ASU 2014-12 indicates that, in such situations, the performance target should be treated as a performance condition and, accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award.

Note 13. Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued accounting standards update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” which amends the accounting guidance related to revenues. This amendment will replace most of the existing revenue recognition guidance when it becomes effective. The new standard, as amended in July 2015, is effective for fiscal years beginning after December 15, 2017 and entities are allowed to adopt the standard as early as annual periods beginning after December 15, 2016, and interim periods therein. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect this amendment will have on our consolidated financial statements and related disclosures and believe the financial impact is not material. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

In June 2014, the FASB issued ASU 2014-12, “Compensation – Stock Compensation (Topic 718).” ASU 2014-12 addresses accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period.

Instead, compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015.
