In determining the fair value of certificates of deposit, a discounted cash flow analysis was used, which involved present valuing the contractual payments over the remaining life of the certificates of deposit at market-based interest rates. Third-party acquisition related expenses are recognized as incurred and continue until the acquired system is converted and operational functions become fully integrated.
