Notes to Interim Unaudited Condensed Consolidated Financial Statements for the Nine Months Ended September 30, 2013

Note 1 – Description of business and summary of significant accounting policies

Description of business

Tecogen Inc. (the “Company”) (a Delaware Corporation) was organized on November 15, 2000, and acquired the assets and liabilities of the Tecogen Products division of Thermo Power Corporation. The Company produces commercial and industrial, natural-gas-fueled engine-driven, combined heat and power (CHP) products that reduce energy costs, decrease greenhouse gas emissions and alleviate congestion on the national power grid. The Company’s products supply electric power or mechanical power for cooling, while heat from the engine is recovered and purposefully used at a facility. The majority of the Company’s customers are located in regions with the highest utility rates, typically California, the Midwest and the Northeast.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and therefore do not include all information and notes necessary for a complete presentation of our financial position, results of operations and cash flows, in conformity with generally accepted accounting principles. We filed audited financial statements which included all information and notes necessary for such presentation for the two years ended December 31, 2012 in conjunction with our 2012 Annual Report on Form 10-K, or our Annual Report, filed with the Securities and Exchange Commission, or SEC, on March 27, 2013. This form 10-Q should be read in conjunction with that Form 10-K.

The accompanying unaudited consolidated balance sheets, statements of operations and statements of cash flows reflect all adjustments (consisting only of normal recurring items) which are, in the opinion of management, necessary for a fair presentation of financial position at September 30, 2013, and of operations and cash flows for the interim periods ended September 30, 2013 and 2012. The results of operations for the interim periods ended September 30, 2013 are not necessarily indicative of the results to be expected for the year.

The accompanying consolidated financial statements include the accounts of the Company and its 65.0% owned subsidiary Ilios, whose business focus is on advanced heating systems for commercial and industrial applications. With the inclusion of unvested restricted stock awards, the Company's owns 63.7% of Ilios.

The Company’s operations are comprised of one business segment. Our business is to manufacture and support highly efficient CHP products based on engines fueled by natural gas.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable and collectability is reasonably assured. Generally, sales of cogeneration and chiller units and parts are recognized when shipped and services are recognized over the term of the service period. Payments received in advance of services being performed are recorded as deferred revenue.

Infrequently, the Company recognizes revenue in certain circumstances before delivery has occurred (commonly referred to as bill and hold transactions). In such circumstances, among other things, risk of ownership has passed to the buyer, the buyer has made a written fixed commitment to purchase the finished goods, the buyer has requested the finished goods be held for future delivery as scheduled and designated by them, and no additional performance obligations exist by the Company. For these transactions, the finished goods are segregated from inventory and normal billing and credit terms are granted. For the nine months ended September 30, 2013 and 2012 no revenues were recorded as bill and hold transactions.

TECOGEN INC.

For those arrangements that include multiple deliverables, the Company first determines whether each service or deliverable meets the separation criteria of FASB ASC 605-25, Revenue Recognition—Multiple-Element Arrangements. In general, a deliverable (or a group of deliverables) meets the separation criteria if the deliverable has stand-alone value to the customer and if the arrangement includes a general right of return related to the delivered item and delivery or performance of the undelivered item(s) is considered probable and substantially in control of the Company. Each deliverable that meets the separation criteria is considered a separate ‘‘unit of accounting”. The Company allocates the total arrangement consideration to each unit of accounting using the relative fair value method. The amount of arrangement consideration that is allocated to a delivered unit of accounting is limited to the amount that is not contingent upon the delivery of another unit of accounting.

When vendor-specific objective evidence or third-party evidence is not available, adopting the relative fair value method of allocation permits the Company to recognize revenue on specific elements as completed based on the estimated selling price. The Company generally uses internal pricing lists that determine sales prices to external customers in determining its best estimate of the selling price of the various deliverables in multiple-element arrangements. Changes in judgments made in estimating the selling price of the various deliverables could significantly affect the timing or amount of revenue recognition. The Company enters into sales arrangements with customers to sell its cogeneration and chiller units and related service contracts and occasionally installation services. Based on the fact that the Company sells each deliverable to other customers on a stand-alone basis, the company has determined that each deliverable has a stand-alone value. Additionally, there are no rights of return relative to the delivered items; therefore, each deliverable is considered a separate unit of accounting.

