11. Fair Value Measurement

The following table presents information about the Company's financial assets and liabilities that are measured at fair value on a recurring basis and indicates the fair value hierarchy of the valuation:

    Fair Value Measurements as of
June 30, 2022
Using:
 
    Level 3     Total  
Assets: $     $ -  
Liabilities:            
Convertible promissory notes   5,185,711     5,185,711  
  $ 5,185,711   $ 5,185,711  

During each of the six-month periods ended June 30, 2022 and 2021, there were no transfers between Level 1, Level 2, or Level 3. There were no other financial assets or liabilities measured at fair value on a recurring basis as of June 30, 2022.

The following table summarizes the change in Level 3 financial instruments during the six-month period ended June 30, 2022.

Fair value at December 31, 2021 $ 3,798,516  
Fair value of new at issuances   2,159,526  
Repayments   (85,880 )
Mark to market adjustment   5,124,945  
Settlement   (5,811,396 )
Fair value at June 30, 2022 $ 5,185,711  

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. The fair value of the convertible promissory notes at issuance and subsequent financial reporting dates was estimated based on significant inputs not observable in the market, which represent level 3 measurements within the fair value hierarchy.

The fair value of the convertible promissory notes at issuance and at each reporting period was estimated based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The Company used a scenario-based binomial model to estimate the fair value of the convertible promissory notes. The model determines the fair value from a market participant's perspective by evaluating the payouts under hold, convert, or call decisions. The most significant estimates and assumptions used as inputs are those concerning type, timing and probability of specific scenario outcomes. Specifically, the Company assigned a probability of default ("PD"), which would increase the required payout as described in note 10 and calculated the fair value under each scenario. The PD was assumed to be 50% as at December 31, 2021 and during the three months ended March 31, 2022. The PD as at and during the three months ended June 30, 2022 was assumed to be 75%. Increasing (decreasing) the probability of default would result in a significantly higher (lower) fair value measurement.

Other significant unobservable inputs include the expected volatility, discount for lack of marketability and the credit spread. The expected volatility was based on the historical volatility over a look-back period that was consistent with the balance-remaining term of the instruments. A range of 70% to 90% was used for the expected volatility. The discount for lack of marketability was determined using a range of option pricing methodologies using the remaining restriction term corresponding to each instrument on the relevant valuation date. A range of 30% to 40% was used for the discount for lack of marketability. The credit spread was determined in reference to credit yields of companies with similar credit risk at the date of valuation. A premium of 10% was added to the credit spread as an instrument specific adjustment to reflect the Company's risk of default. A range of 15.4% to 19.3% was used for the credit spread.
