Vulnerabilities in our systems pose material risks to our business. We have not and may not in the future, however, detect and remediate all such vulnerabilities including on a timely basis. Further, we have and may in the future experience delays in developing and deploying remedial measures and patches designed to address identified vulnerabilities.

The capped call transactions are expected generally to reduce the potential dilution to our common stock upon any conversion of our convertible notes and/or offset any cash payments we are required to make in excess of the principal amount of converted notes (if and when we elect to settle the conversion spread value in cash), as the case may be, with such reduction and/or offset subject to a cap.

Removed
Certain organizations that provide corporate governance and other corporate risk information to investors and shareholders have developed, and others may in the future develop, scores and ratings to evaluate companies and investment funds based upon ESG or “sustainability” metrics.
Added
Our information security management program generally follows processes outlined in frameworks such as the National Institute of Standards and Technology Cyber Security Framework and ISO 27001 international standard for Information Security. Due to the nature and location of the work that we perform, we are often required to obtain certifications required by our clients and regulators.
Removed
Many investment funds focus on positive ESG business practices and sustainability scores when making investments and may consider a company’s ESG or sustainability scores as a reputational or other factor in making an investment decision.
Added
We evaluate and evolve our security measures as appropriate. We consult with external parties, such as cybersecurity firms and risk management and governance experts, on risk management and strategy.
Removed
In addition, investors, particularly institutional investors, use these scores to benchmark companies against their peers and if a company is perceived as lagging, these investors may engage with such company to improve ESG disclosure or performance and may also make voting decisions, or take other actions, to hold these companies and their boards of directors accountable.
Added
Identifying, assessing, and managing cybersecurity risk is integrated into our overall risk management program which includes cybersecurity and data privacy training and policies and procedures designed to (a) respond to new requirements in global privacy and cybersecurity laws and (b) prevent, detect, respond to, mitigate and recover from identified and significant cybersecurity threats.
Removed
We may also face reputational damage in the event our corporate 30 responsibility initiatives or objectives do not meet the standards set by our investors, stockholders, lawmakers, listing exchanges or other constituencies, or if we are unable to achieve an acceptable ESG or sustainability rating from third party rating services.
Added
We also have a vendor risk assessment process consisting of, depending on the nature and sensitivity of the supplier and data they process on our behalf, the distribution and review of supplier questionnaires designed to help us evaluate cybersecurity risks that we may encounter when working with third parties that have access to confidential and other sensitive company information.
Removed
A low ESG or sustainability rating by a third-party rating service could also result in the exclusion of our common stock from consideration by certain investors who may elect to invest with our competition instead. Ongoing focus on corporate responsibility matters by investors and other parties as described above may impose additional costs or expose us to new risks.
Added
We routinely assess our high-risk suppliers’ conformance to industry cybersecurity standards and evaluate them for additional information as circumstances change. Refer to Item 1A.
