of remediation and redress in relation to past sales of financial products and post sales administration, including compliance with consumer credit legislation and other regulatory requirements. During the period there has been a release of GBP15 million (H1 2017/18: GBP25 million charge), reflecting latest estimates of the liabilities. More information is included in note 17.

Financial review (continued)

Taxation

The tax charge for the period of GBP129 million (H1 2017/18: GBP157 million) represents an effective tax rate of 25.1% (H1 2017/18: 25.0%) which is higher than the statutory UK corporation tax rate of 19% (H1 2017/18: 19%). The effective tax rate is higher due to the banking surcharge, equivalent to GBP25 million (H1 2017/18: GBP33 million), and the effect of non-taxable customer redress releases and disallowable expenses of GBP1 million credit and GBP7 million charge respectively (H1 2017/18: GBP1 million charge and GBP4 million charge). Further information is provided in note 9.

Balance sheet

 
 Total assets have increased by GBP9.2 billion during the period     Liquidity coverage ratio: 131.9% 
  to GBP238.3 billion (4 April 2018: GBP229.1 billion) with GBP3.6    (4 April 2018: 130.3%) 
  billion of net mortgage lending (H1 2017/18: GBP3.9 billion). 
  Mortgage lending has been funded by a strong growth in retail 
  deposit balances, with member deposits growing by GBP5.1 billion 
  to GBP153.1 billion (4 April 2018: GBP148.0 billion) and our 
  market share of UK deposits increasing to 10.1% (31 March 2018: 
  10.0%). Of the growth in member deposits, GBP1.9 billion is 
  attributable to current account balances, with our share of 
  current account switchers increasing to 21.5% during the period 
  (H1 2017/18: 20.2%).

Notes:

   i.     Balances as at 5 April 2018 reflect the impact of applying IFRS 9: Financial Instruments. 

ii. Residential mortgages include prime and specialist loans, with the specialist portfolio primarily comprising buy to let lending.

iii. Charged off balances relate to accounts which are closed to future transactions and are held on the balance sheet for an extended period (up to 36 months, depending on the product) whilst recovery procedures take place.

Residential mortgages

Total gross mortgage lending during the period has increased to GBP17.3 billion (H1 2017/18: GBP16.7 billion), of which gross prime lending increased to GBP15.2 billion (H1 2017/18: GBP15.0 billion) and gross specialist lending increased to GBP2.1 billion (H1 2017/18: GBP1.7 billion). This represents one of our strongest gross lending performances in the first half of a financial year, reflecting the competitively priced products and good long-term value that we continue to offer members.

Net mortgage lending was GBP3.6 billion (H1 2017/18: GBP3.9 billion) largely driven by a rise in redemptions due to sustained market competition.

Arrears performance improved marginally during the period, with cases more than three months in arrears improving to 0.42% of the total portfolio (5 April 2018: 0.43%). Impairment provisions have remained largely unchanged at GBP234 million (5 April 2018: GBP235 million).

Financial review (continued)

Commercial and other lending

During the period commercial and other lending balances decreased by GBP0.3 billion to GBP10.4 billion (5 April 2018: GBP10.7 billion). Given deleveraging activity in previous financial years, the overall portfolio is increasingly weighted towards registered social landlords, with balances of GBP6.5 billion (5 April 2018: GBP6.8 billion). Commercial real estate balances decreased by GBP0.2 billion during the period to GBP1.6 billion (5 April 2018: GBP1.8 billion) as we actively reduced this portfolio. Impairment provisions have remained stable at GBP30 million (5 April 2018: GBP29 million).

Consumer banking

The asset quality of the portfolio remains strong. Impairment provisions have increased to GBP371 million (5 April 2018: GBP365 million), as a result of book growth.

Other financial assets

Other financial assets total GBP40.4 billion (5 April 2018: GBP34.8 billion), primarily comprising liquidity and investment assets held by our Treasury function of GBP36.0 billion (5 April 2018: GBP30.8 billion) and derivatives with positive fair values of GBP4.5 billion (5 April 2018: GBP4.1 billion). Derivatives relate primarily to interest rate and foreign exchange contracts which economically hedge financial risks inherent in core lending and funding activities.

The Liquidity Coverage Ratio has increased to 131.9% (4 April 2018: 130.3%) largely due to strong member deposit inflows increasing the liquid asset buffer.

Note:

i. Balances as at 5 April 2018 reflect the impact of applying IFRS 9: Financial Instruments.

Member deposits

Member deposits have increased by GBP5.1 billion to GBP153.1 billion (4 April 2018: GBP148.0 billion) as we continue to offer competitive savings and current account propositions which provide good long-term value. We have continued to attract inflows from both new and existing members through the introduction of successful products such as our Single Access ISA and Loyalty ISA. Nationwide's share of the balance growth in the UK deposit market for the period is 17.9% (H1 2017/18: 4.5%).

Of this balance growth, GBP1.8 billion relates to net inflows into current account products, with in-credit balances on those accounts amounting to GBP21.6 billion (4 April 2018: GBP19.8 billion). During the period our share of current account switchers increased to 21.5% (H1 2017/18: 20.2%).

Debt securities in issue and other financial liabilities

Debt securities in issue of GBP35.3 billion (5 April 2018: GBP34.1 billion) are used to raise funding in wholesale markets to finance core activities. Other financial liabilities have increased by GBP2.7 billion to GBP35.9 billion (5 April 2018: GBP33.2 billion) as a result of capital funding issuances and liquidity financing transactions. Further details are included in the Liquidity and funding risk section of the Business and risk report.

Members' interests and equity

The more significant movements in the period are retained profit after tax, net remeasurement of pension obligations and the impact of adopting IFRS 9: Financial Instruments at 5 April 2018. Further details on the impact of transition to IFRS 9 are included in note 2.

Capital structure

Capital resources have continued to strengthen during the period with the CET1 ratio increasing to 31.7% (4 April 2018: 30.5%) and the UK leverage ratio to 5.0% (4 April 2018: 4.9%). Both are comfortably in excess of minimum regulatory capital requirements and Nationwide's strategic target of maintaining a UK leverage ratio of greater than 4.5%.

Notes:

i. Data in the table is reported under CRD IV on an end point basis with IFRS 9 transitional arrangements applied.

ii. The UK leverage ratio is shown on the basis of measurement announced by the Prudential Regulation Authority (PRA) and excludes eligible central bank reserves from the leverage exposure measure.

iii. The Capital Requirements Regulation (CRR) leverage ratio is calculated using the CRR definition of Tier 1 for the capital amount and the Delegated Act definition of the exposure measure and is reported on an end point basis. Further details are provided in the Solvency risk section of the Business and risk report.

iv. Figures have been adjusted to reflect the impact of applying IFRS 9 from 5 April 2018. Further information is provided in the Report on Transition to IFRS 9: Financial Instruments, which can be found at nationwide.co.uk.

CET1 capital resources have increased by GBP0.5 billion since 5 April 2018, primarily due to profit after tax for the period of GBP387 million and net remeasurement of pension obligations of GBP155 million. Risk weighted assets (RWAs) have remained relatively stable with a reduction in commercial exposures being offset by increases for counterparty credit risk and other exposures. These movements have resulted in the CET1 ratio increasing to 31.7%.

Lending growth has been more than offset by profits for the period, with Tier 1 resources growing more quickly than leverage exposure. This resulted in the UK leverage ratio increasing to 5.0%. CRR leverage ratio has remained stable at 4.6%.

Introduction

This report provides information on developments during the period in relation to Nationwide's business, the risks it is exposed to and how it manages those risks. This information supports, and should be read in conjunction with, the material found in the Business and Risk Report in the Annual Report and Accounts 2018. Where there has been no change to the approach to managing risks, or there has been no material change to the relevant risk environment from that disclosed at year end, this information has not been repeated in the 2018/19 Interim Results.

Principal risks

Effective risk management is fundamental to the success of Nationwide's business and has an important part to play in delivering the Society's purpose of building society, nationwide, by making sure it is safe and secure for the future. Whilst it is accepted that all business activities involve some degree of risk, Nationwide seeks to protect its members by managing appropriately the risks that arise from its activities. The principal types of risk inherent within the business remain unchanged from those set out in the Business and risk report in the Annual Report and Accounts 2018, namely:

 
                                          *    Model risk 
        *    Credit risk 
 
        *    Liquidity and funding risk          *    Conduct and compliance risk 
                                          *    Market risk 
        *    Solvency risk 
                                          *    Business risk 
        *    Pension risk 
 
        *    Operational risk 
 

Information on key developments and updated quantitative disclosures for the principal risks above are included within this report except for model risk, business risk and market risk where there have been no significant developments during the period.

Top and emerging risks

The top and emerging risks to the delivery of Nationwide's strategy are identified through the processes outlined in the Business and risk report section of the Annual Report and Accounts 2018. These top and emerging risks to Nationwide's strategy are summarised in the table below, along with details of key movements and developments during the period.

Credit risk - Overview

Credit risk is the risk of loss as a result of a member, customer or counterparty failing to meet their financial obligations. Credit risk also encompasses concentration risk and refinance risk.

Nationwide manages credit risk for each of the following portfolios:

 
Portfolio         Definition 
Residential       Loans secured on residential property 
 mortgages 
                  ------------------------------------------------------------ 
Consumer banking  Unsecured lending including current account overdrafts, 
                   personal loans and credit cards 
                  ------------------------------------------------------------ 
Commercial and    Loans to registered social landlords, loans made under 
 other lending     the Private Finance Initiative and commercial real 
                   estate lending. Also includes deferred consideration 
                   and collateral balances to support repurchase transactions. 
                  ------------------------------------------------------------ 
Treasury          Treasury liquidity, derivatives and discretionary 
                   portfolios 
                  ------------------------------------------------------------ 
 

With effect from 5 April 2018 Nationwide has adopted IFRS 9: Financial Instruments which replaces IAS 39 Financial Instruments: Recognition and Measurement. Under IFRS 9, impairment provisions on financial assets are calculated on an expected credit loss (ECL) basis for assets held at amortised cost and fair value through other comprehensive income (FVOCI). ECL impairment provisions are based on an assessment of the probability of default, exposure at default and loss given default, discounted to give a net present value. The Credit risk section of this report summarises for portfolios:

   --      the maximum exposure to credit risk; 
   --      the stage distribution of loans and provisions (explained on page 18); 
   --      credit quality; 

-- other risk factors and concentrations, including loan to values, regional exposures, arrears and forbearance.

Further information on the move to IFRS 9 is provided in our Report on Transition to IFRS 9: Financial Instruments, which can be found on nationwide.co.uk

In the consolidated interim financial statements there has been no restatement of comparative information for the year ended 4 April 2018, which is reported on an IAS 39 basis. However, to support the understanding of the current year IFRS 9 disclosures, certain comparative balances within the Credit risk section of this Business and risk report are shown as at 5 April 2018 (the effective date of the adoption of IFRS 9). These 5 April 2018 comparatives include financial asset balance sheet carrying values that have been changed by IFRS 9, and the stage distribution of gross lending and ECL provisions.

The stage distribution of gross lending and provisions for loans and advances to customers is presented for assets held at amortised cost, and certain tables below therefore exclude loans and advances to customers classified as fair value through profit or loss (FVTPL).

The table below shows the classification of assets on the Group's balance sheet following the adoption of IFRS 9.

