New Accounting Pronouncements	(20) New Accounting Pronouncements In January 2014, the FASB issued guidance on the accounting for service concession arrangements with public sector entities. This guidance specifies that an operating entity should not account for a service concession arrangement as a lease and the infrastructure used in a service concession arrangement should not be recognized as property, plant and equipment. This guidance applies when the public sector entity controls the services that the operating entity must provide within the infrastructure and also controls any residual interest in the infrastructure at the end of the term of the arrangement. We are currently evaluating the impact of this guidance, which is effective for reporting periods beginning after December 15, 2014, on our consolidated financial statements. On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
