Summary of Significant Accounting Policies | NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates for the three months ended March 31, 2020 and 2019 include estimates for costs to complete open contracts, allowance for doubtful accounts on accounts receivable, the estimates for obsolete inventory, the useful life of property and equipment, assumptions used in assessing impairment of long-term assets, estimates of current and deferred income taxes and deferred tax valuation allowances, the fair value of non-cash equity transactions, and the fair value of equity incentives. Fair Value of Financial Instruments and Fair Value Measurements The Company adopted the guidance of Accounting Standards Codification (“ASC”) 820 for fair value measurements which clarifies the definition of fair value, prescribes methods for measuring fair value, and establishes a fair value hierarchy to classify the inputs used in measuring fair value as follows: Level 1-Inputs are unadjusted quoted prices in active markets for identical assets or liabilities available at the measurement date. Level 2-Inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data. Level 3-Inputs are unobservable inputs which reflect the reporting entity’s own assumptions on what assumptions the market participants would use in pricing the asset or liability based on the best available information. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, loans and lines of credit, accounts payable, accrued expenses, and other payables approximate their fair market value based on the short-term maturity of these instruments. The Company analyzes all financial and non-financial instruments with features of both liabilities and equity under the Financial Accounting Standards Board (“FASB”) accounting standard for such instruments. Under this standard, financial and non-financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company accounts for no instruments at fair value using level 3 valuation. ASC 825-10 “Financial Instruments”, allows entities to voluntarily choose to measure certain financial assets and liabilities at fair value (fair value option). The fair value option may be elected on an instrument-by-instrument basis and is irrevocable, unless a new election date occurs. If the fair value option is elected for an instrument, unrealized gains and losses for that instrument should be reported in earnings at each subsequent reporting date. The Company did not elect to apply the fair value option to any outstanding instruments. Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, the Company considers all highly liquid instruments with a maturity of three months or less at the purchase date and money market accounts to be cash equivalents. Accounts Receivable Accounts receivable are presented net of an allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for estimated losses. The Company reviews the accounts receivable on a periodic basis and makes general and specific allowance when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balance, the Company considers many factors, including the age of the balance, a customer’s historical payment history, its current credit-worthiness and current economic trends. Accounts are written off after exhaustive efforts at collection. The Company only grants credit terms to established customers who are deemed to be financially responsible. The expense associated with the allowance for doubtful accounts is recognized as general and administrative expense. Inventory Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out (FIFO) method based on prices paid for inventory items. This valuation requires us to make judgments, based on currently available information, about the likely method of disposition, such as sales to individual customers and expected recoverable values. Property and Equipment Property and equipment are stated at cost and are depreciated using the straight-line method over their estimated useful lives, which range from three to ten years. Leasehold improvements are depreciated over the shorter of the useful life or lease term including scheduled renewal terms. Maintenance and repairs are charged to expense as incurred. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in other income or expense in the year of disposition. The Company examines the possibility of decreases in the value of these assets when events or changes in circumstances reflect the fact that their recorded value may not be recoverable. Impairment of Long-Lived Assets In accordance with ASC Topic 360, the Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable, or at least annually. The Company recognizes an impairment loss when the sum of expected undiscounted future cash flows is less than the carrying amount of the asset. The amount of impairment is measured as the difference between the asset’s estimated fair value and its book value. The Company did not record any impairment charge for the three months ended March 31, 2020 or 2019. Revenue Recognition We adopted ASC Topic 606, Revenue from Contracts with Customers Identification of the contract, or contracts, with a customer A contract with a customer exists when (i) we enter into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, (ii) the contract has commercial substance and, (iii) we determine that collection of substantially all consideration for goods or services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. We apply judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer. Identification of the performance obligations in the contract Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the goods or service either on its own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. When a contract includes multiple promised goods or services, we apply judgment to determine whether the promised goods or services are capable of being distinct and are distinct within the context of the contract. If these criteria are not met, the promised goods or services are accounted for as a combined performance obligation. Determination of the transaction price The transaction price is determined based on the consideration to which we will be entitled to receive in exchange for transferring goods or services to our customer. We estimate any variable consideration included in the transaction price using the expected value method that requires the use of significant estimates for discounts, cancellation periods, refunds and returns. Variable consideration is described in detail below. Allocation of the transaction price to the performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative Stand-Alone Selling Price (“SSP,”) basis. We determine SSP based on the price at which the performance obligation would be sold separately. If the SSP is not observable, we estimate the SSP based on available information, including market conditions and any applicable internally approved pricing guidelines. Recognition of revenue when, or as, we satisfy a performance obligation We recognize contract revenue over time and product revenue at a point in time, when the related performance obligation is satisfied by transferring the promised goods or services to our customer. Contract revenue is recognized based on a cost-to-cost input method. Disaggregation of Revenue For the three months ended March 31, 2020 and 2019, total sales in the United States represent approximately 85% and 90% of total consolidated revenues, respectively. Sales to Italy represented 13% and less than 10% of consolidated revenues in the three months ended March 31, 2020 and 2019, respectively. No other geographical area accounted for more than 10% of total sales during the three months ended March 31, 2020 and 2019. Principal versus Agent Considerations When another party is involved in providing goods or services to our customer, we apply the principal versus agent guidance in ASC Topic 606 to determine if we are the principal or an agent to the transaction. When we control the specified goods or services before they are transferred to our customer, we report revenue gross, as principal. If we do not control the goods or services before they are transferred to our customer, revenue is reported net of the fees paid to the other party, as agent. Our evaluation to determine if we control the goods or services within ASC Topic 606 includes the following indicators: We are primarily responsible for fulfilling the promise to provide the specified good or service. When we are primarily responsible for providing the goods and services, such as when the other party is acting on our behalf, we have indication that we are the principal to the transaction. We consider if we may terminate our relationship with the other party at any time without penalty or without permission from our customer. We have inventory risk before the specified good or service has been transferred to a customer or after transfer of control to the customer. We may commit to obtaining the services of another party with or without an existing contract with our customer. In these situations, we have risk of loss as principal for any amount due to the other party regardless of the amount(s) we earn as revenue from our customer. The entity has discretion in establishing the price for the specified good or service. We have discretion in establishing the price our customer pays for the specified goods or services. Contract Assets We capitalize costs and estimated earnings in excess of billings as a contract asset in current assets. At March 31, 2020 and 2019, contract assets totaled $0 and $16,486, respectively. Contract Liabilities Contract liabilities consist of customer advance payments and billings in excess of revenue recognized. We may receive payments from our customers in advance of completing our performance obligations. We record contract liabilities equal to the amount of payments received in excess of revenue recognized, Contract liabilities are recorded under the caption “contract liabilities” and are reported as current liabilities on our consolidated financial statements when the time to fulfill the performance obligations under terms of our contracts is less than one year. At March 31, 2020 and 2019, contract liabilities totaled $93,369 and $162,123, respectively. Cost of Sales Cost of sales includes inventory costs, materials and supplies costs, internal labor and related benefits, subcontractor costs, depreciation, overhead and shipping and handling costs incurred. Shipping and Handling Costs Shipping and handling costs incurred relating to the purchase of inventory are included in inventory which is charged to cost of sales as product are sold. Shipping and handling costs incurred for product shipped to customers are included in cost of sales. For the three months ended March 31, 2020 and 2019 shipping and handling costs amounted to $37,611 and $16,521, respectively. Research and Development Research and development costs incurred in the