Significant Concentrations

NOTE L: SIGNIFICANT CONCENTRATIONS

Our ability to satisfy demand for our products may be limited by the availability of those products from our suppliers. We purchase air conditioners from Airxcel, Inc. (“Airxcel”) and generators from Zhejiang Xingyu Industry and Trade Co., Ltd, (“Zhejiang”). Our purchases from Airxcel accounted for approximately 22%, 20%, and 18% of our total product purchases in 2012, 2011, and 2010, respectively. Our purchases from Zhejiang accounted for 6% of our total product purchases in 2012 and 2011, but less than 5% in 2010.

Concentration of Credit Risk. We maintain bank accounts with high quality financial institutions to minimize credit risk. However, our deposit balances may periodically exceed federal deposit insurance limits.
