Notes to Condensed Consolidated Financial Statements

(Unaudited)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

ZBB Energy Corporation (“ZBB,” “we,” “us,” “our” or the “Company”) develops, licenses, and manufactures innovative energy management systems solutions serving the utility, commercial and industrial building and off-grid markets.  ZBB was incorporated in Wisconsin in 1998 and is headquartered in Menomonee Falls, Wisconsin, USA with offices also located in Perth, Western Australia.

ZBB Energy develops and commercializes application solutions for advanced energy management systems critical to the transition from a “coal-centric economy” to one reliant on renewable energy sources.  These advanced systems directly connect wind and solar equipment to the grid and other systems that can form various levels of micro-grids as well as power quality regulation solutions.  ZBB Energy brings vital power control and energy storage solutions to problems caused by the incorporation of increasingly pervasive renewable energy generating assets that are part of the grid power transmission and distribution network used in commercial, industrial, and multi-tenant buildings.  The Company also develops and commercializes energy management systems for off-grid applications such as island or remote power.

The condensed consolidated financial statements include the accounts of the Company and those of its wholly-owned subsidiaries ZBB Energy Pty Ltd. (formerly known as ZBB Technologies, Ltd.) which has an advanced engineering and development facility in Perth, Australia, Century West PNL, LLC, and its sixty percent owned subsidiary ZBB PowerSav Holdings Limited located in Hong Kong which was formed in connection with the Company’s investment in a China joint venture.

Recent Developments

On April 17, 2015, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Solar Power, Inc., a California corporation (“SPI”) pursuant to which we will issue and sell to SPI for an aggregate purchase price of $33,390,000 a total of (i) 8,000,000 shares (the “Purchased Common Shares”) of common stock and (ii) 28,048 shares (the “Purchased Preferred Shares”) of Series C Convertible Preferred Stock.  The aggregate purchase price for the Purchased Common Shares was based on a purchase price per share of $0.6678 and the aggregate purchase price for the Purchased Preferred Shares was determined based on price of $0.6678 per common equivalent. Pursuant to the Purchase Agreement, the Company will issue to SPI a warrant to purchase 50,000,000 shares of Common Stock for an aggregate purchase price of $36,729,000 (the “Warrant”).

Pursuant to the Securities Purchase Agreement, the Company will enter into a supply agreement with SPI pursuant to which the Company will sell and SPI will purchase certain products and services offered by the Company from time to time, including certain energy management system solutions for solar projects (the “Supply Agreement”).

The Purchased Preferred Shares will be sold for $1,000 per share and are convertible at a conversion price of $0.6678, prepaid at closing of the transaction; provided, that (A) the first one-fourth of the Purchased Preferred Shares only become convertible upon the completion of five megawatts worth of solar projects in accordance with the Supply Agreement (the “Projects”), (B) the second one-fourth (the “Series C-2 Preferred Stock”) only become convertible upon the completion of 15 megawatts worth of Projects, (C) the third one-fourth (the “Series C-3 Preferred Stock”) only become convertible upon the completion of 25 megawatts worth of Projects, and (D) the last one-fourth only become convertible upon the completion of 40 megawatts worth of Projects. The Warrant represents the right to acquire 50,000,000 shares of Common Stock at an exercise price equal to $0.7346.  The Warrant only becomes exercisable upon the completion of 40 megawatts worth of Projects.

The closing of the Purchase Agreement is expected to take place following satisfaction of various closing conditions, including obtaining the approval of the Company’s shareholders.

Interim Financial Data

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements.  In the opinion of management, all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for fair presentation of the results of operations have been included.  Operating results for the three and nine month periods ended March 31, 2015 are not necessarily indicative of the results that might be expected for the year ending June 30, 2015.

The condensed consolidated balance sheet at June 30, 2014 has been derived from audited financial statements at that date, but does not include all of the information and disclosures required by US GAAP.  For a more complete discussion of accounting policies and certain other information, refer to the Company’s annual report filed on Form 10-K for the fiscal year ended June 30, 2014 filed with the Securities and Exchange Commission on September 29, 2014.

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly and majority-owned subsidiaries and have been prepared in accordance with US GAAP.  All significant intercompany accounts and transactions have been eliminated in consolidation.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, restricted cash on deposit, accounts receivable, a note receivable, accounts payable, and bank loans and notes payable.  The carrying amounts of the Company’s financial instruments approximate their respective fair values due to the relatively short-term nature of these instruments, except for the bank loans and notes payable.  The carrying amount of the bank loans and notes payable approximates fair value due to the interest rate and terms approximating those available to us for similar obligations.

The Company accounts for the fair value of financial instruments in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820.  Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level or pricing observability.  FASB ASC 820 describes a fair value hierarchy based on the following three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level 2 inputs are inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly, for similar assets or liabilities in active markets.

Level 3 inputs are unobservable inputs for the asset or liability.  As such, the prices or valuation techniques require inputs that are both significant to the fair value measurement and are unobservable.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less to be cash equivalents.  The Company maintains its cash deposits at financial institutions predominately in the United States, Australia, and Hong Kong.  The Company has not experienced any losses in such accounts.

Restricted Cash on Deposit

The Company had $60,178 and $69,901 in restricted cash on deposit as of March 31, 2015 and June 30, 2014, respectively, as collateral for certain credit arrangements.

8

Accounts Receivable

Credit is extended based on an evaluation of a customer’s financial condition.  Accounts receivable are stated at the amount the Company expects to collect from outstanding balances.  The Company records allowances for doubtful accounts based on customer-specific analysis and general matters such as current assessments of past due balances and economic conditions.  The Company writes off accounts receivable against the allowance when they become uncollectible.  Accounts receivable are stated net of an allowance for doubtful accounts of $10,878 as of March 31, 2015 and June 30, 2014.  The composition of accounts receivable by aging category is as follows as of:

	March 31, 2015		June 30, 2014
Current	$	54,396	$	902,545
30-60 days		-		-
60-90 days		1,396		-
Over 90 days		179,494		148,479
Total	$	235,286	$	1,051,024

Inventories

Inventories are stated at the lower of cost or market.  Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis.  The Company provides inventory write-downs based on excess and obsolete inventories determined primarily by future demand forecasts.  The write-down is measured as the difference between the cost of the inventory and market based upon assumptions about future demand and charged to the provision for inventory, which is a component of cost of sales.  At the point of the loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.

Note Receivable

The Company has one note receivable from an unrelated party.  The note matures on December 15, 2015 and is classified as “Note receivable” in the financial statements.  We regularly evaluate the financial condition of the borrower to determine if any reserve for uncollectible amount should be established.  To date, no such reserve is required.  See further discussion of the note receivable in Note 5.

Property, Plant and Equipment

Land, building, equipment, computers, furniture and fixtures are recorded at cost.  Maintenance, repairs and betterments are charged to expense as incurred.  Depreciation is provided for all plant and equipment on a straight-line basis over the estimated useful lives of the assets.  The estimated useful lives used for each class of depreciable asset are:

	Estimated Useful Lives
Manufacturing equipment	3 - 7 years
Office equipment	3 - 7 years
Building and improvements	7 - 40 years

The Company completed a review of the estimated useful lives of specific assets for the quarter ended March 31, 2015 and determined that there were no changes in the estimated useful lives of assets.

Impairment of Long-Lived Assets

In accordance with FASB ASC Topic 360, "Impairment or Disposal of Long-Lived Assets," the Company assesses potential impairments to its long-lived assets including property, plant, equipment and intangible assets when there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable.

9

If such an indication exists, the recoverable amount of the asset is compared to the asset’s carrying value.  Any excess of the asset’s carrying value over its recoverable amount is expensed in the statement of operations.  In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate.  Management has determined that there were no long-lived assets impaired as of March 31, 2015 and June 30, 2014.

Investment in Investee Company

Investee companies that are not consolidated, but over which the Company exercises significant influence, are accounted for under the equity method of accounting.  Whether or not the Company exercises significant influence with respect to an investee depends on an evaluation of several factors including, among others, representation on the investee company’s board of directors and ownership level, which is generally a 20% to 50% interest in the voting securities of the investee company.  Under the equity method of accounting, an investee company’s accounts are not reported in the Company’s condensed consolidated balance sheets and statements of operations; however, the Company’s share of the earnings or losses of the investee company is reflected in the caption ‘‘Equity in loss of investee company” in the condensed consolidated statements of operations.  The Company’s carrying value in an equity method investee company is reported in the caption ‘‘Investment in investee company’’ in the Company’s condensed consolidated balance sheets.

When the Company’s carrying value in an equity method investee company is reduced to zero, no further losses are recorded in the Company’s condensed consolidated financial statements unless the Company guaranteed obligations of the investee company or has committed additional funding.  When the investee company subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized.

Goodwill

Goodwill is recognized as the excess cost of an acquired entity over the net amount assigned to assets acquired and liabilities assumed.  Goodwill is not amortized but reviewed for impairment annually as of June 30 or more frequently if events or changes in circumstances indicate that its carrying value may be impaired.  These conditions could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit.

The first step of the impairment test requires the comparing of a reporting unit’s fair value to its carrying value.  If the carrying value is less than the fair value, no impairment exists and the second step is not performed.  If the carrying value is higher than the fair value, there is an indication that impairment may exist and the second step must be performed to compute the amount of the impairment.  In the second step, the impairment is computed by estimating the fair values of all recognized and unrecognized assets and liabilities of the reporting unit and comparing the implied fair value of reporting unit goodwill with the carrying amount of that unit’s goodwill.  The Company determined fair value as evidenced by market capitalization, and concluded that there was no need for an impairment charge as of March 31, 2015 and June 30, 2014.

Accrued Expenses

Accrued expenses consist of the Company’s present obligations related to various expenses incurred during the period and includes a reserve for estimated contract losses, other accrued expenses, and warranty obligations.  Included in accrued expenses as of March 31, 2015 is a reserve of approximately $1.1 million for a product upgrade initiative established in the fourth quarter of fiscal 2014.

Subsequent to commercialization, installation and commissioning of units in the field, the Company garnered meaningful insights that have resulted in system design modifications and other general upgrades that have improved the performance, efficiency, and reliability of its systems.  In the interest of enhancing customer satisfaction, the Company launched the product upgrade initiative to implement these improvements at certain locations of its installed base over fiscal years 2015 and 2016.

10

Warranty Obligations

The Company typically warrants its products for twelve months after installation or eighteen months after date of shipment, whichever occurs first.  Warranty costs are provided for estimated claims and charged to cost of product sales as revenue is recognized.  Warranty obligations are also evaluated quarterly to determine a reasonable estimate for the replacement of potentially defective materials of all energy storage systems that have been shipped to customers.

While the Company actively engages in monitoring and improving its evolving battery and production technologies, there is only a limited product history and relatively short time frame available to test and evaluate the rate of product failure.  Should actual product failure rates differ from the Company’s estimates, revisions are made to the estimated rate of product failures and resulting changes to the liability for warranty obligations.  In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise.

As of March 31, 2015 and June 30, 2014, included in the Company’s accrued expenses were $395,059 and $731,910, respectively, related to warranty obligations.  The following is a summary of accrued warranty activity:

	Nine Months and Year Ended
	March 31, 2015			June 30, 2014
Beginning balance	$	731,910		$	479,873
Accruals for warranties during the period		151,644			741,412
Settlements during the period		(288,334	)		(673,588	)
Adjustments relating to preexisting warranties		(200,161	)		184,213
Ending balance	$	395,059		$	731,910

Revenue Recognition

Revenues are recognized when persuasive evidence of a contractual arrangement exits, delivery has occurred or services have been rendered, the seller’s price to buyer is fixed and determinable, and collectability is reasonably assured.  The portion of revenue related to installation and final acceptance, is deferred until such installation and final customer acceptance are completed.

From time to time, the Company may enter into separate agreements at or near the same time with the same customer.  The Company evaluates such agreements to determine whether they should be accounted for individually as distinct arrangements or whether the separate agreements are, in substance, a single multiple element arrangement.  The Company evaluates whether the negotiations are conducted jointly as part of a single negotiation, whether the deliverables are interrelated or interdependent, whether the fees in one arrangement are tied to performance in another arrangement, and whether elements in one arrangement are essential to another arrangement.  The Company’s evaluation involves significant judgment to determine whether a group of agreements might be so closely related that they are, in effect, part of a single arrangement.

Our collaboration agreements typically involve multiple elements or deliverables, including upfront fees, contract research and development, milestone payments, technology licenses or options to obtain technology licenses, and royalties.  For these arrangements, revenues are recognized in accordance with FASB ASC 605-25,“Revenue Recognition – Multiple Element Arrangements.”  The Company’s revenues associated with multiple element contracts is based on the selling price hierarchy, which utilizes vendor-specific objective evidence (“VSOE”) when available, third-party evidence (“TPE”) if VSOE is not available, and if neither is available then the best estimate of the selling price is used.  The Company utilizes best estimate for its multiple deliverable transactions as VSOE and TPE do not exist.  To be considered a separate element, the product or service in question must represent a separate unit under SEC Staff Accounting Bulletin 104, and fulfill the following criteria: the delivered item(s) has value to the customer on a standalone basis; there is objective and reliable evidence of the fair value of the undelivered item(s); and if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control. For arrangements containing multiple elements, revenue from time and materials based service arrangements is recognized as the service is performed.  Revenue relating to undelivered elements is deferred at the estimated fair value until delivery of the deferred elements.  If the arrangement does not meet all criteria above, the entire amount of the transaction is deferred until all elements are delivered.

11

The portion of revenue related to engineering and development is recognized ratably upon delivery of the goods or services pertaining to the underlying contractual arrangement or revenue is recognized as certain activities are performed by the Company over the estimated performance period.

Revenues from government funded research and development contracts are recognized proportionally as costs are incurred and compared to the estimated total research and development costs for each contract.  In many cases, the Company is reimbursed only a portion of the costs incurred or to be incurred on the contract.  Government funded research and development contracts are generally multi-year, cost-reimbursement and/or cost-share type contracts.  The Company is generally reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract.

The Company charges shipping and handling fees when products are shipped or delivered to a customer, and includes such amounts in product revenues and shipping costs in cost of sales.  The Company reports its revenues net of estimated returns and allowances.

Total revenues of $584,817 and $1,450,332 were recognized for the three and nine months ended March 31, 2015, respectively.  Revenues for the three months ended March 31, 2015 were comprised of two significant customers (88% of total revenue) and revenues for the nine months ended March 31, 2015 were comprised of two significant customers (79% of total revenue).  Total revenues of $4,572,318 and $6,602,896 were recognized for the three and nine months ended March 31, 2014, respectively.  Revenues for the three months ended March 31, 2014 consisted of one significant customer (83% of total revenue) and revenues for the nine months ended March 31, 2014 were comprised of two significant customers (84% of total revenue).

Engineering, Development, and License Revenues

We assess whether a substantive milestone exists at the inception of our agreements.  In evaluating if a milestone is substantive we consider whether:

· Substantive uncertainty exists as to the achievement of the milestone event at the inception of the arrangement;

· The achievement of the milestone involves substantive effort and can only be achieved based in whole or in part on our performance or the occurrence of a specific outcome resulting from our performance;

· The amount of the milestone payment appears reasonable either in relation to the effort expended or the enhancement of the value of the delivered item(s);

· There is no future performance required to earn the milestone; and

· The consideration is reasonable relative to all deliverables and payment terms in the arrangement.

If any of these conditions are not met, we do not consider the milestone to be substantive and we defer recognition of the milestone payment and recognize it as revenue over the estimated period of performance, if any.

On December 13, 2011, the Company entered into a joint development and license agreement with a global technology company to jointly develop flow batteries.  The objective of the joint development agreement was to develop low cost, high energy density grid scale flow battery stacks and systems that could lead to a significant cost reduction for grid level storage.  The Company recognized revenue under this agreement upon achievement of certain performance milestones.  The Company recognized $0 of revenue under this agreement for the three and nine months ended March 31, 2015 and $0 and $200,000 for the three and nine months ended March 31, 2014, respectively.

On April 8, 2011, the Company entered into a Collaboration Agreement (the “Collaboration Agreement”) with Honam Petrochemical Corporation, now known as Lotte Chemical Corporation (“Lotte”), pursuant to which the Company and Lotte collaborated on the technical development of the Company’s third generation Zinc Bromide flow battery module (the “Version 3 Battery Module”) and Lotte received a fully paid-up, exclusive and royalty-free license to sell and manufacture the Version 3 Battery Module in South Korea and a non-exclusive royalty-bearing license to sell the Version 3 Battery Module in Japan, Thailand, Taiwan, Malaysia, Vietnam and Singapore.

12

On December 16, 2013, the Company and Lotte entered into a Research and Development Agreement (the “R&D Agreement”) pursuant to which the Company has agreed to develop and provide to Lotte a Zinc Bromide chemical flow battery system, including a Zinc Bromide chemical flow battery module and related software (the “Product”), on the terms and conditions set forth in the R&D Agreement (the “Project”).  The Project is scheduled to continue until December 16, 2015, unless extended by the mutual agreement of the Company and Lotte.  Subject to the satisfaction of certain specified milestones, Lotte is required to make payments to the Company under the R&D Agreement totaling $3,000,000 over the term of the Project.  ZBB recognizes revenue based upon a Performance Based Method pursuant to the model described in FASB ASC 980-605-25, where revenue is recognized based on the lesser of the amount of nonrefundable cash received or the amounts due based on the proportional amount of the total effort expected to be expended on the contract that has been provided to date, as substantial doubt that the milestones will be achieved does not exist.  The Company recognized $297,173 and $483,650 of revenue under this agreement for the three and nine months ended March 31, 2015, respectively and $750,000 of revenue under this agreement for the three and nine months ended March 31, 2014.

Additionally, on December 16, 2013, the Company and Lotte entered into an Amended License Agreement (the “Amended License”).  Pursuant to the Amended License Agreement, the Company granted to Lotte, (1) an exclusive and royalty-free limited license in South Korea to use the Company’s Zinc Bromide flow battery module, Zinc Bromide flow battery stack and the technical information and know how related to the intellectual property arising from the Project (collectively, the “Technology”) to manufacture or sell a Zinc Bromide flow battery (the “Lotte Product”) in South Korea and (2) a non-exclusive (a) royalty-free limited license for Lotte and its affiliates to use the Technology internally in all locations other than China and South Korea to manufacture the Lotte Product and (b) royalty-bearing limited license to sell the Lotte Product in all locations other than China, the United States and South Korea. Lotte is required to pay the Company a total license fee of $3,000,000 under the Amended License Agreement plus up to an additional $1,000,000 if certain specific milestones are successfully achieved.  In addition, Lotte is required to make ongoing royalty payments to the Company equal to a single digit percentage of Lotte’s sales of the Lotte Product outside of South Korea until December 31, 2019.  The license fees are subject to a 16.5% non-refundable South Korea withholding tax.

Overall since the agreement date, through March 31, 2015 there were $5,250,000 of payments received and $4,608,650 of revenue recognized under the Lotte agreements.

The Company recognized $297,173 in engineering and development revenues for the three months ended March 31, 2015 and $499,170 for the nine months ended March 31, 2015.  The Company recognized $750,000 and $950,000 for the nine months ended March 31, 2014 related to collaborative agreements.  Engineering and development costs related to the collaboration agreements totaled $33,078 and $202,223 for the three and nine months ended March 31, 2015.  Engineering and development costs related to the collaboration agreements totaled $65,560 and $109,196 for the three and nine months ended March 31, 2014, respectively.

As of March 31, 2015 and March 31, 2014, the Company had no unbilled amounts from engineering and development contracts in process.  The Company had received $673,030 and $0 in customer payments for engineering and development contracts, representing deposits in advance of performance of the contracted work, as of March 31, 2015, and June 30, 2014, respectively.  These amounts are included as a component of customer deposits in the condensed consolidated balance sheets.

