Accounting Developments	Accounting Standards Update (“ASU” or “Update”) 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (April 2015) This Update is part of an initiative to reduce complexity in accounting standards (the “Simplification Initiative”) implemented by the Financial Accounting Standards Board. The objective of the Simplification Initiative is to identify, evaluate, and improve areas of GAAP for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. To simplify presentation of debt issuance costs, the amendments in this Update require 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, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. The amendments in this Update should be applied retrospectively to all periods presented, beginning after December 15, 2015. Adoption of the ASU is not expected to have a significant effect on the Company’s consolidated financial statements.