development of the Company’s products and under other Company sponsored research and development projects are expensed as incurred. Costs such as direct labor, direct costs, and other allocated costs incurred to perform research and development service pursuant to government and private research projects are in included in cost of sales. Research and development costs incurred in the development of the Company’s products for the three months ended March 31, 2020 and 2019 were $16,652 and $15,805, respectively, and are included in operating expenses on the accompanying unaudited consolidated statements of operations. Advertising Costs The Company participates in various advertising programs. All costs related to advertising of the Company’s products are expensed in the period incurred. Advertising costs charged to operations for the three months ended March 31, 2020 and 2019 were $2,594 and $146, respectively, and are included in selling and marketing on the unaudited consolidated accompanying statements of operations. These costs are included in sales and marketing on the consolidated accompanying statements of operations. These advertising expenses do not include cooperative advertising and sales incentives which have been deducted from sales. Federal and State Income Taxes The Company accounts for income tax using the liability method prescribed by ASC 740, “Income Taxes”. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the year in which the differences are expected to reverse. The Company records a valuation allowance to offset deferred tax assets if based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized as income or loss in the period that includes the enactment date. The Company follows the accounting guidance for uncertainty in income taxes using the provisions of ASC 740 “Income Taxes Stock-Based Compensation Stock-based compensation is accounted for based on the requirements of the Share-Based Payment Topic of ASC 718 which requires recognition in the financial statements of the cost of employee and director services received in exchange for an award of equity instruments over the period the employee or director is required to perform the services in exchange for the award (presumptively, the vesting period). The ASC also requires measurement of the cost of employee and director services received in exchange for an award based on the grant-date fair value of the award. The Company adopted ASU No. 2017-09 in 2018; its adoption did not have a material impact on its consolidated financial statements. Pursuant to ASC Topic 505-50, for share-based payments to consultants and other third-parties, compensation expense is determined at the “measurement date.” The expense is recognized over the service period of the award. Until the measurement date is reached, the total amount of compensation expense remains uncertain. The Company initially records compensation expense based on the fair value of the award at the reporting date. Loss Per Share of Common Stock ASC 260 “Earnings Per Share”, requires dual presentation of basic and diluted earnings per share (“EPS”) with a reconciliation of the numerator and denominator of the basic EPS computation to the numerator and denominator of the diluted EPS computation. Basic EPS excludes dilution. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted average number of shares of common shares outstanding during the period. Diluted net loss per common share is computed by dividing net loss by the weighted average number of shares of common stock, common stock equivalents and potentially dilutive securities outstanding during each period. Potentially dilutive common shares consist of common stock options and warrants (using the treasury stock method). These common stock equivalents may be dilutive in the future . March 31, 2020 December 31, 2019 Stock options 554,859 455,502 Stock warrants 4,052,715 2,817,463 Total 4,607,574 3,272,952 Additionally, there are an unknown quantity of common stock equivalents that result from a potential conversion of stock appreciation rights (See Note 14). Net loss per share for common stock is as follows: Net (loss) income per common shares outstanding: Three Months Ended March 31, 2020 Three Months Ended Class A common stock $ (0.06 ) $ (0.02 ) Weighted average shares outstanding: Class A common stock 6,501,345 3,978,173 Total weighted average shares outstanding 6,501,345 3,978,173 Segment Reporting The Company uses “the management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. The Company’s chief operating decision maker is the President of the Company, who reviews operating results to make decisions about allocating resources and assessing performance for the entire Company. The Company classified the reportable operating segments into (i) the development, manufacture and sale of consumer and institutional products using nanotechnology to deliver unique performance attributes at the surfaces of a wide variety of substrates (the “Product segment”) and (ii) nanotechnology design and development services for our future products and for government and private entities (the “Contract services segment”). Leases The Company adopted ASC 842 on January 1, 2019 using the modified retrospective basis and did not adjust comparative periods as permitted under Accounting Standards Update (“ASU”) 2018-11. ASC 842 supersedes nearly all existing lease accounting guidance under U.S. GAAP issued by the Financial Accounting Standards