"The 3 cent increase is a significant one-time recognition of the dropdown of U.S. assets from the general partner, and going forward, unitholders can expect at least a 1 cent per unit increase per quarter through 2015." This information is intended to be a qualified notice under Treasury Regulation Section 1.1446-4(b). Under rules applicable to publicly-traded partnerships, our distributions to non-U.S. unitholders are subject to withholding tax at the highest effective applicable rate to the extent attributable to income that is effectively connected with the conduct of a U.S. trade or business. Given the uncertainty at the time of making distributions regarding the amount of any distribution that is attributable to income that is so effectively connected, we intend to treat all of our distributions as attributable to our U.S. operations, and as a result, the entire distribution will be subject to withholding.
