Our agricultural mortgage loan portfolio consists of loans with an outstanding principal balance of $567.6 million and $408.1 million as of December 31, 2022 and 2021, respectively. These loans are collateralized by agricultural land and are diversified as to location within the United States. Our residential mortgage loan portfolio consists of loans with an outstanding principal balance of $2.8 billion and $1.7 billion as of December 31, 2022 and 2021, respectively. These loans are collateralized by the related properties and diversified as to location within the United States.

Mortgage loans on real estate are generally reported at cost adjusted for amortization of premiums and accrual of discounts, computed using the interest method and net of valuation allowances. Interest income is accrued on the principal amount of the loan based on the loan's contractual interest rate. Interest income is included in Net investment income on our Consolidated Statements of Operations. Accrued interest receivable, which was $58.2 million and $37.0 million as of December 31, 2022 and 2021, respectively, is included in Accrued investment income on our consolidated balance sheets.

Loan Valuation Allowance

We establish a valuation allowance to provide for the risk of credit losses inherent in our mortgage loan portfolios. The valuation allowance is maintained at a level believed adequate by management to absorb estimated expected credit losses. The valuation allowance is based on amortized cost, which excludes accrued interest receivable. We do not measure a credit loss allowance on accrued interest receivable as we write off any uncollectible accrued interest receivable balances to net investment income in a timely manner. We did not charge off any uncollectible accrued interest receivable on our commercial, agricultural or residential mortgage loan portfolios for the years ended December 31, 2022 or 2021, respectively.

The valuation allowances for each of our mortgage loan portfolios are estimated by deriving probability of default and recovery rate assumptions based on the characteristics of the loans in each portfolio, historical economic data and loss information, and current and forecasted economic conditions. Key loan characteristics impacting the estimate for our commercial mortgage loan portfolio include the current state of the borrower’s credit quality, which considers factors such as loan-to-value (“LTV”) and debt service coverage (“DSC”) ratios, loan performance, underlying collateral type, delinquency status, time to maturity, and original credit scores. Key loan characteristics impacting the estimate for our agricultural and residential mortgage loan portfolios include the current state of the borrowers' credit quality, delinquency status, time to maturity and original credit scores.

The following table represents a rollforward of the valuation allowance on our mortgage loan portfolios:

Charge-offs include allowances that have been established on loans that were satisfied either by taking ownership of the collateral or by some other means such as discounted pay-off or loan sale. When ownership of the property is taken it is recorded at the lower of the loan's carrying value or the property's fair value (based on appraised values) less estimated costs to sell. The real estate owned is recorded as a component of Real estate investments and the loan is recorded as fully paid, with any allowance for credit loss that has been established charged off. Fair value of the real estate is determined by third party appraisal. There is no real estate in which ownership of the property was taken to satisfy an outstanding loan held in Real estate investments as of December 31, 2022 or December 31, 2021. Recoveries are situations where we have received a payment from the borrower in an amount greater than the carrying value of the loan (principal outstanding less specific allowance).

Credit Quality Indicators

We evaluate the credit quality of our commercial and agricultural mortgage loans by analyzing LTV and DSC ratios and loan performance. We evaluate the credit quality of our residential mortgage loans by analyzing loan performance.

LTV and DSC ratios for our commercial mortgage loans are originally calculated at the time of loan origination and are updated annually for each loan using information such as rent rolls, assessment of lease maturity dates and property operating statements, which are reviewed in the context of current leasing and in place rents compared to market leasing and market rents. A DSC ratio of less than 1.0 indicates that a property's operations do not generate sufficient income to cover debt payments. An LTV ratio in excess of 100% indicates the unpaid loan amount exceeds the value of the underlying collateral. All of our commercial mortgage loans that have a debt service coverage ratio of less than 1.0 are performing under the original contractual loan terms at December 31, 2022 and 2021.

The amortized cost of our commercial mortgage loan portfolio by LTV and DSC ratios based on the most recent information collected was as follows at December 31, 2022 and 2021 (by year of origination):

LTV and DSC ratios for our agricultural mortgage loans are calculated at the time of loan origination and are evaluated annually for each loan using land value averages. A DSC ratio of less than 1.0 indicates that a property's operations do not generate sufficient income to cover debt payments. An LTV ratio in excess of 100% indicates the unpaid loan amount exceeds the value of the underlying collateral. All of our agricultural mortgage loans that have a debt service coverage ratio of less than 1.0 are performing under the original contractual loan terms at December 31, 2022 and 2021.

The amortized cost of our agricultural mortgage loan portfolio by LTV and DSC ratios based on the most recent information collected was as follows at December 31, 2022 and 2021 (by year of origination):

Commercial, agricultural and residential mortgage loans are considered nonperforming when they become 90 days or more past due. When loans become nonperforming, we place them on non-accrual status and discontinue recognizing interest income. If payments are received on a nonperforming loan, interest income is recognized to the extent it would have been recognized if normal principal and interest would have been received timely. If payments are received to bring a nonperforming loan back to less than 90 days past due, we will resume accruing interest income on that loan. There were 59 loans in non-accrual status at December 31, 2022 and 13 loans in non-accrual status at December 31, 2021. During the years ended December 31, 2022 and 2021, we recognized interest income of $670 thousand and $36 thousand, respectively, on loans which were in non-accrual status at the respective period end. During the year ended December 31, 2020 we recognized no interest income on loans which were in non-accrual status at the respective period end.

Troubled Debt Restructuring

A Troubled Debt Restructuring ("TDR") is a situation where we have granted a concession to a borrower for economic or legal reasons related to the borrower's financial difficulties that we would not otherwise consider. A mortgage loan that has been granted new terms, including workout terms as described previously, would be considered a TDR if it meets conditions that would indicate a borrower is experiencing financial difficulty and the new terms constitute a concession on our part. We analyze all loans where we have agreed to workout terms and all loans that we have refinanced to determine if they meet the definition of a TDR. We consider the following factors in determining whether or not a borrower is experiencing financial difficulty:

•borrower is in default,

•borrower has declared bankruptcy,

•there is growing concern about the borrower's ability to continue as a going concern,

•borrower has insufficient cash flows to service debt,

•borrower's inability to obtain funds from other sources, and

•there is a breach of financial covenants by the borrower.

If the borrower is determined to be in financial difficulty, we consider the following conditions to determine if the borrower is granted a concession:

•assets used to satisfy debt are less than our recorded investment,

•interest rate is modified,

•maturity date extension at an interest rate less than market rate,

•capitalization of interest,

•delaying principal and/or interest for a period of three months or more, and

•partial forgiveness of the balance or charge-off.

Mortgage loan workouts, refinances or restructures that are classified as TDRs are individually evaluated and measured for impairment. There were no mortgage loans that we determined to be a TDR at December 31, 2022 and 2021, respectively.
