Thank you, Alex. Net sales were $3.7 million for the third quarter ended December 31, 2019, compared to $4.3 million in the third quarter ended December 31, 2018. Cost of sales for the third quarter was $3.4 million or $54,000 higher compared to the same quarterly period a year ago. The increase was due, in large part, to a $317,000 charge during the quarter for potential losses on certain customer projects, primarily the new projects referred to by Alex.
Selling, general and administrative expenses increased by $31,000 in the third quarter, mainly due to increases in professional fees. Interest expense decreased by $16,000 in the third quarter as we continue to amortize debt principal to maturity.
Net loss for the third quarter was $320,000.
For the 9 months ended December 31, 2019, net sales decreased by 8% to $11.1 million from $12 million when compared to the 9 months ended December 31, 2018.
Our cost of sales for the 9 months ended December 31, 2019 were $9.2 million compared to $8.9 million in the same period a year ago.
Gross profit was 16.6% or $1.3 million lower due to primarily $850,000 of charges for potential losses on certain customer projects.
Total SG&A expenses for the 9 months ended December 31, 2019 increased by approximately $32,000, due primarily to increase in professional fees which were most -- offset by a decrease in compensation expense.
Interest expense decreased by $43,000, again, as we continue to amortize our debt principal.
For the 9 months ended December 31, 2019, our net loss was $390,000 compared with net income of $563,000 for the 9 months ended December 31, 2018.
Moving to the balance sheet, we had $2 million in cash and $5.4 million in working capital at December 31, 2019. Cash provided by operating activities was $0.6 million for the 9 months ended December 31, 2019. Net debt at the end of the third quarter of fiscal 2020 was $1.7 million.
As Alex mentioned, in December 2019, we signed an agreement to increase the amount of available -- amount available under our revolver loan from $1 million to $3 million and decreased our interest rate on the revolver by 50 basis points. In January 2020, we paid off, in full, our remaining debt obligation of $1.1 million on the higher interest rate capital loan equipment. This payment reduced our total debt obligations to $2.6 million at January 17, 2020, from $3.7 million at December 31, 2019.
With that, I will now turn the call back over to Alex. Alex?
