New Financial Accounting Standards	Note N — New Financial Accounting Standards In January 2015, the Financial Accounting Standards Board (FASB) issued amendments on income statement guidance through Accounting Standards Update (ASU) No. 2015-01, “Income Statement—Extraordinary and Unusual Items (Subtopic 225-20).” The amendments reduce the complexity of accounting standards related to the income statement by eliminating the requirement to report extraordinary items separately. The amendments are effective for reporting periods beginning on or after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The application of this guidance is not expected to have a material impact on the Companies’ financial position, results of operations and liquidity. In February 2015, the FASB issued amendments on consolidation guidance through ASU No. 2015-02, “Consolidation (Topic 810).” The amendments provide additional guidance for VIE accounting of limited partnerships and similar legal entities, fees paid to decision makers of a VIE, the effect of fee arrangements on primary beneficiary determination, the effect of related parties on primary beneficiary determination. For public entities, the amendments are effective prospectively for reporting periods beginning on or after December 15, 2015. Early adoption is permitted. The Companies are evaluating the application and impact of the new guidance on the Companies’ financial position, results of operations and liquidity. In April 2015, the FASB issued amendments on debt issuance costs guidance through ASU No. 2015-03, “Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The amendments provide additional guidance requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability rather than as a deferred cost (i.e. an asset) as required by current guidance. For public entities, the amendments are effective for reporting periods beginning after December 15, 2015. Early adoption is permitted. The Companies are in the process of evaluating the application and impact of the new guidance on the Companies’ financial position, results of operations and liquidity.

If the arrangement is not deemed to contain a software license, it would be accounted for as a service contract. For public entities, the amendments are effective for reporting periods beginning after December 15, 2015. Early adoption is permitted. The Companies are in the process of evaluating the application and impact of the new guidance on the Companies’ financial position, results of operations and liquidity.
