The real estate market downturn continues to batter Thomas Properties Group Inc., which Thursday reported a nearly $6 million loss due to charges related to the declining value of some of its office and mix-used projects.

The Los Angeles real estate company reported a net loss of $5.98 million (-25 cents per share), compared with a net loss of $1.57 million (-7 cents) a year ago. The results include a pre-tax, non-cash impairment charge of $12.2 million related to its Murano condominium project, whose units are complete and held for sale. The company also took a $1.2 million charge related to its joint venture investments.

Revenue fell 10 percent to $7.2 million. After-tax cash flow was $1.22 million (5 cents), compared with $4.03 million (17 cents) a year ago.

“While we are operating in very challenging economic conditions, our properties’ occupancies are relatively strong, rental rates in our markets are holding up, and we do not have significant lease expirations this year,” said Chief Executive Jim Thomas in a statement.

Thomas Properties shares closed up 9 cents, or 6.6 percent, to $1.45 on the Nasdaq.
