Accounting Policies [Abstract]
Recent Accounting Standards	Recent Accounting Standards In August 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The new standard is designed to refine and expand hedge accounting for both financial (e.g., interest rate) and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also makes certain targeted improvements to simplify the application of hedge accounting guidance. The new standard is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption, including adoption in an interim period, is permitted. If early adoption is elected in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period (i.e., the initial application date). The Company is currently evaluating the impact this ASU will have on its consolidated condensed financial statements and disclosures. In March 2016, the FASB issued ASU No. 2016-09, "Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." This amendment is intended to simplify several aspects of the accounting for share-based payment transactions, including (i) the recognition of excess tax benefits or deficiencies in the operating statement when compensatory stock awards are vested and settled, and the presentation of these tax benefits or deficiencies as an operating cash outflow on the statement of cash flows, (ii) the option to withhold the maximum statutory tax rate on the settlement of compensatory stock without triggering liability accounting, as well as presenting the shares withheld for the settlement of these taxes as a financing outflow on the statement of cash flows, and (iii) the option to elect a change in the accounting policy to account for forfeitures as they occur. This amendment became effective for the Company as of January 1, 2017. The Company adopted this ASU using the modified retrospective transition method with respect to the recognition of excess tax benefits in the consolidated condensed statement of operations. The adoption did not result in a cumulative-effect adjustment to equity as of January 1, 2017. The amendment related to the cash flow presentation of shares acquired to satisfy the Company's minimum tax withholding requirements in connection with the settlement of compensatory stock was applied retrospectively as a financing outflow. The adoption had no impact to any periods presented on the consolidated condensed statement of cash flows as these cash outflows have historically been presented as a financing activity. The Company elected not to change its accounting policy on the recognition of estimated forfeitures. In March 2016, the FASB issued ASU No. 2016-04, "Liabilities—Extinguishment of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products." The amendment clarifies when it is acceptable to recognize the unredeemed portion of prepaid gift cards into income, and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. As of September 30, 2017, the Company had $1,050,000 of deferred revenue related to unredeemed gift cards. The Company does not expect the adoption of this ASU will have a material impact on its consolidated condensed financial statements and disclosures. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) 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. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply 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. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently evaluating the impact this ASU will have on its consolidated condensed financial statements and disclosures. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments─Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendment requires (i) equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, (ii) public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and (iii) separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). This amendment eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost. This amendment is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. As of September 30, 2017, the Company had an investment in Topgolf International, Inc. of $50,495,000 that was accounted for at cost in accordance with ASC Topic 325, “Investments—Other” (see Note 8). Based on prior observable market transactions, the Company believes that the fair value of its investment in Topgolf significantly exceeds its cost. However, the Company is currently unable to estimate the fair value of this investment as of September 30, 2017, as it was not practical to do so, and there were no recent identifiable events or changes in circumstances that had a significant effect on fair value. If there are any observable price changes related to this investment or a similar investment of the same issuer in fiscal years beginning after December 15, 2017, the Company would be required to write this investment up or down to its estimated fair value, which could have a significant effect on the Company's financial position and results of operations. In July 2015, the FASB issued ASU No. 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory." This amendment requires an entity to measure in-scope inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. For public business entities, this ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of this amendment did not have a material impact on the Company's consolidated condensed financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers: (Topic 606)." This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosures regarding revenue and contracts with customers.
