Risks and Uncertainties [Abstract] |
Concentrations of Credit Risk | Concentrations of Credit RiskConcentration of credit risk is the risk associated with a lack of diversification, such as having substantial investments in a few individual issuers, thereby exposing us to greater risks resulting from adverse economic, political, regulatory, geographic, industrial or credit developments. Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investment securities and loans. Our cash in correspondent bank accounts, at times, may exceed FDIC insured limits. We place cash and cash equivalents with the Federal Reserve Bank and other high credit quality financial institutions, periodically monitor their credit worthiness and limit the amount of credit exposure to any one institution according to regulations. Concentrations of credit risk with respect to investment securities primarily related to the U.S. government and GSEs, which accounted for $1.277 billion, or 85% of our total investment portfolio at December 31, 2021 and $389.1 million, or 78% at December 31, 2020. The increase is due to both the acquired ARB investment security portfolio, including U.S. government and GSEs totaling $261.3 million at the date of acquisition, as well as the deployment of excess liquidity throughout 2021 into securities with purchases of $827.9 million in this security type. Our largest investment security issued by a non-GSE issuer accounted for approximately 2% of our total investment portfolio at December 31, 2021, and 3% at December 31, 2020. We also manage our credit exposure related to our loan portfolio to avoid the risk of undue concentration of credits in a particular industry by reducing significant exposure to highly leveraged transactions or to any individual customer or counterparty, and by obtaining collateral as appropriate. No single borrower relationship accounts for more than 3% of outstanding loan balances at December 31, 2021 or 2020. The largest loan concentration group by industry of the borrowers is real estate, which accounted for 84% and 76% of our loan portfolio at December 31, 2021 and 2020, respectively. The increase in the percentage in real estate from 2020 to 2021 was primarily due to a $180.4 million reduction in unsecured loans guaranteed by the SBA under the Paycheck Protection Program ("PPP"), which are included in commercial and industrial loans.
