There are no authoritative criteria for determining a ‘preferable’ classification of shipping and handling costs based on the particular circumstances; however, we conclude that such change in the classification of shipping and handling costs is to an acceptable alternative method which, based on your business judgment to make this change and for the stated reasons, is preferable in your circumstances.

Very truly yours,
