The host committee that produced the festivities surrounding July's Democratic National Convention in Philadelphia exceeded its fundraising goal, collecting $75 million in cash and in-kind contributions, officials announced Tuesday.

The Philadelphia 2016 Host Committee, which was charged with raising at least $60 million, received its largest backing from the state of Pennsylvania, which gave it $10 million, according to a financial disclosure filed Tuesday with the Federal Election Commission. Labor unions donated more than $8 million to help put on the event, with the largest share coming from the International Brotherhood of Electrical Workers, which gave $2.175 million.

A wide array of corporations also poured money into the event. Philadelphia-based Comcast was the largest donor, giving $5.6 million, mostly through in-kind contributions of staff, advertising and hardware. David L. Cohen, a top Comcast executive, served as a senior adviser to the committee. Cohen has been a top fundraiser for President Obama and has helped raise money for Democratic presidential nominee Hillary Clinton.

Other major corporate donors included PECO Energy Co. ($1.8 million), Independence Blue Cross ($1.5 million), Facebook ($1.45 million) and Bank of America ($1 million).

Only two individuals broke the million-dollar mark: J.B. Pritzker, a Chicago-based investor and philanthropist, who donated $1.25 million; and H.F. Lenfest, the former owner of the Philadelphia Inquirer and Daily News, who gave $1 million.

Money also flowed from the pro-Clinton Priorities USA Action, which helped out with $1.5 million.

Some of the donors were not immediately identified. About $4.5 million came to the host committee through the Philadelphia Convention & Visitors Bureau, a workaround that officials created after the host committee failed to obtain its designation as a charity under section 501(c)(3) of the tax code. A spokeswoman for the bureau said that three contributors were willing to have their names disclosed: the Greater Philadelphia Chamber of Commerce ($10,000), the Drumcliff Foundation ($50,000) and the Dyson Foundation ($125,000).

For its part, the host committee for the Republican National Convention in Cleveland raised more than $65 million in cash and in-kind donations, with major sponsors including AT&T (nearly $4.3 million), Microsoft ($1.8 million in software), Jones Day ($1.5 million) and oil interests such as Marathon Petroleum ($1.2 million).
