The overall introduction to this Reference Guide provided a broad definition of PPP, as a 'long-term contract between a private party and a government entity, for providing a public asset or service, in which the private party bears significant risk and management responsibility, and remuneration is linked to performance'. This section delves into that definition in more detail: describing (in Section 1.1.1) the range of PPP contract types, and the different nomenclature used to describe those contract types; as well as clarifying (in Section 1.1.2) some related types of 'partnership' between public and private sector parties to which the definition, and more importantly the guidance material, in this Guide would generally not apply.
