CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

As used in this Quarterly Report on Form 10-Q, the terms “CDTi” or the “Company” or “we,” “our” and “us” refer to Clean Diesel Technologies, Inc. and its consolidated subsidiaries.

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, adopted pursuant to the Private Securities Litigation Reform Act of 1995. Forward-looking statements involve risks and uncertainties, as well as assumptions, which could cause our results to differ materially from those expressed or implied by such forward-looking statements. Forward-looking statements generally are identified by the words “may,” “will,” “project,” “might,” “expects,” “anticipates,” “believes,” “intends,” “estimates,” “should,” “could,” “would,” “strategy,” “plan,” “continue,” “pursue,” or the negative of these words or other words or expressions of similar meaning. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements. These forward-looking statements are based on information available to us, are current only as of the date on which the statements are made, and are subject to numerous risks and uncertainties that could cause our actual results, performance, prospects or opportunities to differ materially from those expressed in, or implied by, the forward-looking statements. For examples of such risks and uncertainties, please see the discussion under the caption “Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2013 filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2014 and important factors discussed in this report and our other filings with the SEC, including without limitation the following:

·       We have incurred losses, have not experienced positive cash flows from operations in the past and our independent registered public accounting firm expressed substantial doubt about our ability to continue as a going concern in their report on our financial statements for the period ended December 31, 2013. Our ability to achieve profitability and positive cash flows from operations, or finance negative cash flow from operations, could depend on reductions in our operating costs, which may not be achievable, or from increased sales, which may not occur;

·       We could require additional working capital to maintain our operations in the form of funding from outside sources which may be limited, difficult to obtain, or unavailable on acceptable terms or not available at all, or in the case of an offering of common stock or securities convertible into common stock, may result in dilution to our existing stockholders;

·       The pursuit of opportunities relating to special government mandated retrofit programs requires cash investment in operating expenses and working capital such as inventory and receivables prior to the realization of profits and cash from sales and, if we are not successful in accessing cash resources to make these investments, we may miss out on these opportunities; further, if we are not successful in generating sufficient sales from these opportunities, we will not realize the benefits of the investments in inventory, which could have an adverse effect on our business, financial condition and results of operations;

·       We cannot assure you that we will be successful in realigning our strategic path to pursue aggressive development of our unique materials science platform or that those efforts will have the intended effect of increasing profitability;

·       Historically, we have been dependent on a few major customers, particularly Honda, for a significant portion of our revenue and our revenue would decline if we are unable to maintain those relationships, if customers reduce their orders for our products, or if we are unable to secure new customers. In addition, we have an agreement with Honda that could limit our rights to commercialize certain technology which could adversely affect our technology licensing strategy;

·      We are not able to sell our current catalyst products in certain countries in Asia since such products are based on technology which we sold to a third party;

·      We have entered into contractual agreements in connection with the sale of certain of our assets, which may expose us to liability for claims for indemnification under such agreements; and

·      We depend on intellectual property and the failure to protect our intellectual property could adversely affect our future growth and success.

You should not place undue reliance on any forward-looking statements. Except as otherwise required by federal securities laws, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, changed circumstances or any other reason. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to other forward-looking statements.

1.     Organization

         a.   Description of Business

         Clean Diesel Technologies, Inc. (“CDTi” or the “Company”) is a global manufacturer and distributor of heavy duty diesel and light duty vehicle emissions control systems and products to major automakers and retrofitters. CDTi’s business is driven by increasingly stringent global emission standards for internal combustion engines, which are major sources of a variety of harmful pollutants. The Company has operations in the United States, Canada, the United Kingdom, France, Japan and Sweden as well as an Asian investment.

         b.   Liquidity

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. Therefore, the consolidated financial statements contemplate the realization of assets and liquidation of liabilities in the ordinary course of business. The Company has suffered recurring losses and negative cash flows from operations since inception, resulting in an accumulated deficit of $186.7 million at June 30, 2014. The Company has funded its operations through equity sales, debt and bank borrowings.

The Company has a $7.5 million secured demand facility backed by its receivables and inventory with Faunus Group International, Inc. (“FGI”). At June 30, 2014, the Company had $3.4 million in borrowings outstanding under this facility with $4.1 million available, subject to the availability of eligible accounts receivable and inventory balances for collateral. There is no guarantee that the Company will be able to borrow to the full limit of $7.5 million if FGI chooses not to finance a portion of its receivables or inventory. Additionally, FGI can cancel the facility at any time.

On May 15, 2012, the Company filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission (“SEC”) (the “Shelf Registration”), which was declared effective by the SEC on May 21, 2012. The Shelf Registration permits the Company to sell, from time to time, up to an aggregate of $50.0 million of various securities, provided that the Company may not sell its securities in a primary offering pursuant to the Shelf Registration or any other registration statement on Form S-3 with a value exceeding one-third of its public float in any 12-month period (unless the Company’s public float rises to $75.0 million or more).

On July 3, 2013, the Company sold 1,730,000 units pursuant to the Shelf Registration for $1.25 per unit, with each unit consisting of one share of common stock and one half of a warrant to purchase one share of common stock with an exercise price of $1.25 per share. The Company received net proceeds of $1.7 million after deducting discounts and commissions to the underwriter and offering expenses. In the first quarter of 2014, warrant holders exercised an aggregate of 800,000 of the warrants issued in the offering at an exercise price of $1.25 per share for proceeds of $1.0 million.   

On March 21, 2014, the Company and Kanis S.A. entered into a letter agreement whereby Kanis S.A. agreed not to accelerate the maturity of the Company’s 8% subordinated convertible notes due 2016 prior to July 1, 2015. See Note 8 for additional information on these notes.

On April 4, 2014, the Company sold 2,030,000 units pursuant to the Shelf Registration for $3.40 per unit, with each unit consisting of one share of common stock and 0.4 of one warrant to purchase one share of common stock with an exercise price of $4.20 per share. The Company received net proceeds of $6.1 million after deducting placement agent fees and other offering expenses. See Note 9 for additional information.

At June 30, 2014, the Company had $8.6 million in cash. Based on the Company’s current cash levels, proceeds from the April 2014 offering and expected cash flows from operations, management believes that the Company will have access to sufficient working capital to fund operations through the end of this year and into next year. However, there can be no assurances that the Company will be able to achieve projected levels of revenue and maintain access to sufficient working capital. If cash from operations is not sufficient for the working capital needs of the Company, the Company may be forced to seek additional financing in the form of funding from outside sources. However, there is no assurance that the Company will be able to raise additional funds or reduce its discretionary spending to a level sufficient for its working capital needs.

2.     Summary of Significant Accounting Policies

        a.   Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial reporting. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been reflected. The results reported in these unaudited condensed consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), but is not required for interim reporting purposes, has been condensed or omitted. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

        b.   Principles of Consolidation

The unaudited condensed consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation.

Investments in which the Company has at least a 20%, but not more than a 50% interest are generally accounted for under the equity method. Investment interests below 20% are generally accounted for under the cost method, except if the Company could exercise significant influence, the investment would be accounted for under the equity method. The Company’s judgment regarding the level of influence over each equity method investment includes considering key factors such as the Company’s ownership interest, representation on the Board of Directors, participation in policy-making decisions and material intercompany transactions. The Company includes its proportionate share of the net income or loss of equity-method investees in its unaudited condensed consolidated statements of comprehensive loss.

c.   Use of Estimates

 The preparation of financial statements in conformity with U.S. GAAP requires management of the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. These estimates and assumptions are based on management’s best estimates and judgment. On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to impairment of goodwill and long-lived assets, stock-based compensation, the fair value of financial instruments including warrants, allowance for doubtful accounts, inventory valuation, taxes and contingent and accrued liabilities. The Company bases its estimates on historical experience and various other factors, including the current economic environment, which it believes to be reasonable under the circumstances. Estimates and assumptions are adjusted when facts and circumstances dictate. Actual results may differ from these estimates under different assumptions and conditions. Management believes that the estimates are reasonable.

d.   Concentration of Risk

For the three and six months ended June 30, 2014, one automotive original equipment manufacturer (“OEM”) customer within the Catalyst segment accounted for 43% and 42%, respectively, of the Company’s revenues. This customer accounted for 41% of the Company’s revenues for the three and six months ended June 30, 2013. This customer accounted for 31% and 24% of the Company’s accounts receivable at June 30, 2014 and December 31, 2013, respectively. Another customer accounted for 10% of the Company’s accounts receivable at June 30, 2014. No other customers accounted for 10% or more of the Company’s revenues or accounts receivable for these periods.    

For the periods presented below, certain vendors accounted for 10% or more of the Company’s raw material purchases as follows:

	Three Months Ended		Six Months Ended
	June 30,		June 30,
Vendor	2014	2013	2014	2013
A	7%	17%	17%	15%
B	19%	20%	24%	18%
C	10%	8%	10%	13%
D	12%	12%	13%	13%

Vendor A above is a catalyst supplier, vendors B and D above are substrate suppliers and vendor C is a rare earth materials supplier.

        e.    Net Loss per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of common shares and dilutive potential common shares. Dilutive potential common shares include employee stock options and restricted share units (“RSUs”) and warrants and debt that are convertible into the Company’s common stock.

Diluted net loss per share excludes certain dilutive potential common shares outstanding as their effect is anti-dilutive. Because the Company incurred net losses in the three and six months ended June 30, 2014 and 2013, the effect of potentially dilutive securities has been excluded in the computation of net loss per share and net loss from continuing operations per share as their impact would be anti-dilutive. Potentially dilutive common stock equivalents excluded were 2.3 million shares during each of the three months ended June 30 2014 and 2013. Potentially dilutive common stock equivalents excluded were 2.1 million and 2.2 million shares during the six months ended June 30 2014 and 2013, respectively.  

          f.   Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value in accordance with a hierarchy which requires an entity to maximize the use of observable inputs which reflect market data obtained from independent sources and minimize the use of unobservable inputs. There are three levels of inputs that may be used to measure fair value:

·  Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities;

·  Level 2: Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable including quoted prices for similar instruments in active markets and quoted prices for identical or similar instruments in markets that are not active; and

·  Level 3: Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.

The Company records its liability-classified warrants at fair value in accordance with the fair value measurement framework. See Note 10 for further information on these liability-classified warrants. The valuation inputs hierarchy classification for the warrant liability measured at fair value on a recurring basis is summarized as follows (in thousands):

Warrant liability	Level 1	Level 2	Level 3
As of June 30, 2014	-	-	$	1,647
As of December 31, 2013	-	-	$	939

The following is a reconciliation of the warrant liability measured at fair value using Level 3 inputs (in thousands):

	Six Months Ended June 30,
	2014		2013
Balance at beginning of period	$	939	$	10
Issuance of common stock warrants		1,531		-
Exercise of common stock warrants		(2,505)		-
Remeasurement of common stock warrants		1,682		(6)
Balance at end of period	$	1,647	$	4

         g.   Fair Value of Financial Instruments

Accounting Standards Codification (“ASC”) Topic 825, “Financial Instruments,” requires disclosure of the fair value of financial instruments for which the determination of fair value is practicable. The fair values of the Company’s cash, trade accounts receivable, prepaid expenses and other current assets, accounts payable and accrued expenses and other current liabilities approximate carrying values due to the short maturity of these instruments. The fair value of borrowings under the line of credit approximates their carrying value due to the variable interest rates. The fair value of shareholder notes payable calculated using level 3 inputs, using a Black-Scholes option-pricing model to value the debt’s conversion factor and a net present value model was $7.5 million at June 30, 2014 and December 31, 2013.

h.   Reclassifications

Certain prior-period amounts have been reclassified to conform to the current period presentation. These changes had no impact on the previously reported consolidated results of operations or stockholders' equity.

i.   Recent Accounting Pronouncements  

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. The Company does not expect the impact of the adoption of ASU 2014-08 to be material to its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)", and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements.

