Summary of Significant Accounting Policies (Policies)

12 Months Ended

Jun. 30, 2016

Use of Estimates, Policy [Policy Text Block]

Use of estimates

The policies utilized by the Company in the preparation of the financial statements conform to accounting principles generally accepted in the United States of America, and require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates.

Revenue Recognition, Policy [Policy Text Block]

Revenue recognition

Revenue is recognized for all sales, including sales to agents and distributors, at the time products are shipped and title has transferred, provided that a purchase order has been received or a contract executed, there are not uncertainties regarding customer acceptance, the sales price is fixed and determinable and collectability is reasonably assured. Sales discounts, returns and allowances are included in net sales, and the provision for doubtful accounts is included in selling, general and administrative expenses. Additionally, it is the Company’s practice to include revenues generated from freight billed to customers in net sales with corresponding freight expense included in cost of sales in the Statement of Operations. The Company reports sales taxes on sales transactions on a net basis in the Statement of Operations, and therefore does not include sales taxes in revenues or costs.

The sales price is fixed by Allied’s acceptance of the buyer’s firm purchase order. The sales price is not contingent, or subject to additional discounts. Allied’s standard shipment terms are “F.O.B. shipping point” as stated in Allied’s Terms and Conditions of Sale. The customer is responsible for obtaining insurance for and bears the risk of loss for product in-transit. Additionally, sales to customers do not include the right to return merchandise without the prior consent of Allied. In those cases where returns are accepted, product must be current and restocking fees must be paid by the respective customer. A provision has been made for estimated sales returns and allowances. These estimates are based on historical analysis of credit memo data and returns.

Allied does not provide installation services for its products. Most products shipped are ready for immediate use by the customer. The Company’s in-wall medical system components, central station pumps and compressors, and headwalls do require installation by the customer. These products are typically purchased by a third-party contractor who is ultimately responsible for installation services. Accordingly, the customer purchase order or contract does not require customer acceptance of the installation prior to completion of the sale transaction and revenue recognition. Allied’s standard payment terms are net 30 days from the date of shipment, and payment is specifically not subject to customer inspection or acceptance, as stated in Allied’s Terms and Conditions of Sale. The buyer becomes obligated to pay Allied at the time of shipment. Allied requires credit applications from its customers and performs credit reviews to determine the creditworthiness of new customers. Allied requires letters of credit, where warranted, for international transactions. Allied also protects its legal rights under mechanics lien laws when selling to contractors.

The Company offers limited warranties on its products. The standard warranty period is one year. The Company’s cost of providing warranty service for its products for the years ended June 30, 2016, June 30, 2015, and June 30, 2014 was $89,895, $176,169, and $113,209, respectively. The related liability for warranty service amounted to $100,000 and $130,000 at June 30, 2016 and 2015, respectively.

Advertising Costs, Policy [Policy Text Block]

Marketing and Advertising Costs

Promotional and advertising costs are expensed as incurred and are included in selling, general and administrative expenses in the Statement of Operations. Advertising expenses for the years ended June 30, 2016, 2015 and 2014 were $15,699, $32,675, and $17,904, respectively.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and cash equivalents

For purposes of the statement of cash flows, the Company considers all highly liquid investments with a maturity of three months or less when acquired to be cash equivalents.

The Company maintains funds in bank accounts that, at times, may exceed the limit insured by the Federal Deposit Insurance Corporation. The risk of loss attributable to these uninsured balances is mitigated by depositing funds only in high credit quality financial institutions. The Company has not experienced any losses in such accounts.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign currency transactions

Allied has international sales which are denominated in U.S. dollars, the functional currency for these transactions.

Accounts Receivable And Concentrations Of Credit Risk [Policy Text Block]

Accounts receivable and concentrations of credit risk

Accounts receivable are recorded at the invoiced amount. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company maintains reserves for potential credit losses based on past experience and an analysis of current amounts due, and historically such losses have been within management's expectations. The Company maintains an allowance for doubtful accounts to reflect the uncollectibility of accounts receivable based on past collection history and specific risks indentified among uncollected accounts. Accounts receivable are charged to the allowance for doubtful accounts when the Company determines that the receivable will not be collected and/or when the account has been referred to a third party collection agency. The Company’s customers can be grouped into three main categories: medical equipment distributors, construction contractors and health care institutions. At June 30, 2016, the Company believes that it has no significant concentration of credit risk.

