1. Statement of Financial Accounting Standard No. 155 Accounting for Certain Hybrid Financial Instruments - an amendment of FASB Statements No. 133 and 140 (SFAS No. 155)
In February 2006, the FASB issued SFAS No. 155, which amends Statements No. 133 and 140. This Statement:
This Statement is effective for all financial instruments acquired or issued after the beginning of an entitys first fiscal year that begins after September 15, 2006. The fair value election provided for in paragraph 4(c) of this Statement may also be applied upon adoption of this Statement for hybrid financial instruments that had been bifurcated under paragraph 12 of Statement 133 prior to the adoption of this Statement. Earlier adoption is permitted. Provisions of this Statement may be applied to instruments that an entity holds at the date of adoption on an instrument-by-instrument basis.
At adoption, any difference between the total carrying amount of the individual components of the existing bifurcated hybrid financial instrument and the fair value of the combined hybrid financial instrument should be recognized as a cumulative-effect adjustment to beginning retained earnings. An entity should separately disclose the gross gains and losses that make up the cumulative-effect adjustment, determined on an instrument-by-instrument basis. Prior periods should not be restated.
The Companys management has not assessed the potential impact of this standard on its financial statements.
