Fair Value of Financial Instruments | 15. Fair Value of Financial Instruments Certain financial instruments that are not carried at fair value on the consolidated statements of financial condition are carried at amounts that approximate fair value. These instruments include deposits with clearing organizations and accounts receivable. Following is a description of the fair value methodologies used for the Company's instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy: The Company's money market funds are classified within level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets. Contingent consideration is classified within level 3 of the fair value hierarchy because the valuation requires assumptions that are both significant and unobservable. The contingent consideration valuation is determined using a monte carlo simulation, with key inputs being the standard deviation applied to the Company's new credit platforms' revenues, revenue multiple and discount rate. At December 31, 2017, the inputs in the valuation are as follows:
Standard deviation |  | $ | 1,666,667 |
Revenue multiple |  |  | 7.03x |
Discount rate |  |  | 1.64 | %
The Company has no instruments that are classified within level 2 of the fair value hierarchy. The fair value measurements are as follows (in thousands):
|  | Quoted Prices in |  |  |  |  |  |  |  |  |
|  | active Markets |  | Significant |  | Significant |  |  |
|  | for Indentical |  | Observable |  | Unobservable |  |  |
