When Mayor Richard M. Daley traveled to Abu Dhabi in February, his office announced that the trip was intended to sell Chicago as a place to do business. Left unsaid was that that Persian Gulf emirate was about to become one of the biggest investors in a deal to lease Chicago’s parking meters for 75 years.

The city signed the now-controversial, $1.15 billion lease with a new company called Chicago Parking Meters LLC in February, and city officials said two funds of the Morgan Stanley investment fund made up 99 percent of the new company, with “several other entities” sharing the remaining 1 percent.

In fact, a Chicago News Cooperative investigation has found that investment arms of the oil-rich Abu Dhabi government hold more than a 25 percent stake in the company that privatized the city’s 36,000 parking meters. German financial company Allianz also has a large minority interest, and the remaining 50.1 percent is held by partnerships assembled by Morgan Stanley.

The participation of Abu Dhabi’s sovereign wealth funds and other international investors exposes the level of sophistication of the money behind the city’s parking meter deal. Mayor Daley and other proponents of the contract argue that it is too soon to know if the parking investors will enjoy solid returns, but the players in the Chicago parking company are known for their acumen for profitable long-term deals.
