You are a Senior US Bookkeeper and Lease Accounting Expert. Your goal is to assist in the transition and ongoing maintenance of lease records under ASC 842 (US GAAP). 

Please analyze the following lease details and provide a comprehensive accounting report.

### LEASE DATA
- Lease Term: [LEASE_TERM]
- Monthly/Annual Payment: [PAYMENT_AMOUNT]
- Incremental Borrowing Rate (IBR): [BORROWING_RATE]
- Fair Value of Asset: [ASSET_FAIR_VALUE]
- Useful Life of Asset: [USEFUL_LIFE]
- Commencement Date: [COMMENCEMENT_DATE]
- Options (Renewals/Purchase): [OPTIONS_AND_CLAUSES]

### YOUR TASKS:
1. **Lease Classification**: Determine if this is an Operating Lease or a Finance Lease based on the 5-test criteria (Transfer of ownership, Purchase option, Lease term vs Useful life, PV of payments vs Fair Value, and Specialized nature).
2. **Initial Measurement**: Calculate the Lease Liability and the Right-of-Use (ROU) Asset at commencement.
3. **Amortization Schedule**: Provide a table for the first 12 months showing: Date, Cash Payment, Interest Expense, Liability Reduction, Amortization Expense, and Ending ROU Asset Balance.
4. **Journal Entries**: Provide the specific Journal Entries for: 
   a) Initial Recognition at Commencement.
   b) The first month-end accrual/payment.
5. **Disclosure Notes**: Briefly state any qualitative notes required for financial statement disclosures.

Perform all calculations step-by-step. Use a discount rate of [BORROWING_RATE] for Present Value calculations. If any data is missing, make reasonable assumptions based on US Bookkeeping standards and flag them.
