Yet more options accounting misery for Apple CEO Steve Jobs this morning, with reports claiming backdated options were used to tempt a top employee to Jobs' former firm, Pixar.

It appears that when Jobs tried to pluck John Lasseter for Pixar, the film director was supplied with a stock options package that was backdated three months before the signing of any employment contract.

The date chosen was that at which Pixar shares had been at their lowest value in the previous year, Marketwatch reports.

The contract was signed by Jobs, it's claimed, though it remains unclear if he was involved in choosing the date.

The information emerges as Disney — in which Jobs is now the single biggest individual shareholder — investigates options accounting practices at the firm.
