Acquisition Reserves

We recorded initial acquisition reserves of $47.4 million for restructuring charges and other direct costs associated with the acquisition of Manugistics in 2006. The restructuring charges were primarily related to facility closures, employee severance and termination benefits and other direct costs associated with the acquisition, including investment banker fees, change-in-control payments, and legal and accounting costs. The unused portion of the acquisition reserves at September 30, 2011 includes $5.1 million of current liabilities under the caption "Accrued expenses and other liabilities" and $4.2 million of non-current liabilities under the caption "Accrued exit and disposal obligations." A summary of the charges and adjustments recorded against the reserves is as follows:

The balance in the reserve for office closures, lease termination and sublease costs is primarily related to office facility leases in Rockville, Maryland and the United Kingdom and will be reduced as payments are made over the related lease terms that extend through 2018.

In 2010 in connection with our acquisition of i2, we assumed an unfavorable lease of $1.2 million for the Dallas, Texas office which was recorded in the purchase price allocation at December 31, 2010. As of September 30, 2011, $0.3 million remains in current liabilities under the caption of "Accrued expenses and other liabilities" and $0.4 million remains in non-current liabilities under the caption "Accrued exit and disposal obligations."
