The conference registration fee is allowable only if the reason for the cancellation meets the criteria for “reasonable” as part of the four cost principles. Criteria to use for “reasonable” would include that the PI could not travel due to circumstances beyond their control (e.g., sudden illness, death of a family member) and that every attempt was made to obtain a full or partial refund from the conference organizers.

Guidance from NIH can be found on NIH's website under the section "Guidance on Salary Limitation for Grants and Cooperative Agreements" for the current fiscal year. NIH's salary cap summary dating back to FY1990 is another helpful resource.

Auditors scrutinize meal purchases because they can include unallowable costs such as alcohol and/or per meal costs over the per diem allocation. Provision of an itemized receipt will provide proof of the cost allowability.

For a single Award, where the controlled substance(s) are required to achieve the objectives of the Award, charging the annual license fee to the Award as a direct cost would be allowable. If the controlled substance(s) are required to achieve the objectives for multiple Awards or other activities, allocating the annual fee to each of the Awards or other activities on some reasonable basis as a direct cost would be allowable. In cases where it is not possible to determine proportional benefits, the annual license fee should be treated as an F&A cost.

This type of expense is not allowable. According to CFR 200.434 Contributions and donations: Costs of contributions and donations, including cash, property, and services, from the non-Federal entity to other entities, are unallowable.

Federal agencies have different requirements. Some agencies may require the same level of effort as was proposed during the original term of the award, but others will not. For instance, NIH currently only requires a “measurable” level of effort for the PI and other key personnel during the term of the award, including any NCE periods. NSF takes a different view and assumes that the originally proposed effort will be spread over the entire award period, including any NCE periods.