Line of Credit with FGI

The Company has a $7.5 million secured demand facility with FGI backed by its receivables and inventory (as amended, the “FGI Facility”). The FGI Facility expires on August 15, 2015 and may be extended at the Company’s option for additional one-year terms. However, FGI can cancel the facility at any time.

Under the FGI Facility, FGI can elect to purchase eligible accounts receivables from the Company and certain of its subsidiaries at up to 80% of the value of such receivables (retaining a 20% reserve). Purchased receivables are subject to full recourse to the Company in the event of nonpayment by the customer. FGI becomes responsible for the servicing and administration of the accounts receivable purchased. The Company is not obligated to offer accounts in any month and FGI has the right to decline to purchase any accounts. At FGI’s election, FGI may advance the Company up to 80% of the value of any purchased accounts receivable, subject to the $7.5 million limit. Reserves retained by FGI on any purchased receivable are expected to be refunded to the Company net of interest and fees on advances once the receivables are collected from customers. The Company may also borrow against eligible inventory up to the inventory sublimit, as determined by FGI, subject to the aggregate $7.5 million limit under the FGI Facility and certain other conditions. At June 30, 2014, the inventory sublimit amount was the lesser of $1.5 million or 50% of the aggregate purchase price paid for accounts receivable purchased under the FGI facility. While the overall credit limit and the inventory sublimit were not changed, in the second quarter of 2014, borrowing against the Company’s significant OEM customer’s inventory has been limited to $0.2 million by FGI due to their concerns about customer concentration.

The interest rate on advances or borrowings under the FGI Facility is the greater of (i) 6.50% per annum and (ii) 2.50% per annum above the prime rate, as defined in the FGI Facility and was 6.50% at June 30, 2014 and December 31, 2013. Any advances or borrowings under the FGI Facility are due on demand. The Company also agreed to pay FGI collateral management fees of 0.30% per month on the face amount of eligible receivables as to which advances have been made and 0.38% per month on borrowings against inventory, if any. At any time outstanding advances or borrowings under the FGI Facility are less than $2.4 million, the Company agreed to pay FGI standby fees of (i) the interest rate on the difference between $2.4 million and the average outstanding amounts and (ii) 0.44% per month on 80% of the amount by which advances or borrowings are less than the agreed $2.4 million minimum.   

At June 30, 2014, the Company had $3.2 million of gross accounts receivable pledged to FGI as collateral for short-term debt in the amount of $2.6 million. At June 30, 2014, the Company also had $0.8 million in borrowings outstanding against eligible inventory. The Company was in compliance with the terms of the FGI Facility at June 30, 2014. However, there is no guarantee that the Company will be able to borrow to the full limit of $7.5 million if FGI chooses not to finance a portion of its receivables or inventory.

$1.5 Million, 8% Shareholder Note Due 2015

On December 30, 2010, the Company executed a Loan Commitment Letter with Kanis S.A., a shareholder of the Company, pursuant to which Kanis S.A. loaned the Company $1.5 million. The unsecured loan, as amended, bears interest on the unpaid principal at a rate of 8%, with interest only payable quarterly in arrears. In addition to principal and accrued interest, the Company is obligated to pay Kanis S.A. “Payment Premium” of $250,000 with $100,000 paid on June 30, 2013 and the remaining amount payable on the June 30, 2015 maturity date. There is no prepayment penalty.

$3.0 Million, 8% Subordinated Convertible Shareholder Notes Due 2016

On April 11, 2011, the Company entered into a Subordinated Convertible Notes Commitment Letter with Kanis S.A. that provides for the sale and issuance by the Company of 8% subordinated convertible notes (the “Notes”). As provided in the Commitment Letter, on May 6, 2011 Kanis S.A. purchased from the Company at par $3.0 million aggregate principal amount of the Notes, which bear interest at a rate of 8% per annum, payable quarterly in arrears.

The Notes have a stated maturity of five years from the date of issuance. The agreement, as amended, allows for the acceleration of the maturity of the Notes if: (i) the Company was in breach of the Notes or other agreements with Kanis S.A., or (ii) Kanis S.A. provided written notice, not less than 30 days prior to such date, that it elected to accelerate the maturity to a date not earlier than May 12, 2013. On March 21, 2014, the Company and Kanis S.A. entered into a letter agreement whereby Kanis S.A. agreed not to accelerate the maturity of these Notes prior to July 1, 2015. The Notes have been classified as noncurrent in the unaudited condensed consolidated balance sheets at June 30, 2014 and December 31, 2013.

The Notes also provide that the Company has the option to redeem the Notes at any time at a price equal to 100% of the face amount plus accrued and unpaid interest through the date of redemption. There is no prepayment penalty. The Notes are unsecured obligations of the Company and subordinated to existing and future secured indebtedness of the Company.

(Unaudited)

As amended, the outstanding principal balance of the Notes, and accrued and unpaid interest are convertible, at the option of Kanis S.A., at any time upon written notice given not less than 75 calendar days prior to the date of conversion, into no more than 250,000 shares of the Company’s common stock at a conversion price of $4.00 per share.

$3.0 Million, 8% Shareholder Note Due 2015

On July 27, 2012, the Company executed a Loan Commitment Letter with Kanis S.A., pursuant to which the Company issued an unsecured promissory note in the principal amount of $3.0 million, which bears interest at 8% per annum, payable quarterly in arrears. The promissory note matures on July 27, 2015. There is no prepayment penalty or premium.

9.    Stockholders’ Equity

Significant Changes in Stockholders’ Equity

During the six months ended June 30, 2014, additional paid-in capital increased by $9.0 million. $8.2 million of this increase is attributable to (i) $4.7 million in proceeds, net of costs, from a recent registered offering, (ii) $1.0 million in proceeds received from the exercise of warrants to purchase a total of 800,000 shares of the Company’s common stock and (iii) $2.5 million being the fair value of these warrants reclassified from liabilities. Refer to the April 2014 Offering discussion below and Note 10 for additional information.

Shelf Registration

On May 15, 2012, the Company filed a Shelf Registration which was declared effective by the SEC on May 21, 2012. The Shelf Registration permits the Company to sell, from time to time, up to an aggregate of $50.0 million of various securities, including common stock, preferred stock, warrants to purchase common stock or preferred stock and units consisting of one or more shares of common stock, shares of preferred stock, warrants, or any combination of such securities. However, the Company may not sell its securities in a primary offering pursuant to the Shelf Registration or any other registration statement on Form S-3 with a value exceeding one-third of its public float in any 12-month period (unless the Company’s public float rises to $75.0 million or more). The Shelf Registration is intended to provide the Company with additional flexibility to access capital markets for general corporate purposes, subject to market conditions and the Company's capital needs.

April 2014 Offering

On April 1, 2014, the Company entered into a placement agent agreement with Roth Capital Partners, LLC and Craig-Hallum Capital Group LLC related to the registered direct offering (the “Offering”) of an aggregate of 2,030,000 shares of the Company’s common stock together with warrants to purchase up to 812,000 shares of common stock. The Offering was made pursuant to the Company’s Shelf Registration discussed above. On April 4, 2014, the Company closed the Offering in which it sold 2,030,000 shares of common stock and warrants to purchase 812,000 shares of common stock. The shares of common stock and warrants were sold in units at $3.40 per unit, with each unit consisting of one share of common stock and 0.4 of one warrant to purchase one share of common stock at an exercise price of $4.20 per share.

The Company received gross proceeds of $6.9 million and net proceeds of $6.1 million after deducting placement agent fees and other offering expenses. The Offering warrants are within the scope of ASC 815-40 and are required to be recorded as liabilities (see note 10). Accordingly, of the $6.1 million in net proceeds, $4.6 million was allocated to the common stock and included in additional paid-in capital and $1.5 million was allocated to the warrant liability based on the fair value of the warrants on the issuance date. Additionally, $0.2 million of the placement agent fees and other offering costs were allocated to the Offering warrants, based on the relative fair value of the Offering warrants and the common stock on the issuance date, and is included in other expense, net in the accompanying statement of comprehensive loss for the three and six months ended June 30, 2014. The Company intends to use the proceeds for general corporate purposes, which may include working capital, general and administrative expenses, capital expenditures and implementation of its strategic priorities. The Company may also use a portion of the net proceeds to acquire or invest in businesses, products and technologies that are complementary to its current business, although there are no present commitments or agreements for any such transactions.

Common Stock Purchase Agreement with Lincoln Park Capital ("LPC")

On October 7, 2011, the Company signed a Purchase Agreement with LPC, together with a Registration Rights Agreement, whereby LPC agreed to purchase up to $10.0 million of the Company’s common stock over a 30-month period ending April 24, 2014. This expired unused in April 2014.

10.  Warrants

From time to time, the Company issues warrants to purchase its common stock. These warrants have been issued for consulting services, in connection with the Company’s issuance of debt and sales of its common stock.

Warrant activity is summarized as follows:  

		Weighted Average Exercise Price
				Range of Exercise Prices
	Shares
Outstanding at December 31, 2013	1,139,535	$	1.68	$1.25 - $10.40
Warrants issued	812,000	$	4.20	$4.20
Warrants exercised	(800,000)	$	1.25	$1.25
Outstanding at June 30, 2014	1,151,535	$	3.76	$1.25 - $10.40
Warrants exercisable at June 30, 2014	319,535	$	3.03	$1.25 - $10.40

Warrant Liability

The Company evaluates warrants on issuance and at each reporting date to determine proper classification as equity or as a liability. The Company’s warrant liability is carried at fair value and is classified as Level 3 in the fair value hierarchy because the warrants are valued based on unobservable inputs.

The Company determines the fair value of its warrant liability using the Black-Scholes option-pricing model unless the awards are subject to market conditions, in which case it uses a Monte Carlo simulation model, which utilizes multiple input variables to estimate the probability that market conditions will be achieved. These models are dependent on several variables such as the instrument’s expected term, expected strike price, expected risk-free interest rate over the expected term of the instrument, expected dividend yield rate over the expected term and the expected volatility. The expected strike price for warrants with full-ratchet down-round price protection is based on a weighted average probability analysis of the strike price changes expected during the term as a result of the full-ratchet down-round price protection. Due to the significant change in the Company following its business combination with Catalytic Solutions, Inc. (the “Merger”), CDTi’s pre-Merger historical price volatility was not considered representative of expected volatility going forward. Therefore, the Company has used an estimate based upon a weighted average of implied and historical volatility of a portfolio of peer companies and CDTi’s post-Merger historical volatility for the valuation of its warrants. The expected life is equal to the remaining contractual life of the warrants.

