The fair value of the private placement warrants, Series A warrants and share subscription liability are based on significant unobservable inputs, which represent Level 3 measurements within the fair value hierarchy. In determining the fair value of the warrant and share subscription liability, the Company used the Black-Scholes and Monte Carlo option-pricing model as applicable to estimate the fair value using unobservable inputs including the expected term, expected volatility, risk-free interest rate, and dividend yield. The following table presents a summary of the changes in the fair value of the Series A and private placement warrants (in thousands):
