Chapter 2.9.3 of the PPP Certification Guide explains the importance and significant benefits of transparency and proactive disclosure in PPP programs. It also provides examples of disclosure policies that are considered to be good practice. In some jurisdictions, it is compulsory to publicly release the contract as-signed.
If the contract is made public, it is good practice to redact any genuinely proprietary or commercially sensitive information where disclosure may disadvantage the winning bidder by making this information available to competitors. Failing to redact such information may deter companies from bidding. In addition, in some projects (such as those in the defence or prison sectors) the government may need to exempt some contractual material from disclosure for public interest reasons.
