1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Jun. 30, 2012

Notes to Financial Statements

Basis of Presentation

Basis of Presentation

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

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 in fully insured accounts at financial institutions predominately in the United States, Australia, and Hong Kong.  The Company has not experienced any losses in such accounts.

Accounts Receivable

Accounts Receivable

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 $80,000, as of June 30, 2012 and June 30, 2011.

Inventories

Inventories

 Inventories are stated at the lower of cost or market using the first-in, first-out (FIFO) or average cost methods.  The carrying value of inventories is reviewed for obsolescence on at least a quarterly basis or more frequently if warranted due to changes in conditions.  Market is determined on the basis of estimated net realizable values.

Property, Plant and Equipment

Property, Plant and Equipment

Land, building, equipment, computers and 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 during the year ended June 30, 2012. The Company determined that as a result of changes in the Company’s products and the related production process, actual lives for certain assets were shorter than the estimated useful lives for depreciation purposes. Therefore, the Company decreased the estimated useful lives of certain equipment.  The effect of this change in estimate increased depreciation expense and net loss attributable to ZBB Energy Corporation for the year ended June 30, 2012 by $319,000, and increased the net loss per share - basic and diluted for the year ended June 30, 2012 by $.01 per share.  The effect of this change in estimate will decrease annual depreciation expense for the years ending June 30, 2013, 2014, 2015 and 2016 by $96,000, $96,000, $87,000, and $40,000, respectively.

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 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 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 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 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.

Intangible Assets

Intangible Assets

Intangible assets generally result from business acquisitions.  The Company accounted for the January 21, 2011 acquisition of substantially all of the net assets of Tier Electronics LLC by assigning the purchase price to identifiable tangible and intangible assets and liabilities.  Assets acquired and liabilities assumed were recorded at their estimated fair values.  Intangible assets consist of a non-compete agreement, license agreement, and trade secrets.

Amortization is recorded for intangible assets with determinable lives. Intangible assets are amortized using the straight line method over the three year estimated useful lives of the respective assets.

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.

In September 2011, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) to Accounting Standards Codification (“ASC”) Topic 350, “Intangibles — Goodwill and Other.”  This ASU amends the guidance in ASC Topic 350-20 on testing for goodwill impairment. The revised guidance allows entities testing for goodwill impairment to have the option of performing a qualitative assessment before calculating the fair value of the reporting unit. If the Company determines, on the basis of qualitative factors, that it is more likely than not that the fair value of the reporting unit is less than the carrying amount, the two-step impairment test is required.  If we cannot determine on the basis of qualitative factors that goodwill is not impaired, the two-step impairment test is required.

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 June 30, 2012 and June 30, 2011.

The ASU does not change how goodwill is calculated or assigned to reporting units, nor does it revise the requirement to test annually for impairment. The ASU is limited to goodwill and does not amend the annual requirement for testing other indefinite-lived intangible assets for impairment. We adopted this ASU for our 2012 goodwill impairment testing. The ASU did not have a material impact on our consolidated financial statements.

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 and 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 $0 and $219,213 long-lived assets impaired as of June 30, 2012 and June 30, 2011, respectively (see Note 6).

Warranty Obligations

Warranty Obligations

The Company typically warrants its products for twelve months after installation or eighteen months after date of shipment, whichever first occurs. 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 June 30, 2012 and June 30, 2011, included in the Company’s accrued expenses were $418,557 and $413,203, respectively, related to warranty obligations.  Such amounts are included in accrued expenses in the accompanying consolidated balance sheets.

 The following is a summary of accrued warranty activity:

	Year Ended June 30,
	2012			2011
Beginning balance	$	413,203		$	520,000
Accruals for warranties during the period		196,753			176,662
Settlements during the period		(126,902	)		(283,459	)
Adjustments relating to preexisting warranties		(64,497	)		-
Ending balance	$	418,557		$	413,203

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.

For sales arrangements containing multiple elements (products or services), revenue relating to undelivered elements is deferred at the estimated fair value until delivery of the deferred elements. 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. If the arrangement does not meet all criteria above, the entire amount of the transaction is deferred until all elements are delivered. Revenue from time and materials based service arrangements is recognized as the service is performed.

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.

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

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.

Total revenues of $4,805,568 and $1,802,610 were recognized for the years ended June 30, 2012 and June 30, 2011, respectively, and were comprised of two significant customers (59% and 17% of total revenues) and three significant customers  for 2011 (39%, 12% and 10% of total revenues).  The Company had one significant customer with an outstanding accounts receivable balance of $146,702 (31% of accounts receivable, net) and $146,702 (85% of accounts receivable, net) at June 30, 2012 and June 30, 2011, respectively.

