We generally issue senior unsecured notes (“Notes”) for long-term borrowing purposes. Certain of these Notes may have a call feature that allows us to redeem the Notes at any time at our option and/or a put feature that allows a Note holder to redeem the Notes upon the occurrence of both a change in control event and a downgrade of the Notes below an investment grade rating.

On May 5, 2020, we issued $400 aggregate principal amount of additional senior notes pursuant to a reopening of our existing 2.375% Notes due 2025 (the “2025 Notes”), $1,100 aggregate principal amount of 2.250% Notes due 2030 (the “2030 Notes”), and $1,000 aggregate principal amount of 3.125% Notes due 2050 (the “2050 Notes”) under our shelf registration statement. The 2025 Notes constitute an additional issuance of our 2.375% notes due 2025, of which $850 aggregate principal amount was issued on September 9, 2019. Interest on the 2025 Notes is deemed to have accrued from January 15, 2020 and is payable semi-annually in arrears on January 15 and July 15 of each year, commencing July 15, 2020. Interest on the 2030 Notes and 2050 Notes is payable semi-annually in arrears on May 15 and November 15 of each year, commencing November 15, 2020. The proceeds were used for working capital and general corporate purposes, including, but not limited to, repayment of short-term and long-term debt, repurchase of our common stock pursuant to our share repurchase program and to fund acquisitions.

On September 9, 2019, we issued $850 aggregate principal amount of the 2025 Notes, $825 aggregate principal amount of 2.875% Notes due 2029 (the “2029 Notes”), and $825 aggregate principal amount of 3.700% Notes due 2049 (the “2049 Notes”) under our shelf registration statement. Interest on the 2025 Notes is payable semi-annually in arrears on January 15 and July 15 of each year, commencing January 15, 2020. Interest on the 2029 Notes and the 2049 Notes is payable semi-annually in arrears on March 15 and September 15 each year, commencing March 15, 2020.

On May 1, 2018, we settled our Equity Units stock purchase contracts at a settlement rate of 0.2412 shares of our common stock, using a market value formula set forth in the Equity Units purchase contracts. This resulted in the issuance of approximately 6 shares. We had issued 25 Equity Units on May 12, 2015, pursuant to an underwriting agreement dated May 6, 2015, in an aggregate principal amount of $1,250. Each Equity Unit had a stated amount of $50 (whole dollars) and consisted of a purchase contract obligating the holder to purchase a certain number of shares of our common stock on May 1, 2018, subject to earlier termination or settlement, for a price in cash of $50 (whole dollars); and a 5% undivided beneficial ownership interest in $1,000 (whole dollars) principal amount of our 1.900% remarketable subordinated notes (“RSNs”), due 2028. On March 2, 2018, we remarketed the RSNs and used the proceeds to purchase U.S. Treasury securities that were pledged to secure the stock purchase obligations of the holders of the Equity Units. The purchasers of the RSNs transferred the RSNs to us in exchange for $1,250 principal amount of our 4.101% senior notes due 2028 (the “2028 Notes”), and a cash payment of $4. We canceled the RSNs upon receipt and recognized a loss on extinguishment of debt of $18. At the remarketing, we also issued $850 aggregate principal amount of 4.550% notes due 2048 (the “2048 Notes”) under our shelf registration statement. We used the proceeds from the 2048 Notes for working capital and general corporate purposes. Interest on the 2028 Notes and the 2048 Notes is payable semi-annually in arrears on March 1 and September 1 of each year, commencing on September 1, 2018.

The surplus note is an unsecured obligation of Anthem Insurance Companies, Inc. (“Anthem Insurance”), a wholly owned subsidiary, and is subordinate in right of payment to all of Anthem Insurance’s existing and future indebtedness. Any payment of interest or principal on the surplus note may be made only with the prior approval of the Indiana Department of

We have a senior revolving credit facility (the “5-Year Facility”) with a group of lenders for general corporate purposes. The 5-Year Facility provides credit up to $2,500 and matures in June 2024. We also have a 364-day senior revolving credit facility (the “364-Day Facility”) with a group of lenders for general corporate purposes, which provides for credit in the amount of $1,000. In May 2020, we amended and extended the 364-Day Facility, which now matures in June 2021. Our ability to borrow under these credit facilities is subject to compliance with certain covenants, including covenants requiring us to maintain a defined debt-to-capital ratio of not more than 60%, subject to increase in certain circumstances set forth in the applicable credit agreement. As of December 31, 2020, our debt-to-capital ratio, as defined and calculated under the credit facilities, was 37.6%. We do not believe the restrictions contained in any of our credit facility covenants materially affect our financial or operating flexibility. As of December 31, 2020, we were in compliance with all of the debt covenants under these credit facilities. There were no amounts outstanding under the 364-Day Facility at any time during the years ended December 31, 2020 or the year ended December 31, 2019. At December 31, 2020 and December 31, 2019, there were no amounts outstanding under our 5-Year Facility.

