(1) HUF Funds - restricted cash and Certificate of Deposit - Restricted are presented on the Restricted cash line item of the Company's consolidated balance sheets. They are valued at amortized cost, which approximates fair value.

The fair value of the acquisition liability was calculated using a discounted cash flow technique which utilized unobservable inputs developed using the Company's estimates and assumptions. Significant inputs used in the fair value calculation are as follows: year of the first meter installation, total new accounts per year, years to complete full build out, and discount rate