The Offering warrants require physical settlement by delivering registered shares. In addition, while the relevant warrant agreement does not require cash settlement if the Company fails to maintain registration of the warrant shares, it does not specifically preclude cash settlement. Accordingly, the Company’s agreement to deliver registered shares without express terms for settlement in the absence of continuous effective registration is presumed to create a liability to settle these warrants in cash, requiring liability classification. The assumptions used in the Black-Scholes option-pricing model to estimate the fair value of the warrant liability for these warrants are as follows:

	June 30, 2014		April 4, 2014
Warrants valued		812,000		812,000
CDTi stock price	$	2.71	$	2.95
Strike price	$	4.20	$	4.20
Expected volatility		84.5%		84.9%
Risk-free interest rate		1.7%		1.9%
Dividend yield		─		─
Expected life in years		5.3		5.5

The assumptions used in the Monte Carlo simulation model to estimate the fair value of the warrant liability for warrants with full-ratchet down-round protection are as follows:

	June 30, 2014		December 31, 2013
Warrants valued		159,000		959,000
CDTi stock price	$	2.71	$	1.51
Strike price	$	1.25	$	1.25
Expected volatility		76.5%		73.6%
Risk-free interest rate		1.3%		1.8%
Dividend yield		─		─
Expected life in years		4.0		4.5

The warrant liability, included in accrued expenses and other current liabilities in the accompanying unaudited condensed consolidated balance sheets, is re-measured at the end of each reporting period with changes in fair value recognized in other expense in the unaudited condensed consolidated statements of comprehensive loss. Upon the exercise of a warrant that is classified as a liability, the fair value of the warrant exercised is re-measured on the exercise date and reclassified from warrant liability to additional paid-in capital. The Company recorded other income of $0.4 million for the three months ended June 30, 2014 as a result of the change in fair value of the warrant liability, which was primarily due to a decrease in the Company’s stock price during this period. The Company recorded other expense of $1.7 million for the six months ended June 30, 2014 as a result of the change in fair value of the warrant liability which was primarily due to an increase in the Company’s stock price during the reporting period. During the six months ended June 30, 2014, as a result of the exercise of warrants to purchase 800,000 shares of the Company’s common stock, the warrant liability decreased $2.5 million, excluding the effects of remeasurement, with an offsetting increase to additional paid-in capital.

11.  Stock-Based Compensation

 The Clean Diesel Technologies, Inc. Stock Incentive Plan, as amended (the “Plan”), provides for the awarding of incentive stock options, non-qualified stock options, stock appreciation rights, restricted shares, performance awards, bonuses or other forms of share-based awards, or combinations of these to the Company’s directors, officers, employees, consultants and advisors (except consultants or advisors in capital-raising transactions) as determined by the Board of Directors. As of June 30, 2014, there were 136,936 shares available for future grants under the Plan.

 Total stock-based compensation expense for the three months ended June 30, 2014 and 2013 was $0.2 million. Total stock-based compensation expense for the six months ended June 30, 2014 and 2013 was $0.3 million and $0.4 million, respectively. Compensation expense is recognized on a straight-line basis over the requisite service period for all stock-based awards made to employees and directors in the unaudited condensed consolidated statements of comprehensive loss.

12.   Joint Venture

On February 19, 2013, the Company entered into a joint venture agreement (the “Joint Venture Agreement”) with Pirelli & C. Ambiente SpA (“Pirelli”) to form a joint venture entity, Eco Emission Enterprise Srl under the laws of Italy (the “Joint Venture”), through which the Company and Pirelli would jointly sell their emission control products in Europe and the Commonwealth of Independent States countries. The Joint Venture commenced operations in April 2013.

On November 8, 2013, as a result of slower than anticipated progress in achieving sales objectives initially established for the Joint Venture, the Company and Pirelli agreed to voluntarily dissolve the Joint Venture in accordance with the Joint Venture Agreement. The Joint Venture ceased operations on November 30, 2013 and commenced liquidation on December 9, 2013. The dissolution was finalized in April 2014. The majority of its investment balance of $0.1 million, included in other assets in the accompanying unaudited condensed consolidated balance sheets December 31, 2013, was received in April 2014, with a small balance to be collected following the receipt of VAT due from the Swedish and Italian governments. The Company has resumed its operations in Europe in a similar manner as conducted prior to the Joint Venture.

13.   Commitments and Contingencies

Legal Proceedings

On April 30, 2010, the Company received notice of an administrative complaint filed by its former chief financial officer. The complaint was filed with the Hartford, Connecticut office of the U.S. Department of Labor (“U.S. DOL”) under Section 806 of the Sarbanes-Oxley Act of 2002 (“SOX”) and alleged, among other things, that the Company’s termination of her employment on April 19, 2010 was retaliatory and due to her alleged protected activity associated with comments she made to the Company’s Board of Directors at their meeting on March 26, 2010. On June 14, 2010, the Company filed its response to the complaint denying the allegations and requesting a dismissal of the matter. On September 27, 2013, the U.S. DOL issued preliminary findings on the matter concluding there was reasonable cause to support the former employee’s claims and ordering the Company to pay damages in excess of $1.9 million and take certain other actions. On October 22, 2013, the Company filed its Objections and Request for Hearing with the U.S. DOL which triggered the appointment of an Administrative Law Judge (“ALJ”), and the scheduling of a hearing on the merits of the matter. Thereafter, the parties agreed to participate in a U.S. DOL mediation process on February 7, 2014. On March 13, 2014, the parties entered into a settlement agreement which provided for payment of a one-time lump sum amount of $0.4 million to the former employee, along with issuance of 75,000 shares of Company stock. The settlement was formally approved by the ALJ. As a result, there were mutual releases of all claims and a dismissal of the SOX complaint. The Company reserved $0.6 million at December 31, 2013, which included the lump sum amount, the market value of the common stock and accrued legal expenses incurred. The settlement was paid and stock issued in April 2014, and the Company recorded an additional $0.1 million related to the increase in the fair value of its common stock at the time of issuance.

On November 15, 2013, BP Products North America (“BP”) instituted claims against Johnson Matthey (“JM”) as the parent company of and purchaser of Applied Utility Systems, Inc. (“AUS”), a former subsidiary of the Company. On May 12, 2010, JM tendered to the Company a claim for indemnification under the Asset Purchase Agreement dated October 1, 2009, (the “Asset Purchase Agreement”), among JM, the Company and AUS. On June 11, 2013, BP, JM and the Company entered into a Settlement Agreement and Mutual Release pursuant to which they settled all claims. The settlement agreement had no material impact on the Company. Under the indemnification clauses of the Asset Purchase Agreement, the Company may be liable for legal expenses incurred by JM. These legal costs may be offset against funds withheld by JM from the acquisition of AUS.

In connection with the Asset Purchase Agreement, on October 1, 2009, JM presented the Company with an indemnification claim seeking recovery of the net amount of $0.9 million after offsetting the funds withheld by JM from the acquisition of AUS. These claims are for matters relating to various customer contracts that JM purchased, including the BP contract discussed above. The Company and JM have entered into discussions relating to the application of offsets and the validity of the claims presented. The Company has offered a settlement amount of $0.2 million and has reserved for this amount since the fourth quarter of 2013. Since the discussions are ongoing, the ultimate costs associated with this matter cannot be determined at this time.

In addition to the foregoing, the Company is involved in legal proceedings from time to time in the ordinary course of its business. Management does not believe that any of these claims and proceedings against it are likely to have, individually or in the aggregate, a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows. Accordingly, the Company cannot determine the final amount, if any, of its liability beyond the amount accrued in the unaudited condensed consolidated financial statements as of June 30, 2014, nor is it possible to estimate what litigation-related costs will be in the future.

Sales and Use Tax Audit

The Company is undergoing a sales and use tax audit by the State of California (the "State") on AUS for the period of 2007 through 2009. The audit has identified a project performed by the Company during that time period for which sales tax was not collected and remitted and for which the State asserts that proper documentation of resale may not have been obtained and that the Company owes sales tax of $1.4 million. The Company contends and believes that it received sufficient and proper documentation from its customer to support not collecting and remitting sales tax from that customer and is actively disputing the audit report with the State. On August 12, 2013, the Company appeared at an appeals conference with the State Board of Equalization ("BOE"). On July 21, 2014, the Company received a Decision and Recommendation (“D&R”) from the BOE. The D&R’s conclusion was that the basis for the calculation of the aforementioned $1.4 million tax due should be reduced from $12.2 million to $9.0 million with a commensurate reduction in the tax owed to the State. Regardless of this finding, the Company continues to believe that it will prevail in this matter, as it believes that the State did not adequately address the legal arguments related to the Company’s acceptance of the valid resale certificate from its customer. The Company has not agreed to these findings, and therefore, it will be appealing at a higher level at the BOE. Accordingly, no accrual has been recorded for this matter as the Company does not assess a loss as being probable. Should the Company not prevail in this matter, it will pursue reimbursement from the customer for all assessments from the State.

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

 The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q. This Quarterly Report on Form 10-Q should also be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2013. This discussion contains forward-looking statements, the accuracy of which involves risks and uncertainties, see “Cautionary Note Concerning Forward-Looking Statements” at the beginning of this Quarterly Report on Form 10-Q. Our actual results could differ materially from those anticipated in these forward-looking statements for many reasons, as a result of many important factors, including those set forth in Part I — Item 1A “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

References to “Notes” are notes included in the unaudited condensed consolidated financial statements included elsewhere in the Quarterly Report on Form 10-Q.

Overview

We are a leading technology-focused, global manufacturer and distributor of light duty vehicle catalysts and heavy duty diesel emissions control systems and products to major automakers, integrators and retrofitters. We have more than 13 years history of supplying catalysts to light duty vehicle original equipment manufacturers, or OEMs, and over 30 years of experience in the heavy duty diesel systems market. We have a proven technical and manufacturing competence in the light duty vehicle catalyst market meeting automakers’ stringent requirements for performance, quality and delivery. Our business is driven by increasingly stringent global emission standards for internal combustion engines, which are major sources of a variety of harmful pollutants. Since inception, we have developed a substantial portfolio of patents and related proprietary rights and extensive technological know-how.

 We organize our operations in two business divisions or reportable segments: the Heavy Duty Diesel Systems division and the Catalyst division.

Heavy Duty Diesel Systems: Our Heavy Duty Diesel Systems division specializes in the design and manufacture of verified exhaust emissions control solutions. This division offers a full range of products for the verified retrofit and non-retrofit OEM and aftermarket markets through its distribution/dealer network and direct sales. Our DuraFit™, Purifilter^®, Purifier™, Combifilter ^®, Cattrap ^® and Actifilter™ products, along with our catalyst technologies, are used to reduce exhaust emissions created by on-road, off-road and stationary diesel, and alternative fuel engines including propane and natural gas. We also provide Platinum Plus ^® fuel-borne catalyst technology, ARIS ^® airless return flow system technology and exhaust gas recirculation with selective catalyst reduction technologies. Revenues from our Heavy Duty Diesel Systems division accounted for approximately 57% and 56% of the total consolidated revenues for the six months ended June 30, 2014 and 2013, respectively.

Catalyst: Our Catalyst division develops and produces catalysts to reduce emissions from gasoline, diesel and natural gas combustion engines. Most catalytic systems require significant amounts of costly platinum group metals, or PGMs, to operate efficiently. Using our proprietary mixed-phase catalyst, or MPC ^®, technology, we have developed a family of unique high-performance catalysts, featuring inexpensive base-metals with low or even no PGM content. Our technical and manufacturing capabilities have been established to meet auto makers’ most stringent requirements. Since 2001, we have supplied over eleven million parts to light duty vehicle customers. Our Catalyst division also provides catalyst products for our Heavy Duty Diesel Systems division. Revenues from our Catalyst division accounted for approximately 43% and 44% of the total consolidated revenues for the six months ended June 30, 2014 and 2013, respectively. 

