The PSigma deal brought in £749m, while other net inflows of £351m flowed into the Miton funds and investment trusts.
Reflecting the boost, the company increased the price of its dividend 20% to 54p.
Net revenue stood at £15m, up 29.3% from the previous year, but profits before tax were down 22.2% to £700,000, from £900,000 last year.
"Over the last three years the Group has decisively scaled up for growth with some of the most highly regarded people in the industry joining the group,” executive chairman Ian Dighé said.
“2013 saw a step up in interest in our 'Beyond the credit boom' investment strategies which delivered significant organic growth. As at 28 February 2014, total AuM stood at £3.2bn.”
The sale of its Liverpool fund management business is set to be completed on 31 March. Despite an expected £450m drop in AUM, the deal is expected to boost free cash balances and reduce regulatory capital requirement.
