In order to assess the developmental effects of OeEB's portfolio, all projects are evaluated with the Corporate Policy Project Rating Tool (GPR©), developed by the German development finance institution (DEG).
GPR© enables both: ex-ante evaluations at the time a project is approved and ex-post evaluations - actual figures during project implementation and after completion. It scores projects based on the following four criteria:
- development impact
- the particular strategic role of OeEB
- the project's long-term profitability
- its contribution to OeEB's expected return on equity.
These four benchmarks are combined in a GPR total index (GPR score), ranging from 'very good' to 'obviously insufficient' (grades from 1 to 6.) Since the developmental effects play a major role, the development impact score (EPOL score) is reported separately, as well as being computed in the average GPR score.
