If my business travel expenses will be covered by a third party (e.g., host institution), do I still need an approved Spend Authorization before I travel?

A Spend Authorization is required for all business travel that is 45 miles or more from the traveler's headquarters to document for duty of care purposes.  When the business travel is financially supported by a third party, the Spend Authorization must include each expense line for anticipated expenses with appropriate expense item type (e.g., airfare) and entered with the amount of $0.01, along with comments in the memo field indicating expenses paid by third party name.
