Schedule of Accounts, Notes, Loans and Financing Receivable [Table Text Block] | Loans Farmer Mac classifies loans as either held for investment or held for sale. Loans held for investment are recorded at the unpaid principal balance, net of unamortized premium or discount and other cost adjustments.

The following table displays the composition of the loan balances as of March 31, 2018 and December 31, 2017: Table 5.1

Allowance for Credit Losses on Financing Receivables [Table Text Block] | Allowance for Losses Farm & Ranch Farmer Mac maintains an allowance for losses presented in two components on its consolidated balance sheets: (1) an allowance for loan losses to account for estimated probable losses on loans held, and (2) a reserve for losses to account for estimated probable losses on loans underlying LTSPCs and off-balance sheet Farmer Mac Guaranteed Securities (excluding AgVantage securities). Farmer Mac's total allowance for losses was $8.5 million as of March 31, 2018 and $8.9 million as of December 31, 2017. See Note 6 for more information about off-balance sheet Farmer Mac Guaranteed Securities and LTSPCs. The following is a summary of the changes in the total allowance for losses for the three months ended March 31, 2018 and 2017: Table 5.2

During first quarter 2018, Farmer Mac recorded releases of its allowance for loan losses and provisions to its reserve for losses of $0.4 million and $21,000, respectively. The net releases to the allowance for loan losses recorded during first quarter 2018 were primarily attributable to (1) paydowns or payoffs of loans with an existing allowance in amounts that exceeded the increase in the allowance associated with net volume growth in Farm & Ranch loans recorded in first quarter 2018, and (2) paydowns on existing substandard loans or an improvement in the risk ratings of certain substandard loans, which resulted in the reduction of the amount of substandard assets rated in the lowest credit quality tier. Farmer Mac recorded no charge-offs to its allowance for loan losses during first quarter 2018. During first quarter 2017, Farmer Mac recorded provisions to its allowance for loan losses of $0.6 million and releases to its reserve for losses of $0.2 million. The provisions to the allowance for loan losses recorded during first quarter 2017 were primarily attributable to an increase in the specific allowance for certain impaired on-balance sheet crop and permanent planting loans resulting from both an increase in the volume of such loans and downgrades in risk ratings on certain loans. The releases to the reserve for losses recorded during the three months ended March 31, 2017 were primarily attributable to (1) a decrease in the general reserve due to improvement in credit quality of certain Agricultural Storage and Processing loans and (2) a net decrease in the balance of loans underlying off-balance sheet Farmer Mac Guaranteed Securities. Farmer Mac recorded $0.2 million of charge-offs to its allowance for loan losses during first quarter 2017. The charge-offs recorded during the first quarter 2017 were primarily related to two impaired crop loans, with one borrower, that were foreclosed and transitioned to REO during first quarter 2017. Farmer Mac had previously recorded a specific allowance of $0.2 million on these impaired crop loans as of December 31, 2016. Subsequent to March 31, 2017, Farmer Mac sold the related properties for $5.7 million and recognized $0.5 million gain on sale of REO.

(1) | Impairment analysis was performed in the aggregate in consideration of similar risk characteristics of the assets and historical statistics on $113.2 million (77 percent) of impaired loans as of December 31, 2017, which resulted in a specific allowance of $2.7 million.
(2) | Includes $15.7 million of loans that are less than 90 days delinquent but which have not met Farmer Mac's performance criteria for returning to accrual status.

For the three months ended March 31, 2018 and 2017, there were no troubled debt restructurings ("TDRs"). As of March 31, 2018 and 2017, there were no TDRs identified during the previous 12 months that were in default under the modified terms. The impact of TDRs on Farmer Mac's allowance for loan losses was immaterial for the three months ended March 31, 2018 and 2017. In accordance with the terms of all LTSPCs, Farmer Mac acquires loans that are either 90 days or 120 days delinquent (depending on the provisions of the applicable agreement) upon the request of the counterparty. Subsequent to the purchase, these defaulted loans are treated as nonaccrual loans and, therefore, interest is accounted for on the cash basis. Any decreases in expected cash flows are recognized as impairment.

(2) | As of second quarter 2017, Farmer Mac revised its calculation of the original loan-to-value ratio of a loan to combine for any cross-collateralized loans: (i) the original loan principal balance amounts in the numerator and (ii) the original appraised property values in the denominator. In previous periods, the ratio was calculated on a loan-by-loan basis without considering the effects of any cross-collateralization. Prior period information has been reclassified to conform to the current period calculation and presentation.
(3) | Includes multiple loans to the same borrower or borrower-related entities.
The original loan-to-value ratio is calculated by dividing the loan principal balance at the time of guarantee, purchase, or commitment by the appraised value at the date of loan origination or, when available, the updated appraised value at the time of guarantee, purchase, or commitment. Current loan-to-value ratios may be higher or lower than the original loan-to-value ratios.
