Trends in Project Ratings
by Year of Approval and Source of Funding
(Combined Completion and Evaluation Results)

The figure below shows that the success rates of Asian Development Fund -funded projects approved before the 1990s tended to be considerably lower than those funded by ordinary capital resources, and average ADF ratings were much more volatile. In the 1990s, however, the OCR and ADF ratings converged, and both improved.

While the improving trend suggests that the design and/or implementation of sovereign operations have progressively improved it is important to note that there are several caveats about the trend toward better success rates: (i) rated sovereign operations approved from 1997 to 2000 comprised 59% of total processed sovereign operations during the period; the remaining 41% are still under implementation; (ii) there is a possible bias towards more positive interpretation of success in later years, since the more recent ratings rely heavily on PCRs; and (iii) sovereign operations approved in the 1990s that have experienced long delays in implementation and have not been completed are likely to have a lower than average success rating.

ADF = Asian Development Fund; OCR = ordinary capital resources

Note: Figures for recent years may change as more project completion reports and performance evaluation reports are completed. The figures for approval year 2000 represent only 17% of the total approved projects and programs for that year.
Project/program implementation: 4-7 years
Completion report: 1-2 years after completion
Project/program evaluation: 3 years or more after completion

Project Success by Country

Performance by country varies significantly, though a common trend is evident—that results in most countries were considerably better in the 1990s than in the 1980s. Countries with strong institutional capacity performed well. Other country factors, such as economic performance, development priorities, and quality of governance also contributed to project success.

Project Success by Country Classification

The table below demonstrates improvement from the 1970s to the 1990s across all country groupings, though patterns of progress differ. By the 1990s, the success rate of each group with access to ADF had gradually increased, and countries in Group A (with the exception of Nepal) were performing better than those in Groups B1 and B2.

Since 1977, ADB has had a three-tier classification system that forms the basis for determining the eligibility of DMCs to borrow from ADF and for applicable limits on ADB financing of project costs. DMCs are classified into three groups based on two criteria: (i) per capita gross national product, and (ii) debt repayment capacity. Group-A DMCs are fully eligible for ADF, Group-B DMCs ("blend" economies) are eligible for limited amounts of ADF in particular circumstances, and Group-C DMCs are not eligible for ADF financing.

Project Performance by Sector and Source of Financing

The likelihood of project success by sector is depicted in the table below. Findings indicate that both OCR- and ADF-funded projects generally perform similarly in the same sectors, with certain important exceptions. The ratings of ADF-funded projects eventually converged with those of OCR-funded projects across sectors from 1970 to 1997.
