Raleigh, N.C. — State Treasurer Richard Moore said Friday that choosing outside managers to invest North Carolina's massive retirement funds is based on financial principles and has nothing to do with political contributions he has received.

Moore defended himself after media reports highlighted campaign donations he has received from employees of investment firms that have pension contracts and the day after the State Employee Association of North Carolina took up the issue.

"The people who have been chosen to do business with the state of North Carolina have provided good value to the people of North Carolina," Moore told reporters.

The employee group's executive director, Dana S. Cope, said in a letter dated Thursday that the members were concerned over reports that Moore had refused to turn over some records to Forbes magazine until the magazine threatened a lawsuit.

Moore said he has no plans to return the donations because pension decisions aren't influenced by contributors.

"I'm not endorsing them. I'm not trying to get behind their motives," Moore said after giving reporters an overview of the $74 billion pension fund system, which has been ranked among the strongest in the country. "Everyone we have hired has given great value to (our) mission."

SEANC said it wants all documents related to the dispute with Forbes and an accounting of how Moore paid the law firm that he hired for the matter. The organization also asked for copies of all reports Moore has been required to file with the Legislature, a list of any required reports that weren't filed and performance reports on all pension managers' performances and how much they were paid.

Moore, a likely candidate for the 2008 Democratic nomination for governor, has received campaign donations from employees of nearly half the companies that have contracts to manage the money. Those donations—about $736,000—are equal to about 13 percent of his campaign fundraising since he first started running for treasurer in 1999.

Moore hasn't been accused of any wrongdoing. He contends that he's been open about how the retirement system operates and has listed the donors on his campaign finance reports.

"We don't have any questionable contributions," Moore said. "Both sides of the ledger, I don't think anything questionable has been done."

The state's retirement system invests for an estimated 700,000 state employees, teachers, retirees and others. It is one of a handful of public funds nationwide that are fully funded - meaning there is money available today to pay off all retirees, Moore said.

He said the funds are operated conservatively. Since taking office, Moore has won legislative approval to place a greater percentage of investments in alternative investments such as real estate and hedge funds. These funds require Moore's office to pay higher fees than indexed funds, but they can also bring larger returns.

He said his office undergoes a comprehensive process to determine who will win management contracts.

"I would never sacrifice the long-term integrity of this fund for short-term gain," he said.