After the arrangement consideration has been allocated to each unit of accounting, the Company applies the appropriate revenue recognition method for each unit of accounting based on the nature of the arrangement and the services included in each unit of accounting. Cogeneration and chiller units are recognized when shipped and services are recognized over the term of the applicable agreement, or as provided when on a time and materials basis.

In some cases, our customers may choose to have the Company engineer and install the system for them rather than simply purchase the cogeneration and/or chiller units. In this case, the Company accounts for revenue, or turnkey revenue, and costs using the percentage-of-completion method of accounting. Under the percentage-of-completion method of accounting, revenues are recognized by applying percentages of completion to the total estimated revenues for the respective contracts. Costs are recognized as incurred. The percentages of completion are determined by relating the actual cost of work performed to date to the current estimated total cost at completion of the respective contracts. When the estimate on a contract indicates a loss, the Company’s policy is to record the entire expected loss, regardless of the percentage of completion. During the nine months ended September 30, 2013 a loss of approximately $300,000 was recorded. The excess of contract costs and profit recognized to date on the percentage-of-completion accounting method in excess of billings is recorded as unbilled revenue. Billings in excess of related costs and estimated earnings is recorded as deferred revenue.

Presentation of Sales Taxes

The Company reports revenues net of any revenue-based taxes assessed by governmental authorities that are imposed on and concurrent with specific revenue-producing transactions.

Shipping and Handling Costs

The Company classifies freight billed to customers as sales revenue and the related freight costs as cost of sales.

Advertising Costs

The Company expenses the costs of advertising as incurred. For the nine months ended September 30, 2013 and 2012, advertising expense was approximately $147,000 and $133,000, respectively.

Cash and Cash Equivalents

The Company considers all highly liquid instruments with an original maturity date, at date of purchase, of three months or less to be cash and cash equivalents. The Company has cash balances in certain financial institutions in amounts which occasionally exceed current federal deposit insurance limits. The financial stability of these institutions is continually reviewed by senior management. The Company believes it is not exposed to any significant credit risk on cash and cash equivalents.

TECOGEN INC.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments and accounts receivable. The Company's cash equivalents are placed with certain financial institutions and issuers. As of September 30, 2013, the Company had a balance of $144,091 in cash and cash equivalents and short-term investments that exceeded the Federal Deposit Insurance Corporation’s (“FDIC”) general deposit insurance limit of $250,000.

Short-Term Investments

Short-term investments consist of certificates of deposit with maturities of greater than three months but less than one year. Certificates of deposits are recorded at fair value.

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for doubtful accounts is provided for those accounts receivable considered to be uncollectible based upon historical experience and management’s evaluation of outstanding accounts receivable at the end of the year. Bad debts are written off against the allowance when identified. At September 30, 2013 and December 31, 2012 the allowance for doubtful accounts was $119,700 and $154,400, respectively.

Inventory

Raw materials, work in process, and finished goods inventories are stated at the lower of cost, as determined by the average cost method, or net realizable value. The Company periodically reviews inventory quantities on hand for excess and/or obsolete inventory based primarily on historical usage, as well as based on estimated forecast of product demand. Any reserves that result from this review are charged to cost of sales.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation is provided using the straight-line method over the estimated useful lives of the asset, which range from three to fifteen years. Leasehold improvements are amortized using the straight-line method over the lesser of the estimated useful lives of the assets or the term of the related leases. Expenditures for maintenance and repairs are expensed currently, while renewals and betterments that materially extend the life of an asset are capitalized.

Intangible Assets

Intangible assets subject to amortization include costs incurred by the Company to acquire developed technology discussed in Note 10, product certifications and certain patent costs. These costs are amortized on a straight-line basis over the estimated economic life of the intangible asset. The Company reviews intangible assets for impairment when the circumstances warrant.

Goodwill

The Company's goodwill was recorded as a result of the Company's asset acquisition discussed in Note 9. The Company has recorded this transaction using the acquisition method of accounting. The Company tests its recorded goodwill for impairment on an annual basis, or more often if indicators of potential impairment exist, by determining if the carrying value of the Company's single reporting unit exceeds its estimated fair value. Factors that could trigger an interim impairment test include, but are not limited to, underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the Company's overall business, significant negative industry or economic trends and a sustained period where market capitalization, plus an appropriate control premium, is less than stockholders' equity. During the first nine months of 2013 the Company determined that no interim impairment test was necessary. Goodwill will be assessed for impairment at least annually or when there are indicators of potential impairment.

