Summary of Significant Accounting Policies [Abstract]
Significant Accounting Policies	Summary of Significant Accounting Policies The significant accounting policies used in the preparation of the Company's condensed consolidated financial statements are disclosed in the 2016 Form 10-K, other than certain recent accounting pronouncements described below. Recently Adopted Accounting Pronouncements No accounting pronouncements adopted during the nine months ended September 30, 2017 had a material impact on the Company's condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In May 2014, the FASB released updated guidance regarding the recognition of revenue from contracts with customers, exclusive of those contracts within lease accounting. 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. To achieve that core principle, an entity should apply the following steps: (1) identify the contracts with the customer; (2) identify the performance obligations in the contract; (3) determine the contract price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. This guidance is effective for the Company on January 1, 2018, following the FASB's July 2015 decision to defer the effective date of the standard by one year. This guidance is required to be applied, at the Company's election, either (1) retrospectively to each prior reporting period presented, or (2) with the cumulative effect being recognized at the date of initial application. The Company expects to adopt the guidance effective January 1, 2018 with the cumulative effect being recognized at the date of initial application, and does not expect the guidance to have a material impact on its condensed consolidated financial statements. In February 2016, the FASB issued new guidance on the recognition, measurement, presentation and disclosure of leases. The new guidance requires lessees to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments for all leases with a term greater than 12 months. The accounting for lessors remains largely unchanged from existing guidance. This guidance is effective for the Company as of January 1, 2019 and is required to be applied using a modified retrospective approach for all leases existing at, or entered into after, the beginning of the earliest comparative period presented. Early adoption is permitted, however, the Company does not expect to early adopt the new guidance. The Company (1) has established and is progressing through the various steps of a cross functional project plan to assess the impact of the standard; (2) expects this guidance to have a material impact on its condensed consolidated balance sheet due to the addition of right-of-use assets and lease liabilities for all lessee arrangements with a term greater than 12 months; and (3) continues to assess additional impacts to its condensed consolidated financial statements, including the condensed consolidated statement of operations and the condensed consolidated statement of cash flows. In February 2017, the FASB issued new guidance which clarifies the scope and application on accounting for the de-recognition of non-financial assets and in substance non-financial assets, including sales and partial sales of real estate assets. The new guidance also eliminates the existing industry specific guidance for partial sales of real estate, and requires full gain recognition upon partial sales of real estate. The guidance is effective for the Company as of January 1, 2018. The guidance may be early adopted, but must be adopted concurrently with the FASB's May 2014 guidance on revenue from contracts with customers. The guidance is required to be applied, at the Company's election, either (1) retrospectively to each prior reporting period presented or (2) with the cumulative effect being recognized at the date of initial application. The Company does not expect this guidance to have a material impact on its condensed consolidated financial statements.
