Cohen & Steers (CNS) said Monday its preliminary assets under management reached $93.07 billion as of Jan. 31, up from $90.54 billion at the end of December.

The increase was driven by $2.20 billion in market appreciation and $449 million in net inflows, partially offset by $153 million in distributions, the company said.

Open-end funds accounted for $44.57 billion of total AUM, followed by $36.22 billion in institutional accounts and $12.28 billion in closed-end funds, Cohen & Steers said.
