Industry fund-affiliated private equity firm the Anacacia Capital has added two new assets to its Anacacia Partnership portfolio.

The firm took majority stakes in safety product provider Roof Safe Enterprises and hydraulic services provider Planet Services Group.

The firm could not disclose any financial details, but said it typically sought to invest in companies with between $20-50 million in annual revenues.

Planet Services managing director Anthony Alafaci welcomed the investment.

"Their due diligence process was very rigorous and a great learning opportunity for our business, and much of what we learnt we will put into practice," he said.

"We feel very fortunate to have attracted Anacacia who will add a depth of talent to our business going forward," he said.

Roofsafe was looking for an investment partner to help provide both strategic and financial strength to continue its expansion.

Financial services firm HLB Mann Judd was one of the advisers on the transactions.

The addition of the two companies brings the total portfolio to six comapanies, including Appen ButlerHill, Home Appliances, Norwest Productions and Rafferty's Garden.

Anacacia sold in December last year Lomb Scientific in a trade sale.

The fund is closed to new investors although InvestorDaily understands that Anacacia may be about to open a new fund next year following a similar strategy of focusing on private equity into small-medium enterprises.

Anacacia was recently named the world's best-performing private equity fund based on data by research firm Preqin, which ranked firms on funds raised during the period 2006 - 2008.

"It is terrific to receive this accolade," Anacacia founder and managing director Jeremy Samuel said.

"This is a great reflection of the quality of our Anacacia SME executives. It demonstrates that, even during tough times, Australia can generate the very best returns globally from private equity backed small-medium enterprises," he said.

Anacacia is backed by several investors including the Niche Emerging Private Equity Manager Fund (NEPEM).

NEPEM was established by The Private Capital Group, a group of investors that included 10 industry superannuation funds.
