NOTE 1— BASIS OF PRESENTATION
The accompanying unaudited condensed consolidated financial statements of Acorn Energy, Inc. and its subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes req uired by accounting principles generally accepted in the United States of America for complete consolidated financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the six month period ended June 30, 2013 are not ne cessarily indicative of the results that may be expected for the year ending December 31, 2013. All dollar amounts in the notes to the condensed consolidated financial statements are in thousands except for per share data.
Certain reclassifications have been made to the Company's condensed consolidated financial statements for the six month period ended June 30, 2012 to conform to the current period's condensed consolidated financial statement presentation. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012.

NOTE 2—RECENT AUTHORITATIVE GUIDANCE
Effective January 1, 2013, the Company adopted the authoritative guidance, issued by the Financial Accounting Standards Board (“FASB”) in February, 2013, related to reclassifications out of accumulated other comprehensive income (“OCI”). Under this update, an entity is required to report, in one place, information about reclassifications out of accumulated OCI and to report changes in its accumulated OCI balances. For significant items reclassified out of accumulated OCI to net income in their entirety in the same reporting period, reporting is required about the effect of the reclassifications on the respective line items in the statement where net income is presented. For items that are not reclassified to net income in their entirety in the same reporting period, a cross reference to other disclosures currently required under GAAP is required in the notes to the financial statements. The adoption of this guidance had no impact on the Company's consolidated financial statements.
There have been no other recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2013, that are of material significance, or have potential material significance, to the Company.

NOTE 3— INVESTMENTS IN US SEISMIC SYTEMS, INC. ("USSI")
On February 28, 2013, the Company entered into a new Stock Purchase Agreement with USSI pursuant to which the Company made a payment to USSI of $2,500 to purchase additional shares of USSI Preferred Stock. In May, the Company made another payment of $2,500 to purchase additional shares of USSI Preferred Stock. The USSI Preferred Stock is the same class of shares that the Company acquired in 2012 and provides that upon any future liquidation of USSI, to the extent funds are available for distribution to USSI's stockholders after the satisfaction of any USSI liabilities at that time, USSI would first repay the Company for the purchase price of its USSI Preferred Stock. Thereafter, the Company would receive a further payment for such shares ratably with all other USSI Common Stock holders as though the Company's shares of USSI Preferred Stock were the same number of shares of USSI Common Stock.
Following the May payment to USSI, the Company owned approximately 95.6% of USSI on an as converted basis (which amount would be diluted to approximately 87.9% if all options which could be awarded under USSI's 2012 Stock Purchase Plan were awarded and exercised).

NOTE 4— RESTRUCTURING AND RELATED CHARGES
During the second quarter of 2013, following a change in its management, the Company's GridSense segment made a decision to restructure operations in both its USA and Australian entities. This action was taken primarily in order to improve efficiency based on GridSense's revenue mix and skills mix. Accordingly, GridSense recorded a restructuring charge of $302 related to severance and other termination benefits for 17 employees whose positions were made redundant both in the United States and in Australia. In addition, in connection with downsizing its Australian operations, GridSense decided to move its operations to a smaller facility and recorded a restructuring charge of $101, consisting of contractual rental commitments and related moving costs. In connection with that move, GridSense recorded a loss of $39 reflecting the remaining book value of abandoned fixed assets. Following the restructuring, GridSense's Australian operations no longer have a production line and have minimal research and development activities. All product production and development will take place at GridSense's U.S. operations facility in Sacramento. As a result of the cessation of production activities in Australia, GridSense also recorded a provision of $152 related to products which had been produced in Australia, but will no longer be produced or supported by U.S. operations.
The following table summarizes the restructuring charges during the six months ended June 30, 2013:

Employee severance and termination benefits |  | $ | 302 |
Facilities costs |  | 101 |
Abandonment of fixed assets |  | 39 |
Inventory obsolescence |  | 152 |
Total |  | $ | 594 |

The following table presents activity during the six months ended June 30, 2013 related to GridSense's restructuring:

|  | Employee severance and termination benefits |  | Facilities |  | Inventory and fixed asset impairments |  | Total
Balance at December 31, 2012 |  | $ | — |  |  | $ | — |  |  | $ | — |  |  | $ | — |

(d) | Warrants

The Company previously issued warrants at exercise prices equal to or greater than market value of the Company’s common stock at the date of issuance. A summary of warrant activity follows:

|  | Number of Warrants (in shares) |  | Weighted Average Exercise Price Per Share |  | Weighted Average Remaining Contractual Life
Outstanding at December 31, 2012 |  | 28,750 |  |  | $ | 3.68 |  |  |

Outstanding at June 30, 2013 |  | 23,000 |  |  | $ | 3.68 |  |  | 2.5 years

During the six months ended June 30, 2013, 2,954 warrants were exercised and 2,796 warrants were forfeited in connection with the “net exercise” of 5,750 warrants. In a net exercise of a warrant, the Company does not require a payment of the exercise price of the warrant from the warrant holder, but reduces the number of shares of common stock issued upon the exercise of the warrant by the smallest number of whole shares that has an aggregate fair market value equal to or in excess of the aggregate exercise price for the warrants covered by the warrants exercised. The 5,750 warrants which were exercised under this method had a weighted average exercise price of $3.68 per share.

NOTE 11 — SUBSEQUENT EVENTS
Acorn Investment in DSIT
Effective July 1, 2013, the Company entered into a new Stock Purchase Agreement with DSIT pursuant to which the Company converted a prior loan into additional ordinary (common) shares of DSIT. The Company converted $2,800 in advances and loans into DSIT's Participating Preferred Stock (the “DSIT Preferred Stock”). At the closing, Acorn purchased an additional $800 of DSIT Preferred Stock and committed to purchasing an additional $1,400 of DSIT Preferred Stock as follows:

• | $300 upon the earlier of October 1, 2013 or the completion of a certain milestone in a Transfer of Engineering Data Agreement (“TED”) between DSIT and USSI which is currently being negotiated.

• | $500 on October 1, 2013.

• | $300 upon the earlier of January 1, 2014 or the completion of a certain milestone in the TED agreement.

• | $300 upon the earlier of April 1, 2014 or the completion of a certain milestone in the TED agreement.

The DSIT Preferred Stock provides that upon any future liquidation of DSIT, to the extent funds are available for distribution to DSIT's stockholders after the satisfaction of any DSIT liabilities at that time, DSIT would first repay the Company for the purchase price of our DSIT Preferred Stock. Thereafter, the Company would receive a further payment for such shares ratably with all other DSIT ordinary stock holders as though the Company's shares of DSIT Preferred Stock were the same number of DSIT ordinary shares.
The Company currently owns approximately 88.3% of DSIT on an as converted basis. If all the above investments are made, the Company would own approximately 89.1% of DSIT on an as converted basis. If all the options to purchase all shares of DSIT ordinary stock available under the DSIT Option Plan are granted and exercised and all above investments are made, the Company would own approximately 78.8% of DSIT on a fully diluted as converted basis.

