CoreLogic (CLGX) Chief Financial Officer Anthony "Buddy" Piszel resigned this week following a notice sent to him by the Securities and Exchange Commission regarding disclosure matters while he was employed at Freddie Mac. Piszel told CoreLogic that he received a Wells notice from the SEC that warned him of possible civil enforcement action against him. Under SEC procedures, Piszel has the ability to respond in an attempt to persuade the regulator that no action should be taken. CoreLogic said he intends to do so. The SEC notice refers to actions Piszel took when he served as financial head of Freddie Mac from November 2006 to September 2008. He joined CoreLogic in January 2009, and will stay on as a nonexecutive through June 1, to help with the transition. Michael Rasic, CoreLogic senior vice president of finance and accounting, will serve as principal financial officer while the company looks for a replacement. "While we appreciate Buddy’s contributions during his tenure at CoreLogic, after careful consideration of these developments, our board of directors, Buddy and I decided it would be in the best interest of the company for Buddy to leave CoreLogic to focus on his response to these issues," CoreLogic CEO Anand Nallathambi said.
