The fair value of the money market funds, commercial paper, and treasury bills is based on quoted market prices in an active market. Closing prices are readily available from active markets and are used as being representative of fair value. The Company classifies these securities as level 1. The only equity security owned by the Company is an investment in a limited-marketable company. There is an insignificant market for this limited-marketable company and the Company has determined the value based on financial and other factors, which are considered level 3 inputs in the fair value hierarchy. Management estimated the probability of meeting the revenue targets over the measurement period to determine the fair value of the contingent earn-out, which is considered a level 3 input in the fair value hierarchy. The change in level 3 assets at fair value on a recurring basis is summarized as follows:
|  | Years Ended December 31, |
|  | 2018 |  |  | 2017 |
Beginning Balance |  | $ | 45 |  |  | $ | 0 |
Increase in value |  |  | 0 |  |  |  | 45 |
Ending Balance |  | $ | 45 |  |  | $ | 45 |
The 2017 increase in value is due to additional information obtained on equity securities held in a company with a limited market for its securities. The change in level 3 liabilities at fair value on a recurring basis is summarized as follows:
|  | Years Ended December 31, |
|  | 2018 |  |  | 2017 |
Beginning Balance |  | $ | 150 |  |  | $ | 195 |
Credit to Earnings |  |  | 0 |  |  |  | (45 | )
Payments |  |  | (150 | ) |  |  | 0 |
Ending Balance |  | $ | 0 |  |  | $ | 150 |
The 2017 decrease in the contingent earn-out, which is recorded in general and administrative expenses, reflects the Company’s expectation of lower future contingent payments related to a general manufacturing sector slowdown as well as slower adoption of the Company’s wireless product offerings. The 2018 decrease reflects the final payment of the liability according to the terms of the underlying agreement. No liability exists at December 31, 2018.