RECENT DEVELOPMENTS
Acorn Investment in DSIT
Effective July 1, 2013, Acorn entered into a new Stock Purchase Agreement with DSIT pursuant to which Acorn converted a prior loan into additional ordinary (common) shares of DSIT. Acorn also converted $2.8 million in advances and loans into DSIT's Participating Preferred Stock (the “DSIT Preferred Stock”). At the closing, Acorn purchased an additional $800,000 of DSIT Preferred Stock and committed to purchasing an additional $1.4 million of DSIT Preferred Stock as follows:

• | $300,000 upon the earlier of October 1, 2013 or the completion of a certain milestone in a Transfer of Engineering Data Agreement (“TED”) between DSIT and USSI which is currently being negotiated.

• | $500,000 on October 1, 2013.

• | $300,000 upon the earlier of January 1, 2014 or the completion of a certain milestone in the TED agreement.

• | $300,000 upon the earlier of April 1, 2014 or the completion of a certain milestone in the TED agreement.

The DSIT Preferred Stock provides that upon any future liquidation of DSIT, to the extent funds are available for distribution to DSIT's stockholders after the satisfaction of any DSIT liabilities at that time, DSIT would first repay Acorn for the purchase price of its DSIT Preferred Stock. Thereafter, Acorn would receive a further payment for such shares ratably with all other DSIT ordinary stock holders as though Acorn's shares of DSIT Preferred Stock were the same number of DSIT ordinary shares.
Acorn currently owns approximately 88.3% of DSIT on an as converted basis. If all the above investments are made, Acorn would own approximately 89.1% of DSIT on an as converted basis. If all the options to purchase all shares of DSIT ordinary stock available under the DSIT Option Plan are granted and exercised and all above investments are made, Acorn would own approximately 78.8% of DSIT on a fully diluted as converted basis.
GridSense Order
In June 2013, GridSense received a purchase order valued in excess of $1 million for 700 units of its Distribution IQ TM and Line IQ® units that are each enabled by Grid InSite TM software. The order came from a major national utility based on a partnership with a regional smart grid company and is expected to be processed and shipped in the third quarter of 2013.
GridSense and OmniMetrix under Unified Management
On July 31, 2013, Acorn announced that Joe Musanti will be named President and CEO of a new company which will operate both its GridSense and OmniMetrix businesses in order to leverage the engineering and marketing activities of Gr idSense and OmniMetrix into a single operating unit. Mr. Musanti was named President and CEO of OmniMetrix following Deena Redding's departure in July. GridSense and OmniMetrix will continue to report operating results in their own respective segments. This decision will allow Mr. Musanti to exploit synergies that exist in multiple administrative functions between both companies and that are expected to accelerate a path to market for their products, grow sales and attain critical mass.

As OmniMetrix's activities were acquired in February 2012, there are only partial comparative results reported for these activities for the six month period ended June 30, 2012.
The following analysis should be read together with the segment information provided in Note 10 to the interim unaudited condensed consolidated financial statements included in this quarterly report.
DSIT Solutions
DSIT revenues of $6.8 million in the first six months of 2013 were unchanged as compared to the first six months of 2012 while gross profit and gross margin both increased slightly. Operating income decreased, primarily as a result of increased research and development costs during the year. DSIT's revenues of $3.5 million for the second quarter of 2013 represents a decrease of approximately $0.3 million or 7% as compared to the second quarter of 2012. In addition, second quarter 2013 revenues reflected an increase of $0.1 million or 4% compared to first quarter 2013 revenues of $3.3 million.
Revenues in our Energy & Sonar Security Solutions segment were unchanged at $6.2 million for both the first six months of 2013 and the first six months of 2012. Revenues from DSIT's other IT and consulting activities which are included in Acorn's Other segment activities decreased slightly in 2013 (from $0.7 million to $0.6 million). Second quarter 2013 Energy & Sonar Security Solutions revenues of $3.1 million were $0.3 million or 8% lower than second quarter 2012 revenues due to slowdown in revenue recognition in one of the company's major projects as it nears completion without a similar size project replacing it in the company's backlog. Second quarter 2013 revenues from DSIT’s other IT and consulting activities were relatively unchanged from 2012 to 2013.
DSIT's gross profit in the first six months of 2013 increased by approximately $0.1 million or 4% compared to the gross profit of the first six months of 2012. The increase in gross profit was attributable to a slight increase in the gross margin over the period. Gross margin increased from 37% in the first six months of 2012 to 38% in the first six months of 2013. The increase in the gross margin in the first six months of 2013 was due to the mix of projects worked on during the quarter. Second quarter 2013 gross margin of 37% reflected a decrease from 40% in the second quarter of 2012 and from 39% in the first quarter of 2013. The decrease in the gross margin in the second quarter of 2013 compared to the second quarter of 2012 and the first quarter of 2013 was due to increased projected installation costs for one of the company's AquaShield TM Diver Detection Sonar projects.

During the first six months of 2013, DSIT recorded approximately $0.7 million of Research and Development (R&D) expense, an increase of approximately $0.3 million compared to the first six months of 2012. DSIT's increased R&D expense is related to work on the joint development (with USSI) of the PAUSS next generation integrated passive/active threat detection system for underwater site protection. In 2013, such R&D expense is net of approximately $0.2 million of participation from the Israel-U.S. Binational Industrial Research and Development ("BIRD") Foundation in the project. In addition, DSIT is continuing to expend resources to expand DSIT's portfolio of products to include land-based security fiber-optic solutions.
DSIT is currently negotiating with USSI a TED agreement whereby DSIT would receive from USSI an exclusive world-wide license to use USSI technology to provide systems, devices, installations and methods for monitoring ground sites, facilities, locations and perimeters against land-based security threats for government and non-government customers for defense, security or military and safety applications.
During the first six months of 2013, DSIT recorded approximately $1.6 million of selling, general and administrative (SG&A) expense with approximately $0.8 million being recorded in both the first and second quarters of 2013. The 2013 SG&A expense is approximately $0.2 million above the SG&A recorded in the first six months of 2012. The increase compared to the first six months of 2012 is attributable to increased salary costs and increased marketing expenses. The $0.8 million of SG&A in the second quarter of 2013 is marginally ($60,000) above second quarter 2012 SG&A primarily due to increased payroll expenses.
At December 31, 2012, DSIT had a project backlog of approximately $9.6 million. During the first six months of 2013, we received new orders totaling approximately $2.8 million and at the end of June 2013 had a backlog of approximately $6.2 million.
DSIT’s growth and profitability for the balance of 2013 is dependent upon pending orders for sonar systems. DSIT is currently awaiting the results of a bid process for a major multi-million dollar project. Results of the bid process are expected shortly, though we have no assurance that we will win the project or that if we do win the project, that we will be able to perform
enough work to be able to recognize significant amounts of revenue over the balance of 2013. While DSIT has a significant pipeline, most of its major projects come after a lengthy sales cycle over which it has little control. Should this project not be received or its receipt significantly delayed, DSIT's revenues and profitability will likely decrease over the short term.
In July 2013, DSIT's renewed its lease for its operating facilities in the Tel Aviv, Israel metropolitan area which had expired in August 2012. The current lease expires in June 2016 and has an annual rent of approximately $285,000. DSIT has an option to renew the lease for an additional three year period with an increase of 6% in the annual rent.
Effective July 1, 2013, Acorn entered into a Stock Purchase Agreement with DSIT pursuant to which Acorn converted a prior loan into additional ordinary (common) shares of DSIT. Acorn also converted $2.8 million in advances and loans into DSIT's Participating Preferred Stock (the “DSIT Preferred Stock”). At the closing, Acorn purchased an additional $800,000 of DSIT Preferred Stock and committed to purchasing an additional $1.4 million of DSIT Preferred Stock as follows:

