It is now my pleasure to introduce your host, Mr. Martin Bloch, President and CEO for Frequency Electronics. Thank you, Mr. Bloch, you may now begin
Thank you, Martin, and good afternoon everyone. For fiscal year 2013, Frequency Electronics generated $68.9 million in revenues as compared to last year's $63.6 million. Revenues from satellite payloads increased by approximately 11% over the prior year and accounted for half of consolidated revenues. Revenues from non-space U.S. government DoD programs, including sales by FEI-Elcom and FEI-Zyfer, accounted for about 1/4 of consolidated revenues. Year to date, total revenues for U.S. government DoD end use, both for space and non-space programs, account for approximately 60% of our Frequency's consolidated revenues. Network infrastructure revenues, recorded in FEI New York, FEI-Zyfer and Gillam-FEI, were about 17% of consolidated revenues compared to 20% in fiscal 2012. As noted in the press release, during the fourth quarter, FEI-Zyfer experienced delays in orders and lower-than-anticipated revenues for both U.S. government and commercial customers. We believe the U.S. government business for FEI-Zyfer was impacted by the current budget situation in Washington. Based on our current backlog and additional back satellite bookings expected in the near term, we are anticipating continued revenue growth in fiscal year 2014.
Gross margin for fiscal 2013 was $25.1 million compared to last year's $24.6 million. Higher revenues resulted in increased gross margin dollars, but the gross margin rate was impacted both by product mix in our non-New York subsidiaries and by a $1.4 million fourth quarter charge to write-off certain assets on Gillam-FEI. to explain this onetime charge a little more, a few years ago, Gillam-FEI became engaged with a French electrical power utility, to provide upgraded versions of one of its products, remote terminal units or RTUs. These RTUs -- to monitor the power grid. This effort is tied in with the French government's plan to install smart meters throughout France and to create a smart grid. But the program has experienced delays and there is insufficient visibility for the timing of future orders for Gillam-FEI. However, Gillam-FEI believes that in the long run, this project could generate a multimillion euro product line that can be marketed not only in France, but in other European and North African countries.
SG&A expenses for the year were $14.7 million or 21% of revenues compared to $14.1 million and 22% of revenues last year. The higher fiscal year 2013 spending is due to a full year of SG&A expenses at FEI-Elcom. This level of SG&A expense is in line with our expectations, and as revenues increase we would expect to see the ratio of expenses to revenues to decrease.
Fiscal 2013 R&D spending was $5.7 million or about 8% of revenues compared to $3.9 million or 6% of fiscal 2012 revenues. This higher level of R&D reflects not only FEI-Elcom spending on its own product line, but also the additional FEI-Elcom resources that were applied to development of new satellite payload up/down converters and receivers.
While fiscal 2013 revenues increased over fiscal year 2012, higher operating costs, the $900,000 first quarter operating loss at FEI-Elcom, the fourth quarter asset write-down at Gillam-FEI and unanticipated order delays at FEI-Zyfer resulted in fiscal '13 operating profit of $4.7 million or 7% of revenues as compared to $6.7 million and 10% of revenues last year.
Other income, which consists of investment income offset by interest and other expenses, was a net income of $407,000 this year compared to income of $111,000 a year ago. So this yields pre-tax income, in fiscal 2013, of $5.1 million compared to last year's $6.8 million.
Now, earlier this year tax legislation was passed such that the company will realize additional tax credits as well as take advantage of previously suspended state tax NOL carryforwards. These have the effect of reducing fiscal 2013's effective tax rate to about 28% or a provision of $1.4 million.
Now, with respect to net income, last year, Frequency reversed $3.1 million of a previously established deferred tax valuation allowance. This resulted in a net tax benefit of $560,000 and increased net income by $3.1 million. That's equivalent to $0.36 per share. On an apples-to-apples basis, last year's net income would have been $4.3 million compared to this year's $3.7 million, effectively a $600,000 reduction from the prior year.
For the year, we generated positive operating cash flow of $3.1 million, and cash and marketable securities are at $21.7 million. As we indicated in the press release, in June of this 2013, we closed on a five-year $25 million revolving credit facility with JPMorgan Chase, and that will be used for working capital and acquisitions. We used the initial proceeds to repay the $6 million outstanding balance under the previous line of credit and we reclassified short-term debt to long-term.
Backlog at the end of April was $51 million compared to $57 million at the end of last year. Over 3/4 of this backlog is for long-term satellite programs.
And, finally, Stockholders equity is now at $82.2 million, up from last year's $79.1 million, and this is after the December payment of a special cash dividend of $0.20 per share, which totaled approximately $1.7 million.
I'll now turn the call back over to Martin and look forward to your questions later.
