The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates.

Sales are recorded as shipments are made based upon contract prices. Any losses anticipated on fixed price contracts are provided for currently. Sales are recorded net of sales returns, allowances and discounts.

The Company recognizes sales in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Subtopic 605-10-S99, Revenue Recognition (ASC 605-10-S99). ASC 605-10-S99 requires that four basic criteria must be met before sales can be recognized: (1) persuasive evidence of an arrangement exists; (2) shipment has occurred or services have been rendered; (3) the fee is fixed and determinable; and (4) collectibility is reasonably assured.

Deferred revenue represents prepayments from customers and will be recognized as sales when the products are shipped per the terms of the contract.

The Company has $2,008,000 in short term investments at May 31, 2014. Short-term investments consist of certificates of deposits with initial maturities greater than 90 days. These investments are reported at historical cost, which approximates fair value. All highly liquid investments with initial maturities of 90 days or less are classified as cash equivalents. All short-term investments are securities which the Company has the ability and intent to hold to maturity and mature within one year.

Inventories are stated at lower of cost or market value and include material, labor and manufacturing overhead. All inventories are valued using the FIFO (first-in, first-out) method of inventory valuation. The Company determines the need to write inventory down below its cost via an analysis based on the usage of inventory over a three year period and projected usage based on current backlog.

The Company accounts for income taxes using the asset and liability method. Under this method the Company records deferred income taxes for the temporary differences between the financial reporting basis and the tax basis of assets and liabilities at enacted tax rates expected to be in effect when such amounts are realized or settled. The resulting deferred tax liabilities and assets are adjusted to reflect changes in tax law or rates in the period that includes the enactment date.

Property, plant, and equipment are carried at cost, and depreciation is provided using the straight-line method at rates based upon the following estimated useful lives (in years) of the assets:

Buildings	15
Facility improvements	8-15
Machinery and equipment	5-10
Furniture and fixtures	5-8

The Company assesses long-lived assets for impairment under ASC 360-10-35, Property, Plant and Equipment – Subsequent Measurement. When events or circumstances indicate that an asset may be impaired, an assessment is performed. The estimated future undiscounted cash flows associated with the asset are compared to the asset’s net book value to determine if a write down to market value less cost to sell is required.

Repairs and maintenance are expensed as incurred. Improvements which extend the useful life of property, plant, and equipment are capitalized.

Costs for the design and development of new products and processes are expensed as incurred.