Notes:

i. In addition to the amounts shown above, Nationwide has, as part of its retail operations, revocable commitments of GBP9,700 million (5 April 2018: GBP9,517 million) in respect of credit card and overdraft facilities. These commitments represent agreements to lend in the future, subject to certain considerations. Such commitments are cancellable by Nationwide, subject to notice requirements, and given their nature are not expected to be drawn down to the full level of exposure.

ii. The fair value adjustment for portfolio hedged risk and the fair value adjustment for micro hedged risk (which relates to the commercial lending portfolio) represent hedge accounting adjustments. They are indirectly exposed to credit risk through the relationship with the underlying loans covered by Nationwide's hedging programmes.

   iii.    FVTPL residential mortgages includes equity release loans. 

iv. Comparative values for commitments have been restated to reclassify the commitment value in respect of one counterparty from loans and advances to banks to commercial and other lending.

Credit risk - Overview (continued)

Commitments

Irrevocable undrawn commitments to lend are within the scope of IFRS 9 provision requirements. The commitments in the table above consist of overpayment reserves and separately identifiable irrevocable commitments for the pipeline of residential mortgages, personal loans, commercial loans and investment securities. These commitments are not recognised on the balance sheet, and the total associated provision of GBP0.3 million (5 April 2018: GBP0.6 million) is included within provisions for liabilities and charges.

Revocable commitments relating to overdrafts and credit cards are included in ECL based provisions, with the allowance for future drawdowns made as part of the exposure at default element of the ECL calculation.

As impairment provisions are calculated on a different basis under IFRS 9 from IAS 39, the losses shown above are not directly comparable.

Stage distribution

Impairment provisions are calculated using a three stage approach depending on changes in credit risk since original recognition of the assets:

-- an asset that is not credit impaired on initial recognition is classified in stage 1, with a provision equal to a 12 month ECL (losses arising on default events expected to occur within 12 months);

-- where a loan's credit risk increases significantly, it will be moved to stage 2. The provision recognised will be equal to the loan's lifetime ECL (losses on default events expected to occur at any point during the life of the asset); and

-- if a loan meets the definition of credit impaired, it will be moved to stage 3 with a provision equal to its lifetime ECL.

For loans and advances to customers held at amortised cost, the stage distribution of portfolios, including provision coverage ratios, is shown in the individual credit risk sections for residential mortgages, consumer banking and commercial and other lending. The provision coverage ratio is calculated by dividing the provisions by the gross balances for each main lending portfolio. Loans remain on the balance sheet, net of associated provisions, until they are deemed no longer recoverable, when such loans are written off. The definition, assumptions and timing for write-off of loans have not changed with the adoption of IFRS 9.

Other assets in scope for impairment provisions are shown below:

The credit quality of loans and advances to banks and investment securities continues to be low risk and stable. All items within the table above are classified as stage one, except for GBP12 million of FVOCI investment securities in stage two, with no assets in stage three.

For financial assets classified as FVTPL, no provisions are calculated as credit risk is reflected in the carrying value of the asset; no additional provision information is therefore disclosed in respect of these assets.

Credit risk - Residential mortgages

Lending and new business

Summary

Nationwide's residential mortgages include both prime and specialist loans. Prime residential mortgages are mainly Nationwide-branded advances made through the branch network and intermediary channels. Specialist lending consists principally of buy to let mortgages originated under The Mortgage Works (UK) plc (TMW) brand. Total balances across these portfolios have grown by 2.1% during the period to GBP181 billion (4 April 2018: GBP177 billion) and credit performance has remained stable.

i. Other includes self-certified, near prime and sub prime lending, all of which were discontinued in 2009.

ii. As a result of their contractual cash flow characteristics, certain residential mortgages (including equity release loans) were reclassified from amortised cost to FVTPL on transition to IFRS 9 on 5 April 2018, and remeasured at fair value as disclosed in the above table.

Nationwide is committed to helping people become homeowners and continues to actively support first time buyers. New lending in the prime portfolio has seen the residential mortgage exposure grow from GBP144 billion to GBP148 billion over the period, with new lending to first time buyers comprising 38% (30 September 2017: 37%) of all new lending. Nationwide continues to operate with a commitment to responsible lending and a focus on championing good conduct and fair outcomes.

The following table shows residential mortgage lending balances carried at amortised cost, the stage allocation of the loans, impairment provisions and the resulting provision coverage ratios:

Notes:

   i.       Days past due, a measure of arrears status. 

ii. Purchased or originated credit impaired (POCI) loans. The gross balance for POCI is net of the lifetime ECL of GBP6 million (GBP7 million at 5 April 2018).

At 30 September 2018, 89% (5 April 2018: 88%) of the residential mortgage portfolio is in stage 1. Of the GBP18,785 million (5 April 2018: GBP19,072 million) stage 2 balances, 2.6% (5 April 2018: 2.4%) are in arrears by 30 days or more. The majority are in stage 2 due to non-arrears factors, including interest only loans where it anticipated that a borrower may not have a means of capital repayment or the ability to refinance the loan at maturity. The movements in stage 2 balances and associated provisions for prime and specialist loans since 5 April 2018 are a result of refinements to models and staging criteria, with stable underlying credit performance.

Stage 3 loans in the residential mortgage portfolio (excluding POCI), equate to 1% (5 April 2018: 1%) of the total residential mortgage exposure. Of the total value of residential mortgage balances in stage 3 at 30 September 2018 (excluding POCI), GBP678 million (5 April 2018: GBP686 million) is more than 90 days past due.

The stage 3 POCI loans were recognised on the balance sheet when the Derbyshire Building Society was acquired in December 2008. These mainly interest-only residential loans were 90 days or more in arrears when they were acquired and so have been classified as credit impaired on acquisition.

Total provisions and provision coverage across the residential mortgage portfolio have remained stable, with movements in prime and specialist loans since 5 April 2018 resulting from model refinements and updates to the probabilities applied to economic scenarios in modelling ECLs.

Credit quality

Residential mortgage lending continues to have a low risk profile as demonstrated by a low level of arrears compared to the industry average. The residential mortgages portfolio comprises many relatively small loans which are broadly homogenous, have low volatility of credit risk outcomes and are geographically diversified.

Nationwide adopts robust credit management policies and processes designed to recognise and manage the risks arising from the portfolio.

The table below shows the loan balances and provisions for amortised cost residential mortgages, by probability of default (PD) range. The PD distributions shown are based on 12 month PD at the reporting date.

The provisions allocated to the lowest PD ranges primarily reflect provisions recognised for interest only loans where it is anticipated that a borrower may not have a means of capital repayment or the ability to refinance the loan at maturity.

Over the period, the quality of the residential mortgage portfolios has remained strong, benefiting from low interest rates, with 98% (5 April 2018: 98%) of the portfolio having a PD of less than 2.5%.

In addition to the amortised cost loans shown above, there are GBP189 million (5 April 2018: GBP189 million) residential mortgages classified at FVTPL which have an average 12 month PD of 2.17% (5 April 2018: 2.07%).

LTV and credit risk concentration

Loan to value (LTV) is calculated by weighting the borrower level LTV by the individual loan balance to arrive at an average LTV. This approach is considered to most appropriately reflect the exposure at risk.

Over the period, the geographical distribution across the UK has remained stable, with the highest concentration continuing to be in Greater London, at 34% of the total.

The proportion of loan balances with LTV greater than 80% has remained stable at 11% across the stage 1 and 2 balances, whilst the proportion of stage 3 balances with LTV greater than 80% has reduced slightly over the period, from 13% to 11%.

The value of partially collateralised loans has reduced to GBP235 million (5 April 2018: GBP260 million).

In addition to the amortised cost balances in the table above, there are GBP189 million (5 April 2018: GBP189 million) FVTPL residential mortgages which have an average LTV of 39.8% (5 April 2018: 39.8%). The geographical distribution is similar to the amortised cost balances, with the largest proportion in Greater London, at 33% (5 April 2018: 33%).

Note: The methodology for calculating mortgage arrears is based on the UK Finance (UKF) definition of arrears, where months in arrears is determined by dividing the arrears balance outstanding by the latest contractual payment.

The proportion of loans in arrears across prime and specialist lending remains low, reflecting the favourable economic conditions and low interest rate environment, supported by robust credit management policies and processes designed to recognise and manage the risks arising, or likely to arise, from the portfolio.

Whilst there are no signs of deterioration in the portfolio, with the immediate outlook for the UK being less certain and the buy to let market facing increased costs and potentially less investor demand, the expectation is for a gradual rise in arrears from these low levels.

Total balances subject to arrears represent 1.6% (4 April 2018: 1.5%) of the total residential mortgage lending.

Interest only mortgages

Interest only balances for prime residential mortgages relate primarily to historical balances which were originally advanced as interest only mortgages or where a change in terms to an interest only basis was agreed. Maturities on interest only mortgages are managed closely, engaging regularly with borrowers to ensure the loan is redeemed or to agree a strategy for repayment.

Credit risk - Residential mortgages (continued)

The majority of the specialist portfolio comprises buy to let loans, of which 89% are advanced on an interest only basis as at 30 September 2018.

Notes:

i. Balances subject to forbearance with agreed term extensions are presented based on the latest agreed contractual term.

Interest only loans that are 'term expired (still open)' are not considered to be past due where contractual interest payments continue to be met, pending renegotiation of the facility. Under IFRS 9 these are now treated as impaired and form part of the stage 3 balance from three months after the maturity date. Previously, term expired (still open) loans were not categorised as impaired unless in litigation or more than 3 months in arrears on the contractual interest payments.

Forbearance

Nationwide is committed to supporting borrowers facing financial difficulty by working with them to find a solution through proactive arrears management and forbearance. The Annual Report and Accounts 2018 sets out further details of concession events included within forbearance.

The table below provides details of residential mortgages held at amortised cost subject to forbearance, which are all assessed as in either stage 2 or stage 3:

Notes:

i. Where more than one concession event has occurred, balances are reported under the latest event.

ii. Includes interest only mortgages where a customer is unable to renegotiate the facility within six months of maturity and no legal enforcement is pursued. Should a concession event such as a term extension occur within the six-month period, this will also be classed as forbearance.

In addition to the amortised cost balances, there are GBP189 million FVTPL balances (5 April 2018: GBP189 million), of which GBP18 million (5 April 2018: GBP19 million) are forborne, with the majority within the past term interest only category.

Consistent with the European Banking Authority reporting definitions, loans that meet the regulatory forbearance exit criteria are not reported as forborne.

Credit risk - Consumer banking

Summary

The consumer banking portfolio comprises balances on unsecured retail banking products, specifically overdrawn current accounts, personal loans and credit cards. Total balances across these portfolios have grown by 5.1% during the period to GBP4,316 million (4 April 2018: GBP4,107 million), and the performance has remained stable.

We continue to monitor carefully the composition and performance of the unsecured portfolios, in light of the growth in consumer credit balances observed across the industry, and are aware of the pressure that some members will be under, with increasing levels of household debt. We continue to operate with a commitment to responsible lending and a focus on championing good conduct and fair outcomes.

Credit risk - Consumer banking (continued)

As at 30 September 2018, 79% (5 April 2018: 79%) of the consumer banking portfolio remains in stage 1. Of the GBP642 million stage 2 balances, GBP16 million (5 April 2018: GBP16 million) is in arrears by 30 days or more. The remainder is in stage 2 due to non-arrears factors such as increased probability of default since origination. Overdrawn current account stage 2 balances represent 40% (5 April 2018: 34%) of the total overdrawn balances, but relate to 8% of the total number of current accounts (5 April 2018: 8%).

