SAN FRANCISCO, CA -- February 10, 2005 – ABM Industries Incorporated (NYSE: ABM) announced today that the United States Court of Appeals for the Second Circuit had granted summary judgment in favor of ABM on the Company’s insurance claims for business interruption losses resulting from the World Trade Center (WTC) disaster.

The Appeals Court also ruled that ABM is entitled to recovery for the extra expenses it incurred after 9/11, which include millions of dollars related to increased unemployment claims and costs associated with the redeployment of WTC personnel at other facilities. The Appeals Court rejected the arguments of Zurich American Insurance Co. (Zurich) to limit ABM’s business interruption coverage and returned the case to the Southern District of New York for determination of appropriate additional compensation under the policy.

“We are very pleased with the Court’s ruling,” said Linda S. Auwers, ABM Senior Vice President & General Counsel. “Since the Court of Appeals has established our business interruption coverage and ruled on several of the case’s central issues, we look forward to a fair and timely resolution of our claims with Zurich.”

ABM will continue to pursue its claims against Zurich. Under the policy, coverage for ABM’s business interruption and other related losses is capped at $127 million. ABM believes its losses exceed $100 million.

ABM had commercial insurance policies with Zurich covering business interruption, property damage and other losses related to the WTC complex. At the time, the WTC was the Company’s largest single job-site with annual sales of approximately $75.0 million (3% of the Company’s consolidated sales for 2001).

In December 2001, Zurich filed a Declaratory Judgment Action in the Southern District of New York claiming the loss of the business profit fell under the policy’s contingent business interruption sub-limit of $10 million. On June 2, 2003, the court ruled on certain summary judgment motions in favor of Zurich. Subsequent to the June 2003 ruling, additional rulings by the court limited ABM’s recourse under the policy to the amounts paid plus additional amounts related to physical property and financial records of the Company located on the WTC premises.

As of October 31, 2004, Zurich had paid ABM two partial settlements totaling $13.8 million, of which $10.0 million was for business interruption under the contingent business interruption sub-limit and $3.8 million for property damage, which substantially settled the property portion of the claim.
