The investigation, which began a few months ago, led to Fred Anderson’s resignation, said Cupertino, California-based Apple.

The probe raised serious concerns about the actions of two former unnamed executives with regard to the way stock options grants were recorded, reported and accounted for, said the statement. However, no Apple executive currently serving was found of any misconduct, Apple said.

Chief executive Steve Jobs apologized, in the statement, to shareholders and employees for its accounting problems, which he noted happened on his watch. We will now work to resolve the remaining issues as quickly as possible and to put the proper remedial measures in place to ensure that this never happens again, Jobs said.

Outside auditors are now reviewing the findings of the internal investigation. Apple likely will restate past financial statements as a result, said the company. The amount of charges relating to prior stock option grants, or any resulting changes to its financials, have not yet been determined.