TECOGEN INC.

Common Stock

The Company's common stock was split one-for-four in a reverse stock split effective July 22, 2013. The effect of this reverse stock split has been retroactively applied to per share data and common stock information.

Impairment of long-lived assets

Long-lived assets are evaluated for impairment whenever events or changes in circumstances have indicated that an asset may not be recoverable and are grouped with other assets to the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. If the sum of the projected undiscounted cash flows (excluding interest charges) is less than the carrying value of the assets, the assets will be written down to the estimated fair value and such loss is recognized in income from continuing operations in the period in which the determination is made. Management determined that no impairment of long-lived assets existed as of September 30, 2013.

Off Balance Sheet Arrangements

On July 22, 2013, the Company’s Chief Executive Officer personally pledged to support a bank credit facility of $1,055,000 to support bank guarantees issued on certain construction contracts.

Research and Development Costs/Grants

Internal research and development expenditures are expensed as incurred. Proceeds from certain grants and contracts with governmental agencies and their contractors to conduct research and development for new CHP technologies or to improve or enhance existing technology is recorded as an offset to the related research and development expenses. These grants and contracts are paid on a cost reimbursement basis provided in the agreed upon budget, with 10% retainage held to the end of the contract period. For the nine months ended September 30, 2013 and 2012, amounts received were approximately $115,150 and $101,400, respectively, which offset the Company’s total research and development expenditures for each of the respective periods. As of September 30, 2013 and December 31, 2012, retainage receivable was approximately $138,350 and $154,700, respectively.

Stock-Based Compensation

Stock based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as an expense in the consolidated statements of operations over the requisite service period. The fair value of stock options granted is estimated using the Black-Scholes option pricing valuation model. The Company recognizes compensation on a straight-line basis for each separately vesting portion of the option award. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. The determination of the fair value of share-based payment awards is affected by the Company’s stock price. Since the Company is not actively traded, the Company considered the sales price of the Common Stock in private placements to unrelated third parties as a measure of the fair value of its Common Stock. The average expected life is estimated using the simplified method for “plain vanilla” options. The simplified method determines the expected life in years based on the vesting period and contractual terms as set forth when the award is made. The Company uses the simplified method for awards of stock-based compensation since it does not have the necessary historical exercise and forfeiture data to determine an expected life for stock options. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term which approximates the expected life assumed at the date of grant. When options are exercised the Company normally issues new shares (see “Note 4 – Stock-based compensation”.)

Loss per Common Share

The Company computes basic loss per share by dividing net loss for the period by the weighted-average number of shares of Common Stock outstanding during the period. The Company computes its diluted earnings per common share using the treasury stock method. For purposes of calculating diluted earnings per share, the Company considers its shares issuable in connection with the convertible debentures, stock options and warrants to be dilutive Common Stock equivalents when the exercise/conversion price is less than the average market price of our Common Stock for the period.

Other Comprehensive Net Loss

The comprehensive net loss for the three and nine month periods ended September 30, 2013 and 2012 does not differ from the reported loss.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. The current or deferred tax consequences of transactions are measured by applying the provisions of enacted tax laws to determine the amount of taxes payable currently or in future years. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities and expected future tax consequences of events that have been included in the financial statements or tax returns using enacted tax rates in effect for the years in which the differences are expected to reverse. Under this method, a valuation allowance is used to offset deferred taxes if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets may not be realized. Management evaluates the recoverability of deferred taxes and the adequacy of the valuation allowance annually.

The Company follows the provisions of the accounting standards relative to accounting for uncertainties in tax positions. These provisions provide guidance on the recognition, de-recognition and measurement of potential tax benefits associated with tax positions. The Company elected to recognize interest and penalties related to income tax matters as a component of income tax expense in the statements of operations. There was no impact on the financial statements as a result of this guidance.

The Company’s headquarters are located in Waltham, Massachusetts and consist of 27,000 square feet of office and storage space that are shared with American DG Energy and other tenants. The lease expires on March 31, 2024. We believe that our facilities are appropriate and adequate for our current needs.