Advanced Engineering and Development Expenses

In accordance with FASB ASC Topic 730, “Research and Development,” the Company expenses advanced engineering and development costs as incurred.  These costs consist primarily of materials, labor, and allocable indirect costs incurred to design, build, and test prototype units, as well as the development of manufacturing processes for these units.  Advanced engineering and development costs also include consulting fees and other costs.

13

To the extent these costs are separately identifiable, incurred and funded by advanced engineering and development type agreements with outside parties, they are shown separately on the condensed consolidated statements of operations as a “Cost of engineering and development.”

Stock-Based Compensation

The Company measures all “Share-Based Payments," including grants of stock options, restricted shares and restricted stock units to be recognized in its condensed consolidated statement of operations based on their fair values on the grant date, which is consistent with FASB ASC Topic 718, “Stock Compensation,” guidelines.

Accordingly, the Company measures share-based compensation cost for all share-based awards at the fair value on the grant date and recognition of share-based compensation over the service period for awards that are expected to vest.  The fair value of stock options is determined based on the number of shares granted and the price of the shares at grant, and calculated based on the Black-Scholes valuation model.

The Company compensates its outside directors primarily with restricted stock units (“RSUs”) rather than cash.  The grant date fair value of the restricted stock unit awards is determined using the closing stock price of the Company’s common stock on the day prior to the date of the grant, with the compensation expense amortized over the vesting period of restricted stock unit awards, net of estimated forfeitures.

The Company only recognizes expense to its statements of operations for those options or shares that are expected ultimately to vest, using two attribution methods to record expense, the straight-line method for grants with only service-based vesting or the graded-vesting method, which considers each performance period, for all other awards.  See further discussion of stock-based compensation in Note 9.

Advertising Expense

Advertising costs of $3,284 and $16,245 for the three months ended March 31, 2015 and March 31, 2014, respectively, and advertising costs of $36,546 and $49,859 for the nine months ended March 31, 2015 and March 31, 2014, respectively, were charged to selling, general, and administrative expenses as incurred.

Income Taxes

The Company records deferred income taxes in accordance with FASB ASC Topic 740, “Accounting for Income Taxes.”  FASB ASC Topic 740 requires recognition of deferred income tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted tax rates in effect for the year in which the differences are expected to reverse.  The Company establishes a valuation allowance when necessary to reduce deferred income tax assets to the amount expected to be realized.  There were no net deferred income tax assets recorded as of March 31, 2015 and June 30, 2014.

The Company applies a more-likely-than-not recognition threshold for all tax uncertainties as required under FASB ASC Topic 740, which only allows the recognition of those tax benefits that have a greater than fifty percent likelihood of being sustained upon examination by the taxing authorities.

The Company’s U.S. Federal income tax returns for the years ended June 30, 2011 through June 30, 2014 and the Company’s Wisconsin and Australian income tax returns for the years ended June 30, 2010 through June 30, 2014 are subject to examination by taxing authorities.  As of March 31, 2015, there were no examinations in progress.

Foreign Currency

The Company uses the United States dollar as its functional and reporting currency, while the Australian dollar and Hong Kong dollar are the functional currencies of its foreign subsidiaries.  Assets and liabilities of the Company’s foreign subsidiaries are translated into United States dollars at exchange rates that are in effect at the balance sheet date while equity accounts are translated at historical exchange rates.  Income and expense items are translated at average exchange rates which were applicable during the reporting period.  Translation adjustments are accumulated in accumulated other comprehensive loss as a separate component of equity in the condensed consolidated balance sheets.

14

Loss per Share

The Company follows the FASB ASC Topic 260, “Earnings per Share,” provisions which require the reporting of both basic and diluted earnings (loss) per share.  Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period.  Diluted earnings (net loss) per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.  In accordance with the FASB ASC Topic 260, any anti-dilutive effects on net income (loss) per share are excluded.  For the nine months ended March 31, 2015 and March 31, 2014 there were 9,809,404 and 9,474,075 shares of common stock underlying convertible preferred stock, options, restricted stock units and warrants that are excluded, respectively.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable.

The Company maintains significant cash deposits primarily with two financial institutions. The Company has not previously experienced any losses on such deposits.  Additionally, the Company performs periodic evaluations of the relative credit ratings of these institutions as part of its banking strategy.

Concentrations of credit risk with respect to accounts receivable are limited due to accelerated payment terms in current customer contracts and creditworthiness of the current customer base.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions.  These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period.  It is reasonably possible that the estimates we have made may change in the near future.  Significant estimates underlying the accompanying condensed consolidated financial statements include those related to:

· the timing of revenue recognition;

· the allowance for doubtful accounts;

· provisions for excess and obsolete inventory;

· the lives and recoverability of property, plant and equipment and other long-lived assets, including goodwill;

· contract costs, losses, and reserves;

· warranty obligations;

· income tax valuation allowances;

· stock-based compensation; and

· valuation of warrants.

Reclassifications

Certain amounts previously reported have been reclassified to conform to the current presentation.

Segment Information

The Company has determined that it operates as one reportable segment.

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date.  Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

In February 2015, the FASB issued ASU 2015-02 – Consolidation (Topic 810): Amendments to the Consolidation Analysis.  The amendments are intended to improve certain areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures.  The amendments simplify reporting requirements by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public companies in several industries that typically make use of limited partnerships or VIEs.  The amendment is effective for fiscal years beginning after December 31, 2015.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In January 2015, the FASB issued ASU 2015-01 – Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.  The amendment was issued to reduce complexity in the accounting standards by eliminating the concept of extraordinary items from US GAAP.  The amendment is effective for annual periods ending after December 15, 2015.  The change may be applied prospectively or retrospectively to all prior periods presented in the financial statements.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In August 2014, the FASB issued ASU 2014-15 – Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40).  The update requires management to perform a going concern assessment if there is substantial doubt about an entity’s ability to continue as a going concern within one year of the financial statement issuance date.  Under the new standard, the definition of substantial doubt incorporates a likeliness threshold of “probable” that is consistent with the current use of the term defined in US GAAP for loss contingencies (Topic 450 – Contingencies).  Management will need to consider conditions that are known and reasonably knowable at the financial statement issuance date and determine whether the entity will be able to meet its obligations within the one-year period.  Additional disclosures are required if it is probable that the entity will be unable to meet its current obligations.  The amendments in this ASU will be effective for annual periods ending after December 15, 2016.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In June 2014, the FASB issued ASU 2014-12 - Compensation – Stock Compensation (Topic 718).  The amendments require that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting and, accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award.  Compensation expense should be recognized in the period in which it becomes probable that the performance target will be achieved.  ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015.  The Company is required to adopt this standard beginning July 1, 2016.  ASU 2014-12 does not contain any new disclosure requirements.  The Company does not expect the adoption of ASU 2014-12 to have a material effect on our financial position, results of operations or cash flows.

16

In May 2014, the FASB issued ASU 2014-09 – Revenue from Contracts with Customers (Topic 606).  The amendments outline a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersede most current revenue recognition guidance, including industry-specific guidance.  The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  In applying the revenue model to contracts within its scope, an entity identifies the contract(s) with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to the performance obligations in the contract and recognizes revenue when the entity satisfies a performance obligation.  ASU 2014-09, which includes additional disclosure requirements regarding revenue, cash flows and obligations related to contracts with customers, will be effective for annual reporting periods beginning after December 15, 2016.  Early adoption is not permitted.  The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment.  The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations upon adoption.

In April 2014, the FASB issued ASU 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.  The update changes the requirements for reporting discontinued operations in Subtopic 205-20.  To be classified as a discontinued operation, the disposal of a component or group of components must represent a strategic shift that has, or will have, a major effect on an entity’s operations and financial results.  Examples include a disposal of a major geographic area, a major line of business or a major equity method investment.  The amendments in this ASU are effective prospectively for reporting periods beginning on or after December 15, 2014, with early adoption permitted.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU 2013-11 – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, similar tax loss, or a tax credit carryforward.  To the extent the tax benefit is not available at the reporting date under the governing tax law or if the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented as a liability and not combined with deferred tax assets.  ASU 2013-11 is effective for annual periods, and interim periods within those years, beginning after December 15, 2013.  The amendments are to be applied to all unrecognized tax benefits that exist as of the effective date and may be applied retrospectively to each prior reporting period presented.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In April 2013, the FASB issued ASU 2013-07 – Presentation of Financial Statements (Topic 205) – Liquidation Basis of Accounting.  The amendments require an entity to prepare its financial statements using the liquidation basis of accounting when liquidation is imminent.  Liquidation is imminent when the likelihood is remote that the entity will return from liquidation and either (a) a plan for liquidation is approved by the person or persons with the authority to make such a plan effective and the likelihood is remote that the execution of the plan will be blocked by other parties or (b) a plan for liquidation is being imposed by other forces (for example, involuntary bankruptcy).  If a plan for liquidation was specified in the entity’s governing documents from the entity’s inception (for example, limited-life entities), the entity should apply the liquidation basis of accounting only if the approved plan for liquidation differs from the plan for liquidation that was specified at the entity’s inception.  The amendments require financial statements prepared using the liquidation basis of accounting to present relevant information about an entity’s expected resources in liquidation by measuring and presenting assets at the amount of the expected cash proceeds from liquidation.  The entity should include in its presentation of assets any items it had not previously recognized under US GAAP but that it expects to either sell in liquidation or use in settling liabilities (for example, trademarks).  The amendments are effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein.  Entities should apply the requirements prospectively from the day that liquidation becomes imminent.  Early adoption was permitted.  The adoption did not have an impact on the Company’s consolidated financial statements in its present condition.

17

In March 2013, the FASB issued ASU 2013-05 – Foreign Currency Matters (Topic 830) – Parent’s Accounting for the Cumulative Translation Adjustment upon derecognition of Certain Subsidiaries or Group of Assets within a Foreign Entity or of an Investment in a Foreign Entity.  These amendments provide guidance on releasing cumulative translation adjustments when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or a group of assets that is a non-profit activity or a business within a foreign entity.  In addition, these amendments provide guidance on the release of cumulative translation adjustments in partial sales of equity method investments and in step acquisitions.  The amendments are effective for fiscal years and interim reporting periods within those years, beginning after December 15, 2013.  The amendments should be applied prospectively to derecognition events occurring after the effective date.  Prior periods should not be adjusted.  Early adoption was permitted.  If an entity elects to early adopt the amendments, it should apply them as of the beginning of the entity’s fiscal year of adoption.  The Company was required to adopt this standard beginning July 1, 2014.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU 2013-04 – Liabilities (Topic 405) – Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date.  These amendments provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in US GAAP.  Examples of obligations within this guidance are debt arrangements, other contractual obligations, and settled litigation and judicial rulings.  The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013.  These amendments shall be applied retrospectively to all prior periods presented for those obligations within the scope of this Subtopic that exist at the beginning of an entity’s fiscal year of adoption.  Early adoption was permitted.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

NOTE 2 - CHINA JOINT VENTURE

On August 30, 2011, the Company entered into agreements providing for establishment of a joint venture to develop, produce, sell, distribute and service advanced storage batteries and power electronics in China (the “Joint Venture”).  Joint Venture partners include ZBB PowerSav Holdings Limited (“Holdco”), AnHui XinLong Electrical Co. and Wuhu Huarui Power Transmission and Transformation Engineering Co.  The Joint Venture was established upon receipt of certain governmental approvals from China which were received in November 2011.

The Joint Venture operates through a jointly-owned Chinese company located in Wuhu City, Anhui Province named Anhui Meineng Store Energy Co., Ltd. (“Meineng Energy”).  Meineng Energy intends to initially assemble and ultimately manufacture the Company’s products for sale in the power management industry on an exclusive basis in mainland China and on a non-exclusive basis in Hong Kong and Taiwan.

The Company’s President and Chief Operating Officer (“President and COO”) has served as the Chief Executive Officer of Meineng Energy since December 2011.  The President and COO owns an indirect 6% equity interest in Meineng Energy.

In connection with the Joint Venture, on August 30, 2011 the Company and certain of its subsidiaries entered into the following agreements:

· Joint Venture Agreement of Anhui Meineng Store Energy Co., Ltd. (the “China JV Agreement”) by and between ZBB PowerSav Holdings Limited, a Hong Kong limited liability company (“Holdco”), and Anhui Xinrui Investment Co., Ltd, a Chinese limited liability company; and

· Limited Liability Company Agreement of ZBB PowerSav Holdings Limited by and between ZBB Cayman Corporation and PowerSav New Energy Holdings Limited (the “Holdco Agreement”).

18

In connection with the Joint Venture, upon establishment of Meineng Energy, the Company and certain of its subsidiaries entered into the following agreements:

· Management Services Agreement by and between Meineng Energy and Holdco (the “Management Services Agreement”);

· License Agreement by and between Holdco and Meineng Energy (the “License Agreement”); and

· Research and Development Agreement by and between the Company and Meineng Energy (the “Research and Development Agreement”).

Pursuant to the China JV Agreement, Meineng Energy was capitalized with approximately $13.6 million of equity capital.  The Company’s only capital contributions to the Joint Venture were the contribution of technology to Meineng Energy via the License Agreement and $200,000 in cash.  The Company’s indirect interest in Meineng Energy equaled approximately 33%.  On August 12, 2014, Meineng Energy received a cash investment of 20,000,000 RMB (approximately $3.2 million) from Wuhu Fuhai-Haoyan Venture Investment, L.P., a branch of Shenzhen Oriental Fortune Capital Co., Ltd., for a post-closing equity position of 8%.  Required governmental approval was obtained in October 2014.  This investment capital will be used to fund ongoing operations and development of the China market, and provided Meineng Energy a 250,000,000 RMB (approximately $42 million) post-closing valuation.  Following this investment, the Company’s indirect investment in Meineng Energy equals approximately 30%.  The Company’s indirect gain as a result of the investment was $775,537, which is net of the gain attributable to the noncontrolling interest of $481,870.

The Company’s investment in Meineng Energy was made through Holdco.  Pursuant to the Holdco Agreement, the Company contributed to Holdco technology via a license agreement with an agreed upon value of approximately $4.1 million and $200,000 in cash in exchange for a 60% equity interest and PowerSav agreed to contribute to Holdco $3.3 million in cash in exchange for a 40% equity interest.  The initial capital contributions (consisting of the Company’s technology contribution and one half of required cash contributions) were made in December 2011.  The subsequent capital contributions (consisting of one half of the required cash contribution) were made on May 16, 2012.  For financial reporting purposes, Holdco’s assets and liabilities are consolidated with those of the Company and PowerSav’s 40% interest in Holdco is included in the Company’s condensed consolidated financial statements as a noncontrolling interest.

The Company’s basis in the technology contributed to Holdco is $0 due to US GAAP requirements related to research and development expenditures.  The difference of approximately $4.1 million in the Company’s basis in this technology and the valuation of the technology by Meineng Energy is accounted for by the Company through the elimination of the amortization expense recognized by Meineng Energy related to the technology.

The Company has the right to appoint a majority of the members of the Board of Directors of Hong Kong Holdco and Hong Kong Holdco has the right to appoint a majority of the members of the Board of Directors of Meineng Energy.

Pursuant to the Management Services Agreement, Holdco will provide certain management services to Meineng Energy in exchange for a management services fee equal to five percent of Meineng Energy’s net sales for the five year period beginning on the first day of the first quarter in which the JV Company achieves operational breakeven results and three percent of Meineng Energy’s net sales for the subsequent three years, provided the payment of such fees will terminate upon Meineng Energy completing an initial public offering on a nationally recognized securities exchange.  To date, no management service fee revenues have been recognized by Holdco.

Pursuant to the Amended License Agreement dated July 1, 2014, Holdco granted to Meineng Energy (1) an exclusive royalty-free license to manufacture and distribute the Company’s ZBB EnerStore, zinc bromide flow battery, version three (V3) (50KW) and ZBB EnerSection, power and energy control center (up to 250KW) (the “Products”) in mainland China in the power supply management industry and (2) a non-exclusive royalty-free license to manufacture and distribute the Products in Hong Kong and Taiwan in the power supply management industry.

Pursuant to the Research and Development Agreement, Meineng Energy may request the Company to provide research and development services upon commercially reasonable terms and conditions.  Meineng Energy would pay the Company’s fully-loaded costs and expenses incurred in providing such services.

19

The Company had product sales of $12,230 and $70,328 to Meineng Energy during the three and nine months ended March 31, 2015, respectively.  The Company had product sales of $293,296 and $833,757 to Meineng Energy during the three and nine months ended March 31, 2014, respectively.

The condensed operating results for Meineng Energy for the three and nine months ended March 31, 2015 and March 31, 2014 are summarized as follows:

	Three months ended March 31,						Nine months ended March 31,
	2015			2014			2015			2014

NOTE 3 - GOING CONCERN

The accompanying condensed consolidated financial statements have been prepared on the basis of a going concern which contemplates that the Company will be able to realize assets and discharge its liabilities in the normal course of business.  Accordingly, they do not give effect to any adjustments that would be necessary should the Company be required to liquidate its assets.  The Company incurred a net loss of $9,472,006 attributable to ZBB Energy Corporation for nine months ended March 31, 2015, and as of March 31, 2015 has an accumulated deficit of $99,260,247 and total ZBB Energy Corporation equity of $17,249,881.  The ability of the Company to settle its total liabilities of $5,656,955 and to continue as a going concern is ultimately dependent upon increasing revenues and achieving long-term profitability.  The accompanying condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

We believe that cash and cash equivalents on hand at March 31, 2015, expected collections on the Lotte R&D Agreement and other potential sources of cash, will be sufficient to fund our current operations through the third quarter of fiscal year 2016.  However, there can be no assurances that unforeseen circumstances will not require the Company to raise additional investment capital to fund its operations.  If the Company is unable to obtain additional required funding, the Company’s financial condition and results of operations may be materially adversely affected and the Company may not be able to continue operations.

NOTE 9 - EMPLOYEE AND DIRECTOR EQUITY INCENTIVE PLANS

The Company previously adopted the 2002 Stock Option Plan (“2002 Plan”) in which a stock option committee could grant up to 1,000,000 shares to key employees or non-employee members of the board of directors.  The options vest in accordance with specific terms and conditions contained in an employment agreement.  If vesting terms and conditions are not defined in an employment agreement, then the options vest as determined by the stock option committee.  If the vesting period is not defined in an employment agreement or by the stock option committee, then the options immediately vest in full upon death, disability, or termination of employment.  Vested options expire upon the earlier of either the five year anniversary of the vesting date or termination of employment.  No shares are available to be issued under the 2002 Plan.

The Company also previously adopted the 2007 Equity Incentive Plan (“2007 Plan”) that authorized the board of directors or a committee to grant up to 300,000 shares to employees and directors of the Company.  Unless defined in an employment agreement or otherwise determined, the options vest ratably over a three-year period.  Options expire 10 years after the date of grant.  No shares are available to be issued under the 2007 Plan.

In November 2010, the Company adopted the 2010 Omnibus Long-Term Incentive Plan (“Omnibus Plan”) which authorizes a committee of the board of directors to grant stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, other stock-based awards and cash awards.  The Omnibus Plan authorized up to 800,000 shares plus shares of Common Stock underlying any outstanding stock option of other awards granted by any predecessor employee stock plan of the Company that is forfeited, terminated, or cancelled without issuance of shares, to employees, officers, non-employee members of the board of directors, consultants, and advisors.  Unless otherwise determined, options vest ratably over a three-year period and expire 8 years after the date of grant.

