Litigation and Other Contingencies Litigation Chapter 11 Proceedings On May 15, 2020, the Debtors filed the Chapter 11 Cases seeking relief under the Bankruptcy Code. The Company expects to continue operations in the normal course for the duration of the Chapter 11 Cases. In addition, subject to certain exceptions under the Bankruptcy Code, the filing of the Debtors' Chapter 11 Cases also automatically stayed the filing of most legal proceedings and other actions against or on behalf of the Debtors or their property to recover on, collect or secure a claim arising prior to the Petition Date or to exercise control over property of the Debtors' bankruptcy estates, unless and until the Bankruptcy Court modifies or lifts the automatic stay as to any such claim. See Note 14 for more information about the Chapter 11 Cases. Shareholder Derivative Litigation and Demand On October 19, 2018, a shareholder of the Company, Juan Rojas, filed a shareholder derivative action against certain present and former members of the Companys Board of Directors in the Delaware Court of Chancery. The Company was named as a nominal defendant. The lawsuit asserted claims for breaches of fiduciary duties based on alleged failures to prevent the Company from engaging in allegedly unlawful promotional pricing practices. On July 29, 2019, the Court granted defendants' motion to dismiss and dismissed plaintiffs complaint with prejudice. On October 21, 2019, the Companys Board of Directors received a demand from Rojas to conduct an investigation of alleged breaches of fiduciary duties similar to those made in the dismissed derivative action regarding alleged failures to prevent the Company from engaging in allegedly unlawful promotional pricing practices. The Board of Directors appointed a committee of independent directors (the "Demand Review Committee") to review the demand and make a recommendation to the Board of Directors regarding a response to the demand. In May 2020, the Demand Review Committee completed its review and recommended that the demand be denied, which recommendation was adopted by the Board of Directors. While no assurance can be given as to the ultimate outcome of this matter, we believe that the final resolution of this action will not have a material adverse effect on our results of operations, financial position, liquidity or capital resources. Other Legal Proceedings We are subject to various other legal and governmental proceedings involving routine litigation incidental to our business. Accruals have been established based on our best estimates of our potential liability in certain of these matters, which we believe aggregate to an amount that is not material to the unaudited Interim Consolidated Financial Statements. These estimates were developed in consultation with in-house and outside counsel. While no assurance can be given as to the ultimate outcome of these matters, we currently believe that the final resolution of these actions, individually or in the aggregate, will not have a material adverse effect on our results of operations, financial position, liquidity or capital resources. Contingencies As of May 2, 2020, we have an estimated accrual of $19 million related to potential environmental liabilities that is recorded in Other accounts payable and accrued expenses and Other liabilities in the unaudited Interim Consolidated Balance Sheet. This estimate covered potential liabilities primarily related to underground storage tanks and remediation of environmental conditions involving our former drugstore locations. We continue to assess required remediation and the adequacy of environmental reserves as new information becomes available and known conditions are further delineated. If we were to incur losses at the estimated amount, we do not believe that such losses would have a material effect on our financial condition, results of operations, liquidity or capital resources.