Engineering and Development Revenues

Engineering and Development Revenues

On April 8, 2011, the Company entered into a Collaboration Agreement (the “Collaboration Agreement”) with Honam Petrochemical Corporation (“Honam”), a division of LOTTE Petrochemical, pursuant to which the Company agreed with Honam to collaborate on the further technical development of the Company’s third generation zinc bromide flow battery module (the “Version 3 Battery Module”).  Pursuant to the Collaboration Agreement, Honam was required to pay the Company a total of $3,000,000 as follows:  (1) $1,000,000 within 10 days following the execution of the Collaboration Agreement (subsequently received on April 9, 2011); (2) $500,000 by June 30, 2011 (subsequently received on June 30, 2011); (3) $1,200,000 by October 10, 2011 (subsequently received on October 10, 2011) and (4) $300,000 within 10 days after a single Version 3 Battery Module test station  is set up at Honam’s research and development center (subsequently received on March 30, 2012).  The Company has recognized $3,000,000 as revenue as of June 30, 2012 based on performance milestones achieved.  Pursuant to the Collaboration Agreement, the parties are required to negotiate a license agreement under which upon the completion of the collaboration project and the receipt by the Company of all payments due under the Collaboration Agreement, the Company shall grant to Honam: (1) a fully paid-up, exclusive and royalty-free license to sell and manufacture the Version 3 Battery Module in Korea and (2) non-exclusive rights to sell the Version 3 Battery Module in Japan, Thailand, Taiwan, Malaysia, Vietnam and Singapore.  In connection with such non-exclusive rights, Honam is required to pay us a royalty.

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 is 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.  Under the terms of the joint development agreement, the Company received $175,000 in December 2011, and will receive payments of $75,000 every three months starting April 2012 through January 2013 (subsequently received $75,000 during April and June of 2012) and $100,000 every three months starting in April 2013 through January 2014.  The global technology company also purchased 933,333 shares of the Company’s common stock in December 2011 for $700,000.  The Company recognizes revenue under this agreement upon achievement of certain performance milestones.  The Company recognized $200,000 of revenue under this agreement in the year ended June 30, 2012.

Milestone payments under collaborative arrangements are triggered by the results of the Company’s engineering and development efforts. Milestones related to the Company’s development-based activities may include initiation of various phases of engineering and development activities, successful completion of a phase of development, or delivery of specified equipment or products. Due to the uncertainty involved in meeting these development-based milestones, the development-based milestones are considered to be substantial (i.e. not just achieved through passage of time) at the inception of the collaboration agreement. In addition, the amounts of the payments assigned thereto are considered to be commensurate with the enhancement of the value of the delivered intellectual property as a result of our performance. The Company’s involvement is necessary to the achievement of development-based milestones. The Company accounts for development-based milestones as revenue upon achievement of the substantive milestone events. In addition, upon the achievement of development-based milestone events, the Company has no future performance obligations related to any milestone payments.

Included in engineering and development revenues were $2,500,000 and $700,000 respectively, for the years ended June 30, 2012 and June 30, 2011 related to the collaborative agreements.  Engineering and development costs related to the collaboration agreements totaled $1,050,572 and $536,715 for the years ended June 30, 2012 and June 30, 2011.

On June 29, 2007, ZBB Energy Pty Ltd. (“ZBB Perth”), an Australian subsidiary of the Company, and the Commonwealth of Australia (the “Commonwealth”) represented by and acting through the Department of Environment and Water Resources (the “Department”), entered into an agreement for project funding under the Advanced Electricity Storage Technologies (“AEST”) program (the “AEST agreement”) whereby the Department agreed to provide funding to ZBB Perth for the development of an energy storage system to be used to demonstrate the storage and supply of renewable energy generated from photovoltaic solar panels and wind turbines already operational at the Commonwealth Scientific and Industrial Research Organization’s (“CSIRO”) Newcastle Energy Centre in New South Wales, Australia.

The AEST agreement provided for a three year term under which the Commonwealth provided $2.6 million in project funding over several periods as certain development progress “milestones” were met by ZBB Perth to the satisfaction of the Commonwealth.  

The Company owns any assets, including battery storage systems, acquired with the funding from the contract.  The Company fulfilled its obligations under the AEST agreement and received a final payment of $184,939 in December 2010 which was recognized as engineering and development revenues during the year ended June 30, 2011.  The Company granted the government of Australia a free, non-exclusive license to intellectual property created in the project for their own internal use.

As of June 30, 2012 and June 30, 2011, the Company had no unbilled amounts from engineering and development contracts in process. The Company had received $129,950 and $858,500 in customer payments for engineering and development contracts, representing deposits in advance of performance of the contracted work, as of June 30, 2012 and June 30, 2011, respectively.

