Securities (Details) [Line Items] |  |
Securities, Description | Securities available for sale consist of U.S. government agency securities and mortgage-backed securities guaranteed by U.S. government agencies. Securities held to maturity consist of Property Assessed Clean Energy (“PACE”) and Public Improvement District/Tax Increment Reinvestment Zone (“PID/TIRZ”) investments. These investment contracts or bonds located in Texas, California and Florida, originate under a contractual obligation between the property owners, the local county or city administration, and a third-party administrator and sponsor. PACE assessments are created to fund the purchase and installation of energy saving improvements to the property such as solar panels. PID/TIRZ assessments are used to pay for the development costs of a residential subdivision. Generally, as a property assessment, the total assessment is repaid in installments over a period of 5 to 32 years by the then current property owner(s). Each installment is collected by the County or City Tax Collector where the property is located. The assessments are an obligation of the property. Securities, restricted consist of Federal Reserve Bank of Dallas (“FRB”) and Federal Home Loan Bank of Dallas (“FHLB”) stock, which are carried at cost. |
