raw materials and energy we purchase a variety of raw materials and energy from sources in many countries for use in our production processes . we have a policy of maintaining , when available , multiple sources of supply for materials . however , some of our individual plants may have single sources of supply for some of their raw materials , such as carbon monoxide , steam and acetaldehyde . although we have been able to obtain sufficient supplies of raw materials , there can be no assurance that unforeseen developments will not affect our raw material supply . even if we have multiple sources of supply for a raw material , there can be no assurance that these sources can make up for the loss of a major supplier . it is also possible profitability will be adversely affected if we are required to qualify additional sources of supply to our specifications in the event of the loss of a sole supplier . in addition , the price of raw materials varies , often substantially , from year to year. .
