Fair Value Disclosures [Abstract]  
Fair value Fair value
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value measurements are based on a fair value hierarchy, based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value as follows:

Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted market prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The carrying amount of cash and cash equivalents, restricted cash, accounts receivable, inventory, and accounts payable and accrued expenses, as reflected on the condensed consolidated balance sheets, approximate fair value because of the short-term maturity of these instruments. These estimated fair values may not be representative of actual values of the financial instruments that could have been realized or that will be realized in the future.

The warrant liabilities (see Note 13—Warrant liabilities) and promotional agreements (see Note 17—Commitments and contingencies) are Level 3 instruments and use internal models to estimate fair value using certain significant unobservable inputs which requires determination of relevant inputs and assumptions. Accordingly, changes in these unobservable inputs may have a significant impact on fair value. Such inputs include risk free interest rate, expected dividend yield, expected volatility, and expected vesting date. These Level 3 liabilities generally decrease (increase) in value based upon an increase (decrease) in risk free interest rate, expected vesting date, and expected dividend yield. Conversely, the fair value of these Level 3 liabilities generally increase (decrease) in value if the expected volatility were to increase (decrease).
