1. The credit given will vary by the agency acting as your primary federal regulator and may also vary by examiner. Our examiners currently would only give us credit for two services (per your example) and only if there were at least 5 clients in attendance per presenter.
2. In this example, your employees did not perform any service. I also would question what did the non profit do at these presentations? You should be able to get some recognition since the curriculum is in the bank's name. Did the bank pay for the creation of the curriculum? Might get you some investment credit.
Just my two cents.....
Societies that do not find work in and of itself "pleasing to God and requisite to Man," tend to be highly corrupt.
