Recorded in other income (expense), net in the consolidated statements of net and comprehensive income. The cost basis of securities sold were determined based on the specific identification method.
The Company invests its excess cash in a diversified portfolio of fixed and variable rate debt securities to meet current and future cash flow needs. All investments are made in accordance with the Company’s approved investment policy. As of December 31, 2020, the portfolio had an average credit rating of AA and weighted term to final maturity of 1.6 years, with 29 securities in the portfolio with an unrealized loss aggregating $50,000, or 0.1% of amortized cost, and a weighted average credit rating of AA+.
As of December 31, 2020, the Company performed an impairment analysis and determined an allowance for credit losses was not required. The Company determined that it did not have an intent to sell and it was not more likely than not that the Company would be required to sell any security based on its current liquidity position, or to maintain compliance with its investment policy, specifically as it relates to minimum credit ratings. The Company evaluated the securities with an unrealized loss considering severity of loss, credit ratings, specific credit events during the period since acquisition, overall likelihood of default, market sector, potential impact
 
from the current economic situation and a review of an issuer’s and securities liquidity and financial strength, as needed. The Company concluded that it would receive all scheduled interest and principle payments. The Company, therefore, determined qualitatively that the unrealized loss was related to changes in interest rates and other market factors and therefore no allowance for credit losses was required.
Amortized cost and fair value of marketable debt securities,
