This excerpt taken from the NDAQ 10-Q filed Nov 9, 2007.
As of September 30, 2007, a current tax asset related to the 2005 sale of Instinets Institutional Brokerage division, related to acquired operating and capital loss carryforwards, was $96.8 million. We and SLP have an agreement to share the tax benefit on the sale of the Institutional Brokerage division. Since the tax benefit increased in the third quarter of 2007, we are required to pay SLP an additional $19.5 million. As such, we recorded a $19.5 million charge in general, administrative and other expense in the Condensed Consolidated Statements of Income. Of the $96.8 million tax benefit, $47.3 million will be paid to SLP. We have recorded a liability for SLPs estimated share of the tax benefit in other accrued liabilities in the Condensed Consolidated Balance Sheets at the present value of the expected payments. We expect to pay SLP $47.3 million in the fourth quarter of 2007.
