For the years ended December 31, 2020, 2019 and 2018 our two most significant travel partners, Expedia (and its subsidiaries) and Booking (and its subsidiaries), each accounted for 10% or more of our consolidated revenue and combined accounted for 25%, 33% and 37%, respectively, of our consolidated revenue, with nearly all of this revenue concentrated in our Hotels, Media & Platform segment.

We maintain some cash and cash equivalents balances with financial institutions that are in excess of Federal Deposit Insurance Corporation insurance limits. Our cash and cash equivalents are primarily composed of bank account balances with financial institutions primarily denominated in U.S. dollars, Euros, British pounds, and Australian dollars. We invest in highly-rated corporate debt securities, and our investment policy limits the amount of credit exposure to any one issuer, industry group and currency. Our credit risk related to corporate debt securities is also mitigated by the relatively short maturity period required by our investment policy. Forward contracts are transacted with major international financial institutions with high credit standings, which to date, have typically had maturities of less than 90 days. Our overall credit risk related to accounts receivable is mitigated by the relatively short collection period. </p>
