Apple Inc CEO Tim Cook earned roughly the same in 2013 as in 2012, but lost part of his performance-based stock award during a year in which intense competition and margin pressure bludgeoned the iPhone maker's stock.

Cook took home $4.25 million, including a base salary of $1.4 million and a performance bonus of $2.8 million, roughly on par with 2012, the company said in a preliminary proxy statement on Friday.

But he gave up about 7,100 shares tied to an annual performance-dependent award, based on shareholder returns from August 24 of 2012 to August 25, 2013. Apple's stock lost a quarter of its value over that one-year period.

The company also advised shareholders to vote down a resolution by activist investor Carl Icahn, who proposed the iPhone maker buy back $50 billion worth of shares in fiscal 2014. It was the first time the company had publicly voiced its response to Icahn's demands.
