With every fundraise, PE sponsors face the frustration of having to complete individualized due diligence questionnaires (DDQs) from each potential investor. The Institutional Limited Partners Association (ILPA) recently released an updated version of its DDQ that, like the previous version, attempts to combat that issue by standardizing investor diligence questions. The updated version is longer, is more comprehensive and asks for more detail than the previous one, reflecting more issues of importance to LPs. This article explores the recurring challenge of completing investor DDQ forms; the breadth of adoption of the ILPA DDQ by LPs; and ways the ILPA DDQ can be used by LPs and GPs. It also delves into the sections on credit facilities; diversity, equity and inclusion; and environmental, social and governance, with insightful commentary from attorneys representing both LPs and GPs. For more coverage of ILPA resources, see our two-part series on ILPA’s ESG resources: “Assessment Framework Utility Depends on Stage of LPs’ and GPs’ ESG Programs” (Oct. 12, 2021); and “Iterative Roadmap Can Help LPs in Early Integration Stages” (Oct. 19, 2021).