• | $300,000 upon the earlier of October 1, 2013 or the completion of a certain milestone in a TED agreement between DSIT and USSI which is currently being negotiated.

• | $500,000 on October 1, 2013.

• | $300,000 upon the earlier of January 1, 2014 or the completion of a certain milestone in the TED agreement.

• | $300,000 upon the earlier of April 1, 2014 or the completion of a certain milestone in the TED agreement.

The DSIT Preferred Stock provides that upon any future liquidation of DSIT, to the extent funds are available for distribution to DSIT's stockholders after the satisfaction of any DSIT liabilities at that time, DSIT would first repay Acorn for the purchase price of its DSIT Preferred Stock. Thereafter, Acorn would receive a further payment for such shares ratably with all other DSIT ordinary stock holders as though Acorn's shares of DSIT Preferred Stock were the same number of DSIT ordinary shares.
Acorn currently owns approximately 89.1% of DSIT on an as converted basis. If all the above investments are made, Acorn would own approximately 90.2% of DSIT on an as converted basis. If all the options to purchase all shares of DSIT ordinary stock available under the DSIT Option Plan are granted and exercised and all above investments are made, Acorn would own approximately 80.6% of DSIT on a fully diluted as converted basis.
DSIT intends to use these funds from Acorn to support its R&D activities in order to expand DSIT's portfolio of products and expense into land-based security fiber-optic solutions as well as to expand its sales and marketing activities.

GridSense
In the first six months of 2013, GridSense reported revenues of $2.5 million, an increase of $0.6 million (30%) compared to first six month 2012 revenues of $1.9 million. Second quarter 2013 revenues of $0.9 million were slightly (6%) below second quarter 2012 revenues of $1.0 million. Second quarter 2013 revenues represents a decrease of $0.6 million (40%) compared to first quarter 2013 revenues of $1.5 million. The increase in 2013 revenues was attributable to increased revenues from GridSense's U.S. operations which saw its revenues increase from $1.1 million in 2012 to $1.6 million in 2013. Revenues from GridSense's Australian operations were relatively unchanged in the first six months of 2013 compared to the same period in 2012 at $0.8 million. The increased revenue in the United States was attributable to an order GridSense was awarded in late 2012 for 800 Transformer IQ® units from a California based investor owned utility. This order was partially fulfilled in 2012 with the balance being completed in the first quarter of 2013. The decrease in second quarter revenues as compared to first quarter 2013 revenues was due to the fulfillment of this order in the first quarter. Australian revenues in 2013 remain steady attributable to purchases related to the company's PowerMonic® product.
While GridSense sees some improvement in the overall business environment in the utility industry and expects utility spending to increase in future quarters, the timing of such spending on products such as those that GridSense provides cannot be predicted with certainty due to the sales cycle of electric utilities which is typically long and requires much technical and application support. To address these long sales cycles, GridSense has expanded its customer pilot programs from just a handful in 2011 to over 45 ongoing pilots around the globe. We plan to focus our continued sales efforts in 2013 and into 2014 only on those products that have already shown the most traction in the marketplace such as the Transformer IQ®, the Line IQ® and GridInSite TM and to work towards a goal of being cash flow neutral by year-end.
In June 2013, GridSense secured an order from a major national utility based on a partnership with a regional smart grid company. The order, valued in excess of $1.0 million, for 700 units of its Distribution IQ TM and Line IQ® units that are each enabled by Grid InSite TM software. This order represents another conversion of a pilot to an initial commercial order involving over 700 units. As noted above, in the first quarter of 2013, GridSense finalized shipment of an order in excess of $750,000 from a California based investor owned utility. GridSense anticipates fulfilling the entire order during the third quarter of 2013.
GridSense's gross profit in the first six months of 2013 increased by approximately $0.2 million or 29% compared to first six months 2012 gross profit and decreased by approximately $0.3 million compared to first quarter 2013. The increase in gross profit was attributable to the abovementioned increase in revenues with gross margin percentage virtually unchanged from 2012. Gross margins remained relatively steady in the first half of 2013 at 42% as compared to 43% in the first half of 2012 and 43% in the first quarter of 2013. We expect gross margins to continue at current or higher levels as we continue to work towards managing inventory more efficiently, improving forecasting for purchasing and procurement, and reducing production cycle times.
Following the resignation of GridSense's former CEO, Lindon Shiao, in May 2013, Joe Musanti who had been serving as Chief Financial Officer and Chief Operating Officer of GridSense was appointed as President and CEO of GridSense. Following his appointment, Mr. Musanti undertook a number of cost cutting measures in GridSense's U.S. and Australian operations as well as working to improve inventory management and customer service and alignment of engineering and sales. He has also overseen the restructuring of both the Australian and US operations with further plans to continue to identify areas where cost savings might be implemented in order to position the company to meet its cash flow goals. This action was taken primarily in order to improve efficiency based on GridSense's revenue mix and skills mix. As a result, during the second quarter, GridSense recorded a restructuring charge of $302,000 related to severance and other termination benefits for 17 engineering and administrative employees whose positions were made redundant both in the United States and in Australia. Following the restructuring, GridSense's Australian operations will no longer have a production line and will have minimal research and development activities. GridSense's U.S. operations will also have a reduced engineering staff and will have reduced research and development activities. In addition, following the decision to downsize its Australian operations, GridSense decided to move its operations to a smaller space and recorded a restructuring charge of $101,000 consisting of contractual rental commitments and related moving costs. In connection with the move to a smaller space, GridSense also recorded a loss of $39,000 reflecting the remaining book value of abandoned fixed assets. As a result of the cessation of production activities in Australia, GridSense recorded a provision of $152,000 related to products which had been produced in Australia, but will no longer be produced and supported by U.S. operations. By the end of July 2013, GridSense had completed the changes implemented in GridSense's total restructuring charge in the second quarter of 2013 was $594,000.
In the first six months of 2013, GridSense recorded $1.4 million of R&D expense as compared to $0.7 million in the same period of 2012. The increased R&D expense is due to the growth in GridSense's engineering team in 2012 in order to accelerate the development of some key products that GridSense believes will lead to the generation of new revenues. Second quarter R&D expense was $0.7 million following $0.7 million in the first quarter of 2013. As noted above, following the downsizing
28

