On March 13, 2023, we executed an amendment to our credit agreement with PNC Bank, National Association (in its capacity as administrative agent, "PNC"), administrative agent for our lenders under our credit agreement, which was accounted for as a debt modification. The primary purpose of the amendment was to convert $35 million of the outstanding balance on the revolver into a new term loan with a maturity of March 31, 2024, and extend the maturity date of the revolver to May 31, 2024. The amendment reduced the total capacity under the revolver to $85 million from $120 million, waived the maximum annual capital expenditure covenant for 2022, and increased the covenant for 2023 to $75 million.

On August 2, 2023, we executed an additional amendment to our credit agreement with PNC, which was accounted for as a debt extinguishment. The primary purpose of the amendment was to convert $65 million of the outstanding funded debt into a new term loan with a maturity of March 31, 2026, and enter into a revolver of $75 million with a maturity of July 31, 2026. The amendment increased the maximum annual capital expenditure limit to $100 million.

Bank debt was reduced by $11.0 million during the six months ended June 30, 2023.  Under the terms of the August 2, 2023 amendment, bank debt is comprised of term debt ($65.0 million as of June 30, 2023) and a $75 million revolver ($9.2 million borrowed as of June 30, 2023).  The term debt requires payments of $3.3 million each quarter commencing in September 2023, increasing to $6.5 million in March 2024 through maturity. Our debt is recorded at amortized cost, which approximates fair value due to the variable interest rates in the agreement, and is collateralized primarily by our assets.

Liquidity

Under the terms of the August 2, 2023 amendment, as of June 30, 2023, we had an additional borrowing capacity of $54.6 million and total liquidity of $56.9 million.  Our additional borrowing capacity is net of $11.2 million in outstanding letters of credit as of June 30, 2023, that were required to maintain surety bonds.  Liquidity consists of our additional borrowing capacity and cash and cash equivalents.

Fees

Unamortized bank fees and other costs incurred in connection with the initial facility and subsequent amendments totaled $2.5 million as of December 31, 2022. Additional costs incurred with the March 13, 2023 amendments totaled $1.6 million.  These costs were deferred and are being amortized over the term of the loan. Unamortized costs as of June 30, 2023, and December 31, 2022, were $1.9 million and $2.5 million, respectively.