Revenue from sales of cogeneration and chiller systems, parts and service to American DG Energy during the nine months ended September 30, 2013 and 2012 amounted to $546,279 and $1,596,420, respectively. In addition, Tecogen pays certain operating expenses, including benefits and insurance, on behalf of American DG Energy. Tecogen was reimbursed for these costs. As of September 30, 2013 the total amount due to American DG Energy was $396,328, which is included in due to related party on the accompanying condensed consolidated balance sheet.

Note 8 – Fair value measurements

The fair value topic of the FASB Accounting Standards Codification defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The accounting guidance also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities. We currently do not have any Level 1 financial assets or liabilities.

Level 2 - Observable inputs other than quoted prices included in Level 1. Level 2 inputs include quoted prices for identical assets or liabilities in non-active markets, quoted prices for similar assets or liabilities in active markets and inputs other than quoted prices that are observable for substantially the full-term of the asset or liability.

Level 3 - Unobservable inputs reflecting management’s own assumptions about the input used in pricing the asset or liability. We currently do not have any Level 3 financial assets or liabilities.

TECOGEN INC.

The Company’s financial instruments that are not recorded at fair value on a recurring basis include cash and cash equivalents, accounts receivable, accounts payable, capital lease obligations, related party demand notes payable and related party convertible debentures. The recorded values of cash and cash equivalents, accounts receivable and accounts payable approximate their fair values based on their short-term nature. At September 30, 2013, the carrying value on the consolidated balance sheet of the notes payable, convertible debentures and capital lease obligations approximates fair value based on current market rates for instruments with similar maturities adjusted for applicable credit risk, which are Level 2 inputs.

Note 9 - Asset acquisition

On January 9, 2013 the Company purchased certain assets, both tangible and intangible, required to manufacture the generator used in its InVerde product from Danotek Motion Technologies. The aggregate consideration paid by the Company was $497,800, of which $17,400 represents the fair value of inventory and $199,530 represents the estimated fair value of property, plant and equipment which is depreciated over useful lives ranging from 5 to 8.5 years. The fair value of the property, plant and equipment was estimated utilizing a replacement cost method. In addition, $240,000 of the purchase consideration represents the fair value of identified intangible assets using a relief from royalty method with a useful life of fifteen years. The balance of $40,870 is included in goodwill in the accompanying condensed consolidated balance sheet, which consists largely of economies of scale expected from combining the manufacturing of the generator into Tecogen's operations. Acquisition related costs were not material to the financial statements and were expensed as incurred to general and administrative expenses.

This transaction was accounted for under the purchase method of accounting in accordance with FASB ASC Topic 805, Business Combinations. Under the purchase method of accounting, the total purchase price has been allocated to the net tangible and intangible assets acquired based on estimates of their values by the Company's management. There is one reporting unit within the Company.

Under the purchase method of accounting, an acquisition is recorded as of the closing date, reflecting the purchased assets, at their acquisition date fair values.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

Forward-looking statements are made throughout this Management’s Discussion and Analysis of Financial Condition and Results of Operations. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words “believes,” “anticipates,” “plans,” “expects,” “seeks,” “estimates” and similar expressions are intended to identify forward-looking statements. Such forward-looking statements include, among other things, statements regarding our current and future cash requirements, our expectations regarding suppliers of cogeneration units, and statements regarding potential financing activities in the future. While the Company may elect to update forward-looking statements in the future, it specifically disclaims any obligation to do so, even if the Company’s estimates change and readers should not rely on those forward-looking statements as representing the Company’s views as of any date subsequent to the date of the filing of this Quarterly Report. There are a number of important factors that could cause the actual results of the Company to differ materially from those indicated by such forward-looking statements, including those detailed under the heading “Risk Factors” in this Quarterly Report.

Overview

Tecogen designs, manufactures and sells industrial and commercial cogeneration systems that produce combinations of electricity, hot water, and air conditioning using automotive engines that have been specially adapted to run on natural gas. In some cases, our customers may choose to have the Company engineer and install the system for them rather than simply purchase the cogeneration and/or chiller units, which we refer to as "turnkey" projects. Cogeneration systems are efficient because in addition to supplying mechanical energy to power electric generators or compressors – displacing utility supplied electricity – they provide opportunity for the facility to incorporate the engine’s waste heat into onsite processes such as space and potable water heating. We produce standardized, modular, small-scale products, with a limited number of product configurations that are adaptable to multiple applications. We refer to these combined heat and power products as CHP (electricity plus heat) and MCHP (mechanical power plus heat).

