Thanks, Victor. As Victor mentioned, our fourth -- fiscal fourth quarter revenues increased to $22.2 million from $19.6 million a year ago. We generated a gross profit increase of $0.3 million to $5.1 million compared to gross profit of $4.8 million in last year's fiscal fourth quarter. While the gross margin was 23% and was lower compared to the year-ago gross margin of 24.7%. This is primarily attributable to a higher amount of royalties in last year's fourth -- Q4. Additionally, this year, the results include revenue from a sizable customer, while at lower margins, was strategically important for CSPi and allows us to foster closer working relationship, which will yield benefits for many years.
Our first quarter engineering and development expense was significantly lower at $691,000 compared to $925,000 a year ago, which is attributed to a [ reduction in ] contract labor required last year to help in building out the foundation of the ARIA software platform and a recovery of consulting expenses where the services were not completed.
Our SG&A expenses in Q4 were $4.6 million compared to $5 million in last year's fiscal fourth quarter. The decrease in expenses was primarily related to variable compensation and expenses related to the sale of our German subsidiary. The company had a tax expense of $395,000 for the quarter. This was a result of a change in the fourth quarter tax provision which includes the annual adjustment of the deferred taxes, which resulted in an effective tax rate of 16.1%. In the third quarter, we had a tax benefit of $327,000 with an effective tax rate of 158%. The changes in the provision and the rates resulted in the large tax expense in the fourth quarter. We reported a fourth quarter net loss of $334,000 or $0.09 per share compared with net income of $16.2 million or $3.95 per diluted share for the fourth quarter of fiscal 2018. As a reminder, the year-ago net income included a gain of discontinued observations related to the German sale of $16.8 million. However, excluding the gain, we would have reported a net loss of $0.7 million or $0.18 per share, a significant year-over-year improvement. We ended the fiscal year, September 30, with cash and short-term investments of $18.1 million.
Lastly, our Board of Directors has voted to pay a quarterly dividend of $0.15 per share to shareholders of record on December 31, 2019, and payable on January 15, 2020.
Looking to fiscal 2020, we will continue to focus on bottom-line performance and to boost sales of our higher-margin products while managing costs around the company.
With that, I'll turn it over to the operator to take your questions.
