Note 5 - Fair Value Measurements


The Company uses the fair value hierarchy to measure the value of its financial instruments. The fair value hierarchy is 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 its own market assumptions. The basis for fair value measurements for each level within the hierarchy is described below:


Level 1 – Quoted prices for identical assets or liabilities in active markets.
Level 2 – Quoted prices for identical or similar assets and liabilities in markets that are not active; or other model-derived valuations whose inputs are directly or indirectly observable or whose significant value drivers are observable.
Level 3 – Valuations derived from valuation techniques in which one or more significant inputs to the valuation model are unobservable and for which assumptions are used based on management estimates.


The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value.


The carrying amounts of cash equivalents, current portion of restricted cash, prepaid expenses and other current assets, accounts payable, current portion of lease liabilities and accrued expenses approximate fair value due to the short-term nature of these instruments.


A summary of the assets and liabilities carried at fair value in accordance with the hierarchy defined above is as follows:


          Fair Value Hierarchy  
December 31, 2022   Total     (Level 1)     (Level 2)     (Level 3)  
Marketable Debt Securities:                                
U.S. Treasury Bonds   $ 959     $ 959     $     $  
U.S. Government Notes     15,603             15,603        
Corporate Debt Securities     5,371             5,371        
Total   $ 21,933     $ 959     $ 20,974     $  



          Fair Value Hierarchy  
December 31, 2021   Total     (Level 1)     (Level 2)     (Level 3)  
Marketable Debt Securities:                                
U.S. Government Notes   $ 19,277     $     $ 19,277     $  
Corporate Debt Securities     9,065             9,065        
State and Municipal Bonds     250             250        
Total   $ 28,592     $     $ 28,592     $  


U.S. treasury bonds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices for identical assets in active markets. Marketable debt securities consisting of U.S. government notes, corporate debt securities and state and municipal bonds are classified as Level 2 and are valued using quoted market prices in markets that are not active.
