Recently Issued Accounting Standards [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Recently Issued Accounting Standards In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers. The standard’s core principle is that a company will recognize revenue when it transfers 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. This standard also includes expanded disclosure requirements that result in an entity providing users of financial statements with comprehensive information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from the entity’s contracts with customers. In August 2015, ASU 2015-14 was issued deferring the effective date of ASU 2014-09 to annual reporting periods beginning after December 15, 2017 with an optional early application date for annual reporting periods beginning after December 15, 2016. The Company will adopt the standard and all subsequent amendments in the first quarter of the fiscal year ending December 31, 2018. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). We currently anticipate adopting the standard using the full retrospective method to restate each prior reporting period presented. Our ability to adopt using the full retrospective method is dependent on the successful and timely implementation of a revenue software application that has been procured from a third-party provider and the completion of our analysis of information necessary to restate prior period financial statements. While we are continuing to assess all potential impacts of the standard, we currently believe the standard will not have a material impact on our consolidated financial statements with the possible exception of our gross treatment of hardware revenue. ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations and was not intended to change the historical presentation of value added resellers as gross, however there appears to be diversity in opinion based on facts and circumstances. We will continue to monitor discussions by the Transition Resource Group and the FASB throughout 2017. The FASB issued ASU 2014-15, Disclosure of Uncertainties About an Entity's Ability to Continue as a Going Concern in August 2014. This standard update provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The standard is effective for us for the fiscal year ending December 31, 2016. The adoption of this pronouncement did not have a material impact on our financial statements. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which changes the presentation of debt issuance costs in the financial statements. Specifically, this amendment requires that costs associated with the issuance of debt be presented on the balance sheet as a direct deduction from the related debt liability. The Company retrospectively adopted the amended standard effective January 1, 2016. The adoption resulted in a prior period adjustment due to a change in accounting principle. The Consolidated Balance Sheet for the period ending December 31, 2015 has been restated to reflect this change in accounting principle. Note issuance costs of $8.0 million were reclassed from “Other noncurrent assets” to “Long-term debt, less current portion.” On the effective date of ASU 2015-03, the Company made a one-time policy election to record costs incurred in connection with obtaining revolving credit agreements as an asset and to amortize these costs ratably over the term of the agreement. This accounting treatment is consistent with how deferred financing costs were accounted for prior to adoption of ASU 2015-03. Note 6 has been updated to reflect the adjustment. The FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which amends the guidance in GAAP on the classification and measurement of financial instruments in January 2016. The amended guidance requires entities to carry all investments in equity securities at fair value through net income unless the entity has elected the practicability exception to fair value measurement. This standard will be effective for the fiscal year ending December 31, 2018 and will require a cumulative-effect adjustment to beginning retained earnings on this date. The Company is currently in the process of evaluating the impact of adoption of this ASU on the consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases, which represents a wholesale change to lease accounting. The standard introduces a lessee model that brings most leases on the balance sheet as well as aligns certain underlying principles of the new lessor model with those in ASC 606. The new standard is effective for public entities for fiscal years beginning after December 15, 2018, and lessees and lessors are required to use a modified retrospective transition method for existing leases. The Company is in the process of evaluating the impact of adoption of this ASU on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation, which simplifies various aspects related to how share-based payments are accounted for and presented in the financial statements. The new guidance requires excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled. In addition, cash flows related to excess tax benefits will no longer be separately classified as a financing activity apart from other income tax cash flows. The standard also allows us to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting, clarifies that all cash payments made on an employee’s behalf for withheld shares should be presented as a financing activity on our cash flows statement, and provides an accounting policy election to account for forfeitures as they occur. The new standard is effective for us beginning January 1, 2017. The primary impact of adoption will be the recognition of excess tax benefits in our provision for income taxes rather than paid-in capital starting in the first quarter of fiscal year 2017. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements will have no impact to retained earnings at January 1, 2017, where the cumulative effect of these changes are required to be recorded. We have elected to adopt a company-wide policy change due to the change in accounting principle and will record forfeitures as they are incurred on a go forward basis. As a result of the change in accounting principle the cumulative-effect adjustment to retained earnings to account for the accounting policy election is immaterial to the financial statements. We plan to apply the presentation requirements for cash flows related to excess tax benefits retrospectively to all periods presented which is not expected to have a material impact to 2016 net cash provided by operations and 2016 net cash used in financing when presented in 2017. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented in our consolidated cash flows statements since such cash flows have historically been presented as a financing activity. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flow - Classification of Certain Cash Receipts and Cash Payments, which amends ASC 230 to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. The FASB issued the ASU with the intent of reducing diversity in practice. The new standard is effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently in the process of evaluating the impact of adoption of this ASU on the Company’s consolidated statement of cash flows and plans to adopt the standard effective January 1, 2018. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates Step 2 from the goodwill impairment test. Under the amended guidance, the Company shall now recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit's fair value. The new standard is effective for public entities for annual reporting periods beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company plans to early adopt the amended guidance effective January 1, 2017 and does not anticipate a significant impact to the financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s consolidated financial statements upon adoption.
