The institutional investor has committed $25m to the vehicle as part of a $274m spread of investments according to P&I.
In January the Pennsylvania Public School Employees’ Retirement System agreed to invest up to $100m in the vehicle, which is believed to have held a $750m first close shortly after.
A person familiar with the matter told AltAssets the firm expected to wrap up the fundraise by the end of the second quarter of 2013.
The firm also targeted $1.5bn for its last Asia buyout fund in 2007.
Fellow buyout giant Carlyle reportedly broke the $1bn mark for its latest Asia-focused private equity fund earlier this week, four months after holding a $700m first close.
Carlyle hit the fundraising trail for the $3.5bn-targeting fund in May last year, shortly after the firm debuted on the Nasdaq stock exchange.