We have an authorized commercial paper program of up to $3,500, the proceeds of which may be used for general corporate purposes. At December 31, 2020, we had $250 outstanding under our commercial paper program with a weighted-average interest rate of 0.1600%. At December 31, 2019, we had $400 outstanding under our commercial paper program with a weighted-average interest rate of 1.8528%. Commercial paper borrowings have been classified as long-term debt at December 31, 2020 and 2019, as our general practice and intent is to replace short-term commercial paper outstanding at expiration with additional short-term commercial paper for an uninterrupted period extending for more than one year, and we have the ability to redeem our commercial paper with borrowings under the senior revolving credit facilities described above.

On October 9, 2012, we issued $1,500 of senior convertible debentures (the “Debentures”) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The Debentures are governed by an indenture dated as of October 9, 2012 between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Indenture”). The Debentures bear interest at a rate of 2.750% per year, payable semi-annually in arrears in cash on April 15 and October 15 of each year, and mature on October 15, 2042, unless earlier redeemed, repurchased or converted into shares of common stock at the applicable conversion rate. The Debentures also have a contingent interest feature that will require us to pay additional interest based on certain thresholds and for certain events, as defined in the Indenture, beginning on October 15, 2022.

Holders may convert their Debentures at their option prior to the close of business on the business day immediately preceding April 15, 2042, only under the following circumstances: (1) during any fiscal quarter if the last reported sale price of our common stock for at least 20 trading days during a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five business day period after any 10 consecutive trading day period (the “measurement period”) in which the trading price per $1,000 (whole dollars) principal amount of Debentures for each trading day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on each such day; (3) if we call any or all of the Debentures for redemption, at any time prior to the close of business on the third scheduled trading day prior to the redemption date; or (4) upon the occurrence of specified corporate events, as defined in the Indenture. On and after April 15, 2042 and until the close of business on the third scheduled trading day immediately preceding the Debentures’ maturity date of October 15, 2042, holders may convert their Debentures into common stock at any time irrespective of the preceding circumstances. The Debentures are redeemable at our option at any time on or after October 20, 2022, upon the occurrence of certain events, as defined in the Indenture.

Upon conversion of the Debentures, we will deliver cash up to the aggregate principal amount of the Debentures converted. With respect to any conversion obligation in excess of the aggregate principal amount of the Debentures converted, we have the option to settle the excess with cash, shares of our common stock or a combination thereof based on a daily conversion value, determined in accordance with the Indenture. The initial conversion rate for the Debentures was 13.2319 shares of our common stock per Debenture, which represented a 25% conversion premium based on the closing price of $60.46 per share of our common stock on October 2, 2012 (the date the Debentures’ terms were finalized) and is equivalent to an initial conversion price of $75.575 per share of our common stock.

During the year ended December 31, 2020, $56 aggregate principal amount of the Debentures was surrendered for conversion by certain holders in accordance with the terms and provisions of the Indenture. We elected to settle the excess of the principal amount of the conversions with cash for total payments of $222. We recognized a loss on the extinguishment of debt related to the Debentures of $6, based on the fair values of the debt on the conversion settlement dates. During the year ended December 31, 2019, we repurchased $15 of the aggregate principal balance of the Debentures. In addition, $57 aggregate principal amount of the Debentures was surrendered for conversion by certain holders in accordance with the terms and provisions of the Indenture. We elected to settle the excess of the principal amount of the repurchases and conversions with cash for total payments of $273. We recognized a loss on the extinguishment of debt related to the Debentures of $2. During the year ended December 31, 2018, $109 aggregate principal amount of the Debentures was surrendered for conversion. We elected to settle the excess of the principal amount of the conversions with cash for total payments of $402. We recognized a gain on the extinguishment of debt related to the Debentures of $7.

As of December 31, 2020, our common stock was last traded at a price of $321.09 per share. If the remaining Debentures had been converted or matured at December 31, 2020, we would have been obligated to pay the principal of the Debentures plus an amount in cash or shares equal to $560. The Debentures and underlying shares of our common stock have not been and will not be registered under the Securities Act, or any state securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

We have accounted for the Debentures in accordance with the cash conversion guidance in FASB guidance for debt with conversion and other options. As a result, the value of the embedded conversion option, net of deferred taxes and equity issuance costs, has been bifurcated from its debt host and recorded as a component of additional paid-in capital in our consolidated balance sheets.

The remaining amortization period of the unamortized debt discount as of December 31, 2020 is approximately 22 years. The unamortized discount will be amortized into interest expense using the effective interest method based on an effective interest rate of 5.130%, which represents the market interest rate for a comparable debt instrument that does not have a conversion feature. During the years ended December 31, 2020, 2019 and 2018, we recognized $6, $9 and $12, respectively, of interest expense related to the Debentures, of which $5, $7 and $10, respectively, represented interest expense recognized at the stated interest rate of 2.750% and $1, $2 and $2, respectively, represented interest expense resulting from amortization of the debt discount.
