These investments were issued by highly rated corporations. Accordingly, the securities were not settled at a price less than the amortized cost of the Group’s investment. As of December 31, 2018, the Group did not have any investments in marketable securities that were in an unrealized loss position for a period of twelve months or greater. Since the Group had the ability and intent to hold these investments until an anticipated recovery of fair value, which was until maturity, the Group did not consider these investments to be other-than-temporarily impaired as of December 31, 2018. Unrealized gains (losses) are valued using alternative pricing sources and models utilizing observable market inputs.

As of December 31, 2019, the Group did not have any investments in marketable securities.
