Selling, general and administrative ("SG&A") expenses decreased 13% to $2.3 million in the third quarter of fiscal 2013, largely driven by lower stock-based compensation expense and lower vacation pay expense. SG&A expenses decreased to 58% of net sales for the third quarter of fiscal 2013 compared to 62% of net sales reported during the same period last year.
Research and development ("R&D") expenses decreased 52% to $0.3 million in the third quarter of fiscal 2013. The decrease was primarily attributable to lower product development costs associated with the Company's next generation digital processing unit and a reduction in the amount allocated from manufacturing to support R&D efforts. R&D expenses decreased to 9% of net sales compared to 17% of net sales during the same period last year.
The Company's operating loss in the third quarter of fiscal 2013 was $1.5 million, a decrease of $0.5 million, or 25%, compared to the third quarter of fiscal 2012. Lower operating expenses of $0.7 million contributed to the improvement in operating loss during the period.
At December 31, 2012, the Company had cash and cash equivalents of $1.3 million and working capital of $6.6 million, compared to cash and cash equivalents of $2.7 million and working capital of $6.0 million at March 31, 2012. The Company also has $5.0 million of capital available under a $20.0 million convertible note with Lewis C. Pell, the Company's Chairman.

Use of Non-GAAP Financial Measures
Non-GAAP net loss and non-GAAP net loss per share excludes non-cash or non-operational activities. As a result, the Company uses these measures to assess and analyze its operational results and trends and to make financial and operations decisions. The Company also believes these non-GAAP financial measures are useful to investors, because they provide greater transparency regarding the Company's operating performance. These non-GAAP financial measures should not be considered measures of the Company's liquidity. In addition, these non-GAAP financial measures are unlikely to be comparable with non-GAAP information provided by other companies. Reconciliations between non-GAAP financial measures and GAAP financial measures for net loss and net loss per share are included in a table accompanying this press release after the unaudited condensed consolidated financial statements.