Results of Operations

Third quarter of 2013 Compared to Third quarter of 2012

Revenues

Revenues in the third quarter of 2013 were $2,893,240 compared to $3,052,556 in for the same period in 2012, a decrease of $159,316 or 5.2%. This decrease is due to a decrease in the volume of product shipments during the period. Product revenues in the third quarter of 2013 were $779,455 compared to $1,354,013 for the same period in 2012, a decrease of $574,558 or 42.4%. This decrease from the three months ended September 30, 2012 to September 30, 2013 was the aggregate of a decrease in cogeneration sales of $363,915 and a decrease in chiller sales of $210,643. Our product mix, as well as product revenue, can vary significantly from period to period as our products are high dollar, low volume sales. As a result, such fluctuation is expected.

Service revenues in the third quarter of 2013 were $2,113,785 compared to $1,698,543 for the same period in 2012, an increase of $415,242 or 24.4%. Our service operation grows along with sales of cogeneration and chiller systems since the majority of our product sales are accompanied by a service contract or time and materials agreement. As a result our “fleet” of units being serviced by our service department naturally grows with product sales.

Cost of Sales

Cost of sales in the third quarter of 2013 was $1,800,608 compared to $1,868,132 for the same period in 2012 a decrease of $67,524, or 3.6%. During the third quarter of 2013 our overall gross profit margin was 37.8% compared to 38.8% for the same period in 2012, a slight decrease of 1.0%.

Contract Research and Development

Contract research and development income, which is classified as an offset to applicable expenses, for the three months ended September 30, 2013 and September 30, 2012 was $9,094 and $19,892, respectively, a decrease of $10,798.

Operating Expenses

Our general and administrative expenses consist of executive staff, accounting and legal expenses, office space, general insurance and other administrative expenses. Our general and administrative expenses in the third quarter of September 30, 2013 were $1,697,330 compared to $1,493,652 for the same period in 2012, an increase of $203,678 or 13.6%. This increase was due to an overall increase in operating costs attributable to an increase in internal research and development activities of $83,100 as well as the costs associated with being a newly public company and financing activities.

Our selling expenses consist of sales staff, commissions, marketing, travel and other selling related expenses. Our selling expenses for the third quarter of 2013 were $488,895 compared to $450,305 for the same period in 2012, an increase of $38,590 or 8.6%. This increase is due to the increase in costs associated with trade shows, commissions and royalties during the third quarter of 2013 as compared to the same period in 2012.

In addition, the initial public offering activities, which took place during the third quarter of 2013, was aborted and therefore cost associated with this offering of $320,924 were charged to expense rather than against equity as no equity was raised.

Loss from Operations

Loss from operations for the third quarter of 2013 was $1,414,517 compared to $759,533 for the same period in 2012. The increase in the loss of $654,984 was due to the decrease in revenue and increase in operating expenses discussed above.

Other Income (Expense), net

Other expense, net for the three months ended September 30, 2013 was $37,816 compared to $7,588 for the same period in 2012. Other income (expense) includes interest income and other income of $7,256, net of interest expense on notes payable of $45,072 for the third quarter of 2013. For the same period in 2012, interest and other income was $10,214 and interest expense was $17,802. The decrease in interest income of $2,958 is the result of short-term investments held during the third quarter of 2012 that were not held during the third quarter of 2013. The increase in interest expense of $27,270 was mainly due to the increase in demand notes payable issued during the fourth quarter of 2012 and later.

Provision for Income Taxes

The Company did not record any benefit or provision for income taxes for the three months ended September 30, 2013 and 2012, respectively. As of September 30, 2013 and 2012, the income tax benefits generated from the Company’s net losses have been fully reserved.

Noncontrolling Interest

The noncontrolling interest share in the losses of Ilios was $64,654 for the three months ended September 30, 2013 compared to $92,516 for the same period in 2012, a decrease of $27,862 or 30.1%. The decrease was due to a decrease in the noncontrolling interest ownership as well as a decrease in the Ilios loss in the third quarter of 2013 as compared to the same period in 2012. Noncontrolling interest ownership percentage as of September 30, 2013 and 2012 was 35.0% and 37.6%, respectively. Shares of restricted common stock issued under Ilios's equity compensation plan, but which have not yet vested, have not been included in calculating the noncontrolling interest ownership percentage.

