Our actual results could differ materially from these estimated amounts. Our most significant estimates are our allowance for credit losses in receivables, valuation of goodwill and intangible assets, amortization of program rights and intangible assets, pension costs, income taxes, employee medical insurance claims, useful lives of property and equipment and contingencies.</p> <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:22.3pt;"> </p>

Credit is extended based on an evaluation of the customer’s financial condition, and generally advance payment is <em style="font: inherit;">not</em> required, except for political advertising. Credit losses are provided for in the financial statements and consistently have been within our expectations that are based upon our prior experience.</p> <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;"><i> </i></p> <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:22.3pt;">Excluding political advertising revenue, which is cyclical based on election cycles, our most significant category of customer is automotive. During the years ended <em style="font: inherit;"> December 31, 2020, </em><em style="font: inherit;">2019</em> and <em style="font: inherit;">2018</em> approximately 21%, 25% and 25%, respectively, of our broadcast advertising revenue (excluding political advertising revenue) was obtained from advertising sales to automotive customers. Although our revenues can be affected by changes within our customer base, we believe this risk is in part mitigated due to the fact that <em style="font: inherit;">no</em> <em style="font: inherit;">one</em> customer accounted for in excess of <em style="font: inherit;">5%</em> of our broadcast advertising revenue in any of these periods. Furthermore, we believe that our large geographic operating area partially mitigates the potential effect of regional economic impacts.</p> <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:22.3pt;"> </p>