Table of Contents
of GridSense's Australian operations and reduced engineering staff in the U.S., GridSense expects that R&D expense going forward will be significantly lower than in previous quarters.
During the first six months of 2013, GridSense recorded approximately $1.8 million of SG&A expense representing a decrease of approximately $0.3 million (16%) compared to the first six months of 2012 SG&A expense. Second quarter 2013 SG&A expense reflected a decrease of $0.3 million or (31%) compared to first quarter 2013 SG&A expense. The decreased SG&A costs for both periods noted is due to headcount reduction due to role consolidation and cost cutting measures that were commenced in late 2012 and continued into 2013. We expect that this trend will continue through 2013.
Acorn continues to provide funds for GridSense's working capital needs. In the period from January 1 to July 31, 2013, Acorn provided GridSense with $1.5 million for its working capital needs (the total amount of the "GridSense Commitment" - see Liquidity and Capital Resources) plus an additional $480,000 to fund the costs of the restructuring noted above. If GridSense is able to meet its sales goals for the second half of 2013, we believe that no additional funding would be required. In August 2012, GridSense signed a Loan and Security Agreement with a bank to provide it with up to a $1.0 million revolving line of credit (subject to a calculated borrowing base). The outstanding balance as of June 30, 2013 was $171,000. The line-of-credit is subject to certain financial and other covenants. At June 30, 2013, GridSense was not in compliance with its financial covenants at June 30, 2013 due to the effect of the restructuring. GridSense has received a covenant waiver from its bank.The availability and amount of any additional investment from us in GridSense may be limited by the working capital needs of our corporate activities and other operating companies.
On July 31, 2013, GridSense had cash on hand of approximately $0.1 million. We have no assurance that GridSense will increase its sales or reduce its need for additional financing to support its working capital needs. Additional working capital support may be in the form of an additional or expanded bank line, new investment by others, additional investment or loans by Acorn, or a combination of the above. There is no assurance that GridSense will be able to obtain an additional or expanded line-of-credit or other support in sufficient amounts, in a timely manner or on acceptable terms. The availability and amount of any additional investment from us in GridSense may be limited by the working capital needs of our corporate activities and other operating companies.
OmniMetrix
In accordance with applicable accounting standards, we began consolidating the results of OmniMetrix beginning February 15, 2012, the date we acquired OmniMetrix. Accordingly, there are only partial comparative results reported for OmniMetrix for the six month period ended June 30, 2012.
In the first half of 2013, OmniMetrix recorded revenues of $1.1 million ($804,000 in its Power Generation Monitoring ("PG") segment and $257,000 in its Cathodic Protection ("CP") segment) as compared to $157,000 recorded in the first half of 2012 following our acquisition. The increase in revenues is driven by the increase in the number of units being monitored. Second quarter 2013 revenues of $528,000 were marginally below first quarter 2013 revenues of $533,000.
During the second quarter of 2013, a customer with whom OmniMetrix had a significant on-going relationship at the time of Acorn's acquisition of OmniMetrix in February 2012 (over 1,000 power generation units were then being monitored for that customer), indicated that they would be disconnecting their monitoring units over a period of time. At the time of the acquisition, an amortizing customer relationship intangible asset of approximately $1.3 million was recorded with respect to that customer. Following the decision to disconnect their monitoring units, OmniMetrix recorded an impairment of the intangible asset of approximately $1.1 million. Through June 30, 2013, 252 of this customer's units have been disconnected.
As of January 1, 2013, OmniMetrix, had 2,758 PG units generating revenue. Such units have been shipped and activated (revenue recognition begins only following the activation of a shipped unit). During the first half of 2013, OmniMetrix added an additional 834 units (net of 292 units removed from service) to bring the total number of PG units generating revenue to 3,592; an increase of 30% over the past six months. The number of units reported above are on a different basis than previously reported units as we believe that reporting revenue generating units to be more meaningful than units in service which may or may not be actively generating revenue.
Since our acquisition, and primarily towards the end of 2012, OmniMetrix has engaged in developing and implementing a major marketing and promotion program to increase the penetration rate of its PG monitoring products into the market. We viewed the growth in PG units generating revenue in the first quarter of 2013 (512 units, net of two disconnects) as an initial indication of our marketing and promotion program gaining traction. However, in the second quarter of 2013, the growth in the
29

Table of Contents
number of units generating revenue slowed down (322 units, net of 290 disconnects of which 252 were related to a single customer - see above). While we are continuing with this program, we are also refocusing our marketing efforts on several strategic initiatives.
Our end-user customers (in additional to generator dealers) tend to recognize significant value in our offering. Accordingly, we have increased our focus on end-user customers in our marketing strategy. In conjunction with our increased focus on end-user customers, we have created a five-person lead generation team that makes outbound calls to potential end-user customers as well as to generator dealers. In addition, in January 2013, the EPA finalized amendments to the National Emissions Standards for Hazardous Air Pollutants for stationary reciprocating internal combustion engines (generators). Now every commercial generator over a certain size needs to collect and report run times and annual emissions or face significant civil penalties. Consequently, some end-user customers as well as environmental engineering firms, see significant value in our offering due to our ability to assist end-user customers in complying with such environmental regulations. As a result, we have increased our marketing efforts to highlight this value we provide to our customers. We are currently providing reports and information to end-user customers to assist them in their environmental compliance, and we have received positive feedback from these customers.
First half 2013 gross profit was approximately $600,000 reflecting a gross margin of 57% on revenues compared with a negative gross profit of $29,000 in the first half of 2012. Second quarter gross profit of $273,000 reflected a gross margin of 52%, down from the first quarter's gross margin of 62%. The decrease in the gross margin was due to an increased number of units given away. The gross margin continues to be driven by margins on monitoring revenue which was 67% during the period. As monitoring revenue continues to grow, we expect these margins to increase in the long term as certain fixed costs (amortization of acquired technology) are spread over a greater revenue base and the deferred costs associated with the provision of units to certain customers below cost are fully amortized.
During the first half of 2013, OmniMetrix recorded approximately $268,000 of R&D costs. R&D costs increased slightly in the second quarter to $148,000 from $120,000 in the first quarter of 2013. We anticipate that these costs will continue at or above recent levels as we expand our product offering and develop solutions for other markets.
During the first half of 2013, OmniMetrix recorded approximately $2.4 million of SG&A costs of which approximately $1.0 million was related to sales and marketing. Such costs were significantly above first half 2012 SG&A costs of $834,000 ($226,000 in sales and marketing) since our acquisition of OmniMetrix in February of 2012. The growth in SG&A costs reflects the investment in marketing and back-office infrastructure since our acquisition. Second quarter 2013 SG&A costs of $1.2 million were slightly above first quarter 2013 SG&A costs reflecting the impact of our move to our new facilities. We anticipate that our SG&A costs have stabilized and will continue near or at current levels over the balance of 2013 as we believe we developed our infrastructure to accommodate expected growth and expand our market presence.
In July 2013, Joe Musanti was named President and CEO of OmniMetrix following the departure of Deena Redding.
OmniMetrix currently has no other sources of financing other than its internally generated sales and investments by Acorn. To support OmniMetrix's marketing and promotion program, Acorn has committed to invest $3.0 million in OmniMetrix during 2013, of which $2.0 million has been invested through July 31, 2013 with the balance expected to be funded over the remainder of 2013 as needed. Acorn's remaining investment in OmniMetrix in 2013 is expected to be for working capital and the continued development of OmniMetrix's network operation center.
As of July 31, 2013, OmniMetrix had cash on hand of approximately $0.1 million. OmniMetrix will continue to need additional financing for working capital after we complete our $3.0 million additional investment. The level of additional financing will be dependent upon the level of penetration by OmniMetrix into the power generation monitoring market. Additional financing for OmniMetrix may be in the form of a bank line, new investment by others, a loan or investment by Acorn, or a combination of the above. OmniMetrix has begun discussions with a bank to provide working capital financing: however, there is no assurance that such financing from the bank or any other party will be available in sufficient amounts, in a timely manner or on acceptable terms. The availability and amount of any additional investment from us in OmniMetrix may be limited by the working capital needs of our corporate activities and other operating companies.
USSI
In the first half of 2013, USSI received an evaluation order from a super-major oil company for USSI's down-hole seismic fiber‐optic array sensing system. This system was designed for use in a permanent down-hole monitoring application to enable on-going and high-resolution sub-surface imaging of oil and gas reservoirs. Following USSI's delivery of the system in the second quarter, it was used in a competitive, side-by-side, full scale field evaluation by the customer. The supermajor informed USSI that
30

