Construction Work-in-Progress

Construction work-in-progress, often abbreviated CIP, is a long-term asset account that collects every cost a company incurs while building an asset for its own use — materials, labor, architectural and engineering fees, permits, and capitalized interest on borrowed funds used to finance the project — from the moment construction begins until the asset is complete and ready for its intended use. It sits within property, plant and equipment on the balance sheet, but behaves differently from every other asset in that category while the project is underway.

An asset under construction is not yet generating any benefit for the business, so depreciation does not begin while costs sit in construction work-in-progress; depreciation only starts once the project is finished and the asset is placed into service, at which point the accumulated balance is transferred out of CIP and into the appropriate finished-asset account, such as Buildings or Equipment. Keeping construction costs in a separate account during the build phase makes this timing distinction easy to enforce and gives management, lenders, and auditors a clear, running total of how much capital has already been committed to a project that is not yet complete.

Direct construction costs are the obvious component, but accounting rules also require certain interest costs to be capitalized into CIP rather than expensed immediately, specifically the interest a company incurs on debt that can reasonably be attributed to financing the construction, calculated using the project's weighted-average accumulated expenditures over the construction period. This capitalized interest becomes part of the asset's total cost and is depreciated along with everything else once the project is finished, rather than reducing the current period's reported profit the way ordinary interest expense would.

A large or growing CIP balance that is not moving toward completion can be a warning sign: a stalled or abandoned project may need to be tested for impairment, since costs that were capitalized on the expectation of a completed, productive asset may no longer be recoverable if the project is unlikely to ever be finished. Analysts and lenders also watch CIP balances closely at capital-intensive companies — utilities, real estate developers, and manufacturers expanding their own plants — because a company can appear to have healthy current earnings while quietly accumulating enormous future depreciation and interest obligations tied up in projects still sitting in CIP.

Cash spent on construction work-in-progress appears in the investing section of the statement of cash flows as a form of capital expenditure, well before any of that spending shows up as an expense on the income statement through depreciation. This is one of the clearest illustrations of how a company's cash outflows and its reported profit can diverge sharply in a given period, since a business can be spending heavily on a multi-year construction project while its income statement, which only reflects completed and depreciating assets, shows comparatively little related cost until the project is finally finished.
