Thank you, Michael, and thank you all for joining today's call. I will begin by reviewing our key accomplishments in 2016, the progress of our strategic repositioning and how we see the company moving forward. Michael will then review our fourth quarter and full year finance results. Walter Czarnecki will follow with a few words on OmniMetrix before opening the call out to your questions.
Over the course of 2016, Acorn successfully advanced its turnaround and strategic repositioning by focusing on our most promising businesses, eliminating some cash-consuming operations and providing needed funding. Our efforts enabled Acorn to focus on its core businesses and to put the company in a stronger position to pursue our goal of profitable growth.
To those new to Acorn, let me quickly summarize our key actions. In January of 2016, Acorn signed an agreement for a strategic sales and marketing partnership with Rafael Advanced Defense Systems Ltd. and our portfolio company, DSIT, in connection with a sale to Rafael of nearly half of Acorn's DSIT ownership. That transaction closed in April of 2016. Acorn retains a 41.2% interest in DSIT, who is an industry-leading developer of sonar and acoustic systems and software for defense, homeland security, energy and commercial markets. As a result of the sale of part of our stake in DSIT, we no longer consolidate DSIT's results in our income statement, which resulted in a significant decrease in Acorn's reported revenue in 2016. Nevertheless, we believe substantial sales and marketing synergies exist for DSIT through its new partnership with Rafael, which is a leading Israeli defense company with revenue in excess of $2 billion.
Also in April, we decided to halt operations in our GridSense subsidiary. In July, GridSense sold its asset to a subsidiary of publicly traded Franklin Electric Co. for gross proceeds of $1 million. GridSense had consumed cash and generated consistent operating losses since Acorn's investment in them in 2008, including an operating loss of $3.9 million in 2015. Its divestiture was a key priority in Acorn's turnaround, which has significantly improved Acorn's operating results and reduced our cash burn.
Acorn also made significant progress during 2016 in reducing operating costs both at the corporate and subsidiary level, and we expect to see a full year's benefit from these actions in 2017. While our strategic initiatives have resulted in lower reported revenue, they have enabled us to deliver a far stronger cash flow and bottom line performance versus last year. However, it's clear that the transformation of Acorn is far from complete.
Going forward, we remain focused on scaling our OmniMetrix business, which ties into core industry trends seeking to leverage Internet of Things technology to manage and protect high-value industrial assets while also lowering maintenance costs. Importantly, more than half of OmniMetrix revenue is derived from recurring monitoring and maintenance contracts, which provide a stable and growing base of cash flow with very attractive margins.
We are pleased with OmniMetrix progress in the past year as we implemented some important changes, including hiring 2 new salespeople and overhauling the finance department. We are confident these and other initiatives will lead to improved financial performance in the longer term. OmniMetrix' CEO, Walter Czarnecki, will provide more color on this business later in the call.
We will continue our efforts to grow this business organically as well as seek and evaluate potential acquisition targets to accelerate revenue growth in monitoring or other areas where we can identify similar strong business models with potential to enhance shareholder value.
We also still own 41.2% of DSIT after selling nearly half of our holdings last year. This remaining investment has a book value of $5.7 million based primarily on the prior sale price adjusted for net earnings since the transaction date. In 2016, DSIT had a very good year, with revenues up 25% and EBITDA nearly tripling. Based on our current backlog, we anticipate another strong year ahead.
In addition to DSIT and OmniMetrix, Acorn has a federal net operating loss carryforward position in excess of $60 million, which is another potentially strategic asset. These assets, combined with the strength and expertise of our team, represent significant value that we believe should become better reflected in our share price as we advance our turnaround strategy. Our objective is to move Acorn towards sustainable profitability and shareholder value creation, and we remain optimistic regarding our prospects to get there.
Finally, in an effort to keep Acorn adequately funded as we work to transform the business, we were successful in securing $1.9 million in loan commitments from our Board of Directors. After reviewing a number of term sheets, these commitments represented the lowest-cost and most flexible source of capital available to Acorn.
In February of 2017, we received $900,000 in initial funding, and we have a commitment for an additional $1 million in funding to be provided later in the year if alternative sources of financing are not secured. It is expected that these borrowings will be repaid from the proceeds from the planned monetization of our remaining DSIT ownership interest.
With that, I'll hand the call back to Michael to review our fourth quarter and full year financials. Michael?
