Santos  (OTCPK:STOSF) Depreciation, Depletion and Amortization Explanation

One of the key tenets of Generally Accepted Accounting Principles (GAAP) is the matching principle. The matching principle states that companies should report associated costs and benefits at the same time.

For example:

If a company buys a $300 million cruise ship in 1982 and then sells tickets to passengers for the next 30 years, the company should not report a $300 million expense in 1982 and then ticket sales for 1982 through 2012. Instead, the company should spread the purchase price of the ship (the cost) over the same time period it sells tickets (the benefit).

To create income statements that meet the matching principle, accountants use an expense called depreciation.

So, instead of reporting a $300 million purchase expense in 1982, the company might:

Report a $30 million depreciation expense in 1982, 1983, 1984...and every year after that for the 30 years the company expects to sell tickets to passengers on this cruise ship.

To calculate depreciation, a company must make estimates and choices such as:

The cost of the asset
The useful life of the asset
The salvage value of the asset at the end of its useful life
And a way of spreading the cost of the asset to match the time when the asset provides benefits

The range of different ways of spreading the cost under GAAP accounting is too long to list. However, public companies in the United States explain their depreciation choices to shareholders in a note to their financial statements. It is critical that investors read this note. Investors can find this note in the company's 10-K.

Past depreciation expenses accumulate on the balance sheet. Most public companies choose not to show this contra asset account on the balance sheet they present to shareholders. Instead, they simply show a single item. This single asset item may be marked Net. Such as Property, Plant, and Equipment - Net. It is actually the asset account netted against the contra asset account.

A contra asset account is an account that offsets an asset account. So, for example a company might have:

Property, Plant, and Equipment - Gross: $150 million
Accumulated Depreciation: $120 million
Property, Plant, and Equipment - Net: $30 million

In this case, the only item likely to be shown on the balance sheet is Property, Plant, and Equipment - Net. This is the cost of the company's property, plant, and equipment (asset account) minus the accumulated depreciation (the contra asset account). It means the company's assets cost $150 million, the company has reported $120 million in depreciation expense over the years, and the company is now reporting the assets have a book value of $30 million.

It is possible for a company to have fully depreciated assets on its balance sheet. This means the company's estimate of the useful life of the asset was shorter than the asset's actual useful life. As a result, the asset - although it is still being used - is carried on the balance sheet at its salvage value.

This is a reminder that depreciation involves estimates and choices. It is not an infallible process.

Companies do not have cash layout for depreciation. Therefore, depreciation is added back in the cash flow statement.

Although depreciation is not a cash cost, it is a real business cost because the company has to pay for the fixed assets when it purchases them. Both Warren Buffett and Charlie Munger hate the idea of EDITDA because depreciation is not included as an expense. Warren Buffett even jokingly said We prefer earnings before everything when criticizing the abuse of EDITDA.


Be Aware

Depreciation estimates make the calculation of net income susceptible to management's accounting choices. These choices can be either overly aggressive or overly conservative.

Santos Business Description

Industry EnergyOil & Gas
Address 60 Flinders Street, Ground Floor Santos Centre, Adelaide, SA, AUS, 5000
Santos was founded in 1954. The company's name is an acronym for South Australia Northern Territory Oil Search. The first Cooper Basin gas discovery came in 1963, with initial supplies in 1969. Santos became a major enterprise, though over-reliance on the Cooper Basin, along with the Moomba field's inexorable decline, saw it struggle to maintain relevance in the first decade of the 21st century. However, the stage was set for a renaissance via conversion of coal seam gas into LNG in Queensland and conventional gas to LNG in PNG.
