2.         Summary of Significant Accounting Policies

The significant accounting policies and estimates used in preparation of the condensed consolidated financial statements are described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2017, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the Securities and Exchange Commission, or the SEC, on March 15, 2018. There have been no material changes in the Company’s significant accounting policies during the three months ended March 31, 2018 except for the implementation of Accounting Standards Update (“ASU”) No. 2016-18, Restricted Cash, “ASU 2016-18”, as described below.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”) and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all the information and footnotes required by such accounting principles for complete financial statements. In the opinion of management, all adjustments (which include normal recurring adjustments) considered necessary to present fairly each of the condensed consolidated balance sheet as of March 31, 2018, the condensed consolidated statements of operations for the three months ended March 31, 2018 and March 31, 2017, and the condensed consolidated statements of cash flows for the three months ended March 31, 2018 and March 31, 2017, as applicable have been made. The condensed consolidated balance sheet as of December 31, 2017 has been derived from our audited financial statements as of such date, but it does not include all disclosures required by U.S. GAAP. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the period ended December 31, 2017, which are included on Form 10-K filed with the Securities and Exchange Commission on March 15, 2018.

The results of operations for the three months ended March 31, 2018 are not necessarily indicative of results that may be expected for the year ended December 31, 2018.

Principles of consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its Subsidiaries, both of which are wholly-owned subsidiaries. Significant inter-company accounts and transactions have been eliminated in consolidation.

Use of estimates

The preparation of the condensed consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, the valuation of conversion features of convertible debt, valuation allowances for deferred tax assets, the determination of fair value of estimated asset retirement obligations, the determination of stock option expense and the determination of the fair value of stock warrants issued. Actual results could differ from those estimates.

Restricted cash

Restricted cash was comprised of funds held in escrow at Green Bank for the purpose of paying for the construction of the lead recycling plant building in McCarran, Nevada. During 2017, the building was completed and the funds held in escrow were dispersed.

In November 2016, the Financial Accounting Standards Board, FASB issued ASU No. 2016-18. The amendments in ASU 2016-18 require an entity to reconcile and explain the period-over-period change in total cash, cash equivalents and restricted cash within its statements of cash flows rather than reconciling and explaining the period-over-period change in total cash and cash equivalents (excluding restricted cash). The Company adopted this new ASU beginning January 1, 2018 using the required full retrospective approach. The adoption of this standard resulted in an increase in net cash used in investing activities of $548,000 in the condensed consolidated statements of cash flows for the three months ended March 31, 2017. As there is no restricted cash at March 31, 2018 or December 31, 2017, there is no effect on the three-month period ending March 31, 2018.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the condensed consolidated statements of financial position that sum to the total of the same amounts shown in the condensed consolidated statement of cash flows (in thousands):

Net loss per share

Basic net loss per share is computed by dividing net loss by the weighted average number of vested shares outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive common securities, including convertible notes, options and warrants. Potential dilutive common shares include the dilutive effect of the common stock underlying in-the-money stock options as is calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of an option and the average amount of compensation cost, if any, for future services that the Company has not yet recognized when the option is exercised, are assumed to be used to repurchase shares in the current period.

For all periods presented in this report, convertible notes, stock options, and warrants were not included in the computation of diluted net loss per share because such inclusion would have had an antidilutive effect.

Segment and geographic information

Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment, and the Company operates in only one geographic segment.

Concentration of credit risk

Seventy-nine percent of revenue for the three-month period ended March 31, 2018 and Ninety-seven percent of accounts receivable at March 31, 2018 was derived from or attributable to Johnson Controls Battery Group, Inc.

Recent accounting pronouncements

In February 2016, the FASB issued ASU 2016-02 - Leases (ASC 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors).  The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today.  ASC 842 supersedes the previous leases standard, ASC 840 Leases. The standard is effective on January 1, 2019, with early adoption permitted. The Company is in the process of evaluating the impact of this new guidance.

There were no other recent accounting pronouncements or changes in accounting pronouncements during the three months ended March 31, 2018 that are of significance or potential significance to the Company.
