12.            SEGMENT AND SIGNIFICANT CUSTOMER INFORMATION
 
Pursuant to Codification Topic 280, Segment Reporting, we operate in one reportable business segment, that being the development, acquisition, manufacture and sale of products that improve the health and productivity of cows for the dairy and beef industries.  Almost all of our internally funded product development expenses are in support of such products.  Our primary customers for the majority of our product sales (89% and 83% for the three-month periods ended September 30, 2013 and 2012, respectively, and 84% and 81% for the nine-month periods ended September 30, 2013 and 2012, respectively) are in the U.S. dairy and beef industries.  Product sales to international customers, who are also in the dairy and beef industries, aggregated 11% and 17% of our total product sales for the three-month periods ended September 30, 2013 and 2012, respectively, and 14% and 16% of our total product sales for the nine-month periods ended September 30, 2013 and 2012, respectively.
 
The percentage of our total sales that were made to significant customers that amounted to 10% or more of total product sales are detailed in the following table:
