Covered calls and dividends

The one time early assignment stops being theoretical is the day before an ex-dividend date. A call holder who exercises then captures the dividend, and they will do it whenever the dividend is worth more than the time value they give up. If you own the shares on ex-div, you get the dividend. If you were assigned the day before, you do not.

American-style equity options can be exercised on any business day, and almost nobody does it early, because exercising throws away the option's remaining time value. Dividends are the exception that makes the whole thing worth understanding.

The condition, stated precisely

A call holder exercises early to capture a dividend when the dividend exceeds the remaining extrinsic value of the call. Exercising converts the option into shares, which means giving up whatever time value the option still carries. If the dividend is bigger than that time value, exercising is the profitable move.

This means early assignment risk concentrates on deep in-the-money calls with little time value left, just before an ex-dividend date. A far out-of-the-money call is never exercised for a dividend, because it has no intrinsic value to convert.

How to see it coming

Two numbers, the day before ex-div.

• The dividend. Say KO goes ex-dividend for $0.51.
• The extrinsic value of your short call. Take the call's price and subtract its intrinsic value. If your $75 call trades at $3.10 with the stock at $77.90, intrinsic is $2.90 and extrinsic is $0.20.

$0.51 of dividend against $0.20 of time value. Exercising early is worth $0.31 a share to the holder, so expect to be assigned. If instead the call had $0.90 of extrinsic value, exercising would cost the holder more than the dividend and you would probably keep the shares.

This is not a certainty in either direction. OCC / Options Industry Council, Options Exercise FAQ confirms that assignment is allocated randomly among clearing members and then to their customers, so you can be assigned when the arithmetic says you should not be, and skipped when it says you should.

What it costs you

Assigned the day before ex-div, you lose the dividend and the shares at once. On 200 shares of KO that is $102 of dividend you had already counted on, plus whatever the call cost you in capped upside.

The defence is not complicated. Check the ex-dividend calendar before you write, and look at your short call's extrinsic value in the days before ex-div. If time value has collapsed below the dividend and you want to keep the shares, buy the call back before the close the day before ex-div.

The tax wrinkle most people miss

Getting the dividend is not the same as getting a qualified dividend, taxed at the lower long-term rate. Qualified treatment requires holding the shares more than 60 days during the 121-day window that begins 60 days before the ex-dividend date.

Writing an in-the-money covered call that fails the qualified covered call test suspends that holding period while the call is open, per IRS Publication 550, Investment Income and Expenses. At-the-money and out-of-the-money qualified covered calls do not.

The practical consequence: writing deep in-the-money calls against a dividend payer can quietly convert your qualified dividends into ordinary income. On a large position the tax difference can exceed the premium you collected. The rules have real specificity about strike distance and time to expiry, this page is not tax advice, and this is a genuinely good reason to talk to an accountant if you are writing in-the-money calls on income positions.

The simple version

• Own the shares on the ex-dividend date, collect the dividend.
• Deep in-the-money short calls before an ex-div date are the highest early assignment risk in this strategy.
• Compare the dividend against your call's remaining time value. That comparison is the whole forecast.
• Out-of-the-money calls on dividend payers are largely fine, and are what most covered call sellers write anyway.
