Eastman Kodak said two directors from KKR & Co. resigned from its board, two years after the PE firm helped the 131-year-old company refinance debt.

Adam Clammer and Herald Chen notified the board of their resignation on Dec. 21, Kodak said yesterday. Both were elected in September 2009 after a refinancing deal that included KKR investing in $300 million of senior bonds and warrants for 40 million shares.
