7. 7 How does a Regulated Utility function? An Investor Owned Utility (“IOU”) takes on the “obligation to serve” in a franchise territory The company invests to construct facilities A regulated return on equity of approximately 10% is currently allowed by a regulatory bodies (depending on level of interest rates) Operations are transparent

8. 8 A method to access and repay FEMA loans City forms W&S authority with powers to borrow, contract and grant a franchise. BOD appointed, not elected. W&SA contracts with AW on cost plus basis to design system for not to exceed price. AW designs system and forms IOU. AW commits to buy system (or parts thereof) as parts go commercial. D/E, required debt ratings and ROE agreed at outset. City accepts design and applies to FEMA for loan and fast track permits & approvals. W&SA grants franchise to AW.

9. 9 A method to access and repay FEMA loans (continued) AW builds system using cost plus, open book approach. Maximum use of local content. City pays on % completion basis. AW buys back parts of system as they become commercial. City repays FEMA with proceeds of sales to AW. AW owns and operates system under local W&S Authority regulation or state DPU, as preferred.
