MB-310 Manage Fixed Assets Practice Question
A multinational company in Dynamics 365 Finance has a fixed asset book configured with a reducing balance depreciation method and a Half year (start of year) convention. An accountant notices that for an asset placed in service on October 15, the first depreciation journal posted a full half-year of depreciation in the current fiscal year, and the remaining half will be applied in the final year of the asset's life. The controller wants to understand why this happened and whether it is correct. What should the functional consultant explain?
⚠ Common exam trap
The trap here is believing that reducing balance methods bypass depreciation conventions, when conventions apply across methods to control first- and last-year proration.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Half year (start of year) convention assumes the asset was placed in service at the start of the fiscal year, so a full half-year of depreciation is taken in the acquisition year and the remaining half in the disposal year.
The Half year (start of year) convention assumes the asset entered service at the beginning of the fiscal year of acquisition, producing a half-year of depreciation in that year and the remaining half in the final year. This behavior is expected and is independent of the reducing balance method, which only governs how the rate is applied to net book value.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Half year (start of year) convention applies a full year of depreciation in the acquisition year and a half year in the following year.
Why it's wrong here
That description matches the Half year (next year) convention behavior in some contexts, not Half year (start of year). The Half year (start of year) convention produces a half-year of depreciation in the acquisition year itself, not a full year, because the asset is treated as if placed in service at the fiscal year start.
- ✗
The system miscalculated because reducing balance methods ignore conventions and should always prorate depreciation by the number of days in service.
Why it's wrong here
Reducing balance methods do respect depreciation conventions. The convention controls the timing and proration of depreciation in the first and last years, while the method controls the rate applied to the net book value. The system did not miscalculate; it applied the configured convention consistently with the book setup.
- ✗
The depreciation profile is misconfigured; the Half year convention should only be used with the straight line method and not with reducing balance.
Why it's wrong here
Depreciation conventions in Dynamics 365 Finance are independent of the depreciation method. You can combine Half year, Full month, Mid quarter, or other conventions with Straight line, Reducing balance, Manual, or Consumption methods. The combination used here is valid and produced the expected result for the chosen convention.
- ✓
The Half year (start of year) convention assumes the asset was placed in service at the start of the fiscal year, so a full half-year of depreciation is taken in the acquisition year and the remaining half in the disposal year.
Why this is correct
The Half year (start of year) convention in Dynamics 365 Finance treats the asset as if it entered service at the beginning of the fiscal year in which it was acquired. That results in a half-year of depreciation in the acquisition year regardless of the actual in-service date, with the remaining half applied in the final year. This is standard behavior for that convention.
