As a result of the filing of the Chapter 11 Cases on March 14, 2019, we have classified unsecured pre-petition liabilities that are expected to be impaired pursuant to the Plan as liabilities subject to compromise in our Condensed Consolidated Balance Sheet at June 30, 2019. Pre-petition liabilities that are subject to compromise are required to be reported at the amounts expected to be allowed, even if they may be settled for lesser amounts. If there was uncertainty at the time of determination about whether a secured claim was under-secured or would be impaired under the Plan, we reflected the entire amount of the claim as an outstanding liability. The amounts classified at June 30, 2019 as liabilities subject to compromise represent the Company’s estimate as of the filing date of this report of claims as of June 30, 2019 expected to be allowed under the Plan.

The Company’s obligations under the Senior Notes have been affected by the bankruptcy filing. As such, the outstanding balance of these Senior Notes and related accrued pre-petition interest have been classified as liabilities subject to compromise in the condensed consolidated balance sheet as of June 30, 2019.

Generally, actions to enforce or otherwise effect payment of pre-bankruptcy filing liabilities have been stayed during the pendency of the Chapter 11 Cases. Although payment of pre-petition claims is generally not permitted, the Bankruptcy Court approved the Debtors’ “first day” motions allowing, among other things, the Company to pay prepetition employee wages and benefits without interruption, maintain its insurance programs, utilize its current cash management system, and pay undisputed prepetition obligations owed to its vendors and trade creditors in the ordinary course of business. As a result of this approval, the Company continues to pay certain pre-petition claims in designated categories and subject to certain terms and conditions in the ordinary course of business, and we have not classified these liabilities as subject to compromise in the Condensed Consolidated Balance Sheet as of June 30, 2019. With respect to pre-petition claims, the Company notified all known claimants of the deadline to file a proof of claim with the Court.

The Company has been paying and intends to continue to pay post-petition claims in the ordinary course of business. The following table reflects pre-petition liabilities that are subject to compromise included in our Condensed Consolidated Balance Sheet as of June 30, 2019.
