Work-in-progress (WIP) refers to partially completed goods in a manufacturing process.
Accounting principle for valuation of WIP: Conservative / Lower of Cost or Market (Net Realizable Value).
Cost price: Expenses incurred so far in producing the goods.
Market price / Net realizable value: Estimated selling price minus completion and selling costs.
This ensures that assets are not overstated in the financial statements.
Other options:
Market price: Could overstate WIP.
Cost price: Ignores possible fall in realizable value.
Selling price: Not used for valuation in accounts.
