Elk River Municipal Utilities Elk River, Minnesota Notes to the Financial Statements December 31, 2017 Note 3: Defined Benefit Pension Plans - Statewide (Continued) F. Discount Rate The discount rate used to measure the total pension liability in 2017 was 7.50 percent. The projection of cash flows used to determine the discount rate assumed that contributions from plan members and employers will be made at rates set in Minnesota statutes. Based on these assumptions, the fiduciary net position of the GERF was projected to be available to make all projected future benefit payments of current plan members. Therefore, the long-term expected rate of return on pension plan investments was applied to all periods of projected benefit payments to determine the total pension liability. G. Pension Liability Sensitivity The following presents the Utilities proportionate share of the net pension liability for all plans it participates in, calculated using the discount rate disclosed in the preceding paragraph, as well as what the Utilities proportionate share of the net pension liability would be if it were calculated using a discount rate 1 percentage point lower or 1 percentage point higher than the current discount rate: Utilities Proportionate Share of NPL 1 Percent 1 Percent Decrease (6.50%) Current(7.50%) Increase (8.50%) GERF $ 5,347,056 $ 3,447,324 $ 1,892,049 H.

Territorial Acquisition Agreement In 1991, the Utilities entered into a 20 year agreement to transfer ownership of electric plant and electric service to customers in certain areas receiving electric service from Anoka Electric Cooperative, Inc. (AEC). In 2010 the Utility completed the final purchase under this agreement. The agreed cost of property purchased from AEC is net book value. The Utilities also pays AEC for loss of revenue for each area acquired based on a formula outlined in the agreement. In addition, the Utilities will compensate AEC for the loss of revenue from the future sale of electricity to electric customers in the areas acquired from AEC for a period of ten years from the date of sale of each individual area. The Utilities paid $268 in 2017 for loss of revenues under this agreement. All amounts paid are included in property and equipment. In 2015, the Utilities entered into an agreement to transfer ownership of electric plant and electric service to customers in eight designated areas receiving service from Connexus Energy. Specific payment terms have been negotiated for 5 years, and if any of the eight areas are not acquired within this timeframe, the payment terms may be renegotiated. The agreed cost of property purchased from Connexus Energy is net book value, integration expenses, and a loss of revenue payment. The loss of revenue payment for each area acquired is based on a formula outlined in the agreement, payable for the subsequent ten years after initial purchase. 44 1ns
