The Office of the New York City Comptroller was created in 1801 to be the chief auditor of local government and all its various financial activities. The comptroller's top responsibilities, as bullet-pointed on the office's website, are "conducting performance and financial audits of all City agencies," "serving as a fiduciary to the City's five public pension funds," "providing comprehensive oversight of the City's budget and fiscal condition," "reviewing City contracts for integrity, accountability and fiscal compliance," and "resolving claims both on behalf of and against the City."
