4. FINANCIAL INSTRUMENTS

ASC 820, "Fair Value Measurements", requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

ASC 820 prioritizes the inputs into three levels that may be used to measure fair value:

Level 1	applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2	applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3	applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

The Company's financial instruments consist principally of cash, cash equivalents, marketable securities, trade accounts receivable, accounts payable and accrued liabilities. Pursuant to ASC 820, the fair value of our cash equivalents and marketable securities is determined based on "Level 1" inputs, which consist of quoted prices in active markets for identical assets. The Company believes that the recorded values of all of the other financial instruments approximate their current fair values because of their nature and respective maturity dates or durations.
