It is now my pleasure to introduce your host, Mr. Martin Bloch, President and CEO for Frequency Electronics. Thank you, Mr. Bloch, you may begin
Thank you, Martin, and good afternoon, everyone. For the second quarter of fiscal 2015, revenues were $19.2 million, up 13% from last year's $17 million for the second quarter of fiscal '14. Satellite revenues continue to represent approximately 60% of our consolidated revenues, similar to the ratio in the prior year. But in absolute dollars, space revenues were up nearly 20% year-over-year. Revenues from non-space U.S. Government/DOD programs, including sales by FEI-Elcom and FEI-Zyfer, accounted for approximately 20% of consolidated revenues, similar to the ratio of such sales in the year ago quarter.
As we indicated last quarter, FEI-Zyfer had received initial funding on a U.S. Government critical GPS anti-scooping project, and during the second quarter, began to deliver against that program. When we combine U.S. Government/DOD non-space revenue with revenue from U.S. Government satellite programs, this accounts for approximately half of second quarter revenues and a little over 40% of consolidated revenues year-to-date.
The remaining 20% of consolidated revenues is from network infrastructure and other commercial products that are recorded in FEI-New York, Gillam-FEI and FEI-Zyfer, which is compared to approximately 25% of consolidated revenues in the second quarter of last year.
Overall, we anticipate higher revenues from both space and non-space business areas for the balance of fiscal 2015. Gross margin for the second quarter was $6.7 million, compared to $6.2 million last year, resulting in a gross margin rate of 35% in fiscal 2015's second quarter compared to 37% last year.
With higher second quarter sales volume and the company's subsidiaries, FEI-Zyfer and Gillam-FEI, gross margin rates improved from the 29% rate which we recorded in the first quarter of fiscal 2015. Product mix remains an important factor in our gross margin rates.
As consolidated revenues increase, we expect to realize improved gross margin rates over the remainder of fiscal 2015. As we continue to control SG&A expenses at 3.5% or 18% of revenues, this as compared to last year's $3.5 million or 20% of those revenues. This level of SG&A expense is very much in line with our target, and should be sustained throughout fiscal 2015.
Internal research and development spending in the second quarter was $1.4 million or 7% of revenues, compared to last year's $1.5 million or 9% of revenues. Our R&D efforts include investments in products for space, U.S. Government/DOD and other commercial applications, and we expect the rate of IR&D spending to remain at less than 10% of fiscal 2015 revenues. So these results in operating profit of $1.8 million or 9.3% of revenues compared to $1.3 million and 7.4% of revenues in last year's second quarter.
Other income, which generally consists of investment income, offset by interest and other expenses, netted to income of $153,000 in fiscal '15, which is similar to last year before accounting for a gain of $736,000 on the sale of certain manufacturing equipment.
So pretax income was $1.9 million at fiscal 2015 second quarter compared to $.2.2 million in the same period last year. The fiscal 2015 tax provision of $660,000 is at an effective rate of 34% compared to last year's $770,000 or a rate of 36%. The effective tax rate is impacted by the exclusion of operating results of our overseas subsidiaries. For the full fiscal 2015, we expect the effective tax rate to be in the mid-30% range.
So net income for the second quarter of fiscal 2015 is $1.3 million, or $0.15 per diluted share compared to $1.4 million or $0.16 per diluted share in fiscal '14, which also included a one-time gain on equipment sales.
As a result of the [indiscernible] billings and milestone payments, we had negative operating cash flow of $2.5 million for the first 6 months of fiscal 2015. However, in this past second quarter, we generated positive operating cash flow of $3.1 million. With recent billings and milestone payments, we expect to generate positive operating cash flow over the balance of fiscal 2015.
Our backlog at the end of October 2014 was $52 million, which is compared to $48 million at the end of fiscal '14. And again, over 3/4 of our backlog is for long-term satellite programs, split about equally between commercial and U.S. Government programs.
Frequency continues to maintain a healthy balance sheet with a strong working capital position of about $80 million, which is more than sufficient to support substantial growth.
I'll turn it over now to Martin, and we'll probe [ph] your questions later.
