Current Market • December 6th Board meeting -- Board approved moving forward with the refunding • Based on the current interest rate environment, it is a prudent time for the District to refinance the 2002 Bonds and provide savings to property owners in the District Interest rate movement since mid-October 2018 • Current interest rate is 5.00% -- Refunding is anticipated to lower interest rate to below 3.50% with an all-in interest cost (including all issuance expenses) to about 3.75% • Estimated Annual Average Cash Flow Savings – approx. $104,000 / year • Estimated Total Cash Flow Savings – approx. $1,370,000

9. III. Additional Refunding Benefits

10. Additional Refunding Benefits In addition to providing cash flow savings to property owners in the Assessment District, the Refunding will: • Eliminate an amount of $247,334 owed by the District to the reserve fund for the 2002 Bonds, thus freeing up funds in the general fund for other District purposes. • Reconcile and eliminate a debt variance that has developed over time, that could lead to the risk of future default. The debt variance is approximately $9,000 a year.

12. Debt Variance • There is currently a greater amount of debt service on the 2002 Bonds than is available to collect from assessment liens in the Assessment District, leaving risk of future default. • Refinancing the 2002 Bonds would reconcile/eliminate this debt variance, preventing a potential default while saving property owners money.