22

At the annual meeting of shareholders held on November 7, 2012 the Company’s shareholders approved an amendment of the Omnibus Plan which increased the number of shares of the Company’s common stock available for issuance pursuant to awards under the Omnibus Plan by 900,000 shares and the creation of the 2012 Non-Employee Director Equity Compensation Plan (“2012 Director Equity Plan”), under which the Company may issue up to 700,000 RSU awards and other equity awards to our non-employee directors pursuant to the Company’s director compensation policy.

At the annual meeting of shareholders held on November 18, 2014, the Company’s shareholders approved an amendment of the Omnibus Plan which increased the number of shares of the Company’s common stock available for issuance under the Omnibus Plan by 1,250,000.  The shareholders also approved an amendment of the 2012 Director Equity Plan which increased the number of shares of the Company’s common stock available for issuance under the 2012 Director Equity Plan by 1,000,000.  As of March 31, 2015, there are a total of 1,619,599 shares available to be issued under the Omnibus Plan and 456,804 shares available to be issued under the 2012 Director Equity Plan.

In aggregate for all plans, at March 31, 2015 there were outstanding a total of 1,664,778 options and 2,067,494 restricted stock units (“RSUs”).

The fair value of each option granted is estimated on the date of grant using the Black-Scholes option-pricing method.  The Company uses historical data to estimate the expected price volatility, the expected option life and the expected forfeiture rate.  The Company has not made any dividend payments nor does it have plans to pay dividends in the foreseeable future.  The following assumptions were used to estimate the fair value of options granted during the nine months ended March 31, 2015 and March 31, 2014 using the Black-Scholes option-pricing model:

	Nine months ended March 31,
	2015	2014
Expected life of option (years)	4	4
Risk-free interest rate	1.08 - 1.42%	0.95 - 1.20%
Assumed volatility	99.78 - 103.90%	94.35 - 154.68%
Expected dividend rate	0%	0%
Expected forfeiture rate	5.00 - 6.32%	4.91 - 5.62%

Time-vested and performance-based stock awards, including stock options and RSUs are accounted for at fair value at date of grant.  Compensation expense is recognized over the requisite service and performance periods.

During the three and nine months ended March 31, 2015, the Company’s results of operations include compensation expense for stock options and RSUs granted under its various equity incentive plans.  The amount recognized in the financial statements related to stock-based compensation was $302,908 and $1,156,720, based on the amortized grant date fair value of options and RSUs during the three and nine months ended March 31, 2015, respectively.

NOTE 11 - EQUITY

On August 27, 2014, the Company completed an underwritten public offering of its common stock at a price to the public of $1.12 per share.  The Company sold a total of 13,248,000 shares of its common stock in the offering for aggregate proceeds of approximately $14.8 million.  The Company received approximately $13.7 million of net proceeds from the offering, after deducting the underwriting discount and expenses.

On March 13, 2013, the Company entered into a Common Stock Purchase Agreement (“Purchase Agreement”) with Aspire Capital Fund, LLC, an Illinois limited liability company (“Aspire Capital”), which provided that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital was committed to purchase up to an aggregate of $10 million of shares of the Company’s common stock over the two-year term of the Purchase Agreement.  On August 18, 2014, the Company provided notice to Aspire Capital electing to terminate the Purchase Agreement.

On March 19, 2014, the Company completed an underwritten public offering of its common stock at a price to the public of $2.25 per share.  The Company sold a total of 6,325,000 shares of its common stock in the offering for aggregate proceeds of approximately $14.2 million.  The Company received approximately $13.0 million of net proceeds from the offering, after deducting the underwriting discount and expenses.

On October 31, 2013, the Company effected a reverse stock split of its common stock by a ratio of 1-for-5 (the “Reverse Split”).  As a result of the Reverse Split every five outstanding shares of Common Stock became one share of common stock.  No fractional shares were issued in connection with the Reverse Split.  A shareholder who would otherwise have been entitled to receive a fractional share of common stock received a cash payment equal to the closing sales price of the Company’s Common Stock on October 31, 2013 as reported on the NYSE MKT times the amount of the fractional share.  The Reverse Split did not change the number of shares of common or preferred stock that the Company is authorized to issue, or the par value of the Company’s common or preferred stock.  The Reverse Split resulted in a proportionate adjustment to the per share exercise price and the number of shares of common stock issuable upon the exercise of outstanding warrants and stock options, as well as the number of shares of common stock eligible for issuance under the Omnibus Plan and the 2012 Director Equity Plan.  All of the information in these financial statements has been presented to reflect the impact of the 1-for-5 Reverse Split on a retroactive basis.

On September 26, 2013 the Company entered into a Securities Purchase Agreement with certain investors providing for the sale of 3,000 shares of Series B Convertible Preferred Stock (the “Preferred Stock”).  Certain Directors of the Company purchased 500 shares.

Shares of Preferred Stock were sold for $1,000 per share (the “Stated Value”) and accrue dividends on the Stated Value at an annual rate of 10%.  The net proceeds to the Company, after deducting $90,127 of offering costs, were $2,903,034.  During the year ended June 30, 2014, 425 shares of Preferred Stock were converted into 470,171 shares of common stock of the Company.  At March 31, 2015, 2,575 shares of Preferred Stock were convertible into 3,143,380 shares of common stock of the Company (“Common Stock”) at a conversion price equal to $0.95.  Upon any liquidation, dissolution or winding up of the Corporation, holders of Preferred Stock are entitled to receive out of the assets of the Company an amount equal to two times the Stated Value, plus any accrued and unpaid dividends thereon.  At March 31, 2015 the liquidation preference of the Preferred Stock was $5,561,211.

In connection with the purchase of the Preferred Stock, investors received warrants to purchase a total of 3,157,897 shares of Common Stock at an exercise price of $0.95.  The warrants are exercisable at any time prior to September 27, 2016.  During the year ended June 30, 2014, 1,447,368 warrants were exercised via a cashless exercise resulting in the issuance of 850,169 shares of common stock of the Company.  In addition, the Company issued a total of 81,579 warrants to a placement agent in connection with the transaction.  These warrants expire on September 27, 2016.

NOTE 12 - COMMITMENTS

Leasing Activities

The Company leases its Australian research and development facility from a non-related Australian company under the terms of a lease that expires October 31, 2016.  The rental rate was $75,596 per year (A$72,431) and was subject to an annual CPI adjustment.  Rent expense was $20,835 and $66,961 for the three and nine months ended March 31, 2015 and $23,340 and $69,525 for the three and nine months ended March 31, 2014, respectively.  In July of 2011, the Company renewed the lease on its Australian research and development facility through October 2016 at a rental rate of $95,855 per year (A$95,000) subject to an annual CPI adjustment.

The Company also leased a building from an officer of its subsidiary, Tier Electronics LLC, who is also a shareholder and was a director, under a lease agreement that was due to expire on March 31, 2015.  Subsequently a lease termination agreement was entered into on October 20, 2013, which terminated the lease effective December 31, 2013 for a fee of $21,000.  No rent expense was incurred during the three and nine months ended March 31, 2015, and rent expense was $0 and $63,000 for the three and nine months ended March 31, 2014, respectively.  The Company was required to pay real estate taxes and other occupancy costs related to the facility.

The future payments required under the terms of the leases for fiscal periods subsequent to March 31, 2015 are as follows:

2015	$	19,316
2016		77,264
2017		25,755
	$	122,335

Employment Contracts

The Company has entered into employment contracts with executives and management personnel.  The contracts provide for salaries, bonuses and stock option grants, along with other employee benefits.  The employment contracts generally have no set term and can be terminated by either party.  There is a provision for payments of up to six months of annual salary as severance if the Company terminates a contract without cause, along with the acceleration of certain unvested stock option grants.

NOTE 13 - RETIREMENT PLANS

All Australian based employees are entitled to varying degrees of benefits on retirement, disability, or death.  The Company contributes to an accumulation fund on behalf of the employees under an award which is legally enforceable.

NOTE 14 - INCOME TAXES

The provision (benefit) for income taxes consists of the following:

	Nine months ended March 31,
	2015		2014
Current	$	-	$	(86,848	)
Deferred		-		-
Provision (benefit) for income taxes	$	-	$	(86,848	)

The Company accounts for income taxes using an asset and liability approach which generally requires the recognition of deferred income tax assets and liabilities based on the expected future income tax consequences of events that have previously been recognized in the Company’s financial statements or tax returns.  In addition, a valuation allowance is recognized if it is more likely than not that some or all of the deferred income tax assets will not be realized in the foreseeable future.  Deferred income tax assets are reviewed for recoverability based on historical taxable income, the expected reversals of existing temporary differences, tax planning strategies and projections of future taxable income.  As a result of this analysis, the Company has provided for a valuation allowance against its net deferred income tax assets as of March 31, 2015 and June 30, 2014.

The Company’s combined effective income tax rate differed from the U.S. federal statutory income rate as follows:

	Nine months ended March 31,
	2015		2014
Income tax (benefit) computed at the U.S. federal statutory rate		-34%		-34%
Foreign tax expense/(benefit)		0%		-2%
Change in valuation allowance		34%		34%
Total		0%		-2%

Significant components of the Company’s net deferred income tax assets as of March 31, 2015 and June 30, 2014 were as follows:

	March 31, 2015			June 30, 2014
Federal net operating loss carryforwards	$	25,561,649		$	22,238,624
Federal - other		2,961,351			2,737,404

Australia net operating loss carryforwards		1,497,779			1,497,779
Deferred income tax asset valuation allowance		(34,943,865	)		(29,221,082	)
Total deferred income tax assets	$	-		$	-

The Company has U.S. federal net operating loss carryforwards of approximately $75.2 million as of March 31, 2015, that expire at various dates between June 30, 2017 and 2034.  The Company also has $8.7 million in other federal deferred tax assets comprised principally of non-cash compensation, inventory and warranty reserves, and other intangible assets.  The Company has U.S. federal research and development tax credit carryforwards of approximately $247,000 as of March 31, 2015 that expire at various dates through June 30, 2033.  As of March 31, 2015, the Company has approximately $84.5 million of Wisconsin net operating loss carryforwards that expire at various dates between March 31, 2015 and 2028.  As of March 31, 2015, the Company also has approximately $5.0 million of Australian net operating loss carryforwards available to reduce future taxable income of its Australian subsidiaries with an indefinite carryforward period.

29

A reconciliation of the beginning and ending balance of unrecognized income tax benefits is as follows:

	March 31, 2015			June 30, 2014
Beginning balance	$	196,583		$	193,097
Effect of foreign currency translation		(37,123	)		3,486
Ending balance	$	159,460		$	196,583

The Company’s issuance of additional shares of common stock has constituted an ownership change under Section 382 of the Internal Revenue Code which places an annual dollar limit on the use of net operating loss (“NOL”) carryforwards and other tax attributes that may be utilized in the future.  The calculation of the annual limitation of usage is based on a percentage of the equity value immediately after any ownership change.  The annual amount of tax attributes that may be utilized after the change in ownership is limited.  Previous issuances of additional shares of common stock also resulted in ownership changes and the annual amount of tax attributes from previous years is limited as well.  The extent of any limitations on the usage of net operating losses has not been determined.  Since the valuation allowance fully reserves for all available carryovers, the effect of the reduction would be offset by a reduction in the valuation allowance.

NOTE 15 – SUBSEQUENT EVENT

On April 17, 2015, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Solar Power, Inc., a California corporation (“SPI”) pursuant to which we will issue and sell to SPI for an aggregate purchase price of $33,390,000 a total of (i) 8,000,000 shares (the “Purchased Common Shares”) of common stock and (ii) 28,048 shares (the “Purchased Preferred Shares”) of Series C Convertible Preferred Stock.  The aggregate purchase price for the Purchased Common Shares was based on a purchase price per share of $0.6678 and the aggregate purchase price for the Purchased Preferred Shares was determined based on price of $0.6678 per common equivalent. Pursuant to the Purchase Agreement, the Company will issue to SPI a warrant to purchase 50,000,000 shares of Common Stock for an aggregate purchase price of $36,729,000 (the “Warrant”).

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

ZBB Energy Corporation (“We,” “Us,” “Our,” “ZBB,” “ZBB Energy” or the “Company”) develops, licenses, and manufactures innovative energy management systems solutions serving the utility, commercial and industrial building and off-grid markets.  ZBB was incorporated in Wisconsin in 1998 and is headquartered in Menomonee Falls, Wisconsin, USA, with offices also located in Perth, Western Australia.

ZBB Energy develops and commercializes application solutions for advanced energy management systems critical to the transition from a “coal-centric economy” to one reliant on renewable energy sources.  These advanced systems directly connect wind and solar equipment to the grid and other systems that can form various levels of micro-grids as well as power quality regulation solutions.  ZBB Energy brings vital power control and energy storage solutions to problems caused by the incorporation of increasingly pervasive renewable energy generating assets that are part of the grid power transmission and distribution network used in commercial, industrial, and multi-tenant buildings.  The Company also develops and commercializes energy management systems for off-grid applications such as island or remote power.

Anhui Meineng Store Energy Co., Ltd. (the “JV Company” or “Meineng Energy”) was established in late 2011 to develop, produce, sell, distribute and service advanced storage batteries and power electronics in China.  The JV Company assembles and manufactures the Company’s products for sale in the power management industry on an exclusive basis in mainland China and on a non-exclusive basis in Hong Kong and Taiwan.

Our investment in the JV Company was made through ZBB PowerSav Holdings Limited (“Hong Kong Holdco”), a Hong Kong limited liability company, formed with PowerSav New Energy Holdings Limited.  We own 60% of Hong Kong Holdco’s equity interests.  We have the right to appoint a majority of the members of the Board of Directors of Hong Kong Holdco and Hong Kong Holdco has the right to appoint a majority of the members of the Board of Directors of the JV Company.  Our indirect interest in the JV Company equals approximately 30%.

Bradley L. Hansen, our President and Chief Operating Officer has served as the Chief Executive Officer of Meineng Energy since December 2011.  Mr. Hansen owns an indirect 6% equity interest in Meineng Energy.

Pursuant to a management services agreement Hong Kong Holdco will provide certain management services to the JV Company in exchange for a management services fee equal to five percent of the JV Company’s net sales for the five year period beginning on the first day of the first quarter in which the JV Company achieves operational breakeven results and three percent of the JV Company’s new sales for the subsequent three years, provided the payment of such fees will terminate upon the JV Company completing an initial public offering on a nationally recognized securities exchange.

On December 16, 2013, we entered into a Research and Development Agreement (the “R&D Agreement”) with Lotte Chemical Corporation (“Lotte”) pursuant to which we agreed to develop and provide to Lotte a Zinc Bromide chemical flow battery system, including a Zinc Bromide chemical flow battery module and related software (the “Product”), on the terms and conditions set forth in the R&D Agreement (the “Project”).  The Project is scheduled to continue until December 16, 2015, unless extended by the mutual agreement of the Company and Lotte.  Subject to the satisfaction of certain specified milestones, Lotte is required to make payments to us under the R&D Agreement totaling $3,000,000 over the term of the Project.

In April 2011, we entered into a Collaboration Agreement (the “Collaboration Agreement”) with Lotte, pursuant to which the Company and Lotte collaborated on the technical development of our third generation Zinc Bromide flow battery module (the “Version 3 Battery Module”) and Lotte received a fully paid-up, exclusive and royalty-free license to sell and manufacture the Version 3 Battery Module in South Korea and a non-exclusive royalty-bearing license to sell the Version 3 Battery Module in Japan, Thailand, Taiwan, Malaysia, Vietnam and Singapore.

31

On December 16, 2013, we entered into an Amended License Agreement with Lotte (the “Amended License Agreement”).  Pursuant to the Amended License Agreement, we granted to Lotte, (1) an exclusive and royalty-free limited license in South Korea to use the Company’s Zinc Bromide flow battery module, Zinc Bromide flow battery stack and the technical information and know how related to the intellectual property arising from the Project (collectively, the “Technology”) to manufacture or sell a Zinc Bromide flow battery (the “Lotte Product”) in South Korea and (2) a non-exclusive (a) royalty-free limited license for Lotte and its affiliates to use the Technology internally in all locations other than China and South Korea to manufacture the Lotte Product and (b) royalty-bearing limited license to sell the Lotte Product in all locations other than China, the United States and South Korea. Lotte is required to pay us a total license fee of $3,000,000 under the Amended License Agreement plus up to an additional $1,000,000 if certain specific milestones are successfully achieved.  In addition, Lotte is required to make ongoing royalty payments to the Company equal to a single digit percentage of Lotte’s sales of the Lotte Product outside of South Korea until December 31, 2019.  The license fees are subject to a 16.5% non-refundable South Korea withholding tax.

On April 17, 2015, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Solar Power, Inc., a California corporation (“SPI”) pursuant to which we will issue and sell to SPI for an aggregate purchase price of $33,390,000 a total of (i) 8,000,000 shares (the “Purchased Common Shares”) of common stock and (ii) 28,048 shares (the “Purchased Preferred Shares”) of Series C Convertible Preferred Stock.  The aggregate purchase price for the Purchased Common Shares was based on a purchase price per share of $0.6678 and the aggregate purchase price for the Purchased Preferred Shares was determined based on price of $0.6678 per common equivalent.  Pursuant to the Purchase Agreement, the Company will issue to SPI a warrant to purchase 50,000,000 shares of Common Stock for an aggregate purchase price of $36,729,000 (the “Warrant”).

Pursuant to the Securities Purchase Agreement, the Company will enter into a supply agreement with SPI pursuant to which the Company will sell and SPI will purchase certain products and services offered by the Company from time to time, including certain energy management system solutions for solar projects (the “Supply Agreement”).

The Purchased Preferred Shares will be sold for $1,000 per share and are convertible at a conversion price of $0.6678, prepaid at closing of the transaction; provided, that (A) the first one-fourth of the Purchased Preferred Shares only become convertible upon the completion of five megawatts worth of solar projects in accordance with the Supply Agreement (the “Projects”), (B) the second one-fourth (the “Series C-2 Preferred Stock”) only become convertible upon the completion of 15 megawatts worth of Projects, (C) the third one-fourth (the “Series C-3 Preferred Stock”) only become convertible upon the completion of 25 megawatts worth of Projects, and (D) the last one-fourth only become convertible upon the completion of 40 megawatts worth of Projects. The Warrant represents the right to acquire 50,000,000 shares of Common Stock at an exercise price equal to $0.7346.  The Warrant only becomes exercisable upon the completion of 40 megawatts worth of Projects.

The closing of the Purchase Agreement is expected to take place following satisfaction of various closing conditions, including obtaining the approval of the Company’s shareholders.

RISKS AND UNCERTAINTIES

The following discussion of the condensed consolidated financial position and results of operations of the Company should be read in conjunction with the condensed consolidated financial statements and notes thereto included elsewhere in this Form 10-Q and the Company’s annual report filed on Form 10-K for the fiscal year ended June 30, 2014.  In addition to the historical information, this discussion contains forward looking statements such as statements of the Company’s expectations, plans, objectives and beliefs.  These statements use such words as “may,” “will,” “expect,” “anticipate,” “believe,” “plan” and other similar terminology.  In addition to the risks and uncertainties faced generally by participants in the renewable energy industry, we face the following risks and uncertainties:

32

· We have incurred losses since our inception in 1998 and anticipate incurring continuing losses.

· We may require a substantial amount of additional funds to finance our capital requirements and the growth of our business, and we may not be able to raise a sufficient amount of funds, or be able to do so on terms favorable to us and our stockholders, or at all.

· Our stock price could be volatile and our trading volume may fluctuate substantially.

· Our industry is highly competitive and we may be unable to successfully compete.

· Our ability to achieve significant revenue growth will be dependent on the successful commercialization of our new products, including our third generation ZBB EnerStore zinc bromide flow battery and ZBB EnerSection power and energy control center.