We are headquartered, in Oxnard, California and have operations in the United States, Canada, the United Kingdom, France, Japan and Sweden. We also have an Asian investment. Our proprietary catalyst products are manufactured at our facility in Oxnard, California and our heavy duty diesel systems and products are manufactured at our facilities in Reno, Nevada; Thornhill, Canada; and Malmö, Sweden.   

Strategic Plan

In the second quarter of 2013, our Board of Directors and management team conducted a strategic review of our business and determined to pursue aggressive development of our unique materials science platform, which we view as the most likely path to enhance growth and improve shareholder value over the long-term. The new strategy is intended to build on recent initiatives and announcements, including an increased focus on developing and patenting our proprietary advanced low-PGM and zero-PGM, or ZPGM, catalysts. We believe our disruptive technology provides a solution to OEMs that contrasts with current solutions; one that reduces the dependence upon increasingly costly and scarce PGMs to meet stringent emission standards, such as the U.S. Environmental Protection Agency’s (the “EPA”) Tier 3 light duty vehicle emission standards. Our strategy includes combining our manufacturing expertise with advanced low-PGM and ZPGM materials to develop advanced catalysts in powder form to allow for potentially broader distribution and delivery options resulting in new commercial opportunities. We intend to pursue licensing and partnership arrangements to accelerate the commercialization of our patented and proprietary materials technology. Based on our strategic review, we have defined our near-term strategic priorities as follows:

18

·  Explore strategic options to maximize the value of our existing manufacturing assets and business;

·  Focus our research and development efforts on technology development, patent protection and commercialization of new advanced low-PGM and ZPGM materials and robust manufacturing process technology;

·  Aggressively build our patent portfolio to maintain and protect our technology leadership position;

·  Develop and qualify emission catalysts for a variety of applications in multiple segments of the emissions control market;

·  Seek customers or partners for core emission control technology via development partnerships, licensing, joint venture or manufacturing agreements and pursue short-term catalyst sales opportunities; and

·  Pursue new end markets, including fuel cells, petro-chemicals and thermo-electrics.

Recent Developments

Equity Financing

On April 4, 2014, we closed a registered direct offering in which we sold 2,030,000 shares of common stock and warrants to purchase 812,000 shares of common stock. The securities were sold in units at $3.40 per unit, with each unit consisting of one share of common stock and 0.4 of a warrant to purchase one share of common stock. The warrants have an exercise price of $4.20 per share and can be exercised during the period commencing after six months and ending five and a half years from the date of issuance. We received net proceeds of $6.1 million after deducting placement agent fees and other offering expenses. We plan to use the proceeds for general corporate purposes, including working capital, general and administrative expenses, capital expenditures and implementation of our strategic priorities. We may also use a portion of the net proceeds to acquire or invest in businesses, products and technologies that are complementary to our current business, although we have no present commitments or agreements for any such transactions.

Letter Agreement related to $3.0 million, 8% subordinated convertible note due 2016

On March 21, 2014, we and Kanis S.A. entered into a letter agreement regarding our outstanding 8% subordinated convertible note due 2016 whereby Kanis S.A. has agreed not to accelerate the maturity of these notes prior to July 1, 2015. See Note 8 for more information relating to the terms of our 8% subordinated convertible note due 2016.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures in the financial statements. Critical accounting policies are those accounting policies that may be material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change, and that have a material impact on financial condition or operating performance. While we base our estimates and judgments on our experience and on various other factors that we believe to be reasonable under the circumstances, actual results may differ from these estimates under different assumptions or conditions.

We believe that the assumptions, judgments and estimates involved in the accounting for revenue recognition, allowance for doubtful accounts, inventory valuation, product warranty reserves, accounting for income taxes, goodwill, impairment of long-lived assets other than goodwill, stock-based compensation and warrant derivative liability have the greatest potential impact on our unaudited condensed consolidated financial statements. Please refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for our year ended December 31, 2013 for a more complete discussion of our critical accounting policies and estimates.

Factors Affecting Future Results

Government Funding and Standards

The nature of our business is heavily influenced by government funding of emissions control projects and increased emission control regulations and mandates. Compliance with these regulatory initiatives drives demand for our products and the timing of the implementation of emission reduction projects. We believe that, due to the constant focus on the environment and clean air standards throughout the world, it can be expected that new and more stringent regulations, both domestically and abroad, will continually be adopted, requiring the ongoing development of new products that meet these standards. However, emission reduction programs are often one-off, or have staggered compliance dates, which mean they do not generally result in a regular source of recurring revenues for our company.

The California Air Resources Board (“CARB”) has mandated that all Class 7 and Class 8 heavy diesel trucks meet certain emission targets by 2016, with interim targets established for 2011, 2012 and 2013, such that 90% of current operating diesel trucks will be required to meet these targets by 2014. Based on figures available from CARB and the Manufacturers of Emission Controls Associations (“MECA”), we estimate that during 2014 to 2016, potentially 28,000 heavy duty diesel trucks have yet to be replaced or retrofitted. We believe that the rate of adoption of electing to retrofit by truck owners as well as the overall level of retrofit activity and our ability to gain sales are dependent upon several factors, including the level of enforcement of the mandate by CARB, the level of new truck acquisitions by truck owners and also our success in attaining the required verifications and approvals for products currently under review by CARB. In 2012, we experienced a slower than anticipated ramp-up in adoption by truck owners, a delay in enforcement by CARB and a delay in verification for a product which was under review by CARB. This resulted in weaker than expected sales in 2012. CARB began to actively enforce the regulation in the latter part of 2012. In January 2013, we received the product verification from CARB. In addition, a key competitor exited the market. As a result of these factors, we experienced a stronger year in 2013 as compared to 2012 and had $13.4 million of sales in California. In December 2013, CARB extended the compliance deadline from December 31, 2013 to June 30, 2014 for some vehicles. Previously it was expected that sales of products in California would peak in 2013 and drop off rapidly in 2014 and 2015. Due to the extended compliance deadline, while sales in 2014 are still expected to be lower than 2013, the year over year drop off is not expected to be as steep as previously expected.

Emerging Aftermarket in North America

According to market analysis firm Power System Research, manufacturers in North America have produced an average of 250,000 heavy duty on-road diesel vehicles equipped with diesel particulate filters each year since 2007 to comply with EPA requirements. The typical OEM warranty on diesel particulate filters is 5 years and has expired for many of these vehicles with more continuing to expire in the coming years. As 2007 and newer diesel particulate filters from OEMs fail and require replacement, aftermarket diesel particulate filters will be needed as replacements. According to a 2012 industry report, the market for medium and heavy duty vehicle after-treatment maintenance and repair is projected to grow from $0.5 billion in 2010 to $3.0 billion by 2017. In the second quarter of 2014, we introduced the CDTi manufactured DuraFit™ OEM replacement diesel particulate filters through our channel of distributors to provide an alternative to OEM manufactured parts. We expect sales from this activity to be modest in 2014, with increased sales in 2015 and beyond.

Dependency on a Few Major Customers

Historically, we have derived a significant portion of our revenue from a limited number of customers. For example, sales to Honda accounted for approximately 42% of our revenue for the six months ended June 30, 2014 and 39% of our revenue for the year ended December 31, 2013. While we continually seek to broaden our customer base, it is likely that for the foreseeable future we will remain dependent on Honda to supply a substantial portion of our revenue. Manufacturers typically seek to have two or more sources of critical components. However, there can be no assurance that manufacturers for which we are a shared supplier will not sole source the products we supply. Once our product is designed into a vehicle model, we generally supply our component for the life of that model. There can be no assurance, however, that our customers will retain us for a full model term. In this regard, relationships with our customers are based on purchase orders rather than long-term formal supply agreements and customers can discontinue or materially reduce orders without warning or penalty. In addition, while new models tend to remain relatively stable for a few years, there can be no assurance that manufacturers will not change models more rapidly, or change the performance requirements of components used in those models, and use other suppliers for these new or revised models.

20

Macroeconomic Factors Impacting the Automotive Industry

Demand for our products is tied directly to the demand for vehicles. Accordingly, factors that affect the truck and automobile markets have a direct effect on our business, including factors outside of our control, such as vehicle sales slowdowns due to economic concerns, or as a result of natural disasters, including earthquakes and/or tsunamis. The loss of one or more of our significant customers, or reduced demand from one or more of our significant customers, particularly Honda, would result in an adverse effect on our revenue, and could affect our ability to become profitable or continue our business operations. 

Since the customers of our Catalyst division are primarily OEM auto makers, our Catalyst division is generally affected by macroeconomic factors impacting the automotive industry. During 2013, sales to Honda, our largest OEM auto customer, were positively impacted due to increased vehicle shipments, expansion of our catalysts onto new vehicle platforms and increased purchasing by Honda due to their increased auto sales. In addition, our sales and gross margins are also impacted by the pass-through sales of rare earth materials and the extent to which the price increases are shared with Honda. However, the formula for determining these shared costs is based on published indices of rare earth prices and, as such, we could experience margin reductions if the formula does not accurately reflect our actual costs.

Technology Strategy

Our strategic focus on developing our ZPGM catalyst technology has resulted in what we believe to be a number of significant patent filings since the first quarter of 2013. It is our intention to invest in developing and commercializing our advanced low-PGM and ZPGM catalyst technologies. As a consequence, we anticipate that we will continue to expand our intellectual property portfolio with additional patents in 2014. In addition, we will invest in other development and marketing activities, including hiring of personnel, and incurring outside testing and consulting expenses in support of our technology strategy that could result in higher operating expenses.

We remain dependent on our primary customer, Honda, for which we provide catalyst solutions. Our business with Honda has grown steadily in the last few years as we have expanded the sale of our catalyst solutions from two passenger vehicle models in 2011 to six models in 2013. We expect to see continued expansion in 2014. In conjunction with our longstanding relationship with Honda, we entered into a joint research agreement with the motorcycle division of Honda regarding the development of ZPGM catalysts for motorcycles. The agreement was signed in 2010, extended in 2012 and expired in March 2014, although confidentiality provisions continue to survive. The agreement provides that technology within the scope of the agreement developed solely by one party is owned by that party, and that technology within the scope of the agreement that is jointly developed by both parties is jointly owned. The parties are in the process of assessing what technology, if any, developed during the term of the agreement is jointly owned. To the extent that Honda is a joint owner of critical technology developed under the agreement, Honda (including its automotive division) might not be required to pay us a license or royalty fee for use of the jointly owned technology; Honda may be able to manufacture its own catalysts based on the jointly owned technology; and Honda may be able to license the jointly owned technology to others without our consent. In addition, under the terms of the agreement, we may not be able to license jointly owned technology to others without Honda’s consent. Our inability to license jointly owned technology to others could adversely affect our technology licensing strategy. Further, as noted above, we do not have long-term supply agreements with Honda, and accordingly, Honda could terminate its relationship with us at any time for any reason. For additional information on another set of agreements that could affect our relationship with Honda, see “Item 1A. Risk Factors—We are not able to sell our current products in certain countries in Asia since products are based on technology which we sold to a third party” included in our Annual Report on Form 10-K for the year ended December 31, 2013.

Supply of Catalyst Division Products to Heavy Duty Diesel Systems Division

Our strategy is to progressively utilize the products of our Catalyst division in the products of our Heavy Duty Diesel Systems division. We anticipate that our intercompany sales of catalysts will increase compared to historical levels, as we commence sales in the heavy duty diesel aftermarket and as our planned new products are approved by regulatory agencies and begin to generate sales. While this will not impact our reported sales, we believe that the manufacturing gross margin associated with these sales will improve our total gross margin.

