For the U.S. Networks segment, 95% of distribution revenue comes from the 10 largest distributors. Agreements in place with the 10 largest cable and satellite operators with the U.S. Networks expire at various times from 2021 through 2023. Although the Company seeks to renew its agreements with its distributors prior to expiration of a contract, a delay in securing a renewal that results in a service disruption, a failure to secure a renewal or a renewal on less favorable terms may have a material adverse effect on the Company’s financial condition and results of operations. Not only could the Company experience a reduction in distribution revenue, but it could also experience a reduction in advertising revenue, as viewership is impacted by affiliate subscriber levels. </span></div><div style="margin-top:5pt;text-indent:22.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">No individual customer accounted for more than 10% of total consolidated revenues for 2020, 2019 or 2018.

The Company manages these credit risks through the evaluation and monitoring of the creditworthiness of, and concentration of risk with, the respective counterparties. In this regard, credit risk associated with outstanding derivative financial instruments is spread across a relatively broad counterparty base of banks and financial institutions. The Company also has a limited number of arrangements where collateral is required to be posted in the instance that certain fair value thresholds are exceeded.
