deferred acquisition costs

Selling a policy costs a lot up front — the agent's commission, medical underwriting, and paperwork all land in year one — but the policy is meant to earn money slowly over many years. If you charged all that cost against the first year's books, a healthy growing insurer would look like it was haemorrhaging money simply because it sold a lot of good new policies. Deferred acquisition costs (DAC) are the accounting device that spreads those big upfront selling costs over the years the policy is expected to stay in force, matching the cost to the income it helps generate.

Precisely, instead of expensing all acquisition costs immediately, the insurer capitalizes the recoverable portion as an asset on its balance sheet — the DAC asset — and then amortizes (writes it off gradually) over the life of the business, typically in proportion to premiums or to expected profits (gross profits or gross margins, depending on the accounting regime). Each year a slice of the DAC is released as an expense, so the heavy year-one outlay is smoothed into a steadier cost. This is the accounting mirror image of new-business strain and of why modified reserves were created.

DAC matters because it is often one of the largest assets on a life insurer's books and a major driver of reported earnings, especially for fast-growing companies. It is also fragile: if policyholders lapse faster than expected, the remaining DAC may not be recoverable and must be written down ('DAC unlocking' or impairment), which can hit earnings hard. An honest caveat — a DAC asset is not cash; it is the right to recover past spending out of future profits, and it evaporates if those future profits do not materialize.
