It is now my pleasure to introduce your host, General Joe Franklin, Chairman of the Board for Frequency Electronics.
Thank you, General Franklin, you may begin
All right. Thank you, Joe, and good afternoon, everyone. For the second quarter of fiscal 2014, Frequency had revenues of $17 million compared to $16.8 million in the first quarter of this fiscal year and compared to $17.6 million in the year-ago quarter. Revenues from satellite payloads remained a dominant market for Frequency and the area of largest expected growth going forward. Satellite payload revenues increased nearly 20% over the prior year and accounted for over 55% of consolidated second quarter revenues, similar ratios as in the first quarter. Revenues from non-space U.S. Government/DOD programs, including sales by FEI-Elcom and FEI-Zyfer accounted for about 20% of consolidated revenues compared to the high 20% range last year. Total revenues for U.S. Government/DOD end-use both for space and non-space programs account for approximately 60% of Frequency's consolidated revenues.
Network infrastructure revenues, which are recorded in FEI-NY, FEI-Zyfer and Gillam-FEI were about 15% of consolidated revenues, down slightly from the prior year. Based on current backlogs, plus our new satellite bookings for legacy products, which were awarded in the first half of this year, we anticipate continued strong revenues from the satellite payload market in fiscal year 2014.
Cost of sales in the second quarter of both years was approximately $10.8 million, resulting in gross margin of $6.2 million in the fiscal 2014 quarter compared to $6.7 million last year. The gross margin rate was 36.6% in fiscal 2014 compared to 38.3% last year. As we have discussed previously, our gross margin rate is impacted by product mix and a lower sales volume at our subsidiaries.
Fiscal 2014 SG&A expenses of $3.5 million were comparable to last year's $3.5 million, and were at 21% of revenues in this current fiscal year compared to 20% of revenues last year. This level of SG&A expenses is in line with our expectations and as revenues increase, we would expect to see the ratio of SG&A expenses to revenues to decrease.
R&D spending in the second quarter was $1.5 million compared to last year's $1.2 million. As noted in our first quarter conference call, we continued to accelerate R&D spending on our newly expanded satellite payload product line of microwave receivers and up/down converters. Year-over-year, IR&D spending is up $600,000, which reduced fiscal 2014 profit margin by about 2%. We expect the rate of R&D spending to moderate during the second half of fiscal 2014. Thus, fiscal year second quarter operating profit is $1.3 million compared to $2 million last year.
Other income, which generally consists of investment income, offset by interest and other expenses, netted to income of $897,000 in the second quarter of this year compared to income of $92,000 a year ago. During the second quarter, we recognized a gain of $736,000 on the sale of certain manufacturing equipment under a rubidium oscillator license agreement. This yields pretax income of $2.2 million compared to $2.1 million last year, and net income was about $1.4 million each year. Diluted earnings per share were $0.16 in fiscal 2014 versus $0.17 in fiscal 2013 due to a higher tax provision in the current year. In fiscal 2014, the tax provision was recorded at an effective rate of 36% compared to last year's rate of 32%. Now this depends on the profitability of our foreign subsidiaries, which we anticipate our effective rate to fall in the range of 32% to 36% for all of fiscal 2014.
For the 6 months of fiscal 2014, we used $2.5 million of operating cash flow, primarily due to growth in accounts receivable and inventory. The growth in inventory is in preparation for the production phase of the multi-satellite Iridium program and other recently booked new contracts. As we consume this inventory, we expect to generate increased revenues and positive operating cash flow in the second half of this current fiscal year.
Our reported backlog at the end of October was $57 million compared to $51 million at the beginning of this fiscal year. Except with respect to cost plus contracts, our backlog includes only the funded portion of long-term contracts. Following the end of the second quarter, we expect to receive additional funding of approximately $20 million on booked orders, which will be recorded in backlog at the time of funding as this year progresses. Over 3/4 of our backlog is for long-term satellite programs, split about equally between commercial and U.S. Government programs. However, based on recent satellite bookings, we expect the ratio of commercial satellite programs in our backlog to increase.
Frequency continues to maintain a healthy balance sheet, with a strong working capital position of $77 million.
I'll turn the program over to Martin and look forward to your questions later. Martin?
