Shareholders' Equity [Abstract]
Shareholders' Equity	9. SHAREHOLDERS’ EQUITY Share Repurchases During fiscal 1999, the Board of Directors established the MSC Stock Repurchase Plan (the “Repurchase Plan”). In 2011, the Board of Directors reaffirmed and replenished the Repurchase Plan so that the total number of shares of Class A common stock authorized for future repurchase was 5,000 shares. As of September 1, 2018, the maximum number of shares that may yet be repurchased under the Repurchase Plan was 1,930 shares. The Repurchase Plan allows the Company to repurchase shares at any time and in any increments it deems appropriate in accordance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended. During fiscal years 2018 and 2017, the Company repurchased 972 shares and 685 shares, respectively, of its Class A common stock for $82,369 and $48,869, respectively. 54 and 43 of these shares were repurchased by the Company to satisfy the Company’s associates’ tax withholding liability associated with its share-based compensation program in fiscal years 2018 and 2017, respectively. In July 2018, the Company announced that in connection with its existing share repurchase authorization, the Company had entered into a stock purchase agreement with the holders of the Company’s Class B common stock to purchase a pro rata number of shares, such that their aggregate percentage ownership in the Company would remain substantially the same. In August 2018, the Company purchased 45 shares of its Class A common stock from certain of its Class B shareholders at a purchase price of $82.64 per share. This figure is included in the totals provided in the previous paragraph. All of these shares were immediately retired. Shares of the Company’s common stock purchased pursuant to the stock purchase agreement, as well as shares purchased to satisfy the Company’s associates’ tax withholding liability associated with its share-based compensation program, did not reduce the number of shares that may be repurchased under the Repurchase Plan. The Company reissued 57 shares of treasury stock during both fiscal years 2018 and 2017 to fund the Associate Stock Purchase Plan (see Note 10). Common Stock Each holder of the Company’s Class A common stock is entitled to one vote for each share held of record on the applicable record date on all matters presented to a vote of shareholders, including the election of directors. The holders of Class B common stock are entitled to 10 votes per share for each share held of record on the applicable record date and are entitled to vote, together with the holders of the Class A common stock, on all matters which are subject to shareholder approval. Holders of Class A common stock and Class B common stock have no cumulative voting rights or preemptive rights to purchase or subscribe for any stock or other securities and there are no redemption or sinking fund provisions with respect to such stock. The holders of the Company’s Class B common stock have the right to convert their shares of Class B common stock into shares of Class A common stock at their election and on a one-to-one basis, and all shares of Class B common stock convert into shares of Class A common stock on a one to-one basis upon the sale or transfer of such shares of Class B common stock to any person who is not a member of the Jacobson or Gershwind families or any trust not established principally for members of the Jacobson or Gershwind families or to any person who is not an executor, administrator or personal representative of an estate of a member of the Jacobson or Gershwind families. Preferred Stock The Company has authorized 5,000 shares of preferred stock. The Company’s Board of Directors has the authority to issue the shares of preferred stock. Shares of preferred stock may have priority over the Company’s Class A common stock and Class B common stock with respect to dividend or liquidation rights, or both. As of September 1, 2018, there were no shares of preferred stock issued or outstanding. Cash Dividend In 2003, the Board of Directors instituted a policy of regular quarterly cash dividends to shareholders. This policy is reviewed regularly by the Board of Directors. On October 18, 2018, the Board of Directors declared a quarterly cash dividend of $0.63 per share, payable on November 27, 2018 to shareholders of record at the close of business on November 13, 2018. The dividend will result in a payout of approximately $35,400, based on the number of shares outstanding at October 1, 2018.

9. SHAREHOLDERS’ EQUITY

Share Repurchases

During fiscal 1999, the Board of Directors established the MSC Stock Repurchase Plan (the “Repurchase Plan”). In 2011, the Board of Directors reaffirmed and replenished the Repurchase Plan so that the total number of shares of Class A common stock authorized for future repurchase was 5,000 shares. As of September 1, 2018, the maximum number of shares that may yet be repurchased under the Repurchase Plan was 1,930 shares. The Repurchase Plan allows the Company to repurchase shares at any time and in any increments it deems appropriate in accordance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.

During fiscal years 2018 and 2017, the Company repurchased 972 shares and 685 shares, respectively, of its Class A common stock for $82,369 and $48,869, respectively. 54 and 43 of these shares were repurchased by the Company to satisfy the Company’s associates’ tax withholding liability associated with its share-based compensation program in fiscal years 2018 and 2017, respectively.

In July 2018, the Company announced that in connection with its existing share repurchase authorization, the Company had entered into a stock purchase agreement with the holders of the Company’s Class B common stock to purchase a pro rata number of shares, such that their aggregate percentage ownership in the Company would remain substantially the same. In August 2018, the Company purchased 45 shares of its Class A common stock from certain of its Class B shareholders at a purchase price of $82.64 per share. This figure is included in the totals provided in the previous paragraph. All of these shares were immediately retired.

Shares of the Company’s common stock purchased pursuant to the stock purchase agreement, as well as shares purchased to satisfy the Company’s associates’ tax withholding liability associated with its share-based compensation program, did not reduce the number of shares that may be repurchased under the Repurchase Plan. The Company reissued 57 shares of treasury stock during both fiscal years 2018 and 2017 to fund the Associate Stock Purchase Plan (see Note 10).
