since 2010, when there were 826 members. Finances and donors The IPA is funded by its membership, which include both private individuals and businesses. It has a dual structure, with the IPA as a whole reporting revenues of $6.1 million in financial year 2017 which includes funds from its charitable arm, the Institute of Public Affairs Research Trust, which reported revenue of $0.6 million. The IPA has been significantly funded by Hancock Prospecting, of which Gina Rinehart is the Executive Chair. Hancock Prospecting paid the IPA $2.3 million in financial year 2016 and $2.2 million in financial year 2017, which represents one-third to a half of the IPA's total revenue in those years. These payments were not disclosed in IPA annual reports, and Rinehart's daughter Bianca Hope Heyward submitted in court that the Hancock Prospecting payments were credited to Rinehart in an individual capacity. Gina Rinehart was made a life member of the IPA in November 2016. Other businesses who fund or have funded the IPA include ExxonMobil, Telstra, WMC Resources, Philip Morris, Murray Irrigation Limited, Visy, Clough Engineering, Caltex, Shell, Esso and British American Tobacco (BAT). Funders are able to "earmark" their payments to support the work of particular units within the IPA. The Institute of Public Affairs has also been funded by Liberal Party associated entity the Cormack Foundation. In 2003, the Australian Government paid $50,000 to the Institute of Public Affairs to review the accountability of NGOs. Political links The IPA Victoria was founded during World War II by businessmen in response to the feared growing power of the Labor Party and international socialism, with founder C. D. Kemp putting the case to the Victorian Chamber of Manufactures sub-committee as such: The IPA Victoria was founded as an apolitical organisation, and rejected the IPA NSW's strategy of "direct short term political action to defeat the Labor Party with an emphasis on propaganda". However, the IPA Victoria acted as a finance committee for non-Labor parties in its first year, and the IPA Treasurer at the time reportedly said that much of the IPA Victoria's funding was conditional on it being spent to "fight socialism at the coming election" (the 1943 Australian federal election). Its Publicity and Research Bureau wrote political broadcasters, provided speakers' notes to all endorsed United Australia Party and United Country Party candidates and producing advertisements. The IPA Victoria's direct involvement in federal politics was reappraised
