The firm raised the capital for its second fund in 18 months from 185 investors.
The fund's target is almost three times that of its predecessor, the 2013-vintage Lexington Middle Market Investors III, which closed on about $1bn.
The fund, run by HQ Capital, is expected to hold a first close in the autumn on around a quarter of its $400m target, according to sources.
The banking group's Five Arrows Secondary Opportunities unit has also hired three staff this year including a secondaries executive from BEX Capital.
The firm has collected about half the €400m target for SwanCap Opportunities Fund III which can invest in direct secondaries.
The pension has committed $100m to a vehicle that will invest alongside the Carlyle unit's latest real estate-focused secondaries fund.
Secondaries investments made up 23% of investment volume, and a further 22% went into “select private markets managers”, the firm said.
The C$287bn pension fund is losing global head of private investments Mark Jenkins, who is leaving to join Carlyle.
The firm has raised €164m for Stafford Infrastructure Secondary Fund II, more than two-thirds of its target.
The firm has raised €350m and is hoping to raise a total of €400m by the end of the year.