The increase in stage 2 personal loan balances since 5 April 2018 is largely attributable to a refinement of PD calculations leading to some loans with relatively low PDs being transferred to stage 2, with limited provision impact. The credit quality of the portfolio remains stable.

Consumer banking stage 3 gross balances and provisions include charged off balances. These are in relation to accounts which are closed to future transactions and are held on the balance sheet for an extended period (up to 36 months) whilst recovery activities take place. Excluding these charged off balances and related provisions, the provision coverage ratio is 4.5% (5 April 2018: 4.8%).

Credit quality

Nationwide adopts robust credit management policies and processes designed to recognise and manage the risks arising from the portfolio.

The following table shows gross balances and provisions for consumer banking balances held at amortised cost, by PD range. The PD distributions shown are based on 12 month probability of default at the reporting date.

The credit quality of the consumer banking portfolios has remained strong, benefiting from low interest rates, with 90% of the portfolio (5 April 2018: 90%) having a PD of less than 10%.

Credit risk - Consumer banking (continued)

Consumer banking balances by payment due status

Credit risk in the consumer banking portfolios is primarily monitored and reported based on arrears status which is set out below:

Note:

i. Charged off balances relate to accounts which are closed to future transactions and are held on the balance sheet for an extended period (up to 36 months, depending on the product) whilst recovery procedures take place.

Whilst total balances subject to arrears, excluding charged off balances, have increased to GBP153 million (4 April 2018: GBP149 million) as the portfolios have continued to grow over recent periods, balances subject to arrears as a percentage of total consumer banking lending have reduced to 3.5% (4 April 2018: 3.6%).

Forbearance

Nationwide is committed to supporting customers facing financial difficulty by working with them to find a solution through proactive arrears management and forbearance. The Annual Report and Accounts 2018 sets out further details of concession events included within forbearance.

The table below provides details of consumer banking balances subject to forbearance. These are all assessed as either stage 2 or stage 3 loans:

Notes:

   i.       Loans to registered social landlords are secured on residential property. 

ii. Loans advanced in relation to project finance are secured on cash flows from government or local authority backed contracts.

   iii.    Micro hedged risk relates to loans hedged on an individual basis. 

iv. As a result of their contractual cash flow characteristics, certain commercial loans were reclassified from amortised cost to FVTPL on transition to IFRS 9 on 5 April 2018, and remeasured at fair value.

The project finance and commercial real estate portfolios are closed to new business, whilst the registered social landlord market was re-opened to limited new business in September 2018.

Credit risk in the CRE portfolio continues to reduce as the managed exit of this business continues. Over the period, total balances across the commercial portfolios have decreased, and the performance of the portfolios has remained stable.

Other lending includes GBP409 million of collateral with a central counterparty (4 April 2018: GBP71 million), GBP19 million (4 April 2018: GBPnil) of reverse repos and GBP9 million (4 April 2018: GBP8 million) of deferred consideration receivable relating to the disposal of Visa Europe.

Credit risk - Commercial and other lending (continued)

As at 30 September 2018, 97% (5 April 2018: 96%) of the commercial and other lending balances remain in stage 1. Of the GBP264 million stage 2 loans, GBP1 million (5 April 2018: GBP2 million) is in arrears by 30 days or more. The remainder are in stage 2 due to non-arrears factors such as placement on a watchlist pending full repayment of the balance at or post maturity.

The stage 3 loans in the CRE portfolio total GBP27 million (5 April 2018: GBP37 million), equating to 2% (5 April 2018: 2%) of the total CRE exposure.

Within the registered social landlord portfolio, there are no stage 3 assets, and only 1% (5 April 2018: 1%) of the exposure is in stage 2. Against a backdrop of a long history of zero defaults, the risk profile of the portfolio remains low.

The majority of loans in the project finance portfolio are secured on projects which are now operational and benefiting from secure long-term cash flows.

There is no significant exposure to credit risk on the other lending balances.

Credit quality

Nationwide adopts robust credit management policies and processes designed to recognise and manage the risks arising from the portfolio.

The risk grades in the table above are based upon supervisory slotting criteria, under which exposures are classified into categories depending on the underlying credit risk, with the assessment based upon financial strength, asset characteristics, the strength of the sponsor and the security. The credit quality in the CRE portfolio shown above remains stable, with 95% (5 April 2018: 95%) of the portfolio continuing to be rated as satisfactory or better.

Risk grades for the project finance portfolio are also based upon supervisory slotting criteria, with 97% of the exposure rated strong or good.

The residential social landlord portfolio is risk graded using a PD model. The credit quality remains high, with an average 12 month PD of 0.05% across the portfolio.

In addition to the above, GBP57 million (5 April 2018: GBP58 million) of commercial lending balances are classified as FVTPL, of which GBP53 million (5 April 2018: GBP53 million) relates to CRE loans, with a risk grade of satisfactory.

Notes:

i. A CRE loan may be secured on assets located in different regions; balances are therefore attributed to the region where the majority of the exposure arises. This can lead to re-categorisation occurring between periods if the asset mix changes.

   ii.     Includes lending to borrowers based in the Channel Islands. 

iii. The LTV ratio is calculated using the on-balance sheet carrying amount of the loan divided by the indexed value of the most recent independent external collateral valuation. The Investment Property (IPD) monthly index is used.

The LTV distribution of the CRE portfolio remains stable, with 96% (4 April 2018: 96%) of the portfolio having an LTV of 75% or less.

The changes to the regional distribution of the CRE portfolio reflect the managed reduction of the portfolio.

Credit risk concentration by industry sector

Credit risk exposure by industry sector is unchanged from the year ended 4 April 2018, continuing to be spread across the retail, office, residential, industrial and leisure sectors. Of the GBP1,627 million (4 April 2018: GBP1,868 million) CRE exposures, 45% (4 April 2018: 45%) relates to the residential sector.

CRE balances by payment due status

Of the GBP1,627 million (4 April 2018: GBP1,868 million) CRE exposure, GBP65 million relates to balances with arrears (4 April 2018: GBP52 million). Of the balances with arrears, GBP8 million (4 April 2018: GBP24 million) have arrears greater than 3 months.

Forbearance

Forbearance is recorded and reported at borrower level and applies to all commercial lending, including impaired exposures and borrowers subject to enforcement and recovery action.

The table below provides details of commercial loans that are currently subject to forbearance by concession event. The Annual Report and Accounts 2018 sets out further details of concession events included within forbearance.

Note:

i. Loans where more than one concession event has occurred are reported under the latest event.

Consistent with the European Banking Authority reporting definitions, loans that meet the regulatory forbearance exit criteria are not reported as forborne.

Amortised cost balances subject to forbearance have reduced, reflecting the managed exit activity.

In addition to the amortised cost balances included in the table above, there are GBP57 million FVTPL commercial and other lending balances (5 April 2018: GBP58 million), of which GBP42 million (5 April 2018: GBP42 million) are forborne due to capital concessions.

Credit risk - Treasury assets

Summary

The treasury portfolio is held primarily for liquidity management and, in the case of derivatives, for market risk management. The table below shows the classification of treasury asset balances following the adoption of IFRS 9.

Notes:

i. Treasury assets are subject to credit risk; however for assets classified as FVTPL, provisions are not separately calculated as credit risk is reflected in the carrying value of the asset.

ii. Derivatives are classified as assets where their fair value is positive and liabilities where their fair value is negative. At 30 September 2018, derivative liabilities were GBP1,826 million (4 April 2018: GBP2,337 million).

The increase in cash is driven by an increased flow into savings products. Investment securities held at amortised cost have grown due to the purchase, as part of a consortium, of residential mortgage backed securities under a programme to securitise Bradford and Bingley plc residential mortgage assets.

Credit risk - Treasury assets (continued)

Investment activity, in line with the Board's risk appetite, remains restricted to high quality liquid securities. In addition, the Society invests in highly rated liquid assets that are eligible for accessing central bank funding operations. Derivatives are used to reduce exposure to market risks but are not used for trading or speculative purposes.

Managing treasury credit risks

Credit risk within the treasury portfolio is managed and controlled by the Treasury Credit Risk function in accordance with Nationwide's risk governance frameworks, details of which are provided in the Annual Report and Accounts 2018.

A monthly review is undertaken of the current and expected future performance of all treasury assets and this is used in determining provision requirements for the portfolio. At 30 September 2018 no treasury assets were impaired.

Liquidity and investment portfolio

The liquidity and investment portfolio of GBP36,043 million (4 April 2018: GBP30,829 million) comprises liquid assets and other securities. The size of the portfolio reflects operational and strategic liquidity requirements. An analysis of the on-balance sheet portfolios by asset class, credit rating and geographical location of the issuers is set out below.

Derivative financial instruments

Derivatives are used to reduce exposure to market risks, although the application of accounting rules can create volatility in the income statement in a financial period. The fair value of derivative assets at 30 September 2018 was GBP4.5 billion (4 April 2018: GBP4.1 billion). To comply with EU regulatory requirements, Nationwide, as a direct member of a central counterparty (CCP), has central clearing capability which it uses to clear standardised derivatives.

The International Swaps and Derivatives Association (ISDA) Master Agreement is Nationwide's preferred agreement for documenting derivative transactions. A Credit Support Annex (CSA) is always executed in conjunction with the ISDA Master Agreement. Under the terms of a CSA, collateral is passed between parties to mitigate the market-contingent counterparty risk inherent in the outstanding positions. CSAs are two-way agreements where both parties post collateral dependent on the exposure of the derivative. Collateral is paid or received on a regular basis (typically daily) to mitigate the mark to market exposures.

Credit risk - Treasury assets (continued)

Nationwide's CSA legal documentation for derivatives grants legal rights of set off for transactions with the same overall counterparty. Accordingly, the credit risk associated with such positions is reduced to the extent that negative mark to market values offset positive mark to market values in the calculation of credit risk within each netting agreement. In the event of a default, or other predetermined event, outstanding transactions with the same counterparty can be offset and settled on a net basis. Under CSA arrangements, netting benefits of GBP1.5 billion (4 April 2018: GBP2.0 billion) were available and GBP3.1 billion of collateral (4 April 2018: GBP2.2 billion) was held. Only cash is held as collateral.

The following table shows the exposure to counterparty credit risk for derivative contracts after netting benefits and collateral:

Liquidity and funding risk

Summary

Liquidity risk is the risk that Nationwide is unable to meet its liabilities as they fall due and maintain member and other stakeholder confidence. Funding risk is the risk that Nationwide is unable to maintain diverse funding sources in wholesale and retail markets nor manage the retail funding risk that can arise from excessive concentrations of higher risk deposits.

Nationwide manages liquidity and funding risks within a comprehensive risk framework which includes policies, strategy, limit setting and monitoring, stress testing and robust governance controls. This framework ensures that Nationwide maintains stable and diverse funding sources and sufficient holdings of high quality liquid assets so that there is no significant risk that liabilities cannot be met as they fall due. Further details are included within the Annual Report and Accounts 2018.

Liquidity and funding levels continued to be within Board risk appetite and regulatory requirements throughout the period. This includes the LCR, which ensures that sufficient high quality liquid assets are held to survive a short term severe but plausible liquidity stress. Nationwide's LCR at 30 September 2018 was above the regulatory minimum of 100% and increased to 131.9% (4 April 2018: 130.3%) due to strong retail deposit performance increasing the liquid asset buffer.

