Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation We prepared this Quarterly Report on Form 10-Q under the rules and regulations of the United States Securities and Exchange Commission (SEC) and in accordance with United States generally accepted accounting principles (U.S. GAAP) as it applies to interim financial statements. Because this is an interim period report presented using a condensed format, it does not include all of the disclosures required by U.S. GAAP and should be read along with our 2014 Annual Report on Form 10-K. The condensed consolidated financial statements as of September 30, 2015 and 2014 are unaudited. The consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated balance sheet included in our 2014 Annual Report on Form 10-K.

New Accounting Pronouncements Issued But Not Yet Adopted The following accounting standards have been issued but not yet been adopted. Business Combinations. In September 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement - Period Adjustments, which eliminates the requirement for an acquirer in a business combination to retrospectively adjust prior period financial statements for adjustments to the initial purchase price allocation that are identified between the acquisition date and when the purchase price allocation is finalized. Prospective application of this standard is required beginning after December 15, 2015 and early adoption is allowed. Debt Issuance Costs. In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which will require us to present unamortized debt issue costs on our balance sheet as a direct deduction from the associated debt liability. In August 2015, the FASB issued ASU No. 2015-15, Interest- Imputation of Interest, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which clarifies that an entity may defer and present debt issue costs related to line-of-credit arrangements as an asset regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. Retrospective application of these standards is required beginning in the first quarter of 2016 and early adoption is allowed. Revenue Recognition. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common revenue standard for U.S. GAAP and International Financial Reporting Standards. In July 2015, the FASB approved the deferral of the new revenue standard by one year, with the option of early adoption in 2017 or, if not adopted early, beginning in the first quarter of 2018. Retrospective application of this standard is required upon adoption. We are currently evaluating the impact, if any, that this update will have on our financial statements.

Basis of Presentation and Significant Accounting Policies

Basis of Presentation

We prepared this Quarterly Report on Form 10-Q under the rules and regulations of the United States Securities and Exchange Commission (SEC) and in accordance with United States generally accepted accounting principles (U.S. GAAP) as it applies to interim financial statements. Because this is an interim period report presented using a condensed format, it does not include all of the disclosures required by U.S. GAAP and should be read along with our 2014 Annual Report on

Form 10-K. The condensed consolidated financial statements as of September 30, 2015 and 2014 are unaudited. The consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated balance sheet included in our 2014 Annual Report on Form 10-K. In our opinion, all adjustments which are of a normal, recurring nature are reflected to fairly present these interim period results. The results for any interim period are not necessarily indicative of the expected results for the entire year.

Significant Accounting Policies

There were no changes in significant accounting policies as described in the 2014 Annual Report on Form 10-K.

New Accounting Pronouncements Issued But Not Yet Adopted

The following accounting standards have been issued but not yet been adopted.

Business Combinations. In September 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement - Period Adjustments, which eliminates the requirement for an acquirer in a business combination to retrospectively adjust prior period financial statements for adjustments to the initial purchase price allocation that are identified between the acquisition date and when the purchase price allocation is finalized.

In August 2015, the FASB issued ASU No. 2015-15, Interest- Imputation of Interest, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which clarifies that an entity may defer and present debt issue costs related to line-of-credit arrangements as an asset regardless of whether there are any outstanding borrowings on the line-of-credit arrangement.
