The requirements of ASU 2014-16 are effective for reporting periods beginning after December 15, 2015, with early adoption permitted. The effects of initially adopting ASU 2014-16 should be applied on a modified retrospective basis to existing hybrid financial instruments issued in the form of a share as of the beginning of the fiscal year for which the amendments are effective. Retrospective application is permitted to all relevant prior periods.
