Thank you, Alex.
As Alex noted, net sales for the third quarter of fiscal 2018 were $3.6 million or $1.7 million lower when compared to the same quarter a year ago. Net sales in our defense market increased by $1.6 million -- I'm sorry, decreased by $1.6 million when compared to the same quarter a year ago primarily due to lower shipment volume and a slowdown of project activity caused by customer funding delays. Net sales in our precision industrial market increased by $0.3 million, while net sales in our nuclear market increased by $0.2 million when compared to the same quarter a year ago.
Gross profit was $0.4 million, a decrease of $1.6 million when compared to the same quarter of fiscal 2017. The decrease can be attributed to lower sales volume, higher shipments of low-margin products and unabsorbed overhead costs in connection with the slowdown in project activity.
Our net loss for the quarter was approximately $691,000 or $0.02 per share basic and fully diluted for the quarter ended December 31, 2017, as compared to a net income of $992,000 or $0.03 per share basic and fully diluted for the quarter ended December 31, 2016. The third quarter of fiscal 2018 includes a $485,000 noncash discrete tax expense, a result of a revaluation of the company's estimated net deferred tax assets to reflect the new 21% U.S. federal statutory tax rate as provided under the Tax Cuts and Jobs Act, recently enacted on December 22, 2017.
For the 9 months ended December 31, 2017, our net sales increased by 3% to $14.1 million. Gross profit was $3.6 million or a 29% decrease from the same period a year ago. Our gross profit and margin suffered due to the third quarter slowdown and higher shipments of low-margin products mentioned earlier. Income from operations was $1.4 million, a 48% decrease when compared to the same period a year ago.
For the 9 months ended December 31, 2017, we recorded tax expense of $946,000. This tax expense includes the $485,000 noncash discrete tax expense that was booked in the third quarter. Our tax expense is primarily a noncash expense, as we continue to utilize our deferred tax assets to offset any tax liability. Cash paid for income taxes was $30,000 for the 9 months ended December 31, 2017. The company does not expect to make any other significant tax payments for the remainder of the fiscal year.
Our net income for the 9 months ended December 31, 2017, was approximately $101,000 or $0.00 per share basic and fully diluted, for the quarter (sic) [ 9 months ] ended December 31, 2017, as compared to a net income of $2 million or $0.07 per share basic and fully diluted for the quarter (sic) [ 9 months ] ended December 31, 2016.
Year-to-date fiscal 2018 earnings per share is based on an average weighted share count of approximately 28.8 million and 29.6 million for basic and fully diluted shares, respectively.
Turning to the balance sheet. We finished the quarter with $3 million in cash at December 31, 2017. Our working capital increased by $393,000 to $5.4 million at December 31, 2017, compared to $5 million at March 31, 2017. Cash flow provided by operations was approximately $1.3 million in the first 9 months of fiscal 2018. In addition, we used approximately $900,000 of cash to purchase new machinery and equipment that was placed in service during the first 9 months of fiscal 2018.
With that, I will now turn the call back over to Alex. Alex?