First nine months of 2013 Compared to First nine months of 2012

Revenues

Revenues in the first nine months of 2013 were 9,743,018 compared to 9,689,984 in for the same period in 2012, an increase of $53,034 or 0.5%. Product revenues in the first nine months of 2013 were $3,639,974 compared to $4,191,439 for the same period in 2012, a decrease of $551,465 or 13.2%. This decrease from the nine months ended September 30, 2012 to September 30, 2013 was due to a decrease in both cogeneration and chiller shipments sales of $246,029 and $305,436, respectively. Our product mix, as well as product revenue, can vary significantly from period to period as our products are high dollar, low volume sales in which revenue is only recognized upon shipment. As a result, such fluctuation is expected.

TECOGEN INC.

Service revenues in the first nine months of 2013 were $6,103,044 compared to $5,498,545 for the same period in 2012, an increase of $604,499 or 11.0%. This increase was due to an increase in service contracts and time and materials activities that accompanied products sold by us in prior periods.

Cost of Sales

Cost of sales in the first nine months of 2013 was $6,724,549 compared to $5,703,507 for the same period in 2012 a increase of $1,021,042, or 17.9%. During the first nine months of 2013 our overall gross profit margin was 31.0% compared to 41.1% for the same period in 2012, a decrease of 10.1%. The decrease in overall gross margin is attributable to the recognition of an anticipated future loss of approximately $300,000 on a turnkey project in process as well as the sale of certain Ilios promotional units at below cost.

Contract Research and Development

Contract research and development income, which is classified as an offset to applicable expenses, for the nine months ended September 30, 2013 and September 30, 2012 was $115,150 and $101,400, respectively, an increase of $13,750.

Operating Expenses

Our general and administrative expenses consist of executive staff, accounting and legal expenses, office space, general insurance and other administrative expenses. Our general and administrative expenses in the first nine months of 2013 were $5,168,315 compared to $4,851,398 for the same period in 2012, an increase of $316,917 or 6.5%. This increase was due to internal research and development costs incurred of $283,425 as well as an overall increase in operating costs attributable to being a newly public company and financing activities.

Our selling expenses consist of sales staff, commissions, marketing, travel and other selling related expenses. Our selling expenses for the first nine months of 2013 was $1,054,366 compared to $915,842 for the same period in 2012, an increase of $138,524 or 15.1%. This increase is due to the increase in costs associated with trade shows, commissions and royalties during the first nine months of 2013 as compared to the same period in 2012.

In addition, costs associated with our abandoned public offering during the third quarter of 2013 in the amount of $320,924 were charged to expense rather than against equity, as no equity was raised.

Loss from Operations

Loss from operations for the first nine months of 2013 was $3,525,136 compared to $1,780,763 for the same period in 2012. The increase in the loss of $1,744,373 was due to the increase in cost of sales and operating expenses discussed above.

Other Income (Expense), net

Other expense, net for the nine months ended September 30, 2013 was $91,043 compared to $15,026 for the same period in 2012. Other income (expense) includes interest income and other income of $13,793, net of interest expense on notes payable of $104,836 for the first quarter of 2013. For the same period in 2012, interest and other income was $38,380 and interest expense was $53,406. The decrease in interest income of $24,587 is the result of short-term investments held during the first nine months of 2012 that were not held during the first nine months of 2013. The increase in interest expense of $51,430 was mainly due to demand notes payable issued during the fourth quarter of 2012 and the third quarter of 2013.

Provision for Income Taxes

The Company did not record any benefit or provision for income taxes for the nine months ended September 30, 2013 and 2012, respectively. As of September 30, 2013 and 2012, the income tax benefits generated from the Company’s net losses have been fully reserved.

Noncontrolling Interest

The noncontrolling interest share in the losses of Ilios was $277,627 for the nine months ended September 30, 2013 compared to $285,898 for the same period in 2012, a decrease of $8,271 or 2.9%. The decrease was due to a decrease in the noncontrolling interest ownership in the first nine months of 2013 as compared to the same period in 2012. Noncontrolling interest ownership percentage as of September 30, 2013 and 2012 was 35.0% and 37.6%, respectively. Shares of restricted common stock issued under Ilios's equity compensation plan, but which have not yet vested, have not been included in calculating the noncontrolling interest ownership percentage.

