Adoption of Accounting Standards and Updates

(2)    Adoption of Accounting Standards and Updates

We are required to prepare our consolidated financial statements in accordance with the Financial Accounting Standards Board's (“FASB”) Accounting Standards Codification (“ASC”) which is the source for all authoritative U.S. generally accepted accounting principles, which is commonly referred to as “GAAP.” The FASB ASC is subject to updates by FASB, which are known as Accounting Standards Updates (“ASUs”).

On August 1, 2013, we adopted FASB ASU No. 2011-11, which requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement. In addition, we also adopted ASU No. 2013-01, which clarifies that the scope of ASU No. 2011-11 applies to derivatives accounted for in accordance with Topic 815, "Derivatives and Hedging," including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset or subject to an enforceable master netting arrangement or similar arrangement. Our adoption of this ASU, as amended, did not have any impact on our consolidated financial statements.
