NOTE 4—LOANS
        
We segregate our loan portfolio into segments, by legal entity, based on the borrower member class, which consists of CFC distribution, CFC power supply, CFC statewide and associate, NCSC and RTFC. We offer both long-term and line of credit loans to our borrowers. Under our long-term loan facilities, a borrower may select a fixed interest rate or a variable interest rate at the time of each loan advance. Line of credit loans are revolving loan facilities and generally have a variable interest rate.

Loans to Members

Loans to members consist of total loans outstanding, which reflects the unpaid principal balance, net of charge-offs and recoveries, of loans and deferred loan origination costs. The following table presents loans to members, by member class and by loan type, as of February 28, 2022 and May 31, 2021.

Loan Sales

We may transfer whole loans and participating interests to third parties. These transfers are typically made concurrently with the closing of the loan or participation agreement at par value and meet the accounting criteria required for sale accounting. We sold CFC loans, at par for cash, totaling $64 million and $126 million during the nine months ended February 28, 2022 and 2021, respectively. We recorded immaterial losses on the sale of these loans.

Accrued Interest Receivable

We report accrued interest on loans separately on our consolidated balance sheets as a component of the line item accrued interest receivable rather than as a component of loans to members. Accrued interest receivable amounts generally represent three months or less of accrued interest on loans outstanding. Because our policy is to write off past-due accrued interest receivable in a timely manner, we elected not to measure an allowance for credit losses for accrued interest receivable on loans outstanding, which totaled $96 million and $93 million as of February 28, 2022 and May 31, 2021, respectively. We also elected to exclude accrued interest receivable from the credit quality disclosures required under CECL.
Credit Concentration

Concentrations of credit may exist when a lender has large credit exposures to single borrowers, large credit exposures to borrowers in the same industry sector or engaged in similar activities or large credit exposures to borrowers in a geographic region that would cause the borrowers to be similarly impacted by economic or other conditions in the region. As a tax-exempt, member-owned finance cooperative, CFC’s principal focus is to provide funding to its rural electric utility cooperative members to assist them in acquiring, constructing and operating electric distribution systems, power supply systems and related facilities.

Because we lend primarily to our rural electric utility cooperative members, we have had a loan portfolio subject to single-industry and single-obligor concentration risks since our inception in 1969. Loans outstanding to electric utility organizations of $29,051 million and $27,995 million as of February 28, 2022 and May 31, 2021, respectively, accounted for 98% and 99% of total loans outstanding as of each respective date. The remaining loans outstanding in our portfolio were to RTFC members, affiliates and associates in the telecommunications industry.

Single-Obligor Concentration

The outstanding loan exposure for our 20 largest borrowers totaled $6,213 million and $6,182 million as of February 28, 2022 and May 31, 2021, respectively, representing 21% and 22% of total loans outstanding as of each respective date. The 20 largest borrowers consisted of 12 distribution systems and eight power supply systems as of February 28, 2022. The 20 largest borrowers consisted of 10 distribution systems and 10 power supply systems as of May 31, 2021. The largest total outstanding exposure to a single borrower or controlled group represented less than 2% of total loans outstanding as of both February 28, 2022 and May 31, 2021.

As part of our strategy in managing credit exposure to large borrowers, we entered into a long-term standby purchase commitment agreement with Farmer Mac during fiscal year 2016. Under this agreement, we may designate certain long-term loans to be covered under the commitment, subject to approval by Farmer Mac, and in the event any such loan later goes into payment default for at least 90 days, upon request by us, Farmer Mac must purchase such loan at par value. We are required to pay Farmer Mac a monthly fee based on the unpaid principal balance of loans covered under the purchase commitment. The aggregate unpaid principal balance of designated and Farmer Mac approved loans was $471 million and $512 million as of February 28, 2022 and May 31, 2021, respectively. Loan exposure to our 20 largest borrowers covered under the Farmer Mac agreement totaled $290 million and $309 million as of February 28, 2022 and May 31, 2021, respectively, which reduced our exposure to the 20 largest borrowers to 20% and 21% as of each respective date. We have had no loan defaults for loans covered under this agreement; therefore, no loans had been put to Farmer Mac for purchase pursuant to the standby purchase agreement as of February 28, 2022. Our credit exposure is also mitigated by long-term loans guaranteed by RUS. Guaranteed RUS loans totaled $133 million and $139 million as of February 28, 2022 and May 31, 2021, respectively.