Table of Contents
they were using this competitive process to select the technology that will be used for monitoring all of their future unconventional wells. As a result of the competition, the supermajor selected USSI to move on to the next phase of the project.
In the first six months of 2013, USSI reported revenues of $635,000, a decrease of $448,000 (41%) compared to first six months 2012 revenues of $1.1 million. Second quarter revenues of $310,000 reflect decreases of $15,000 (5%) and $652,000 (68%) as compared to first quarter 2012 and second quarter 2012 revenues, respectively. The decreased revenues for each period is due to the timing of the delivery of USSI's sensor systems - in particular the delay in the delivery of a system to SR2020 on a $1.0 million project. This delay was caused by a manufacturing defect in the high pressure seals used to prevent leakage of high temperature well fluids into the downhole sensor housings. USSI detected the problem during internal qualification testing and is now in the process of qualifying two new suppliers for these seals. Final qualification of the new seals is expected to be completed shortly. It is now expected that this delivery will be made in the third quarter.
In the first six months of 2013, gross profit continued to be negative ($850,000) as it was in the first six months of 2012 ($605,000). The negative gross profit is primarily due to large amounts of up front non-recurring engineering ("NRE") design costs that accompanied USSI's other proof of concept projects in 2012 and continue to do so in 2013. Approximately $280,000 of the negative gross profit was attributable to the write-off of inventory to cost of sales.
USSI is continuing to work to develop cost cutting measures for the manufacturing of its commercial products, including investment in equipment that will make manufacturing more efficient and improving the production process and product designs that will ultimately result in fewer man-hours required for each product sold. We expect that the impact of these improved production processes and product designs will produce improved gross margins in the second half of 2013. We believe that upon receipt of follow-up orders on our proof-of-concept projects, we will realize additional improvements in gross margins as these efficiencies in production are expected to be greater in larger projects where we anticipate being able to utilize our new interrogator technology.
In the first half of 2013, USSI recorded approximately $1.7 million of R&D expense, slightly less than the $1.8 million of R&D expense recorded in the first half of 2012. Second quarter R&D expense of $0.8 million was slightly below the $0.9 million of R&D expense recorded in the first quarter of 2013 and the second quarter of 2012. We expect R&D expense to continue to approximately those of the levels seen in the first and second quarters of 2013 as USSI continues to internally develop more efficient production versions of its current products and adds additional engineering headcount to continue its development of multiple product offerings.
In the first half of 2013, USSI recorded approximately $1.6 million of SG&A expense representing an increase of approximately $0.2 million (16%) compared to the first half of 2012. The increase from the first half of 2012 is due to increases in salary expense as a result of added headcount and increased spending relating to sales and marketing activities. Second quarter SG&A expense of approximately $0.8M was relatively unchanged from first quarter 2013 SG&A expense. USSI does not expect SG&A expense to materially change in the coming quarters.
In July 2013, USSI signed an agreement to lease an additional 8,600 square feet of space contiguous to its facilities in Chatsworth, California. The additional space is expected to be used for production of anticipated commercial orders.
As at June 30, 2012, USSI's backlog of projects was approximately $1.0 million which is primarily comprised of its SR2020 proof-of-concept project. USSI anticipates recognizing the revenue associated with this project in the third quarter of 2013. Actual revenue recognition for this project is dependent upon the timing of the delivery. We continue to anticipate significant growth in orders, particularly from new customers related to our 4D reservoir and shale gas monitoring systems following the demonstrations performed during 2013 (such as the supermajor noted above) and prior years as well as follow-on projects from our current proof-of-concept projects.
We believe that each of these proof-of-concept projects has the potential for annual multi-million dollar follow-up orders as early as the end of 2013. During 2013, we grew our employee base from 43 full-time employees (inclusive of consultants) at the end of 2012 to 58 full-time employees (inclusive of consultants) as of July 31, 2013. Other than production staff, we do not anticipate further significant growth in personnel.
We expect that USSI will continue to require working capital support while it continues to transition from development to production and as it continues to work on refining its manufacturing capabilities. During 2013 we invested $5.0 million in USSI to support its working capital requirements under our 2013 USSI Purchase Agreement. We expect that USSI's working capital requirements will lessen following the anticipated receipt of the second order from the supermajor and upon receipt of commercial orders. We expect that we will be investing additional funds in USSI before year-end, though the amounts to be invested will be dependent on USSI's needs at that time.

