Section 37.705 - What standards do I include for purchasing systems of for-profit firms?(a) If your TIA is an expenditure-based award, it should require for-profit participants that currently perform under DoD assistance instruments subject to the purchasing standards in 32 CFR 34.31 to use the same requirements for TIAs, unless there are programmatic or business reasons to do otherwise (in which case you must document the reasons in the award file).(b) You should allow other for-profit participants under expenditure-based TIAs to use their existing purchasing systems, as long as they flow down the applicable requirements in Federal statutes, Executive orders or Governmentwide regulations (see appendix E to this part for a list of those requirements).(c) If your TIA is a fixed-support award, you need only require for-profit participants to flow down the requirements listed in appendix F to this part.
