(1)Fair value is based on observable market prices for the assets. (2)For the portion of this asset class categorized as Level 2, fair value is determined using dealer and broker quotations, certain pricing models, bid prices, quoted prices for similar assets and liabilities in active markets, or other inputs that are observable or can be corroborated by observable market data. (3)Private equity investments are initially valued at cost. Fund managers periodically review the valuations utilizing subsequent company-specific transactions or deterioration in the company’s financial performance to determine if fair value adjustments are necessary. Private equity investments are typically viewed as long term, less liquid investments with return of capital coming via cash distributions from the sale of underlying fund assets. The Plan intends to hold these investments through each fund’s normal life cycle and wind down period. As of December 31, 2020 and 2019, we had $21.9 million and $6.0 million, respectively, of remaining commitments related to these private equity investments. (4)Fair value is reported by the fund manager based on observable market prices for actively traded assets within the funds, as well as financial models, comparable financial transactions or other factors relevant to the specific asset for assets with no observable market. These investments are redeemable quarterly with a range of 30 – 90 days notice. (5)The fair value of Real Assets are reported by the fund manager based on a combination of the following valuation approaches: current replacement cost less deterioration and obsolescence, a discounted cash flow model of income streams, and comparable market sales. As of December 31, 2020 and 2019, we had $0.1 million of remaining commitments related to the real asset investments. The fair value of the postretirement assets at December 31, 2020 and 2019, are as follows:
