15.      Concentration of Risk

The Company maintains its cash and cash equivalents in various bank accounts, the balances of which at times may exceed federally insured limits.  The Company has not experienced any losses related to these accounts, and management does not believe that the Company is exposed to significant credit risk.

Management believes that adequate provision has been made for risk of loss on all credit transactions.

The Company buys a significant amount of its disposable protective apparel products from a limited number of subcontractors located in Asia and, to a much lesser extent, a subcontractor in Mexico. Management believes that other suppliers could provide similar products at comparable terms.  A change in suppliers, however, could cause a delay in shipment and a possible loss of sales, which would affect operating results adversely.

The Building Supply segment buys semi-finished housewrap and synthetic roof underlayment from its joint venture, Harmony, located in India.  Although there are a limited number of manufacturers of the particular product, management believes that other suppliers could provide similar products at comparable terms.  A change in suppliers, however, could cause a delay in shipment and a possible loss of sales, which would affect operating results adversely.

The Company provides products to customers located primarily in the U.S.  Customers accounting for 10% or more of accounts receivable as of December 31, 2012 and 2011, and 10% or more of net sales for the years ended December 31, 2012 and 2011, were as follows:
