Excerpts from KKR’s Q4 2013 Earnings Conference Call held on February 6, 2014

Craig Larson - KKR & Co LP - Head of IR

“. . . on the KFN transaction, please refer to the proxy statement and other SEC filings that KFN and KKR may make because they will contain important information about the transaction.”

“The last area we want to touch on is KFN. We announced the KFN transaction last December, and we are on track for a Q2 close. KFN brings us more permanent capital, more recurring balance sheet income, and more net cash flow to invest behind our ideas and continue to build our firm.”

Bill Katz - Citigroup — Analyst

“When you think about KFN, you may say to be determined, but as you had more time now to study the asset, any update or thoughts around synergies were incremental return potential against those assets?”

Scott Nuttall - KKR & Co LP - Global Head of Capital & Asset Management

“Not much we are able to share incremental to what we shared back in December, Bill, but suffice it to say, we already know the assets quite well because we built the portfolio and have been managing it since 2004. So we like what we are buying, and as you know, we see quite a few opportunities to redeploy that capital into higher returning strategies and ability to seed new businesses for the firm, and that remains the case.”
