The following table displays the composition of the loan balances as of June 30, 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 $9.0 million as of June 30, 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 and six months ended June 30, 2018 and 2017: Table 5.2

During second quarter 2018, Farmer Mac recorded a provision to both its allowance for loan losses and reserve for losses of $0.4 million and $0.2 million, respectively. The net provisions to the total allowance for loan losses recorded during second quarter 2018 were attributable to (1) a modest decline in overall portfolio credit quality, and (2) an increase in the general allowance due to net volume growth in both on and off-balance sheet Farm & Ranch loans, primarily related to new agricultural storage and processing loans purchased during second quarter 2018. Farmer Mac recorded no charge-offs to its allowance for loan losses during second quarter 2018. During second quarter 2017, Farmer Mac recorded provisions to its allowance for loan losses and reserve for losses of $0.3 million and $0.1 million, respectively. The provisions to the allowance for loan losses recorded during the second quarter 2017 were primarily attributable to an increase in the general allowance due to overall net volume growth in on-balance sheet Farm & Ranch loans. The provision to the reserve for losses recorded during the second quarter 2017 was primarily attributable to an increase in the general reserve due to downgrades in risk ratings on certain unimpaired crop and permanent planting loans underlying LTSPCs and off-balance sheet Farmer Mac Guaranteed Securities. Farmer Mac recorded no charge-offs to its allowance for loan losses during the second quarter 2017.

For the three and six months ended June 30, 2018, there were no troubled debt restructurings ("TDRs"). For the three and six months ended June 30, 2017, the recorded investment of loans determined to be TDRs was $0.2 million both before and after restructuring. As of June 30, 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 and six months ended June 30, 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.
