The significant change in the fair value of the contingent consideration primarily stemmed from the delay of future new restaurant openings caused by the impact of the COVID-19 pandemic on the estimated cash flows used in the valuation.
The fair values of our cash and cash equivalents, accounts receivable, income taxes receivable, other receivables, prepaid expenses, accounts payable, income taxes payable and other accrued expenses approximate their carrying amounts due to their short duration.
10. Commitments and Contingencies
On June 7, 2018, the California Department of Industrial Relations issued a $4.2 million wage citation jointly against the Company and our vendor that provides janitorial services to 8 of our Southern California restaurants, alleging that the janitorial vendor or its subcontractor failed to comply with various provisions of the California Labor Code (Wage Citation Case No. 35-CM-188798-16). The wage citation seeks to recover penalties and other monetary payments on behalf of the employees that worked for this vendor or its subcontractor. On June 28, 2018, we filed an appeal of the wage citation. On June 11, 2020, the DLSE postponed the hearing on the Company’s appeal due to safety concerns related to the COVID-19 pandemic. It is not possible at this time to reasonably estimate the outcome of or any potential liability from this matter and, accordingly, we have not reserved for any potential future payments.
On June 22, 2018, the Internal Revenue Service issued a Notice of Deficiency in which they disallowed $8.0 million of our §199 Domestic Production Activities Deduction for tax years 2010, 2011 and 2012. On September 11, 2018 we petitioned the United States Tax Court for a redetermination of the deficiency. The tax court has assigned docket number 18150-18 to our case. We intend to vigorously defend our position in litigation and based on our analysis of the law, regulations and relevant facts, we have not reserved for any potential future payments.
Within the ordinary course of our business, we are subject to private lawsuits, government audits and investigations, administrative proceedings and other claims. These matters typically involve claims from customers, staff members and others related to operational and employment issues common to the foodservice industry. A number of these claims may exist at any given time, and some of the claims may be pled as class actions. From time to time, we are also involved in lawsuits with respect to infringements of, or challenges to, our registered trademarks and other intellectual property, both domestically and abroad. We could be affected by adverse publicity and litigation costs resulting from such allegations, regardless of whether they are valid or whether we are legally determined to be liable.
At this time, we believe that the amount of reasonably possible losses resulting from final disposition of any pending lawsuits, audits, investigations, proceedings and claims will not have a material adverse effect individually or in the aggregate on our financial position, results of operations or liquidity. It is possible, however, that our future results of operations for a particular quarter or fiscal year could be impacted by changes in circumstances relating to lawsuits, audits, proceedings or claims. Legal costs related to such claims are expensed as incurred.
11. Stockholders’ Equity and Convertible Preferred Stock
Dividends and Share Repurchases
To preserve liquidity during the COVID-19 pandemic and in conjunction with the terms of our Facility, as amended on May 1,2020 , our Board suspended the quarterly dividend on our common stock, as well as share repurchases. (See Note 7 for further discussion of our long-term debt.)
Future decisions to pay or to increase or decrease dividends on our common stock are at the discretion of the Board and will be dependent on our operating performance, financial condition, capital expenditure requirements, limitations on cash distributions pursuant to the terms and conditions of the Facility and applicable law, and such other factors that our Board considers relevant.
Under authorization by our Board to repurchase up to 56.0 million shares of our common stock, we have cumulatively repurchased 53.0 million shares at a total cost of $1,696.4 million through September 29, 2020 with 12,567 shares repurchased at a cost of $0.4 million during the third quarter of fiscal 2020 to satisfy tax withholding obligations on vested restricted share awards. Our objectives regarding share repurchases have been to offset the dilution to our shares outstanding that results from equity compensation grants and to supplement our earnings per share growth. Our share repurchase authorization does not have an expiration date, does not
