These costs, included within selling, general and administrative expenses, were $12.8 million and $11.7 million for the three months ended June 30, 2015 and 2014, respectively, and $25.8 million and $23.0 million for the six months ended June 30, 2015 and 2014, respectively. The Company includes outbound freight costs associated with shipping goods to customers as a component of cost of goods sold. Management Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update which supersedes the most current revenue recognition requirements. The new revenue recognition standard requires entities to recognize revenue in a way that depicts the transfer of goods or services to customers in an amount that reflects the consideration which the entity expects to be entitled to in exchange for those goods or services. This guidance is currently effective for annual and interim reporting periods beginning after December 15, 2016, with early adoption not permitted. In April 2015, the FASB approved a one-year deferral of the effective date of the new revenue recognition standard. The new standard will become effective for annual and interim periods beginning after December 15, 2017 with early adoption as of the original effective date permitted. The Company is currently evaluating this standard to determine the impact of its adoption on its consolidated financial statements. In February 2015, the FASB issued an Accounting Standard Update which amends the current consolidation guidance. This guidance is effective for annual reporting periods beginning after December 15, 2015 and interim reporting periods within fiscal years beginning after December 15, 2016, with early adoption permitted. The Company does not expect the adoption of this standard to have a significant impact on its consolidated financial statements. In April 2015, the FASB issued an Accounting Standard Update which requires all costs incurred to issue debt to be presented in the balance sheet as a direct deduction from the carrying value of the debt. This guidance is effective for annual and interim reporting periods beginning after December 15, 2015, with early adoption permitted. The Company does not expect the adoption of this standard to have a significant impact on its consolidated financial statements. In July 2015, the FASB issued an Accounting Standard Update which simplifies the measurement of inventory by requiring certain inventory to be measured at the lower of cost or net realizable value. This guidance is effective for fiscal years beginning after December 15, 2016 and for interim periods therein. The Company is currently evaluating this standard to determine the impact of its adoption on its consolidated financial statements. Recently Adopted Accounting Standards In January 2015, the FASB issued an Accounting Standards Update which eliminates from GAAP the concept of extraordinary items and the need to separately classify, present, and disclose extraordinary events and transactions. This guidance is effective for annual and interim reporting periods beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The adoption of this pronouncement did not have a material impact on the Company's consolidated financial statements.