· To achieve profitability, we will need to lower our costs and increase our margins, which we may not be able to do.

· If our products do not perform as planned, we could experience increased costs, lower margins and harm to our reputation.

· We need to continue to improve the performance of our products to meet future requirements and competitive pressures.

· We must build quality products to ensure acceptance of our products.

· To succeed, we will need to rapidly grow and we may not be successful in managing this rapid growth.

· Our relationships with our strategic partners may not be successful, and we may not be successful in establishing additional partnerships, which could adversely affect our ability to commercialize our products and services.

· We depend on sole and limited source suppliers and outsource selected component manufacturing, and shortages or delay of supplies of component parts may adversely affect our operating results until alternate sources can be developed.

· We have no experience manufacturing our products on a large-scale basis and may be unable to do so at our manufacturing facilities.

· We are subject to risks relating to product concentration and lack of revenue diversification.

· Our China joint venture could be adversely affected by the laws and regulations of the Chinese government, our lack of decision-making authority and disputes between us and the Joint Venture.

· Business practices in Asia may entail greater risk and dependence upon the personal relationships of senior management than is common in North America, and therefore some of our agreements with other parties in China and South Korea could be difficult or impossible to enforce.

· Our success depends on our ability to retain our managerial personnel and to attract additional personnel.

· We market and sell, and plan to market and sell, our products in numerous international markets.  If we are unable to manage our international operations effectively, our business, financial condition and results of operations could be adversely affected.

33

· Our sales cycle is lengthy and variable, which makes it difficult for us to forecast revenue and other operating results.

· Our increased emphasis on larger and more complex system solutions and customer concentration may adversely affect our ability to accurately predict the timing of revenues and to meet short-term expectations of operational results.

· Businesses and consumers might not adopt alternative energy solutions as a means for obtaining their electricity and power needs, and therefore our revenues may not increase, and we may be unable to achieve and then sustain profitability.

· The success of our business depends on our ability to develop and protect our intellectual property rights, which could be expensive.

· We may be subject to claims that we infringe the intellectual property rights of others, and unfavorable outcomes could harm our business.

· If our shareholders’ equity falls below the minimum requirement or we otherwise fail to satisfy all required continued listing requirements, our common stock may be delisted from the NYSE MKT, which would cause our common stock to become less liquid.

· We may engage in acquisitions that could disrupt our business, cause dilution to our stockholders and reduce our financial resources.

· We have never paid cash dividends and do not intend to do so.

NEW ACCOUNTING PRONOUNCEMENTS

Refer to Note 1 of the Notes to Condensed Consolidated Financial Statements for a discussion of recently issued accounting pronouncements.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of our financial statements conforms to accounting principles generally accepted in the United States of America, which requires management, in applying our accounting policies, to make estimates and assumptions that have an important impact on our reported amounts of assets, liabilities, revenue, expenses and related disclosures at the date of our financial statements.  On an on-going basis, management evaluates its estimates including those related to revenue recognition, inventory valuations, warranty obligations, asset impairments and income taxes.  Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.  Actual results may differ from management’s estimates.

CRITICAL ACCOUNTING ESTIMATES

Revenue Recognition

Application of the accounting principles related to the measurement and recognition of revenue requires the Company to make judgments and estimates.  Even for the same product, the Company has to interpret contract terms to determine the appropriate accounting treatments.  When services, installation and training, etc. are rendered with product sales, the Company determines whether the deliverables should be treated as separate units of accounting.  When there are multiple transactions with the same customer, significant judgments are made to determine whether separate contracts are considered as part of one arrangement according to the contract’s terms and conditions.  When the installed equipment is accepted by the customer in different periods, the Company determines whether the completed project is able to be used by the customer, whether the receivable is collectible and whether revenue is recognized by stages.

34

Revenue recognition is also impacted by various factors, including the credit-worthiness of the customer.  Estimates of these factors are evaluated periodically to assess the adequacy of the estimates.  If the estimates were changed, revenue would be impacted.

Excess and Obsolete Inventory

We determine the amount of inventory that is excess and obsolete using estimates of future demand for individual components of raw materials and finished goods.

To determine excess and obsolete inventory, we compare listings of existing piece parts and finished goods to future product demand and usage requirements.  We record a full valuation allowance for inventory quantities on hand in excess of two year’s expected usage.

We believe our accounting estimate related to excess and obsolete inventory is a critical accounting estimate because it requires us to make assumptions about future sales volumes and product mix, which can be highly uncertain.  Changes in these estimates can have a material effect on our financial statements.

Accrued Expenses

Accrued expenses consist of the Company’s present obligations for various expenses incurred during the period and include a reserve for estimated contract losses, other accrued expenses, and warranty obligations.  Included in accrued expenses as of March 31, 2015 is a reserve of approximately $1.1 million for a product upgrade initiative established in the fourth quarter of fiscal 2014.

Subsequent to commercialization, installation and commissioning of units in the field, the Company garnered meaningful insights that have resulted in system design modifications and other general upgrades that have improved the performance, efficiency, and reliability of its systems.  In the interest of enhancing customer satisfaction, the Company launched the product upgrade initiative to implement these improvements at certain locations of its installed base over fiscal years 2015 and 2016.

Warranty Provision

The Company’s products are generally covered by a warranty for 12 or 18 months.  The Company accrues for warranty costs as part of costs of sales based on associated material costs, technical labor costs, and associated overheads.

If the Company experiences an increase in warranty claims compared with historical experience, or if the cost of servicing warranty claims is greater than expected, the Company’s gross margin could be adversely affected.

Stock Based Compensation

The Company’s Board of Directors approves grants of stock options to employees to purchase our common stock.  Stock compensation expense is recorded based upon the estimated fair value of the stock option at the date of grant.  The accounting estimate related to stock-based compensation is considered a critical accounting estimate because estimates are made in calculating compensation expense including expected option lives, forfeiture rates and expected volatility.  Expected option lives and forfeiture rates may be different from estimates and may result in potential future adjustments, which would impact the amount of stock-based compensation expense recorded in a particular period.

RESULTS OF OPERATIONS

Three months ended March 31, 2015 compared with the three months ended March 31, 2014

Revenue:

Our revenues for the three months ended March 31, 2015 and March 31, 2014 were $584,817 and $4,572,318, respectively.  The decrease of $3,987,501 was the result of a $534,674 decrease in product sales, a $452,827 decrease in engineering and development revenues, and a $3,000,000 decrease in license revenues as compared to the three months ended March 31, 2014.  The Company received a $3,000,000 one-time upfront license fee under the Amended License Agreement with Lotte during the three months ended March 31, 2014.

35

Costs and Expenses:

Total costs and expenses for the three months ended March 31, 2015 and March 31, 2014 were $3,953,457 and $4,576,268, respectively.  This decrease of $622,811 in the three months ended March 31, 2015 was due to the following factors:

· $271,396 decrease in costs of product sales principally due to decreased product sales, partially offset by $85,000 in charges to the reserve for excess and obsolete inventory during the quarter, $77,000 of freight charges on inventory receipts and customer shipments, and $25,000 of costs incurred for training and maintenance on new manufacturing equipment.

· $550,076 increase in advanced engineering and development expenses due to $271,000 of higher salaries and related payroll taxes resulting from increased headcount year over year, $200,800 of additional supplies and materials used, and an additional $126,000 paid to contract employees during the quarter, offset by an $85,000 decrease in RD&E activity at the Australia facility;

· $830,373 decrease in selling, general, and administrative expenses due primarily to a $595,000 decrease in stock compensation expense, and a $495,000 non-refundable South Korea withholding tax related to the one-time upfront license fee under our Amended License Agreement with Lotte incurred during the prior year.  These decreases were partially offset by increases of $49,000 in wages and payroll taxes, $49,000 in travel expenses, $45,000 in recruiting fees, and $33,000 in accounting fees; and,

· $38,636 decrease in depreciation and amortization expense is a result of the full recognition of amortization expense of the Company’s intangible assets during the prior fiscal year.

Other Income (Expense):

Total other income (expense) for the three months ended March 31, 2015 increased by $143,496 to $224,642 from $81,146 for the three months ended March 31, 2014 due to a $154,301 increase in equity in loss of investee company.

Income Taxes (Benefit):

The benefit for income taxes during the three months ended March 31, 2015 decreased by $38,598 to $0 from $38,598 for the three months ended March 31, 2014.  Benefit for income taxes represents an estimate of a refundable research and development tax credit we expect to receive from the government of Australia for the fiscal year ended June 30, 2014 related to qualified expenditures we incurred during the year ended June 30, 2014.  During fiscal year 2015, we did not incur any research and development expenditures in Australia to qualify for this credit.

Net Loss:

Our net loss for the three months ended March 31, 2015 increased by $3,465,001 to $3,456,071 from the $8,930 net income for the three months ended March 31, 2014.  This increase in loss was primarily the result of decreased revenues and increased operating costs and expenses.

Nine months ended March 31, 2015 compared with the nine months ended March 31, 2014

Revenue:

Our revenues for the nine months ended March 31, 2015 and March 31, 2014 were $1,450,332 and $6,602,896, respectively.  The decrease of $5,152,564 was the result of a $1,701,734 decrease in product sales revenues, $450,830 decrease in engineering and development revenues, and a $3,000,000 decrease in license revenues as compared to the nine months ended March 31, 2014.  The Company received a $3,000,000 one-time upfront license fee under the Amended License Agreement with Lotte during the nine months ended March 31, 2014.

36

Costs and Expenses:

Total costs and expenses for the nine months ended March 31, 2015 and March 31, 2014 were $11,486,121 and $11,315,746, respectively.  This increase of $170,375 in the nine months ended March 31, 2015 was due to the following factors:

· $915,608 decrease in costs of product sales principally due to decreased product sales, partially offset by $330,000 in charges to the reserve for excess and obsolete inventory during the period ended, $118,000 of freight charges on inventory receipts and customer shipments,;

· $93,027 increase in cost of engineering and development for $202,223 of costs incurred on the Lotte research and development agreement for the nine months ended March 31, 2015 compared to $109,196 incurred for the nine months ended March 31, 2014;

· $1,023,743 increase in advanced engineering and development expenses due to $750,000 of higher salaries and related payroll taxes resulting from increased headcount year over year, $307,000 of paid contract employees, $118,000 of computer software purchases, and $95,000 of additional employee benefits.  This activity was partially offset by a $264,000 decrease in advanced engineering and development activity at the Company’s Australia location;

· $379,918 increase in selling, general, and administrative expenses due to a $215,000 increase in fees for outside consultants, $258,000 paid in recruitment fees, an additional $109,000 incurred for travel and meals expense, $47,000 of additional wages and related payroll taxes,  $48,000 of purchases for computers and software licenses, and $77,000 of other miscellaneous general expenses, partially offset by a prior year non-refundable South Korea withholding tax of $495,000 related to the one-time upfront license fee under our Amended License Agreement with Lotte; and,

· $410,705 decrease in depreciation and amortization expense as a result of the full recognition of amortization expense of the Company’s intangible assets during the prior fiscal year.

Other Income (Expense):

Total other income (expense) for the nine months ended March 31, 2015 increased by $1,107,170 to income of $682,432 from an expense of $424,738 for the nine months ended March 31, 2014 primarily as a result of the $1,257,407 gain on investment in investee company resulting from a third-party capital investment transaction with the investee company and a $45,643 decrease in interest expense, offset by a $213,792 increase in equity in loss of investee company.

On August 12, 2014, Meineng Energy received a cash investment of 20,000,000 RMB (about $3.2 million) from a third party for a post-closing valuation of $42 million.  During the nine months ended March 31, 2015, we recognized a $1,257,407 gain on the carrying value of our investment in Meineng Energy.  $481,870 of this gain is attributable to the noncontrolling interest, which provided a net gain of $775,537 to the Company.

Income Taxes (Benefit):

The benefit for income taxes during the nine months ended March 31, 2015 decreased by $86,848 to $0 from $86,848 for the nine months ended March 31, 2014.  Benefit for income taxes represents an estimate of a refundable research and development tax credit we expect to receive from the government of Australia for the fiscal year ended June 30, 2014 related to qualified expenditures we incurred during the year ended June 30, 2014.  During fiscal year 2015, we did not incur any research and development expenditures in Australia to qualify for this credit.

37

Net Loss:

Our net loss for the nine months ended March 31, 2015 increased by $4,725,176 to $9,472,006 from the $4,746,830 net loss for the nine months ended March 31, 2014.  This increase in loss was primarily the result of decreased revenues and increased operating costs and expenses.  This activity was partially offset by the recognized gain on investment in investee company as described above.

Liquidity and Capital Resources

Since our inception, our research, advanced engineering and development, and operations have been primarily financed through debt and equity financings, and engineering, government and other research and development contracts.  Total capital stock and paid in capital as of March 31, 2015 was $118,097,761.  We had a cumulative deficit of $99,260,247 as of March 31, 2015 compared to a cumulative deficit of $89,788,242 as of June 30, 2014.  At March 31, 2015 we had net working capital of $13,299,334 compared to June 30, 2014 net working capital of $8,723,032.  Our shareholders’ equity as of March 31, 2015 and June 30, 2014, exclusive of noncontrolling interests, was $17,249,881 and $11,863,187, respectively.

On September 26, 2013, the Company entered into a Securities Purchase Agreement with certain investors providing for the sale of 3,000 shares of Series B Convertible Preferred Stock (the “Preferred Stock”).  Shares of Preferred Stock were sold for $1,000 per share (the “Stated Value”) and accrue dividends on the Stated Value at an annual rate of 10%.  At March 31, 2015 the Preferred Stock was convertible into a total of 3,143,380 shares of common stock of the Company (“Common Stock”) at a conversion price equal to $0.95.  Upon any liquidation, dissolution or winding up of the Corporation, holders of Preferred Stock are entitled to receive out of the assets of the Company an amount equal to two times the Stated Value, plus any accrued and unpaid dividends thereon.  The net proceeds to the Company, after deducting $90,127 of offering costs, were $2,909,873.  At March 31, 2015 the liquidation preference of the Preferred Stock was $5,561,211.

On March 19, 2014, the Company completed an underwritten public offering of its common stock at a price to the public of $2.25 per share.  The Company sold a total of 6,325,000 shares of its common stock in the offering for aggregate proceeds of approximately $14.2 million.  The Company received approximately $13.0 million of net proceeds from the offering, after deducting the underwriting discount and expenses.

On August 27, 2014, we completed an underwritten public offering of our common stock at a price to the public of $1.12 per share.  We sold a total of 13,248,000 shares of our common stock in the offering for aggregate proceeds of approximately $14.8 million.  We received approximately $13.7 million of net proceeds from the offering, after deducting the underwriting discount and expenses.

At March 31, 2015, our principal sources of liquidity were our cash and cash equivalents which totaled $15,045,073, accounts receivable of $235,286, and expected collections on the Lotte R&D Agreement.

We believe that cash and cash equivalents on hand, expected collections on the Lotte R&D Agreement and other potential sources of cash, will be sufficient to fund our current operations through the third quarter of fiscal year 2016.  However, unless we are able to increase our revenues and achieve profitability we will likely require additional investment capital to fund our operations.

If we are unable to obtain additional required funding, we may not be able to:

· remain in operation;

· execute our growth plan;

· take advantage of future opportunities; or

· respond to customers and competition.

Operating Activities

Our operating activities used net cash of $8,199,285 for the nine months ended March 31, 2015.  Cash used in operations resulted from a net loss of $9,353,357, which was decreased by $886,600 in non-cash adjustments and by $267,472 in net changes to working capital.  Non-cash adjustments included a gain on investment in investee company of $1,257,407, $1,156,720 of stock compensation expense, $475,700 of depreciation expense, and $517,702 of equity in loss of investee company.  Net decreases in working capital were primarily due to increases of $124,439 of prepaids and other current assets, $41,627 of customer deposits, and $160,914 of accrued compensation and benefits, offset by decreases of $815,738 of accounts receivable, $163,742 of inventories, $33,587 of accounts payable, and $773,189 in accrued expenses.

38

Investing Activities

Our investing activities used net cash of $549,573 for the nine months ended March 31, 2015, primarily for issuance of a note receivable in the amount of $150,000 and $409,296 for purchases of property and equipment.

Financing Activities

Our financing activities provided net cash of $13,441,366 for the nine months ended March 31, 2015.  Net cash provided by financing activities was comprised principally of $14,837,760 in proceeds from the issuance of common stock, less common stock issuance costs of $1,148,023.  During the nine months ended March 31, 2015 we made repayments of $262,127 of principal on bank loans and notes payable.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements as of March 31, 2015.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended (Exchange Act), is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.  Our disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosures.  There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures.  Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives, and management necessarily is required to use its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Notes to Financial Statements

CHINA JOINT VENTURE

On August 30, 2011, the Company entered into agreements providing for establishment of a joint venture to develop, produce, sell, distribute and service advanced storage batteries and power electronics in China (the “Joint Venture”).  Joint Venture partners include ZBB PowerSav Holdings Limited (“Holdco”), AnHui XinLong Electrical Co. and Wuhu Huarui Power Transmission and Transformation Engineering Co.  The Joint Venture was established upon receipt of certain governmental approvals from China which were received in November 2011.

The Joint Venture operates through a jointly-owned Chinese company located in Wuhu City, Anhui Province named Anhui Meineng Store Energy Co., Ltd. (“Meineng Energy”).  Meineng Energy intends to initially assemble and ultimately manufacture the Company’s products for sale in the power management industry on an exclusive basis in mainland China and on a non-exclusive basis in Hong Kong and Taiwan.

The Company’s President and Chief Operating Officer (“President and COO”) has served as the Chief Executive Officer of Meineng Energy since December 2011.  The President and COO owns an indirect 6% equity interest in Meineng Energy.

In connection with the Joint Venture, on August 30, 2011 the Company and certain of its subsidiaries entered into the following agreements:

• Joint Venture Agreement of Anhui Meineng Store Energy Co., Ltd. (the “China JV Agreement”) by and between ZBB PowerSav Holdings Limited, a Hong Kong limited liability company (“Holdco”), and Anhui Xinrui Investment Co., Ltd, a Chinese limited liability company; and

• Limited Liability Company Agreement of ZBB PowerSav Holdings Limited by and between ZBB Cayman Corporation and PowerSav New Energy Holdings Limited (the “Holdco Agreement”).

In connection with the Joint Venture, upon establishment of Meineng Energy, the Company and certain of its subsidiaries entered into the following agreements:

• Management Services Agreement by and between Meineng Energy and Holdco (the “Management Services Agreement”);

• License Agreement by and between Holdco and Meineng Energy (the “License Agreement”); and

• Research and Development Agreement by and between the Company and Meineng Energy (the “Research and Development Agreement”).

Pursuant to the China JV Agreement, Meineng Energy was capitalized with approximately $13.6 million of equity capital.  The Company’s only capital contributions to the Joint Venture were the contribution of technology to Meineng Energy via the License Agreement and $200,000 in cash.  The Company’s indirect interest in Meineng Energy equaled approximately 33%.  On August 12, 2014, Meineng Energy received a cash investment of 20,000,000 RMB (approximately $3.2 million) from Wuhu Fuhai-Haoyan Venture Investment, L.P., a branch of Shenzhen Oriental Fortune Capital Co., Ltd., for a post-closing equity position of 8%.  Required governmental approval was obtained in October 2014.  This investment capital will be used to fund ongoing operations and development of the China market, and provided Meineng Energy a 250,000,000 RMB (approximately $42 million) post-closing valuation.  Following this investment, the Company’s indirect investment in Meineng Energy equals approximately 30%.  The Company’s indirect gain as a result of the investment was $775,537, which is net of the gain attributable to the noncontrolling interest of $481,870.

