Eastman Kodak has filed for Chapter 11 bankruptcy protection. The company's backers include Kohlberg Kravis Roberts, which invested $300 million through a senior secured notes offering by Kodak in 2009. The company has obtained a $950 million credit facility from Citigroup to allow operations to continue during the bankruptcy. Lazard and FTI Consulting are advising Kodak, while Sullivan & Cromwell are providing legal counsel. .
