LONDON (Reuters) - U.S. hedge fund Elliott Management Corp acquired derivatives equivalent to a stake of almost 11 percent in UK-based F&C Asset Management (>> F&C Asset Management plc), a filing showed on Wednesday.

The activist hedge fund purchased derivatives equivalent to around 63.8 million ordinary shares, the filing showed.

A spokesman for F&C declined to comment while Elliott could not immediately be reached.

In January, Bank of Montreal (>> Bank of Montreal) struck a deal to buy F&C for 708 million pounds.

F&C's second largest shareholder, Standard Life Investments, said at the time the deal represented an "attractive valuation" of the asset manager for the Canadian bank and it may support a rival bid if one emerges.

Standard Life Investments declined to comment.