The Company’s investment in Meineng Energy was made through Holdco.  Pursuant to the Holdco Agreement, the Company contributed to Holdco technology via a license agreement with an agreed upon value of approximately $4.1 million and $200,000 in cash in exchange for a 60% equity interest and PowerSav agreed to contribute to Holdco $3.3 million in cash in exchange for a 40% equity interest.  The initial capital contributions (consisting of the Company’s technology contribution and one half of required cash contributions) were made in December 2011.  The subsequent capital contributions (consisting of one half of the required cash contribution) were made on May 16, 2012.  For financial reporting purposes, Holdco’s assets and liabilities are consolidated with those of the Company and PowerSav’s 40% interest in Holdco is included in the Company’s condensed consolidated financial statements as a noncontrolling interest.

The Company’s basis in the technology contributed to Holdco is $0 due to US GAAP requirements related to research and development expenditures.  The difference of approximately $4.1 million in the Company’s basis in this technology and the valuation of the technology by Meineng Energy is accounted for by the Company through the elimination of the amortization expense recognized by Meineng Energy related to the technology.

The Company has the right to appoint a majority of the members of the Board of Directors of Hong Kong Holdco and Hong Kong Holdco has the right to appoint a majority of the members of the Board of Directors of Meineng Energy.

Pursuant to the Management Services Agreement, Holdco will provide certain management services to Meineng Energy in exchange for a management services fee equal to five percent of Meineng Energy’s net sales for the five year period beginning on the first day of the first quarter in which the JV Company achieves operational breakeven results and three percent of Meineng Energy’s net sales for the subsequent three years, provided the payment of such fees will terminate upon Meineng Energy completing an initial public offering on a nationally recognized securities exchange.  To date, no management service fee revenues have been recognized by Holdco.

Pursuant to the Amended License Agreement dated July 1, 2014, Holdco granted to Meineng Energy (1) an exclusive royalty-free license to manufacture and distribute the Company’s ZBB EnerStore, zinc bromide flow battery, version three (V3) (50KW) and ZBB EnerSection, power and energy control center (up to 250KW) (the “Products”) in mainland China in the power supply management industry and (2) a non-exclusive royalty-free license to manufacture and distribute the Products in Hong Kong and Taiwan in the power supply management industry.

Pursuant to the Research and Development Agreement, Meineng Energy may request the Company to provide research and development services upon commercially reasonable terms and conditions.  Meineng Energy would pay the Company’s fully-loaded costs and expenses incurred in providing such services. 

The Company had product sales of $12,230 and $70,328 to Meineng Energy during the three and nine months ended March 31, 2015, respectively.  The Company had product sales of $293,296 and $833,757 to Meineng Energy during the three and nine months ended March 31, 2014, respectively.

The condensed operating results for Meineng Energy for the three and nine months ended March 31, 2015 and March 31, 2014 are summarized as follows:

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

ZBB Energy Corporation (“ZBB,” “we,” “us,” “our” or the “Company”) develops, licenses, and manufactures innovative energy management systems solutions serving the utility, commercial and industrial building and off-grid markets.  ZBB was incorporated in Wisconsin in 1998 and is headquartered in Menomonee Falls, Wisconsin, USA with offices also located in Perth, Western Australia.

ZBB Energy develops and commercializes application solutions for advanced energy management systems critical to the transition from a “coal-centric economy” to one reliant on renewable energy sources.  These advanced systems directly connect wind and solar equipment to the grid and other systems that can form various levels of micro-grids as well as power quality regulation solutions.  ZBB Energy brings vital power control and energy storage solutions to problems caused by the incorporation of increasingly pervasive renewable energy generating assets that are part of the grid power transmission and distribution network used in commercial, industrial, and multi-tenant buildings.  The Company also develops and commercializes energy management systems for off-grid applications such as island or remote power.

The condensed consolidated financial statements include the accounts of the Company and those of its wholly-owned subsidiaries ZBB Energy Pty Ltd. (formerly known as ZBB Technologies, Ltd.) which has an advanced engineering and development facility in Perth, Australia, Century West PNL, LLC, and its sixty percent owned subsidiary ZBB PowerSav Holdings Limited located in Hong Kong which was formed in connection with the Company’s investment in a China joint venture.

Recent Developments

On April 17, 2015, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Solar Power, Inc., a California corporation (“SPI”) pursuant to which we will issue and sell to SPI for an aggregate purchase price of $33,390,000 a total of (i) 8,000,000 shares (the “Purchased Common Shares”) of common stock and (ii) 28,048 shares (the “Purchased Preferred Shares”) of Series C Convertible Preferred Stock.  The aggregate purchase price for the Purchased Common Shares was based on a purchase price per share of $0.6678 and the aggregate purchase price for the Purchased Preferred Shares was determined based on price of $0.6678 per common equivalent. Pursuant to the Purchase Agreement, the Company will issue to SPI a warrant to purchase 50,000,000 shares of Common Stock for an aggregate purchase price of $36,729,000 (the "Warrant").

Pursuant to the Securities Purchase Agreement, the Company will enter into a supply agreement with SPI, pursuant to which the Company will sell and SPI will purchase certain products and services offered by the Company from time to time, including certain energy management system solutions for solar projects (the "Supply Agreement")

The Purchased Preferred Shares will be sold for $1,000 per share and are convertible at a conversion price of $0.6678, prepaid at closing of the transaction; provided, that (A) the first one-fourth of the Purchased Preferred Shares only become convertible upon the completion of five megawatts worth of solar projects in accordance with the Supply Agreement (the “Projects”), (B) the second one-fourth (the “Series C-2 Preferred Stock”) only become convertible upon the completion of 15 megawatts worth of Projects, (C) the third one-fourth (the “Series C-3 Preferred Stock”) only become convertible upon the completion of 25 megawatts worth of Projects, and (D) the last one-fourth only become convertible upon the completion of 40 megawatts worth of Projects. The Warrant represents the right to acquire 50,000,000 shares of Common Stock at an exercise price equal to $0.7346.  The Warrant only becomes exercisable upon the completion of 40 megawatts worth of Projects.

The closing of the Purchase Agreement is expected to take place following satisfaction of various closing conditions, including obtaining the approval of the Company’s shareholders.

Interim Financial Data

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements.  In the opinion of management, all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for fair presentation of the results of operations have been included.  Operating results for the three and nine month periods ended March 31, 2015 are not necessarily indicative of the results that might be expected for the year ending June 30, 2015.

The condensed consolidated balance sheet at June 30, 2014 has been derived from audited financial statements at that date, but does not include all of the information and disclosures required by US GAAP.  For a more complete discussion of accounting policies and certain other information, refer to the Company’s annual report filed on Form 10-K for the fiscal year ended June 30, 2014 filed with the Securities and Exchange Commission on September 29, 2014.

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly and majority-owned subsidiaries and have been prepared in accordance with US GAAP.  All significant intercompany accounts and transactions have been eliminated in consolidation.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, restricted cash on deposit, accounts receivable, a note receivable, accounts payable, and bank loans and notes payable.  The carrying amounts of the Company’s financial instruments approximate their respective fair values due to the relatively short-term nature of these instruments, except for the bank loans and notes payable.  The carrying amount of the bank loans and notes payable approximates fair value due to the interest rate and terms approximating those available to us for similar obligations.

The Company accounts for the fair value of financial instruments in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820.  Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level or pricing observability.  FASB ASC 820 describes a fair value hierarchy based on the following three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level 2 inputs are inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly, for similar assets or liabilities in active markets.

Level 3 inputs are unobservable inputs for the asset or liability.  As such, the prices or valuation techniques require inputs that are both significant to the fair value measurement and are unobservable.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less to be cash equivalents.  The Company maintains its cash deposits at financial institutions predominately in the United States, Australia, and Hong Kong.  The Company has not experienced any losses in such accounts.

Restricted Cash on Deposit

The Company had $60,178 and $69,901 in restricted cash on deposit as of March 31, 2015 and June 30, 2014, respectively, as collateral for certain credit arrangements.

Accounts Receivable

Credit is extended based on an evaluation of a customer’s financial condition.  Accounts receivable are stated at the amount the Company expects to collect from outstanding balances.  The Company records allowances for doubtful accounts based on customer-specific analysis and general matters such as current assessments of past due balances and economic conditions.  The Company writes off accounts receivable against the allowance when they become uncollectible.  Accounts receivable are stated net of an allowance for doubtful accounts of $10,878 as of March 31, 2015 and June 30, 2014.  The composition of accounts receivable by aging category is as follows as of:

	March 31, 2015		June 30, 2014
Current	$	54,396	$	902,545
30-60 days		-		-
60-90 days		1,396		-
Over 90 days		179,494		148,479
Total	$	235,286	$	1,051,024

Inventories

Inventories are stated at the lower of cost or market.  Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis.  The Company provides inventory write-downs based on excess and obsolete inventories determined primarily by future demand forecasts.  The write-down is measured as the difference between the cost of the inventory and market based upon assumptions about future demand and charged to the provision for inventory, which is a component of cost of sales.  At the point of the loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.

Note Receivable

The Company has one note receivable from an unrelated party.  The note matures on December 15, 2015 and is classified as “Note receivable” in the financial statements.  We regularly evaluate the financial condition of the borrower to determine if any reserve for uncollectible amount should be established.  To date, no such reserve is required.  See further discussion of the note receivable in Note 5.

Property, Plant and Equipment

Land, building, equipment, computers, furniture and fixtures are recorded at cost.  Maintenance, repairs and betterments are charged to expense as incurred.  Depreciation is provided for all plant and equipment on a straight-line basis over the estimated useful lives of the assets.  The estimated useful lives used for each class of depreciable asset are:

	Estimated Useful Lives
Manufacturing equipment	3 - 7 years
Office equipment	3 - 7 years
Building and improvements	7 - 40 years

The Company completed a review of the estimated useful lives of specific assets for the quarter ended March 31, 2015 and determined that there were no changes in the estimated useful lives of assets.

Impairment of Long-Lived Assets

In accordance with FASB ASC Topic 360, "Impairment or Disposal of Long-Lived Assets," the Company assesses potential impairments to its long-lived assets including property, plant, equipment and intangible assets when there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable. 

If such an indication exists, the recoverable amount of the asset is compared to the asset’s carrying value.  Any excess of the asset’s carrying value over its recoverable amount is expensed in the statement of operations.  In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate.  Management has determined that there were no long-lived assets impaired as of March 31, 2015 and June 30, 2014.

Investment in Investee Company

Investee companies that are not consolidated, but over which the Company exercises significant influence, are accounted for under the equity method of accounting.  Whether or not the Company exercises significant influence with respect to an investee depends on an evaluation of several factors including, among others, representation on the investee company’s board of directors and ownership level, which is generally a 20% to 50% interest in the voting securities of the investee company.  Under the equity method of accounting, an investee company’s accounts are not reported in the Company’s condensed consolidated balance sheets and statements of operations; however, the Company’s share of the earnings or losses of the investee company is reflected in the caption ‘‘Equity in loss of investee company” in the condensed consolidated statements of operations.  The Company’s carrying value in an equity method investee company is reported in the caption ‘‘Investment in investee company’’ in the Company’s condensed consolidated balance sheets.

When the Company’s carrying value in an equity method investee company is reduced to zero, no further losses are recorded in the Company’s condensed consolidated financial statements unless the Company guaranteed obligations of the investee company or has committed additional funding.  When the investee company subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized.

Goodwill

Goodwill is recognized as the excess cost of an acquired entity over the net amount assigned to assets acquired and liabilities assumed.  Goodwill is not amortized but reviewed for impairment annually as of June 30 or more frequently if events or changes in circumstances indicate that its carrying value may be impaired.  These conditions could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit.

The first step of the impairment test requires the comparing of a reporting unit’s fair value to its carrying value.  If the carrying value is less than the fair value, no impairment exists and the second step is not performed.  If the carrying value is higher than the fair value, there is an indication that impairment may exist and the second step must be performed to compute the amount of the impairment.  In the second step, the impairment is computed by estimating the fair values of all recognized and unrecognized assets and liabilities of the reporting unit and comparing the implied fair value of reporting unit goodwill with the carrying amount of that unit’s goodwill.  The Company determined fair value as evidenced by market capitalization, and concluded that there was no need for an impairment charge as of March 31, 2015 and June 30, 2014.

Accrued Expenses

Accrued expenses consist of the Company’s present obligations related to various expenses incurred during the period and includes a reserve for estimated contract losses, other accrued expenses, and warranty obligations.  Included in accrued expenses as of March 31, 2015 is a reserve of approximately $1.1 million for a product upgrade initiative established in the fourth quarter of fiscal 2014.

Subsequent to commercialization, installation and commissioning of units in the field, the Company garnered meaningful insights that have resulted in system design modifications and other general upgrades that have improved the performance, efficiency, and reliability of its systems.  In the interest of enhancing customer satisfaction, the Company launched the product upgrade initiative to implement these improvements at certain locations of its installed base over fiscal years 2015 and 2016.

Warranty Obligations

The Company typically warrants its products for twelve months after installation or eighteen months after date of shipment, whichever occurs first.  Warranty costs are provided for estimated claims and charged to cost of product sales as revenue is recognized.  Warranty obligations are also evaluated quarterly to determine a reasonable estimate for the replacement of potentially defective materials of all energy storage systems that have been shipped to customers.

While the Company actively engages in monitoring and improving its evolving battery and production technologies, there is only a limited product history and relatively short time frame available to test and evaluate the rate of product failure.  Should actual product failure rates differ from the Company’s estimates, revisions are made to the estimated rate of product failures and resulting changes to the liability for warranty obligations.  In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise.

As of March 31, 2015 and June 30, 2014, included in the Company’s accrued expenses were $395,059 and $731,910, respectively, related to warranty obligations.  The following is a summary of accrued warranty activity:

	Nine Months and Year Ended
	March 31, 2015			June 30, 2014
Beginning balance	$	731,910		$	479,873
Accruals for warranties during the period		151,644			741,412
Settlements during the period		(288,334	)		(673,588	)
Adjustments relating to preexisting warranties		(200,161	)		184,213
Ending balance	$	395,059		$	731,910

Revenue Recognition

Revenues are recognized when persuasive evidence of a contractual arrangement exits, delivery has occurred or services have been rendered, the seller’s price to buyer is fixed and determinable, and collectability is reasonably assured.  The portion of revenue related to installation and final acceptance, is deferred until such installation and final customer acceptance are completed.

From time to time, the Company may enter into separate agreements at or near the same time with the same customer.  The Company evaluates such agreements to determine whether they should be accounted for individually as distinct arrangements or whether the separate agreements are, in substance, a single multiple element arrangement.  The Company evaluates whether the negotiations are conducted jointly as part of a single negotiation, whether the deliverables are interrelated or interdependent, whether the fees in one arrangement are tied to performance in another arrangement, and whether elements in one arrangement are essential to another arrangement.  The Company’s evaluation involves significant judgment to determine whether a group of agreements might be so closely related that they are, in effect, part of a single arrangement.

Our collaboration agreements typically involve multiple elements or deliverables, including upfront fees, contract research and development, milestone payments, technology licenses or options to obtain technology licenses, and royalties.  For these arrangements, revenues are recognized in accordance with FASB ASC 605-25, “Revenue Recognition – Multiple Element Arrangements.”  The Company’s revenues associated with multiple element contracts is based on the selling price hierarchy, which utilizes vendor-specific objective evidence (“VSOE”) when available, third-party evidence (“TPE”) if VSOE is not available, and if neither is available then the best estimate of the selling price is used.  The Company utilizes best estimate for its multiple deliverable transactions as VSOE and TPE do not exist.  To be considered a separate element, the product or service in question must represent a separate unit under SEC Staff Accounting Bulletin 104, and fulfill the following criteria: the delivered item(s) has value to the customer on a standalone basis; there is objective and reliable evidence of the fair value of the undelivered item(s); and if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control. For arrangements containing multiple elements, revenue from time and materials based service arrangements is recognized as the service is performed.  Revenue relating to undelivered elements is deferred at the estimated fair value until delivery of the deferred elements.  If the arrangement does not meet all criteria above, the entire amount of the transaction is deferred until all elements are delivered.

The portion of revenue related to engineering and development is recognized ratably upon delivery of the goods or services pertaining to the underlying contractual arrangement or revenue is recognized as certain activities are performed by the Company over the estimated performance period.

Revenues from government funded research and development contracts are recognized proportionally as costs are incurred and compared to the estimated total research and development costs for each contract.  In many cases, the Company is reimbursed only a portion of the costs incurred or to be incurred on the contract.  Government funded research and development contracts are generally multi-year, cost-reimbursement and/or cost-share type contracts.  The Company is generally reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract.

The Company charges shipping and handling fees when products are shipped or delivered to a customer, and includes such amounts in product revenues and shipping costs in cost of sales.  The Company reports its revenues net of estimated returns and allowances.

Total revenues of $584,817 and $1,450,332 were recognized for the three and nine months ended March 31, 2015, respectively.  Revenues for the three months ended March 31, 2015 were comprised of two significant customers (88% of total revenue) and revenues for the nine months ended March 31, 2015 were comprised of two significant customers (79% of total revenue).  Total revenues of $4,572,318 and $6,602,896 were recognized for the three and nine months ended March 31, 2014, respectively.  Revenues for the three months ended March 31, 2014 consisted of one significant customer (83% of total revenue) and revenues for the nine months ended March 31, 2014 were comprised of two significant customers (84% of total revenue).

Engineering, Development, and License Revenues

We assess whether a substantive milestone exists at the inception of our agreements.  In evaluating if a milestone is substantive we consider whether:

• Substantive uncertainty exists as to the achievement of the milestone event at the inception of the arrangement;

• The achievement of the milestone involves substantive effort and can only be achieved based in whole or in part on our performance or the occurrence of a specific outcome resulting from our performance;

• The amount of the milestone payment appears reasonable either in relation to the effort expended or the enhancement of the value of the delivered item(s);

• There is no future performance required to earn the milestone; and

• The consideration is reasonable relative to all deliverables and payment terms in the arrangement.

If any of these conditions are not met, we do not consider the milestone to be substantive and we defer recognition of the milestone payment and recognize it as revenue over the estimated period of performance, if any.

On December 13, 2011, the Company entered into a joint development and license agreement with a global technology company to jointly develop flow batteries.  The objective of the joint development agreement was to develop low cost, high energy density grid scale flow battery stacks and systems that could lead to a significant cost reduction for grid level storage.  The Company recognized revenue under this agreement upon achievement of certain performance milestones.  The Company recognized $0 of revenue under this agreement for the three and nine months ended March 31, 2015 and $0 and $200,000 for the three and nine months ended March 31, 2014, respectively.

On April 8, 2011, the Company entered into a Collaboration Agreement (the “Collaboration Agreement”) with Honam Petrochemical Corporation, now known as Lotte Chemical Corporation (“Lotte”), pursuant to which the Company and Lotte collaborated on the technical development of the Company’s third generation Zinc Bromide flow battery module (the “Version 3 Battery Module”) and Lotte received a fully paid-up, exclusive and royalty-free license to sell and manufacture the Version 3 Battery Module in South Korea and a non-exclusive royalty-bearing license to sell the Version 3 Battery Module in Japan, Thailand, Taiwan, Malaysia, Vietnam and Singapore. 

