which in turn pays partnership distributions to the participating associations. We received a partnership distribution in an amount that approximated our share of the net earnings of the loans in the program, adjusted for required return on capital and servicing and origination fees. No partnership distributions were received in 2016 or 2015. Operating Expenses Components of Operating Expenses (dollars in thousands) For the year ended December 31 2017 2016 2015 Salaries and employee benefits Purchased and vendor services Communications Occupancy and equipment Advertising and promotion Examination Farm Credit System insurance Other $27,992 5,372 1,037 3,514 1,624 1,022 4,453 2,977 $28,237 4,162 1,041 3,367 1,814 912 4,918 2,902 $28,850 3,948 968 3,147 1,641 777 3,456 3,157 Total operating expenses $47,991 $47,353 $45,944 1.3% 1.3% 1.4% Operating rate The Farm Credit System insurance expense decreased in 2017 primarily due to a lower premium rate charged by FCSIC on accrual loans from 16 basis points for the first half and 18 basis points for the second half of 2016 to 15 basis points for the calendar year 2017. The FCSIC has announced premiums will decrease to 9 basis points for 2018. The FCSIC Board meets periodically throughout the year to review premium rates and has the ability to change these rates at any time. Provision for Income Taxes The variance in provision for income taxes was related to our estimate of taxes based on taxable income. Patronage distributions to members reduced our tax liability in 2017, 2016, and 2015. Additional discussion is included in Note 8 to the accompanying Consolidated Financial Statements. FUNDING AND LIQUIDITY We borrow from AgriBank, under a note payable, in the form of a line of credit, as described in Note 6 to the accompanying Consolidated Financial Statements. This line of credit is our primary source of liquidity and is used to fund operations and meet current obligations. At December 31, 2017, we had $355.2 million available under our line of credit. We generally apply excess cash to this line of credit. Note Payable Information (dollars in thousands) For the year ended December 31 Average balance Average interest rate 2017 2016 2015 $3,022,871 $2,926,836 $2,668,861 2.1% 1.8% 1.7% The repricing attributes of our line of credit generally correspond to the repricing attributes of our loan portfolio which significantly reduces our market interest rate risk. Due to the cooperative structure of the Farm Credit System and as we are a stockholder of AgriBank, we expect this borrowing relationship to continue into the foreseeable future. Our other source of lendable funds is from unallocated surplus. CAPITAL ADEQUACY Total members’ equity was $801.8 million, $753.7 million, and $704.9 million at December 31, 2017, 2016, and 2015, respectively. Total members’ equity increased $48.0 million from December 31, 2016, primarily due to net income for the year partially offset by patronage distribution accruals. The FCA Regulations require us to maintain minimums for various regulatory capital ratios. New regulations became effective January 1, 2017, which replaced the previously required core surplus and total surplus ratios with common equity tier 1, tier 1 capital, and total capital risk-based capital ratios. The new regulations also added tier 1 leverage and unallocated retained earnings and equivalents ratios. The permanent capital ratio continues to remain in effect with some modifications to align with the new regulations. 7
