Description of Business and Significant Accounting Policies
Basis of Presentation	Basis of Presentation We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although we believe that the disclosures are adequate to enable a reasonable understanding of the information presented. The information in this Quarterly Report on Form 10-Q should be read in conjunction with Part I, Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016 (the “2016 Form 10-K”). Certain amounts in the prior year’s financial statements have been reclassified for consistent presentation. The accompanying unaudited consolidated financial statements are prepared consistent with the accounting policies described in Note 1 to the consolidated financial statements included in our 2016 Form 10-K with the exception of the adoption of Accounting Standards Update (“ASU”) 2016-09, “Improvements to Employee Share-Based Payment Accounting,” effective January 1, 2017. As required by this ASU, excess tax benefits and tax shortfalls resulting from share-based compensation are recognized as income tax benefit or expense in the income statement on a prospective basis. Additionally, excess tax benefits or shortfalls recognized on share-based compensation are classified as an operating activity in the statement of cash flows. The Company has applied this provision prospectively, and thus, the prior period presented in the statement of cash flows has not been adjusted. This ASU allows entities to withhold shares issued during the settlement of a stock award or option, as a means of meeting minimum tax withholding due by the employee, in an amount up to the employees’ maximum individual tax rate in the relevant jurisdiction without resulting in a liability classification of the award. The value of the withheld shares is then remitted by the Company in cash to the taxing authorities on the employees’ behalf. The Company’s historical policy to withhold shares equivalent to the minimum individual tax rate is consistent with the thresholds meeting the classification of an equity award and, therefore, a retrospective classification adjustment was not required. This ASU requires that all cash payments made to taxing authorities on the employees’ behalf for withheld shares be presented as financing activities on the statement of cash flows. As this requirement is consistent with the Company’s historical accounting policy, a retrospective adjustment to presentation of the statement of cash flows was not required. This standard also allows for the option to account for forfeitures as they occur when determining the amount of share-based compensation expense to be recognized, rather than estimating expected forfeitures over the course of a vesting period. The Company elected to account for forfeitures as they occur. The net cumulative effect to the Company from the adoption of this ASU was an increase to additional paid-in capital of $3.5 million, a reduction to retained earnings of $2.2 million and an increase to the non-current deferred tax asset of $1.3 million as of January 1, 2017. In our opinion, the accompanying unaudited consolidated financial statements reflect all adjustments (consisting of only a normal and recurring nature) necessary to present fairly our financial position at June 30, 2017, and the results of operations and cash flows for the six months ended June 30, 2017 and 2016 in conformity with accounting principles generally accepted in the United States.

Basis of Presentation

We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although we believe that the disclosures are adequate to enable a reasonable understanding of the information presented. The information in this Quarterly Report on Form 10-Q should be read in conjunction with Part I, Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016 (the “2016 Form 10-K”). Certain amounts in the prior year’s financial statements have been reclassified for consistent presentation.

The accompanying unaudited consolidated financial statements are prepared consistent with the accounting policies described in Note 1 to the consolidated financial statements included in our 2016 Form 10-K with the exception of the adoption of Accounting Standards Update (“ASU”) 2016-09, “Improvements to Employee Share-Based Payment Accounting,” effective January 1, 2017. As required by this ASU, excess tax benefits and tax shortfalls resulting from share-based compensation are recognized as income tax benefit or expense in the income statement on a prospective basis. Additionally, excess tax benefits or shortfalls recognized on share-based compensation are classified as an operating activity in the statement of cash flows.

This ASU allows entities to withhold shares issued during the settlement of a stock award or option, as a means of meeting minimum tax withholding due by the employee, in an amount up to the employees’ maximum individual tax rate in the relevant jurisdiction without resulting in a liability classification of the award.

In our opinion, the accompanying unaudited consolidated financial statements reflect all adjustments (consisting of only a normal and recurring nature) necessary to present fairly our financial position at June 30, 2017, and the results of operations and cash flows for the six months ended June 30, 2017 and 2016 in conformity with accounting principles generally accepted in the United States.
