Covered Call Special Dividend Adjustment: What Happens to Your Options Contract

The Short Answer: Your Contract Gets Adjusted, Not Cancelled

When a company pays a special dividend, the Options Clearing Corporation (OCC) adjusts your covered call contract to keep the economics fair for both sides. The strike price drops by the special dividend amount, the deliverable may change, and your position stays open — but the numbers on your screen will look different the next morning.

This only applies to special (non-recurring) cash dividends above a threshold, not to ordinary quarterly dividends. Regular dividends are already priced into options through the cost-of-carry model, so the OCC leaves those contracts alone. Special dividends are surprises, and surprises require adjustments.

Why the OCC Steps In: The Rule Behind the Adjustment

The OCC is the central clearinghouse for all US-listed options. Under its rules, any special cash dividend of $0.125 per share or more triggers a mandatory contract adjustment effective on the ex-dividend date. The OCC publishes an information memo — called an OCC Memo — before the ex-date that spells out exactly how every open contract on that stock will be modified.

The logic is straightforward. When a stock pays a large special dividend, the share price drops by roughly the dividend amount on the ex-date. Without an adjustment, the call seller would benefit unfairly because the strike would suddenly be harder to reach. The OCC's adjustment restores the original risk-reward balance.

FINRA and the SEC both recognize OCC adjustments as standard market practice. If you hold options in a Canadian account through a broker that clears US-listed options, the same OCC rules apply to those contracts — the CRA may treat the resulting cost-basis changes differently, but the contract mechanics are identical.

Exactly What Changes in Your Covered Call

Three things can change after an OCC special dividend adjustment:

1. Strike price — The strike is reduced by the special dividend amount (rounded to the nearest $0.01 in most cases). If you sold a $180 call and the special dividend is $3.00, your new strike is $177.00.

2. Contract deliverable — In some cases, especially when the dividend is paid partly in stock or when the math creates an odd number, the OCC may adjust the deliverable to 100 shares plus cash, or change the number of shares per contract. This is less common for pure cash specials but worth checking the OCC Memo.

3. Open interest and ticker symbol — Adjusted contracts often get a new option symbol (sometimes called a "non-standard" or "adjusted" series). Liquidity in the adjusted series can be thin because market makers widen spreads on non-standard contracts.

What does NOT change: the expiration date, the number of contracts you hold, and your original premium received. You keep every dollar of premium you collected when you sold the call.

Worked Example: MSFT Special Dividend and a $185 Covered Call

Let's use a concrete scenario. Suppose you own 100 shares of Microsoft (MSFT) at a cost basis of $375 per share. You sold one covered call with a $385 strike expiring in 45 days and collected $4.20 per share ($420 total premium).

MSFT then announces a one-time special dividend of $3.00 per share, payable to shareholders of record, with an ex-dividend date in two weeks — before your option expires.

Here is what happens step by step:

- The OCC issues a memo confirming the $3.00 special dividend meets the $0.125 threshold. - On the ex-dividend date, MSFT's share price drops approximately $3.00 at the open, from $378 to roughly $375. - Your covered call strike adjusts from $385.00 down to $382.00. - Your 100 shares now receive $300 in special dividend cash (taxable — see the IRS section below). - Your covered call is now a $382 strike call on the adjusted contract series.

Net effect on your position: You collected $420 in premium (unchanged), you received $300 in dividend income, and your maximum gain if assigned is now capped at $382 minus your $375 cost basis, or $700 per contract — roughly the same dollar profit you would have had before the adjustment. The OCC did its job: the economics are preserved.

If MSFT had stayed at $378 and the strike had not adjusted, your $385 call would have been further out of the money, giving you an unearned windfall. The adjustment prevents that.

The Real Risks You Need to Know Before the Ex-Date

Adjustments sound clean on paper, but they create real practical problems for covered call writers.

Liquidity risk is the biggest one. Adjusted option series are non-standard. Bid-ask spreads widen dramatically — sometimes to $0.50 or more on a contract that traded at $0.05 wide before. If you want to buy back your call before expiration to close the position, you may pay a steep price to exit.

Early assignment risk rises around special dividends. Call buyers who are long deep-in-the-money calls may exercise early to capture the dividend themselves. If your call is in the money before the ex-date, there is a real chance you get assigned the night before the ex-date, which means you sell your shares and miss the special dividend entirely. The OIC (Options Industry Council) specifically flags early exercise around dividend dates as one of the most common surprises for covered call writers.

