John Coyne is the CEO of OC-based Western Digital, a manufacturer of hard drives, and the company announced this morning that as part of a cost-cutting effort that includes 2,500 layoffs, he and several other senior executives would be reducing their salary. (The OC Register has the story) Instead of a base pay of $900,000 in 2009, Coyne would now make $600,000. A $300,000 pay cut sounds like a nice gesture, but it’s worth noting that in Western Digital's latest proxy statement, Coyne's total compensation in 2007 was $12.6 million. Of that total, $6.1 million went for stock awards and $4.8 million covered non-equity incentive plans. These are not especially outrageous numbers, at least compared with other CEOs, but neither are they insignificant. They speak to a structural disconnect between what CEOs actually make - that is, base salary and perhaps bonus - and what they could potentially reap via stock options and other incentives.
