Recapitalization and Post‑IPO Capital Structure

Immediately prior to and immediately following the consummation of the IPO, IBG, Inc., Holdings, IBG LLC and the members of IBG LLC consummated a series of transactions collectively referred to herein as the “Recapitalization.” In connection with the Recapitalization, IBG, Inc., Holdings and the historical members of IBG LLC entered into an exchange agreement, dated as of May 3, 2007 (the “Exchange Agreement”), pursuant to which the historical members of IBG LLC received membership interests in Holdings in exchange for their membership interests in IBG LLC. Additionally, IBG, Inc. became the sole managing member of IBG LLC.

In connection with the consummation of the IPO, Holdings used the net proceeds to redeem 10.0% of members’ interests in Holdings in proportion to their interests. Immediately following the Recapitalization and IPO, Holdings owned approximately 90% of IBG LLC and 100% of IBG, Inc.’s Class B common stock, which has voting power in IBG, Inc. in proportion to Holdings’ ownership of IBG LLC.

Since consummation of the IPO and Recapitalization, IBG, Inc.’s equity capital structure has been comprised of Class A and Class B common stock. All shares of common stock have a par value of $0.01 per share and have identical rights to earnings and dividends and in liquidation. As of June 30, 2016 and December 31, 2015, 1,000,000,000 shares of Class A common stock were authorized, of which 66,516,360 and 64,121,150 shares have been issued; and 65,671,645 and 63,985,335 shares were outstanding, respectively. Class B common stock is comprised of 100 authorized shares, of which 100 shares were issued and outstanding as of June 30, 2016 and December 31, 2015, respectively. In addition, 10,000 shares of preferred stock have been authorized, of which no shares are issued or outstanding as of June 30, 2016 and December 31, 2015, respectively.

As a result of a federal income tax election made by IBG LLC applicable to the acquisition of IBG LLC member interests by IBG, Inc., the income tax basis of the assets of IBG LLC acquired by IBG, Inc. have been adjusted based on the amount paid for such interests. Deferred tax assets were recorded as of the IPO date and in connection with subsequent redemptions of Holdings member interests in exchange for common stock. These deferred tax assets are included in other assets in the Company’s condensed consolidated statements of financial condition and are being amortized as additional deferred income tax expense over 15 years from the IPO date and from the additional redemption dates, respectively, as allowable under current tax law. As of June 30, 2016 and December 31, 2015, the unamortized balance of these deferred tax assets was $275 million and $288 million, respectively.

IBG, Inc. also entered into an agreement (the “Tax Receivable Agreement”) with Holdings to pay Holdings (for the benefit of the former members of IBG LLC) 85% of the tax savings that IBG, Inc. actually realizes as the result of tax basis increases. These payables to Holdings are reported as payable to affiliate in the Company’s condensed consolidated statements of financial condition. The remaining 15% is accounted for as a permanent increase to additional paid‑in capital in the Company’s condensed consolidated statements of financial condition.

The cumulative amounts of deferred tax assets, payables to Holdings and additional paid‑in capital arising from stock offerings from the date of the IPO through June 30, 2016 were $460 million, $391 million and $69 million, respectively. Amounts payable under the Tax Receivable Agreement are payable to Holdings annually following the filing of IBG, Inc.’s federal income tax return. The Company has paid Holdings a cumulative total of $116 million through June 30, 2016 pursuant to the terms of the Tax Receivable Agreement.

The Exchange Agreement, as amended, provides for future redemptions of member interests and for the purchase of member interests in IBG LLC by IBG, Inc. from Holdings, which could result in IBG, Inc. acquiring the remaining member interests in IBG LLC that it does not own. On an annual basis, members of Holdings are able to request redemption of their interests.

At the time of IBG, Inc.’s IPO in 2007, three hundred sixty (360) million shares of authorized common stock were reserved for future sales and redemptions. From 2008 through 2010, Holdings redeemed 5,013,259 IBG LLC interests with a total value of $114 million, which redemptions were funded using cash on hand at IBG LLC. Upon cash redemption these IBG LLC interests were retired. From 2011 through 2015, IBG, Inc. issued 11,047,295 shares of common stock (with a fair value of $306 million) directly to Holdings in exchange for an equivalent number of member interests in IBG LLC.

As a consequence of these redemption transactions, and distribution of shares to employees (see Note 9), IBG, Inc.’s interest in IBG LLC has increased to approximately 16.2%, with Holdings owning the remaining 83.8% as of June 30, 2016. The redemptions also resulted in an increase in the Holdings interest held by Mr. Thomas Peterffy and his affiliates from approximately 84.6% at the IPO to approximately 88.7% as of June 30, 2016.

On July 28, 2016, the Company filed a Supplemental Prospectus on Form 424B5 (File Number 333-192275) with the SEC to issue 1,596,200 shares of common stock in exchange for an equivalent number of shares of member interests in IBG LLC. This issuance of shares increased the Company’s ownership in IBG LLC from 16.2% to 16.6%.