Nationwide also monitors its position against the longer term funding metric, the Net Stable Funding Ratio (NSFR). Based on current interpretations of expected regulatory requirements and guidance, the NSFR at 30 September 2018 was 134.4%

(4 April 2018: 131.0%) which exceeds the expected 100% minimum future requirement.

Notes:

   i.      The figures in the above table are stated net of impairment provisions where applicable. 
   ii.     Balances as at 5 April 2018 reflect the impact of applying IFRS 9: Financial Instruments. 

Nationwide's loan to deposit ratio(1) at 30 September 2018 was 123.3% (4 April 2018: 125.5%).

1 The loan to deposit ratio represents loans and advances to customers divided by shares + other deposits + amounts due to customers (excluding repurchase agreements and collateral received).

Liquidity and funding risk (continued)

Wholesale funding

The wholesale funding portfolio is made up of a range of secured and unsecured instruments to ensure Nationwide has a diversified funding base across a range of instruments, currencies, maturities and investor types. Part of Nationwide's wholesale funding strategy is to remain active in core markets and currencies. A funding risk limit framework also ensures a prudent funding mix and maturity concentration profile is maintained, and limits the level of encumbrance to ensure sufficient contingent funding capacity is retained.

Wholesale funding has increased by GBP3.3 billion to GBP62.1 billion during the period. This is primarily due to increased repo activity and deposits. This additional funding is reflected in Nationwide's wholesale funding ratio (on-balance sheet wholesale funding as a proportion of total funding liabilities) which was 28.6% at 30 September 2018 (4 April 2018: 28.2%).

The table below sets out Nationwide's wholesale funding by currency.

Liquidity risk

Liquidity strategy

Nationwide ensures it has sufficient liquid assets, both in terms of amount and quality, to meet daily cash flow needs as well as simulated stressed requirements driven by the Society's risk appetite and regulatory assessments. This includes ensuring the currency composition of the liquid asset buffer is consistent with the currency profile of stressed outflows.

Nationwide's liquid assets are held and managed centrally by its Treasury function. Nationwide maintains a high quality liquidity portfolio, predominantly comprising:

   --    reserves held at central banks; 
   --    highly rated debt securities issued by a restricted range of governments, central banks and supranationals. 

The size and mix of the liquid asset buffer is defined by the Society's risk appetite as set by the Board, which is translated into a set of liquidity risk limits; it is also influenced by other relevant considerations such as stress testing and regulatory requirements. Further details of Nationwide's policies for liquid assets are contained within the Annual Report and Accounts 2018.

Liquid assets

The table below sets out the sterling equivalent fair value of the liquidity portfolio, categorised by issuing currency. It includes off-balance sheet liquidity, such as bonds received through reverse repurchase (repo) agreements, and excludes bonds encumbered through repo agreements.

Notes:

i. The analysis excludes certain non-financial assets (including property, plant and equipment, intangible assets, other assets, deferred tax assets and accrued income and expenses prepaid) and non-financial liabilities (including provisions for liabilities and charges, accruals and deferred income, current tax liabilities, other liabilities and retirement benefit obligations).

   ii.     Due less than one month includes amounts repayable on demand. 

iii. The principal amount for undated subscribed capital is included within the due after more than five years column.

iv. Off-balance sheet commitments include amounts payable on demand for unrecognised loan commitments, customer overpayments on residential mortgages where the borrower is able to draw down the amount overpaid, and commitments to acquire financial assets.

In practice, customer behaviours mean that liabilities are often retained for longer than their contractual maturities and assets are repaid faster. This gives rise to funding mismatches on Nationwide's balance sheet. The balance sheet structure and risks are managed and monitored by Nationwide's Assets and Liabilities Committee (ALCO). Nationwide uses judgement and past behavioural performance of each asset and liability class to forecast likely cash flow requirements.

Asset encumbrance

Encumbrance arises where assets are pledged as collateral against secured funding and other collateralised obligations and therefore cannot be used for other purposes. The majority of asset encumbrance arises from the use of prime mortgage pools to collateralise the Covered Bond and Silverstone secured funding programmes (further information is included in note 11) and from participation in the Bank of England's Term Funding Scheme (TFS).

Certain unencumbered assets are readily available to secure funding or meet collateral requirements. These include prime mortgages and cash and securities held in the liquid asset buffer. Other unencumbered assets, such as non-prime mortgages, are capable of being encumbered with a degree of further management action. Assets which do not fall into either of these categories are classified as not being capable of being encumbered.

At 30 September 2018, Nationwide had GBP33,922 million (4 April 2018: GBP32,633 million) of externally encumbered assets with counterparties other than central banks. Nationwide also had GBP40,243 million (4 April 2018: GBP38,886 million) of pre-positioned and encumbered assets held at central banks and GBP155,129 million (4 April 2018: GBP149,636 million) of assets neither encumbered nor pre-positioned but capable of being encumbered. Further details of Nationwide's policies for asset encumbrance are contained within the Annual Report and Accounts 2018.

External credit ratings

The Group's long-term and short-term credit ratings are shown in the table below. The long-term rating for both Standard & Poor's and Moody's is the senior preferred rating. The long-term rating for Fitch is the senior non-preferred rating.

In October 2018, Moody's affirmed Nationwide's Aa3/P-1 long and short term ratings, but changed its outlook to negative from stable. This change in outlook reflects uncertainties embedded in Moody's forward looking view on the loss given failure of the Society's senior debt. There have been no other credit rating changes since April 2018.

Solvency risk

Solvency risk is the risk that Nationwide fails to maintain sufficient capital to absorb losses throughout a full economic cycle and sufficient to maintain the confidence of current and prospective investors, members, the Board and regulators. Further information on solvency risk and how it is managed can be found in the Annual Report and Accounts 2018 and the Annual Pillar 3 Disclosure 2018 at nationwide.co.uk

Capital position

The capital disclosures included in this report are on a Capital Requirements Directive IV (CRD IV) end point basis. This assumes that all CRD IV requirements are in force during the period, with no transitional CRD IV provisions permitted. However, IFRS 9 transitional arrangements are applied. The arrangements allow for transitional relief to be applied against the impact of IFRS 9 on capital resources, to be scaled over a 5-year transition period, with the full impact being applied from 2023 onwards.

The disclosures below are reported on a consolidated Group basis, including all subsidiary entities, unless otherwise stated.

Notes:

i. Figures have been adjusted to reflect the impact of applying IFRS 9 from 5 April 2018. Further information is provided in our Report on Transition to IFRS 9: Financial Instruments, which can be found on nationwide.co.uk.

ii. The UK leverage ratio is shown on the basis of measurement announced by the Prudential Regulation Authority (PRA). It is calculated using the Capital Requirements Regulation (CRR) definition of Tier 1 for the capital amount and the Delegated Act definition of the exposure measure, excluding eligible central bank reserves.

iii. The Capital Requirements Regulation (CRR) leverage ratio is calculated using the CRR definition of Tier 1 for the capital amount and the Delegated Act definition of the exposure measure.

Our capital resources have continued to strengthen during the period with the CET1 ratio increasing to 31.7% (5 April 2018: 30.4%) and the UK leverage ratio to 5.0% (5 April 2018: 4.9%). Both are comfortably in excess of minimum regulatory capital requirements and Nationwide's strategic target of maintaining a UK leverage ratio of greater than 4.5%.

CET1 capital resources have increased by GBP0.5 billion, primarily due to profit after tax for the period of GBP387 million and a net remeasurement of pension obligations of GBP155 million.

The total regulatory capital ratio has increased to 44.2% (5 April 2018: 42.8%), also due to higher CET1 capital resources. Additional Tier 1 (AT1) and Tier 2 capital resources have remained stable over the period.

Solvency risk (continued)

Detailed information on Nationwide's capital instruments can be found within the Interim Pillar 3 Disclosure 2018, at nationwide.co.uk

Nationwide has been granted permission to report a UK leverage ratio on the basis of measurement announced by the PRA in August 2016. Minimum leverage requirements are monitored by the PRA on this basis.

Lending growth has been more than offset by profits for the period, with Tier 1 resources growing more quickly than leverage exposure. This resulted in the UK leverage ratio increasing to 5.0%. The CRR leverage ratio has remained stable at 4.6%.

Further details on the leverage exposure can be found in the Group's Interim Pillar 3 Disclosure 2018 at nationwide.co.uk

Nationwide's latest Pillar 2A Individual Capital Requirement (ICR) and Total Capital Requirement (TCR) were received in September 2018. The ICR is the Pillar 2A capital requirement while the TCR is the sum of our Pillar 1 and Pillar 2A requirements. These replace the former Internal Capital Guidance (ICG). The ICR equates to circa GBP2.4 billion, of which at least circa GBP1.4 billion must be met by CET1 capital. The ICR was equivalent to 7.4% of RWAs as at 30 September 2018 (4 April 2018: 7.1%), largely reflecting the low average risk weight, given that approximately 76% (4 April 2018: 78%) of total assets are in the form of secured residential mortgages.

The table below reconciles the general reserves to total regulatory capital on an end-point basis and so does not include non-qualifying instruments.

Notes:

i. Foreseeable distributions in respect of CCDS and AT1 securities are deducted from CET1 capital under CRD IV.

ii. A prudent valuation adjustment (PVA) is applied in respect of fair valued instruments as required under regulatory capital rules.

iii. Own credit and debit valuation adjustments are applied to remove balance sheet gains or losses of fair valued liabilities and derivatives that result from changes in Nationwide's own credit standing and risk, in accordance with CRD IV rules.

iv. Intangible assets and goodwill do not qualify as capital for regulatory purposes.

v. The net regulatory capital expected loss in excess of accounting impairment provisions is deducted from CET1 capital, gross of tax. The net excess of impairment provisions over regulatory capital expected loss is added to Tier 2 capital, gross of tax. The expected loss amounts for equity exposures and general and specific credit risk adjustments related to these exposures are not included in the calculation, as per Article 159 of CRR. The expected loss amounts for equity exposures are deducted from CET1 capital, gross of tax.

vi. The transitional adjustments to capital resources apply scaled relief for the impact of IFRS 9, over a 5-year transition period. Further information on these adjustments is provided in the Interim Pillar 3 disclosures.

vii. Subordinated debt includes fair value adjustments related to changes in market interest rates, adjustments for unamortised premiums and discounts that are included in the consolidated balance sheet, and any amortisation of the capital value of Tier 2 instruments required by regulatory rules for instruments with fewer than five years to maturity.

Solvency risk (continued)

As part of the Bank Recovery and Resolution Directive (BRRD), the Bank of England, in its capacity as the UK resolution authority, has published its policy for setting the minimum requirement for eligible liabilities (MREL) and provided firms with indicative MREL. From 1 January 2020, it is anticipated that Nationwide will be subject to a requirement to hold twice the minimum capital requirements (6.5% of UK leverage exposure), plus the applicable capital requirement buffers, which are currently expected to amount to 0.75% of UK leverage exposure. In order to meet this pending requirement, Nationwide issued a further GBP0.7 billion of senior non-preferred notes in July 2018 which are MREL eligible.

At 30 September 2018, total MREL resources were equal to 8.0% of UK leverage ratio exposure (4 April 2018: 7.5%), above the anticipated 2020 requirement described previously.

