Just pulled this out of the partial for now because we don't need it as a partial (this view isn't shared). The existing code was extremely gangsterish, e.g. no presentation on the fees (they're rendered as bare ints without formatting). Want to come back to redo this using a presenter to properly decorate all the information rendered to the user.
