Thomas Properties Group Inc. late Thursday said that it filed a notice with the U.S. Securities and Exchange Commission that it intends to sell up to $30 million in new common stock.

The Los Angeles owner of commercial, residential and mixed-use properties said the shares will be sold at the market price at the time of sale rather than at a fixed price.

Proceeds will be used for general corporate purposes. Cantor Fitzgerald & Co. will be the sales agent for the stock sale.

Thomas Properties in December signed an agreement with some institutional investors to sell 5.14 million shares of its common stock, with proceeds to pay down debt. That transaction produced proceeds of about $13.1 million.

The company last month reported a smaller fourth-quarter net loss on improved revenue from its office properties.

Shares were up 3 cents, or less than 1 percent, to $3.83 in midday trading on the Nasdaq.