On December 16, 2013, the Company and Lotte entered into a Research and Development Agreement (the “R&D Agreement”) pursuant to which the Company has agreed to develop and provide to Lotte a Zinc Bromide chemical flow battery system, including a Zinc Bromide chemical flow battery module and related software (the “Product”), on the terms and conditions set forth in the R&D Agreement (the “Project”).  The Project is scheduled to continue until December 16, 2015, unless extended by the mutual agreement of the Company and Lotte.  Subject to the satisfaction of certain specified milestones, Lotte is required to make payments to the Company under the R&D Agreement totaling $3,000,000 over the term of the Project.  ZBB recognizes revenue based upon a Performance Based Method pursuant to the model described in FASB ASC 980-605-25, where revenue is recognized based on the lesser of the amount of nonrefundable cash received or the amounts due based on the proportional amount of the total effort expected to be expended on the contract that has been provided to date, as substantial doubt that the milestones will be achieved does not exist.  The Company recognized $297,173 and $483,650 of revenue under this agreement for the three and nine months ended March 31, 2015, respectively and $750,000 of revenue under this agreement for the three and nine months ended March 31, 2014.

Additionally, on December 16, 2013, the Company and Lotte entered into an Amended License Agreement (the “Amended License”).  Pursuant to the Amended License Agreement, the Company granted to Lotte, (1) an exclusive and royalty-free limited license in South Korea to use the Company’s Zinc Bromide flow battery module, Zinc Bromide flow battery stack and the technical information and know how related to the intellectual property arising from the Project (collectively, the “Technology”) to manufacture or sell a Zinc Bromide flow battery (the “Lotte Product”) in South Korea and (2) a non-exclusive (a) royalty-free limited license for Lotte and its affiliates to use the Technology internally in all locations other than China and South Korea to manufacture the Lotte Product and (b) royalty-bearing limited license to sell the Lotte Product in all locations other than China, the United States and South Korea. Lotte is required to pay the Company a total license fee of $3,000,000 under the Amended License Agreement plus up to an additional $1,000,000 if certain specific milestones are successfully achieved.  In addition, Lotte is required to make ongoing royalty payments to the Company equal to a single digit percentage of Lotte’s sales of the Lotte Product outside of South Korea until December 31, 2019.  The license fees are subject to a 16.5% non-refundable South Korea withholding tax.

Overall since the agreement date, through March 31, 2015 there were $5,250,000 of payments received and $4,608,650 of revenue recognized under the Lotte agreements.

The Company recognized $297,173 in engineering and development revenues for the three months ended March 31, 2015 and $499,170 for the nine months ended March 31, 2015.  The Company recognized $750,000 and $950,000 for the nine months ended March 31, 2014 related to collaborative agreements.  Engineering and development costs related to the collaboration agreements totaled $33,078 and $202,223 for the three and nine months ended March 31, 2015.  Engineering and development costs related to the collaboration agreements totaled $65,560 and $109,196 for the three and nine months ended March 31, 2014, respectively.

As of March 31, 2015 and March 31, 2014, the Company had no unbilled amounts from engineering and development contracts in process.  The Company had received $673,030 and $0 in customer payments for engineering and development contracts, representing deposits in advance of performance of the contracted work, as of March 31, 2015, and June 30, 2014, respectively.  These amounts are included as a component of customer deposits in the condensed consolidated balance sheets.

Advanced Engineering and Development Expenses

In accordance with FASB ASC Topic 730, “Research and Development,” the Company expenses advanced engineering and development costs as incurred.  These costs consist primarily of materials, labor, and allocable indirect costs incurred to design, build, and test prototype units, as well as the development of manufacturing processes for these units.  Advanced engineering and development costs also include consulting fees and other costs.

To the extent these costs are separately identifiable, incurred and funded by advanced engineering and development type agreements with outside parties, they are shown separately on the condensed consolidated statements of operations as a “Cost of engineering and development.”

Stock-Based Compensation

The Company measures all “Share-Based Payments," including grants of stock options, restricted shares and restricted stock units to be recognized in its condensed consolidated statement of operations based on their fair values on the grant date, which is consistent with FASB ASC Topic 718, “Stock Compensation,” guidelines.

Accordingly, the Company measures share-based compensation cost for all share-based awards at the fair value on the grant date and recognition of share-based compensation over the service period for awards that are expected to vest.  The fair value of stock options is determined based on the number of shares granted and the price of the shares at grant, and calculated based on the Black-Scholes valuation model.

The Company compensates its outside directors primarily with restricted stock units (“RSUs”) rather than cash.  The grant date fair value of the restricted stock unit awards is determined using the closing stock price of the Company’s common stock on the day prior to the date of the grant, with the compensation expense amortized over the vesting period of restricted stock unit awards, net of estimated forfeitures.

The Company only recognizes expense to its statements of operations for those options or shares that are expected ultimately to vest, using two attribution methods to record expense, the straight-line method for grants with only service-based vesting or the graded-vesting method, which considers each performance period, for all other awards.  See further discussion of stock-based compensation in Note 9.

Advertising Expense

Advertising costs of $3,284 and $16,245 for the three months ended March 31, 2015 and March 31, 2014, respectively, and advertising costs of $36,546 and $49,859 for the nine months ended March 31, 2015 and March 31, 2014, respectively, were charged to selling, general, and administrative expenses as incurred.

Income Taxes

The Company records deferred income taxes in accordance with FASB ASC Topic 740, “Accounting for Income Taxes.”  FASB ASC Topic 740 requires recognition of deferred income tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted tax rates in effect for the year in which the differences are expected to reverse.  The Company establishes a valuation allowance when necessary to reduce deferred income tax assets to the amount expected to be realized.  There were no net deferred income tax assets recorded as of March 31, 2015 and June 30, 2014.

The Company applies a more-likely-than-not recognition threshold for all tax uncertainties as required under FASB ASC Topic 740, which only allows the recognition of those tax benefits that have a greater than fifty percent likelihood of being sustained upon examination by the taxing authorities.

The Company’s U.S. Federal income tax returns for the years ended June 30, 2011 through June 30, 2014 and the Company’s Wisconsin and Australian income tax returns for the years ended June 30, 2010 through June 30, 2014 are subject to examination by taxing authorities.  As of March 31, 2015, there were no examinations in progress.

Foreign Currency

The Company uses the United States dollar as its functional and reporting currency, while the Australian dollar and Hong Kong dollar are the functional currencies of its foreign subsidiaries.  Assets and liabilities of the Company’s foreign subsidiaries are translated into United States dollars at exchange rates that are in effect at the balance sheet date while equity accounts are translated at historical exchange rates.  Income and expense items are translated at average exchange rates which were applicable during the reporting period.  Translation adjustments are accumulated in accumulated other comprehensive loss as a separate component of equity in the condensed consolidated balance sheets. 

Loss per Share

The Company follows the FASB ASC Topic 260, “Earnings per Share,” provisions which require the reporting of both basic and diluted earnings (loss) per share.  Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period.  Diluted earnings (net loss) per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.  In accordance with the FASB ASC Topic 260, any anti-dilutive effects on net income (loss) per share are excluded.  For the nine months ended March 31, 2015 and March 31, 2014 there were 9,809,404 and 9,474,075 shares of common stock underlying convertible preferred stock, options, restricted stock units and warrants that are excluded, respectively.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable.

The Company maintains significant cash deposits primarily with two financial institutions. The Company has not previously experienced any losses on such deposits.  Additionally, the Company performs periodic evaluations of the relative credit ratings of these institutions as part of its banking strategy.

Concentrations of credit risk with respect to accounts receivable are limited due to accelerated payment terms in current customer contracts and creditworthiness of the current customer base.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions.  These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period.  It is reasonably possible that the estimates we have made may change in the near future.  Significant estimates underlying the accompanying condensed consolidated financial statements include those related to:

• the timing of revenue recognition;

• the allowance for doubtful accounts;

• provisions for excess and obsolete inventory;

• the lives and recoverability of property, plant and equipment and other long-lived assets, including goodwill;

• contract costs, losses, and reserves;

• warranty obligations;

• income tax valuation allowances;

• stock-based compensation; and

• valuation of warrants.

Reclassifications

Certain amounts previously reported have been reclassified to conform to the current presentation.

Segment Information

The Company has determined that it operates as one reportable segment. 

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date.  Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

In February 2015, the FASB issued ASU 2015-02 – Consolidation (Topic 810): Amendments to the Consolidation Analysis.  The amendments are intended to improve certain areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures.  The amendments simplify reporting requirements by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public companies in several industries that typically make use of limited partnerships or VIEs.  The amendment is effective for fiscal years beginning after December 31, 2015.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In January 2015, the FASB issued ASU 2015-01 – Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.  The amendment was issued to reduce complexity in the accounting standards by eliminating the concept of extraordinary items from US GAAP.  The amendment is effective for annual periods ending after December 15, 2015.  The change may be applied prospectively or retrospectively to all prior periods presented in the financial statements.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In August 2014, the FASB issued ASU 2014-15 – Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40).  The update requires management to perform a going concern assessment if there is substantial doubt about an entity’s ability to continue as a going concern within one year of the financial statement issuance date.  Under the new standard, the definition of substantial doubt incorporates a likeliness threshold of “probable” that is consistent with the current use of the term defined in US GAAP for loss contingencies (Topic 450 – Contingencies).  Management will need to consider conditions that are known and reasonably knowable at the financial statement issuance date and determine whether the entity will be able to meet its obligations within the one-year period.  Additional disclosures are required if it is probable that the entity will be unable to meet its current obligations.  The amendments in this ASU will be effective for annual periods ending after December 15, 2016.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In June 2014, the FASB issued ASU 2014-12 - Compensation – Stock Compensation (Topic 718).  The amendments require that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting and, accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award.  Compensation expense should be recognized in the period in which it becomes probable that the performance target will be achieved.  ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015.  The Company is required to adopt this standard beginning July 1, 2016.  ASU 2014-12 does not contain any new disclosure requirements.  The Company does not expect the adoption of ASU 2014-12 to have a material effect on our financial position, results of operations or cash flows.

In May 2014, the FASB issued ASU 2014-09 – Revenue from Contracts with Customers (Topic 606).  The amendments outline a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersede most current revenue recognition guidance, including industry-specific guidance.  The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  In applying the revenue model to contracts within its scope, an entity identifies the contract(s) with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to the performance obligations in the contract and recognizes revenue when the entity satisfies a performance obligation.  ASU 2014-09, which includes additional disclosure requirements regarding revenue, cash flows and obligations related to contracts with customers, will be effective for annual reporting periods beginning after December 15, 2016.  Early adoption is not permitted.  The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment.  The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations upon adoption.

In April 2014, the FASB issued ASU 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.  The update changes the requirements for reporting discontinued operations in Subtopic 205-20.  To be classified as a discontinued operation, the disposal of a component or group of components must represent a strategic shift that has, or will have, a major effect on an entity’s operations and financial results.  Examples include a disposal of a major geographic area, a major line of business or a major equity method investment.  The amendments in this ASU are effective prospectively for reporting periods beginning on or after December 15, 2014, with early adoption permitted.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU 2013-11 – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, similar tax loss, or a tax credit carryforward.  To the extent the tax benefit is not available at the reporting date under the governing tax law or if the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented as a liability and not combined with deferred tax assets.  ASU 2013-11 is effective for annual periods, and interim periods within those years, beginning after December 15, 2013.  The amendments are to be applied to all unrecognized tax benefits that exist as of the effective date and may be applied retrospectively to each prior reporting period presented.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In April 2013, the FASB issued ASU 2013-07 – Presentation of Financial Statements (Topic 205) – Liquidation Basis of Accounting.  The amendments require an entity to prepare its financial statements using the liquidation basis of accounting when liquidation is imminent.  Liquidation is imminent when the likelihood is remote that the entity will return from liquidation and either (a) a plan for liquidation is approved by the person or persons with the authority to make such a plan effective and the likelihood is remote that the execution of the plan will be blocked by other parties or (b) a plan for liquidation is being imposed by other forces (for example, involuntary bankruptcy).  If a plan for liquidation was specified in the entity’s governing documents from the entity’s inception (for example, limited-life entities), the entity should apply the liquidation basis of accounting only if the approved plan for liquidation differs from the plan for liquidation that was specified at the entity’s inception.  The amendments require financial statements prepared using the liquidation basis of accounting to present relevant information about an entity’s expected resources in liquidation by measuring and presenting assets at the amount of the expected cash proceeds from liquidation.  The entity should include in its presentation of assets any items it had not previously recognized under US GAAP but that it expects to either sell in liquidation or use in settling liabilities (for example, trademarks).  The amendments are effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein.  Entities should apply the requirements prospectively from the day that liquidation becomes imminent.  Early adoption is permitted.  The adoption did not have an impact on the Company’s consolidated financial statements in its present condition.

In March 2013, the FASB issued ASU 2013-05 – Foreign Currency Matters (Topic 830) – Parent’s Accounting for the Cumulative Translation Adjustment upon derecognition of Certain Subsidiaries or Group of Assets within a Foreign Entity or of an Investment in a Foreign Entity.  These amendments provide guidance on releasing cumulative translation adjustments when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or a group of assets that is a non-profit activity or a business within a foreign entity.  In addition, these amendments provide guidance on the release of cumulative translation adjustments in partial sales of equity method investments and in step acquisitions.  The amendments are effective for fiscal years and interim reporting periods within those years, beginning after December 15, 2013.  The amendments should be applied prospectively to derecognition events occurring after the effective date.  Prior periods should not be adjusted.  Early adoption is permitted.  If an entity elects to early adopt the amendments, it should apply them as of the beginning of the entity’s fiscal year of adoption.  The Company was required to adopt this standard beginning July 1, 2014.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU 2013-04 – Liabilities (Topic 405) – Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date.  These amendments provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in US GAAP.  Examples of obligations within this guidance are debt arrangements, other contractual obligations, and settled litigation and judicial rulings.  The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013.  These amendments shall be applied retrospectively to all prior periods presented for those obligations within the scope of this Subtopic that exist at the beginning of an entity’s fiscal year of adoption.  Early adoption is permitted.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

Subsequent Events [Abstract]

SUBSEQUENT EVENT

On April 17, 2015, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Solar Power, Inc., a California corporation (“SPI”) pursuant to which we will issue and sell to SPI for an aggregate purchase price of $33,390,000 a total of (i) 8,000,000 shares (the “Purchased Common Shares”) of common stock and (ii) 28,048 shares (the “Purchased Preferred Shares”) of Series C Convertible Preferred Stock.  The aggregate purchase price for the Purchased Common Shares was based on a purchase price per share of $0.6678 and the aggregate purchase price for the Purchased Preferred Shares was determined based on price of $0.6678 per common equivalent.  Pursuant to the Purchase Agreement, the Company will issue to SPI a warrant to purchase 50,000,000 shares of Common Stock for an aggregate purchase price of $36,729,000 (the "Warrant").

Pursuant to the Securities Purchase Agreement, the Company will enter into a supply agreement with SPI, pursuant to which the Company will sell and SPI will purchase certain products and services offered by the Company from time to time, including certain energy management system solutions for solar projects (the "Supply Agreement").

The Purchased Preferred Shares will be sold for $1,000 per share and are convertible at a conversion price of $0.6678, prepaid at closing of the transaction; provided, that (A) the first one-fourth of the Purchased Preferred Shares only become convertible upon the completion of five megawatts worth of solar projects in accordance with the Supply Agreement (the “Projects”), (B) the second one-fourth (the “Series C-2 Preferred Stock”) only become convertible upon the completion of 15 megawatts worth of Projects, (C) the third one-fourth (the “Series C-3 Preferred Stock”) only become convertible upon the completion of 25 megawatts worth of Projects, and (D) the last one-fourth only become convertible upon the completion of 40 megawatts worth of Projects. The Warrant represents the right to acquire 50,000,000 shares of Common Stock at an exercise price equal to $0.7346.  The Warrant only becomes exercisable upon the completion of 40 megawatts worth of Projects.

The closing of the Purchase Agreement is expected to take place following satisfaction of various closing conditions, including obtaining the approval of the Company’s shareholders.  The Company is currently evaluating the impact this agreement will have on its assessment of going concern.

Equity [Abstract]

EQUITY

On August 27, 2014, the Company completed an underwritten public offering of its common stock at a price to the public of $1.12 per share.  The Company sold a total of 13,248,000 shares of its common stock in the offering for aggregate proceeds of approximately $14.8 million.  The Company received approximately $13.7 million of net proceeds from the offering, after deducting the underwriting discount and expenses.

On March 13, 2013, the Company entered into a Common Stock Purchase Agreement (“Purchase Agreement”) with Aspire Capital Fund, LLC, an Illinois limited liability company (“Aspire Capital”), which provided that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital was committed to purchase up to an aggregate of $10 million of shares of the Company’s common stock over the two-year term of the Purchase Agreement.  On August 18, 2014, the Company provided notice to Aspire Capital electing to terminate the Purchase Agreement.

On March 19, 2014, the Company completed an underwritten public offering of its common stock at a price to the public of $2.25 per share.  The Company sold a total of 6,325,000 shares of its common stock in the offering for aggregate proceeds of approximately $14.2 million.  The Company received approximately $13.0 million of net proceeds from the offering, after deducting the underwriting discount and expenses.

On October 31, 2013, the Company effected a reverse stock split of its common stock by a ratio of 1-for-5 (the “Reverse Split”).  As a result of the Reverse Split every five outstanding shares of Common Stock became one share of common stock.  No fractional shares were issued in connection with the Reverse Split.  A shareholder who would otherwise have been entitled to receive a fractional share of common stock received a cash payment equal to the closing sales price of the Company’s Common Stock on October 31, 2013 as reported on the NYSE MKT times the amount of the fractional share.  The Reverse Split did not change the number of shares of common or preferred stock that the Company is authorized to issue, or the par value of the Company’s common or preferred stock.  The Reverse Split resulted in a proportionate adjustment to the per share exercise price and the number of shares of common stock issuable upon the exercise of outstanding warrants and stock options, as well as the number of shares of common stock eligible for issuance under the Omnibus Plan and the 2012 Director Equity Plan.  All of the information in these financial statements has been presented to reflect the impact of the 1-for-5 Reverse Split on a retroactive basis.

On September 26, 2013 the Company entered into a Securities Purchase Agreement with certain investors providing for the sale of 3,000 shares of Series B Convertible Preferred Stock (the “Preferred Stock”).  Certain Directors of the Company purchased 500 shares.

Shares of Preferred Stock were sold for $1,000 per share (the “Stated Value”) and accrue dividends on the Stated Value at an annual rate of 10%.  The net proceeds to the Company, after deducting $90,127 of offering costs, were $2,903,034.  During the year ended June 30, 2014, 425 shares of Preferred Stock were converted into 470,171 shares of common stock of the Company.  At March 31, 2015, 2,575 shares of Preferred Stock were convertible into 3,143,380 shares of common stock of the Company (“Common Stock”) at a conversion price equal to $0.95.  Upon any liquidation, dissolution or winding up of the Corporation, holders of Preferred Stock are entitled to receive out of the assets of the Company an amount equal to two times the Stated Value, plus any accrued and unpaid dividends thereon.  At March 31, 2015 the liquidation preference of the Preferred Stock was $5,561,211.

In connection with the purchase of the Preferred Stock, investors received warrants to purchase a total of 3,157,897 shares of Common Stock at an exercise price of $0.95.  The warrants are exercisable at any time prior to September 27, 2016.  During the year ended June 30, 2014, 1,447,368 warrants were exercised via a cashless exercise resulting in the issuance of 850,169 shares of common stock of the Company.  In addition, the Company issued a total of 81,579 warrants to a placement agent in connection with the transaction.  These warrants expire on September 27, 2016.

Summary Of Significant Accounting Policies Policies

Description of Business

Description of Business

ZBB Energy Corporation (“ZBB,” “we,” “us,” “our” or the “Company”) develops, licenses, and manufactures innovative energy management systems solutions serving the utility, commercial and industrial building and off-grid markets.  ZBB was incorporated in Wisconsin in 1998 and is headquartered in Menomonee Falls, Wisconsin, USA with offices also located in Perth, Western Australia.

