During the second quarter of 2023, we incurred $6.0 million in transaction costs related to the Amended and Restated Credit Agreement, which were included in other assets in our condensed consolidated balance sheets and are being amortized over the remaining term of the Credit Facility. In addition, during the second quarter of 2023, we wrote off $1.0 million of unamortized deferred financing costs as a result of the Amended and Restated Credit Agreement, which was recorded to interest expense in our condensed consolidated statements of operations during the nine months ended September 30, 2023.
As of September 30, 2024, there were $4.1 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.1%. The weighted-average annual interest rate on the outstanding balance under the Credit Facility was 7.2% and 7.7% at September 30, 2024 and December 31, 2023, respectively. We incurred $0.6 million and $0.4 million of commitment fees on the daily unused amount of the Credit Facility during the three months ended September 30, 2024 and 2023, respectively, and $1.5 million and $1.3 million during the nine months ended September 30, 2024 and 2023, respectively.
As of September 30, 2024, we were in compliance with all covenants under our Credit Facility. Additionally, all undrawn capacity on our Credit Facility was available for borrowings as of September 30, 2024.
8. Commitments and Contingencies
Insurance Matters
Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry insurance against some, but not all, risks of our business. Our insurance coverage includes property damage, general liability and commercial automobile liability and other coverage we believe is appropriate. We believe that our insurance coverage is customary for the industry and adequate for our business, however; losses and liabilities not covered by insurance would increase our costs.
Additionally, we are substantially self-insured for workers’ compensation and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. We are also self-insured for property damage to our offshore assets.
Tax Matters
We are subject to a number of state and local taxes that are not income-based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of September 30, 2024 and December 31, 2023, we had $8.9 million and $3.9 million, respectively, accrued for the outcomes of non-income-based tax audits. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We believe the likelihood is remote that the impact of potential unasserted claims from non-income-based tax audits could be material to our consolidated financial position, but it is possible that the resolution of future audits could be material to our consolidated results of operations or cash flows.
As of both September 30, 2024 and December 31, 2023, $0.6 million of the tax contingencies mentioned above related to audits that have advanced from the audit review phase to the contested hearing phase. As of September 30, 2024, $4.3 million of the tax contingencies mentioned above had an offsetting indemnification asset. None were indemnified as of December 31, 2023.