While USSI reached agreement with a bank for a $1 million line-of-credit in 2012, we have no assurance that USSI's future capital needs will not exceed the amount of the credit line or that USSI will generate sufficient cash flow in the future to fund its operations in the absence of additional funding sources. Furthermore, we have no assurance whether and to what extent USSI will have access to the entire $1.0 million bank facility given that the availability is subject to certain financial and other covenants. USSI may need additional funds if revenues fail to meet projections or to fund a rapid expansion to meet product demand, respond to competitive pressures or acquire complementary products, businesses or technologies. Additional financing for USSI may be in the form of an expanded bank line, new investment by others, a loan or investment by Acorn, or a combination of the above. While USSI has begun discussions with its bank on an expanded bank line, we have no assurance that additional financing from the bank or other sources will be available on terms acceptable to USSI. The availability and amount of any additional investment from us in USSI may be limited by the working capital needs of our corporate activities and other operating companies.
Corporate
Corporate general and administrative expense of $2.8 million in the first half of 2013 reflected a slight increase (less than $50,000) to the expense in the first half of 2012. Second quarter corporate general and administrative expense of $1.4 million was virtually unchanged from first quarter corporate general and administrative expense and was slightly ($0.1 million) more than second quarter 2012 corporate general and administrative expense.
First half 2012 corporate general and administrative expense included approximately $300,000 of professional fees and costs incurred associated with our acquisition of OmniMetrix. In 2013, these one-time costs were replaced by an increase in non-cash stock compensation expense (an increase of approximately $350,000 in 2013 compared to 2012). In coming quarters, we expect our corporate general and administrative costs to approximate our current levels or decrease slightly as we expect to incur less investor relation expenses going forward.
As of July 31, 2013, the Company's corporate operations (not including cash at any of our subsidiaries) held a total of approximately $9.7 million in cash and cash equivalents ($6.0 million in U.S. banks and $3.7 million in Israeli banks (all of which can be repatriated without any tax consequence). Acorn anticipates receipt of its Federal income tax refund of approximately $1.7 million during the fourth quarter of 2013. We believe that our current cash plus the cash expected to be generated from operations and borrowing from available lines of credit, if necessary, will provide sufficient liquidity to finance the operating activities of Acorn and the operations of its operating subsidiaries for at least the next 12 months. In order to position ourselves to take advantage of potential market expansion or complementary acquisitions for our existing businesses, we are contemplating whether and on what terms we may offer additional securities for sale in the future. We currently expect that we may conduct such an offering prior to the end of 2013, the amount and terms of which cannot be determined at this time.

Revenues. Revenues in the first half of 2013 increased by $1.0 million or 10% from $10.0 million in the first half of 2012 to $10.9 million in the first half of 2013. The increased revenues was driven primarily by increased revenues at OmniMetrix whose reported revenues increased by $0.9 million to $1.1 million compared to first half 2012 revenues of $0.2 million since our acquisition of them in February of 2012 and GridSense revenues which increased by $0.6 million (30%) to $2.5 million compared to first half 2012 revenues of $1.9 million. DSIT's revenues ($6.8 million) were unchanged in 2013 as compared to 2012 while USSI's revenues decreased by $0.4 million (41%) to $0.6 million compared to first half 2012 revenues of $1.1 million.
OmniMetrix recorded revenues of $1.1 million were comprised of $0.8 million in its PG segment and $0.3 million in its CP segment as compared to $115,000 and $43,000, respectively for 2012. The increase in revenues is driven by the increase in the number of units being monitored. The increase in GridSense revenues was due to increased sales activity from U.S. operations which was attributable to the fulfillment of an order for 800 Transformer IQ® units from a California based investor owned utility that was received in late 2012. At DSIT, revenues in its Energy & Sonar Security Solutions segment increased slightly (from $6.1 million to $6.2 million). This increase was offset by a slight decrease in DSIT's other IT and consulting activities which are included in Acorn's Other segment activities. The decrease in revenues at USSI was due to the timing of the delivery of USSI's sensor systems - in particular the delay in the delivery of a system to SR2020 on a $1.0 million project.
Gross profit.
Gross profit in the first half of 2013 reflected an increase of $711,000 (26%) as compared to the first half of 2012. DSIT's first half 2013 gross profit increased by $95,000 (4%) over first half 2012 gross profit. The increase in DSIT's gross profit was attributable to increased gross margins which improved from 37% in 2012 to 38% in 2013. DSIT's increased gross margins in 2013 were due to higher margin projects being worked on in 2013 as compared to 2012. GridSense's first half 2013 gross profit increased by $233,000 (29%) over first half 2012 gross profit. The increase in GridSense's gross profit was attributable to increased
33

revenues which offset a slight decrease in gross margins which fell to 42% in 2013 from 43% in 2013. USSI continued to show a negative gross profit in 2013 ($850,000) as it continues to incur increased engineering and production costs as it transitions from development of its products to production in its proof-of-concept projects. Approximately $280,000 of the negative gross profit was attributable to the write-off of inventory to cost of sales. OmniMetrix recorded gross profit of $601,000 (reflecting a 57% gross margin) in 2013 as compared to a negative $29,000 gross profit recorded in period since our acquisition of OmniMetrix in February 2012. The increased gross margin at OmniMetrix reflects the increasing levels monitoring of revenue recorded which are high margin revenues.
Research and development (“R&D”) expenses. R& D expenses increased $1.1 million from $3.0 million in the first half of 2012 to $4.1 million in the first half of 2013. The bulk of the increase in R&D expenses was at GridSense and DSIT whose R&D expense increased $0.7 million and $0.3 million, respectively, as compared to the first half of 2012. The increase at GridSense was due to the growth in GridSense's engineering team over the course of 2012 in order to accelerate the development of some key products. DSIT's increased R&D expense is related to work on the joint development (with USSI) of the PAUSS next generation integrated passive/active threat detection system for underwater site protection and efforts to expand DSIT's portfolio of products to include land-based security fiber-optic solutions. OmniMetrix also recorded an increase in R&D expense of $0.2 million each as compared to the first half of 2012 (OmniMetrix's R&D expense in 2012 was only for the period since our acquisition in February 2012) while USSI's R&D expense in the first half of 2013 was decreased slightly ($0.1 million) from $1.8 million to $1.7 million.
Selling, general and administrative (“SG&A”) expenses. SG&A costs in the first half of 2013 increased by $1.6 million as compared to the first half of 2012. The increased SG&A was attributable to increases recorded at OmniMetrix, DSIT and USSI while GridSense SG&A decreased in the first half of 2013 as compared to the first half of 2012 while corporate general and administrative costs were relatively unchanged. OmniMetrix recorded $2.4 million of SG&A in the current period as compared to $0.8 million for the period in 2012 following our acquisition. The increase in SG&A costs at OmniMetrix is due to the increased personnel costs (primarily in sales and marketing) and other costs associated with developing the necessary infrastructure for expected growth. DSIT's SG&A increased from $1.5 million in 2012 to $1.6 million in 2013. DSIT's increased SG&A was related to increased salary costs as well as increased marketing expenses. USSI's SG&A increased from $1.4 million in 2012 to $1.6 million in 2013. USSI's increased SG&A expense was attributable to increased salary expense as a result of added headcount and increased spending related to sales and marketing activities. In 2013, GridSense recorded a decrease of $0.3 million of SG&A expense to $1.8 million. GridSense's decreased SG&A expense was attributable to headcount reduction due to role consolidation and cost cutting measures that were commenced in late 2012 and continued into 2013.
Impairment of intangibles. During the second quarter of 2013, a customer with whom OmniMetrix had a significant on-going relationship at the time of Acorn's acquisition of OmniMetrix in February 2012 indicated that they would be disconnecting all of their monitoring units over a period of time. Following the decision to disconnect their monitoring units, OmniMetrix recorded an impairment of the intangible asset of approximately $1.1 million.
Restructuring and related charges. Following the change in the top-level management at GridSense, the company undertook a number of cost cutting measures in GridSense's U.S. and Australian operations. This action was taken primarily in order to improve efficiency based on GridSense's revenue mix and skills mix in order to position the company to meet its cash flow goals. As a result, during the second quarter, GridSense recorded a total restructuring charge in the second quarter of 2013 of $0.6 million.
Net loss attributable to Acorn Energy. We had a net loss attributable to Acorn Energy of $12.1 million in the first half of 2013 compared to a net loss of $7.4 million in the first half of 2012. Our loss in 2013 was primarily due to losses at USSI ($4.2 million), OmniMetrix ($3.1 million which includes the non-cash loss on the impairment of intangibles of $1.1 million noted above) and GridSense losses of $2.7 million (which includes the loss of $0.6 million on restructuring and related charges noted above) with corporate expenses contributing an additional $2.8 million. These losses were offset by DSIT's profit of approximately $0.2 million for the first half of 2013 and the non-controlling interest's share of our operations of approximately $0.5 million.

