The language from the indirect cost rate agreements for the
 University of California campuses (DHHS Region IX) reads:

 Definition of Off-Campus rate:
 The off-campus rate is applicable to those projects
 conducted at facilities not owned by the University.

 Projects conducted entirely on-campus or entirely
 off-campus:
 Projects conducted entirely on-campus or entirely off-campus
 will be applied the on-campus or off-campus rate
 respectively.

 Projects conducted partially off-campus and particlly
 on-campus:
 If the project involves work at both on-campus and
 off-campus sites, either (underlined) the on-campus or
 off-campus rate generally should be applied, consistent with
 where the majority of the work is to be performed.  Salary
 cost is generally accepted as a measure of work performed in
 terms of the total project.

 Use of Both On-campus and Off-campus Rates:
 The use of both on- and off-campus rates for a given project
 may be justified if both of the respective rates can clearly
 be identified with a significant portion of salaries and
 wages of the project.  For purposes of this provision,
 significant is defined as approximately 25% or more of the
 total costs and a project's total salary and wage costs
 exceed $250,000.
