Fair Value Measurements [Abstract]
Fair Value Measurement, Policy [Policy Text Block]	FASB ASC 820, “Fair Value Measurements and Disclosures,” defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements. The Company applies the provisions of ASC 820 to all its assets and liabilities that are being measured and reported on a fair value basis. ASC 820 discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). ASC 820 enables readers of financial statements to assess the inputs used to develop those measurements by establishing a hierarchy, which prioritizes those inputs used, for ranking the quality and reliability of the information used to determine fair values. The standard requires that each asset and liability carried at fair value be classified into one of the following categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. The Company has an established process for determining fair value for its financial assets and liabilities, principally cash and cash equivalents and foreign currency exchange contracts. Fair value is based on quoted market prices, where available. If quoted market prices are not available, fair value is based on assumptions that use as inputs market-based parameters.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash equivalents. Included within “Cash and cash equivalents” are highly liquid investments in money market funds with various underlying securities all of which maintain AAA credit ratings. Also included within cash equivalents are our highly liquid investments in non-domestic bank term deposits. The Company uses quoted market prices to determine the fair value of these investments and they are classified in Level 1 of the fair value hierarchy. The carrying amounts approximate fair value because of the short maturity of the instruments.

Disclosure of accounting policy for cash and cash equivalents, including the policy for determining which items are treated as cash equivalents. Other information that may be disclosed includes (1) the nature of any restrictions on the entity's use of its cash and cash equivalents, (2) whether the entity's cash and cash equivalents are insured or expose the entity to credit risk, (3) the classification of any negative balance accounts (overdrafts), and (4) the carrying basis of cash equivalents (for example, at cost) and whether the carrying amount of cash equivalents approximates fair value.
