Distributable Earnings Defined

BGC Partners uses non-GAAP financial measures including “revenues for distributable earnings,” “pre-tax distributable earnings” and “post-tax distributable earnings,” which are supplemental measures of operating performance that are used by management to evaluate the financial performance of the Company and its subsidiaries. BGC Partners believes that distributable earnings best reflect the operating earnings generated by the Company on a consolidated basis and are the earnings which management considers available for distribution to BGC Partners, Inc. and its common stockholders, as well as to holders of BGC Holdings partnership units during any period.

As compared with “income (loss) from operations before income taxes,” “net income (loss) for fully diluted shares,” and “fully diluted earnings (loss) per share,” all prepared in accordance with GAAP, distributable earnings calculations primarily exclude certain non-cash compensation and other expenses which generally do not involve the receipt or outlay of cash by the Company, which do not dilute existing stockholders, and which do not have economic consequences, as described below. In addition, distributable earnings calculations exclude certain gains and charges that management believes do not best reflect the ordinary operating results of BGC.

Revenues for distributable earnings are defined as GAAP revenues excluding the impact of BGC Partners, Inc.’s non-cash earnings or losses related to its equity investments, such as in Aqua Securities, L.P. and ELX Futures, L.P., and its holding company general partner, ELX Futures Holdings LLC. Revenues for distributable earnings include the collection of receivables which would have been recognized for GAAP other than for the effect of acquisition accounting. Revenues for distributable earnings also exclude certain one-time or unusual gains that are recognized under GAAP, because the Company does not believe such gains are reflective of its ongoing, ordinary operations.

Pre-tax distributable earnings are defined as GAAP income (loss) from operations before income taxes excluding items that are primarily non-cash, non-dilutive, and non-economic, such as:

Distributable earnings calculations also exclude charges related to purchases, cancellations or redemptions of partnership interests and certain unusual, one-time or non-recurring items, if any.

“Compensation and employee benefits” expense for distributable earnings will also include broker commission payouts relating to the aforementioned collection of receivables.

BGC’s definition of distributable earnings also excludes certain gains and charges with respect to acquisitions, dispositions, and resolutions of litigation. This exclusion pertains to the expected one-time cash payment of $750 million, before taxes, related to the expected NASDAQ OMX transaction. Management believes that excluding these gains and charges best reflects the operating performance of BGC. However, because NASDAQ OMX is expected to pay BGC in an equal amount of stock on a regular basis for 15 years as part of this expected deal, the payments associated with BGC’s receipt of such stock will be included in the Company’s calculation of distributable earnings.

Since distributable earnings are calculated on a pre-tax basis, management intends to also report “post-tax distributable earnings” and “post-tax distributable earnings per fully diluted share”:

BGC’s distributable earnings per share calculations assume either that:

Each quarter, the dividend to common stockholders is expected to be determined by the Company’s Board of Directors with reference to post-tax distributable earnings per fully diluted share. In addition to the Company’s quarterly dividend to common stockholders, BGC Partners expects to pay a pro-rata distribution of net income

to BGC Holdings founding/working partner and other limited partnership units, including REUs, RPUs, LPUs, PSUs and PSIs, and to Cantor for its noncontrolling interest. The amount of all of these payments is expected to be determined using the above definition of pre-tax distributable earnings per share.

Certain employees who are holders of RSUs are granted pro-rata payments equivalent to the amount of dividends paid to common stockholders. Under GAAP, a portion of the dividend equivalents on RSUs is required to be taken as a compensation charge in the period paid. However, to the extent that they represent cash payments made from the prior period’s distributable earnings, they do not dilute existing stockholders and are therefore excluded from the calculation of distributable earnings.

Distributable earnings is not meant to be an exact measure of cash generated by operations and available for distribution, nor should it be considered in isolation or as an alternative to cash flow from operations or GAAP net income (loss). The Company views distributable earnings as a metric that is not necessarily indicative of liquidity or the cash available to fund its operations.

Pre- and post-tax distributable earnings are not intended to replace the Company’s presentation of GAAP financial results. However, management believes that they help provide investors with a clearer understanding of BGC Partners’ financial performance and offer useful information to both management and investors regarding certain financial and business trends related to the Company’s financial condition and results of operations. Management believes that distributable earnings and the GAAP measures of financial performance should be considered together.

Management does not anticipate providing an outlook for GAAP “revenues,” “income (loss) from operations before income taxes,” “net income (loss) for fully diluted shares,” and “fully diluted earnings (loss) per share,” because the items previously identified as excluded from pre-tax distributable earnings and post-tax distributable earnings are difficult to forecast. Management will instead provide its outlook only as it relates to revenues for distributable earnings, pre-tax distributable earnings and post-tax distributable earnings.