Risk weighted assets

The table below shows the breakdown of risk weighted asset (RWAs) by risk type and business activity. Market risk has been set to zero as permitted by the CRR, as the exposure is below the threshold of 2% of own funds.

Notes:

i. This column includes credit risk exposures, counterparty credit risk exposures and deferred tax assets that are below the thresholds for deduction and instead are subject to a 250% risk weight.

ii. RWAs have been allocated according to the business lines within the standardised approach to operational risk, as per article 317 of CRR.

iii. Counterparty credit risk relates to derivative financial instruments and securities financing transactions (SFTs).

Risk weighted assets (RWAs) have increased by GBP0.4 billion over the period. This is primarily due to an increase of GBP0.6 billion in RWAs for counterparty credit risk, driven by a relative weakening of sterling against other currencies increasing our derivative exposure, and a GBP0.4 billion increase in exposure in the 'other' assets category. These were partly offset by a GBP0.7 billion decrease in commercial RWAs due to the portfolio run off. Details on how RWAs are calculated can be found in the Group's annual Pillar 3 Disclosure 2018 at nationwide.co.uk

Regulatory developments

Nationwide is currently required to maintain a minimum leverage ratio of 3.45% following the implementation of a 0.2% countercyclical buffer in June 2018. The countercyclical buffer increases to 0.4% from November 2018. There is also an additional leverage ratio buffer to be implemented in 2019, expected to be 0.35%. Therefore, the minimum leverage ratio requirement is expected to be 4% by January 2019. Nationwide is confident it is in a strong position to meet the minimum requirements.

The Basel Committee published their final reforms to the Basel III framework in December 2017. The rules are subject to a lengthy transitional period. Further information can be found in the Solvency risk section of the Annual Report and Accounts 2018.

Pension risk

Nationwide has funding obligations to defined benefit pension schemes, the most significant being the Nationwide Pension Fund (the Fund). Further information is set out in the Annual Report and Accounts 2018.

The Fund's net defined benefit liability (deficit) which appears within liabilities on the balance sheet, has decreased from GBP345 million to GBP83 million in the period. The reduction in the Fund's deficit since 4 April 2018 is largely due to improving market conditions combined with an employer deficit contribution of GBP61 million agreed as part of the 2016 triennial valuation. Further information is included in note 19.

The Trustees and Nationwide have taken actions which are expected to have a positive long-term impact on the volatility of the Fund's deficit. During the period, the Fund progressed its liability hedging strategy and invested GBP310 million in index-linked and conventional gilts, to further reduce its exposure to inflation and interest rate risk.

GMP Equalisation

On 5 July 2018, a coalition, formed of Lloyds Banking Group, Lloyds Trade Union and the Lloyds pension scheme trustees began to seek the High Court's input on whether the trustees of their pension schemes should equalise Guaranteed Minimum Pension (GMP) between females and males and, if so, how this should be undertaken.

On 26 October 2018 the verdict from the High Court confirmed that GMPs must be equalised and arrears paid. Although the case is specific to the Lloyds pension schemes, the verdict will impact all defined benefit pension schemes (including the Nationwide Pension Fund) that contracted out of the state second pension between 1978 and 1997, substituting members' state second pensions for GMP. The High Court judgement also commented on the method of equalisation.

The verdict will result in an increase in the Nationwide Pension Fund's retirement benefit obligation; the exact impact is currently being assessed but is not expected to be material. Nationwide will continue to monitor developments in relation to GMP; the increased financial obligation is expected to be recognised as a charge in Q3 2018/19.

Operational risk

Nationwide's recently announced investment in new technology, skills and capabilities will help to ensure that we are able to continue to provide secure and resilient systems and processes that deliver significant benefits for our customers. A transformation of this scale necessarily creates operational risks and these will be closely monitored and managed.

We have seen an increase in the frequency and sophistication of cyber attacks being made against the Society. This is not unique to Nationwide, and reflects the increased activity, sophistication and severity of attacks across the UK. We continue to evaluate our cyber security and resilience against the emerging threat landscape, updating our defensive capabilities accordingly.

Protecting our members from becoming victims of fraud and scams continues to be a priority for Nationwide. Specifically, in the area of Authorised Push Payment scams, we continue to work with industry peers, consumer groups, regulators and the Financial Ombudsman Service (FOS) to create and implement a more effective framework in which to manage the increasing threat of customers being duped into authorising transactions by criminals.

Conduct and compliance risk

The General Data Protection Regulation (GDPR) came into force in May 2018. Following this, consumer awareness about personal data rights has increased and we have experienced a rise in Subject Access Requests, in line with the industry. Nationwide will continue to maintain its focus on meeting the GDPR requirements and safeguarding members' data protection and privacy.

Notes to the consolidated interim financial statements

1 General information and reporting period

Nationwide Building Society ('the Society') and its subsidiaries (together, 'the Group') provide financial services to retail and commercial customers within the United Kingdom.

Nationwide is a building society incorporated and domiciled in the United Kingdom. The address of its registered office is Nationwide Building Society, Nationwide House, Pipers Way, Swindon, SN38 1NW.

There were no material changes in the composition of the Group in the half year to 30 September 2018.

These condensed consolidated interim financial statements ('consolidated interim financial statements') have been prepared as at 30 September 2018 and show the financial performance for the period from, and including, 5 April 2018 to this date. They were approved for issue on 21 November 2018.

These consolidated interim financial statements have been reviewed, not audited.

2 Basis of preparation

The consolidated interim financial statements of the Group for the half year ended 30 September 2018 have been prepared in accordance with the Disclosure and Transparency Rules of the Financial Conduct Authority and with International Accounting Standard (IAS) 34 'Interim Financial Reporting' as adopted by the EU. The consolidated interim financial statements should be read in conjunction with the Group's annual financial statements for the year ended 4 April 2018, which were prepared in accordance with International Financial Reporting Standards (IFRSs) as adopted by the EU.

Terminology used in these consolidated interim financial statements is consistent with that used in the Annual Report and Accounts 2018. Copies of the Annual Report and Accounts 2018 and Glossary are available on the Group's website at nationwide.co.uk

Accounting policies

The accounting policies adopted by the Group in the preparation of these consolidated interim financial statements and those which the Group currently expects to adopt in the Annual Report and Accounts 2019 are consistent with those disclosed in the Annual Report and Accounts 2018, except in relation to the adoption of the following new standards:

   --      IFRS 9 'Financial Instruments' 
   --      IFRS 15 'Revenue from Contracts with Customers'. 

Further information on the impacts of adopting these new standards is set out below, including revised accounting policies in relation to IFRS 9. Additional information on the transition to IFRS 9 can be found in the Nationwide's 'Report on Transition to IFRS 9: Financial Instruments', available on the Society's website at nationwide.co.uk. This report also includes a glossary containing definitions of terms relevant to IFRS 9.

In addition, a number of amendments and improvements to accounting standards have been issued by the International Accounting Standards Board (IASB) with an effective date of 1 January 2018. Those relevant to these consolidated interim financial statements, being minor amendments to IFRS 2 'Classification and Measurement of Share-based Payment Transactions' and IAS 40 'Transfers of Investment Property', were adopted with no significant impact for the Group.

Note:

i. Certain assets previously classified as available for sale have been reclassified as fair value through profit or loss, resulting in an adjustment to the general reserve of GBP13 million.

The policies for financial assets and impairment of financial assets have changed from 5 April 2018 following the adoption of IFRS 9; the revised policies are set out below.

IFRS 9 also includes updated requirements for the general hedge accounting model, which covers hedge accounting in the instances where a single item or a closed portfolio of items is the hedged risk. The IASB is currently working on a project for open portfolios, otherwise known as macro hedges. Until this project is completed, an entity can choose to continue using IAS 39 for all hedge accounting requirements, or adopt IFRS 9 for general hedge accounting and continue using the IAS 39 approach for macro hedges. The Group is currently using IAS 39 for all of its hedge accounting requirements.

Financial assets

Financial assets comprise cash, loans and advances to banks, investment securities, derivative financial instruments and loans and advances to customers.

Recognition and derecognition

All financial assets are recognised initially at fair value. Purchases and sales of financial assets are accounted for at trade date. Financial assets acquired through a business combination or portfolio acquisition are recognised at fair value at the acquisition date.

Financial assets are derecognised when the rights to receive cash flows have expired or where the assets have been transferred and substantially all the risks and rewards of ownership have been transferred.

Notes to the consolidated interim financial statements (continued)

2 Basis of preparation (continued)

IFRS 9 'Financial Instruments' (continued)

The fair value of a financial instrument on initial recognition is normally the transaction price (plus directly attributable transaction costs for financial assets which are not subsequently measured at fair value through profit or loss). On initial recognition, it is presumed that the transaction price is the fair value unless there is observable information available in an active market to the contrary. Any difference between the fair value at initial recognition and the transaction price is recognised immediately as a gain or loss in the income statement where the fair value is based on a quoted price in an active market or a valuation using only observable market data. In all other cases, any gain or loss is deferred and recognised over the life of the transaction, or until valuation inputs become observable.

Modification of contractual terms

An instrument that is renegotiated is derecognised if the existing agreement is cancelled and a new agreement is made on substantially different terms (such as renegotiations of commercial loans). Residential mortgages reaching the end of a fixed interest deal period are deemed repricing events, rather than a modification of contractual terms, as the change in interest rate at the end of the fixed rate period was envisaged in the original mortgage contract.

Where an instrument is renegotiated and not derecognised (for example forbearance), the change is considered a modification of contractual terms. Where this arises, the gross carrying amount of the loan is recalculated as the present value of the renegotiated or modified contractual cash flows, discounted at the loan's original effective interest rate. Any gain or loss on recalculation is recognised immediately in the income statement.

Classification and measurement

The classification and subsequent measurement of financial assets is based on an assessment of the Group's business models for managing the assets and their contractual cash flow characteristics. Financial assets are classified into the following three categories:

(a) Amortised cost

Financial assets held to collect contractual cash flows and where contractual terms comprise solely payments of principal and interest (SPPI) are classified as amortised cost. This category of financial assets includes cash, loans and advances to banks, the majority of the Group's residential and commercial mortgage loans, all unsecured lending, and certain investment securities within a 'hold to collect' business model.

Financial assets within this category are recognised on either the receipt of cash or deposit of funds into one of the Group's bank accounts (for cash and loans and advances to banks), when the funds are advanced to borrowers (for residential, commercial and unsecured lending) or on the trade date for purchases of investment securities. After initial recognition, the assets are measured at amortised cost using the effective interest rate method, less provisions for expected credit losses.

(b) Fair value through other comprehensive income

Financial assets held in a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and where contractual terms comprise solely payments of principal and interest, are classified and measured at fair value through other comprehensive income (FVOCI). This category of financial assets includes most of the Group's investment securities which are held to manage liquidity requirements.

Financial assets within this category are recognised on trade date. The assets are measured at fair value using, in the majority of cases, market prices or, where there is no active market, prices obtained from market participants. In sourcing valuations, the Group makes use of a consensus pricing service, in line with standard industry practice. In cases where market prices or prices from market participants are not available, discounted cash flow models are used.

Interest on FVOCI assets is recognised in interest receivable and similar income in the income statement, using the effective interest rate method.

Unrealised gains and losses arising from changes in value are recognised in other comprehensive income. Provisions for expected credit losses and foreign exchange gains or losses are recognised in the income statement.

