TriNet and WR Hambrecht + Co Evaluated as an HR Outsourcing Partnership by Leading Analyst Firm

SAN LEANDRO, Calif. (December 18, 2006) - TriNet, a nationwide provider of human resource (HR) outsourcing services for small and mid-sized companies, was recently analyzed in a case study developed by leading analyst firm Gartner, Inc. The case study, entitled WR Hambrecht + Co's Contract with TriNet is a Midsize-Business HR Outsourcing Success Story, Robert H. Brown, September 29, 2006, highlights the eight-year relationship between TriNet and its customer, WR Hambrecht + Co, an investment bank located in San Francisco, CA.

"I was pleased to talk about the long-term relationship we have built with TriNet for this case study and discuss the benefits of WR Hambrecht + Co's long-term relationship with TriNet," said Veronica Bryan, WR Hambrecht + Co's Director of Human Resources. "Using TriNet as our sole provider of payroll, benefits, and HR services has been a decision that we've constantly revisited to ensure that it makes business sense. But TriNet has proven its ability to positively affect the growth and success of the company, even when its competitors have come to the table with other offers. TriNet is the right cultural fit for a high-performance financial services company such as ours. Its technology and customer service are outstanding, and we've appreciated having the company be our 'virtual HR department' since 1998."

"We're gratified that there remains a continual focus on successful HR outsourcing partnerships within the small and mid-sized market," said Martin Babinec, TriNet's President & CEO. "We've appreciated working with WR Hambrecht + Co over the years and we believe that the case study will be of value to other companies seeking to improve growth and revenue through a carefully chosen HR business processing outsourcing (BPO) arrangement."

According to the Gartner case study, middle market purchasers of HR outsourcing evaluate a number of factors when deciding on a HR BPO partner. The study observes that "In most cases, they want to know where the vendor has delivered HR BPO to similar-size businesses (especially in the same vertical industry) and developed a track record of good customer service over a number of years and attained hard-dollar results."
