| Receivables | ' |
| Receivables |
|
| Receivables are carried at original invoice less estimates made for doubtful receivables. Management determines the allowances for doubtful accounts by reviewing and identifying troubled accounts on a periodic basis and by using historical experience applied to an aging of accounts. A receivable is considered to be past due if any portion of the receivable balance is outstanding for more than 30 days. Receivables are written off when deemed uncollectible. Recoveries of receivables previously written off are recorded when received. |
| Inventories | ' |
| Inventories |
|
| Inventories are valued at the lower of cost or market using the FIFO (first-in, first-out) method. |
| Depreciation and Amortization | ' |
| Depreciation and Amortization |
|
| Equipment and leasehold improvements are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Repairs and maintenance are charged to expense as incurred; renewals and betterments which significantly extend the useful lives of existing equipment are capitalized. Significant leasehold improvements are capitalized and amortized over the term of the lease; equipment is depreciated over three to ten years. |
| Prepaid Expenses | ' |
| Prepaid Expenses |
|

| Research and Development and Patents |
|
| Research and development expenditures are charged to operations as incurred. The costs of obtaining patents, primarily legal fees, are capitalized and once obtained, amortized over the life of the respective patent on the straight-line method. |
|
| Patents relate to products that have been developed and are being marketed by the Company. |
|
| Patents pending relate to products under development. The Company is developing certain compounds intended for use as bacteria growth retardant agents for use in food and other products. |
| Use of Estimates | ' |
| Use of Estimates |
|
| The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |
| Income Per Comon Share | ' |
| Income Per Common Share |
|
| Income per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. When dilutive, stock options are included as share equivalents using the treasury stock method in the calculation of diluted earnings per share. The Company has no outstanding options or other rights to acquire its unissued common shares. |
| Comprehensive Income | ' |
| Comprehensive Income |
|
| Components of comprehensive income include amounts that are included in the comprehensive income but are excluded from net income. During the quarters ending July 31, 2014 and 2013, there were no differences between the Company’s net income and comprehensive income. |
| Income Taxes | ' |
| Income Taxes |
|
| Income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due and deferred taxes related primarily to differences in the methods of accounting for patents, inventories, certain accrued expenses and bad debt expenses for financial and income tax reporting purposes. The deferred income taxes represent the future tax consequences of those differences, which will be taxable in the future. |
|
| The Company files tax returns in the U.S. federal jurisdiction and with the state of Illinois. Various tax years remain open to examinations although there are currently no ongoing tax examinations. Management’s policy is to recognize interest and penalties related to uncertain tax positions in income tax expense. |
|
| The provision (benefit) for income taxes consists of the following components as of July 31: |

| Provision (benefit) for Income Taxes | | $ | 4,992 | | | $ | (2,037 | ) |

| Recent Accounting Pronouncements | ' |
| Recent Accounting Pronouncements |
|
| The FASB issues ASUs to amend the authoritative literature in Accounting Standards Certification (ASC). There have been a number of ASUs to date that amend the original text of ASCs. Those ASUs issued to date either (i) provide supplemental guidance, (ii) are technical corrections, (iii) are not applicable to the Company or (iv) are not expected to have a significant impact on the Company. |
|
| In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. |
|
| The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements and have not yet determined the method by which we will adopt the standard as of May 1, 2017. |
