Nonrecurring fair value measurements

During the years ended December 31, 2019 and 2018, we recorded impairment charges for cost method investments in the amount of $21.2 million and $12.0 million, respectively. In 2018, a valuation method using prices in active markets was utilized to determine the fair value. In 2019, we determined the value using unobservable inputs and wrote the balance of the cost method investments to zero.
