However, our audit doesn't relieve you or management of your responsibilities. Perform an audit in accordance with: • Generally accepted auditing standards issued by the AICPA • Government Auditing Standards issued by the Comptroller General of the United States Design the audit to provide reasonable assurance about whether the financial statements are free of material misstatement. Consider internal controls over financial reporting and compliance as a basis for designing effective audit procedures.

When applicable, communicate particular matters required by law or regulation, by agreement with you, or by other requirements applicable to the engagement. 5 Significant Risks Identified During the planning of the audit, we have identified the following significant audit risks: INTERNAL CONTROL OVER FINANCIAL REPORTING AND SIGNIFICANT BUSINESS CYCLES CASH RECEIPTS, CASH, DISBURSEMENTS, PAYROLL, PROJECT MONITORING & CONSTRUCTION IN PROGRESS COST ADDITIONS EXISTENCE AND VALUATION OF CAPITAL ASSETS REVENUE RECOGNITION CLASSIFICATION OF CONSTRUCTION IN PROGRESS BALANCES EVALUATION OF LEASE REVENUE AND RELATED RECEIVABLE BALANCES MANAGEMENT ESTIMATES ENVIRONMENTAL LIABILITY AND LEGAL RESERVES, PENSION ASSUMPTIONS COMPLIANCE WITH FEDERAL LAWS AND REGULATIONS, UNIFORM GRANT GUIDANCE (SINGLE AUDIT) FINANCIAL STYSTEMS IT CONTROL TESTING 6 Audit Timeline 2025 2026 SEPTEMBER/OCTOBER DECEMBER MARCH/APRIL BY APRIL 30 MAY Planning meetings with management Entrance meeting with Audit Committee Perform final audit fieldwork for the financial statements, Single Audit, and PFC Final QC reviews, and finalize auditors' reports Presentation of the audit results to Audit Committee Presentation of audit results to management Perform AUP procedures as required by the EPA and Department of Ecology Audit planning and risk assessment Interim testing of internal controls Assessment of IT environment and testing of system internal controls 7 Recent Accounting Developments RECENT AND UPCOM ING ACCOUNTING DEVELOPMENTS GASB Standards • GASB Statement No. 102, Certain Risk Disclosures (effective 2025) • GASB Statement No. 103, Financial Reporting Model Improvements (effective 2026) • GASB Statement No. 104, Disclosures of Certain Capital Assets (effective 2026) 9 THANK YOU
