Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	NOTE 2. RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. The objective of this guidance is to establish the principles for reporting useful information to users of financial statements about the nature, timing and uncertainty of revenue from contracts with customers. The FASB has continued to issue ASUs to clarify and provide implementation guidance related to Revenue from Contracts with Customers, including ASU 2016-08, Revenue from Contract with Customers: Principal versus Agent Considerations, ASU 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing, ASU 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients and ASU 2016-20, Revenue from Contracts with Customers: Technical Correction and Improvements. These amendments address a number of areas, including the entity’s identification of its performance obligations in a contract, collectability, non-cash consideration, presentation of sales tax and an entity’s evaluation of the nature of its promise to grant a license of intellectual property and whether or not that revenue is recognized over time or at a point in time. These standards are effective for the interim and annual reporting periods beginning after December 31, 2017. The new standard permits two methods of adoption: retrospectively to each prior period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). While the Company is still evaluating the potential impact of this guidance, including the method of adoption, the Company believes the majority of its revenue, as such revenue relates to rental contractual revenue, is excluded from the scope of this standard, and the remaining revenue streams will not be materially affected. The Company’s Enviroplex division currently recognizes the sale of its manufactured modular buildings to customers following the completed contract method which, under the new guidance, may change to occur over time. The Company currently does not anticipate the adoption of this guidance will have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Subtopic 842-10). Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) on 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 b) 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. The amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. While the Company is still evaluating the potential impact of this guidance, as a lessor, the Company does not believe the accounting for operating lease revenues will be materially affected by this standard. The Company anticipates its lessee accounting to increase its total assets and liabilities; however, the Company is currently evaluating the magnitude of the impact the adoption of this guidance will have on the Company’s consolidated financial statements. During the first quarter 2017, the Company adopted ASU No. 2016-09 Improvements to Employee Share-Based Payment Accounting (ASU 2016-09). As a result of the adoption, the Company recognized $116,000 and $134,000 of excess tax benefits related to share-based payments as a reduction to the provision for income taxes for the three and six months ended June 30, 2017, respectively. These tax benefits, or shortfalls, were historically recorded in equity. In addition, cash flows related to excess tax benefits, or shortfalls, are now classified as an operating activity with the prior period adjusted accordingly. Cash paid on employees’ behalf related to shares withheld for tax purposes is classified as a financing activity, consistent with prior year’s presentation. Retrospective application of the cash flow presentation requirements resulted in decreases to both net cash provided by operations and net cash used in financing activities of $871,000 for the six months ended June 30, 2016. The Company’s compensation expense for each period continues to reflect forfeitures as they occur, rather than based upon estimated expected forfeitures. In May 2017, the FASB issued ASU No. 2017-09, Compensation, Stock Compensation (Topic 718). The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all of the following are met: 1) the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; 2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified and; 3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments of this update are effective for the interim and annual periods beginning after December 15, 2017. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
