Don't worry — offices aren't doomed

Gas Company Tower was once a gleaming model of downtown America's ascendancy. Located squarely in Los Angeles' central business district, the 52-story skyscraper has a strong pedigree. It's home to a collection of major corporate tenants, including the Southern California Gas Company, the white-shoe law firm Sidley Austin, and Deloitte, one of the Big Four accounting firms. Its owner, Brookfield, is an $800 billion investment firm known for its blue-chip portfolio of real-estate assets. The tower's lobby even had a Hollywood cameo when it was featured in the opening shot of the 1994 film "Speed."

More recently, though, the glassy office property has become an example of the alarming financial turmoil that is engulfing once-bedrock real-estate assets. Brookfield disclosed in a February filing that a subsidiary it controls had defaulted on $753.9 million worth of debt tied to the tower and another nearby office building — one of the largest since the great financial crisis. But as Brookfield grapples with its lenders, it's also facing a potential exodus of the building's most visible occupants.
