Summary of Significant Accounting Policies

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 

a. Nature of Business

 

Microwave Filter Company, Inc. (MFC) operates primarily in the United States and principally in one industry. The Company extends credit to business customers based upon ongoing credit evaluations. Microwave Filter Company, Inc. designs, develops, manufactures and sells electronic filters, both for radio and microwave frequencies, to help process signal distribution and to prevent unwanted signals from disrupting transmit or receive operations. Markets served include cable television, television and radio broadcast, satellite broadcast, mobile radio, commercial communications and defense electronics.

 

b. Basis of Consolidation

 

The consolidated financial statements include the accounts of Microwave Filter Company, Inc. (MFC) and its wholly-owned subsidiaries, Niagara Scientific, Inc. (NSI) and Microwave Filter International, LTD. (MFI) (dormant); located in Syracuse, New York. All significant intercompany balances and transactions have been eliminated in consolidation.

 

c. Revenue Recognition

 

Revenues from product sales are recorded as the products are shipped and title and risk of loss have passed to the customer, provided that no significant vendor or post-contract support obligations remain and the collection of the related receivable is probable. Billings in advance of the Company’s performance of such work are reflected as customer deposits in the accompanying consolidated balance sheet.

 

d. Cash and Cash Equivalents

 

The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and accounts receivable. Cash and cash equivalents consist of cash in banks and money market funds. The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company’s cash is held at federally insured institutions and balances may periodically exceed insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk with respect to cash. The Company also routinely assesses the financial strength of its customers and, as a consequence, believes that its trade accounts receivable credit risk exposure is limited.

 

e. Trade Accounts Receivable and Allowance for Doubtful Accounts

 

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company reviews its allowance for doubtful accounts monthly. Past due balances are reviewed individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers.

 

f. Inventories and Reserve for Obsolescence

 

Inventories are stated at the lower of cost determined on the first-in, first-out method or net realizable value.

 

Net realizable value is determined as the estimated selling price in the normal course of business minus the cost of completion, disposal and transportation.

 

The Company records a reserve for obsolete or excess inventory. The Company considers inventory quantities greater than a three year supply based on current year activity as well as any additional specifically identified inventory to be excess. The Company also provides for the total value of inventories that are determined to be obsolete based on criteria such as customer demand and changing technologies.

 

g. Research and Development

 

Costs in connection with research and development, which amount to $334,851 and $326,965 for the fiscal years 2018 and 2017, respectively, are charged to operations as incurred.

 

h. Property, Plant and Equipment

 

Property, plant and equipment are recorded at cost. Depreciation is provided using the straight-line method over the estimated useful lives of the respective assets. Buildings and building improvements are depreciated over an estimated service life of 10 to 30 years. Machinery and equipment are depreciated over an estimated useful life of 3 to 10 years. Office equipment and fixtures are depreciated over an estimated useful life of 3 to 10 years. At the time of sale or retirement, the cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recognized in income.

 

i. Income Taxes

 

The Company accounts for income taxes under FASB ASC 740-10. Deferred tax assets and liabilities are based on the difference between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates which are anticipated to be in effect when these differences reverse. The deferred tax provision is the result of the net change in the deferred tax assets and liabilities. A valuation allowance is established when it is necessary to reduce deferred tax assets to amounts expected to be realized. The Company has provided a full valuation allowance against its deferred tax assets.

 

The Company follows FASB ASC 740-10, which clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements and prescribes a recognition threshold and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on a tax return. Additionally, it provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company will include interest on income tax liabilities in interest expense and penalties in operations if such amounts arise. The Company determined it has no uncertain tax positions and therefore no amounts are recorded.

 

j. Earnings Per Share

 

The Company presents basic earnings per share (“EPS”), computed based on the weighted average number of common shares outstanding for the period, and when applicable diluted EPS, which gives the effect to all dilutive potential shares outstanding (i.e. options) during the period after restatement for any stock dividends. There were no dividends declared during the fiscal year ended September 30, 2018 and 2017. Loss used in the EPS calculation is net loss for each year. There were no dilutive potential shares outstanding for the years ended September 30, 2018 and 2017.