Board (“FASB”) including ASC Topic 840, Leases. ASC 842 requires that lessees recognize Right-of-Use (ROU) assets and lease liabilities calculated based on the present value of lease payments for all lease agreements with terms that are greater than twelve months. ASC 842 distinguishes leases as either a finance lease or an operating lease that affects how the leases are measured and presented in the statement of operations and statement of cash flows. For operating leases, we calculated ROU assets and lease liabilities based on the present value of the remaining lease payments as of the date of adoption using the IBR as of that date. On the date of adoption, operating lease liabilities and right-of-use assets totaled $400,327. We do not have finance leases as per the definition of ASC 842 as of March 31, 2019. The FASB issued practical expedients and accounting policy elections that the Company has applied as described below. Practical Expedients ASC 842 provides a package of three practical expedients that must be adopted together and applied to all lease agreements. The Company elected the package of practical expedients as follows for all leases: Whether expired or existing contracts contain leases under the new definition of a lease. Because the accounting for operating leases and service contracts was similar under ASC 840, there was no accounting reason to separate lease agreements from service contracts in order to account for them correctly. The Company reviewed existing service contracts to determine if the agreement contained an embedded lease to be accounted for on the balance sheet under ASC 842. Lease classification for expired or existing leases. Leases that were capital leases under ASC 840 are accounted for as financing leases under ASC 842 while leases that were operating leases under ASC 840 are accounted for as operating leases under ASC 842. Whether previously capitalized initial direct costs would meet the definition of initial direct costs under the new standard guidance. The definition of initial direct costs is more restrictive under ASC 842 than under ASC 840. Entities that do not elect the practical expedient are required to reassess capitalized initial direct costs under ASC 840 and record an equity adjustment for those that are not capitalizable under ASC 842. Accounting Policy Elections Lease Term The Company calculates the term for each lease agreement to include the noncancelable period specified in the agreement together with (1) the periods covered by options to extend the lease if the Company is reasonably certain to exercise that option, (2) periods covered by an option to terminate if the Company is reasonably certain not to exercise that option and (3) period covered by an option to extend (or not terminate) if controlled by the lessor. The assessment of whether the Company is reasonably certain to exercise an option to extend a lease requires significant judgement surrounding contract-based factors, asset-based factors, entity-based factors and market-based factors. Lease Payments Lease payments consist of the following payments (as applicable) related to the use of the underlying asset during the lease term: ● Fixed payments, including in substance fixed payments, less any lease incentives paid or payable to the lessee ● Variable lease payments that depend on an index or a rate, such as the Consumer Price Index or a market interest rate, initially measured using the index or rate at the commencement date of January 1, 2019. ● The exercise price of an option to purchase the underlying asset if the lessee is reasonably certain to exercise that option. ● Payments for penalties for terminating the lease if the lease term reflects the lessee exercising an option to terminate the lease. ● Fees paid by the lessee to the owners of a special-purpose entity for structuring the transaction ● For a lessee only, amounts probable of being owed by the lessee under residual value guarantees Incremental Borrowing Rate The ROU asset and related lease liabilities recorded under ASC 842 are calculated based on the present value of the lease payments using (1) the rate implicit in the lease or (2) the lessee’s IBR, defined as the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Recently Issued Accounting Pronouncements Financial Instruments — Credit Losses (Topic 326) In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Measurement of expected credit losses is to be based on relevant forecasts that affect collectability. The scope of financial assets within the CECL methodology is broad and includes trade receivables from certain revenue transactions and certain off-balance sheet credit exposures. Different components of the guidance require modified retrospective or prospective adoption. ASU 2016-13 is effective for the annual reporting period beginning on or after December 15, 2020. The Company adopted this standard January 1, 2020 and there was no material impact. Except for our accounting policies for allowance for doubtful accounts as a result of adopting ASU 2016-13, there have been no changes to our significant accounting policies described in Note 2 to our Annual Report on Form 10-K for the year ended December 31, 2019, that have had a material impact on our Consolidated Financial Statements and related notes. Reclassifications Certain accounts and financial statement captions in the prior periods have been reclassified to conform to the current period financial statements. |
