NASDAQ OMX Group (NDAQ)

U.S. Cash Equity Trading

U.S. cash equity trading revenues are variable, based on service volumes, and recognized as transactions occur. We charge transaction fees for executing cash equity trades in NASDAQ-listed and other listed securities on The NASDAQ Stock Market as well as on orders that are routed to other market venues for execution.

We credit a portion of the per share execution charge to the market participant that provides the liquidity and record the liquidity rebate as a cost of revenues in the Consolidated Statements of Income. These liquidity rebates are paid on a monthly basis and the amounts due are included in accounts payable and accrued expenses in the Consolidated Balance Sheets. Also, we pay Section 31 fees to the SEC for supervision and regulation of securities markets. We pass these costs along to our customers through our cash equity trading fees. We collect the fees as a pass-through charge from organizations executing eligible trades on The NASDAQ Stock Market platform and we recognize these amounts in cost of revenues when invoiced. Section 31 fees received are included in cash and cash equivalents in the Consolidated Balance Sheets at the time of receipt and, as required by law, the amount due to the SEC is remitted semiannually and recorded as Section 31 fees payable to the SEC in the Consolidated Balance Sheets until paid. Since the amount recorded in revenues is equal to the amount recorded in cost of revenues, there is no impact on our revenues less liquidity rebates, brokerage, clearance and exchange fees. As we hold the cash received until payment to the SEC, we earn interest income on the related cash balances.

We closed the acquisition of BSX in August 2008. We used the BSX license to create a second U.S. cash equities market, called NASDAQ OMX BX, which was launched in January 2009. With NASDAQ OMX BX, we offer a second quote within the U.S. equities marketplace, providing our customers enhanced trading choices and price flexibility. We expect to generate revenues for executing cash equity trades on NASDAQ OMX BX in the same manner as we do for trading on The NASDAQ Stock Market.

In the U.S., pursuant to EITF 99-19, we record execution revenues from transactions on a gross basis in revenues and record related expenses as cost of revenues. Nasdaq Execution Services, which is registered with the SEC as a broker-dealer, operates as The NASDAQ Stock Market’s routing broker-dealer for sending orders to other venues for execution in accordance with member order instructions and requirements. Nasdaq Execution Services, which is registered with the SEC as a broker-dealer, also clears all trading activity directly with the NSCC, either as a Qualified Special Representative, or QSR, or under an Automated Give Up, or AGU, agreement, through Automated Confirmation Trades system, or ACT, except for institutional trades and Designated Order Turnaround, or DOT, processed listed securities. The QSR relationship is an agreement between Nasdaq Execution Services, the clearing broker and a contra-clearing broker whereby the contra-clearing broker agrees to honor all trades sent directly to the NSCC by Nasdaq Execution Services. In the AGU relationship, Nasdaq Execution Services will send the trade to ACT initially and then ACT will send the trade to the NSCC for clearing. Nasdaq Execution Services, as a broker-dealer, can also receive non-electronic executions from markets that experienced technical issues hindering the receipt of electronic executions on trade date. These executions not received electronically on trade date (T) could be received in clearing on T+1 where Nasdaq Execution Services could potentially need to trade out of these executions on a principal capacity basis.

Under our Limitation of Liability Rule and procedures, we, subject to certain caps, provide compensation for losses directly resulting from the systems’ actual failure to correctly process an order, Quote/Order, message or other data into our platform. We do not record a liability for any potential claims that may be submitted under the Limitation of Liability Rule unless they meet the provisions of SFAS No. 5, “Accounting for Contingencies,” or SFAS 5. As such, losses arising as a result of the rule are accrued and charged to expense only if the loss is probable and estimable. The Limitation of Liability Rule and procedures applies to both U.S. cash equity and U.S. derivative trading in the aggregate. See discussion of U.S. derivative trading below.
