To whom it may concern:

I am requesting reimbursement for travel related expenses for my August 22-24th professional conference attendance. I have not requested travel expense reimbursement prior to this trip and I am unfamiliar with the procedures and documents involved in this process. Though I did discuss travel reimbursement procedures with my chair, I was nevertheless under the false impression that the relevant paper work was due in October. As a result I did not submit a travel authorization form prior to the conference travel. My application does contain this form as well as all other supporting documents.

Sincerely,

Dr. Charles Wallis
