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. 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. 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.

In November 2014, the FASB issued ASU 2014-16, “Derivatives and Hedging (Topic 815).” ASU 2014-16 addresses whether the host contract in a hybrid financial instrument issued in the form of a share should be accounted for as debt or equity. ASU 2014-16 is effective for annual periods and interim periods beginning after December 15, 2015. We do not currently have issued, nor are we investors in, hybrid financial instruments. Accordingly, we do not expect the adoption of ASU 2014-16 to have any effect on our financial position, results of operations or cash flows.
