Any such sales were made in accordance with our risk-management policies and practices.
Held to Maturity Debt Securities by Credit Quality | The following table presents the credit quality of our held-to-maturity securities, based on the latest available information as of June 30, 2020. The credit ratings are sourced from nationally recognized statistical rating organizations, which include S&P, Moody’s, and Fitch, and represent a composite of the ratings or, where credit ratings cannot be sourced from the agencies, are presented based on the asset type. All our held-to-maturity securities were current in their payment of principal and interest as of June 30, 2020. We have not recorded any interest income reversals on our held-to-maturity securities during the six months ended June 30, 2020.

(a) Rating agencies indicate that they base their ratings on many quantitative and qualitative factors, which may include capital adequacy, liquidity, asset quality, business mix, level and quality of earnings, and the current operating, legislative, and regulatory environment. A credit rating is not a recommendation to buy, sell, or hold securities, and the ratings are subject to revision or withdrawal at any time by the assigning rating agency.
Schedule of Unrealized Loss on Investments | The following table summarizes held-to-maturity securities in an unrealized loss position at December 31, 2019, prior to the date of adoption of the amendments to the credit loss standard, and as defined by the previous accounting guidance in effect at that time.

The table below summarizes available-for-sale securities in an unrealized loss position, which we evaluated to determine if a credit loss exists requiring the recognition of an allowance for credit losses. For additional information on our methodology, refer to Note 1. As of June 30, 2020, we did not have the intent to sell the available-for-sale securities with an unrealized loss position and we do not believe it is more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. As a result of this evaluation, management determined that no credit reserves were required at June 30, 2020. We have not recorded any interest income reversals on our available-for-sale securities during the six months ended June 30, 2020.
