OSP: An activity or cost, which is substantially greater in amount or different in purpose than the normal use.  The term "unlike circumstance" comes from several citations in federal cost principles.  The government requires that costs incurred for the same purposes be consistently charged either as direct costs or as indirect costs.  To allow a charge normally included as indirect as a direct charge, there must be unlike circumstances.  Costs (such as administrative salaries) that are normally charged indirectly must be incurred for reasons and in circumstances that are substantially different from most sponsored awards in order to be charged directly to a grant.