Inventory, Policy [Policy Text Block]

Inventories

Inventories are stated at the lower of cost, determined using the last-in, first-out (“LIFO”) method, or market. If the first-in, first-out method (which approximates replacement cost) had been used in determining cost, inventories would have been $2,286,022 and $2,383,104 higher at June 30, 2016 and 2015, respectively. Changes in the LIFO reserve are included in cost of sales. Cost of sales was reduced by $86,698, $0, and $0 in fiscal 2016, 2015, and 2014 respectively, as a result of LIFO liquidations. Costs in inventory include raw materials, direct labor and manufacturing overhead.

Inventory is recorded net of a reserve for obsolete and excess inventory which is determined based on an analysis of inventory items with no usage in the preceding year and for inventory items for which there is greater than two years’ usage on hand. The reserve for obsolete and excess inventory was $1,498,915 and $1,472,956 at June 30, 2016 and 2015, respectively.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, plant and equipment

Property, plant and equipment are recorded at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, which range from 3 to 35 years. Expenditures for repairs, maintenance and renewals are charged to income as incurred. Expenditures, which improve an asset or extend its estimated useful life, are capitalized. When properties are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts and any gain or loss is included in income.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of long-lived assets

The Company evaluates impairment of long-lived assets under the provisions of ASC Topic 360: “Property, Plant and Equipment.” ASC 360 provides a single accounting model for long-lived assets to be disposed of and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Under ASC 360, if the sum of the expected future cash flows (undiscounted and without interest charges) of the long-lived assets is less than the carrying amount of such assets, an impairment loss will be recognized. No impairment losses of long-lived assets or identifiable intangibles were recorded by the Company for fiscal years ended June 30, 2016, 2015, and 2014.

Collective Bargaining Agreement [Policy Text Block]

Collective Bargaining Agreement

At June 30, 2016, the Company had approximately 236 full-time employees. Approximately 139 employees in the Company’s principal manufacturing facility located in St. Louis, Missouri, are covered by a collective bargaining agreement that will expire on May 31, 2018.

Self Insurance [Policy Text Block]

Self-insurance

The Company maintains a self-insurance program for a portion of its health care costs. Self-insurance costs are accrued based upon the aggregate of the liability for reported claims and the estimated liability for claims incurred but not reported. As of June 30, 2016 and 2015, the Company had $175,000 and $195,000 respectively, of accrued liabilities related to health care claims. In order to establish the self-insurance reserves, the Company utilized actuarial estimates of expected claims based on analyses of historical data.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair value of financial instruments

The Company’s financial instruments include cash, accounts receivable and accounts payable. The carrying amounts for cash, accounts receivable and accounts payable approximate their fair value due to the short maturity of these instruments.

Income Tax, Policy [Policy Text Block]

Income taxes

The Company accounts for income taxes under ASC Topic 740: “Income Taxes.” Under ASC 740, the deferred tax provision is determined using the liability method, whereby deferred tax assets and liabilities are recognized based upon temporary differences between the financial statement and income tax bases of assets and liabilities using presently enacted tax rates. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. In assessing the need for a valuation allowance the Company first considers the reversals of existing temporary deferred tax liabilities and available tax planning strategies. To the extent these items are not sufficient to cause the realization of deferred tax assets, the Company considers the availability of future taxable income to the extent such income is considered likely to occur based on the Company’s earnings history, current income trends and projections.

In light of its history of operating losses the Company does not rely on the existence of future taxable income as it currently cannot conclude future taxable income is likely to occur. The Company does rely on reversals of existing temporary deferred tax liabilities and tax planning strategies to the extent available to support the value of its existing deferred tax assets. As of June 30, 2014, the Company’s deferred tax assets exceeded the amount supportable through reversals of existing deferred tax liabilities and tax planning strategies causing a valuation allowance to be recorded against the excess deferred tax assets. Additions to the valuation allowance were recorded in 2015 and 2016 for the unrealizable value of deferred tax assets.