Geographic Concentration

Although our organizational structure and mission results in single-industry concentration, we serve a geographically diverse group of electric and telecommunications borrowers throughout the U.S. The consolidated number of borrowers with loans outstanding totaled 885 and 892 as of February 28, 2022 and May 31, 2021 located in 49 states. Texas, which had 67 borrowers with loans outstanding as of both February 28, 2022 and May 31, 2021, respectively, accounted for the largest number of borrowers with loans outstanding in any one state as of each respective date. Texas also accounted for the largest concentration of loan exposure in any one state as of each respective date. Loans outstanding to Texas-based electric utility organizations totaled $4,955 million and $4,878 million as of February 28, 2022 and May 31, 2021, respectively and accounted for approximately 17% of total loans outstanding as of each respective date. Of the loans outstanding to Texas-based electric utility organizations, $165 million and $172 million as of February 28, 2022 and May 31, 2021, respectively,
were covered by the Farmer Mac standby repurchase agreement, respectively, which reduced our credit risk exposure to Texas-based borrowers to 16% of total loans outstanding as of each respective date.

Credit Quality Indicators

Assessing the overall credit quality of our loan portfolio and measuring our credit risk is an ongoing process that involves tracking payment status, troubled debt restructurings, nonperforming loans, charge-offs, the internal risk ratings of our borrowers and other indicators of credit risk. We monitor and subject each borrower and loan facility in our loan portfolio to an individual risk assessment based on quantitative and qualitative factors. Payment status trends and internal risk ratings are indicators, among others, of the probability of borrower default and overall credit quality of our loan portfolio.

Payment Status of Loans

Loans are considered delinquent when contractual principal or interest amounts become past due 30 days or more following the scheduled payment due date. Loans are placed on nonaccrual status when payment of principal or interest is 90 days or more past due or management determines that the full collection of principal and interest is doubtful. The following table presents the payment status, by legal entity and member class, of loans outstanding as of February 28, 2022 and May 31, 2021.

We had one borrower, Brazos Electric Power Cooperative, Inc. (“Brazos”), with delinquent loans totaling $86 million and $85 million as of February 28, 2022 and May 31, 2021, respectively. Brazos, a CFC Texas-based power supply borrower, filed for bankruptcy in March 2021 due to its exposure to elevated wholesale electric power costs during the February 2021 polar vortex. Brazos is not permitted to make scheduled loan payments without approval of the bankruptcy court. As a result, we have not received payments from Brazos since March 2021, and its loans outstanding to us were on nonaccrual status as of each respective date. The decrease in loans on nonaccrual status of $30 million to $207 million as of February 28, 2022, from $237 million was due to the receipt of loan principal payments. See “Nonperforming Loans” below for additional information.

TDRs

We have not had any loan modifications that were required to be accounted for as a TDR since fiscal year 2016. The following table presents the outstanding balance of modified loans accounted for as TDRs in prior periods and the performance status, by legal entity and member class, of these loans as of February 28, 2022 and May 31, 2021.

There were no unadvanced commitments related to these loans as of February 28, 2022 and May 31, 2021. These loans, which have been performing in accordance with the terms of their respective restructured loan agreement for an extended period of time, were classified as performing and on accrual status as of February 28, 2022 or May 31, 2021. We did not have any TDR loans classified as nonperforming as of February 28, 2022 or May 31, 2021.

Nonperforming Loans

In addition to TDR loans that may be classified as nonperforming, we also may have nonperforming loans that have not been modified as a TDR. The following table presents the outstanding balance of nonperforming loans, by legal entity and member class, as of February 28, 2022 and May 31, 2021. Loans classified as nonperforming are placed on nonaccrual status.

