In connection with the exchange offer, we solicited and received the requisite number of consents to amend the indentures governing the remaining outstanding capital securities to eliminate various terms and conditions and other provisions, including the covenant that required us to make interest payments in accordance with an alternative coupon satisfaction mechanism upon the occurrence of certain trigger events. During 2020, we redeemed our $296 million outstanding principal amount of 4.85% senior notes due 2021 and repaid our $500 million LIBOR + 150 bps term loan due 2022. During 2019, we repurchased $105 million of our 6.15% senior notes due 2036 and $4 million of our 4.85% senior notes due 2021. Future principal payments due on long-term debt (in millions) as of December 31, 2021, were as follows: 2022$ 300 2023 500 2024 250 2025 300 2026 400 Thereafter 4,581 Total$ 6,331 For our long-term debt outstanding, unsecured senior debt, which consists of senior notes and term loans, ranks highest in priority, followed by subordinated notes and then capital securities. Facility Agreement for Senior Notes Issuance During August 2020, LNC entered into a 10-year facility agreement (the “facility agreement”) with a Delaware trust in connection with the sale by the trust of $500 million of pre-capitalized trust securities in a private placement pursuant to Rule 144A of the Securities Act of 1933, as amended. The trust invested the proceeds from the sale of the trust securities in a portfolio of principal and interest strips of U.S. Treasury securities. The facility agreement provides LNC the right to issue and sell to the trust, on one or more occasions, up to an aggregate principal amount outstanding at any one time of $500 million of LNC’s 2.330% senior notes due August 15, 2030 (“2.330% senior notes”) in exchange for a corresponding amount of U.S. Treasury securities held by the trust. The 2.330% senior notes will not be issued unless and until the issuance right is exercised. In return, LNC pays a semi-annual facility fee to the trust at a rate of 1.691% per year (applied to the unexercised portion of the maximum amount of senior notes that LNC could issue and sell to the trust), and LNC reimburses the trust for its expenses. The issuance right will be exercised automatically in full upon our failure to make certain payments to the trust, such as paying the facility fee or reimbursing the trust for its expenses, if the failure to pay is not cured within 30 days, or upon certain bankruptcy events involving LNC. We are also required to exercise the issuance right in full if our consolidated stockholders’ equity (excluding AOCI) falls below $2.75 billion, subject to adjustment from time to time in certain cases, and upon certain other events described in the facility agreement. Prior to any involuntary exercise of the issuance right, LNC has the right to repurchase any or all of the 2.330% senior notes then held by the trust in exchange for U.S. Treasury securities. LNC may redeem any outstanding 2.330% senior notes, in whole or in part, prior to their maturity. Prior to May 15, 2030, the redemption price will equal the greater of par or a make-whole redemption price. After May 15, 2030, any outstanding 2.330% senior notes may be redeemed at par. Credit Facilities Credit facilities, which allow for borrowing or issuances of letters of credit (“LOCs”), (in millions) were as follows: As of December 31, 2021 Expiration Maximum LOCs Date Available Issued Credit Facilities Five-year revolving credit facilityJune 19, 2026 $ 2,500 $ 15 LOC facility (1)August 26, 2031 983 926 LOC facility (1)October 1, 2031 920 920 Total $ 4,403 $ 1,861 (1)Our wholly-owned subsidiaries entered into irrevocable LOC facility agreements with third-party lenders supporting inter-company reinsurance agreements. During June 2021, we entered into an amended and restated credit agreement with a syndicate of banks, which amended and restated our existing five-year revolving credit facility agreement. The amended credit facility, which is unsecured, allows for the issuance of LOCs and borrowing of up to $2.5 billion and has a commitment termination date of June 19, 2026. The LOCs under the credit facility are used primarily to satisfy reserve credit requirements of (i) our domestic insurance companies for which reserve credit is provided by our affiliated reinsurance companies and (ii) certain ceding companies of our legacy reinsurance business. The amended credit facility agreement contains: Customary terms and conditions, including covenants restricting our ability to incur liens, merge or consolidate with another entity where we are not the surviving entity and dispose of all or substantially all of our assets;Financial covenants including maintenance of a minimum consolidated net worth equal to the sum of $10.0 billion plus 50% of the aggregate net proceeds of equity issuances received by us in accordance with the terms of the agreement; and a debt-to-capital ratio as defined in accordance with the agreement not to exceed 0.35 to 1.00; A cap on secured non-operating indebtedness and non-operating indebtedness of our subsidiaries equal to 7.5% of total capitalization, as defined in accordance with the agreement; and Customary events of default, subject to certain materiality thresholds and grace periods for certain of those events of default. Upon an event of default, the amended credit facility agreement provides that, among other things, the commitments may be terminated and the loans then outstanding may be declared due and payable.  As of December 31, 2021, we were in compliance with all such covenants. Our LOC facility agreements each contain customary terms and conditions, including early termination fees, covenants restricting the ability of the subsidiaries to incur liens, merge or consolidate with another entity and dispose of all or substantially all of their assets. Upon an event of early termination, the agreements require the immediate payment of all or a portion of the present value of the future LOC fees that would have otherwise been paid. Further, the agreements contain customary events of default, subject to certain materiality thresholds and grace periods for certain of those events of default. The events of default include payment defaults, covenant defaults, material inaccuracies in representations and warranties, bankruptcy and liquidation proceedings and other customary defaults. Upon an event of default, the agreements provide that, among other things, obligations to issue, amend or increase the amount of any LOC shall be terminated and any obligations shall become immediately due and payable. As of December 31, 2021, we were in compliance with all such covenants. Shelf Registration We currently have an effective shelf registration statement, which allows us to issue, in unlimited amounts, securities, including debt securities, preferred stock, common stock, warrants, stock purchase contracts, stock purchase units and depository shares.