Liquidity and Capital Resources
As of June 30, 2013, we had working capital of $23.8 million. Our working capital includes $13.3 million of cash and cash equivalents and restricted deposits of approximately $0.6 million. Net cash decreased during the six months ended June 30, 2013 by $12.8 million, of which approximately $11.0 million was used in operating activities. The primary use of cash in operating activities during the first six months of 2013 was the cash used in operations by our subsidiaries ($4.8 million, $2.1 million, $1.5 million and $0.4 million used by USSI, GridSense, OmniMetrix and DSIT, respectively) in their operations combined with the $2.2 million of cash used in our corporate operating activities. Of USSI's $4.8 million of cash used in operations, $1.8 was used for the build-up of inventory.
Cash used in investment activities of $1.3 million was primarily due to the acquisition of property and equipment ($1.4 million). Such acquisitions of property and equipment were primarily at OmniMetrix related to leasehold improvements at its new facilities and at USSI for production equipment. The net cash released from restricted deposits ($0.2 million) were partially offset by the cash used to fund severance liabilities ($0.1 million).
Net cash of $0.4 million was used in financing activities, primarily from the payment of dividends during the first six months of 2013 ($0.5 million) which was partially offset by the net change in short and long-term debt ($0.1 million).
At June 30, 2013, DSIT had approximately $0.5 million of unrestricted cash in banks and NIS 4 million (approximately$1.1 million) in Israeli credit lines available to it from two Israeli banks (approximately $550,000 from each bank), none of which was then being used. The lines-of-credit are subject to maintaining certain financial covenants. At June 30, 2013, DSIT was in compliance with its financial covenants.
As at June 30, 2013, DSIT also had an outstanding term loan from an Israeli bank in the amount of approximately $75,000. The loan is denominated in NIS and bears interest at the rate of the Israeli prime rate per annum plus 0.9%. The loan is to be repaid in equal payments of approximately $12,500 per month (principal and interest) through December 2013.
In accordance with the terms of the loan, DSIT has deposited with an Israeli bank approximately $75,000 as a restricted deposit. In addition to this restricted deposit, DSIT has also deposited with two Israeli banks approximately $525,000 as collateral for various performance and bank guarantees for various projects as well as for its credit facilities at the banks. As restricted deposits are released, DSIT generally expects to redeposit these funds again as collateral for new guarantees for new projects and for renewing its credit facilities.
On July 31, 2013, DSIT had approximately $1.2 million of cash of which approximately $0.5 million was restricted (all current) and was not utilizing any of its lines-of-credit. In July, DSIT and Acorn entered into an agreement pursuant to which Acorn would convert a prior loan into additional ordinary (common) shares of DSIT. Acorn would also convert $2.8 million of loans and advances and make an aggregate further investment in DSIT of up to $2.2 million to purchase shares of DSIT Preferred Stock. Acorn invested $0.8 million of the $2.2 million in July. We believe that DSIT will have sufficient liquidity to finance its activities from cash flows from its own operations over the next 12 months based on its current cash balance, continued utilization of its lines-of-credit, the expected investment from Acorn and its operating results.
In August 2012, GridSense signed a Loan and Security Agreement with a bank to provide it with up to a $1.0 million revolving line of credit (subject to a calculated borrowing base). Advances from the line-of-credit bear interest at a variable annual interest rate equal to the greater of 3.25% above the Prime Rate in effect (3.25% at June 30, 2013) or 6.5%. The line-of-credit is also subject to certain financial covenants. GridSense was not in compliance with its financial covenants at June 30, 2013 due to the effect of the restructuring. GridSense has received a covenant waiver from its bank. As of July 31, 2013, GridSense was utilizing $155,000 of this line-of-credit.
In 2013, we committed to fund an additional $1.5 million to GridSense (the "GridSense Commitment") plus an additional $480,000 to fund the cost of the restructuring, all of which has already been funded in 2013. Following the restructuring of activities at GridSense, we believe that with a reduced cost structure and improving sales, GridSense will be significantly less reliant on us for working capital support. We have no assurance that GridSense will meet its goal of being cash flow neutral in the second half of 2013 or increase its sales and reduce its need for additional financing to support its working capital needs. Additional working capital support may be in the form of an additional or expanded bank line, new investment by others, additional investment or loans by Acorn, or a combination of the above. There is no assurance that GridSense will be able to obtain an additional or expanded line-of-credit or other support in sufficient amounts, in a timely manner or on acceptable terms. The availability and amount of any additional investment from us in GridSense may be limited by the working capital needs of our corporate activities and other operating companies. On July 31, 2013, GridSense had cash on hand of approximately $0.1 million.
OmniMetrix currently has no other sources of financing other than its internally generated sales and investments by Acorn. On February 26, 2013, we committed to fund an additional $3.0 million to OmniMetrix (the "OmniMetrix Commitment"),
35

