Materials are the most significant component of cost of sales. Bulk paper is our main materials cost.
Personal hygiene products and examination table paper have a high materials component and a low
labour component. By comparison, gowns, drapes, mitts, sheets and pillowcases have a higher labour
component and a relatively lower materials component. Our margins are lower for the personal hygiene
products, where much of the recent has growth occurred, than for the other product lines.
Paper prices, our most significant materials cost, have increased every year since 2006. Exchange rate
fluctuations; however, generally worked in our favour to offset the higher US dollar prices until the current
year. During the latter part of our 2009 fiscal year, the exchange rate fluctuations started to increase our
costs even more. We expect that paper prices will continue to remain unsettled during our 2010 fiscal
year. Our prices to our customers have been set to allow for paper cost increases of up to 10%.
Materials costs also fluctuate from differences in the yield factors (the amount of product that a certain
weight of paper will produce).
We had some difficulty obtaining paper supplies during the years ended March 31, 2008, 2007 and 2005
because of a shortage in supply and estimate we lost $200,000 of sales in 2005 and between $100,000
and $150,000 during 2007 and 2008 as a result. We have expanded our range of paper suppliers and
have increased our raw paper inventories in an attempt to ensure an uninterrupted supply in the future;
however, the inability to obtain paper at our current input prices may result in lost product sales or in
higher materials costs.
Labour in cost of sales averaged 8.2% of sales during 2009 and has been relatively stable over the last
five years. The current labour market near our factory was tight during the year and it is took extra time to
find and train new machine operators. We have seen some relief in the last few months caused by a
slowdown in the local construction industry. If we are unable to hire sufficient machine operators, we will
not be able to produce the additional products for sale.
Variable overhead normally fluctuates slightly from one period to the next. Increased maintenance
activities, factory supervision, training and stock transfer costs account for the earlier increases in variable
overhead. We curtailed some of these activities during 2008 and 2009 and reduced the costs to a more
sustainable level.
Higher rent added $56,629 to fixed overhead in 2008 and $28,861 in 2007. We rented additional
warehouse space which increased fixed overhead. Other fluctuations in fixed overhead are due to
differences in insurance premiums. Increases in depreciation expense are the result of bringing new
equipment into use.
