Current maturities of long-term debt include an accreting zero-coupon note that may be redeemed each May, until maturity in 2022. If the zero-coupon note (issued for principal of $500 in 2007 and partially exchanged in the 2017 debt exchange offers) is held to maturity, the redemption amount will be $592.

In September 2019, we entered into and drew on a $1,300 term loan credit agreement containing (i) a 1.25 year $400 facility due in 2020, (ii) a 2.25 year $400 facility due in 2021, and (iii) a 3.25 year $500 facility due in 2022, with Bank of America, N.A., as agent. These facilities were repaid and terminated in the second quarter of 2020.

In April 2020, we entered into and drew on a $5,500 Term Loan Credit Agreement (Term Loan) with 11 commercial banks and Bank of America, N.A. as lead agent. We repaid and terminated the Term Loan in May 2020.

On January 29, 2021, we entered into a $14,700 Term Loan Credit Agreement (Term Loan), with Bank of America, N.A., as agent. The Term Loan is available for a single draw at any time before May 29, 2021. The proceeds will be used for general corporate purposes, which may include among other things, financing acquisitions of additional spectrum. The entire principal amount of the Term Loan will be due and payable 364 days after the date on which the borrowing is made. At January 31, 2021, we had approximately $6,100 of commercial paper outstanding.

In November 2020, we amended one of our $7,500 revolving credit agreements by extending the termination date. In total, we have two $7,500 revolving credit agreements, totaling $15,000, with one terminating on December 11, 2023 and the other terminating on November 17, 2025. No amounts were outstanding under either agreement as of December 31, 2020.

Each of the credit agreements contains covenants that are customary for an issuer with an investment grade senior debt credit rating, as well as a net debt-to-EBITDA (earnings before interest, taxes, depreciation and amortization, and other modifications described in each agreement) financial ratio covenant requiring AT&T to maintain, as of the last day of each fiscal quarter, a ratio of not more than 3.5-to-1. The events of default are customary for agreements of this type and such events would result in the acceleration of, or would permit the lenders to accelerate, as applicable, required payments and would increase each agreement’s relevant Applicable Margin by 2.00% per annum.

The obligations of the lenders under two revolving credit agreements to provide advances will terminate on December 11, 2023, and November 17, 2025, unless the commitments are terminated in whole prior to that date. All advances must be repaid no later than the date on which lenders are no longer obligated to make any advances under the applicable credit agreement.

Each of the credit agreements provides that we and lenders representing more than 50% of the facility amount may agree to extend their commitments under such Credit Agreement for two one-year periods beyond the initial termination date. We have the right to terminate, in whole or in part, amounts committed by the lenders under each of the credit agreements in excess of any outstanding advances; however, any such terminated commitments may not be reinstated.