Liquidity and Capital Resources

Consolidated working capital at September 30, 2013 was $(322,458), compared to $4,078,704 at December 31, 2012, a decrease of $4,401,162. Included in working capital were cash and cash equivalents of $492,734 at September 30, 2013, compared to $1,572,785 in cash and cash equivalents and $181,859 in short-term investments at December 31, 2012. The decrease in working capital is due to increased operating expenses, increases in inventory, property and equipment, intangible assets, inventory and unbilled revenue from turnkey projects as well as the lack of any financing activities during the period.

Cash used in operating activities for the nine months ended September 30, 2013 was $1,467,276 compared to $3,554,463 for the same period in 2012. Our accounts receivable balance decreased to $2,301,012 at September 30, 2013 compared to $2,700,243 at December 31, 2012, using $399,231 of cash due to timing of billing, shipments and collections. Unbilled revenue increased by $140,081 as of September 30, 2013 compared to December 31, 2012, using $140,081 of cash due to timing of billing on our turnkey projects. Our inventory increased to $4,335,207 as of September 30, 2013 compared to $3,356,622 as of December 31, 2012, using $978,585 of cash to purchase inventory to build modules in backlog.

As of November 4, 2013, the Company's backlog of product and installation projects (and excluding service contracts) was $10.5 million, consisting of $6.5 million of purchase orders actually received by us and $4 million of projects in which the customer's internal approval process is complete, financial resources have been allocated and the customer has made a firm verbal commitment that the order is in the process of execution. We expect approximately 47% of this backlog will be recognized as revenue in the final quarter of 2013. Revenue expected to be recognized in a future period is comprised of a portion of the beginning backlog and expected new product sales. Backlog at the beginning of any period is not necessarily indicative of future performance. Our presentation of backlog may differ from other companies in our industry. Our inventory balances have increased to support production demands, tightening available working capital. As discussed below, we have drawn upon our working capital line of credit in the third quarter of 2013 to support this activity as needed.

Accounts payable increased to $2,897,641 as of September 30, 2013 from $1,151,010 at December 31, 2012, providing $1,746,631 in cash to purchase inventory. Accrued expenses increased to $1,091,277 as of September 30, 2013 from $807,922 as of December 31, 2012, providing $283,355 of cash for operations.

During the first nine months of 2013 our investing activities used $812,425 of cash and included purchases of property and equipment of $163,824 and expenditures related to intangible assets of $332,862 and an asset acquisition of $497,800.

At September 30, 2013 our commitments included various leases for office and warehouse facilities of $5,482,496 to be paid over several years through 2024. The source of funds to fulfill these commitments will be provided from cash balances, operations or through debt or equity financing.

On March 14, 2013 the Company received a prepayment for purchases of modules, parts and service to be made by American DG Energy in the amount of $827,747. The Company provides a discount on these prepaid purchases equal to 6% per annum on deposit balances. The 6% discount is recorded as interest expense in the accompanying statements of operations. As of September 30, 2013 the outstanding balance on this prepayment was $420,317 and is included in due to related party, net of amounts receivable but not yet due from American DG Energy, in the accompanying condensed consolidated balance sheet.

On March 25, 2013, the Company entered into a Revolving Line of Credit Agreement, or the Credit Agreement, with John N. Hatsopoulos, our Chief Executive Officer. Under the terms of the Credit Agreement, Mr. Hatsopoulos has agreed to lend the Company up to an aggregate of $1,000,000, from time to time, at the written request of the Company. Any amounts borrowed by the Company pursuant to the Credit Agreement will bear interest at the Bank Prime Rate as quoted from time to time in the Wall Street Journal plus 1.5% per year. On August 13, 2013, the Company and Mr. Hatsopoulos agreed to increase the amount that may be outstanding under the Credit Agreement to $1,500,000. Repayment of the principal amount borrowed, together with accrued interest, pursuant to the Credit Agreement will be due on March 31, 2014. Prepayment of any amounts due under the Credit Agreement may be made at any time without penalty, provided that prepayment of interest may not be

made prior to January 1, 2014. The Credit Agreement terminates on the March 31, 2014. As of November 14, 2013 the Company has borrowed $1,200,000 pursuant to the Credit Agreement at an interest rate of 4.75%.

