December 31, 2020, we recorded $0, $0 and $22,000, respectively, in charges to the ACL in connection with loans transferred to other real estate owned. For the three and six months ended June 30, 2021 and the twelve months ended December 31, 2020, we recorded $1,915,000, $2,065,000 and $1,539,000, respectively, in adjustments to fair value in connection with other real estate owned.
The fair value estimates, methods, and assumptions for our financial instruments at June 30, 2021 and December 31, 2020 are outlined below.
Cash and Cash Equivalents
For these short-term instruments, the carrying amount is a reasonable estimate of fair value.
Time Deposits with Banks
The carrying amounts of time deposits with banks approximate fair value.
Investment Securities Held-to-Maturity
The carrying amounts of investments held-to-maturity approximate fair value.
Investment Securities
For investment securities, which include U.S. Treasury securities, obligations of other U.S. government agencies, obligations of states and political subdivisions and mortgage pass-through and related securities, fair values are from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. See disclosures of fair value of investment securities in Note 6.
Loans
Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as commercial, real estate and consumer loans, as outlined by regulatory reporting guidelines. Each category is segmented into fixed and variable interest rate terms and by performing and non-performing categories.
For variable rate performing loans, the carrying amount approximates the fair value. For fixed-rate performing loans, except residential mortgage loans, the fair value is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. For performing residential mortgage loans, fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using discount rates based on secondary market sources or the primary origination market. Fixed-rate performing loans are within Level 3 of the fair value hierarchy. At June 30, 2021 and December 31, 2020, the carrying amount of fixed rate performing loans was $1,664,177,000 and $1,812,413,000, respectively, and the estimated fair value was $1,610,401,000 and $1,747,257,000, respectively.
Accrued Interest
The carrying amounts of accrued interest approximate fair value.
Deposits
The fair value of deposits with no stated maturity, such as non-interest bearing demand deposit accounts, savings accounts and interest bearing demand deposit accounts, was equal to the amount payable on demand as of June 30, 2021 and December 31, 2020. The fair value of time deposits is based on the discounted value of contractual cashflows. The discount rate is based on currently offered rates. Time deposits are within Level 3 of the fair value
