The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. For public companies, this update was to be effective for interim and annual periods beginning after December 15, 2016. However, in August 2015, the FASB issued ASU 2015-14, which delayed the effective date of ASU 2014-09 by one year and permits companies to voluntarily adopt the new standard as of the original effective date. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements, but does not expect the guidance to have a material impact on the Company’s consolidated financial statements.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In September 2015, the FASB issued ASU 2015-16, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Simplifying the Accounting for Measurement-Period Adjustments</font><font style="font-family:inherit;font-size:10pt;">. the amendments in ASU 2015-16 require that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer is required to also record, in the same period’s financial statements, the effect on earnings as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, an entity is required to present separately on the face of the income statement or disclose in the notes to the financial statements the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The amendments in ASU 2015-16 are effective for years beginning after December 15, 2015. Early adoption is permitted for reporting periods for which financial statements have not been issued. The Company adopted the amendments in ASU 2015-16 during the current quarter.</font></div></div>
