5. FAIR VALUE OF FINANCIAL INSTRUMENTS

 

    The Company’s financial instruments are measured at fair value consistent with authoritative guidance. This authoritative guidance defines fair value, establishes a framework for using fair value to measure assets and liabilities, and disclosures required related to fair value measurements.

 

    The guidance establishes a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:

 

Level 1 - instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.

 

Level 2 - instrument valuations are obtained from readily-available pricing sources for comparable instruments.

 

Level 3 - instrument valuations are obtained without observable market values and require a high level of judgment to determine the fair value.

 

    The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of February 28, 2021 (in thousands):

 

   Balance as of         
   February 28, 2021  Level 1  Level 2  Level 3
Money market funds  $80   $80   $—     $—   
Assets  $80   $80   $—     $—   

 

    The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of May 31, 2020 (in thousands):

 

   Balance as of May 31, 2020  Level 1  Level 2  Level 3
Money market funds  $80   $80   $—     $—   
Assets  $80   $80   $—     $—   

 

    Included in money market funds as of February 28, 2021 and May 31, 2020 is $80,000 restricted cash representing a security deposit for the Company’s United States manufacturing and office space lease which is included in other assets in the consolidated balance sheets.

 

    There were no financial liabilities measured at fair value as of February 28, 2021 and May 31, 2020.

 

    There were no transfers between Level 1 and Level 2 fair value measurements during the three and nine months ended February 28, 2021.

 

    The carrying amounts of financial instruments including cash, cash equivalents, receivables, accounts payable and certain other accrued liabilities, approximate fair value due to their short maturities.
