Good afternoon, Rebecca:
Completely agree with Mr. Taylor here. Gift Acceptance policies, IMHO, are intended to address both the immediate and ongoing (far beyond any campaign) parameters for both what is acceptable for the organization to receive and also address any subsequent disposal - if necessary - of contributions. These core policies should be positioned to address acceptance practices beyond targeted campaign structure.
Hopefully you'll get some other input here, but I also go back to simple Google searches to find tremendous examples of practices - gift acceptance policies and otherwise - as most organizations have become transparent about how they have defined such structures.
With best regards,
Amy
