301-51.103—What is my liability if I lose a GTR?
You are liable for any Government expenditure that is caused by your negligence in safeguarding the GTR or tickets received in exchange for the GTR. To avoid liability, immediately report a lost or stolen GTR to your administrative office. If the lost or stolen GTR shows the carrier service desired, and point of origin, promptly notify in writing the named carrier and other local initial carriers. Do not use a GTR that is recovered after having been reported as lost or stolen. Instead, report the recovered GTR to your administrative office.
