A couple of the firms hit hard by last Tuesday’s terrorist attack on the World Trade Center are back to work today.

Specialty investment bank Keefe, Bruyette & Woods, Inc. says that it will resume equity sales and trading today. And Euro Brokers Inc., the inter-dealer subsidiary of Maxcor Financial Group Inc., announced that it had secured new office space and will resume limited business operations immediately.

Euro Brokers was formerly located on the 84th floor at 2 World Trade Center. KBW was on the 88th and 89th floors of the same building.

KBW says that all its orders will be executed from KBW’s existing trading floors in Hartford, Conn.. and Boston. It is also suspending all market making activities in over-the-counter stocks. “Historically, our Hartford and Boston offices have accounted for a significant portion of our overall trading business,” said Thomas Michaud, director of sales & trading. “We have increased staff in these offices, and are confident that we can handle any increased activity.”

KBW has also established temporary offices for its units and divisions at various New York locations. The firm lost 67 of 170 employees in the disaster.

Euro Brokers says its new premises are temporary until a permanent location is decided upon. The space, which is furnished and equipped with phone lines, was made available by Prudential Securities, the parent company of Euro Brokers’ clearing firm, Wexford Clearing Services.

Since Tuesday’s attack on the World Trade Center, 60 of Euro Brokers’ approximately 300 New York-based employees have been reported either as missing or lost.

“Our grief over those of our colleagues and friends who are missing or lost is immeasurable, and our deepest prayers and sympathies go out to their families,” said Gilbert Scharf, Maxcor’s chairman and president. “Resuming our business in the wake of such unimaginable personal losses is certainly not easy, but is the best way we know to rebuild our spirits, stand up against those who attacked us and honor the lives of those we lost.”

Euro Brokers further stated that it has received expressions of support from virtually its entire customer base.

The company emphasized that its historical businesses would be phased back in over a period of time. “Our employees and their families have been through an immense trauma,” said Scharf, “and although our offices will be ready to begin receiving them as of this morning, we have told them to return to work at their own pace.”

The company also reaffirmed its commitment to continue helping the families of those lost or still missing in the World Trade Center attack. Scharf announced that the company will be setting up the Euro Brokers Relief Fund to provide these families with financial assistance in the difficult months and years ahead.
