Fair Value Measurements

9 Months Ended

Dec. 31, 2021

Fair Value MeasurementsThe preparation of the Company’s unaudited condensed consolidated financial statements in accordance with U.S. GAAP requires certain assets and liabilities to be reflected at their fair value. Fair value is defined as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be

classified and disclosed into one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

•Level 1—Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

•Level 2—Valuations are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly.

•Level 3—Valuations are based on inputs that are unobservable (supported by little or no market activity) and significant to the overall fair value measurement.

For a description of the methods and assumptions that are used to estimate the fair value and determine the fair value hierarchy classification of each class of the Company’s financial instruments, see Note 2, “Summary of Significant Accounting Policies,” and Note 3, “Fair Value Measurements,” to the Company’s audited consolidated financial statements included in its Annual Report on Form 10-K for the fiscal year ended March 31, 2021, filed with the SEC on May 11, 2021.

Financial Instruments Not Measured at Fair Value on a Recurring Basis

The Company recorded the cost share advance from Pfizer, which is included in Level 2 of the fair value hierarchy, at its estimated fair value as of the transaction date. As discussed in Note 8(B), on the transaction date, the cost share advance from Pfizer was discounted to fair value using the Company’s estimated incremental borrowing rate over the period in which the cost share advance is expected to be utilized. The recorded amount has been and will continue to be reduced each reporting period by the amount of Allowable Expenses applied to the cost share advance. There were no non-recurring fair value assets as of December 31, 2021 and March 31, 2021.
