The group pushing to bring the 2024 Summer Olympics to Boston raised $2.8 million during the first quarter of the year, and spent just over $2 million, according to a report released Friday.

The biggest donors to the group were John and Cyndy Fish, who contributed between $1 and $2 million. John Fish is a construction magnate and the group's former leader.

The law firm Mintz Levin and the data storage company EMC Corporation contributed between $500,000 and $1 million.

The report by the Boston 2024 Partnership also included the salaries of those working for the group.

Six individuals are pulling down annual salaries of more than $100,000 including the group's chief executive officer and former state transportation secretary Richard Davey, who is making a $300,000 annual salary.

The group's chief operating officer and chief bid officer Erin Murphy is being paid a $215,000 annual salary. The group has 20 paid positions.

The report also lists more than two dozen consulting firms and individuals who were paid a total of $1.1 million during the first three months of the year.

"In adopting this expanded set of disclosures, the Boston 2024 Partnership is managing its operations in a transparent way that far exceeds regulatory requirements and standards of other nonprofit organizations," Boston 2024 Chairman Steve Pagliuca said a written statement.

Pagliuca said as a privately-funded nonprofit organization, the Boston 2024 Partnership is required to file disclosures with the federal Internal Revenue Service each year. He said, starting with Friday's report, Boston 2024 will also issue progress reports each quarter.

Pagliuca said the group worked closely with Boston Mayor Marty Walsh, a supporter of the bid, and with state Attorney General Maura Healey to develop the disclosure protocols in the report.

Healey's office issued a statement after the report was released Friday afternoon.

The statement said Healey has urged Boston 2024 "to publicly disclose information about their donations and expenditures, to do so on a more frequent basis, and to have clear policies regarding related-party transactions and conflicts of interest."

"Today's disclosures represent a significant level of transparency beyond what is required of other charities," the statement said.

The bid has met with skepticism and resistance from critics and some neighborhood residents who have pushed for more information about where the sporting venues will be located and whether taxpayers will be on the hook for any costs associated with the games.

Boston, Rome and Hamburg, Germany are declared bidders for the 2024 Summer Games. Paris and Budapest, Hungary, are expected to join that group before the Sept. 15 deadline for submitting bids.

The International Olympic Committee is scheduled to choose the host city in 2017.