 

k. Fair Value of Financial Instruments

 

The carrying value of the Company cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturity of those instruments. The carrying value of the Company’s note payable approximates its fair value.

 

The Company currently does not trade in or utilize derivative financial instruments.

 

l. Miscellaneous Non-operating Income

 

Miscellaneous non-operating income generally consists of sales of scrap material and the forfeiture of non-refundable deposits and other incidental items.

 

m. Use of Estimates

 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 financial statements. Estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

 

n. Warranty Costs

 

The Company established a warranty reserve which provides for the estimated cost of product returns based upon historical experience and any known conditions or circumstances. Our warranty obligation is affected by product that does not meet specifications and performance requirements and any related costs of addressing such matters. Warranty costs were approximately $5,000 for the fiscal years ended September 30, 2018 and 2017, respectively.

 

o. Impairment of Long-Lived Assets

 

The carrying values of long-lived assets other than goodwill are generally evaluated for impairment only if events or changes in facts and circumstances indicate that carrying values may not be recoverable. Any impairment determined would be recorded in the current period and would be measured by comparing the fair value of the related asset to its carrying value. Fair value is generally determined by identifying estimated undiscounted cash flows to be generated by those assets. No impairments have been recorded for the fiscal years ended September 30, 2018 and 2017.

 

p. New Accounting Pronouncements

 

In February 2016, the FASB issued FASB ASU No. 2016-02, Leases (Topic 842). The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. For operating leases, a lessee is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the effect that the adoption of this ASU will have on its financial statements.

The components of the provision for income taxes in the accompanying consolidated statements of operations are as follows:

 

    Year Ended September 30,  
    2018     2017  
Currently payable:                
Federal   $ 0     $ 0  
State     50       0  
Deferred (credit)     0       0  
                 
    $ 50     $ 0  

 

The components of the provision for income taxes differs from the amount that would result from applying the federal statutory rate for the periods ended September 30, 2018 and 2017 is as follows:

 

    Year ended September 30,  
    2018     2017  
    Amount     %     Amount     %  
Statutory tax rate   $ 8,797       24.2 %   $ (89,833 )     (34.0 )%

    $ 0       0.0 %   $ 0       0.0 %

 

The temporary differences which give rise to deferred tax assets and (liabilities) at September 30 are as follows:

 

    2018     2017  
             
Inventory   $ 101,398     $ 157,515  
Accrued warranty     2,625       4,250  
Accrued vacation     15,004       26,347  
Accounts receivable     885       1,432  
Accelerated depreciation     22,477       27,320  
Research and development tax credit carryforward     305,357       288,369  
AMT credit carryforward     37,521       37,521  
NOL carryforward     232,389       268,666  
Valuation allowance     (717,656 )     (811,420 )
                 
Net deferred tax assets   $ 0     $ 0  

 

During December 2017, the Tax Cuts and Jobs Act (the “ACT”) was signed into law reducing the Federal corporate income tax rate from 34 percent to 21 percent. Based on the provisions of the ACT, the Company remeasured their net deferred tax assets applying the lower income tax rates to the Company’s net deferred tax assets. In addition, in accordance with the applicable Internal Revenue Code, the Company is required to calculate its current tax provision for fiscal 2018 using a blended corporate tax rate, resulting in a reduction in the effective current tax rate from 34.00 percent to 24.25 percent. The Company has provided a full valuation allowance against its net deferred tax assets. Accordingly, no impact arising from the change in the tax rates arising from the provisions of the ACT is reflected in these consolidated financial statements.

