What it means
The most frequent business use is the acquisition premium, the difference between what a buyer offers for a company and what the market was already valuing it at. Buyers pay it because control, cost savings or strategic fit are worth more to them than to the average shareholder holding a few hundred shares.
A bond trades at a premium when its price is above face value, which happens when its fixed coupon is higher than the return currently available on comparable new bonds. The buyer pays extra today in exchange for above-market income for the remaining life of the bond.
In insurance the premium is the periodic payment the policyholder makes in return for the insurer carrying a risk. It is calculated from expected claims, administration costs and a profit margin, which is why premiums rise after a run of claims in a sector.
The word also appears in the phrase risk premium, meaning the extra return investors require for taking on more uncertainty. A corporate bond yielding 3 percentage points more than a government bond of the same maturity is offering a 3% credit risk premium.
The nuance is that a premium is always measured against something, so the number is meaningless without naming the reference point. A "40% premium" could be over yesterday's closing price, over a three-month average or over net asset value, and those can be very different figures.
In practice
Real-world examples.
Example
A listed retailer receives a takeover approach at $58 a share when the stock has been trading around $40. The board notes the 45% premium in its announcement, because shareholders judge the offer against the price they could otherwise sell at today.
Example
A pension fund buys an older corporate bond paying a 7% coupon in a market where new bonds of similar quality pay 5%. It pays a premium above face value, accepting that the price will drift back towards par as the bond approaches maturity.
Example
A logistics firm's fleet insurance premium rises 22% at renewal after two large claims. The broker explains that the increase reflects the firm's own claims record rather than a general market movement, and negotiates a higher excess to reduce it.
Think of it
“Premium is the extra amount paid-above the base price or standard value.
Formula
Calculation
Premium % = (price paid - reference value) / reference value x 100. Take an acquisition where the target's shares were trading at $40 before the announcement and the bidder offers $58 per share. The premium per share is 58 - 40 = $18, so the premium is 18 / 40 = 0.45, or 45%. The same formula works for bonds: if an investor pays $10,600 for a bond with a face value of $10,000, the premium is 10,600 - 10,000 = $600, which is 600 / 10,000 = 6% above par. Across 5,000,000 target shares, the 45% acquisition premium adds 18 x 5,000,000 = $90,000,000 to the total price paid.Case study
Seen in the real world.
Verity Home Supplies is a fictional listed homeware chain used here as an illustrative example. Its shares had traded near $40 for a year when a larger competitor announced an offer of $58 in cash, a 45% premium that the bidder justified by $30,000,000 of expected annual cost savings from combining distribution networks.
Several institutional shareholders argued the premium was measured against a depressed price and pointed to the $52 the shares had reached eighteen months earlier, which would have made the real premium closer to 12%. The board commissioned an independent valuation to settle which reference point was fair.
In this illustrative case the bidder raised its offer to $63 and the deal completed. The episode shows why the reference value matters as much as the premium percentage itself: the same offer can look generous or thin depending on which price you compare it with.
Watch out
Common mistakes.
- Quoting a premium without saying what it is a premium over. A percentage on its own is not interpretable until the reference price, book value or par value is stated.
- Assuming a large acquisition premium means the buyer overpaid. If the buyer can genuinely extract cost savings or revenue synergies, a high premium can still leave the deal creating value for its own shareholders.
- Believing a bond bought at a premium is a bad deal. The higher price simply reflects an above-market coupon, and the extra income over the bond's life is what the investor is paying for upfront.
Questions
People also ask.
Is an insurance premium the same concept as an acquisition premium?
Only loosely; the insurance sense means the price of cover, while the finance sense means an amount paid above a reference value.
What is the opposite of a premium?
A discount, meaning a price below the reference value, such as a bond trading below par or a fund trading below its net asset value.
Why do takeover premiums exist at all?
Because a controlling stake is worth more than a small holding, and because shareholders will not sell control without being paid more than the current market price.
