The firm has closed its fifth and largest dedicated aviation fund.
The commitment represents a new relationship for the city’s three pension plans.
The deferred compensation plan is also slated to receive results in its active domestic core fixed-income manager search in May.
The firm’s employee ownership has grown to more than 70 shareholders.
The pension plan will also consider candidates in its executive director search next month.
The search follows the Jan. 3 departure of Chief Financial Operating Officer Ryan Skor.
The retirement system made a $25 million private equity commitment last month.
The retirement system also canceled its general investment consultant RFP and approved a 2025 private markets pacing plan in January.
Bolton Investment currently provides investment consulting services for the plans.
The fund was oversubscribed and raised in less than six months.