       Selling, general and administrative expenses

The decrease in selling, general and administrative expenses was primarily due to a $0.3 million gain on the sale of a building at one of our foreign locations and $0.1 million of savings due to employee related costs.

Research and development expenses

The increase in research and development was primarily due to development work and outside testing related to new products and consultant costs to support our technology initiatives.

Total other expense	$	(587)	$	(481)	$	(106)	(22.0)%

Total other expense remained fairly consistent. However, partially offsetting changes include increases in exchange losses and offering costs, partially offset by a gain on the re-measurement of our warrant liability. Our exchange gain was primarily attributable to changes in value of the Canadian dollar in relation to the U.S. dollar. Offering costs relate to the allocation of direct costs attributable to the warrants based on the relative fair value of warrants and common stock included in our recent registered direct offering. Changes in the fair value of our warrant liability are primarily driven by changes in our stock price. The decline in unconsolidated affiliate expenses pertains to the dissolution of a joint venture at the end of 2013.    

Income Tax Expense

As our effective tax rates are based on annualized expectations of income and losses, refer to the income tax expense discussion in the comparison of six months ended June 30, 2014 to six months ended June 30, 2013 for a more meaningful discussion.

Total revenues	$	25,053	100.0%	$	25,862	100.0%	$	(809)	(3.1)%

The decrease in revenues for our Heavy Duty Diesel Systems division was due to a $1.6 million increase in California sales under the Truck and Bus Rule and a $0.2 million increase in European fuel-borne catalyst sales, offset by a $1.5 million net decrease in the other 49 states and a $0.5 million decrease in European mining.

Excluding intercompany revenue, the $0.6 million decrease in revenues for our Catalyst division was due to a decrease in sales of primarily service parts to our non-Japanese OEM customers, while sales to our Japanese OEM customer remained consistent over the periods.

We eliminate intercompany sales by the Catalyst division to our Heavy Duty Diesel Systems division in consolidation.

       Selling, general and administrative expenses

The decrease in selling, general and administrative expenses was primarily due to a $0.3 million gain on the sale of a building at one of our foreign locations and $0.3 million of savings due to employee related costs.

Research and development expenses

The increase in research and development was primarily due to development work and outside testing related to new products and consultant costs to support our technology initiatives.

       Severance and other charges

The increase was due to $0.1 million in severance and lease exit costs related to our North American and United Kingdom locations and $0.1 million related to the settlement of a customer dispute. Additionally, we reached a legal settlement of all claims in March 2014 related to an administrative complaint originally filed against us by a former chief financial officer in 2010 whereby we have paid a lump sum amount of cash and shares of our common stock which had already been partially accrued in 2013. We recorded an additional $0.1 million related to the increase in fair value of our common stock.

Total other expense increased primarily due to a loss on the re-measurement of our warrant liability and exchange losses. Changes in the fair value of our warrant liability are primarily driven by changes in our stock price. Our exchange gain was primarily attributable to changes in value of the Canadian dollar in relation to the U.S. dollar. The decline in unconsolidated affiliate expenses pertains to the dissolution of a joint venture at the end of 2013.    

25

Income Tax Expense

We incurred income tax expense of $0.3 million in the six months ended June 30, 2014 compared to income tax benefit of $0.2 million in the six months ended June 30, 2013. The effective income tax rate was (5.7)% for the six months ended June 30, 2014, compared to 4.5% for the six months ended June 30, 2013. For interim income tax reporting, we estimate our annual effective tax rate and apply it to our year-to-date pre-tax loss. Tax jurisdictions with a projected or year-to-date loss for which a tax benefit cannot be realized are excluded from the annualized effective tax rate. The difference between our effective tax rate and the U.S. statutory tax rate is primarily related to the valuation allowance offsetting the deferred tax assets in both the U.S. and U.K. jurisdictions as well as to a foreign tax rate differential related to Sweden and Canada.

Liquidity and Capital Resources

Historically, the revenue that we have generated has not been sufficient to fund our operating requirements and debt servicing needs. Notably, we have suffered recurring losses since inception. As of June 30, 2014, we had an accumulated deficit of approximately $186.7 million compared to $181.7 million at December 31, 2013. We have also had negative cash flows from operations from inception. Our primary sources of liquidity in recent years have been asset sales, credit facilities and other borrowings and equity sales.

We had $8.6 million in cash at June 30, 2014 compared to $3.9 million at December 31, 2013. At June 30, 2014, $2.5 million of our cash was held by foreign subsidiaries in Canada, Sweden and the United Kingdom. We do not intend to repatriate any amount of this cash to the United States as it will be used to fund our subsidiaries’ operations. If we decide to repatriate unremitted foreign earnings in the future, it could have negative tax implications.  

We have a $7.5 million secured demand financing facility with FGI backed by our receivables and inventory that terminates on August 15, 2015 and may be extended at our option for additional one-year terms. However, FGI can cancel the facility at any time. For details regarding the FGI facility, see “—Description of Indebtedness” below and Note 8, “Debt.” At June 30, 2014, we had $3.4 million in borrowings outstanding with $4.1 million available under our FGI credit facility, subject to the availability of eligible accounts receivable and inventory balances for collateral. However, there is no guarantee that we will be able to borrow to the full limit of $7.5 million if FGI chooses not to finance a portion of our receivables or inventory.  

In addition, on May 15, 2012, we filed a shelf registration statement on Form S-3 with the SEC (the "Shelf Registration") which permits us to sell, from time to time, up to an aggregate of $50.0 million of various securities. However, we may not sell our securities in a primary offering pursuant to the Shelf Registration or any other registration statement on Form S-3 with a value exceeding one-third of our public float in any 12-month period (unless our public float rises to $75.0 million or more).The Shelf Registration is intended to provide us with additional flexibility to access capital markets for general corporate purposes, subject to market conditions and our capital needs.

On July 3, 2013, we completed a public offering under the Shelf Registration in which we sold 1,730,000 shares of common stock and warrants to purchase up to 865,000 shares of common stock and received net proceeds of $1.7 million after deducting discounts and commissions to the underwriter and offering expenses.

On March 21, 2014, we and Kanis S.A. entered into a letter agreement regarding our outstanding 8% subordinated convertible note due 2016 whereby Kanis S.A. has agreed not to accelerate the maturity of these notes prior to July 1, 2015.

On April 4, 2014, we completed a registered direct offering under the Shelf Registration in which we sold 2,030,000 shares of common stock and warrants to purchase 812,000 shares of common stock and received net proceeds of approximately $6.1 million after deducting placement agent fees and other offering expenses. For more discussion on this offering, see “—Recent Developments” and Note 9, “Stockholders’ Equity.”

We continue to pursue revenue generating opportunities relating to special government mandated retrofit programs in California and potentially others in various jurisdictions domestically and internationally. Opportunities such as these require cash investment in operating expenses and working capital such as inventory and receivables prior to realizing profits and cash from sales. Additionally, as previously discussed, we intend to pursue aggressive development of our materials science platform which will require cash investment.

26

Based on our current cash levels, the $6.1 million in proceeds from the April 2014 offering and expected cash flows from operations, we believe we have sufficient working capital to fund operations through the end of this year and into next year. However, there can be no assurances that we will be able to achieve projected levels of revenue and maintain access to sufficient working capital. If cash from operations is not sufficient for our working capital needs, we may be forced to seek additional financing in the form of funding from outside sources. However, there is no assurance that we will be able to raise additional funds or reduce our discretionary spending to a level sufficient for our working capital needs.

The following table summarizes our cash flows for the periods indicated.

	Six Months Ended June 30,

	2014		2013		$		%

Financing activities	$	8,545	$	(783)	$	9,328		1,191.3%

Cash used in operating activities

Our largest source of operating cash flows is cash collections from our customers following the sale of our products and services. Our primary uses of cash for operating activities are for purchasing inventory in support of the products that we sell, personnel related expenditures, facilities costs and payments for general operating matters. The increase in cash used in operating activities was primarily due to the settlement of certain litigation and increased tax obligations associated with a foreign location.

Cash provided by (used in) investing activities

Our cash flows from investing activities primarily relate to our recently dissolved joint venture with Pirelli, our Asian investment as well as capital expenditures to support our growth plans. The increase in cash provided by investing activities was primarily due to the sale of a building at one of our foreign locations and the return of most of our investment balance for our recently dissolved joint venture with Pirelli.

Cash provided by (used in) financing activities

Since inception, we have financed our net operating cash usage through a combination of financing activities such as issuance of equity or debt. The increase in cash provided by financing activities was largely due to a recent registered direct offering of common stock and warrants that provided net proceeds of $6.1 million. Other increases include proceeds from the exercise of equity instruments and an increase in net borrowing under our line of credit with FGI.

$3.0 million, 8% shareholder note due 2015		2,975		2,963
Total borrowings	$	11,014	$	9,807

We have a $7.5 million secured demand facility with FGI backed by our receivables and inventory (as amended, the “FGI Facility”). The FGI Facility expires on August 15, 2015 and may be extended at our option for additional one-year terms. However, FGI can cancel the facility at any time.

Under the FGI Facility, FGI can elect to purchase eligible accounts receivables from us and certain of our subsidiaries at up to 80% of the value of such receivables (retaining a 20% reserve). At FGI’s election, FGI may advance us up to 80% of the value of any purchased accounts receivable, subject to the $7.5 million limit. Reserves retained by FGI on any purchased receivable are expected to be refunded to us net of interest and fees on advances once the receivables are collected from customers. We may also borrow against eligible inventory up to the inventory sublimit as determined by FGI subject to the aggregate $7.5 million limit under the FGI Facility and certain other conditions. At June 30, 2014, the inventory sublimit was the lesser of $1.5 million or 50% of the aggregate purchase price paid for accounts receivable purchased under the FGI Facility. While the overall credit limit and the inventory sublimit were not changed, in the second quarter of 2014, borrowing against Honda inventory has been limited to $0.2 million by FGI due to their concerns about customer concentration.

27

The interest rate on advances or borrowings under the FGI Facility is the greater of (i) 6.50% per annum and (ii) 2.50% per annum above the prime rate, as defined in the FGI Facility, and was 6.50% at June 30, 2014 and December 31, 2013.

We were in compliance with the terms of the FGI Facility at June 30, 2014. However, there is no guarantee that we will be able to borrow the full limit of $7.5 million if FGI chooses not to finance a portion of our receivables or inventory.

For more information on our indebtedness, see Note 8.

Capital Expenditures

As of June 30, 2014, we had no commitments for capital expenditures and no material commitments are anticipated in the near future.

Off-Balance Sheet Arrangements

As of June 30, 2014 and December 31, 2013, we had no off-balance sheet arrangements.

Commitments and Contingencies

As of June 30, 2014, other than office leases, employment agreements with key executive officers and the obligation to fund our portion (5%) of the losses of our Asian investment, we had no material commitments other than the liabilities reflected in our unaudited condensed consolidated financial statement included elsewhere in this Quarterly Report on Form 10-Q.

Item 4.  Controls and Procedures

Disclosure Controls and Procedures

In evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective, at the reasonable assurance level, as of the end of the period covered by this report to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 (1) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (2) is accumulated and communicated to management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting during the period covered by this Quarterly Report on Form 10-Q.

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

2.  Summary of Significant Accounting Policies

a. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial reporting. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been reflected. The results reported in these unaudited condensed consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), but is not required for interim reporting purposes, has been condensed or omitted. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

b. Principles of Consolidation

The unaudited condensed consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation.

