Herbert Smith Freehills is acting for the Commonwealth Bank of Australia in the sale of a half share of its wealth management unit to private equity giant KKR.

CBA announced last week it is selling a 55% interest in Colonial First State (CFS) to KKR for A$1.7 billion (US$1.1 billion).

HSF has confirmed its role for CBA. KKR is being represented by the Australian firm Gilbert + Tobin, according to the Australian Financial Review. Gilbert + Tobin did not respond to requests for comment.

The sale forms part of CBA's strategy to focus on its core banking businesses, CBA said in a statement.

"Together, CBA and KKR intend to undertake a significant investment program, strengthening the position of CFS as one of Australia's leading retail superannuation and investments businesses," the bank said.
