A good example of think tank transparency
Grupo FARO from Ecuador has published details about its funding for 2010 on its website. You can also click through to the full auditors report.
The table they have published online, though, is intended to show that Grupo FARO is not dependent on a single funding source and has therefore been published and communicated more proactively than one would usually expect of financial reports (I found out via twitter). The auditors report also describes the projects delivered by Grupo FARO during the same period and it includes information on: the project objective, the funder, the amount provided and spent, and the implementation project period.
There are lots of efforts in the international development community to promote greater transparency of donor policies but not much is asked from the recipients of the funds. This is a good example of a pro-active effort by a think that to be transparent.