Investments in which the Company has at least a 20%, but not more than a 50% interest are generally accounted for under the equity method. Investment interests below 20% are generally accounted for under the cost method, except if the Company could exercise significant influence, the investment would be accounted for under the equity method. The Company’s judgment regarding the level of influence over each equity method investment includes considering key factors such as the Company’s ownership interest, representation on the Board of Directors, participation in policy-making decisions and material intercompany transactions. The Company includes its proportionate share of the net income or loss of equity-method investees in its unaudited condensed consolidated statements of comprehensive loss.

c. Use of Estimates

 The preparation of financial statements in conformity with U.S. GAAP requires management of the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. These estimates and assumptions are based on management’s best estimates and judgment. On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to impairment of goodwill and long-lived assets, stock-based compensation, the fair value of financial instruments including warrants, allowance for doubtful accounts, inventory valuation, taxes and contingent and accrued liabilities. The Company bases its estimates on historical experience and various other factors, including the current economic environment, which it believes to be reasonable under the circumstances. Estimates and assumptions are adjusted when facts and circumstances dictate. Actual results may differ from these estimates under different assumptions and conditions. Management believes that the estimates are reasonable.

d. Concentration of Risk

For the three and six months ended June 30, 2014, one automotive original equipment manufacturer (“OEM”) customer within the Catalyst segment accounted for 43% and 42%, respectively, of the Company’s revenues. This customer accounted for 41% of the Company’s revenues for the three and six months ended June 30, 2013. This customer accounted for 31% and 24% of the Company’s accounts receivable at June 30, 2014 and December 31, 2013, respectively. Another customer accounted for 10% of the Company’s accounts receivable at June 30, 2014. No other customers accounted for 10% or more of the Company’s revenues or accounts receivable for these periods.    

For the periods presented below, certain vendors accounted for 10% or more of the Company’s raw material purchases as follows:

B	19%	20%	24%	18%
C	10%	8%	10%	13%
D	12%	12%	13%	13%

Vendor A above is a catalyst supplier, vendors B and D above are substrate suppliers and vendor C is a rare earth materials supplier.

e. Net Loss per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of common shares and dilutive potential common shares. Dilutive potential common shares include employee stock options and restricted share units (“RSUs”) and warrants and debt that are convertible into the Company’s common stock.

Diluted net loss per share excludes certain dilutive potential common shares outstanding as their effect is anti-dilutive. Because the Company incurred net losses in the three and six months ended June 30, 2014 and 2013, the effect of potentially dilutive securities has been excluded in the computation of net loss per share and net loss from continuing operations per share as their impact would be anti-dilutive. Potentially dilutive common stock equivalents excluded were 2.3 million shares during each of the three months ended June 30 2014 and 2013. Potentially dilutive common stock equivalents excluded were 2.1 million and 2.2 million shares during the six months ended June 30 2014 and 2013, respectively. 

f. Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value in accordance with a hierarchy which requires an entity to maximize the use of observable inputs which reflect market data obtained from independent sources and minimize the use of unobservable inputs. There are three levels of inputs that may be used to measure fair value:

· Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities;

· Level 2: Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable including quoted prices for similar instruments in active markets and quoted prices for identical or similar instruments in markets that are not active; and

· Level 3: Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.

The Company records its liability-classified warrants at fair value in accordance with the fair value measurement framework. See Note 10 for further information on these liability-classified warrants. The valuation inputs hierarchy classification for the warrant liability measured at fair value on a recurring basis is summarized as follows (in thousands):

Warrant liability	Level 1	Level 2	Level 3
As of June 30, 2014	-	-	$	1,647
As of December 31, 2013	-	-	$	939

The following is a reconciliation of the warrant liability measured at fair value using Level 3 inputs (in thousands):

	Six Months Ended June 30,
	2014		2013
Balance at beginning of period	$	939	$	10
Issuance of common stock warrants		1,531		-
Exercise of common stock warrants		(2,505)		-
Remeasurement of common stock warrants		1,682		(6)
Balance at end of period	$	1,647	$	4

  g. Fair Value of Financial Instruments

Accounting Standards Codification (“ASC”) Topic 825, “Financial Instruments,” requires disclosure of the fair value of financial instruments for which the determination of fair value is practicable. The fair values of the Company’s cash, trade accounts receivable, prepaid expenses and other current assets, accounts payable and accrued expenses and other current liabilities approximate carrying values due to the short maturity of these instruments. The fair value of borrowings under the line of credit approximates their carrying value due to the variable interest rates. The fair value of shareholder notes payable calculated using level 3 inputs, using a Black-Scholes option-pricing model to value the debt’s conversion factor and a net present value model was $7.5 million at June 30, 2014 and December 31, 2013.

h. Reclassifications

Certain prior-period amounts have been reclassified to conform to the current period presentation. These changes had no impact on the previously reported consolidated results of operations or stockholders' equity.

i. Recent Accounting Pronouncements  

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. The Company does not expect the impact of the adoption of ASU 2014-08 to be material to its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)", and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements.

Accounting Policies, by Policy (Policies)

6 Months Ended

Jun. 30, 2014

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

a. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial reporting. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been reflected. The results reported in these unaudited condensed consolidated financial statements should not necessarily be taken as indicative of results that may be expected for the entire year. Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), but is not required for interim reporting purposes, has been condensed or omitted. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

Consolidation, Policy [Policy Text Block]

b. Principles of Consolidation

The unaudited condensed consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation.

Investments in which the Company has at least a 20%, but not more than a 50% interest are generally accounted for under the equity method. Investment interests below 20% are generally accounted for under the cost method, except if the Company could exercise significant influence, the investment would be accounted for under the equity method. The Company’s judgment regarding the level of influence over each equity method investment includes considering key factors such as the Company’s ownership interest, representation on the Board of Directors, participation in policy-making decisions and material intercompany transactions. The Company includes its proportionate share of the net income or loss of equity-method investees in its unaudited condensed consolidated statements of comprehensive loss.

Use of Estimates, Policy [Policy Text Block]

c. Use of Estimates

 The preparation of financial statements in conformity with U.S. GAAP requires management of the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. These estimates and assumptions are based on management’s best estimates and judgment. On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to impairment of goodwill and long-lived assets, stock-based compensation, the fair value of financial instruments including warrants, allowance for doubtful accounts, inventory valuation, taxes and contingent and accrued liabilities. The Company bases its estimates on historical experience and various other factors, including the current economic environment, which it believes to be reasonable under the circumstances. Estimates and assumptions are adjusted when facts and circumstances dictate. Actual results may differ from these estimates under different assumptions and conditions. Management believes that the estimates are reasonable.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

d. Concentration of Risk

For the three and six months ended June 30, 2014, one automotive original equipment manufacturer (“OEM”) customer within the Catalyst segment accounted for 43% and 42%, respectively, of the Company’s revenues. This customer accounted for 41% of the Company’s revenues for the three and six months ended June 30, 2013. This customer accounted for 31% and 24% of the Company’s accounts receivable at June 30, 2014 and December 31, 2013, respectively. Another customer accounted for 10% of the Company’s accounts receivable at June 30, 2014. No other customers accounted for 10% or more of the Company’s revenues or accounts receivable for these periods.    

For the periods presented below, certain vendors accounted for 10% or more of the Company’s raw material purchases as follows:

	Three Months Ended		Six Months Ended
	June 30,		June 30,
Vendor	2014	2013	2014	2013
A	7%	17%	17%	15%
B	19%	20%	24%	18%
C	10%	8%	10%	13%
D	12%	12%	13%	13%

Vendor A above is a catalyst supplier, vendors B and D above are substrate suppliers and vendor C is a rare earth materials supplier.

Earnings Per Share, Policy [Policy Text Block]

e. Net Loss per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of common shares and dilutive potential common shares. Dilutive potential common shares include employee stock options and restricted share units (“RSUs”) and warrants and debt that are convertible into the Company’s common stock.

Diluted net loss per share excludes certain dilutive potential common shares outstanding as their effect is anti-dilutive. Because the Company incurred net losses in the three and six months ended June 30, 2014 and 2013, the effect of potentially dilutive securities has been excluded in the computation of net loss per share and net loss from continuing operations per share as their impact would be anti-dilutive. Potentially dilutive common stock equivalents excluded were 2.3 million shares during each of the three months ended June 30 2014 and 2013. Potentially dilutive common stock equivalents excluded were 2.1 million and 2.2 million shares during the six months ended June 30 2014 and 2013, respectively.

Fair Value Measurement, Policy [Policy Text Block]

f. Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value in accordance with a hierarchy which requires an entity to maximize the use of observable inputs which reflect market data obtained from independent sources and minimize the use of unobservable inputs. There are three levels of inputs that may be used to measure fair value:

· Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities;

· Level 2: Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable including quoted prices for similar instruments in active markets and quoted prices for identical or similar instruments in markets that are not active; and

· Level 3: Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.

The Company records its liability-classified warrants at fair value in accordance with the fair value measurement framework. See Note 10 for further information on these liability-classified warrants. The valuation inputs hierarchy classification for the warrant liability measured at fair value on a recurring basis is summarized as follows (in thousands):

Warrant liability	Level 1	Level 2	Level 3
As of June 30, 2014	-	-	$	1,647
As of December 31, 2013	-	-	$	939

The following is a reconciliation of the warrant liability measured at fair value using Level 3 inputs (in thousands):

	Six Months Ended June 30,
	2014		2013
Balance at beginning of period	$	939	$	10
Issuance of common stock warrants		1,531		-
Exercise of common stock warrants		(2,505)		-
Remeasurement of common stock warrants		1,682		(6)
Balance at end of period	$	1,647	$	4

Fair Value of Financial Instruments, Policy [Policy Text Block]

g. Fair Value of Financial Instruments

Accounting Standards Codification (“ASC”) Topic 825, “Financial Instruments,” requires disclosure of the fair value of financial instruments for which the determination of fair value is practicable. The fair values of the Company’s cash, trade accounts receivable, prepaid expenses and other current assets, accounts payable and accrued expenses and other current liabilities approximate carrying values due to the short maturity of these instruments. The fair value of borrowings under the line of credit approximates their carrying value due to the variable interest rates. The fair value of shareholder notes payable calculated using level 3 inputs, using a Black-Scholes option-pricing model to value the debt’s conversion factor and a net present value model was $7.5 million at June 30, 2014 and December 31, 2013.

Reclassification, Policy [Policy Text Block]

h. Reclassifications

Certain prior-period amounts have been reclassified to conform to the current period presentation. These changes had no impact on the previously reported consolidated results of operations or stockholders' equity.

New Accounting Pronouncements, Policy [Policy Text Block]

i. Recent Accounting Pronouncements  

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning on or after December 15, 2014. Early adoption is permitted but only for disposals that have not been reported in financial statements previously issued. The Company does not expect the impact of the adoption of ASU 2014-08 to be material to its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)", and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements.

1. Organization

a. Description of Business

Clean Diesel Technologies, Inc. (“CDTi” or the “Company”) is a global manufacturer and distributor of heavy duty diesel and light duty vehicle emissions control systems and products to major automakers and retrofitters. CDTi’s business is driven by increasingly stringent global emission standards for internal combustion engines, which are major sources of a variety of harmful pollutants. The Company has operations in the United States, Canada, the United Kingdom, France, Japan and Sweden as well as an Asian investment.

b. Liquidity

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. Therefore, the consolidated financial statements contemplate the realization of assets and liquidation of liabilities in the ordinary course of business. The Company has suffered recurring losses and negative cash flows from operations since inception, resulting in an accumulated deficit of $186.7 million at June 30, 2014. The Company has funded its operations through equity sales, debt and bank borrowings.