(2) In addition, we had less than $1 million letters of credit outstanding to Brazos as of May 31, 2021.

We had loans to two borrowers totaling $207 million classified as nonperforming as of February 28, 2022. In comparison we had loans to four borrowers totaling $237 million classified as nonperforming as of May 31, 2021. Nonperforming loans represented 0.70% and 0.84% of total loans outstanding as of February 28, 2022 and May 31, 2021, respectively. The reduction in nonperforming loans of $30 million during the nine months ended February 28, 2022 was due in part to our receipt during the fiscal quarter ended November 30, 2021 (the “second quarter of fiscal year 2022”) of full payment of all amounts due on nonperforming loans to two RTFC borrowers totaling $9 million. In addition, we have continued to receive payments on the remaining outstanding nonperforming loan to a CFC electric power supply borrower, including payments totaling $22 million during the nine months ended February 28, 2022, which reduced the balance of this loan to $121 million as of February 28, 2022, from $143 million as of May 31, 2021.

Loans outstanding to Brazos classified as nonperforming totaled $86 million and $85 million as of February 28, 2022 and May 31, 2021, respectively. As discussed above, Brazos, which filed for bankruptcy in March 2021, is not permitted to make scheduled loan payments without approval of the bankruptcy court. See “Note 15—Subsequent Events” for developments in March 2022 related to Brazos Sandy Creek Electric Cooperative Inc. (“Brazos Sandy Creek”), a wholly-owned subsidiary of Brazos and a CFC Texas-based electric power supply borrower.

Net Charge-Offs

We had no loan charge-offs during the nine months ended February 28, 2022, nor during the same prior-year period. Prior to Brazos’ bankruptcy filing, we had not experienced any defaults or charge-offs in our electric utility and telecommunications loan portfolios since fiscal year 2013 and 2017, respectively.

Borrower Risk Ratings

As part of our management of credit risk, we maintain a credit risk rating framework under which we employ a consistent process for assessing the credit quality of our loan portfolio. We evaluate each borrower and loan facility in our loan portfolio and assign internal borrower and loan facility risk ratings based on consideration of a number of quantitative and qualitative factors. We categorize loans in our portfolio based on our internally assigned borrower risk ratings, which are intended to assess the general creditworthiness of the borrower and probability of default. Our borrower risk ratings align with the U.S. federal banking regulatory agencies credit risk definitions of pass and criticized categories, with the criticized category further segmented among special mention, substandard and doubtful. Pass ratings reflect relatively low probability of default, while criticized ratings have a higher probability of default.
The following is a description of the borrower risk rating categories.

•Pass:  Borrowers that are not experiencing difficulty and/or not showing a potential or well-defined credit weakness.
•Special Mention:  Borrowers that may be characterized by a potential credit weakness or deteriorating financial condition that is not sufficiently serious to warrant a classification of substandard or doubtful.
•Substandard:  Borrowers that display a well-defined credit weakness that may jeopardize the full collection of principal and interest.
•Doubtful:  Borrowers that have a well-defined credit weakness or weaknesses that make full collection of principal and interest, on the basis of currently known facts, conditions and collateral values, highly questionable and improbable.

Our internally assigned borrower risk ratings serve as the primary credit quality indicator for our loan portfolio. Because our internal borrower risk ratings provide important information on the probability of default, they are a key input in determining our allowance for credit losses.

Table 4.5 displays total loans outstanding, by borrower risk rating category and by legal entity and member class, as of February 28, 2022 and May 31, 2021. The borrower risk rating categories presented below correspond to the borrower risk rating categories used in calculating our collective allowance for credit losses. If a parent company provides a guarantee of full repayment of loans of a subsidiary borrower, we include the loans outstanding in the borrower risk-rating category of the guarantor parent company rather than the risk rating category of the subsidiary borrower for purposes of calculating the collective allowance.