The Company recognizes tax liabilities when, despite the Company’s belief that its tax return positions are supportable, the Company believes that certain positions may not be fully sustained upon review by tax authorities. Benefits from tax positions are measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. To the extent the Company deems it necessary to record a liability for its tax positions, the current portion of the liability is included in income taxes payable and the noncurrent portion is included in other liabilities on the balance sheet. If upon the final tax outcome of these matters the ultimate liability is different than the amounts recorded, such differences are reflected in income tax expense in the period in which such determination is made. The Company files a federal and multiple state income tax returns. With few exceptions the Company’s federal and state income tax returns are open for fiscal years ending after June 30, 2013.

The Company classifies interest expenses on taxes payable as interest expense. Penalties are classified as a component of other expenses.

Research and Development Expense, Policy [Policy Text Block]

Research and development costs

Research and development costs are expensed as incurred and are included in selling, general and administrative expenses. Research and development expenses for the years ended June 30, 2016, 2015 and 2014 were $463,902, $528,285, and $657,356, respectively.

Earnings Per Share, Policy [Policy Text Block]

Earnings per share

Basic earnings per share are based on the weighted average number of shares of common stock outstanding during the year. Diluted earnings per share are based on the sum of the weighted average number of shares of common stock and common stock equivalents outstanding during the year. The weighted average number of basic and diluted shares outstanding for the years ended June 30, 2016, 2015 and 2014 was 8,027,147 shares. The dilutive effect of the Company's employee and director stock option plans are determined by use of the treasury stock method. There are no potential common shares excluded from the calculation of net loss per share, as their effect would be anti-dilutive for the years ended June 30, 2016, 2015 and 2014 respectively.

The following information is necessary to calculate earnings per share for the periods presented:

Year ended June 30,	2016		2015		2014

Net loss, as reported	$	(2,304,831)	$	(1,777,310)	$	(2,805,913)

Weighted average common shares outstanding		8,027,147		8,027,147		8,027,147
Effect of dilutive stock options		-		-		-
Weighted average diluted common shares outstanding		8,027,147		8,027,147		8,027,147

Net loss per common share
Basic	$	(0.29)	$	(0.22)	$	(0.35)
Diluted	$	(0.29)	$	(0.22)	$	(0.35)

Employee stock options excluded from computation of diluted income per share amounts because their effect would be anti-dilutive		-		-		-

Employee stock-based compensation

The company follows the provisions of ASC Topic 718: “Compensation – Stock Compensation”, which sets accounting requirements for “share-based” compensation to employees, including employee stock purchase plans, and requires companies to recognize in the statement of operations the grant-date fair value of the stock options and other equity-based compensation.

The fair value of options granted is estimated on the date of grant using the Black-Scholes option-pricing model. The following table summarizes the weighted average assumptions utilized in the Black-Scholes option pricing model for options granted during the fiscal years ended June 30, 2016, 2015 and 2014.

	2016			2015			2014

Weighted-average fair value	$	0.39		$	0.70		$	1.04
Weighted-average volatility		30	%		44	%		45	%
Weighted-average expected life (in years)		6.0			6.0			6.0
Weighted-average risk-free interest rate		1.91	%		1.85	%		1.68	%
Dividend yield		0	%		0	%		0	%

Expected volatility is based on the historical volatility of the Company’s common stock to estimate future volatility. The risk-free rates are taken from rates as published by the Federal Reserve and represent the yields on actively traded treasury securities for terms equal or approximately equal to the expected terms of the options. The expected term is calculated using the SEC Staff Accounting Bulletin 107 (ASC 718-10-S99) simplified method. The dividend yield is zero based on the fact that the Company has no intention of paying dividends in the near term.

