Fair Value Hierarchy
 
We apply the provisions of ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for our financial assets and liabilities that are re-measured and reported at fair value each reporting period and our nonfinancial assets and liabilities that are re-measured and reported at fair value on a non-recurring basis. We define fair value as the price 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.

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

Our financial assets that are re-measured at fair value on a recurring basis include money market funds that are classified as cash and cash equivalents in the condensed consolidated balance sheets. These money market funds are classified within Level 1 of the fair value hierarchy and are valued using quoted market prices for identical assets.

The fair value of the interest rate swaps, all of which qualify for cash flow hedge accounting, is recorded on our condensed consolidated balance sheet as an asset or liability with the related gains or losses reported as a component of accumulated other comprehensive income. The changes in fair value are reclassified from accumulated other comprehensive income into earnings in the same period that the hedged items affect earnings. The valuation technique used to determine fair value is the income approach. Under this approach, we use projected future interest rates, which fall into Level 2 of the fair value hierarchy as
defined by ASC 820, as provided by counterparties to the interest rate swap agreements and the fixed rates that we are obligated to pay under the agreements. See Note 8, “Derivatives” for additional information.

For the Hu-Friedy acquisition, additional purchase price payments were (i) contingent upon the achievement of certain commercial milestones through March 31, 2021, and (ii) contingent upon changes in our common stock price from the date of closing through a future date subject to a registration rights agreement. We estimated the aggregate fair value of these contingent consideration arrangements to be $38,371 at the date of acquisition, which was reported separately in our consolidated balance sheet. For the contingent consideration arrangements based upon the achievement of certain commercial milestones, the initial value assigned at the date of acquisition was determined on the basis of forecasted sales and gross profit percentage of Hu-Friedy products over the next twelve to eighteen months. During the second quarter of fiscal 2020, we paid $25,000 to settle a portion of this contingent consideration arrangement related to net sales achieved for the twelve month period ended December 31, 2019. For the remaining contingent consideration arrangement related to net sales and gross profit percentage, we reduced the fair value from a liability of approximately $17,210 to $0 due to the impact of the COVID-19 pandemic on Hu-Friedy’s current and expected performance.

For the contingent consideration arrangement based upon changes in our common stock price through a future date, we were required to pay to the sellers of Hu-Friedy an amount in cash equal to $35,000 minus the aggregate net proceeds received by the seller in connection with a future equity issuance if the amount of such aggregate net proceeds was less than $35,000. The initial fair value assigned to this contingent consideration arrangement was determined based on the closing price of our common stock at the date that the acquisition closed (October 1, 2019) relative to the contracted stock price stipulated in the purchase agreement. On February 13, 2020, we entered into a stock repurchase agreement with Dental Holding LLC, the former owners of Hu-Friedy (the “Repurchase Agreement”). The Repurchase Agreement amended the Hu-Friedy purchase and sale agreement and the related registration rights agreement to provide that we repurchase a portion of the shares from the seller included in the equity consideration transferred at a price per share of $64.51 (the “Repurchase”), which equals the closing price of shares of our common stock traded on the New York Stock Exchange on February 12, 2020. The Repurchase of 438,359 common shares was completed on February 13, 2020, and the shares were thereafter canceled and retired. The Hu-Friedy purchase and sale agreement further required us to pay to the seller an amount in cash equal to $35,000 minus the aggregate net proceeds received by the seller from an equity issuance if the amount of such aggregate net proceeds was less than $35,000 (the “True-Up Obligation”). The Repurchase Agreement further amended the purchase and sale agreement to provide that in satisfaction of the True-Up Obligation, we make a payment to the sellers in an amount equal to $6,721 to settle the contingent obligation, which amount equals $35,000 minus the aggregate amount of $28,279 paid to Dental Holding as consideration for the Repurchase. These payments were made to Dental Holding on February 13, 2020.

For the fiscal 2018 Aexis Medical BVBA acquisition, additional purchase price payments ranging from zero to $1,850 were contingent upon the achievement of certain purchase order targets through March 21, 2020. We estimated the original fair value of the contingent consideration using the weighted probabilities of the possible contingent payments. At the date of acquisition, we estimated the original fair value of the contingent consideration to be $1,292. In June 2020, we paid $1,691 to settle the contingent consideration.

We are required to reassess the fair value of contingent consideration payments on a periodic basis. Although we believe our assumptions are reasonable, different assumptions or changes in the future may result in different estimated amounts.

Disclosure of Fair Value of Financial Instruments
 
At October 31, 2020 and July 31, 2020, the carrying amounts for cash and cash equivalents (excluding money markets), accounts receivable and accounts payable approximated fair value due to the short maturity of these instruments.
We estimate the fair value of our convertible debt carried at face value less unamortized discount and issuance costs on a quarterly basis for disclosure purposes. The estimated fair value of our convertible debt is determined by Level 2 inputs and is based on observable market data including prices for similar instruments. At October 31, 2020 and July 31, 2020, the fair value of our convertible debt was $226,066 and $224,330, respectively.
