THE MONEY: Veteran developer took some hits. Maguire is underwater on his most valuable property, 900-acre Solana business park in Texas, and has yet to benefit from natural gas partnership in state’s Barnett Shale field. Maguire provided the valuation, which may be generous.

BUZZ: Not all bad news for man who developed L.A.’s tallest high-rise, now called U.S. Bank Tower. Announced he is talking with L.A. Live developer AEG to build downtown’s first high-rise in two decades. In January, sold his 901 Airole Way home to actress Jennifer Aniston for $21 million. Also has put his two largest L.A. properties, including his Santa Monica headquarters, on the market. Main problem is $340 million loan in special servicing on Solana. Is still trying to work out deal to avoid foreclosure. Four years ago, he was ousted from his Maguire Properties, now known as MPG Office Trust Inc., after ill-advised expansion just prior to real estate bust. Still retains stake in company, which has downtown trophy buildings in its portfolio. His Maguire Aviation remains the largest lease holder at Van Nuys Airport. A pilot himself, Maguire had a father who flew Jewish refugees to Israel after WWII.
