Development finance
Other Official Flows (OOF)
Official development-related financial flows that do not meet the concessionality criteria for Official Development Assistance.
Definition
Other Official Flows are transactions by the official sector to developing countries and multilateral institutions that do not qualify as Official Development Assistance — either because their primary purpose is not development (for example export-related official finance) or because they are not sufficiently concessional under OECD DAC criteria.

Overview
What it means
OOF captures the substantial volume of non-concessional official lending and investment to developing countries. Tracking it alongside ODA gives a fuller picture of total official support for development, a measure now formalised as Total Official Support for Sustainable Development (TOSSD).
How it is used
The OECD DAC reports OOF in its creditor reporting statistics; analysts use the category to compare concessional and non-concessional development finance across donors and instruments.
Why it matters
Distinguishing OOF from ODA preserves the integrity of aid statistics and clarifies what counts as development assistance, a matter of accountability for donors and of realism about the finance actually available to developing countries.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