 

As required by FASB ASC 740 the Company has evaluated the positive and negative evidence bearing upon the realization of its net deferred tax assets. The Company has determined that, at this time, it is more likely than not that the Company will not realize all of the benefits of federal and state net deferred tax assets, and, as a result, a valuation allowance was established. The research and development tax credit carryforwards and NOL carryforwards generated through September 30, 2017, of approximately $300,000 and $800,000 expire at various times through 2037. Pursuant to the ACT, any of the Company’s newly-generated Federal NOL carryforwards can be carried forward indefinitely, while being limited to 80% of taxable income (determined without regard to the deduction.) As of September 30, 2018, the Company’s Federal AMT credit carryforward of approximately $35,000 is refundable in any year prior to 2022, in an amount equal to 50% (100% for tax years beginning in 2021) of the excess minimum tax credit for the tax year, over the amount of the credit allowable for the year against the regular tax liability. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service for the fiscal years September 30, 2016 through September 30, 2018. The Company has no uncertain tax positions. As of September 30, 2018 and 2017 there is no accrual for interest or penalties related to uncertain tax positions.

Nature of Business

a. Nature of Business

 

Microwave Filter Company, Inc. (MFC) operates primarily in the United States and principally in one industry. The Company extends credit to business customers based upon ongoing credit evaluations. Microwave Filter Company, Inc. designs, develops, manufactures and sells electronic filters, both for radio and microwave frequencies, to help process signal distribution and to prevent unwanted signals from disrupting transmit or receive operations. Markets served include cable television, television and radio broadcast, satellite broadcast, mobile radio, commercial communications and defense electronics.

( custom:NatureOfBusinessPolicyTextBock [Extension] )  
Basis of Consolidation

b. Basis of Consolidation

 

The consolidated financial statements include the accounts of Microwave Filter Company, Inc. (MFC) and its wholly-owned subsidiaries, Niagara Scientific, Inc. (NSI) and Microwave Filter International, LTD. (MFI) (dormant); located in Syracuse, New York. All significant intercompany balances and transactions have been eliminated in consolidation.

( us-gaap:ConsolidationPolicyTextBlock )  
Revenue Recognition

c. Revenue Recognition

 

Revenues from product sales are recorded as the products are shipped and title and risk of loss have passed to the customer, provided that no significant vendor or post-contract support obligations remain and the collection of the related receivable is probable. Billings in advance of the Company’s performance of such work are reflected as customer deposits in the accompanying consolidated balance sheet.

( us-gaap:RevenueRecognitionPolicyTextBlock )  
Cash and Cash Equivalents

d. Cash and Cash Equivalents

 

The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and accounts receivable. Cash and cash equivalents consist of cash in banks and money market funds. The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company’s cash is held at federally insured institutions and balances may periodically exceed insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk with respect to cash. The Company also routinely assesses the financial strength of its customers and, as a consequence, believes that its trade accounts receivable credit risk exposure is limited.

( us-gaap:CashAndCashEquivalentsPolicyTextBlock )  
Trade Accounts Receivable and Allowance for Doubtful Accounts

e. Trade Accounts Receivable and Allowance for Doubtful Accounts

 

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company reviews its allowance for doubtful accounts monthly. Past due balances are reviewed individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers.

( us-gaap:ReceivablesTradeAndOtherAccountsReceivableAllowanceForDoubtfulAccountsPolicy )  
Inventories and Reserve for Obsolescence

f. Inventories and Reserve for Obsolescence

 

Inventories are stated at the lower of cost determined on the first-in, first-out method or net realizable value.

 

Net realizable value is determined as the estimated selling price in the normal course of business minus the cost of completion, disposal and transportation.

 

The Company records a reserve for obsolete or excess inventory. The Company considers inventory quantities greater than a three year supply based on current year activity as well as any additional specifically identified inventory to be excess. The Company also provides for the total value of inventories that are determined to be obsolete based on criteria such as customer demand and changing technologies.

( us-gaap:InventoryPolicyTextBlock )  
Research and Development

g. Research and Development

 

Costs in connection with research and development, which amount to $334,851 and $326,965 for the fiscal years 2018 and 2017, respectively, are charged to operations as incurred.

