 inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.Level 2 – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.Level 3 – Unobservable inputs in which little or no market data exists, therefore requiring us to develop our own assumptions.Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. For equity securities traded on foreign exchanges, fair values are determined based on quoted market prices in the applicable foreign markets and are remeasured into U.S. dollars using exchange rates in effect at each balance sheet date in accordance with ASC Topic 830, Foreign Currency Matters. The use of different assumptions, exchange rates, and/or estimation methodologies may have a material effect on estimated fair values. Accordingly, the fair value estimates disclosed, or amounts recorded, may not be indicative of the amount that we or holders of the instruments could realize in a current market exchange.
