How to Record Die-Bank NRV Write-downs (Unpackaged Chip Obsolescence)

Accounting for a reduction in the value of unfinished dies sitting in storage when the market price for the final product falls below production cost.

💡 Accountant's Note

Dies can sit in a 'Die Bank' for months. Under ASC 330, if the 'Net Realizable Value' (expected selling price minus packaging/shipping costs) falls below the cost of the wafer and fabrication, the asset must be written down. In semiconductors, this is often triggered by the release of a 'New Revision' or a competitor's price cut in a specific segment (e.g., memory or mobile chips).

Practitioner & Systems Framework

💻 ERP Architecture

Requires an 'Inventory Aging' report tagged by 'Node' and 'Product Family.' If dies haven't been 'called' for packaging in over 180 days, a 50% or 100% reserve is usually applied automatically by the system.

⚠️ Audit Flags

Product Roadmap alignment. Auditors cross-reference the Die Bank inventory against the 'End-of-Life' (EOL) notices sent to customers. If a chip is EOL but still carries full value in the Die Bank, it is a material misstatement risk.

📄 Required Documentation

Inventory Aging report, latest Price List (Market Data), and the 'Technical Obsolescence' memo from the product manager.
