NEW YORK CITY-Quadra Realty Trust Inc. filed an SEC registration last Thursday to go public. The commercial real estate finance company invests in commercial mortgage investments such as construction loans, mezzanine loans, bridge loans and floating rate whole loans. The filing calls for an estimated $250-million offering amount although it did not specify the number of shares to be sold nor the price range.

In the filing, Quadra says it does not know the effect the sale of common stock would have on the market price of the stock, as these shares have not previously been listed on the stock market. Prior to filing the company had 100 shares of outstanding common stock.

The company, which is filing to be considered a real estate investment trust, is externally managed by Hypo Real Estate Capital Corp. It is unclear how much of a stake the management company will have in the public company--that portion of the SEC filing was left blank. Quadra's investments are generally sourced by the management company, as indicated in the filing.
