For available-for-sale debt securities that have unrealized losses, the Company assesses impairment by evaluating various factors, including whether (i) it has the intention to sell any of these investments and (ii) whether it is more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. The Company periodically assesses performance indicators of the investment by evaluating various factors such as (i) changes in the credit ratings and (ii) review of the issuer. As of June 30, 2020, the Company had 121 investments in unrealized loss positions. The gross unrealized losses related to these investments were primarily due to changes in market interest rates. The Company anticipates that it will recover the entire amortized cost basis of such available-for-sale debt securities and has determined that no allowance for credit losses was required to be recognized during the three and six months ended June 30, 2020 and June 30, 2019.

During the three and six months ended June 30, 2020 and June 30, 2019, there were no material gross realized gains or losses from available-for-sale debt securities.