Advanced Engineering and Development Expenses

Advanced Engineering and Development Expenses

The Company expenses advanced engineering and development costs as incurred. These costs consist primarily of labor, overhead, and materials to build prototype units, materials for testing, development of manufacturing processes and 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 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 consolidated statement of operations based on their fair values on the grant date, 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 RSUs were classified as liability awards as of June 30, 2010 because the RSUs were to be paid in cash upon vesting. On November 10, 2010, the June 30, 2010 RSUs were converted to stock based RSUs and were credited to additional paid-in capital. The grant date fair value of the restricted stock unit awards was 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 Note 10.

Income Taxes

Income Taxes

The Company records deferred income taxes in accordance with FASB ASC Topic 740, “Accounting for Income Taxes.” This ASC Topic 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 June 30, 2012 and June 30, 2011.

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, 2009 through June 30, 2012 and the Company’s Wisconsin and Australian income tax returns for the years ended June 30, 2008 through June 30, 2012 are subject to examination by taxing authorities.

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 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 years ended June 30, 2012 and June 30, 2011 there were 13,690,030 and 6,608,719 shares of common stock underlying options, restricted stock units and warrants that are excluded, respectively.

Concentrations of Credit Risk and Fair Value

Concentrations of Credit Risk and Fair Value

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 three financial institutions.  All deposits are fully insured as of June 30, 2012. 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 investment 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.

The carrying amounts of cash and cash equivalents, accounts receivable, other current assets, accounts payable and accrued expenses approximate fair value due to the short-term nature of these instruments. The carrying value of bank loans and notes payable approximate fair value based on their terms which reflect market conditions existing as of June 30, 2012 and June 30, 2011.

Comprehensive income (loss)

Comprehensive Income (Loss)

The Company reports its comprehensive income (loss) in accordance with the FASB ASC Topic 220 “Comprehensive Income”, which requires presentation of the components of comprehensive earnings. Comprehensive income (loss), consisting of net income (loss) for the period plus or minus any net currency translation adjustments, for the years ended June 30, 2012 and June 30, 2011 was as follows:

	Year ended June 30,
	2012			2011
Net loss	$	(13,920,940	)	$	(8,449,006	)
Net translation adjustment		(12,169	)		(9,700	)
Comprehensive loss	$	(13,933,109	)	$	(8,458,706	)

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. 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 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 and other intangible assets;

· contract costs and reserves;

· warranty obligations;

· income tax valuation allowances;

· stock-based compensation; and

· fair values of assets acquired and liabilities assumed in a business combination; and

· valuation of warrants

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In July 2012, the FASB amended its authoritative guidance related to testing indefinite-lived intangible assets for impairment.  Under the revised guidance, entities testing their indefinite-lived intangible assets for impairment have the option of performing a qualitative assessment before performing further impairment testing.  If entities determine, on a basis of qualitative factors, that it is more-likely-than-not that the asset is impaired, a quantitative test is required.  The guidance becomes effective in the beginning of the Company’s fiscal 2014, with early adoption permitted. The Company is currently evaluating the timing of adopting this guidance which is not expected to have an impact on the Company’s consolidated financial statements.

In September 2011, the FASB issued an update to ASC Topic 350, “Intangibles — Goodwill and Other.”  This ASU amends the guidance in ASC Topic 350-20 on testing for goodwill impairment. The revised guidance allows entities testing for goodwill impairment to have the option of performing a qualitative assessment before calculating the fair value of the reporting unit. The ASU does not change how goodwill is calculated or assigned to reporting units, nor does it revise the requirement to test annually for impairment. The ASU is limited to goodwill and does not amend the annual requirement for testing other indefinite-lived intangible assets for impairment. We adopted this ASU for our 2012 goodwill impairment testing. The adoption of this ASU did not impact on our consolidated financial statements.

In June 2011, the FASB issued new accounting guidance related to the presentation of comprehensive income (loss) that eliminates the current option to report other comprehensive income (loss) and its components in the statement of changes in equity. Under this guidance, an entity can elect to present items of net income (loss) and other comprehensive income (loss) in one continuous statement or two consecutive statements. This guidance is effective for us beginning July 1, 2012. We do not believe the adoption of this guidance will have a material effect on our consolidated financial statements and related disclosures.

In May 2011, the FASB issued updated accounting guidance related to fair value measurements and disclosures that result in common fair value measurements and disclosures between U.S. GAAP and International Financial Reporting Standards. This guidance includes amendments that clarify the application of existing fair value measurements and disclosures, in addition to other amendments that change principles or requirements for fair value measurements or disclosures. The adoption of this guidance did not have a material effect on our consolidated financial statements and related disclosures.
