NOTE 8 - FAIR VALUE MEASUREMENTS

The following represents the assets and liabilities measured at fair value:

Financial assets classified in Level 1 included money market funds. The valuation of these instruments is based upon unadjusted quoted prices for identical assets in active markets.

The valuation of financial assets and liabilities classified in Level 2 is determined using a market approach based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable. Level 2 assets include commercial paper, certificates of deposit and commodity hedge contracts. Level 2 liabilities include commodity hedge contracts.

The Level 3 assets and liabilities include derivative assets that consist of freestanding derivative instruments related to a certain supply agreement and derivative assets and liabilities related to certain provisional pricing arrangements with our customers.

The supply agreement included in our Level 3 assets contains provisions for supplemental revenue or refunds based on the average annual daily market price for hot-rolled coil steel in the year the iron ore product is consumed in the customer’s blast furnaces. We account for these provisions as derivative instruments at the time of sale and adjust the derivative instruments to fair value through Product revenues each reporting period until the product is consumed and the amounts are settled. We had assets of $106.4 million and $89.3 million at March 31, 2019 and December 31, 2018, respectively, related to this supply agreement.

The provisional pricing arrangements included in our Level 3 assets/liabilities specify provisional price calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate to be based on market inputs at a specified point in time in the future, per the terms of the supply agreements. The difference between the estimated final revenue rate at the date of sale and the estimated final revenue rate at the measurement date is characterized as a derivative and is required to be accounted for separately once the revenue has been recognized. The derivative instruments are adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the final revenue rates are determined. We had assets of $0.3 million and liabilities of $9.8 million related to provisional pricing arrangements at March 31, 2019 compared to assets of $2.1 million related to provisional pricing arrangements at December 31, 2018.

The following table illustrates information about quantitative inputs and assumptions for the assets and liabilities categorized in Level 3 of the fair value hierarchy:

The significant unobservable input used in the fair value measurement of our customer supply agreement is a forward-looking estimate of the average annual daily market price for hot-rolled coil steel determined by management.

The significant unobservable inputs used in the fair value measurement of our provisional pricing arrangements include estimates for PPI data and management’s estimate of Platts 62% Price based upon current market data and index pricing, which include forward-looking estimates determined by management.

The carrying values of certain financial instruments (e.g., Accounts receivable, net, Accounts payable and Other current liabilities) approximates fair value and, therefore, have been excluded from the table below. A summary of the carrying value and fair value of other financial instruments were as follows:
