Shareholders' Equity	13. Shareholders’ Equity On March 27, 2018, the Company repurchased 1.105 million shares of Class B Common Stock and 0.073 million shares of Common Stock for a combined $146.0 million in a private transaction with the Croatti family at a per share price of $124.00. This opportunity to repurchase shares from the Croatti family was evaluated by an independent special committee of the Board of Directors (the “Special Committee”). The sale of shares by the Croatti family was executed to provide liquidity as well as for estate and family financial planning following the passing of former UniFirst Chief Executive Officer, Ronald D. Croatti. The Special Committee determined that a repurchase of Croatti family Class B Common Stock at a discount to market was in the best interests of the Company as it is accretive to income per share and addresses uncertainties that may have been created if the Croatti family had pursued other liquidity options. The Special Committee undertook its evaluation with the assistance of Stifel Financial Corp. (“Stifel”) and received an opinion from Stifel to the effect that, as of March 27, 2018, the $124.00 per share in cash to be paid was fair to the Company, from a financial point of view. The entire Board of Directors other than Cynthia Croatti, who is affiliated with the selling shareholders and therefore abstained, approved the transaction upon the recommendation of the Special Committee. On March 28, 2018, the Company announced that it would be raising its quarterly dividend to $0.1125 per share for Common Stock and to $0.09 per share for Class B Common Stock, up from $0.0375 and $0.03 per share, respectively. On October 23, 2019, the Company announced that it would be raising its quarterly dividend to $0.25 per share for Common Stock and to $0.20 per share for Class B Common Stock, up from $0.1125 and $0.09 per share, respectively. The amount and timing of any future dividend payment is subject to the approval of the Board of Directors each quarter. The Company has two classes of common stock: Common Stock and Class B Common Stock. Each share of Common Stock is entitled to one vote, is freely transferable, and is entitled to a cash dividend equal to 125% of any cash dividend paid on each share of Class B Common Stock. Each share of Class B Common Stock is entitled to ten votes and can be converted to Common Stock on a share-for-share basis. However, until converted to Common Stock, shares of Class B Common Stock are not freely transferable. For the year ended August 31, 2019, 67,000 shares of Class B Common Stock were converted to Common Stock. On January 2, 2019, the Company’s Board of Directors approved a share repurchase program authorizing the Company to repurchase from time to time up to $100.0 million of its outstanding shares of common stock. Repurchases made under the program, if any, will be made in either the open market or in privately negotiated transactions. The timing, manner, price and amount of any repurchases will depend on a variety of factors, including economic and market conditions, the Company stock price, corporate liquidity requirements and priorities, applicable legal requirements and other factors. The share repurchase program will be funded using the Company’s available cash or capacity under its Credit Agreement and may be suspended or discontinued at any time. During fiscal 2019, the Company repurchased 197,150 shares, respectively, for an average price per share of $154.78.
