RSUs containing service conditions vest monthly or annually. RSUs containing performance conditions generally vest over 1 year, and the number of shares earned depends on the achievement of

predetermined Company metrics. RSUs that contain market conditions will vest based on the terms of the agreement and generally are over the employee's term of employment.

The expense is recognized ratably over the requisite service period.
