During the three months ended November 30, 2012, 90.6% of NTIC's consolidated net sales were derived from sales of ZERUST® products and services, which increased 7.7% to $4,795,283 compared to $4,452,646 during the same prior fiscal year period, due primarily from increased demand from existing customers and the addition of new customers. NTIC has focused its sales efforts of ZERUST® products and services by strategically targeting customers with specific corrosion issues in new market areas, including the oil and gas industry and other industrial sectors that offer sizable growth opportunities. NTIC's consolidated net sales during the three months ended November 30, 2012 included $551,814 of sales made by Zerust Brazil, and of those sales, $40,385 in sales were made to the oil and gas industry sector in Brazil.During the three months ended November 30, 2012, 9.4% of NTIC's consolidated net sales, respectively, were derived from sales of Natur-Tec® products, which increased 30.8% to $496,464 compared to the three months ended November 30, 2011. This increase was due to increased sales to Natur-Tec® distributors on the West Coast of the United States as NTIC continued to strengthen and expand its U.S. industrial distribution. Lynch added that, "As we introduce new technologies, we also continue to add oil and gas industry companies to our list of customers in several countries, including the United States. However, we expect sales to these new clients to build slowly, as technical evaluations and implementation roll-out plans are finalized." NTIC's equity in income of joint ventures decreased 15.0% to $1,154,296 during the three months ended November 30, 2012 compared $1,357,680 during the three months ended November 30, 2011 primarily as a result of the consolidation of NTI Asean. NTIC recognized increased fee income for services provided to joint ventures primarily as a result of consolidation of the fees for services earned by NTI Asean, partially offset by a 4.4% decrease in total net sales of NTIC's joint ventures to $27,524,934 during the three months ended November 30, 2012 compared to $28,795,232 for the three months ended November 30, 2011. Total net sales of NTIC's joint ventures were adversely affected in part by the European economic slowdown, which NTIC believes also adversely affected net sales of certain of NTIC's other non-European joint ventures. Sales of NTIC's joint ventures are not included in NTIC's product sales and are not combined with NTIC's sales in NTIC's consolidated financial statements or in any description of NTIC's sales.
