FINANCIAL INSTRUMENTS AND INVESTMENTS | FINANCIAL INSTRUMENTS AND INVESTMENTS The fair value of a financial instrument is the amount that could be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets are marked to bid prices and financial liabilities are marked to offer prices. Fair value measurements do not include transaction costs. A fair value hierarchy is used to prioritize the quality and reliability of the information used to determine fair values. Categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is divided into the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. Fair value estimates of financial instruments are made at a specific point in time, based on relevant information about financial markets and specific financial instruments. As these estimates are subjective in nature, involving uncertainties and matters of significant judgment, they cannot be determined with precision. Changes in assumptions can significantly affect estimated fair value. The carrying value of cash, accounts receivable, accounts payable and accrued liabilities approximate their fair value because of the short-term nature of these instruments. Investments are presented at fair value as of the balance sheet date and accumulated gains or losses on those investments are reported in other comprehensive income. Management is of the opinion that the Company is not exposed to significant interest or credit risks arising from financial instruments and any declines in the value of investments are temporary in nature.