On October 3, 2013, the Company signed a demand note for $450,000, which accrues interest at 6%, to John N. Hatsopoulos, the Company's Chief Executive Officer.

Based on our current operating plan, we believe existing resources, including our line of credit and cash and cash flows from operations, will be sufficient to meet our working capital requirements in the short term. As we continue to grow our business, our cash requirements are expected increase. As a result, we will need to raise additional capital through an equity offering to meet our operating and capital needs for future growth. As of November 14, 2013 the Company has raised $3,349,700 under this private placement.

Our ability to continue to access capital could be impacted by various factors including general market conditions and the continuing slowdown in the economy, interest rates, the perception of our potential future earnings and cash distributions, any unwillingness on the part of lenders to make loans to us and any deterioration in the financial position of lenders that might make them unable to meet their obligations to us. If these conditions continue and we cannot raise funds through a public or private debt financing, or an equity offering, our ability to grow our business may be negatively affected and we may need to suspend and significantly reduce our operating costs until market conditions improve.

Significant Accounting Policies and Critical Estimates

The Company’s significant accounting policies are discussed in the Notes to the Condensed Consolidated Financial Statements above and in our 2012 Annual Report. The accounting policies and estimates that can have a significant impact upon the operating results, financial position and footnote disclosures of the Company are described in the above notes and in our Annual Report.

Seasonality

We expect that the majority of our heating systems sales will be in the winter and the majority of our chilling systems sales will be in the summer. Our cogeneration and chiller system sales are not generally affected by the seasons, although customer goals will be to have chillers installed and running in the spring. Our service team does experience higher demand in the warmer months when cooling is required. These units are generally shut down in the winter and started up again in the spring. This “busy season” for the service team generally runs from May through the end of September.

Off-Balance Sheet Arrangements

On July 22, 2013, the Company’s Chief Executive Officer personally pledged to support a bank credit facility of $1,055,000 to support bank guarantees issued on certain construction contracts. We do not have any other off-balance sheet arrangements, including any outstanding derivative financial instruments, off-balance sheet guarantees, interest rate swap transactions or foreign currency contracts. We do not engage in trading activities involving non-exchange traded contracts.

Item 4. Controls and Procedures.

Management’s Evaluation of Disclosure Controls and Procedures:

Our disclosure controls and procedures are designed to provide reasonable assurance that the control system’s objectives will be met. Our management, including our Chief Executive Officer and Chief Financial Officer, after evaluating the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report, or the Evaluation Date, have concluded that as of the Evaluation Date, our disclosure controls and procedures were not effective due to material weaknesses in financial reporting relating to lack of personnel with a sufficient level of accounting knowledge and a small number of employees dealing with general controls over information technology. At the present time, our management has decided that, considering the employees involved and the control procedures in place, there are risks associated with the above, but the potential benefits of adding additional employees to mitigate these weaknesses do not justify the expenses associated with such increases. Management will continue to evaluate the above weaknesses, and as the Company grows and resources become available, the Company plans to take the necessary steps in the future to remediate the weaknesses.

For these purposes, the term disclosure controls and procedures of an issuer means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Report of Management on Internal Control over Financial Reporting:

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting in accordance with the Exchange Act. Management, including our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of our internal control over financial reporting based on the framework and criteria established in Internal Control—Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission. This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion of this evaluation. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was not effective as of September 30, 2013.

At September 30, 2013, the Company employed 62 active full-time employees and 3 part-time employees. The Company currently does not have personnel with a sufficient level of accounting knowledge, experience and training in the selection, application and implementation of generally accepted accounting principles as it relates to complex transactions and financial reporting requirements. The Company also has a small number of employees dealing with general controls over information technology security and user access. This constitutes a material weakness in financial reporting. At this time, management has decided that considering the employees involved and the control procedures in place, there are risks associated with the above, but the potential benefits of adding additional employees to mitigate these weaknesses, does not justify the expenses associated with such increases. Management will continue to evaluate the above weaknesses.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our Disclosure Controls or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of a simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

TECOGEN INC.

In connection with the evaluation referred to in the foregoing paragraph, we will make changes in our internal controls over financial reporting as soon as the resources become available. As of September 30, 2013, no changes have been made to the Company's process.
