Note 10 — Fair Value Measurement
 
Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. At December 31, 2017 and 2016, the warrant balance of approximately $0 and $0.3 million, respectively, were classified as Level 3 instruments.
 
The following table sets forth the changes in the estimated fair value for the Company’s Level 3 classified derivative warrant liability (in thousands):

On June 26, 2017, pursuant to the terms of the Company’s $3.0 million NSC Note, upon the closing of the Company’s IPO, the Company issued to National warrants for 125,000 common shares at par with a fair value of $0.8 million, relating to its aggregate gross proceeds from its third-party offerings exceeding five times the value of the debt. Upon the issuance of the warrant, Fortress was removed as the guarantor on the note (see Note 7).
 
Additionally, on June 26, 2017, the Company issued 2,488 warrants to purchase common shares of the Company at $4.02, to Westpark, in connection with their role as placement agent.
 
The fair value of the NSC Contingently Issuable Warrants was determined at December 31, 2016 for approximately $0.3 million by applying management’s estimate of the probability of issuance of the Contingently Issuable Warrants together with the Black-Scholes option pricing model with the following key assumptions:
