Such management estimates and assumptions include, but are not limited to, the stand-alone selling price (SSP) for each distinct performance obligation included in customer contracts with multiple performance obligations, the period of benefit for deferred commissions, purchase price allocation for business combinations, stock-based compensation expenses, the assessment of the useful life and recoverability of our property and equipment, goodwill and identifiable intangible assets, fair value of convertible notes, income taxes and legal contingencies.

We hold cash at financial institutions that management believes are high credit, quality financial institutions and invest in securities with a minimum rating of BBB by Standard & Poor’s, Baa2 by Moody’s, or BBB by Fitch to minimize our credit risks. Our derivative contracts expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the arrangement. We mitigate this credit risk by transacting with major financial institutions with high credit ratings and entering into master netting arrangements, which permit net settlement of transactions with the same counterparty. While the contract or notional amount is often used to express the volume of foreign currency derivative contracts, the amounts potentially subject to credit risk are generally limited to the amounts, if any, by which the counterparties’ obligations under the agreements exceed the obligations of the Company to the counterparties. We are not required to pledge, and are not entitled to receive, cash collateral related to these derivative instruments. We are also exposed to credit risk under the convertible note hedge transactions that may result from counterparties’ non-performance. </span></div><div style="line-height:120%;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Credit risk arising from accounts receivable is mitigated due to our large number of customers and their dispersion across various industries and geographies.
