I would like to know how many of you value your materials inventory at the end of your taxation year. Obviously a full sheet of matboard that you purchased during the year for $10 that is still in inventory after all jobs are done, comes straight out of the expenses at year-end and becomes an asset. My question is, what about the 1/2 or 1/3 sheet? And moulding, a good condition 8 ft moulding you paid $80 for is $80 out of expenses, but what if only 4 ft is left - is it $40? - what about 2 ft????
