Fair Value Measurements |
Fair Value Measurements | Note 5 — Fair Value Measurements ​ Current accounting guidance defines fair value as the price that would be received on the sale of an asset, or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Guidance requires disclosure of the extent to which fair value is used to measure financial assets and liabilities, the inputs utilized in calculating valuation measurements, and the effect of the measurement of significant unobservable inputs on earnings, or changes in net assets, as of the measurement date. Guidance establishes a three-level valuation hierarchy based upon the transparency of inputs utilized in the measurement and valuation of financial assets or liabilities as of the measurement date. Level 1 inputs include quoted prices for identical instruments and are the most observable. Level 2 inputs include quoted prices for similar assets and observable inputs such as interest rates, foreign currency exchange rates, commodity rates and yield curves. Level 3 inputs are not observable in the market and include management’s own judgments about the assumptions market participants would use in pricing the asset or liability. The use of observable and unobservable inputs is reflected in the hierarchy assessment disclosed in the table below. ​ As of September 30, 2019, December 31, 2018 and September 30, 2018, the Company held certain financial assets that are required to be measured at fair value on a recurring basis. These included derivative hedging instruments related to the purchase of certain raw materials and foreign currencies, investments in trading securities and available for sale securities. The Company’s available for sale securities principally consist of municipal bonds and variable rate demand notes. ​ ​ ​ The following table presents information about the Company’s financial assets and liabilities measured at fair value as of September 30, 2019, December 31, 2018 and September 30, 2018 and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value: ​
