Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-03. The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company adopted the guidance on January 1, 2016 and as a result, debt issuance costs of $22,275 were reclassified from "Other assets" to "Long-term debt" on the Company's condensed consolidated balance sheet as of December 31, 2015. In April 2015, the FASB issued ASU No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement ("ASU No. 2015-05"). This guidance is intended to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement, primarily to determine whether the arrangement includes a sale or license of software. ASU No. 2015-05 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. The Company adopted the guidance during the three months ended March 31, 2016. The adoption of ASU No. 2015-05 did not have a material impact on the Company's condensed consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU No. 2016-01”). The amendments in this update require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon occurrence of an observable price change or upon identification of an impairment. The amendments in ASU No. 2016-01 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For amendments applicable to the Company, early adoption is not permitted. The Company will conform to ASC No. 2016-01 in the condensed consolidated financial statements in future periods. In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU No. 2016-02"). This ASU amends the existing accounting considerations and treatments for leases through the creation of Topic 842, Leases, to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosing key information about lease arrangements. The amendments in ASU No. 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments is permitted for all entities. The Company has decided not to early adopt ASU No. 2016-02 and is currently evaluating the impact the amendments may have on its condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, Equity Method and Joint Ventures (“ASU No. 2016-07”). The amendments in the update eliminate the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of account as of the date the investment becomes qualified for equity method accounting. The amendments in ASU No. 2016-07 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company has not elected to early adopt. The adoption of ASU No. 2016-07 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, Principal Versus Agent Considerations (“ASU No. 2016-08”). The amendments to this update are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. The amendments in ASU No. 2016-08 are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating ASU No. 2016-08 and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU No. 2016-09”). The objective of this update is to simplify several aspects of the accounting for 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 No. 2016-09 are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company has not elected to early adopt. The Company is currently evaluating ASU No. 2016-09 and has not determined the impact this amendment may have on its financial statements. In April 2016, the FASB issued ASU No. 2016-10, Identifying Performance Obligations and Licensing (“ASU No. 2016-10”). The amendments in this update clarify the following two aspects of Accounting Standards Codification ("ASC") 606, Revenue From Contracts With Customers: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The amendments in ASU No. 2016-10 are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating ASU No. 2016-10 and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption.
Investments	In addition to the available-for-sale securities above, the Company has equity investments in non-public companies in which the Company acquired non-controlling interests and for which no readily determinable market value exists. These securities were accounted for under the cost method in accordance with ASC 323-10-25, The Equity Method of Accounting for Investments in Common Stock.
Disclosures about Segments of an Enterprise and Related Information	ASC 280-10, Disclosures About Segments of an Enterprise and Related Information (“ASC 280-10”), establishes standards for reporting information about operating segments. ASC 280-10 requires that a public business enterprise reports financial and descriptive information about its operating segments.
Related Party Disclosures	The Company considers its stockholders that own more than 5.0% of the outstanding common stock to be related parties as defined within ASC 850, Related Party Disclosures. As of March 31, 2016 and December 31, 2015, the Company had no transactions with related parties owning more than 5.0% of its common stock, except for transactions with the KSOP as disclosed in Note 16 Compensation Plans of the Company's consolidated financial statements included in the 2015 Form 10-K filing.

Disclosure of accounting policy for investments in financial assets, including marketable securities (debt and equity securities with readily determinable fair values), investments accounted for under the equity method and cost method, securities borrowed and loaned, and repurchase and resale agreements. For marketable securities, the disclosure may include the entity's accounting treatment for transfers between investment categories and how the fair values for such securities are determined. Also, for all investments, an entity may describe its policy for assessing, recognizing and measuring impairment of the investment.