ZBB Energy develops and commercializes application solutions for advanced energy management systems critical to the transition from a “coal-centric economy” to one reliant on renewable energy sources.  These advanced systems directly connect wind and solar equipment to the grid and other systems that can form various levels of micro-grids as well as power quality regulation solutions.  ZBB Energy brings vital power control and energy storage solutions to problems caused by the incorporation of increasingly pervasive renewable energy generating assets that are part of the grid power transmission and distribution network used in commercial, industrial, and multi-tenant buildings.  The Company also develops and commercializes energy management systems for off-grid applications such as island or remote power.

The condensed consolidated financial statements include the accounts of the Company and those of its wholly-owned subsidiaries ZBB Energy Pty Ltd. (formerly known as ZBB Technologies, Ltd.) which has an advanced engineering and development facility in Perth, Australia, Century West PNL, LLC, and its sixty percent owned subsidiary ZBB PowerSav Holdings Limited located in Hong Kong which was formed in connection with the Company’s investment in a China joint venture.

Recent Developments

On April 17, 2015, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Solar Power, Inc., a California corporation (“SPI”) pursuant to which we will issue and sell to SPI for an aggregate purchase price of $33,390,000 a total of (i) 8,000,000 shares (the “Purchased Common Shares”) of common stock and (ii) 28,048 shares (the “Purchased Preferred Shares”) of Series C Convertible Preferred Stock.  The aggregate purchase price for the Purchased Common Shares was based on a purchase price per share of $0.6678 and the aggregate purchase price for the Purchased Preferred Shares was determined based on price of $0.6678 per common equivalent.  Pursuant to the Purchase Agreement, the Company will issue to SPI a warrant to purchase 50,000,000 shares of Common Stock for an aggregate purchase price of $36,729,000 (the "Warrant").

Pursuant to the Securities Purchase Agreement, the Company will enter into a supply agreement with SPI, pursuant to which the Company will sell and SPI will purchase certain products and services offered by the Company from time to time, including certain energy management system solutions for solar projects (the "Supply Agreement").

 The Purchased Preferred Shares will be sold for $1,000 per share and are convertible at a conversion price of $0.6678, prepaid at closing of the transaction; provided, that (A) the first one-fourth of the Purchased Preferred Shares only become convertible upon the completion of five megawatts worth of solar projects in accordance with the Supply Agreement (the “Projects”), (B) the second one-fourth (the “Series C-2 Preferred Stock”) only become convertible upon the completion of 15 megawatts worth of Projects, (C) the third one-fourth (the “Series C-3 Preferred Stock”) only become convertible upon the completion of 25 megawatts worth of Projects, and (D) the last one-fourth only become convertible upon the completion of 40 megawatts worth of Projects. The Warrant represents the right to acquire 50,000,000 shares of Common Stock at an exercise price equal to $0.7346.  The Warrant only becomes exercisable upon the completion of 40 megawatts worth of Projects.

The closing of the Purchase Agreement is expected to take place following satisfaction of various closing conditions, including obtaining the approval of the Company’s shareholders.

Interim Financial Data

Interim Financial Data

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements.  In the opinion of management, all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for fair presentation of the results of operations have been included.  Operating results for the three and nine month periods ended March 31, 2015 are not necessarily indicative of the results that might be expected for the year ending June 30, 2015.

The condensed consolidated balance sheet at June 30, 2014 has been derived from audited financial statements at that date, but does not include all of the information and disclosures required by US GAAP.  For a more complete discussion of accounting policies and certain other information, refer to the Company’s annual report filed on Form 10-K for the fiscal year ended June 30, 2014 filed with the Securities and Exchange Commission on September 29, 2014.

Basis of Presentation

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly and majority-owned subsidiaries and have been prepared in accordance with US GAAP.  All significant intercompany accounts and transactions have been eliminated in consolidation.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, restricted cash on deposit, accounts receivable, a note receivable, accounts payable, and bank loans and notes payable.  The carrying amounts of the Company’s financial instruments approximate their respective fair values due to the relatively short-term nature of these instruments, except for the bank loans and notes payable.  The carrying amount of the bank loans and notes payable approximates fair value due to the interest rate and terms approximating those available to us for similar obligations.

The Company accounts for the fair value of financial instruments in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820.  Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level or pricing observability.  FASB ASC 820 describes a fair value hierarchy based on the following three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level 2 inputs are inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly, for similar assets or liabilities in active markets.

Level 3 inputs are unobservable inputs for the asset or liability.  As such, the prices or valuation techniques require inputs that are both significant to the fair value measurement and are unobservable.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less to be cash equivalents.  The Company maintains its cash deposits at financial institutions predominately in the United States, Australia, and Hong Kong.  The Company has not experienced any losses in such accounts.

Restricted Cash on Deposit

Restricted Cash on Deposit

The Company had $60,178 and $69,901 in restricted cash on deposit as of March 31, 2015 and June 30, 2014, respectively, as collateral for certain credit arrangements.

Accounts Receivable

Accounts Receivable

Credit is extended based on an evaluation of a customer’s financial condition.  Accounts receivable are stated at the amount the Company expects to collect from outstanding balances.  The Company records allowances for doubtful accounts based on customer-specific analysis and general matters such as current assessments of past due balances and economic conditions.  The Company writes off accounts receivable against the allowance when they become uncollectible.  Accounts receivable are stated net of an allowance for doubtful accounts of $10,878 as of March 31, 2015 and June 30, 2014.  The composition of accounts receivable by aging category is as follows as of:

	March 31, 2015		June 30, 2014
Current	$	54,396	$	902,545
30-60 days		-		-
60-90 days		1,396		-
Over 90 days		179,494		148,479
Total	$	235,286	$	1,051,024

Inventories

Inventories

Inventories are stated at the lower of cost or market.  Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis.  The Company provides inventory write-downs based on excess and obsolete inventories determined primarily by future demand forecasts.  The write-down is measured as the difference between the cost of the inventory and market based upon assumptions about future demand and charged to the provision for inventory, which is a component of cost of sales.  At the point of the loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.

Note Receivable

Note Receivable

The Company has one note receivable from an unrelated party.  The note matures on December 15, 2015 and is classified as “Note receivable” in the financial statements.  We regularly evaluate the financial condition of the borrower to determine if any reserve for uncollectible amount should be established.  To date, no such reserve is required.  See further discussion of the note receivable in Note 5.

Property, Plant and Equipment

Property, Plant and Equipment

Land, building, equipment, computers, furniture and fixtures are recorded at cost.  Maintenance, repairs and betterments are charged to expense as incurred.  Depreciation is provided for all plant and equipment on a straight-line basis over the estimated useful lives of the assets.  The estimated useful lives used for each class of depreciable asset are:

	Estimated Useful Lives
Manufacturing equipment	3 - 7 years
Office equipment	3 - 7 years
Building and improvements	7 - 40 years

The Company completed a review of the estimated useful lives of specific assets for the quarter ended March 31, 2015 and determined that there were no changes in the estimated useful lives of assets.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

In accordance with FASB ASC Topic 360, "Impairment or Disposal of Long-Lived Assets," the Company assesses potential impairments to its long-lived assets including property, plant, equipment and intangible assets when there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable.

If such an indication exists, the recoverable amount of the asset is compared to the asset’s carrying value.  Any excess of the asset’s carrying value over its recoverable amount is expensed in the statement of operations.  In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate.  Management has determined that there were no long-lived assets impaired as of March 31, 2015 and June 30, 2014.

Investment in Investee Company

Investment in Investee Company

Investee companies that are not consolidated, but over which the Company exercises significant influence, are accounted for under the equity method of accounting.  Whether or not the Company exercises significant influence with respect to an investee depends on an evaluation of several factors including, among others, representation on the investee company’s board of directors and ownership level, which is generally a 20% to 50% interest in the voting securities of the investee company.  Under the equity method of accounting, an investee company’s accounts are not reported in the Company’s condensed consolidated balance sheets and statements of operations; however, the Company’s share of the earnings or losses of the investee company is reflected in the caption ‘‘Equity in loss of investee company” in the condensed consolidated statements of operations.  The Company’s carrying value in an equity method investee company is reported in the caption ‘‘Investment in investee company’’ in the Company’s condensed consolidated balance sheets.

When the Company’s carrying value in an equity method investee company is reduced to zero, no further losses are recorded in the Company’s condensed consolidated financial statements unless the Company guaranteed obligations of the investee company or has committed additional funding.  When the investee company subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized.

Goodwill

Goodwill

Goodwill is recognized as the excess cost of an acquired entity over the net amount assigned to assets acquired and liabilities assumed.  Goodwill is not amortized but reviewed for impairment annually as of June 30 or more frequently if events or changes in circumstances indicate that its carrying value may be impaired.  These conditions could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit.

The first step of the impairment test requires the comparing of a reporting unit’s fair value to its carrying value.  If the carrying value is less than the fair value, no impairment exists and the second step is not performed.  If the carrying value is higher than the fair value, there is an indication that impairment may exist and the second step must be performed to compute the amount of the impairment.  In the second step, the impairment is computed by estimating the fair values of all recognized and unrecognized assets and liabilities of the reporting unit and comparing the implied fair value of reporting unit goodwill with the carrying amount of that unit’s goodwill.  The Company determined fair value as evidenced by market capitalization, and concluded that there was no need for an impairment charge as of March 31, 2015 and June 30, 2014.

Accrued Expenses

Accrued Expenses

Accrued expenses consist of the Company’s present obligations related to various expenses incurred during the period and includes a reserve for estimated contract losses, other accrued expenses, and warranty obligations.  Included in accrued expenses as of March 31, 2015 is a reserve of approximately $1.1 million for a product upgrade initiative established in the fourth quarter of fiscal 2014.

Subsequent to commercialization, installation and commissioning of units in the field, the Company garnered meaningful insights that have resulted in system design modifications and other general upgrades that have improved the performance, efficiency, and reliability of its systems.  In the interest of enhancing customer satisfaction, the Company launched the product upgrade initiative to implement these improvements at certain locations of its installed base over fiscal years 2015 and 2016.

Warranty Obligations

Warranty Obligations

The Company typically warrants its products for twelve months after installation or eighteen months after date of shipment, whichever occurs first.  Warranty costs are provided for estimated claims and charged to cost of product sales as revenue is recognized.  Warranty obligations are also evaluated quarterly to determine a reasonable estimate for the replacement of potentially defective materials of all energy storage systems that have been shipped to customers.

While the Company actively engages in monitoring and improving its evolving battery and production technologies, there is only a limited product history and relatively short time frame available to test and evaluate the rate of product failure.  Should actual product failure rates differ from the Company’s estimates, revisions are made to the estimated rate of product failures and resulting changes to the liability for warranty obligations.  In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise.

As of March 31, 2015 and June 30, 2014, included in the Company’s accrued expenses were $395,059 and $731,910, respectively, related to warranty obligations.  The following is a summary of accrued warranty activity:

	Nine Months and Year Ended
	March 31, 2015			June 30, 2014
Beginning balance	$	731,910		$	479,873
Accruals for warranties during the period		151,644			741,412
Settlements during the period		(288,334	)		(673,588	)
Adjustments relating to preexisting warranties		(200,161	)		184,213
Ending balance	$	395,059		$	731,910

Revenue Recognition

Revenue Recognition

Revenues are recognized when persuasive evidence of a contractual arrangement exits, delivery has occurred or services have been rendered, the seller’s price to buyer is fixed and determinable, and collectability is reasonably assured.  The portion of revenue related to installation and final acceptance, is deferred until such installation and final customer acceptance are completed.

From time to time, the Company may enter into separate agreements at or near the same time with the same customer.  The Company evaluates such agreements to determine whether they should be accounted for individually as distinct arrangements or whether the separate agreements are, in substance, a single multiple element arrangement.  The Company evaluates whether the negotiations are conducted jointly as part of a single negotiation, whether the deliverables are interrelated or interdependent, whether the fees in one arrangement are tied to performance in another arrangement, and whether elements in one arrangement are essential to another arrangement.  The Company’s evaluation involves significant judgment to determine whether a group of agreements might be so closely related that they are, in effect, part of a single arrangement.

Our collaboration agreements typically involve multiple elements or deliverables, including upfront fees, contract research and development, milestone payments, technology licenses or options to obtain technology licenses, and royalties.  For these arrangements, revenues are recognized in accordance with FASB ASC 605-25, “Revenue Recognition – Multiple Element Arrangements.”  The Company’s revenues associated with multiple element contracts is based on the selling price hierarchy, which utilizes vendor-specific objective evidence (“VSOE”) when available, third-party evidence (“TPE”) if VSOE is not available, and if neither is available then the best estimate of the selling price is used.  The Company utilizes best estimate for its multiple deliverable transactions as VSOE and TPE do not exist.  To be considered a separate element, the product or service in question must represent a separate unit under SEC Staff Accounting Bulletin 104, and fulfill the following criteria: the delivered item(s) has value to the customer on a standalone basis; there is objective and reliable evidence of the fair value of the undelivered item(s); and if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control. For arrangements containing multiple elements, revenue from time and materials based service arrangements is recognized as the service is performed.  Revenue relating to undelivered elements is deferred at the estimated fair value until delivery of the deferred elements.  If the arrangement does not meet all criteria above, the entire amount of the transaction is deferred until all elements are delivered.

The portion of revenue related to engineering and development is recognized ratably upon delivery of the goods or services pertaining to the underlying contractual arrangement or revenue is recognized as certain activities are performed by the Company over the estimated performance period.

Revenues from government funded research and development contracts are recognized proportionally as costs are incurred and compared to the estimated total research and development costs for each contract.  In many cases, the Company is reimbursed only a portion of the costs incurred or to be incurred on the contract.  Government funded research and development contracts are generally multi-year, cost-reimbursement and/or cost-share type contracts.  The Company is generally reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract.

The Company charges shipping and handling fees when products are shipped or delivered to a customer, and includes such amounts in product revenues and shipping costs in cost of sales.  The Company reports its revenues net of estimated returns and allowances.

Total revenues of $584,817 and $1,450,332 were recognized for the three and nine months ended March 31, 2015, respectively.  Revenues for the three months ended March 31, 2015 were comprised of two significant customers (88% of total revenue) and revenues for the nine months ended March 31, 2015 were comprised of two significant customers (79% of total revenue).  Total revenues of $4,572,318 and $6,602,896 were recognized for the three and nine months ended March 31, 2014, respectively.  Revenues for the three months ended March 31, 2014 consisted of one significant customer (83% of total revenue) and revenues for the nine months ended March 31, 2014 were comprised of two significant customers (84% of total revenue).

Engineering, Development, and License Revenues

Engineering, Development, and License Revenues

We assess whether a substantive milestone exists at the inception of our agreements.  In evaluating if a milestone is substantive we consider whether:

• Substantive uncertainty exists as to the achievement of the milestone event at the inception of the arrangement;

• The achievement of the milestone involves substantive effort and can only be achieved based in whole or in part on our performance or the occurrence of a specific outcome resulting from our performance;

• The amount of the milestone payment appears reasonable either in relation to the effort expended or the enhancement of the value of the delivered item(s);

• There is no future performance required to earn the milestone; and

• The consideration is reasonable relative to all deliverables and payment terms in the arrangement.

If any of these conditions are not met, we do not consider the milestone to be substantive and we defer recognition of the milestone payment and recognize it as revenue over the estimated period of performance, if any.

On December 13, 2011, the Company entered into a joint development and license agreement with a global technology company to jointly develop flow batteries.  The objective of the joint development agreement was to develop low cost, high energy density grid scale flow battery stacks and systems that could lead to a significant cost reduction for grid level storage.  The Company recognized revenue under this agreement upon achievement of certain performance milestones.  The Company recognized $0 of revenue under this agreement for the three and nine months ended March 31, 2015 and $0 and $200,000 for the three and nine months ended March 31, 2014, respectively.

On April 8, 2011, the Company entered into a Collaboration Agreement (the “Collaboration Agreement”) with Honam Petrochemical Corporation, now known as Lotte Chemical Corporation (“Lotte”), pursuant to which the Company and Lotte collaborated on the technical development of the Company’s third generation Zinc Bromide flow battery module (the “Version 3 Battery Module”) and Lotte received a fully paid-up, exclusive and royalty-free license to sell and manufacture the Version 3 Battery Module in South Korea and a non-exclusive royalty-bearing license to sell the Version 3 Battery Module in Japan, Thailand, Taiwan, Malaysia, Vietnam and Singapore. 

On December 16, 2013, the Company and Lotte entered into a Research and Development Agreement (the “R&D Agreement”) pursuant to which the Company has agreed to develop and provide to Lotte a Zinc Bromide chemical flow battery system, including a Zinc Bromide chemical flow battery module and related software (the “Product”), on the terms and conditions set forth in the R&D Agreement (the “Project”).  The Project is scheduled to continue until December 16, 2015, unless extended by the mutual agreement of the Company and Lotte.  Subject to the satisfaction of certain specified milestones, Lotte is required to make payments to the Company under the R&D Agreement totaling $3,000,000 over the term of the Project.  ZBB recognizes revenue based upon a Performance Based Method pursuant to the model described in FASB ASC 980-605-25, where revenue is recognized based on the lesser of the amount of nonrefundable cash received or the amounts due based on the proportional amount of the total effort expected to be expended on the contract that has been provided to date, as substantial doubt that the milestones will be achieved does not exist.  The Company recognized $297,173 and $483,650 of revenue under this agreement for the three and nine months ended March 31, 2015, respectively and $750,000 of revenue under this agreement for the three and nine months ended March 31, 2014.

Additionally, on December 16, 2013, the Company and Lotte entered into an Amended License Agreement (the “Amended License”).  Pursuant to the Amended License Agreement, the Company granted to Lotte, (1) an exclusive and royalty-free limited license in South Korea to use the Company’s Zinc Bromide flow battery module, Zinc Bromide flow battery stack and the technical information and know how related to the intellectual property arising from the Project (collectively, the “Technology”) to manufacture or sell a Zinc Bromide flow battery (the “Lotte Product”) in South Korea and (2) a non-exclusive (a) royalty-free limited license for Lotte and its affiliates to use the Technology internally in all locations other than China and South Korea to manufacture the Lotte Product and (b) royalty-bearing limited license to sell the Lotte Product in all locations other than China, the United States and South Korea. Lotte is required to pay the Company a total license fee of $3,000,000 under the Amended License Agreement plus up to an additional $1,000,000 if certain specific milestones are successfully achieved.  In addition, Lotte is required to make ongoing royalty payments to the Company equal to a single digit percentage of Lotte’s sales of the Lotte Product outside of South Korea until December 31, 2019.  The license fees are subject to a 16.5% non-refundable South Korea withholding tax.

Overall since the agreement date, through March 31, 2015 there were $5,250,000 of payments received and $4,608,650 of revenue recognized under the Lotte agreements.

The Company recognized $297,173 in engineering and development revenues for the three months ended March 31, 2015 and $499,170 for the nine months ended March 31, 2015.  The Company recognized $750,000 and $950,000 for the nine months ended March 31, 2014 related to collaborative agreements.  Engineering and development costs related to the collaboration agreements totaled $33,078 and $202,223 for the three and nine months ended March 31, 2015.  Engineering and development costs related to the collaboration agreements totaled $65,560 and $109,196 for the three and nine months ended March 31, 2014, respectively.

As of March 31, 2015 and March 31, 2014, the Company had no unbilled amounts from engineering and development contracts in process.  The Company had received $673,030 and $0 in customer payments for engineering and development contracts, representing deposits in advance of performance of the contracted work, as of March 31, 2015, and June 30, 2014, respectively.  These amounts are included as a component of customer deposits in the condensed consolidated balance sheets.

