The deal is expected to close in October and ICG will make a profit on the sale, says ICG spokeswoman Susan Koehler, although she declined to say how much.

"As you know the real estate market has risen dramatically in the past few years," Koehler tells GlobeSt.com.

The company occupied the building at 9605 Kingston Ct. from 1993 to 1998.

"We had about 250 employees there in that time," Koehler adds. "We had human resources and our network operations center there. Obviously, in the past year we've had a major consolidation and cost reductions and we had only been using it for miscellaneous purposes. All of our employees had moved into our new headquarters at Interstate 25 and Dry Creek Road."

ICG, in turn, sold its two-year-old, six-story headquarters building to the developer, iStar, for $33 million, Koehler tells GlobeSt.com.

"iStar is some kind of affiliate of Marriott," Koehler says. "We signed a long-term lease with iStar and now are the lead tenant in the building."

The building cost about $43 million, but that would have included an adjacent 1,400-space parking garage.

"When we filed for Chapter 11, we stopped construction on the garage," Koehler says. "iStar is completing the garage. It's a big project. We anticipate it will be finished this winter.
