Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment. The guidance removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. Under ASU 2017-04, goodwill impairment will be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance becomes effective for annual reporting periods beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted, and applied prospectively. The Company is currently evaluating this guidance and its impact on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other than Inventory. The guidance requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The guidance becomes effective for annual reporting periods beginning after December 15, 2017 and interim periods within those fiscal years, with early adoption permitted. This ASU is required to be adopted using the modified retrospective approach, with a cumulative catch-up adjustment to retained earnings in the period of adoption. The Company is in the process of determining the timing of adoption and assessing the impact of ASU 2016-16 on its consolidated statements of cash flows. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. The amendments in ASU 2016-15 are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is in the process of determining the timing of adoption and assessing the impact of ASU 2016-15 on its consolidated statements of cash flows. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, forfeitures, statutory tax withholding requirements and classification on the statement of cash flows. The Company adopted ASU 2016-09 in the first quarter of 2017. The adoption resulted in an increase to the net operating loss carryforward deferred tax asset and a corresponding valuation allowance of $9.6 million attributable to excess tax benefits not previously recognized as they did not reduce income taxes payable. The Company historically accounted for excess tax benefits on the statement of cash flows as a financing activity. Upon adoption of this standard, excess tax benefits for the three and six months ended June 30, 2016 totaling $0.6 million and $1.1 million, respectively, are classified along with other income tax cash flows as an operating activity. The Company has elected to adopt this portion of the standard on a prospective basis beginning in 2017. Prior periods have not been adjusted. The presentation requirement for cash flows related to taxes paid for withheld shares had no impact on any of the periods presented in the condensed consolidated statement of cash flows since such payments have historically been presented as a financing activity. The Company elected to continue to estimate forfeitures over the service period of the award, rather than as they occur. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires a lessee to recognize on its balance sheet the assets and liabilities for the rights and obligations created by leases with a lease term of more than twelve months. Leases will continue to be classified as either financing or operating, with classification affecting the recognition, measurement and presentation of expenses and cash flows arising from a lease. Lessor accounting is largely unchanged from previous GAAP. However, changes were made to align the guidance with the lessor guidance and the new revenue recognition guidance under ASU 2014-09 referenced below. For public business entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and requires a modified retrospective approach to adoption for lessees related to capital and operating leases existing at, or entered into after, the earliest comparative period presented in the financial statements. Early adoption is permitted. The Company is in the process of determining the timing and method of adoption as well as assessing the impact of ASU 2016-02 on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled in exchange for those goods or services. To achieve this core principle, ASU 2014-09 contains a five-step model that includes identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations, and recognizing revenue when (or as) an entity satisfies a performance obligation. ASU 2014-09 requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. ASU 2016-10 provides for amendments to ASU 2014-09, reducing the complexity when applying the guidance for identifying performance obligations and improving the operability and understandability of the license implementation guidance. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. ASU 2016-12 provides for amendments to ASU 2014-09, amending the guidance on transition, collectability, noncash consideration and the presentation of sales and other similar taxes. ASU 2016-12 clarifies that, for a contract to be considered completed at transition, all (or substantially all) of the revenue must have been recognized under legacy U.S. GAAP. In addition, ASU 2016-12 clarifies how an entity should evaluate the collectability threshold and when an entity can recognize nonrefundable consideration received as revenue if an arrangement does not meet the standard’s contract criteria. In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which makes minor corrections or minor improvements to ASU 2014-09 that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. Under ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, issued in August 2015, these amendments are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, and either the full retrospective method or the modified retrospective transition method is allowed. The Company will adopt the guidance for the fiscal year beginning after December 15, 2017 and apply the modified retrospective method. The modified retrospective method requires the disclosure of the difference between revenue and costs that would have been recognized under U.S. GAAP in the current period and the amounts that are recognized under the new standard. While a significant portion of the Company’s revenue will continue to be in the scope of the leasing guidance, the Company is in the process of reviewing its sales contracts to identify any other changes as a result of the new guidance. The Company expects to complete its analysis by the end of the third quarter of 2017 and does not expect significant changes. The Company is not aware of other significant matters that will result from its adoption of the revenue standard. The Company has considered all other recently issued accounting pronouncements and does not believe they are of significance, or potential significance, to the Company.