The Company has a $7.5 million secured demand facility backed by its receivables and inventory with Faunus Group International, Inc. (“FGI”). At June 30, 2014, the Company had $3.4 million in borrowings outstanding under this facility with $4.1 million available, subject to the availability of eligible accounts receivable and inventory balances for collateral. There is no guarantee that the Company will be able to borrow to the full limit of $7.5 million if FGI chooses not to finance a portion of its receivables or inventory. Additionally, FGI can cancel the facility at any time.

On May 15, 2012, the Company filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission (“SEC”) (the “Shelf Registration”), which was declared effective by the SEC on May 21, 2012. The Shelf Registration permits the Company to sell, from time to time, up to an aggregate of $50.0 million of various securities, provided that the Company may not sell its securities in a primary offering pursuant to the Shelf Registration or any other registration statement on Form S-3 with a value exceeding one-third of its public float in any 12-month period (unless the Company’s public float rises to $75.0 million or more).

On July 3, 2013, the Company sold 1,730,000 units pursuant to the Shelf Registration for $1.25 per unit, with each unit consisting of one share of common stock and one half of a warrant to purchase one share of common stock with an exercise price of $1.25 per share. The Company received net proceeds of $1.7 million after deducting discounts and commissions to the underwriter and offering expenses. In the first quarter of 2014, warrant holders exercised an aggregate of 800,000 of the warrants issued in the offering at an exercise price of $1.25 per share for proceeds of $1.0 million.   

On March 21, 2014, the Company and Kanis S.A. entered into a letter agreement whereby Kanis S.A. agreed not to accelerate the maturity of the Company’s 8% subordinated convertible notes due 2016 prior to July 1, 2015. See Note 8 for additional information on these notes.

On April 4, 2014, the Company sold 2,030,000 units pursuant to the Shelf Registration for $3.40 per unit, with each unit consisting of one share of common stock and 0.4 of one warrant to purchase one share of common stock with an exercise price of $4.20 per share. The Company received net proceeds of $6.1 million after deducting placement agent fees and other offering expenses. See Note 9 for additional information.

At June 30, 2014, the Company had $8.6 million in cash. Based on the Company’s current cash levels, proceeds from the April 2014 offering and expected cash flows from operations, management believes that the Company will have access to sufficient working capital to fund operations through the end of this year and into next year. However, there can be no assurances that the Company will be able to achieve projected levels of revenue and maintain access to sufficient working capital. If cash from operations is not sufficient for the working capital needs of the Company, the Company may be forced to seek additional financing in the form of funding from outside sources. However, there is no assurance that the Company will be able to raise additional funds or reduce its discretionary spending to a level sufficient for its working capital needs.

12. Joint Venture

On February 19, 2013, the Company entered into a joint venture agreement (the “Joint Venture Agreement”) with Pirelli & C. Ambiente SpA (“Pirelli”) to form a joint venture entity, Eco Emission Enterprise Srl under the laws of Italy (the “Joint Venture”), through which the Company and Pirelli would jointly sell their emission control products in Europe and the Commonwealth of Independent States countries. The Joint Venture commenced operations in April 2013.

On November 8, 2013, as a result of slower than anticipated progress in achieving sales objectives initially established for the Joint Venture, the Company and Pirelli agreed to voluntarily dissolve the Joint Venture in accordance with the Joint Venture Agreement. The Joint Venture ceased operations on November 30, 2013 and commenced liquidation on December 9, 2013. The dissolution was finalized in April 2014. The majority of its investment balance of $0.1 million, included in other assets in the accompanying unaudited condensed consolidated balance sheets December 31, 2013, was received in April 2014, with a small balance to be collected following the receipt of VAT due from the Swedish and Italian governments. The Company has resumed its operations in Europe in a similar manner as conducted prior to the Joint Venture.

Legal Proceedings

On April 30, 2010, the Company received notice of an administrative complaint filed by its former chief financial officer. The complaint was filed with the Hartford, Connecticut office of the U.S. Department of Labor (“U.S. DOL”) under Section 806 of the Sarbanes-Oxley Act of 2002 (“SOX”) and alleged, among other things, that the Company’s termination of her employment on April 19, 2010 was retaliatory and due to her alleged protected activity associated with comments she made to the Company’s Board of Directors at their meeting on March 26, 2010. On June 14, 2010, the Company filed its response to the complaint denying the allegations and requesting a dismissal of the matter. On September 27, 2013, the U.S. DOL issued preliminary findings on the matter concluding there was reasonable cause to support the former employee’s claims and ordering the Company to pay damages in excess of $1.9 million and take certain other actions. On October 22, 2013, the Company filed its Objections and Request for Hearing with the U.S. DOL which triggered the appointment of an Administrative Law Judge (“ALJ”), and the scheduling of a hearing on the merits of the matter. Thereafter, the parties agreed to participate in a U.S. DOL mediation process on February 7, 2014. On March 13, 2014, the parties entered into a settlement agreement which provided for payment of a one-time lump sum amount of $0.4 million to the former employee, along with issuance of 75,000 shares of Company stock. The settlement was formally approved by the ALJ. As a result, there were mutual releases of all claims and a dismissal of the SOX complaint. The Company reserved $0.6 million at December 31, 2013, which included the lump sum amount, the market value of the common stock and accrued legal expenses incurred. The settlement was paid and stock issued in April 2014, and the Company recorded an additional $0.1 million related to the increase in the fair value of its common stock at the time of issuance.

On November 15, 2013, BP Products North America (“BP”) instituted claims against Johnson Matthey (“JM”) as the parent company of and purchaser of Applied Utility Systems, Inc. (“AUS”), a former subsidiary of the Company. On May 12, 2010, JM tendered to the Company a claim for indemnification under the Asset Purchase Agreement dated October 1, 2009, (the “Asset Purchase Agreement”), among JM, the Company and AUS. On June 11, 2013, BP, JM and the Company entered into a Settlement Agreement and Mutual Release pursuant to which they settled all claims. The settlement agreement had no material impact on the Company. Under the indemnification clauses of the Asset Purchase Agreement, the Company may be liable for legal expenses incurred by JM. These legal costs may be offset against funds withheld by JM from the acquisition of AUS.

In connection with the Asset Purchase Agreement, on October 1, 2009, JM presented the Company with an indemnification claim seeking recovery of the net amount of $0.9 million after offsetting the funds withheld by JM from the acquisition of AUS. These claims are for matters relating to various customer contracts that JM purchased, including the BP contract discussed above. The Company and JM have entered into discussions relating to the application of offsets and the validity of the claims presented. The Company has offered a settlement amount of $0.2 million and has reserved for this amount since the fourth quarter of 2013. Since the discussions are ongoing, the ultimate costs associated with this matter cannot be determined at this time.

In addition to the foregoing, the Company is involved in legal proceedings from time to time in the ordinary course of its business. Management does not believe that any of these claims and proceedings against it are likely to have, individually or in the aggregate, a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows. Accordingly, the Company cannot determine the final amount, if any, of its liability beyond the amount accrued in the unaudited condensed consolidated financial statements as of June 30, 2014, nor is it possible to estimate what litigation-related costs will be in the future.

Sales and Use Tax Audit

The Company is undergoing a sales and use tax audit by the State of California (the "State") on AUS for the period of 2007 through 2009. The audit has identified a project performed by the Company during that time period for which sales tax was not collected and remitted and for which the State asserts that proper documentation of resale may not have been obtained and that the Company owes sales tax of $1.4 million.The Company contends and believes that it received sufficient and proper documentation from its customer to support not collecting and remitting sales tax from that customer and is actively disputing the audit report with the State. On August 12, 2013, the Company appeared at an appeals conference with the State Board of Equalization ("BOE"). On July 21, 2014, the Company received a Decision and Recommendation (“D&R”) from the BOE. The D&R’s conclusion was that the basis for the calculation of the aforementioned $1.4 million tax due should be reduced from $12.2 million to $9.0 million with a commensurate reduction in the tax owed to the State. Regardless of this finding, the Company continues to believe that it will prevail in this matter, as it believes that the State did not adequately address the legal arguments related to the Company’s acceptance of the valid resale certificate from its customer. The Company has not agreed to these findings, and therefore, it will be appealing at a higher level at the BOE. Accordingly, no accrual has been recorded for this matter as the Company does not assess a loss as being probable. Should the Company not prevail in this matter, it will pursue reimbursement from the customer for all assessments from the State.

9. Stockholders’ Equity

Significant Changes in Stockholders’ Equity

During the six months ended June 30, 2014, additional paid-in capital increased by $9.0 million. $8.2 million of this increase is attributable to (i) $4.7 million in proceeds, net of costs, from a recent registered offering, (ii) $1.0 million in proceeds received from the exercise of warrants to purchase a total of 800,000 shares of the Company’s common stock and (iii) $2.5 million being the fair value of these warrants reclassified from liabilities. Refer to the April 2014 Offering discussion below and Note 10 for additional information.

Shelf Registration

On May 15, 2012, the Company filed a Shelf Registration which was declared effective by the SEC on May 21, 2012. The Shelf Registration permits the Company to sell, from time to time, up to an aggregate of $50.0 million of various securities, including common stock, preferred stock, warrants to purchase common stock or preferred stock and units consisting of one or more shares of common stock, shares of preferred stock, warrants, or any combination of such securities. However, the Company may not sell its securities in a primary offering pursuant to the Shelf Registration or any other registration statement on Form S-3 with a value exceeding one-third of its public float in any 12-month period (unless the Company’s public float rises to $75.0 million or more). The Shelf Registration is intended to provide the Company with additional flexibility to access capital markets for general corporate purposes, subject to market conditions and the Company's capital needs.

April 2014 Offering

On April 1, 2014, the Company entered into a placement agent agreement with Roth Capital Partners, LLC and Craig-Hallum Capital Group LLC related to the registered direct offering (the “Offering”) of an aggregate of 2,030,000 shares of the Company’s common stock together with warrants to purchase up to 812,000 shares of common stock. The Offering was made pursuant to the Company’s Shelf Registration discussed above. On April 4, 2014, the Company closed the Offering in which it sold 2,030,000 shares of common stock and warrants to purchase 812,000 shares of common stock. The shares of common stock and warrants were sold in units at $3.40 per unit, with each unit consisting of one share of common stock and 0.4 of one warrant to purchase one share of common stock at an exercise price of $4.20 per share.  

The Company received gross proceeds of $6.9 million and net proceeds of $6.1 million after deducting placement agent fees and other offering expenses. The Offering warrants are within the scope of ASC 815-40 and are required to be recorded as liabilities (see note 10). Accordingly, of the $6.1 million in net proceeds, $4.6 million was allocated to the common stock and included in additional paid-in capital and $1.5 million was allocated to the warrant liability based on the fair value of the warrants on the issuance date. Additionally, $0.2 million of the placement agent fees and other offering costs were allocated to the Offering warrants, based on the relative fair value of the Offering warrants and the common stock on the issuance date, and is included in other expense, net in the accompanying statement of comprehensive loss for the three and six months ended June 30, 2014. The Company intends to use the proceeds for general corporate purposes, which may include working capital, general and administrative expenses, capital expenditures and implementation of its strategic priorities. The Company may also use a portion of the net proceeds to acquire or invest in businesses, products and technologies that are complementary to its current business, although there are no present commitments or agreements for any such transactions.

