In March 2016, the FASB issued Accounting Standards Update No. 2016-08, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross verses Net)</font><font style="font-family:inherit;font-size:10pt;">, or ASU 2016-08. These amendments provide additional clarification and implementation guidance on the previously issued Accounting Standards Update No. 2014-09, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers (Topic 606)</font><font style="font-family:inherit;font-size:10pt;">, or ASU 2014-09. The amendments in ASU 2016-10 provide clarifying guidance on materiality of performance obligations; evaluating distinct performance obligations; treatment of shipping and handling costs; and determining whether an entity's promise to grant a license provides a customer with either a right to use an entity's intellectual property or a right to access an entity's intellectual property. The amendments in ASU 2016-08 clarify how an entity should identify the specified good or service for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements. The adoption of ASU 2016-10 and ASU 2016-08 is to coincide with an entity's adoption of ASU 2014-09, which we intend to adopt for interim and annual reporting periods beginning after December 15, 2017. We are currently evaluating the impact that these standards will have on our results of operations, cash flows, consolidated financial position and related disclosures.</font></div><div style="line-height:120%;padding-bottom:12px;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In March 2016, the FASB issued Accounting Standards Update No. 2016-09, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting</font><font style="font-family:inherit;font-size:10pt;">, or ASU 2016-09. The amendments in this update simplify several aspects of accounting for and reporting on share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments in ASU 2016-09 are effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The various amendments are to be applied differently upon adoption with certain amendments being applied prospectively, retrospectively and under a modified retrospective transition method. We are currently evaluating the effects the adoption of ASU 2016-09 will have on our consolidated financial statements, results of operations and cash flows.</font></div><div style="line-height:120%;padding-bottom:12px;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued Accounting Standards Update No. 2016-02, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Leases (Topic 842)</font><font style="font-family:inherit;font-size:10pt;">, or ASU 2016-02. Upon the effective date, ASU 2016-02 will supersede the current lease guidance in Topic 840, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Leases</font><font style="font-family:inherit;font-size:10pt;">. Under the new guidance, lessees will be required to recognize for all leases, with the exception of short-term leases, a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis. Concurrently, lessees will be required to recognize a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be applied using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative periods presented in the financial statements. We are currently evaluating the effects the adoption of ASU 2016-02 will have on our consolidated financial statements, results of operations and cash flows.</font></div><div style="line-height:120%;padding-bottom:16px;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">There were no other new accounting pronouncements that were issued or became effective since the issuance of our 2015 Annual Report on Form 10-K that had, or are expected to have, a material impact on our consolidated financial position, results of operations or cash flows.</font></div></div>
