The contribution information should cover any company efforts to "participate or intervene in any campaign on behalf of (or in opposition to) any candidate for public office, or influence the general public, or any segment thereof, with respect to an election or referendum," the document said.
The pension fund seeks the identity of the recipient, the amount paid to each and the name and title of the company executive "responsible for decision-making."
The two shareholder proposals seeking information about contributions to third parties were sent to the Coca-Cola Co. ($394 million) and the Travelers Cos. ($71 million). All investments were as of Sept. 30.
The letter to Coca-Cola, similar to that for Travelers, excluded lobbying from its request. It asked for information on "political activities," which the pension fund defined as "influencing or attempting to influence the selection, nomination, election, or appointment of any individual to a public office."
It also covered "supporting a party, committee, association, fund, or other organization organized and operated primarily for the purpose of directly or indirectly accepting contributions or making expenditures to engage in" political activities.
The pension fund "is in discussions with some of the companies regarding potential agreements," said the news release, which didn't provide details.
