Our financial assets and liabilities are valued using market prices on both active markets (Level 1), less active markets (Level 2) and little or no market activity (Level 3). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments, identical instruments in less active markets, or models using market observable inputs. Level 3 instrument valuations typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. We did not have any transfers of financial instruments between valuation levels during the nine months ended September 30, 2018. The majority of our derivative instruments are valued using pricing models that take into account the contract terms as well as multiple inputs where applicable, such as equity prices, interest rate yield curves, option volatility and currency rates. Our warrant, which is accounted for as a derivative instrument, is valued using a Black-Scholes model. Key assumptions used in the valuation include risk-free interest rates; the service provider’s common stock price, equity volatility and common stock outstanding; exercise price; and details specific to the warrant. The value is also probability adjusted for management assumptions with respect to meeting the processing volume milestone targets. Refer to “Note 7 - Derivative Instruments” for further details on our derivative instruments. Other financial instruments, including accounts receivable and accounts payable, are carried at cost, which approximates their fair value because of the short-term nature of these instruments. The following table presents a reconciliation of the opening to closing balance of assets measured using significant unobservable inputs (Level 3) as of September 30, 2018 (in millions):

Recognition of warrant | 44 |
Change in fair value | 232 |
Closing balance as of September 30, 2018 | $ | 276 |