Table of Contents
of which $2.00 million has been funded through July 31, 2013. The OmniMetrix Commitment will be funded in increments as we deem necessary during the balance of 2013.
As of July 31, 2013, OmniMetrix had cash on hand of approximately $0.1 million. OmniMetrix has begun discussions with a bank to provide working capital financing; however, there is no assurance that such financing from the bank or any other party will be available in sufficient amounts, in a timely manner or on acceptable terms. We have no assurance that OmniMetrix will not need additional financing for working capital after we complete our $3.0 million investment under the OmniMetrix Commitment. Additional financing for OmniMetrix may be in the form of a bank line, new investment by others, a loan or investment by Acorn, or a combination of the above. There is no assurance that such support will be available from such sources in sufficient amounts, in a timely manner or on acceptable terms. The availability and amount of any additional investment from us in OmniMetrix may be limited by the working capital needs of our corporate activities and other operating companies.
In November 2012, USSI signed a Loan and Security Agreement with a bank to provide it with up to a $1.0 million non-formula revolving line of credit. The Loan and Security Agreement expires on November 7, 2013. USSI has begun discussions with the bank to expand this line of credit. Advances from the line-of-credit bear interest at a variable annual interest rate equal to the greater of 1.0% above the Prime Rate in effect or 6.5%. The line-of-credit is also subject to certain financial covenants. At June 30, 2013, USSI was in compliance with its financial covenants. As of July 31, 2013, USSI was not utilizing any of this line-of-credit.
We have no assurance that USSI will not need additional financing from time-to-time to finance its working capital needs as it continues to work on transitioning from development to production and as it continues to work on refining its manufacturing capabilities. USSI's sources of financing are its internally generated sales, investments by Acorn and its non-formula revolving line of credit. Acorn continues to provide funds for USSI's working capital needs and expects to do so in the future. On February 26, 2013, we agreed to purchase an additional $5.0 million of USSI Preferred Stock in accordance with the 2013 USSI Purchase Agreement, all of which has been funded.
As of July 31, 2013, USSI had cash on hand of approximately $0.25 million. Additional financing for USSI may be in the form of an additional or expanded bank line, new investment by others, a loan or investment by Acorn, or a combination of the above. While USSI's cash needs cannot be determined at this time, we anticipate the need to make on-going investments in order to support USSI's operations through the end of 2013. The availability and amount of any additional investment from us in USSI may be limited by the working capital needs of our corporate activities and the financing requirements of our other operating companies.
As of July 31, 2013, the Company's corporate operations (not including cash at any of our subsidiaries) had a total of approximately $9.7 million in cash and cash equivalents ($6.0 million in U.S. banks and $3.7 million in Israeli banks (all of which can be repatriated without any tax consequence)) representing a decrease of $1.6 million from our balance as of June 30, 2013. During the month of July we invested $800,000 in DSIT, $213,000 in GridSense, $250,000 in OmniMetrix. The balance of the decrease was for corporate expenses. Acorn anticipates receipt of its Federal income tax refund of approximately $1.7 million during the fourth quarter of 2013.
We believe that our current cash plus the cash expected to be generated from operations and borrowing from available lines of credit, if necessary, will provide sufficient liquidity to finance the operating activities of Acorn and the operations of its operating subsidiaries for at least the next 12 months. In order to position ourselves to take advantage of potential market expansion or complementary acquisitions for our existing businesses, we are contemplating whether and on what terms we may offer additional securities for sale in the future. We currently expect that we may conduct such an offering prior to the end of 2013, the amount and terms of which cannot be determined at this time.

We expect to finance these contractual commitments from cash currently on hand and cash generated from operations.
(1) Under Israeli law and labor agreements, DSIT is required to make severance payments to dismissed employees and to employees leaving employment under certain other circumstances. The obligation for severance pay benefits, as determined by the Israeli Severance Pay Law, is based upon length of service and last salary. These obligations are substantially covered by regular deposits with recognized severance pay and pension funds and by the purchase of insurance policies. As of June 30, 2013, we accrued a total of $4.8 million for potential severance obligations to our Israeli employees of which approximately $3.4 million was funded.
(2) In April 2012, USSI and Northrop Grumman signed a license agreement involving several of Northrop Grumman’s fiber-optic technology patents. The license agreement is subject to an annual minimum royalty payment of 10% of the net selling price of each unit of licensed products used or sold during the term of the agreement. The agreement also calls for a minimum annual payment of $50,000 for the first ten years of the agreement beginning in 2012. The table above includes as a royalty payment only the minimum payment due.
(3) Two of the employees of GridSense are entitled to a combined royalty of 6% of the sales of a particular product in excess of cumulative product sales of $4.0 million provided that the product remained substantially the same from the original date of the royalty agreement. The above table does not include any royalties that may be paid under this arrangement.
(4) OmniMetrix has an agreement with a third party equipment assembler, pursuant to which it commits to purchase a specified amount of product based upon its submitted forecasted needs. The table reflects the amount outstanding under an open purchase order.

ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Foreign Currency Risk
Our non-US dollar monetary assets and liabilities (net assets of less than $0.1 million) in Israel at our DSIT subsidiary are exposed to fluctuations in exchange rates. In addition, our non-US dollar monetary assets and liabilities (net liability of approximately $0.4 million) in Australia at our GridSense subsidiary are also exposed to fluctuations in exchange rates. Our DSIT subsidiary enters into various hedging contracts which do not qualify as hedging instruments under accounting principles to try to mitigate its foreign currency exposure risks. GridSense does not employ specific strategies, such as the use of derivative instruments or hedging, to manage its foreign currency exchange rate exposures.
Concentrations of Credit Risk
Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash and cash equivalents, restricted deposits, trade receivables and unbilled revenue. The counterparty to a significant portion of our cash and cash equivalents ($5.4 million) is in money markets of two major financial institutions while an additional $1.1 million is in a checking account at one of those major financial institutions. We do not believe there is significant risk of non-performance by these counterparties. The counterparty to our restricted deposits ($0.6 million) and approximately $6.5 million of our cash and equivalents are two major Israeli banks. We do not believe there is significant risk of non-performance by these counterparties. Approximately 33% ($1.1 million) of the trade accounts receivable at June 30, 2013 was due from two customers that pay over usual credit periods. Credit risk with respect to the balance of trade receivables is generally diversified due to the number of entities comprising our customer base. Approximately 67% of the balance in unbilled revenue at June 30, 2013 was due from three customers that have historically paid their trade receivables over usual credit periods. Credit risk with respect to the balance of unbilled revenue is generally diversified due to the number of entities comprising our customer base.
Fair Value of Financial Instruments
Fair values of financial instruments included in current assets and current liabilities are estimated to approximate their book values due to the short maturity of such investments. Fair value for long-term debt and long-term deposits are estimated based on the current rates offered to us for debt and deposits with similar terms and remaining maturities. The fair value of our long-term debt and non-current restricted deposits are not materially different from their book values.
Interest Rate Risk
In the normal course of business, we are exposed to fluctuations in interest rates on our lines-of-credit ($1.1 million available) and term loan ($0.1 million balance at June 30, 2013) to finance our operations in Israel. Such lines-of-credit and loan bear interest at interest rates that are linked to the Israeli prime rate (2.75% at June 30, 2013).
In addition, both GridSense and USSI have lines-of-credit ($1.0 million each) which bear interest at interest rates which are linked to the Prime Rate in effect (3.25% at June 30, 2013).