We present term loans outstanding as of February 28, 2022, by fiscal year of origination for each year during the five-year annual reporting period beginning in fiscal year 2018, and in the aggregate for periods prior to fiscal year 2018. The origination period represents the date CFC advances funds to a borrower, rather than the execution date of a loan facility for a borrower. Revolving loans are presented separately due to the nature of revolving loans. The substantial majority of loans in our portfolio represent fixed-rate advances under secured long-term facilities with terms up to 35 years, and as indicated in Table 4.5 below, term loan advances made to borrowers prior to fiscal year 2018 totaled $16,825 million, representing 57% of our total loans outstanding of $29,508 million as of February 28, 2022. The average remaining maturity of our long-term loans, which accounted for 92% of total loans outstanding as of February 28, 2022, was 18 years.

As discussed above, as a member-owned finance cooperative, CFC’s principal focus is to provide funding to its rural electric utility cooperative members to assist them in acquiring, constructing and operating electric distribution systems, power supply systems and related facilities. As such, since our inception in 1969 we have had an extended repeat lending and repayment history with substantially all of member borrowers through our various loan programs. Our secured long-term loan commitment facilities typically provide a five-year draw period under which a borrower may draw funds prior to the expiration of the commitment. Because our electric utility cooperative borrowers must make substantial annual capital investments to maintain operations and ensure delivery of the essential service provided by electric utilities, they require a continuous inflow of funds to finance infrastructure upgrades and new asset purchases. Due to the funding needs of electric utility cooperatives, a CFC borrower generally has multiple loans outstanding under advances drawn in different years.

While the number of borrowers with loans outstanding was 885 borrowers as of February 28, 2022, the number of loans outstanding was 16,572 as of February 28, 2022, resulting in an average of 19 loans outstanding per borrower. Our borrowers, however, are subject to cross-default under the terms of our loan agreements. Therefore, if a borrower defaults on one loan, the borrower is considered in default on all outstanding loans. Due to these factors, we historically have not observed a correlation between the year of origination of our loans and default risk. Instead, default risk on our loans has typically been more closely correlated to the risk rating of our borrowers.

Criticized loans totaled $504 million and $886 million as of February 28, 2022 and May 31, 2021, respectively, and represented approximately 2% and 3% of total loans outstanding as of each respective date. Criticized loans include loans outstanding to Brazos of $86 million and $85 million as of February 28, 2022 and May 31, 2021, respectively, which were classified as doubtful as of each respective date. Each of the borrowers with loans outstanding in the criticized category, with the exception of Brazos, was current with regard to all principal and interest amounts due as of February 28, 2022 and May 31, 2021. Brazos is not permitted to make scheduled loan payments without approval of the bankruptcy court.

Special Mention

One CFC electric distribution borrower with loans outstanding of $250 million and $219 million as of February 28, 2022 and May 31, 2021, respectively, accounted for the substantial majority of loans in the special mention loan category amount of $297 million and $269 million as of each respective date. This borrower experienced an adverse financial impact from restoration costs incurred to repair damage caused by two successive hurricanes. We expect that the borrower will receive grant funds from the Federal Emergency Management Agency and the state where it is located for the full reimbursement of the hurricane damage-related restoration costs.

Substandard

We did not have any loans classified as substandard as of February 28, 2022. We had loans outstanding to Rayburn Country Electric Cooperative, Inc. (“Rayburn”) totaling $379 million that were classified as substandard as of May 31, 2021. In February 2022, Rayburn successfully completed a securitization transaction to cover extraordinary costs and expenses incurred during the February 2021 polar vortex pursuant to a financing program enacted into law by Texas in June 2021 for qualifying electric cooperatives exposed to elevated power costs during the February 2021 polar vortex. Subsequent to the completion of the securitization transaction, Rayburn fully paid its outstanding obligations to the Electric Reliability Council of Texas. As a result, we revised our borrower risk rating for Rayburn to a rating in the pass category from a previous rating in the substandard category. In addition, we received loan payments from Rayburn during the three months ended February 28, 2022 that reduced our loans outstanding to Rayburn to $207 million as of February 28, 2022 from $379 million as of May 31, 2021.

