The US Financial Accounting Standards Board (FASB) has agreed to delay issuance of an exposure draft on stock-based compensation until the first quarter of 2004, with the goal of issuing the final Statement in the second half of 2004. The FASB also showed a preference towards using the binomial model rather than the Black-Scholes model to measure the fair value of employee share options, as the former is better able to take into account factors such as performance conditions as well as vesting and holding periods, compared to the latter.

The IASB's ED 2, Share-Based Payment would not prescribe any particular model. Its current timetable calls for issuing a final IFRS in the first quarter of 2004.
