New Financial Accounting Standards	Jun. 30, 2014
New Financial Accounting Standards	Note O — New Financial Accounting Standards In April 2014, the Financial Accounting Standards Board (FASB) issued new amendments on reporting discontinued operations through Accounting Standards Update (ASU) No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in this update revise the definition of a discontinued operation as a disposal of a component of an entity or a group of components of an entity, or a business or nonprofit activity that represents a strategic shift that has or will have a major effect on an entity’s operations and financial results. The amendments also require additional disclosures for discontinued operations and individually significant disposals that do not qualify for discontinued operations presentation in the financial statements. For public entities, the amendments are effective prospectively for reporting periods beginning on or after December 15, 2014. The application of this guidance is not expected to have a material impact on the Companies’ financial position, results of operations and liquidity. In May 2014, the FASB and the International Accounting Standards Board (IASB) jointly issued a new revenue recognition standard that will supersede the revenue recognition requirements within Accounting Standards Codification (ASC) Topic 605, “Revenue Recognition,” and most industry-specific guidance under the Codification through ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” The purpose of the new guidance is to create a consistent framework for revenue recognition. The guidance clarifies how to measure and recognize revenue arising from customer contracts to depict the transfer of goods or services in an amount that reflects the consideration the entity expects to receive. The new guidance must be adopted using either a full retrospective approach or a modified retrospective approach. For public entities reporting under US GAAP, the new guidance is effective for periods beginning after December 15, 2016. 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. In June 2014, the FASB issued ASU No. 2014-12, “Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force).” The purpose of the amendments is to clarify the accounting treatment regarding performance targets. Under the new guidance, a performance target that affects vesting and that could be achieved after the requisite service period is required to be treated as a performance condition and should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized only when it becomes probable that the performance target will be achieved. The amendments are effective for periods beginning after December 15, 2015. 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.
