Commitments and Contingencies	Commitments and Contingencies Under various Federal, state and local laws, ordinances and regulations relating to the protection of the environment, a current or previous owner or operator of real estate may be liable for the cost of removal or remediation of certain hazardous or toxic substances disposed, stored, generated, released, manufactured or discharged from, on, at, under, or in a property. As such, the Company may be potentially liable for costs associated with any potential environmental remediation at any of its formerly or currently owned properties. The Company conducts Phase I environmental reviews with respect to properties it acquires. These reviews include an investigation for the presence of asbestos, underground storage tanks and polychlorinated biphenyls (PCBs). Although such reviews are intended to evaluate the environmental condition of the subject property as well as surrounding properties, there can be no assurance that the review conducted by the Company will be adequate to identify environmental or other problems that may exist. Where a Phase II assessment is so recommended, a Phase II assessment is conducted to further determine the extent of possible environmental contamination. In all instances where a Phase I or II assessment has resulted in specific recommendations for remedial actions, the Company has either taken or scheduled the recommended remedial action. To mitigate unknown risks, the Company has obtained environmental insurance for most of its properties, which covers only unknown environmental risks. The Company believes that it is in compliance in all material respects with all Federal, state and local ordinances and regulations regarding hazardous or toxic substances. Management is not aware of any environmental liability that it believes would have a material adverse impact on the Company’s financial position or results of operations. Management is unaware of any instances in which the Company would incur significant environmental costs if any or all properties were sold, disposed of or abandoned.

ACADIA REALTY TRUST AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 22. Commitments and Contingencies (continued) The Company is involved in various matters of litigation arising in the normal course of business. While the Company is unable to predict with certainty the amounts involved, the Company’s management and counsel are of the opinion that, when such litigation is resolved, the Company’s resulting liability, if any, will not have a significant effect on the Company’s consolidated financial position, results of operations, or liquidity. The Company's policy is to accrue legal expenses as they are incurred. In September 2008, the Company, certain of its subsidiaries, and other unrelated entities (the “Investor Consortium”) were named as defendants in an adversary proceeding brought by Mervyn's LLC (“Mervyns”) in the United States Bankruptcy Court for the District of Delaware. The action involves five claims alleging fraudulent transfers in which Mervyns is nominally seeking approximately $1.175 billion in damages from the Investor Consortium, although the actual claims made by the administrator and the unsecured creditors are substantially less. The first claim contends that, at the time of the sale of Mervyns by Target Corporation to the Investor Consortium, a transfer of assets was made in an effort to defraud creditors. The Company believes that this aspect of the case is without merit. The remaining four claims relate to transfers of assets of Mervyns at various times after the sale by Target. The Company believes that there are substantial defenses to these claims and intends to continue to defend them vigorously. This matter is in the early stages of discovery. The parties to this action have agreed to a non-binding mediation, which is scheduled for the end of March, 2012. Because of the inherently unpredictable nature of litigation, the Company could incur some amount of liability in connection with this matter. However, at the present time, there have not been sufficient developments in this matter for us to estimate the reasonably possible loss or range of loss that the Company might incur as a result of this matter. During August 2009, the Company terminated the employment of a former Senior Vice President (the “Former Employee”) for engaging in conduct that fell within the definition of “cause” in his severance agreement with the Company. Had the Former Employee not been terminated for “cause,” he would have been eligible to receive approximately $0.9 million under the severance agreement. Because the Company terminated him for “cause,” it did not pay the Former Employee any severance benefits under the agreement. The Former Employee has brought a lawsuit against the Company in New York State Supreme Court, alleging breach of the severance agreement. The suit is in the pre-trial discovery stage. The Company believes it has meritorious defenses to the suit. The Company has arranged for the provision of one letter of credit in connection with a certain lease and investment. As of December 31, 2011, there were no outstanding balances under the letter of credit. If the letter of credit was fully drawn, the combined maximum amount of exposure would be $4.6 million.
