Inconsistency in ODA-like classification in AidData GCDF v3.0 #32

Open liaochris opened 1 month ago

In GCDF v3.0, there are several loans that are classified as ODA-like even though they are missing key financial information such as interest rates, maturity or grace periods. As a concrete example, AidData record ID#'s 92533, 95856, 90972 from the data contain no interest-rate data (so the grant element of the loan cannot be calculated) but they are classified as ODA-like.

This contradicts the TUFF 3.0 documentation which says that

Projects/activities that are backed by an official commitment but cannot be reliably categorized as ODA-like or OOF-like because of insufficiently detailed information are 25 assigned to the “Vague (Official Finance)” category. Projects/activities in this residual category primarily consist of (a) those with an unspecified “Flow Type” (i.e., values of “Vague TBD”); and (b) those financed with development-intent loans for which AidData lacks the borrowing terms (interest rates, grace periods, or maturity dates) needed for concessionality determinations

How were these loans with missing interest rate information classified as ODA-like?

I've attached a sample extracted from the official data for AidData record ID#'s 92533, 95856, 90972 and more, where interest rate information is unavailable and the loans are classified as ODA-like under the Flow Class variable