Share-based compensation expense included in the Statement of Operations for the fiscal years ended June 30, 2016, 2015 and 2014 was approximately $3,000, $5,000 and $10,000, respectively. Unrecognized shared-based compensation cost related to unvested stock options as of June 30, 2016 amounts to approximately $1,000. The cost is expected to be recognized over the next fiscal year.

The Company recognized an income tax benefit for share-based compensation arrangements of approximately $4,000 for the year ended June 30, 2014. The income tax benefit for the years ended June 30, 2016 and 2015 of approximately $1,000 and $2,000, respectively, were fully offset by an increase in the deferred tax asset valuation allowance.

No stock options were exercised during fiscal years 2016, 2015 and 2014.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) No. 2014-09, “Revenue from Contracts with Customers.” This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This ASU is effective for annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. On July 9, 2015 the FASB voted to defer the effective date of this standard by one year to December 15, 2017 for the interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. Companies may use either a full retrospective or modified retrospective approach to adopt this ASU. We are currently evaluating which transition approach to use and the full impact this ASU will have on our future financial statements.

In August 2014, the FASB issued ASU No. 2014-15, to communicate amendments to FASB Account Standards Codification Subtopic 205-40, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” The ASU requires management to evaluate relevant conditions, events and certain management plans that are known or reasonably knowable as of the evaluation date when determining whether substantial doubt about an entity’s ability to continue as a going concern exists. Management will be required to make this evaluation for both annual and interim reporting periods. Management will have to make certain disclosures if it concludes that substantial doubt exists or when it plans to alleviate substantial doubt about the entity’s ability to continue as a going concern. The standard is effective for annual periods ending after December 15, 2016 and for interim reporting periods starting in 2017. Early adoption is permitted. We currently believe there will be no impact on our financial statement disclosures.

In April 2015, the FASB issued ASU No. 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs”. This ASU requires companies to present debt issuance costs as a direct deduction from the carrying value of that debt liability. ASU 2015-03 does not impact the recognition and measurement guidance for debt issuance costs. This ASU is effective for annual reporting periods beginning after December 15, 2015 and early adoption is permitted. Accordingly, we will adopt this ASU on July 1, 2016. Companies are required to use a retrospective approach and we currently believe there will be no impact on our financial statement disclosures.

In July 2015, the FASB issued ASU No. 2015-11 to simplify the subsequent measurement of inventory. Under this new standard, an entity should measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments in this guidance should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the impact to our future financial statements.

In November 2015, the FASB issued Accounting Standards Update No. 2015-17 (“ASU 2015-17”), Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The amendments in ASU 2015-17 seek to simplify the presentation of deferred income taxes and require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. ASU 2015-17 is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early application permitted for all entities as of the beginning of an interim or annual reporting period. The Company is in the process of evaluating the impact of this update on its financial statements.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which requires lessees to recognize assets and liabilities for leases with lease terms of more than 12 months and disclose key information about leasing arrangements. Consistent with current U.S. GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. The update is effective for reporting periods beginning after December 15, 2018. Early adoption is permitted. The Company is in the process of evaluating the impact of this update on its financial statements.

In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606) Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” (“ASU 2016-08”). ASU 2016-08 further clarifies principal and agent relationships within ASU 2014-09. Similar to ASU 2014-09, the effective date will be the first quarter of fiscal year 2018 with early adoption permitted in the first quarter of fiscal year 2017. The Company is evaluating the impact that adoption of this new standard will have on its financial statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 is intended to simplify several aspects of accounting for share-based payment awards. The effective date will be the first quarter of fiscal year 2018, with early adoption permitted. The Company is evaluating the impact that adoption of this new standard will have on its financial statements.

In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing” (“ASU 2016-10”). The amendments in ASU 2016-10 are expected to reduce the cost and complexity of applying the guidance on identifying promised goods or services in contracts with customers and to improve the operability and understandability of licensing implementation guidance related to the entity's intellectual property. Similar to ASU 2014-09, the effective date will be the first quarter of fiscal year 2018 with early adoption permitted in the first quarter of fiscal year 2017. The Company is evaluating the impact that adoption of this new standard will have on its financial statements.