Tax complexity increases. The special dividend you receive is typically taxed as ordinary income or qualified dividend income depending on how long you have held the shares — the IRS rules on qualified dividends require a 60-day holding period around the ex-date. If your covered call has reduced your holding period (which it can under IRS straddle rules), the dividend may lose its qualified status. Consult a tax professional before assuming favorable treatment. Canadian investors should check CRA guidance on foreign dividend withholding and adjusted cost base rules.

Strike confusion. Some brokers display the adjusted strike correctly; others lag by a day or two. Always verify your position against the official OCC Memo, not just your brokerage platform.

How to Manage Your Position Around a Special Dividend Announcement

Once a special dividend is announced, you have a narrow window to act. Here are the practical choices:

Do nothing and let the adjustment happen. This is the default and often the right move if your call is out of the money and you are comfortable holding the adjusted contract to expiration. The economics are preserved by design.

Buy back the call before the ex-date. If your call is in the money and you are worried about early assignment, closing the position before the ex-date eliminates that risk. You give up the remaining time value but keep your shares and collect the special dividend. Use a limit order — do not use a market order on options, especially as ex-date approaches and spreads widen.

Roll the call. You can buy back the existing call and sell a new one in a standard (non-adjusted) series at a later expiration. This resets your position into a liquid contract and may let you capture more premium if implied volatility has risen on the news.

Do not sell a new covered call on the ex-date itself. The stock price drop on the ex-date is mechanical, not a signal. Selling a new call immediately after the price drops locks in a lower strike at a moment when the options market has already repriced everything. Wait at least one to two sessions for the dust to settle.

Tax Treatment of the Adjusted Contract and the Dividend

The premium you originally collected does not change, so there is no new tax event from the OCC adjustment itself. The adjustment is a contract modification, not a sale or exchange under IRS rules.

The special dividend, however, is a separate taxable event. The IRS treats most special cash dividends as ordinary dividends. Whether they qualify for the lower qualified dividend rate (0%, 15%, or 20% depending on your bracket) depends on the 60-day holding period rule and whether your covered call has suspended that holding period. Under IRS rules, a covered call that is deep in the money can be treated as a straddle, which stops the holding period clock. If you are close to the 60-day threshold, this matters.

For Canadian investors, the CRA requires you to report US special dividends as foreign income. A 15% US withholding tax typically applies under the Canada-US Tax Treaty, and you may claim a foreign tax credit. The adjusted cost base of your shares is not affected by the OCC contract adjustment itself, but the dividend receipt and any eventual assignment proceeds are separate ACB events.

Always keep the OCC Memo for your records. It is the official documentation of what changed and when, and your tax preparer will want it.

Does a regular quarterly dividend trigger an OCC adjustment on my covered call?

No. The OCC only adjusts contracts for special (non-recurring) cash dividends of $0.125 per share or more. Ordinary quarterly dividends are already reflected in options pricing through the cost-of-carry model, so no adjustment is made and your strike stays the same.

Will I still receive the special dividend if I have a covered call open?

Yes, as long as you still own the shares on the record date and have not been assigned early. Selling a covered call does not transfer dividend rights — you remain the shareholder. The risk is early assignment before the ex-date, which would cause you to sell your shares and miss the dividend.

How do I find the official OCC adjustment memo for my stock?

Go to the OCC's website and search the Infomemos section by ticker or date. The memo is published before the ex-dividend date and lists the exact new strike, deliverable, and effective date for every affected contract series. Your broker should also send a notification, but the OCC Memo is the authoritative source.

My broker is showing the old strike price after the adjustment — what should I do?

Some brokerage platforms lag by one to two business days in displaying adjusted contract details. Cross-reference your position against the official OCC Memo to confirm the correct strike and deliverable. If the discrepancy persists after two days, contact your broker's options desk directly.

Can I be assigned early on my covered call because of a special dividend?

Yes, and this is one of the most common surprises for covered call writers around special dividends. A call buyer who holds a deep-in-the-money call may choose to exercise early the night before the ex-date to capture the dividend themselves. The OIC specifically highlights early exercise around dividends as a key risk to monitor.

Does the OCC adjustment change my cost basis or my original premium received?

No. The OCC contract adjustment modifies the strike price and potentially the deliverable, but it does not alter the premium you already collected or your cost basis in the underlying shares. Those figures remain exactly as they were when you entered the trade.