Doubtful

Loans outstanding classified as doubtful totaled $207 million and $237 million as of February 28, 2022 and May 31, 2021, respectively, consisting of loans outstanding to Brazos of $86 million and $85 million as of each respective date and loans outstanding to a CFC electric power supply borrower of $121 million and $143 million as of each respective date. These loans were also classified as nonperforming, as discussed above under “Nonperforming Loans.” As discussed above, in June 2021, Texas enacted securitization legislation that offers a financing program for qualifying electric cooperatives exposed to elevated power costs during the February 2021 polar vortex. Brazos qualifies for the Texas-enacted financing program.

____________________________
(1)The interest rate on unadvanced loan commitments is not set until an advance is made; therefore, all unadvanced long-term loan commitments are reported as variable rate. However, the borrower may select either a fixed or a variable rate when an advance is drawn under a loan commitment.

The following table displays, by loan type, the available balance under unadvanced loan commitments as of February 28, 2022, and the related maturities in each fiscal year during the five-year period ended May 31, 2026, and thereafter.

Unadvanced line of credit commitments accounted for 63% of total unadvanced loan commitments as of February 28, 2022, while unadvanced long-term loan commitments accounted for 37% of total unadvanced loan commitments. Unadvanced line of credit commitments are typically revolving facilities for periods not to exceed five years. Unadvanced line of credit commitments generally serve as supplemental back-up liquidity to our borrowers. Historically, borrowers have not drawn the full commitment amount for line of credit facilities, and we have experienced a very low utilization rate on line of credit loan facilities regardless of whether or not we are obligated to fund the facility where a material adverse change exists.

Our unadvanced long-term loan commitments have a five-year draw period under which a borrower may draw funds prior to the expiration of the commitment. We expect that the majority of the long-term unadvanced loan commitments of $5,230 million will be advanced prior to the expiration of the commitment.
Because we historically have experienced a very low utilization rate on line of credit loan facilities, which account for the majority of our total unadvanced loan commitments, we believe the unadvanced loan commitment total of $14,161 million as of February 28, 2022 is not necessarily representative of our future funding requirements.

Unadvanced Loan Commitments—Conditional

The substantial majority of our line of credit commitments and all of our unadvanced long-term loan commitments include material adverse change clauses. Unadvanced loan commitments subject to material adverse change clauses totaled $10,969 million and $11,312 million as of February 28, 2022 and May 31, 2021, respectively. Prior to making an advance on these facilities, we confirm that there has been no material adverse change in the business or condition, financial or otherwise, of the borrower since the time the loan was approved and confirm that the borrower is currently in compliance with loan terms and conditions. In some cases, the borrower’s access to the full amount of the facility is further constrained by the designated purpose, imposition of borrower-specific restrictions or by additional conditions that must be met prior to advancing funds.

Unadvanced Loan Commitments—Unconditional

Unadvanced loan commitments not subject to material adverse change clauses at the time of each advance consisted of unadvanced committed lines of credit totaling $3,192 million and $3,045 million as of February 28, 2022 and May 31, 2021, respectively. As such, we are required to advance amounts on these committed facilities as long as the borrower is in compliance with the terms and conditions of the facility. The following table summarizes the available balance under unconditional committed lines of credit as of February 28, 2022, and the related maturity amounts in each fiscal year during the five-year period ending May 31, 2026, and thereafter.

Pledged Collateral—Loans

We are required to pledge eligible mortgage notes in an amount at least equal to the outstanding balance of our secured debt. Table 4.9 displays the borrowing amount under each of our secured borrowing agreements and the corresponding loans outstanding pledged as collateral as of February 28, 2022 and May 31, 2021. See “Note 6—Short-Term Borrowings” and “Note 7—Long-Term Debt” for information on our secured borrowings and other borrowings.
