Fair Value of Financial Instruments
FASB ASC 820, Fair Value Measurement, establishes a fair value hierarchy that distinguishes between assumptions based on market data (observable inputs) and the Company's assumptions (unobservable inputs). The hierarchy consists of three levels, as follows:
Level 1 - Quoted market prices in active markets for identical assets or liabilities
Level 2 - Inputs other than Level 1 that are either directly or indirectly observable
Level 3 - Unobservable inputs developed using the Company's estimates and assumptions, which reflect those that the Company believes market participants would use.
Financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021 were as follows (in thousands):

(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 and are valued at amortized cost, which approximates fair value. The increase is primarily driven by additional funds received in growth areas of several utilities.
(2) Demand Deposit is presented on the Cash and cash equivalents line item of the Company's consolidated balance sheets and is valued at amortized cost, which approximates fair value.
(3) The fair value of our debt was estimated based on interest rates considered available for instruments of similar terms and remaining maturities.
(4) As part of the Red Rock acquisition, the Company is required to pay to the seller a growth premium equal to $750 (not in thousands) for each new account established within three specified growth premium areas, commencing in each area on the date of the first meter installation and ending on the earlier of ten years after such first installation date, or twenty years from the acquisition date. 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.
