 the fiscal year ended December 31, 2024. We have discussed the financial statements with management and Ernst & Young including discussions concerning the following:

| • | The reasonableness of significant accounting judgments and estimates, |

| • | The clarity and completeness of disclosures in the financial statements, |

| • | The quality, not just the acceptability, of the accounting principles, |

| • | The auditor’s report on the effectiveness of internal control over financial reporting, |

| • | The auditor’s report on the financial statements including Critical Audit Matters, |

| • | Matters required to be reported to the Audit Committee by the independent registered public accounting firm under the rules of the PCAOB including receipt of a letter confirming the independence of Ernst & Young, and |

| • | Management’s representations and certifications regarding the financial statements and internal control over financial reporting. |

Taking all these reviews and discussions into account, the Audit Committee members whose names are listed below, recommended to the Board that it approve the inclusion of the audited financial statements in our Annual Report on Form 10-K for the year ended December 31, 2024, for filing with the SEC.
