Schedule of estimates of the fair value of long-term debt

The table below estimates the fair value of long-term debt held by GSWC. The fair values as of June 30, 2019 and December 31, 2018 were determined using rates for similar financial instruments of the same duration utilizing Level 2 methods and assumptions. The interest rates used for the June 30, 2019 valuation decreased as compared to December 31, 2018, increasing the fair value of long-term debt as of June 30, 2019 after taking into account the repayment of $40.0 million of GSWC's 6.70% senior note in March 2019. Changes in the assumptions will produce different results.
