Meaning
An accounting methodology determines which party is responsible for the cost of units that fail during the manufacturing process. The yield loss allocation defines the acceptable percentage of scrap and the threshold at which the supplier must pay for the wasted materials. it is a critical part of a manufacturing services agreement.
Financial Responsibility
Factories are expected to maintain a certain level of efficiency, but some failures are inevitable in complex electronics. The yield loss allocation ensures that the buyer is not penalized for poor manufacturing performance while protecting the supplier from the cost of inherent design flaws. This balance is negotiated based on the maturity of the production process.
Production Risk
Early runs of a new product often have higher failure rates as the line is being optimized. A yield loss allocation for these initial batches is usually higher than for mature products that have been in production for several months.
Scrap Settlement
Manufacturers must provide regular reports on the number of failed units and the reasons for the failures. The yield loss allocation determines the final credit or debit applied to the monthly invoice based on these results. It encourages the factory to improve its processes to stay within the agreed limits.
Clear rules for scrap handling reduce friction during the reconciliation of production accounts.
