Stock-based compensation expense for all share-based payment awards to employees who provide services to the Company is based on the estimated grant-date fair value. The Company recognizes these compensation costs net of an estimated forfeiture rate for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the award vesting term. For ratable awards, the Company recognizes compensation costs for all grants on a straight-line basis over the requisite service period of the entire award.
Assets Held for Sale
The Company records assets held for sale at the lower of the carrying value or fair value less costs to sell. The following criteria are used to determine if property is held for sale: (i) management has the authority and commits to a plan to sell the property; (ii) the property is available for immediate sale in its present condition; (iii) there is an active program to locate a buyer and the plan to sell the property has been initiated; (iv) the sale of the property is probable within one year; (v) the property is being actively marketed at a reasonable price relative to its current fair value; and (vi) it is unlikely that the plan to sell will be withdrawn or that significant changes to the plan will be made.
In determining the fair value of the assets less costs to sell, the Company considers factors including current sales prices for comparable assets in the region, recent market analysis studies, appraisals and any recent legitimate offers. If the estimated fair value less costs to sell of an asset is less than its current carrying value, the asset is written down to its estimated fair value less costs to sell. Due to uncertainties in the estimation process, it is reasonably possible that actual results could differ from the estimates used in the Company's historical analysis. The Company's assumptions about project sale prices require significant judgment because the current market is highly sensitive to changes in economic conditions. The Company estimates the fair values of assets held for sale based on current market conditions and assumptions made by management, which may differ from actual results and may result in additional impairments if market conditions deteriorate.
When assets are classified as held for sale, the Company does not record depreciation or amortization for the respective renewable energy facilities or intangibles.
Recent Accounting Developments
In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU No. 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how to apply the implementation guidance on principal versus agent considerations related to the sale of goods or services to a customer as updated by ASU No. 2014-09. ASU No. 2014-09 and ASU No. 2016-08 will become effective for the Company on January 1, 2018. Early application is permitted but not before January 1, 2017. ASU No. 2014-09 and ASU No. 2016-08 permit the use of either the retrospective or modified retrospective method. The Company is working through an adoption plan which includes the evaluation of revenue contracts compared to the new standards and evaluating the impact of the new standards on the Company's consolidated financial statements and related disclosures. The Company does not plan to adopt these standards prior to January 1, 2018.
In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires an entity’s management to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern and to provide related footnote disclosures. ASU No. 2014-15 is effective for interim and annual periods ending after December 15, 2016, with early adoption permitted for interim and annual reporting periods for which the financial statements have not been previously issued. The adoption of ASU No. 2014-15 on December 31, 2016 had no impact on the Company's consolidated financial statements, only the related disclosures. Refer to Note 1. Nature of Operations and Basis of Presentation for disclosures regarding management's evaluation of whether there is substantial doubt about the Company's ability to continue as a going concern.
In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810) Amendments to the Consolidation Analysis, which affects the following areas of the consolidation analysis: limited partnerships and similar entities, evaluation of