Cumulative gains or losses arising on sale are recognised in the income statement, net of any credit or foreign exchange gains or losses already recognised.

2 Basis of preparation (continued)

IFRS 9 'Financial Instruments' (continued)

(c) Fair value through profit or loss

All other financial assets are measured at fair value through profit or loss (FVTPL). Financial assets within this category include derivative instruments and a small number of residential and commercial loans and investment securities with contractual cash flow characteristics which do not meet the SPPI criteria. The contractual terms for these cash flows include contingent or leverage features, or returns based on movements in underlying collateral values such as house prices.

Fair values are based on observable market data, valuations obtained by third parties or, where these are not available, internal models. All interest income and gains or losses arising from the changes in the fair value of these instruments and on disposal are recognised in the income statement.

Hedge accounting is not applied to assets classified as FVTPL.

Impairment of financial assets

Financial assets within the scope of IFRS 9 expected credit loss (ECL) requirements comprise all financial debt instruments measured at either amortised cost or FVOCI. These include cash, loans and advances to banks, and the majority of investment securities and loans and advances to customers. Also within scope are irrevocable undrawn commitments to lend and intra-group lending (the latter being eliminated on consolidation in the Group accounts).

The ECL represents the present value of expected cash shortfalls following the default of a financial instrument or undrawn commitment. A cash shortfall is the difference between the cash flows that are due in accordance with the contractual terms of the instrument and the cash flows that the Group expects to receive.

The allowance for ECLs is based on an assessment of the probability of default, exposure at default and loss given default, discounted at the effective interest rate to give a net present value. The estimation of ECLs is unbiased and probability weighted, taking into account all reasonable and supportable information, including forward looking economic assumptions and a range of possible outcomes. ECLs are typically calculated from initial recognition of the financial asset for the maximum contractual period that the Group is exposed to the credit risk. However, for revolving credit loans such as credit cards and overdrafts, the Group's credit risk is not limited to the contractual period and therefore the expected life of the loan and associated undrawn commitment is calculated based on the behavioural life of the loan.

For amortised cost financial assets recognised in the balance sheet, the allowance for ECLs is offset against the gross carrying value so that the amount presented in the balance sheet is net of impairment provisions. For FVOCI financial assets, any credit losses recognised are offset against cumulative fair value movements within the other comprehensive income reserve. For separately identifiable irrevocable loan commitments, where the related financial asset has not yet been advanced, the provision is presented in provisions for other liabilities and charges in the balance sheet.

Forward looking economic inputs

ECLs are calculated by reference to information on past events, current conditions and forecasts of future economic conditions. Multiple economic scenarios are incorporated into ECL calculation models. These scenarios are based on external sources where available and appropriate, and internally generated assumptions in all other cases. To capture any non-linear relationship between economic assumptions and credit losses, a minimum of three scenarios is used. This includes a central scenario which reflects the Group's view of the most likely future economic conditions, together with an upside and a downside scenario representing alternative plausible views of economic conditions, weighted based on management's view of their probability.

Credit risk categorisation

For the purpose of calculation of ECLs, assets are categorised into three 'stages' as follows:

Stage 1: no significant increase in credit risk since initial recognition

On initial recognition, and for financial assets where there has not been a significant increase in credit risk since the date of advance, provision is made for losses from credit default events expected to occur within the next 12 months. Expected credit losses for these stage 1 assets continue to be recognised on this basis unless there is a significant increase in the credit risk of the asset.

2 Basis of preparation (continued)

IFRS 9 'Financial Instruments' (continued)

Stage 2: significant increase in credit risk

Financial assets are categorised as being within stage 2 where an instrument has experienced a significant increase in credit risk since initial recognition. For these assets, provision is made for losses from credit default events expected to occur over the lifetime of the instrument.

Whether a significant increase in credit risk has occurred is ascertained by comparing the probability of default at the reporting date to the probability of default at origination, and is made based on quantitative and qualitative factors. Quantitative considerations take into account changes in the residual lifetime probability of default (PD) of the asset. As a backstop, all assets with an arrears status of more than 30 days past due on contractual payments are considered to be in stage 2.

Qualitative factors that may indicate a significant change in credit risk include concession events that still envisage full repayment of principal and interest, on a discounted basis.

Stage 3: credit impaired (or defaulted) loans

Financial assets are transferred into stage 3 when there is objective evidence that an instrument is credit impaired. Provisions for stage 3 assets are made on the basis of lifetime expected credit losses. Assets are considered credit impaired when:

   --      contractual payments of either principal or interest are past due by more than 90 days; 

-- there are other indications that the borrower is unlikely to pay such as signs of financial difficulty, probable bankruptcy, breaches of contract and concession events which have a detrimental impact on the present value of future cashflows; or

   --      the loan is otherwise considered to be in default. 

Interest income on stage 3 credit impaired loans is recognised in the income statement on the loan balance net of the ECL provision. The balance sheet value of stage 3 loans reflects the contractual terms of the assets, and continues to increase over time with the contractually accrued interest.

Purchased or originated credit impaired (POCI) loans

Where loans are credit impaired on origination, or when purchased from third parties, the carrying amount at initial recognition is net of the lifetime ECL at that date. Thereafter, any subsequent change (favourable or unfavourable) in the lifetime ECL is recognised in the income statement. POCI loans are separately disclosed as credit impaired loans and cannot be transferred out of the POCI designation, even if there is a significant improvement in credit quality.

Transfers between stages

Transfers from stage 1 to 2 occur when there has been a significant increase in credit risk and from stage 2 to 3 when credit impairment is indicated as described above.

For assets in stage 2 or 3, loans can transfer back to stage 1 or 2 once the criteria for a significant increase in credit risk or impairment are no longer met. For loans subject to concession events such as forbearance, accounts must first be up to date for a period of 12 months before they can transfer back to stage 1 or 2.

Write-off

Loans remain on the balance sheet net of associated provisions until they are deemed to have no reasonable expectations of recovery. Where a loan is not recoverable, it is written off against the related provision for loan impairment once all the necessary procedures have been completed and the amount of the loss has been determined. Subsequent recoveries of amounts previously written off decrease the value of impairment losses recorded in the income statement.

IFRS 15 'Revenue from Contracts with Customers'

The Group has applied IFRS 15 'Revenue from Contracts with Customers' from 5 April 2018. The standard applies to all contracts with customers but does not apply to financial instruments, lease contracts or non-monetary exchanges. IFRS 15 has introduced a principles-based approach for revenue recognition, with revenue being recognised as the related obligations are satisfied.

The Group has assessed revenue streams within the scope of IFRS 15 and concluded that the timing of revenue recognition is unchanged under the new standard. There is therefore no transitional impact from adopting this standard.

Adjustments to comparative information

Interest paid on liabilities arising from financing activities

In the cash flow statement, interest paid on debt securities in issue, subordinated liabilities and subscribed capital has previously been included in cash flows from operating activities. Interest paid on these liabilities is now presented within cash flows from financing activities to better reflect the nature of the interest flows. Comparatives have been restated as shown below:

This restatement has no impact on the Group's or Society's net assets or members' interests and equity, or cash and cash equivalents.

Future accounting developments

An overview of pronouncements that will be relevant to the Group in future periods can be found in the Annual Report and Accounts 2018.

Judgements in applying accounting policies and critical accounting estimates

The Group has to make judgements in applying its accounting policies which affect the amounts recognised in these consolidated interim financial statements. In addition, estimates and assumptions are made that could affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based upon amounts which differ from those estimates.

Other than in relation to the implementation of IFRS 9 'Financial Instruments', there have been no changes to the significant judgements and estimates disclosed in the Annual Report and Accounts 2018.

To ensure that expected credit loss (ECL) provisions fulfil IFRS 9 requirements, judgement and estimation is required in a number of areas. The areas where the impact of judgement and estimation are most material are:

-- the approach to identifying significant increases in credit risk and the definition of default

   --      the basis of forward looking information and multiple economic scenarios 
   --      the proportion of interest only mortgages that will redeem or refinance at maturity. 

The Group's approach to each of these judgements is described in more detail below.

Notes to the consolidated interim financial statements (continued)

2 Basis of preparation (continued)

Identifying significant increases in credit risk (stage 2)

The identification of significant increases in credit risk is the most judgemental element of the staging criteria. Management monitors the Group's loans to determine whether there have been changes in credit risk. The primary quantitative indicators are the outputs of internal credit risk assessments. For example, for retail exposures, PDs are derived using modelled scorecards, which use external information such as information from credit reference agencies as well as internal information such as known instances of arrears or other financial difficulty. While different approaches are used within each portfolio, the intention is to combine current and historical data relating to the exposure with forward-looking macroeconomic information to determine the likelihood of default.

The credit risk of each loan is evaluated at each reporting date by calculating the residual lifetime PD of each loan. For retail loans, the main indicators of a significant increase in credit risk are either of the following:

-- the residual lifetime probability of default (PD) exceeds a benchmark determined by reference to the maximum credit risk that would have been accepted at origination

-- the residual lifetime PD has increased by both at least 75bps and a multiple of the original lifetime PD (8x for mortgages, 4x for consumer banking).

These complementary criteria have been reviewed through detailed back-testing, using management performance indicators and actual default experience and found to be effective in capturing events which would constitute a significant increase in credit risk.

Identifying credit impaired loans and the definition of default (stage 3)

The identification of credit impaired loans and the definition of default is another important judgement within the IFRS 9 staging approach. A loan is credit impaired where it has an arrears status of more than 90 days past due, is considered to be in default or it is considered unlikely that the borrower will repay the credit obligations in full, without recourse to actions such as realising security.

Use of forward looking economic information

Forward looking economic information is incorporated into the measurement of provisions in two ways: as an input to the calculation of ECL and as a factor in determining the staging of an asset. Expectations of future economic conditions are incorporated through modelling of multiple economic scenarios (MES).

The use of MES ensures that the calculation of ECL captures a range of possible outcomes. It addresses the risk of non-linearity in the relationship between credit losses and economic conditions, with provisions increasing more in unfavourable conditions (particularly severe conditions) than they reduce in favourable conditions. The IFRS 9 ECL provision reported in the accounts is therefore the probability-weighted sum of the provisions calculated under a range of economic scenarios.

For the retail and commercial portfolios, the Group has adopted the use of three economic scenarios (referred to as the central, upside and downside scenarios). The scenarios and the weightings are derived using external data and statistical methodologies, together with management judgement, to determine scenarios which span an appropriately wide range of plausible economic conditions.

The central scenario represents the most likely economic forecast and is aligned with the central scenario used in the Group's financial planning processes. At 5 April 2018 and 30 September 2018 this scenario is assigned a 50% probability weighting. The upside and downside economic scenarios are less likely and have been given 20% and 30% weightings respectively (5 April 2018 30% and 20% respectively).

Notes to the consolidated interim financial statements (continued)

2 Basis of preparation (continued)

The table below provides a summary of the average values of the key UK economic variables used within the three economic scenarios over the period from October 2018 to September 2023.

 
Economic variables (average 
 %) 
                                Central scenario  Upside scenario  Downside scenario 
GDP growth                                   1.6              2.3                0.7 
Unemployment                                 4.4              3.8                5.5 
HPI                                          2.1              5.0              (2.8) 
BoE Base Rate                                0.9              2.0                0.2 
 
 

The impact of the economic variables varies according to the portfolio. For example, mortgages are most sensitive to house prices, whereas consumer banking products are more sensitive to unemployment rates.

