Biological Growth (Physical Change)
Adjusting the value of animals as they get older, heavier, and more valuable.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Biological Assets (Livestock) | Asset (+) | 1,500.00 | - |
| Change in Fair Value (Physical) | Revenue (+) | - | 1,500.00 |
💡 Accountant's Note
IAS 41 requires you to separate growth into 'Price Change' and 'Physical Change.' This entry records the value added because the animals grew larger.
Practitioner & Systems Framework
💻 ERP Architecture
The physical change component is calculated by holding market prices constant at the prior-period level and revaluing the herd at current physical attributes (weight, age, grade). The difference from the prior carrying amount — using the same prices — is the physical change. This requires the ERP or the farm management system to track weight gain data (periodic weigh events) or age-based grade progression schedules. The price change component is then the residual: total fair value movement minus the physical change. Some agricultural ERPs compute this split automatically if configured with a price × quantity model.
⚠️ Audit Flags
(1) Is the split between price and physical change mathematically consistent? The sum of the two components must equal the total change in fair value for the period. (2) Weigh data accuracy — is there physical weigh evidence (sale yard dockets, on-farm scale records) to support the claimed weight gain? Estimated growth rates without physical verification are a higher-risk measurement. (3) Consistent methodology — the method for isolating physical vs. price change must be applied consistently year-over-year; a change in method requires disclosure as an accounting estimate change.
📄 Required Documentation
Period-start and period-end herd census with physical attributes (weight, age, grade), weigh records or age-grade transition schedules, market price data at both dates, and the physical/price change reconciliation calculation.
