US retailer American Apparel has adopted a so-called 'poison pill' stockholder rights plan - its second this year - which the company says is designed to strengthen the ability of the board to protect its shareholders.

"The board implemented the rights plan as an additional means to ensure that all American Apparel stockholders are treated fairly," the company said in statement yesterday (21 December).

The one-year stockholder rights plan, it added, is designed to limit the ability of any person or group, including recently ousted Dov Charney, to seize control of the company without appropriately compensating all stockholders.

With a 10% trigger, each right will entitle its holder to purchase, for $3.25 per share, a number of shares of the company's common stock or substantially equivalent securities having a market value of twice such price.

This is the second time this year American Apparel has adopted a stockholder rights plan. The first was in June, and was aimed at warding off unwanted takeover attempts as the battle with Charney intensified. 

Last week, American Apparel appointed industry veteran Paula Schneider as its new chief executive, with effect from 5 January.