Due to the net adverse impact of the less likely scenarios, the ECL increases under MES, as outlined in the table below:

In addition to the three economic scenarios, allowance has been made to reflect the risks associated with a low probability, severe downside scenario. The quantification of this allowance included consideration of a number of different scenarios and reflects a scenario in which real GDP growth over a five year period is slightly negative, unemployment rises sharply and house prices fall significantly. At 30 September 2018, this additional allowance represents GBP86 million (5 April 2018: GBP85 million) of the total GBP126 million (5 April 2018: GBP110 million) MES impact.

Performance at maturity of interest only mortgages

The third key area of management judgement and estimation is the allowance for the risk that a proportion of interest only mortgages will not be redeemed at the contractual maturity date, because a borrower does not have a means of capital repayment or has been unable to refinance the loan. Buy to let mortgages are typically advanced on an interest only basis. Interest only balances for prime residential mortgages relate primarily to historical balances which were originally advanced as interest only mortgages or where a change in terms to an interest only basis was agreed (this option was withdrawn in 2012). The impact of the allowance for unredeemed interest only mortgages at contractual maturity in the central scenario amounts to GBP50 million (5 April 2018: GBP58 million), with an additional impact of GBP17 million (5 April 2018: GBP16 million) arising from multiple economic scenarios.

Interest only loans which are judged to have a significantly increased risk of inability to refinance at maturity are transferred to stage 2.

Going concern

The Group's business activities and financial position, the factors likely to affect its future development and performance, its objectives and policies in managing the financial risks to which it is exposed, and its capital, funding and liquidity positions are discussed in the Business and risk report.

In the light of current and anticipated economic conditions, the directors have assessed the Group's ability to continue as a going concern. The directors confirm they are satisfied that the Group has adequate resources to continue in business and that it is therefore appropriate to adopt the going concern basis in preparing these consolidated interim financial statements.

6 Gains from derivatives and hedge accounting

The Group has taken the option allowed by IFRS 9 to continue to apply the existing hedge accounting requirements of IAS 39.

The Group only uses derivatives for the hedging of risks; however, income statement volatility can arise due to hedge accounting ineffectiveness or because hedge accounting is either not currently applied or is not achievable. The overall impact of derivatives will remain volatile from period to period as new derivative transactions replace those which mature to ensure that interest rate and other market risks are continually managed. This volatility does not reflect the economic reality of the Group's hedging strategy.

Notes:

i. Gains or losses from fair value hedges can arise where there is a hedge accounting relationship in place and either:

-- the relationship passed all the monthly effectiveness tests but the fair value movement of the derivative was not exactly offset by the change in fair value of the asset or liability being hedged (referred to as hedge ineffectiveness); or

-- the relationship failed a monthly effectiveness test which, for that month, disallows recognition of the change in fair value of the underlying asset or liability being hedged and in following months leads to the amortisation of existing balance sheet positions.

ii. In cash flow hedge accounting, where monthly effectiveness tests are passed, the effective portion of the fair value movement of designated derivatives (being the lower of the fair value movement of the derivative or the hedged item) is deferred to the cash flow hedge reserve. The fair value movement is subsequently recycled to the income statement when amounts relating to the underlying hedged asset or liability are recognised in the income statement. The ineffective portion of the fair value movement is recognised immediately in the income statement.

iii. Includes the fair value movement of both interest rate swaps, which are used to economically hedge expected new mortgage business, and firm mortgage commitments, where the Group has elected to fair value those commitments to reduce the accounting mismatch. The Group has not applied this fair value option for new mortgage business in the current period; therefore, the fair value movements of the interest rate swaps are now reported in 'fair value losses from other derivatives'.

iv. Other derivatives are those used for economic hedging purposes, but which are not currently in a hedge accounting relationship.

v. Gains or losses arise from the retranslation of foreign currency monetary items not subject to effective hedge accounting.

The deferral of fair value movements to the cash flow hedge reserve, and the transfer of amounts from the cash flow hedge reserve to the income statement, are shown in the consolidated statement of comprehensive income. The net transfer after taxation of losses of GBP65 million (H1 2017/18: GBP114 million) is driven by changes in derivative valuations caused by movements in interest rates and foreign exchange rates.

The issuance proceeds are used to purchase, for the benefit of note holders, a share of the beneficial interest in the mortgages pledged by the Group. The remaining beneficial interest in the pledged mortgages of GBP4.9 billion (4 April 2018: GBP5.2 billion) stays with the Group and includes its required minimum seller share in accordance with the rules of the programme. During the period ended 30 September 2018 no notes were issued and a total of GBP0.4 billion sterling equivalent of notes matured.

Mortgages pledged include GBP8.5 billion (4 April 2018: GBP8.7 billion) in the covered bond and securitisation programmes that are in excess of the amount contractually required to support notes in issue.

The whole mortgage loan pools are pledged at the BoE under the TFS.

Notes to the consolidated interim financial statements (continued)

12 Subordinated liabilities and subscribed capital (continued)

As part of the ongoing funding strategy, the Group issued $1 billion (GBP761 million) and Norwegian Kroner 1 billion (GBP94 million) of subordinated notes during the period. GBP3 million of permanent interest-bearing shares (PIBS) were repaid in full during the period.

All of the Group's subordinated notes and PIBS are unsecured. The Group may, with the prior consent of the Prudential Regulation Authority (PRA), repay the PIBS and redeem the subordinated notes early.

Subordinated liabilities comprise senior non-preferred notes and Tier 2 subordinated notes.

The senior non-preferred notes rank pari passu with each other and behind the claims against the Society of all depositors, creditors and investing members other than holders of Tier 2 subordinated notes, PIBS, Additional Tier 1 (AT1) capital and core capital deferred shares (CCDS) of the Society.

The Tier 2 subordinated notes rank pari passu with each other and behind the claims against the Society of all depositors, creditors and investing members other than holders of PIBS, AT1 capital and CCDS of the Society.

The PIBS rank pari passu with each other and the AT1 instruments, behind claims against the Society of the subordinated noteholders, depositors, creditors and investing members, but ahead of claims by the holders of CCDS.

13 Fair value hierarchy of financial assets and liabilities held at fair value

IFRS 13 requires an entity to classify assets and liabilities held at fair value, and those not measured at fair value but for which the fair value is disclosed, according to a hierarchy that reflects the significance of observable market inputs in calculating those fair values. The three levels of the fair value hierarchy are defined in note 1 of the Annual Report and Accounts 2018.

Details of those financial assets and liabilities not measured at fair value are included in note 15.

The following tables show the Group's financial assets and liabilities that are held at fair value by fair value hierarchy, balance sheet classification and product type:

Notes:

i. Investment securities exclude GBP1,748 million of investment securities held at amortised cost (4 April 2018: GBP1,120 million of held to maturity investment securities and GBP1 million of available for sale investments in equity shares).

ii. On transition to IFRS 9, certain loans and advances to customers have been classified as FVTPL. Further information is included in note 2.

The Group's Level 1 portfolio comprises government and other highly rated securities for which traded prices are readily available.

Asset valuations for Level 2 investment securities are sourced from consensus pricing or other observable market prices. None of the Level 2 investment securities are valued from models. Level 2 derivative assets and liabilities are valued from discounted cash flow models using yield curves based on observable market data. Level 2 loans and advances to customers are valued based on discounted cashflows or by reference to similar assets in markets which are not active.

Further detail on the Level 3 portfolio is provided in note 14.

Transfers between fair value hierarchies

Instruments move between fair value hierarchies primarily due to increases or decreases in market activity or changes to the significance of unobservable inputs to their valuation. There were no significant transfers between the Level 1 and Level 2 portfolios during the period.

14 Fair value of financial assets and liabilities held at fair value - Level 3 portfolio

On transition to IFRS 9, certain loans and advances to customers have been classified as FVTPL. Level 3 assets in this category include a closed portfolio of residential mortgages and a small number of commercial loans. During the period, a portfolio of residential mortgages was transferred from Level 3 to Level 2 due to changes in the availability of observable market prices.

The remaining constituents of the Level 3 portfolio at 30 September 2018 are consistent with those disclosed in the Group's 2018 Annual Report and Accounts.

Level 3 portfolio sensitivity analysis of valuations using unobservable inputs

The fair value of financial instruments is, in certain circumstances, measured using valuation techniques based on market prices that are not observable in an active market or on significant unobservable market inputs.

Reasonable alternative assumptions can be applied for sensitivity analysis, taking account of the nature of valuation techniques used, as well as the availability and reliability of observable proxy and historic data. The following table shows the sensitivity of the Level 3 fair values to reasonable alternative assumptions (as set out in the table of significant unobservable inputs below) and the resultant impact of such changes in fair value on the income statement or members' interests and equity:

Notes:

i. On adoption of IFRS 9 the Level 3 investment securities were classified as fair value through profit or loss. The sensitivity analysis on fair values in the table above therefore impacts the income statement in the current period. At 4 April 2018 Level 3 investment securities were available for sale assets, with fair value movements recognised in other comprehensive income.

ii. A sensitivity analysis for Level 3 derivative instruments has not been included due to immateriality.

Alternative assumptions are considered for each product and varied according to the quality of the data and variability of the underlying market.

The following table discloses the significant unobservable inputs underlying the above alternative assumptions for assets and liabilities recognised at fair value and classified as Level 3, along with the range of values for those significant unobservable inputs.

Notes:

   i.       The table above excludes cash for which fair value approximates to carrying value. 

ii. The Group holds residential mortgage backed securities under a programme to securitise Bradford & Bingley plc residential mortgage assets. These financial assets are classified as amortised cost in the current period; at 4 April 2018 they were classified as held to maturity investment securities.

16 Offsetting financial assets and financial liabilities

The Group has financial assets and financial liabilities for which there is a legally enforceable right to set off the recognised amounts, and there is an intention to settle on a net basis, or realise the asset and liability simultaneously. In accordance with IAS 32 'Financial Instruments: Presentation', where the right to set off is not unconditional in all circumstances this does not result in an offset of balance sheet assets and liabilities.

In accordance with IFRS 7 'Financial Instruments: Disclosures', the following table shows the impact of offsetting on financial assets and financial liabilities, where:

-- there is an enforceable master netting arrangement or similar agreement in place and an unconditional right to offset is in place ('amounts offset'),

-- there is an enforceable master netting arrangement or similar agreement in place but the offset criteria are otherwise not satisfied ('master netting arrangements'), and

   --      financial collateral is paid and received ('financial collateral')

Note:

i. Amounts offset for derivative financial assets of GBP377 million (4 April 2018: GBP167 million) include cash collateral netted of GBP144 million (4 April 2018: GBP3 million). Amounts offset for derivative financial liabilities of GBP317 million (4 April 2018: GBP169 million) include cash collateral netted of GBP84 million (4 April 2018: GBP5 million). Excluding the cash collateral netted, the remaining amounts represent GBP233 million (4 April 2017: GBP164 million) of derivative financial assets and derivative financial liabilities which are offset.

Master netting arrangements consist of agreements such as an ISDA Master Agreement, global master repurchase agreements and global master securities lending agreements, whereby outstanding transactions with the same counterparty can be offset and settled net, either unconditionally or following a default or other predetermined event.

