Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, which is designed to clarify the principles used to recognize revenue for entities. The core principle of ASU 2014-09 is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In addition, ASU 2014-09 requires enhanced disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. While ASU 2014-09 is primarily associated with guidance for revenue from contracts with customers, it also includes new accounting principles related to deferral and amortization of contract acquisition and fulfillment costs. In 2016, the Company performed an assessment of its revenues, acquisition and fulfillment costs from contracts to understand any potential differences to its current accounting policies and business processes. The Company expects it to have an impact concerning the deferral of acquisition costs as its current policy is to expense these costs as incurred. At this time, the Company continues to assess and determine data and system requirements necessary to quantify the impacts of this standard as well as to develop and provide the enhanced disclosures required by the new guidance. In July 2015, the FASB approved a one-year deferral of the effective date of ASU 2014-09. Subsequently, the FASB has issued several additional ASUs to clarify the implementation guidance on principal versus agent considerations, identifying performance obligations, assessing collectability, presentation of sales taxes and other similar taxes collected from customers, non-cash considerations, contract modifications and completed contracts at transition. The new pronouncements will be effective for annual and interim periods beginning on or after December 15, 2017. The Company intends to adopt the new standard effective January 1, 2018. The standard allows for two methods of adoption: (1) "full retrospective" adoption, meaning the standard is applied to all periods presented, or (2) "modified retrospective" adoption, meaning the cumulative effect of applying ASU 2014-09 is recognized as an adjustment to the fiscal year 2018 opening retained earnings balance. Currently, the Company is evaluating the available adoption methods and the Company plans to select an adoption method in the second half of 2017. In February 2016, the FASB issued ASU 2016-02, Leases, whereby, lessees will be required to recognize for all leases at the commencement date a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and 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. Under the new guidance, lessor accounting is largely unchanged. A modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements must be applied. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Companies may not apply a full retrospective transition approach. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018. Early application is permitted. Currently, the Company is evaluating the potential impact of this pronouncement. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment award transactions, including, but not limited to: (a) income tax consequences; (b) classification of awards as either equity or liabilities; and (c) classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016. The Company adopted this pronouncement effective January 1, 2017 and recorded a cumulative-effect adjustment to retained earnings of $0.1 million as the result of the change in accounting policy to recognize forfeitures as they occur. In addition, the Company reclassified "Repurchases of common stock to satisfy tax withholding obligations" from "Accounts payable and accrued liabilities" in the condensed consolidated statement of cash flows for the three months ended March 31, 2016 to be consistent with current period presentation. The deferred tax asset for NOL carryforwards from share-based compensation was fully offset by a corresponding valuation allowance and resulted in no adjustment for income taxes. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash, which requires a statement of cash flows to explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, and early adoption is permitted, including in an interim period. If early adopted in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. ASU 2016-18 is to be applied through a retrospective transition method to each period presented. The Company currently intends to adopt ASU 2016-18 effective January 1, 2018 and does not believe it will have a significant impact on its consolidated statements of cash flows. In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which requires employers to present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost, including interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects, are to be presented outside of any subtotal of operating income. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. ASU 2017-07 is effective for fiscal years and interim periods beginning after December 15, 2017, and early adoption is permitted. The Company currently intends to adopt ASU 2017-07 effective January 1, 2018 and does not expect it will have a material impact on its consolidated financial statements.