Advanced Engineering and Development Expenses

Advanced Engineering and Development Expenses

In accordance with FASB ASC Topic 730, “Research and Development,” the Company expenses advanced engineering and development costs as incurred.  These costs consist primarily of materials, labor, and allocable indirect costs incurred to design, build, and test prototype units, as well as the development of manufacturing processes for these units.  Advanced engineering and development costs also include consulting fees and other costs.

To the extent these costs are separately identifiable, incurred and funded by advanced engineering and development type agreements with outside parties, they are shown separately on the condensed consolidated statements of operations as a “Cost of engineering and development.”

Stock-Based Compensation

Stock-Based Compensation

The Company measures all “Share-Based Payments," including grants of stock options, restricted shares and restricted stock units to be recognized in its condensed consolidated statement of operations based on their fair values on the grant date, which is consistent with FASB ASC Topic 718, “Stock Compensation,” guidelines.

Accordingly, the Company measures share-based compensation cost for all share-based awards at the fair value on the grant date and recognition of share-based compensation over the service period for awards that are expected to vest.  The fair value of stock options is determined based on the number of shares granted and the price of the shares at grant, and calculated based on the Black-Scholes valuation model.

The Company compensates its outside directors primarily with restricted stock units (“RSUs”) rather than cash.  The grant date fair value of the restricted stock unit awards is determined using the closing stock price of the Company’s common stock on the day prior to the date of the grant, with the compensation expense amortized over the vesting period of restricted stock unit awards, net of estimated forfeitures.

The Company only recognizes expense to its statements of operations for those options or shares that are expected ultimately to vest, using two attribution methods to record expense, the straight-line method for grants with only service-based vesting or the graded-vesting method, which considers each performance period, for all other awards.  See further discussion of stock-based compensation in Note 9.

Advertising Expense

Advertising Expense

Advertising costs of $3,284 and $16,245 for the three months ended March 31, 2015 and March 31, 2014, respectively, and advertising costs of $36,546 and $49,859 for the nine months ended March 31, 2015 and March 31, 2014, respectively, were charged to selling, general, and administrative expenses as incurred.

Income Taxes

Income Taxes

The Company records deferred income taxes in accordance with FASB ASC Topic 740, “Accounting for Income Taxes.”  FASB ASC Topic 740 requires recognition of deferred income tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted tax rates in effect for the year in which the differences are expected to reverse.  The Company establishes a valuation allowance when necessary to reduce deferred income tax assets to the amount expected to be realized.  There were no net deferred income tax assets recorded as of March 31, 2015 and June 30, 2014.

The Company applies a more-likely-than-not recognition threshold for all tax uncertainties as required under FASB ASC Topic 740, which only allows the recognition of those tax benefits that have a greater than fifty percent likelihood of being sustained upon examination by the taxing authorities.

The Company’s U.S. Federal income tax returns for the years ended June 30, 2011 through June 30, 2014 and the Company’s Wisconsin and Australian income tax returns for the years ended June 30, 2010 through June 30, 2014 are subject to examination by taxing authorities.  As of March 31, 2015, there were no examinations in progress.

Foreign Currency

Foreign Currency

The Company uses the United States dollar as its functional and reporting currency, while the Australian dollar and Hong Kong dollar are the functional currencies of its foreign subsidiaries.  Assets and liabilities of the Company’s foreign subsidiaries are translated into United States dollars at exchange rates that are in effect at the balance sheet date while equity accounts are translated at historical exchange rates.  Income and expense items are translated at average exchange rates which were applicable during the reporting period.  Translation adjustments are accumulated in accumulated other comprehensive loss as a separate component of equity in the condensed consolidated balance sheets.

Loss per Share

Loss per Share

The Company follows the FASB ASC Topic 260, “Earnings per Share,” provisions which require the reporting of both basic and diluted earnings (loss) per share.  Basic earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period.  Diluted earnings (net loss) per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.  In accordance with the FASB ASC Topic 260, any anti-dilutive effects on net income (loss) per share are excluded.  For the nine months ended March 31, 2015 and March 31, 2014 there were 9,809,404 and 9,474,075 shares of common stock underlying convertible preferred stock, options, restricted stock units and warrants that are excluded, respectively.

Concentrations of Credit Risk

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable.

The Company maintains significant cash deposits primarily with two financial institutions. The Company has not previously experienced any losses on such deposits.  Additionally, the Company performs periodic evaluations of the relative credit ratings of these institutions as part of its banking strategy.

Concentrations of credit risk with respect to accounts receivable are limited due to accelerated payment terms in current customer contracts and creditworthiness of the current customer base.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions.  These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period.  It is reasonably possible that the estimates we have made may change in the near future.  Significant estimates underlying the accompanying condensed consolidated financial statements include those related to:

• the timing of revenue recognition;

• the allowance for doubtful accounts;

• provisions for excess and obsolete inventory;

• the lives and recoverability of property, plant and equipment and other long-lived assets, including goodwill;

• contract costs, losses, and reserves;

• warranty obligations;

• income tax valuation allowances;

• stock-based compensation; and

• valuation of warrants.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date.  Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

In February 2015, the FASB issued ASU 2015-02 – Consolidation (Topic 810): Amendments to the Consolidation Analysis.  The amendments are intended to improve certain areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures.  The amendments simplify reporting requirements by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public companies in several industries that typically make use of limited partnerships or VIEs.  The amendment is effective for fiscal years beginning after December 31, 2015.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In January 2015, the FASB issued ASU 2015-01 – Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.  The amendment was issued to reduce complexity in the accounting standards by eliminating the concept of extraordinary items from US GAAP.  The amendment is effective for annual periods ending after December 15, 2015.  The change may be applied prospectively or retrospectively to all prior periods presented in the financial statements.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In August 2014, the FASB issued ASU 2014-15 – Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40).  The update requires management to perform a going concern assessment if there is substantial doubt about an entity’s ability to continue as a going concern within one year of the financial statement issuance date.  Under the new standard, the definition of substantial doubt incorporates a likeliness threshold of “probable” that is consistent with the current use of the term defined in US GAAP for loss contingencies (Topic 450 – Contingencies).  Management will need to consider conditions that are known and reasonably knowable at the financial statement issuance date and determine whether the entity will be able to meet its obligations within the one-year period.  Additional disclosures are required if it is probable that the entity will be unable to meet its current obligations.  The amendments in this ASU will be effective for annual periods ending after December 15, 2016.  Early adoption is permitted.  The Company does not expect adoption of this guidance to have a significant impact on its consolidated financial statements.

In June 2014, the FASB issued ASU 2014-12 - Compensation – Stock Compensation (Topic 718).  The amendments require that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting and, accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award.  Compensation expense should be recognized in the period in which it becomes probable that the performance target will be achieved.  ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015.  The Company is required to adopt this standard beginning July 1, 2016.  ASU 2014-12 does not contain any new disclosure requirements.  The Company does not expect the adoption of ASU 2014-12 to have a material effect on our financial position, results of operations or cash flows.

In May 2014, the FASB issued ASU 2014-09 – Revenue from Contracts with Customers (Topic 606).  The amendments outline a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersede most current revenue recognition guidance, including industry-specific guidance.  The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  In applying the revenue model to contracts within its scope, an entity identifies the contract(s) with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to the performance obligations in the contract and recognizes revenue when the entity satisfies a performance obligation.  ASU 2014-09, which includes additional disclosure requirements regarding revenue, cash flows and obligations related to contracts with customers, will be effective for annual reporting periods beginning after December 15, 2016.  Early adoption is not permitted.  The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment.  The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations upon adoption.

In April 2014, the FASB issued ASU 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.  The update changes the requirements for reporting discontinued operations in Subtopic 205-20.  To be classified as a discontinued operation, the disposal of a component or group of components must represent a strategic shift that has, or will have, a major effect on an entity’s operations and financial results.  Examples include a disposal of a major geographic area, a major line of business or a major equity method investment.  The amendments in this ASU are effective prospectively for reporting periods beginning on or after December 15, 2014, with early adoption permitted.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU 2013-11 – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, similar tax loss, or a tax credit carryforward.  To the extent the tax benefit is not available at the reporting date under the governing tax law or if the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented as a liability and not combined with deferred tax assets.  ASU 2013-11 is effective for annual periods, and interim periods within those years, beginning after December 15, 2013.  The amendments are to be applied to all unrecognized tax benefits that exist as of the effective date and may be applied retrospectively to each prior reporting period presented.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In April 2013, the FASB issued ASU 2013-07 – Presentation of Financial Statements (Topic 205) – Liquidation Basis of Accounting.  The amendments require an entity to prepare its financial statements using the liquidation basis of accounting when liquidation is imminent.  Liquidation is imminent when the likelihood is remote that the entity will return from liquidation and either (a) a plan for liquidation is approved by the person or persons with the authority to make such a plan effective and the likelihood is remote that the execution of the plan will be blocked by other parties or (b) a plan for liquidation is being imposed by other forces (for example, involuntary bankruptcy).  If a plan for liquidation was specified in the entity’s governing documents from the entity’s inception (for example, limited-life entities), the entity should apply the liquidation basis of accounting only if the approved plan for liquidation differs from the plan for liquidation that was specified at the entity’s inception.  The amendments require financial statements prepared using the liquidation basis of accounting to present relevant information about an entity’s expected resources in liquidation by measuring and presenting assets at the amount of the expected cash proceeds from liquidation.  The entity should include in its presentation of assets any items it had not previously recognized under US GAAP but that it expects to either sell in liquidation or use in settling liabilities (for example, trademarks).  The amendments are effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein.  Entities should apply the requirements prospectively from the day that liquidation becomes imminent.  Early adoption is permitted.  The adoption did not have an impact on the Company’s consolidated financial statements in its present condition.

In March 2013, the FASB issued ASU 2013-05 – Foreign Currency Matters (Topic 830) – Parent’s Accounting for the Cumulative Translation Adjustment upon derecognition of Certain Subsidiaries or Group of Assets within a Foreign Entity or of an Investment in a Foreign Entity.  These amendments provide guidance on releasing cumulative translation adjustments when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or a group of assets that is a non-profit activity or a business within a foreign entity.  In addition, these amendments provide guidance on the release of cumulative translation adjustments in partial sales of equity method investments and in step acquisitions.  The amendments are effective for fiscal years and interim reporting periods within those years, beginning after December 15, 2013.  The amendments should be applied prospectively to derecognition events occurring after the effective date.  Prior periods should not be adjusted.  Early adoption is permitted.  If an entity elects to early adopt the amendments, it should apply them as of the beginning of the entity’s fiscal year of adoption.  The Company was required to adopt this standard beginning July 1, 2014.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU 2013-04 – Liabilities (Topic 405) – Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date.  These amendments provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in US GAAP.  Examples of obligations within this guidance are debt arrangements, other contractual obligations, and settled litigation and judicial rulings.  The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013.  These amendments shall be applied retrospectively to all prior periods presented for those obligations within the scope of this Subtopic that exist at the beginning of an entity’s fiscal year of adoption.  Early adoption is permitted.  The adoption of this pronouncement did not have a material impact on the Company’s consolidated financial statements.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

EMPLOYEE AND DIRECTOR EQUITY INCENTIVE PLANS

The Company previously adopted the 2002 Stock Option Plan (“2002 Plan”) in which a stock option committee could grant up to 1,000,000 shares to key employees or non-employee members of the board of directors.  The options vest in accordance with specific terms and conditions contained in an employment agreement.  If vesting terms and conditions are not defined in an employment agreement, then the options vest as determined by the stock option committee.  If the vesting period is not defined in an employment agreement or by the stock option committee, then the options immediately vest in full upon death, disability, or termination of employment.  Vested options expire upon the earlier of either the five year anniversary of the vesting date or termination of employment.  No shares are available to be issued under the 2002 Plan.

The Company also previously adopted the 2007 Equity Incentive Plan (“2007 Plan”) that authorized the board of directors or a committee to grant up to 300,000 shares to employees and directors of the Company.  Unless defined in an employment agreement or otherwise determined, the options vest ratably over a three-year period.  Options expire 10 years after the date of grant.  No shares are available to be issued under the 2007 Plan.

In November 2010, the Company adopted the 2010 Omnibus Long-Term Incentive Plan (“Omnibus Plan”) which authorizes a committee of the board of directors to grant stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, other stock-based awards and cash awards.  The Omnibus Plan authorized up to 800,000 shares plus shares of Common Stock underlying any outstanding stock option of other awards granted by any predecessor employee stock plan of the Company that is forfeited, terminated, or cancelled without issuance of shares, to employees, officers, non-employee members of the board of directors, consultants, and advisors.  Unless otherwise determined, options vest ratably over a three-year period and expire 8 years after the date of grant.

At the annual meeting of shareholders held on November 7, 2012 the Company’s shareholders approved an amendment of the Omnibus Plan which increased the number of shares of the Company’s common stock available for issuance pursuant to awards under the Omnibus Plan by 900,000 shares and the creation of the 2012 Non-Employee Director Equity Compensation Plan (“2012 Director Equity Plan”), under which the Company may issue up to 700,000 RSU awards and other equity awards to our non-employee directors pursuant to the Company’s director compensation policy.

At the annual meeting of shareholders held on November 18, 2014, the Company’s shareholders approved an amendment of the Omnibus Plan which increased the number of shares of the Company’s common stock available for issuance under the Omnibus Plan by 1,250,000.  The shareholders also approved an amendment of the 2012 Director Equity Plan which increased the number of shares of the Company’s common stock available for issuance under the 2012 Director Equity Plan by 1,000,000.  As of March 31, 2015, there are a total of 1,619,599 shares available to be issued under the Omnibus Plan and 456,804 shares available to be issued under the 2012 Director Equity Plan.

In aggregate for all plans, at March 31, 2015 there were outstanding a total of 1,664,778 options and 2,067,494 restricted stock units (“RSUs”).

The fair value of each option granted is estimated on the date of grant using the Black-Scholes option-pricing method.  The Company uses historical data to estimate the expected price volatility, the expected option life and the expected forfeiture rate.  The Company has not made any dividend payments nor does it have plans to pay dividends in the foreseeable future.  The following assumptions were used to estimate the fair value of options granted during the nine months ended March 31, 2015 and March 31, 2014 using the Black-Scholes option-pricing model:

	Nine months ended March 31,
	2015	2014
Expected life of option (years)	4	4
Risk-free interest rate	1.08 - 1.42%	0.95 - 1.20%
Assumed volatility	99.78 - 103.90%	94.35 - 154.68%
Expected dividend rate	0%	0%
Expected forfeiture rate	5.00 - 6.32%	4.91 - 5.62%

Time-vested and performance-based stock awards, including stock options and RSUs are accounted for at fair value at date of grant.  Compensation expense is recognized over the requisite service and performance periods.

During the three and nine months ended March 31, 2015, the Company’s results of operations include compensation expense for stock options and RSUs granted under its various equity incentive plans.  The amount recognized in the financial statements related to stock-based compensation was $302,908 and $1,156,720, based on the amortized grant date fair value of options and RSUs during the three and nine months ended March 31, 2015, respectively. 

Information with respect to stock option activity is as follows:

Income Tax Disclosure [Abstract]

INCOME TAXES

The provision (benefit) for income taxes consists of the following:

	Nine months ended March 31,
	2015		2014
Current	$	-	$	(86,848	)
Deferred		-		-
Provision (benefit) for income taxes	$	-	$	(86,848	)

The Company accounts for income taxes using an asset and liability approach which generally requires the recognition of deferred income tax assets and liabilities based on the expected future income tax consequences of events that have previously been recognized in the Company’s financial statements or tax returns.  In addition, a valuation allowance is recognized if it is more likely than not that some or all of the deferred income tax assets will not be realized in the foreseeable future.  Deferred income tax assets are reviewed for recoverability based on historical taxable income, the expected reversals of existing temporary differences, tax planning strategies and projections of future taxable income.  As a result of this analysis, the Company has provided for a valuation allowance against its net deferred income tax assets as of March 31, 2015 and June 30, 2014.

The Company’s combined effective income tax rate differed from the U.S. federal statutory income rate as follows:

	Nine months ended March 31,
	2015		2014
Income tax (benefit) computed at the U.S. federal statutory rate		-34%		-34%
Foreign tax expense/(benefit)		0%		-2%
Change in valuation allowance		34%		34%
Total		0%		-2%

Significant components of the Company’s net deferred income tax assets as of March 31, 2015 and June 30, 2014 were as follows:

	March 31, 2015			June 30, 2014
Federal net operating loss carryforwards	$	25,561,649		$	22,238,624
Federal - other		2,961,351			2,737,404
Wisconsin net operating loss carryforwards		4,923,086			2,747,275
Australia net operating loss carryforwards		1,497,779			1,497,779
Deferred income tax asset valuation allowance		(34,943,865	)		(29,221,082	)
Total deferred income tax assets	$	-		$	-

The Company has U.S. federal net operating loss carryforwards of approximately $75.2 million as of March 31, 2015, that expire at various dates between June 30, 2017 and 2034.  The Company also has $8.7 million in other federal deferred tax assets comprised principally of non-cash compensation, inventory and warranty reserves, and other intangible assets.  The Company has U.S. federal research and development tax credit carryforwards of approximately $247,000 as of March 31, 2015 that expire at various dates through June 30, 2033.  As of March 31, 2015, the Company has approximately $84.5 million of Wisconsin net operating loss carryforwards that expire at various dates between March 31, 2015 and 2028.  As of March 31, 2015, the Company also has approximately $5.0 million of Australian net operating loss carryforwards available to reduce future taxable income of its Australian subsidiaries with an indefinite carryforward period. 

A reconciliation of the beginning and ending balance of unrecognized income tax benefits is as follows:

	March 31, 2015			June 30, 2014
Beginning balance	$	196,583		$	193,097
Effect of foreign currency translation		(37,123	)		3,486
Ending balance	$	159,460		$	196,583

The Company’s issuance of additional shares of common stock has constituted an ownership change under Section 382 of the Internal Revenue Code which places an annual dollar limit on the use of net operating loss (“NOL”) carryforwards and other tax attributes that may be utilized in the future.  The calculation of the annual limitation of usage is based on a percentage of the equity value immediately after any ownership change.  The annual amount of tax attributes that may be utilized after the change in ownership is limited.  Previous issuances of additional shares of common stock also resulted in ownership changes and the annual amount of tax attributes from previous years is limited as well.  The extent of any limitations on the usage of net operating losses has not been determined.  Since the valuation allowance fully reserves for all available carryovers, the effect of the reduction would be offset by a reduction in the valuation allowance.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

GOING CONCERN

The accompanying condensed consolidated financial statements have been prepared on the basis of a going concern which contemplates that the Company will be able to realize assets and discharge its liabilities in the normal course of business.  Accordingly, they do not give effect to any adjustments that would be necessary should the Company be required to liquidate its assets.  The Company incurred a net loss of $9,472,006 attributable to ZBB Energy Corporation for nine months ended March 31, 2015, and as of March 31, 2015 has an accumulated deficit of $99,260,247 and total ZBB Energy Corporation equity of $17,249,881.  The ability of the Company to settle its total liabilities of $5,656,955 and to continue as a going concern is ultimately dependent upon increasing revenues and achieving long-term profitability.  The accompanying condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

We believe that cash and cash equivalents on hand at March 31, 2015, expected collections on the Lotte R&D Agreement and other potential sources of cash, will be sufficient to fund our current operations through the third quarter of fiscal year 2016.  However, there can be no assurances that unforeseen circumstances will not require the Company to raise additional investment capital to fund its operations.  If the Company is unable to obtain additional required funding, the Company’s financial condition and results of operations may be materially adversely affected and the Company may not be able to continue operations.
