Apple is not alone. According to a recent survey, only 35% of companies have one.

At Apple’s AAPL annual meeting on Feb. 23, shareholders will vote on a proposal that asks the company to produce a written CEO succession plan — a motion that was endorsed Friday by Institutional Shareholder Services, an influential proxy service firm.

All companies should have such a plan in place, ISS said in remarks that were widely reported in the business press.

What ISS should have added is that very few companies do.

According to a December survey of more than 1,300 companies in 60 countries by Korn/Ferry, a leading executive search firm, 98% of respondents agreed that CEO succession planning was an important piece of corporate governance, but only 35% had such a plan in place.

Steve Jobs has often said that he has a plan — which makes sense given his importance to the company and the state of his health — but that he has no intention of making it public.

It’s not likely that he will have to. Shareholder proposals almost never muster enough votes to pass.
