July 14 (Reuters) - Australia's Steadfast SDF.AX said on Tuesday that the global investment firm KKR KKR.N has joined the consortium of Amwins Group and Dragoneer Investment in their A$7.7 billion ($5.33 billion) proposal to buy out the insurance broker.

Here are some more details:

• KKR joined the consortium as a co-lead investment partner with U.S.-based Dragoneer Investment, which will take control of Steadfast's retail brokerage business if the deal closes.

• As per the previously disclosed deal terms, insurance distributor Amwins will acquire Steadfast's underwriting agency operations.

• Steadfast said Amwins and Dragoneer have confirmed that KKR’s participation will not affect the timetable of the deal the parties are currently aligning to.

• Last week, Steadfast extended the exclusivity period to the consortium by four weeks.

• The consortium has maintained the offer of A$6 per Steadfast share, first tabled in June.
