Williams Partners Announces Quarterly Cash Distribution

Williams Partners L.P. (NYSE: WPZ) today announced a regular quarterly cash distribution of $0.85 per unit for its common unitholders.

The board of directors of the partnership's general partner has approved the quarterly cash distribution, which is payable on Feb. 10, 2017, to common unitholders of record at the close of business on Feb. 3, 2017.

This announcement is intended to be a qualified notice to nominees under Treasury Regulation Section 1.1446-4(b)(4) and (d). The partnership’s distributions to foreign investors, which are attributable to income that is effectively connected with a U.S. trade or business, are subject to withholding under U.S. law. In light of the uncertainty at the time of making distributions regarding the portion of any distribution that is attributable to income that is not effectively connected with a U.S. trade or business, we treat all of our distributions as attributable to U.S. operations. Accordingly, the entire amount of the partnership's distributions to foreign investors is subject to federal income tax withholding at the highest effective tax rate. Nominees, and not Williams Partners L.P., are treated as withholding agents responsible for withholding on the distributions received by them on behalf of foreign investors.
