Depreciation - Principles of Accounting (9593) - GCE A-Level - Higher 2 (H2)

Welcome to the World of Non-Current Assets!

Hello there! Today, we are diving into one of the most important chapters in your H2 Principles of Accounting journey: Depreciation. This topic sits under the section "Representation and Presentation of Investing Activities."

Think about a smartphone you bought three years ago. Is it worth the same today? Probably not! It’s likely slower, the battery doesn’t last as long, and newer models have been released. In accounting, we don't just "guess" how much value is lost; we use Depreciation to systematically spread the cost of an asset over the years we use it. Let's break it down!

1. What Exactly is Depreciation?

Depreciation is the systematic allocation of the cost of a non-current asset (like machinery, vehicles, or equipment) over its useful life.

It is important to remember that depreciation is not an attempt to find the "market value" of an asset. Instead, it is an application of the Matching Principle. We want to match the expense of using the asset against the income it helps us generate each year.

Why do assets depreciate?

Wear and Tear: Physical use of the asset (e.g., a delivery van driving thousands of kilometers).
Obsolescence: Newer, better technology makes the old asset less efficient (e.g., an old computer).
Passage of Time: Some assets have a legal life limit (e.g., a 30-year lease on a building).

Quick Review:
Depreciable Amount = Cost $-$ Scrap Value (also called Residual Value).
This is the total amount of value we expect the asset to lose over its entire life.

Key Takeaway: Depreciation is an expense (Income Statement) and it increases Accumulated Depreciation (a contra-asset in the Balance Sheet).

2. Prerequisite Check: Capital vs. Revenue Expenditure

Don't worry if you've forgotten this! Before we can depreciate an asset, we need to know its Cost. Only Capital Expenditure is added to the cost of the asset.

Capital Expenditure: Costs to acquire the asset or get it ready for use (e.g., purchase price, delivery charges, installation costs). These are "capitalised" and then depreciated.
Revenue Expenditure: Day-to-day costs to maintain the asset (e.g., repair costs, insurance, petrol). These are recorded as immediate expenses and are not depreciated.

Did you know? Land is generally not depreciated because it has an unlimited useful life. It doesn't wear out or get "used up" like a machine does!

3. Two Main Methods of Depreciation

The syllabus requires you to master two specific ways to calculate the annual depreciation charge. The method chosen should reflect the pattern in which the asset’s economic benefits are consumed.

Method A: The Straight-line Method

This method assumes the asset provides the same amount of benefit every year. The depreciation expense is a fixed, equal amount each year.

Formula 1 (using years):
$ \text{Annual Depreciation} = \frac{\text{Cost} - \text{Scrap Value}}{\text{Estimated Useful Life}} $

Formula 2 (using a percentage rate):
$ \text{Annual Depreciation} = (\text{Cost} - \text{Scrap Value}) \times \text{Rate} \% $

Method B: The Reducing-balance Method

This method assumes the asset is more efficient and productive in its early years. Therefore, the depreciation charge is higher in the beginning and decreases over time. This is common for high-tech items or vehicles.

Formula:
$ \text{Annual Depreciation} = \text{Net Book Value (NBV)} \times \text{Rate} \% $

Wait, what is NBV?
Net Book Value (NBV) = Cost $-$ Accumulated Depreciation to date.

Common Mistake: Students often forget to subtract Accumulated Depreciation when using the Reducing-balance method, but they mistakenly try to subtract Scrap Value. Remember: In Reducing-balance, we ignore Scrap Value in the yearly calculation (the NBV naturally "reduces" toward the scrap value over time)!

Key Takeaway: Straight-line = Same amount every year. Reducing-balance = Percentage of the "leftover" value (NBV).

4. Dealing with Partial Years

Businesses don't always buy assets on the first day of the financial year! You need to check the company's policy:

Full-year policy: A full year's depreciation is charged in the year of purchase, regardless of the date. No depreciation is charged in the year of disposal.
Pro-rata (Monthly) policy: Depreciation is calculated based on the number of months the asset was actually owned during that year.

Example of Pro-rata: If a machine was bought on 1 October and the financial year ends on 31 December, you only charge $ \frac{3}{12} $ of the annual depreciation for that first year.

5. Recording Depreciation (Journal Entries)

How do we put this into the books? We use a "Double-Entry" system. We want to show the expense, but we also want to keep the Original Cost of the asset visible on the books.

The Journal Entry:
Debit: Depreciation Expense (to increase expenses)
Credit: Accumulated Depreciation — [Asset Name] (to increase the contra-asset)

Why use an "Accumulated" account?
Imagine you have a $ \$10,000 $ car. If you credited the "Car" account directly every year, you'd eventually forget what the car originally cost! By using Accumulated Depreciation, the Balance Sheet can show: "The car cost $ \$10,000 $, and so far, we have used up $ \$4,000 $ of it."

6. Sale of Property, Plant, and Equipment (Disposal)

When we sell an asset, we need to find out if we made a Gain or a Loss. This is the difference between what we sold it for and what it was worth on our books at that moment.

Step-by-step calculation:
1. Calculate the NBV at the date of sale: $ \text{Cost} - \text{Accumulated Depreciation} $.
2. Compare NBV to the Sale Proceeds (Cash or Trade-in value).
3. $ \text{Gain/Loss on Disposal} = \text{Sale Proceeds} - \text{NBV} $.

If Proceeds > NBV: You have a Gain on sale (Other Income).
If Proceeds < NBV: You have a Loss on sale (Other Expense).

Key Takeaway: Gain/Loss isn't about the original cost; it’s about comparing the cash received to the remaining book value.

7. Presentation in Financial Statements

In the GCE A-Level H2 Syllabus, you must be able to present extracts of the financial statements. This is how the information looks to stakeholders.

Income Statement Extract (for the year ended...)

Other Income
Gain on sale of [Asset] ... $ \$ $xxxx

Expenses
Depreciation of [Asset] ... $ \$ $xxxx
Loss on sale of [Asset] ... $ \$ $xxxx

Balance Sheet (Statement of Financial Position) Extract

Non-current Assets
(Columns: Cost | Accumulated Depreciation | Net Book Value)
[Asset Name] ... $ \$ $xxxx | ($ \$ $xxxx) | $ \$ $xxxx

Encouragement: Depreciation can feel like a lot of math at first, but it follows a very logical pattern. Once you master the difference between the Straight-line and Reducing-balance formulas, the rest is just keeping your numbers organized!

Summary: The Depreciation Cheat Sheet

Depreciation: Spreading the cost of a long-term asset over its useful life.
NBV: The "book value" ($ \text{Cost} - \text{Accumulated Depreciation} $).
Straight-line: Calculation is based on Cost.
Reducing-balance: Calculation is based on NBV.
Disposal: Selling the asset. Compare the cash you get to the NBV to find the Gain or Loss.
Prudence Principle: We depreciate to avoid overstating the value of our assets and profit.
