Anticorruption and Integrity

Underpinned by ADB's zero tolerance for corruption, the Office of Anticorruption and Integrity aligns with ADB’s commitment to strengthen governance across Asia and the Pacific as it mitigates integrity risks, investigates integrity violations, and promotes integrity among ADB’s stakeholders.

Proactive Integrity Review

A cornerstone of an effective anticorruption program is to actively identify and address risks of fraud and corruption.

As mandated by ADB’s Anticorruption Policy, the Office of Anticorruption and Integrity conducts proactive integrity reviews (PIR, formerly known as project procurement-related reviews) to help prevent and detect integrity violations.

OAI carries out PIRs of ongoing sovereign operations to assess whether ADB financing is being used for its intended purposes. PIRs assess project integrity risks by identifying any red flags of integrity violations through:

  Capacity Assessment

Assessment of the executing/implementing agency’s capacity to implement the project including its internal controls.

  Asset Management

Inspection of project outputs and assessment of project implementation.


Review of projects from bid preparation to evaluation and contract awards.

  Financial Management

Assessment whether disbursements are based on the progress of contract implementation including invoicing, certification of works, and authorizations.

PIRs recommend measures to protect project resources. Follow-up reviews are also conducted to assess the implementation progress of the PIR recommendations, and to assist the executing/implementing agencies and ADB in implementing any remaining recommendations.

These checklists were developed to help project teams of executing and implementing agencies better manage and implement ADB projects. Contact OAI if you are interested in receiving training on how to use the checklists.

Reports of Proactive Integrity Review (PIR)

Proactive Integrity Review (PIR), formerly known as Project Procurement-Related Review (PPRR), reports are intended to help executing agencies, implementing agencies, and ADB to identify and develop preventive measures to mitigate risks of fraud and corruption, improve project management, enhance project implementation, and replicate lessons learned for future projects.

Executing/implementing agencies are expected to develop an action plan to implement PIR recommendations, which will be monitored by the Office of Anticorruption and Integrity through follow-up reviews.