Common Stock Purchase Agreement with Lincoln Park Capital ("LPC")

On October 7, 2011, the Company signed a Purchase Agreement with LPC, together with a Registration Rights Agreement, whereby LPC agreed to purchase up to $10.0 million of the Company’s common stock over a 30-month period ending April 24, 2014. This expired unused in April 2014.

Line of Credit with FGI

The Company has a $7.5 million secured demand facility with FGI backed by its receivables and inventory (as amended, the “FGI Facility”). The FGI Facility expires on August 15, 2015 and may be extended at the Company’s option for additional one-year terms. However, FGI can cancel the facility at any time.

Under the FGI Facility, FGI can elect to purchase eligible accounts receivables from the Company and certain of its subsidiaries at up to 80% of the value of such receivables (retaining a 20% reserve). Purchased receivables are subject to full recourse to the Company in the event of nonpayment by the customer. FGI becomes responsible for the servicing and administration of the accounts receivable purchased. The Company is not obligated to offer accounts in any month and FGI has the right to decline to purchase any accounts. At FGI’s election, FGI may advance the Company up to 80% of the value of any purchased accounts receivable, subject to the $7.5 million limit. Reserves retained by FGI on any purchased receivable are expected to be refunded to the Company net of interest and fees on advances once the receivables are collected from customers. The Company may also borrow against eligible inventory up to the inventory sublimit, as determined by FGI, subject to the aggregate $7.5 million limit under the FGI Facility and certain other conditions. At June 30, 2014, the inventory sublimit amount was the lesser of $1.5 million or 50% of the aggregate purchase price paid for accounts receivable purchased under the FGI facility. While the overall credit limit and the inventory sublimit were not changed, in the second quarter of 2014, borrowing against the Company's significant OEM customer's inventory has been limited to $0.2 million by FGI due to their concerns about customer concentration.

The interest rate on advances or borrowings under the FGI Facility is the greater of (i) 6.50% per annum and (ii) 2.50% per annum above the prime rate, as defined in the FGI Facility and was 6.50% at June 30, 2014 and December 31, 2013. Any advances or borrowings under the FGI Facility are due on demand. The Company also agreed to pay FGI collateral management fees of 0.30% per month on the face amount of eligible receivables as to which advances have been made and 0.38% per month on borrowings against inventory, if any. At any time outstanding advances or borrowings under the FGI Facility are less than $2.4 million, the Company agreed to pay FGI standby fees of (i) the interest rate on the difference between $2.4 million and the average outstanding amounts and (ii) 0.44% per month on 80% of the amount by which advances or borrowings are less than the agreed $2.4 million minimum.   

At June 30, 2014, the Company had $3.2 million of gross accounts receivable pledged to FGI as collateral for short-term debt in the amount of $2.6 million. At June 30, 2014, the Company also had $0.8 million in borrowings outstanding against eligible inventory. The Company was in compliance with the terms of the FGI Facility at June 30, 2014. However, there is no guarantee that the Company will be able to borrow to the full limit of $7.5 million if FGI chooses not to finance a portion of its receivables or inventory.

$1.5 Million, 8% Shareholder Note Due 2015

On December 30, 2010, the Company executed a Loan Commitment Letter with Kanis S.A., a shareholder of the Company, pursuant to which Kanis S.A. loaned the Company $1.5 million. The unsecured loan, as amended, bears interest on the unpaid principal at a rate of 8%, with interest only payable quarterly in arrears. In addition to principal and accrued interest, the Company is obligated to pay Kanis S.A. “Payment Premium” of $250,000 with $100,000 paid on June 30, 2013 and the remaining amount payable on the June 30, 2015 maturity date. There is no prepayment penalty.

$3.0 Million, 8% Subordinated Convertible Shareholder Notes Due 2016

On April 11, 2011, the Company entered into a Subordinated Convertible Notes Commitment Letter with Kanis S.A. that provides for the sale and issuance by the Company of 8% subordinated convertible notes (the “Notes”). As provided in the Commitment Letter, on May 6, 2011 Kanis S.A. purchased from the Company at par $3.0 million aggregate principal amount of the Notes, which bear interest at a rate of 8% per annum, payable quarterly in arrears.

The Notes have a stated maturity of five years from the date of issuance. The agreement, as amended, allows for the acceleration of the maturity of the Notes if: (i) the Company was in breach of the Notes or other agreements with Kanis S.A., or (ii) Kanis S.A. provided written notice, not less than 30 days prior to such date, that it elected to accelerate the maturity to a date not earlier than May 12, 2013. On March 21, 2014, the Company and Kanis S.A. entered into a letter agreement whereby Kanis S.A. agreed not to accelerate the maturity of these Notes prior to July 1, 2015. The Notes have been classified as noncurrent in the unaudited condensed consolidated balance sheets at June 30, 2014 and December 31, 2013.

The Notes also provide that the Company has the option to redeem the Notes at any time at a price equal to 100% of the face amount plus accrued and unpaid interest through the date of redemption. There is no prepayment penalty. The Notes are unsecured obligations of the Company and subordinated to existing and future secured indebtedness of the Company.  

As amended, the outstanding principal balance of the Notes, and accrued and unpaid interest are convertible, at the option of Kanis S.A., at any time upon written notice given not less than 75 calendar days prior to the date of conversion, into no more than 250,000 shares of the Company’s common stock at a conversion price of $4.00 per share.

$3.0 Million, 8% Shareholder Note Due 2015

On July 27, 2012, the Company executed a Loan Commitment Letter with Kanis S.A., pursuant to which the Company issued an unsecured promissory note in the principal amount of $3.0 million, which bears interest at 8% per annum, payable quarterly in arrears. The promissory note matures on July 27, 2015. There is no prepayment penalty or premium.

Warrants Disclosures [Abstract]

Warrants Disclosures [Text Block]

10.  Warrants

From time to time, the Company issues warrants to purchase its common stock. These warrants have been issued for consulting services, in connection with the Company’s issuance of debt and sales of its common stock.

Warrant activity is summarized as follows:  

		Weighted Average Exercise Price
				Range of Exercise Prices
	Shares
Outstanding at December 31, 2013	1,139,535	$	1.68	$1.25 - $10.40
Warrants issued	812,000	$	4.20	$4.20
Warrants exercised	(800,000)	$	1.25	$1.25
Outstanding at June 30, 2014	1,151,535	$	3.76	$1.25 - $10.40
Warrants exercisable at June 30, 2014	319,535	$	3.03	$1.25 - $10.40

Warrant Liability

The Company evaluates warrants on issuance and at each reporting date to determine proper classification as equity or as a liability. The Company’s warrant liability is carried at fair value and is classified as Level 3 in the fair value hierarchy because the warrants are valued based on unobservable inputs.

The Company determines the fair value of its warrant liability using the Black-Scholes option-pricing model unless the awards are subject to market conditions, in which case it uses a Monte Carlo simulation model, which utilizes multiple input variables to estimate the probability that market conditions will be achieved. These models are dependent on several variables such as the instrument’s expected term, expected strike price, expected risk-free interest rate over the expected term of the instrument, expected dividend yield rate over the expected term and the expected volatility. The expected strike price for warrants with full-ratchet down-round price protection is based on a weighted average probability analysis of the strike price changes expected during the term as a result of the full-ratchet down-round price protection. Due to the significant change in the Company following its business combination with Catalytic Solutions, Inc. (the “Merger”), CDTi’s pre-Merger historical price volatility was not considered representative of expected volatility going forward. Therefore, the Company has used an estimate based upon a weighted average of implied and historical volatility of a portfolio of peer companies and CDTi’s post-Merger historical volatility for the valuation of its warrants. The expected life is equal to the remaining contractual life of the warrants.

The Offering warrants require physical settlement by delivering registered shares. In addition, while the relevant warrant agreement does not require cash settlement if the Company fails to maintain registration of the warrant shares, it does not specifically preclude cash settlement. Accordingly, the Company’s agreement to deliver registered shares without express terms for settlement in the absence of continuous effective registration is presumed to create a liability to settle these warrants in cash, requiring liability classification. The assumptions used in the Black-Scholes option-pricing model to estimate the fair value of the warrant liability for these warrants are as follows:

	June 30, 2014		April 4, 2014
Warrants valued		812,000		812,000
CDTi stock price	$	2.71	$	2.95
Strike price	$	4.20	$	4.20
Expected volatility		84.5%		84.9%
Risk-free interest rate		1.7%		1.9%
Dividend yield		─		─
Expected life in years		5.3		5.5

The assumptions used in the Monte Carlo simulation model to estimate the fair value of the warrant liability for warrants with full-ratchet down-round protection are as follows:

	June 30, 2014		December 31, 2013
Warrants valued		159,000		959,000
CDTi stock price	$	2.71	$	1.51
Strike price	$	1.25	$	1.25
Expected volatility		76.5%		73.6%
Risk-free interest rate		1.3%		1.8%
Dividend yield		─		─
Expected life in years		4.0		4.5

The warrant liability, included in accrued expenses and other current liabilities in the accompanying unaudited condensed consolidated balance sheets, is re-measured at the end of each reporting period with changes in fair value recognized in other expense in the unaudited condensed consolidated statements of comprehensive loss. Upon the exercise of a warrant that is classified as a liability, the fair value of the warrant exercised is re-measured on the exercise date and reclassified from warrant liability to additional paid-in capital. The Company recorded other income of $0.4 million for the three months ended June 30, 2014 as a result of the change in fair value of the warrant liability, which was primarily due to a decrease in the Company’s stock price during this period. The Company recorded other expense of $1.7 million for the six months ended June 30, 2014 as a result of the change in fair value of the warrant liability which was primarily due to an increase in the Company’s stock price during the reporting period. During the six months ended June 30, 2014, as a result of the exercise of warrants to purchase 800,000 shares of the Company’s common stock, the warrant liability decreased $2.5 million, excluding the effects of remeasurement, with an offsetting increase to additional paid-in capital.

14. Segment Reporting and Geographic Information

The Company has two business division segments based on the products it delivers:

Heavy Duty Diesel Systems division — The Heavy Duty Diesel Systems division designs and manufactures verified exhaust emissions control solutions. This division offers a full range of products for the verified retrofit and non-retrofit OEM and aftermarket markets through its distributor/dealer network and direct sales. These products are used to reduce exhaust emissions created by on-road, off-road and stationary diesel and alternative fuel engines including propane and natural gas. The retrofit market in the U.S. is driven in particular by state and municipal environmental regulations and incentive funding for voluntary early compliance. The Heavy Duty Diesel Systems division derives significant revenues from retrofit with a portfolio of solutions verified by the California Air Resources Board and the United States Environmental Protection Agency.

Catalyst division — The Catalyst division produces catalysts to reduce emissions from gasoline, diesel and natural gas combustion engines that are offered for multiple markets and a wide range of applications. The Catalyst Division developed a family of unique high-performance catalysts, featuring inexpensive base-metals with low or even no platinum group metals, or PGMs, to provide increased catalytic function and value for technology-driven automotive industry customers. The Catalyst division’s technical and manufacturing competence in the light duty vehicle market is aimed at meeting auto makers’ most stringent requirements, and it has supplied over eleven million parts to light duty vehicle customers since 2001. The Catalyst division also provides catalyst formulations for the Company’s Heavy Duty Diesel Systems division. Intersegment revenues are based on market prices.

Corporate — Corporate includes cost for personnel, insurance and public company expenses such as legal, audit and taxes that are not allocated down to the operating divisions.
