PMBC is registered as a one bank holding company under the United States Bank Holding Company Act of 1956, as amended. The Bank is chartered by the California Department of Financial Institutions (the “DFI”) and is a member of the Federal Reserve Bank of San Francisco (“FRB”). In addition, the deposit accounts of the Bank’s customers are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to the maximum amount allowed by law. PMBC and the Bank are sometimes referred to, together, in this report as the “Company” or as “we”, “us” or “our”.

Substantially all of our operations are conducted and substantially all our assets are owned by the Bank, which accounts for substantially all of our consolidated revenues and expenses, and our earnings. The Bank provides a full range of banking services to small and medium-size businesses, professionals and the general public in Orange, Los Angeles, San Bernardino and San Diego Counties of California and is subject to competition from other banks and financial institutions and from financial services organizations conducting operations in those same markets.

During 2002, we organized three business trusts, under the names Pacific Mercantile Capital Trust I, PMB Capital Trust I, and PMB Statutory Trust III, respectively, to facilitate our issuance of $5.155 million, $5.155 million and $7.217 million, respectively, principal amount of junior subordinated debentures, all with maturity dates in 2032. In October 2004, we organized PMB Capital Trust III to facilitate our issuance of an additional $10.310 million principal amount of junior subordinated debentures, with a maturity date in 2034. In accordance with applicable accounting standards, the financial statements of these trusts are not included in the Company’s consolidated financial statements. See Note 2: “Significant Accounting Policies — Principles of Consolidation” in the Notes to Consolidated Financial Statements included in the Company’s Form 10-K for the year ended December 31, 2011.

In July 2007, we redeemed the $5.155 million principal amount of junior subordinated debentures issued in conjunction with the organization of Pacific Mercantile Capital Trust I and in August 2007, we redeemed the $5.155 million principal amount of junior subordinated debentures issued in conjunction with the organization of PMB Capital Trust I. Those trusts were dissolved as a result of those redemptions.
