NTIC's total operating expenses increased 9.9% to $3,727,684 during the first quarter of fiscal 2013 compared to $3,393,068 for the first quarter of fiscal 2012 primarily as a result of an increase in expenses incurred in support of joint ventures and research and development expenses, which NTIC consider critical to pursuing various new business opportunities around the world.Net income attributable to NTIC decreased 59.4% to $389,622, or $0.09 per diluted common share, for the three months ended November 30, 2012 compared to $958,757, or $0.22 per diluted common share, for the three months ended November 30, 2011. This decrease was primarily the result of decreases in gross profits of NTIC's North American businesses as well as decreases in sales and earnings of NTIC's subsidiary in Brazil. NTIC anticipates that its quarterly net income will remain subject to significant volatility primarily due to the financial performance of its joint ventures and sales of its ZERUST® products and services into the oil and gas industry and Natur-Tec® bioplastics products, which sales fluctuate more on a quarterly basis than the traditional ZERUST® business. As of November 30, 2012, NTIC's working capital was $15,306,871, including $6,819,036 in cash and cash equivalents, compared to working capital of $10,060,081, including $4,137,547 in cash and cash equivalents, at August 31, 2012. Outlook For the fiscal year ending August 31, 2013, NTIC has not changed its previous guidance and expects its net sales to range between $27.0 million and $28 million, and expects net income of between $4.4 million to $4.7 million, or between $1.00 and $1.05 per diluted share.
