Note 3. Fair Value Measurements

 

Our financial instruments consist primarily of cash and cash equivalents, trade accounts receivable, obligations under trade accounts payable, and debt. Due to their short-term nature, the carrying values for cash and cash equivalents, trade accounts receivable, and trade accounts payable approximate fair value. Cash equivalents on our Consolidated Balance Sheets consisted of $0 held in a money market account as of March 31, 2022, compared to $230,822 held in a money market account as of  March 31, 2021. We used the money market funds for the Agena Acquisition, see Note 4. "Significant Transactions." We measure our cash equivalents at fair value using quoted market prices in an active market, and we classify them within Level 1 of the fair value hierarchy.

 

Historically, the financial instruments that subject us to the highest concentration of credit risk are cash and cash equivalents and accounts receivable. It is our policy to invest in highly liquid cash equivalent financial instruments with high credit ratings and to maintain low single issuer exposure (except U.S. treasuries). Concentration of credit risk with respect to accounts receivable is limited to customers to which we make significant sales. To manage credit risk, we consider the creditworthiness of new and existing customers, and we regularly review outstanding balances and payment histories. We may require pre-payments from customers under certain circumstances and may limit future purchases until payments are made on past due amounts. We reserve an allowance for potential write-offs of accounts receivable, but we have not written off any significant accounts to date.

 

We have outstanding $172,500 aggregate principal of 1.375% convertible senior notes due August 15, 2025. We estimate the fair value of the Notes based on the last actively traded price or observable market input preceding the end of the reporting period. The estimated fair value and carrying value of the Notes were as follows:

 

  

March 31, 2022

  

March 31, 2021

 $169,365  $185,438  $145,675  $188,780 

 

The carrying value of the Notes increased as a result of the adoption of ASU 2020-06, discussed further in Note 1. "Description of Business and Summary of Significant Accounting Policies" and Note 8. "Indebtedness." 

 

Assets recognized or disclosed at fair value in the Consolidated Financial Statements on a nonrecurring basis include items such as property and equipment, operating lease assets, goodwill, and other intangible assets, including those that were part of the Agena Acquisition. These assets are measured at fair value if determined to be impaired. Preliminary fair values assigned to assets acquired and liabilities assumed in the Agena Acquisition, except deferred revenues, were measured using Level 3 inputs, as discussed further in Note 4. "Significant Transactions." There were no transfers between the levels of the fair value hierarchy during the fiscal years ended March 31, 2022 and  March 31, 2021.