( us-gaap:ResearchAndDevelopmentExpensePolicy )  
Property, Plant and Equipment

h. Property, Plant and Equipment

 

Property, plant and equipment are recorded at cost. Depreciation is provided using the straight-line method over the estimated useful lives of the respective assets. Buildings and building improvements are depreciated over an estimated service life of 10 to 30 years. Machinery and equipment are depreciated over an estimated useful life of 3 to 10 years. Office equipment and fixtures are depreciated over an estimated useful life of 3 to 10 years. At the time of sale or retirement, the cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recognized in income.

( us-gaap:PropertyPlantAndEquipmentPolicyTextBlock )  
Income Taxes

i. Income Taxes

 

The Company accounts for income taxes under FASB ASC 740-10. Deferred tax assets and liabilities are based on the difference between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates which are anticipated to be in effect when these differences reverse. The deferred tax provision is the result of the net change in the deferred tax assets and liabilities. A valuation allowance is established when it is necessary to reduce deferred tax assets to amounts expected to be realized. The Company has provided a full valuation allowance against its deferred tax assets.

 

The Company follows FASB ASC 740-10, which clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements and prescribes a recognition threshold and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on a tax return. Additionally, it provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company will include interest on income tax liabilities in interest expense and penalties in operations if such amounts arise. The Company determined it has no uncertain tax positions and therefore no amounts are recorded.

( us-gaap:IncomeTaxPolicyTextBlock )  
Earnings Per Share

j. Earnings Per Share

 

The Company presents basic earnings per share (“EPS”), computed based on the weighted average number of common shares outstanding for the period, and when applicable diluted EPS, which gives the effect to all dilutive potential shares outstanding (i.e. options) during the period after restatement for any stock dividends. There were no dividends declared during the fiscal year ended September 30, 2018 and 2017. Loss used in the EPS calculation is net loss for each year. There were no dilutive potential shares outstanding for the years ended September 30, 2018 and 2017.

( us-gaap:EarningsPerSharePolicyTextBlock )  
Fair Value of Financial Instruments

k. Fair Value of Financial Instruments

 

The carrying value of the Company cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturity of those instruments. The carrying value of the Company’s note payable approximates its fair value.

 

The Company currently does not trade in or utilize derivative financial instruments.

( us-gaap:FairValueOfFinancialInstrumentsPolicy )  
Miscellaneous Non-operating Income

l. Miscellaneous Non-operating Income

 

Miscellaneous non-operating income generally consists of sales of scrap material and the forfeiture of non-refundable deposits and other incidental items.

( custom:MiscellaneousNonoperatingIncomePolicyTextBlock [Extension] )  
Use of Estimates

m. Use of Estimates

 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 financial statements. Estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

( us-gaap:UseOfEstimates )  
Warranty Costs

n. Warranty Costs

 

The Company established a warranty reserve which provides for the estimated cost of product returns based upon historical experience and any known conditions or circumstances. Our warranty obligation is affected by product that does not meet specifications and performance requirements and any related costs of addressing such matters. Warranty costs were approximately $5,000 for the fiscal years ended September 30, 2018 and 2017, respectively.

( us-gaap:StandardProductWarrantyPolicy )  
Impairment of Long-Lived Assets

o. Impairment of Long-Lived Assets

 

The carrying values of long-lived assets other than goodwill are generally evaluated for impairment only if events or changes in facts and circumstances indicate that carrying values may not be recoverable. Any impairment determined would be recorded in the current period and would be measured by comparing the fair value of the related asset to its carrying value. Fair value is generally determined by identifying estimated undiscounted cash flows to be generated by those assets. No impairments have been recorded for the fiscal years ended September 30, 2018 and 2017.

( us-gaap:ImpairmentOrDisposalOfLongLivedAssetsPolicyTextBlock )  
New Accounting Pronouncements

p. New Accounting Pronouncements

 

In February 2016, the FASB issued FASB ASU No. 2016-02, Leases (Topic 842). The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. For operating leases, a lessee is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the effect that the adoption of this ASU will have on its financial statements.
