Common Stock	14. Common Stock CBIZ’s authorized common stock consists of 250 million shares of common stock, par value $0.01 per share (“Common Stock”). The holders of CBIZ’s Common Stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. There are no cumulative voting rights with respect to the election of directors. Accordingly, the holder or holders of a majority of the outstanding shares of Common Stock will be able to elect the directors of CBIZ then standing for election as terms expire. Holders of Common Stock have no preemptive rights and are entitled to such dividends as may be declared by the Board of Directors of CBIZ out of funds legally available. The holders of CBIZ’s Common Stock are not entitled to any sinking fund, redemption or conversion rights. On liquidation, dissolution or winding up of CBIZ, the holders of Common Stock are entitled to share ratably in the net assets of CBIZ remaining after the payment to any and all creditors. The outstanding shares of Common Stock are duly authorized, validly issued, fully paid and non-assessable. In 2006, CBIZ filed a registration statement with the SEC to register an undeterminable number of shares of Common Stock issuable by the Company upon conversion (the “Conversion Shares”) of the Company’s issued and outstanding 2006 Notes. The registration statement was declared effective on August 4, 2006. In September 2010 and June 2011, $60 million and $39.3 million, respectively, of the 2006 Notes were retired by CBIZ, leaving $750,000 outstanding as of December 31, 2013. Although the Company cannot at this time determine the number of Conversion Shares it will issue upon conversion of the remaining 2006 Notes, if any, the number of Conversion Shares will be calculated as set out in the S-3 Registration Statement filed by the Company with the SEC on July 21, 2006. In addition, in September 2010, CBIZ issued the 2010 Notes pursuant to Rule 144A of the Securities Act of 1933, as amended. The Company cannot at this time determine the number of shares of Common Stock it will issue upon conversion of these notes, although the number of shares of Common Stock it will issue, if any, will be calculated as defined in the indenture agreements with U.S. Bank National Association as trustee. The 2006 Notes and 2010 Notes are further discussed in Note 8. Treasury Stock CBIZ’s Board of Directors approved various share repurchase programs that were effective during the years ended December 31, 2013, 2012 and 2011. Under these programs, shares may be purchased in the open market or in privately negotiated transactions according to SEC rules. The repurchase programs do not obligate CBIZ to acquire any specific number of shares and may be suspended at any time. Repurchased shares are held in treasury and may be reserved for future use in connection with acquisitions, employee share plans and other general purposes. Under CBIZ’s amended credit facility (described in Note 8), there are no limitations on CBIZ’s ability to repurchase CBIZ Common Stock provided that the Senior Leverage Ratio, as defined by the credit facility, is less than 2.0. On September 14, 2010, CBIZ’s Board of Directors authorized a supplemental share repurchase program allowing for an additional 7,716,669 shares of CBIZ’s Common Stock to be repurchased from CBIZ’s largest shareholder at that time, Westbury, a company organized by CBIZ founder Michael G. DeGroote. In addition, on September 16, 2010, CBIZ’s Board of Directors authorized a second supplemental repurchase program allowing for an additional 4,578,894 shares of CBIZ’s Common Stock to be repurchased using a portion of the proceeds from the 2010 Notes transaction. The total cost of these two share repurchases was $48.5 million and $25.1 million for the Westbury and 2010 Notes transactions, respectively. On August 30, 2013, concurrent with the sale of MMP, CBIZ repurchased an additional 3.85 million shares from Westbury, which was 50% of Westbury’s then current holdings of the Company’s common stock, at a price of $6.65 per share, which represented the 60-day moving average share price at July 1, 2013. The total cost of this repurchase was $25.7 million. See Note 18 for further discussion of the Westbury transactions. Not including the shares repurchased from the 2010 supplemental share repurchase plans as well as the shares repurchased from Westbury in 2013 as discussed above, CBIZ repurchased 1.0 million shares under the share repurchase programs during each of the years ended December 31, 2012 and 2011, at a cost (including fees and commissions) of $5.7 million and $9.5 million, respectively. No shares were repurchased in 2013.
