. These inputs reflect management’s own assumption about the assumptions a market participant would use in pricing the working capital loan.

The convertible promissory note was classified within Level 3 of the fair value hierarchy due to the use of unobservable inputs. Inherent in pricing models are assumptions related to expected share-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the note. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the note. The expected life of the note is assumed to be equivalent to their remaining contractual term.

NORTHVIEW ACQUISITION CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS Note 8 — Fair Value Measurements (cont.) The Company utilizes a Monte Carlo model to estimate the fair value of the conversion feature within the securities purchase agreement, which is required to be recorded at its initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the conversion feature are recognized as non -cashgains or losses in the accompanying condensed consolidated statements of operations. The key assumptions in the model relate to expected share -pricevolatility, risk -freeinterest rate, exercise price, expected term and the probability of occurrence of the transaction. The expected volatility was based on the average volatility of special purpose acquisition companies that are searching for an acquisition target. The risk -freeinterest rate is based on the U.S. Treasury zero -couponyield curve on the grant date for a maturity similar to the expected remaining life of the note. The expected life of the note is assumed to be equivalent to their remaining contractual term.
