9. Fair Value of Financial Instruments

The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement. The Company uses the exit price method for estimating the fair value of loans for disclosure purposes.

The carrying amounts reported in the accompanying consolidated financial statements for cash, accounts receivable, accounts payable, and accrued expenses and other current liabilities (excluding the Milestone Rights liability) approximate their fair value due to their relatively short maturities. The fair value of the cash equivalents, MidCap Credit Facility, Mann Group promissory notes, 2024 convertible notes, and Milestone Rights liabilities are disclosed below.

Cash Equivalents and Restricted Cash — Cash equivalents consist of highly liquid investments with original or remaining maturities of 90 days or less at the time of purchase that are readily convertible into cash. As of December 31, 2020 and 2019, the Company held $67.0 million and $29.9 million, respectively, of cash and cash equivalents. The Company held $0.2 million and $0.3 million in restricted cash as of December 31, 2020 and 2019, respectively, which are comprised of money market funds. Restricted cash is used to collateralize a letter of credit. The fair value of these money market funds was determined by using quoted prices for identical investments in an active market (Level 1 in the fair value hierarchy).

Short-term investments— Short-term investments consist of highly liquid investments that are intended to facilitate liquidity and capital preservation. The fair value of short-term investments approximate their carrying value. The measurement of which is based on a market approach using quoted market values (Level 1 in the fair value hierarchy). As of December 31, 2020, the Company did not hold any short-term investments.

The fair value measurement of debt instruments is based on a discounted cash flow model and is sensitive to the change in yield (Level 3 in the fair value hierarchy):

				Hypothetical Change in Yield								Hypothetical Change in Notes Payable
	Yield			% Change			Hypothetical Yield			FV of Notes		FV		$ Change			% Change

Milestone Rights Liability — The fair value measurement of the Milestone Rights liability is sensitive to the discount rate and the timing of achievement of milestones. The Company utilized Monte-Carlo Simulation Method to simulate the Net Sales under a neutral framework to estimate the payment. The Company then discounted the future expected payments at cost of debt with a term equal to the simulated time to payout based on cumulative sales.
