It is now my pleasure to introduce your host, Martin Bloch, President and CEO of Frequency Electronics. Thank you, Mr. Bloch. You may begin
Thank you, Martin, and good afternoon, everyone. For the first quarter of fiscal 2014, Frequency's revenues were $16.8 million compared to last year's first quarter fiscal 2013 number of $16.7 million. Revenues from satellite payloads remain the dominant market for Frequency and the area of largest growth going forward. Satellite payload revenues increased approximately 16% over the prior year period and accounted for over 55% of consolidated first quarter revenues. Revenues from non-space U.S. government DOD programs, including sales by FEI-Elcom and the FEI-Zyfer accounted for about 1/4 of consolidated revenues. Total revenues for the U.S. Government/DOD end use activities, both for space and non-space programs, continued to account for more than 60% of Frequency's consolidated revenues. Network infrastructure revenues, which are recorded in FEI-New York, FEI-Zyfer and Gillam-FEI, were about 15% of consolidated revenues. Based on our current backlog and new satellite bookings awarded at the end of the first quarter, we anticipate continued strong revenues from the satellite payload market in fiscal 2014.
Our gross margin for the first quarter was $6.3 million compared to $6 million in the year-ago quarter. Now this increased gross margin is due to the increased revenues and improved gross margin rate from 35.8% to 37.2%. As we've discussed previously, our gross margin rate is impacted by product mix and the sales volume of our subsidiaries. Fiscal year 2014 SG&A expenses of $3.6 million were comparable to last year's $3.5 million and were at 21% of revenues in both years. This level of SG&A expenses is in line with our expectations and as revenues increase, we will do expect to see the ratio of SG&A expenses to revenues to decrease.
As we noted in our press release during the first quarter of fiscal 2014, we continued to accelerate our R&D investment in the new satellite payload product line of Ku and Ka band receivers and converters. R&D spending in the first quarter was $1.7 million or 10% of revenues compared to last year's $1.4 million or 8% of revenues. We expect the rate of R&D spending to moderate during the latter half of fiscal 2014 and expect full year R&D spending to be less than 10% of revenues. The higher R&D spending in fiscal 2014 is reflected in the small decline in operating profit from $1,081,000 last year to $963,000 this year.
Other income, which consists of investment income offset by interest and other expenses, netted to income of $93,000 compared to income of $117,000 a year ago. This yields pretax income of $1,056,000 compared to $1,198,000 last year. We recorded the fiscal 2014 tax provision of $380,000 or an effective rate of 36% compared to last year's $430,000, also just about 36%. Depending on the profitability of our foreign subsidiaries, we anticipate that our effective tax rate will fall in the range of 32% to 36% for all of fiscal 2014. This yields net income of $676,000 or $0.08 per diluted share compared to $768,000 last year or $0.09 per diluted share.
Fourth quarter, we used the $2.2 million of operating cash flow, primarily due to the growth in accounts receivable and inventory. With respect to billed receivables, the balance at the end of the first quarter was $12.6 million, up $4.8 million from the $7.8 million balance at April 30. This growth results from our meeting contractual and production milestones during the first quarter, which will generate substantial positive cash flow in the second quarter of this year. Our reported backlog at the end of April -- I'm sorry, at the end of July was about $56 million compared to $51 million at the end of fiscal 2013. Except with respect to cost-plus contracts, we include in backlog only the funded portion of our long-term contracts. Over 3/4 of our backlog is for long-term satellite programs split about equally between commercial and U.S. government programs.
As we announced in June, we established a $25 million credit facility with JPMorgan Chase. During the first quarter, we took down an additional $3 million, of which $1.5 million was used to acquire capital equipment in connection with expected future production requirements. For all of fiscal of 2014, we expect CapEx to be between $2.5 million to $3 million.
I'll now turn the call back to Martin, and we'll respond to your questions a little later. Martin?
