1	Borrowings on the bank line of credit and commercial paper are classified as short-term if we intend to repay within twelve months and as long-term if we have the intent and ability to extend payment beyond twelve months.
2	The effective interest rate excludes the impact of the interest rate swap described in Note 6.
3	See Note 6 for additional information on our fair value hedging strategy.

Discounts and debt issuance costs are amortized using the effective interest method over the terms of the respective notes resulting in $3.7 million and $2.4 million of net interest expense for these items for the six months ended June 30, 2023 and 2022, respectively.

DELAYED DRAW TERM LOAN, LINE OF CREDIT AND COMMERCIAL PAPER PROGRAM

In June 2021, we entered into a $1,600.0 million unsecured delayed draw term loan which was fully drawn in August 2021 upon the acquisition of U.S. Concrete. The delayed draw term loan was paid down to $1,100.0 million in September 2021 with cash on hand, paid down to $550.0 million in August 2022 using the proceeds from the issuance of commercial paper as described below and fully repaid in March 2023 using proceeds from the issuance of 5.80% senior notes as described below.

Our unsecured line of credit was amended in August 2022 to increase the borrowing capacity from $1,000.0 million to $1,600.0 million and extend the maturity date from September 2026 to August 2027. Our line of credit contains covenants customary for an unsecured investment-grade facility. As of June 30, 2023, we were in compliance with the covenants.

Borrowings on the line of credit bear interest, at our option, at either SOFR plus a margin ranging from 1.000% to 1.625% or Truist Bank’s base rate (generally, its prime rate) plus a margin ranging from 0.000% to 0.625%. The margins are determined by our credit ratings. Standby letters of credit, which are issued under the line of credit and reduce availability, are charged a fee equal to the margin for SOFR borrowings plus 0.175%. We also pay a commitment fee on the daily average unused amount of the line of credit that ranges from 0.090% to 0.225% determined by our credit ratings. As of June 30, 2023, the margin for SOFR borrowings was 1.125%, the margin for base rate borrowings was 0.125% and the commitment fee for the unused amount was 0.100%.

In August 2022, we established a $1,600.0 million commercial paper program through which we borrowed $550.0 million that was used to partially repay the delayed draw term loan. Commercial paper borrowings bear interest at rates determined at the time of borrowing and as agreed between us and the commercial paper investors.

As of June 30, 2023, our available borrowing capacity under the line of credit was $1,516.8 million. Utilization of the borrowing capacity was as follows:

None was borrowed

$83.2 million was used to support standby letters of credit

TERM DEBT

All of our $3,941.6 million (face value) of term debt (which includes the $550.0 million commercial paper) is unsecured. All of the covenants in the debt agreements are customary for investment-grade facilities. As of June 30, 2023, we were in compliance with all term debt covenants.

In March 2023, we issued $550.0 million of 5.80% senior notes due 2026. Total proceeds of $546.6 million (net of discounts and transaction costs), together with cash on hand, were used to repay the $550.0 million delayed draw term loan.

STANDBY LETTERS OF CREDIT

We provide, in the normal course of business, certain third-party beneficiaries with standby letters of credit to support our obligations to pay or perform according to the requirements of an underlying agreement. Such letters of credit typically have an initial term of one year, renew automatically and can only be modified or canceled with the approval of the beneficiary. Our standby letters of credit are issued by banks that participate in our $1,600.0 million line of credit and reduce the borrowing capacity thereunder. Our standby letters of credit as of June 30, 2023 are summarized by purpose in the table below:

in millions
Standby Letters of Credit
Risk management insurance	$          74.5
Reclamation/restoration requirements	8.7
Total	$          83.2
