Shares in Maguire Properties Inc. soared nearly 10 percent Wednesday after the company said it has formed a special committee of independent directors to look into strategic options for the company, including a sale.

Maguire also said in the Tuesday announcement released after markets closed that it is shifting the notice period for shareholder proposals closer to its annual meeting. That move is intended to give more time to the committee evaluating alternatives and interested parties considering making offers.

However, the Los Angeles-based real estate investment trust said that it had not definitively decided to sell itself. Last year, Maguire, downtown L.A’s biggest landlord, explored a sale before withdrawing itself from the market.

Shares in Maguire were up 9.6 percent to $27.69 in early trading Wednesday on the New York Stock Exchange.
