We do not rely on any segment asset allocations and we do not consider them meaningful because of the shared nature of our production facilities; however, we have estimated the segment asset allocations below for those assets for which we can reasonably determine. The unallocated asset category is the remainder of our total assets. The asset allocation is estimated and is not a measure used by our chief operating decision maker about allocating resources to the operating segments or in assessing their performance. The corporate expenses line includes certain unallocated expenses, including primarily salaries, wages and benefits, purchased services, rent, utilities and depreciation and amortization associated with corporate functions such as research and development, information systems, finance, legal, human resources and customer service. Corporate expenses also include the estimated annual incentive plan bonus accrual.