Financial collateral on derivative financial instruments consists of cash posted, typically daily or weekly, to mitigate the mark to market exposures. Financial collateral on repurchase agreements typically comprises highly liquid securities which are legally transferred and can be liquidated in the event of counterparty default.

The net amounts after offsetting under IFRS 7 presented above show the exposure to counterparty credit risk for derivative contracts after netting benefits and collateral, and are not intended to represent the Group's actual exposure to credit risk. This is due to a variety of credit mitigation strategies which are employed in addition to netting and collateral arrangements.

Notes:

i. On transition to IFRS 9, an Expected Credit Loss provision of GBP1 million was recognised in respect of separately identifiable irrevocable loan commitments.

ii. Of the net income statement release of GBP19 million (H1 2017/18: charge of GBP18 million), a release of GBP24 million (H1 2017/18: net charge of GBP22 million) is recognised in provisions for liabilities and charges and a charge of GBP5 million (H1 2017/18: release of GBP4 million) is recognised in administrative expenses.

Financial Services Compensation Scheme (FSCS)

The FSCS has confirmed that there will be no further interest costs following the sale of Bradford & Bingley plc asset portfolios and subsequent repayment of the loan to HM Treasury. Interest costs in respect of the 2017/18 and 2018/19 scheme years were included in the provision at 4 April 2018.

The income statement release of GBP9 million reflects the lower than anticipated interest costs following receipt of additional recoveries from the administration of Bradford & Bingley plc.

Customer redress

During the course of its business, the Group receives complaints from customers in relation to past sales or conduct. The Group is also subject to enquiries from and discussions with its regulators, governmental and other public bodies, including the Financial Ombudsman Service (FOS), on a range of matters. Customer redress provisions are recognised where the Group considers it is probable that payments will be made as a result of such complaints and other matters.

The Group holds provisions of GBP167 million (4 April 2018: GBP221 million) in respect of the potential costs of remediation and redress in relation to historic sales of financial products and post sales administration. This includes amounts for past sales of PPI, non-compliance with consumer credit legislation and other regulatory matters. The net income release in the period reflects updated assumptions for provisions previously recognised.

It is considered appropriate for the Group to provide for the estimated total amount required to deal with all ongoing and future PPI complaints. The amount provided for PPI at 30 September 2018 of GBP116 million (4 April 2018: GBP159 million) therefore reflects the compensation and administrative costs associated with cases that the Group expects to uphold and the cost of processing invalid claims which the Group expects to receive. The provision estimate takes into account complaint volumes, average redress payments, referral rates to the Financial Ombudsman Service (FOS), uphold rates, complaint handling costs and response rates from customer contact activity. The principal uncertainty in this calculation is the impact of the ongoing FCA media campaign on complaints volumes in advance of the complaints deadline of August 2019.

Notes to the consolidated interim financial statements (continued)

The table below shows the sensitivity of the PPI provision to changes in complaints volumes, along with other significant assumptions used in calculating the provision:

Notes:

   i.     Claims include responses to proactive mailing. 

ii. The cumulative average uphold rate of claims includes responses to past proactive mailings. As a result, future expected average uphold rates are forecast to decline as no further proactive mailing activity is anticipated.

iii. Future expected average redress reflects the expected mix of future claims upheld.

Other provisions

Other provisions include provisions for severance costs, a number of property related provisions and expected credit losses on irrevocable personal loan and mortgage lending commitments.

18 Contingent liabilities

The Group's contingent liability accounting policy is included within the Annual Report and Accounts 2018. Where it is concluded that it is more likely than not that a payment will be made a provision is recognised based on management's best estimate of the amount that will be payable. For other matters no provision is recognised but disclosure is made of items which are potentially material, either individually or in aggregate, except in cases where the likelihood of a liability crystallising is considered to be remote. Currently the Group does not expect the ultimate resolution of any such matters to have a material adverse impact on its financial position.

These pension schemes are principally unchanged from the year ended 4 April 2018; further details are set out in note 30 of the Annual Report and Accounts 2018.

The principal actuarial assumptions used are as follows:

Consumer price index (CPI) inflation            2.20     2.10 
 

The assumptions for mortality rates are based on up to date industry standard mortality tables, which allow for future improvements in life expectancies.

Deficit at 30 September                                    83           262 
 

Note:

i. The net impact before tax on the deficit of actuarial gains and return on assets is an increase of GBP212 million (H1 2017/18: GBP97 million) in other comprehensive income.

The GBP182 million of actuarial gains (H1 2017/18: GBP226 million) on defined benefit obligations is driven by a 0.20% increase in the discount rate and a 0.10% increase in assumed long term inflation since 4 April 2018, as a result of changes in market conditions.

The GBP30 million decrease in the deficit from a return on assets greater than the discount rate (H1 2017/18: GBP129 million deficit increase from a return less than the discount rate), is driven by changes in market conditions positively impacting listed equities.

The GBP96 million of employer contributions includes a deficit contribution of GBP61 million in July 2018 (H1 2017/18: GBP86 million). The remainder relates to employer contributions in respect of future benefit accrual.

CCDS are a form of Common Equity Tier 1 (CET1) capital which have been developed to enable the Group to raise capital from the capital markets. Previously issued Tier 1 capital instruments, PIBS, no longer meet the regulatory capital requirements of CRD IV and are being gradually phased out of the calculation of capital resources under transitional rules.

CCDS are perpetual instruments. They rank pari passu to each other and are junior to claims against the Society of all depositors, creditors and investing members. Each holder of CCDS has one vote, regardless of the number of CCDS held.

In the event of a winding up or dissolution of the Society and if there was surplus available, the amount that the investor would receive for each CCDS held is limited to the average principal amount in issue, which is currently GBP129.24 per share.

There is a cap placed on the amount of distributions that can be paid to holders of CCDS in any financial year. The cap is currently set at GBP16.06 per share and is adjusted annually in line with CPI.

A final distribution of GBP54 million (GBP5.125 per share) for the financial year ended 4 April 2018 was paid on 20 June 2018. This distribution has been recognised in the consolidated statement of movements in members' interests and equity.

Since the balance sheet date the directors have declared a distribution of GBP5.125 per share in respect of the period to 30 September 2018, amounting in aggregate to GBP54 million. This has not been reflected in these interim financial statements as it is recognised by reference to the date at which it was declared. The distribution will be paid on 20 December 2018.

21 Other equity instruments

 
                         Total 
                          GBPm 
At 30 September 2018       992 
At 4 April 2018            992 
 

Other equity instruments are Additional Tier 1 (AT1) capital instruments. AT1 instruments rank pari passu to each other and to PIBS. They are junior to claims against the Society of all depositors, creditors and investing members, other than the holders of CCDS.

AT1 instruments pay a fully discretionary, non-cumulative fixed coupon at an initial rate of 6.875% per annum. The rate will reset on 20 June 2019 and every five years thereafter to the five year mid swap rate plus 4.88%. Coupons are paid semi-annually in June and December.

A coupon of GBP34 million, covering the period to 19 June 2018, was paid on 20 June 2018. This payment has been recognised in the consolidated statement of movements in members' interests and equity.

A coupon payment of GBP34 million, covering the period to 19 December 2018, is expected to be paid on 20 December 2018. This is not reflected in these interim financial statements as it is recognised by reference to the date at which it is paid.

The coupons paid and declared represent the maximum non-cumulative fixed coupon of 6.875%.

AT1 instruments have no maturity date. They are repayable at the option of the Society on 20 June 2019 and on every fifth anniversary thereafter. AT1 instruments are only repayable with the consent of the PRA.

If the fully loaded CET1 ratio for the Society, on either a consolidated or unconsolidated basis, falls below 7% the AT1 instruments convert to CCDS instruments at the rate of one CCDS share for every GBP80 of AT1 holding.

22 Related party transactions

There were no related party transactions during the period ended 30 September 2018 which were significant to the Group's financial position or performance.

Full details of the Group's related party transactions for the year to 4 April 2018 can be found in note 35 of the Annual Report and Accounts 2018.

The Group is required to maintain balances with the Bank of England and certain other central banks which, at 30 September 2018, amounted to GBP553 million (30 September 2017: GBP344 million). These balances are included within loans and advances to banks on the balance sheet and are not included in the cash and cash equivalents in the cash flow statement as they are not liquid in nature.

24 Event after the reporting period

On 26 October 2018, the High Court issued a judgement in a case between Lloyds Banking Group Pension Trustees Limited, Lloyds Bank plc and other defendants regarding inequalities in the calculation of Guaranteed Minimum Pensions (GMP) between females and males. The judgement concluded that the benefits of females and males in relation to GMPs should be equalised. Although the case is specific to the Lloyds pension schemes, the verdict will impact all defined benefit pension schemes (including the Nationwide Pension Fund) that contracted out of the state second pension between 1978 and 1997, substituting members' state second pensions for GMP. The High Court judgement also commented on the method to be adopted to equalise benefits.

The verdict will result in an increase in the Nationwide Pension Fund's retirement benefit obligation and is expected to be recognised as a charge to the income statement during Q3 2018/19. Work is ongoing to determine the impact, which is not expected to be material.

Responsibility statement

The directors listed below (being all the directors of Nationwide Building Society) confirm that, to the best of their knowledge:

-- the consolidated interim financial statements have been prepared in accordance with International Accounting Standard 34, 'Interim Financial Reporting', as adopted by the European Union

Independent review report to Nationwide Building Society

Report on the consolidated interim financial statements

Our conclusion

We have reviewed the consolidated interim financial statements (the "interim financial statements") for Nationwide Building Society and its subsidiaries ("the Group") on pages 47 to 77 in the Interim Results of Nationwide Building Society for the six month period ended 30 September 2018 (the "Interim Results"). Based on our review, nothing has come to our attention that causes us to believe that the interim financial statements are not prepared, in all material respects, in accordance with International Accounting Standard 34, 'Interim Financial Reporting', as adopted by the European Union and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority.

What we have reviewed

The interim financial statements comprise:

   --      the consolidated balance sheet as at 30 September 2018; 

-- the consolidated income statement and consolidated statement of comprehensive income for the period then ended;

   --      the consolidated cash flow statement for the period then ended; 

-- the consolidated statement of movements in members' interests and equity for the period then ended; and

   --      the explanatory notes to the interim financial statements. 

The interim financial statements included in the Interim Results have been prepared in accordance with International Accounting Standard 34, 'Interim Financial Reporting', as adopted by the European Union and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority.

As disclosed in note 2 to the interim financial statements, the financial reporting framework that has been applied in the preparation of the full annual financial statements of the Group is applicable law and International Financial Reporting Standards (IFRSs) as adopted by the European Union.

Responsibilities for the interim financial statements and the review

Our responsibilities and those of the directors

The Interim Results, including the interim financial statements, is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the Interim Results in accordance with the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority.

Our responsibility is to express a conclusion on the interim financial statements in the Interim Results based on our review. This report, including the conclusion, has been prepared for and only for the Group for the purpose of complying with the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority and for no other purpose. We do not, in giving this conclusion, accept or assume responsibility for any other purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed by our prior consent in writing.

What a review of interim financial statements involves

We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) 2410, 'Review of Interim Financial Information Performed by the Independent Auditor of the Entity' issued by the Auditing Practices Board for use in the United Kingdom. A review of interim financial information consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures.

A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK) and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

We have read the other information contained in the Interim Results and considered whether it contains any apparent misstatements or material inconsistencies with the information in the interim financial statements.
