You have been given power of attorney for a close friend's estate. In their will, they have expressed their wish that any money leftover from their estate be donated to a worthy charitable organization. It's up to you to decide which organization to donate to.

Using the links to annual reports below, (1) make a decision and (2) write a short letter reporting your decision with enough evidence from the annual reports to convince any skeptical family that you can be trusted to have made a good decision.
