Long-Term Debt
Issuances and retirements
On April 3, 2017, Northwest Pipeline issued $250 million of 4.0 percent senior unsecured notes due 2027 to investors in a private debt placement. Northwest Pipeline used the net proceeds to retire $185 million of 5.95 percent senior unsecured notes that matured on April 15, 2017, which are classified as long-term in the accompanying Consolidated Balance Sheet due to Northwest Pipeline’s intent and ability to refinance, and for general corporate purposes. As part of the new issuance, Northwest Pipeline entered into a registration rights agreement with the initial purchasers of the unsecured notes. Northwest Pipeline is obligated to file and consummate a registration statement for an offer to exchange the notes for a new issue of substantially identical notes registered under the Securities Act of 1933, as amended, within 365 days from closing and to use commercially reasonable efforts to complete the exchange offer. Northwest Pipeline is required to provide a shelf registration statement to cover resales of the notes under certain circumstances. If Northwest Pipeline fails to fulfill these obligations, additional interest will accrue on the affected securities. The rate of additional interest will be 0.25 percent per annum on the principal amount of the affected securities for the first 90-day period immediately following the occurrence of a registration default, increasing by an additional 0.25 percent per annum with respect to each subsequent 90-day period thereafter, up to a maximum amount for all such registration defaults of 0.5 percent annually. Following the cure of any registration defaults, the accrual of additional interest will cease.
On February 23, 2017, utilizing proceeds received from the Financial Repositioning (see Note 1 – General, Description of Business, and Basis of Presentation), WPZ early retired $750 million of 6.125 percent senior unsecured notes that were due in 2022.
WPZ retired $600 million of 7.25 percent senior unsecured notes that matured on February 1, 2017.
