(a) Certificates of deposit held for investment with an original maturity greater than three months are carried at original cost plus accrued interest and reported as other assets on the condensed consolidated balance sheets. The type of certificates of deposit that the Company invests in are not considered debt securities under ASC Topic 320, Investments - Debt Securities. The estimated fair value of our certificates of deposit has been determined using quoted market rates (Level 2).

(b) Carrying amounts for financial liabilities are net of unamortized debt issuance costs or accretion.

(c) The estimated fair value of our publicly-held Senior Notes has been determined using quoted market rates (Level 2).

(d) Since there is no trading market for our Junior Subordinated Notes, the fair value of these notes is estimated by discounting scheduled cash flows through maturity (Level 3). The discount rate is estimated using market rates currently being offered on loans with similar terms and credit quality. Judgment is required in interpreting market data to develop these estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize in a current market exchange.
