INTRODUCTION

Option exercise limits, along with position limits (See KB1252), have been in place since the inception of standardized trading of U.S. securities options. Their purpose is to prevent manipulative actions in underlying securities (e.g., corners or squeezes) as well as disruptions in option markets where illiquidity in a given option class exists.  These limits serve to prohibit an account, along with its related accounts, from cumulatively exercising within any five consecutive business day period, a number of options contracts in excess of the defined limit for a given equity options class (i.e., option contracts associated with a particular underlying security). This includes both early exercises and expiration exercises.

OVERVIEW

U.S. securities option exercise limits are established by FINRA and the U.S. options exchanges.  The exercise limits are generally the same as position limits and they can vary by option class as they take into consideration factors such as the number of shares outstanding and trading volume of the underlying security. Limits are also subject to adjustment and therefore can vary over time.  The Options Clearing Corporation (OCC), the central clearinghouse for U.S. exchange traded securities options, publishes a daily file with these limits on its public website. The link is as follows: http://www.optionsclearing.com/webapps/position-limits.  FINRA Rule 2360(b)(4) addresses exercise limits and can be found via the following website link: http://finra.complinet.com/en/display/display.html?rbid=2403&record_id=16126&element_id=6306&highlight=2360#r16126).

Note that exercise limits are applied based upon the the side of the market represented by the option position. Accordingly, all exercises of call options over the past five business days are aggregated for purposes of determining the limit for the purposes of purchasing the underlying security.  Similarly, a separate computation whereby all put exercises over the past five business days are aggregated is required for purposes of determining sales of the underlying.

IMPORTANT INFORMATION

It's important to note that while exercise limits may be set at levels identical to position limits, it is possible for an account holder to reach an exercise limit without violating positions limits for a given option class.  This is because exercise limits are cumulative and one could conceivably purchase options up to the position limit, exercise those options and purchase additional options which, if allowed to be exercised within the five business day window, would exceed the limit.

Account holders are responsible for monitoring their cumulative options exercises as well as the exercise limit quantities to ensure compliance.  In addition, IB reserves the right to prohibit the exercise of any options, regardless of their intrinsic value or remaining maturity, if the effect of that exercise would be to violate the exercise limit rule.

INTRODUCTION

Exercising an equity call option prior to expiration ordinarily provides no economic benefit as:

• It results in a forfeiture of any remaining option time value;
• Requires a greater commitment of capital for the payment or financing of the stock delivery; and
• May expose the option holder to greater risk of loss on the stock relative to the option premium.

Nonetheless, for account holders who have the capacity to meet an increased capital or borrowing requirement and potentially greater downside market risk, it can be economically beneficial to request early exercise of an American Style call option in order to capture an upcoming dividend.

BACKGROUND

As background, the owner of a call option is not entitled to receive a dividend on the underlying stock as this dividend only accrues to the holders of stock as of its dividend Record Date. All other things being equal, the price of the stock should decline by an amount equal to the dividend on the Ex-Dividend date. While option pricing theory suggests that the call price will reflect the discounted value of expected dividends paid throughout its duration, it may decline as well on the Ex-Dividend date.  The conditions which make this scenario most likely and the early exercise decision favorable are as follows:

1. The option is deep-in-the-money and has a delta of 100;

2. The option has little or no time value;

3. The dividend is relatively high and its Ex-Date precedes the option expiration date. 

EXAMPLES

To illustrate the impact of these conditions upon the early exercise decision, consider an account maintaining a long cash balance of $9,000 and a long call position in hypothetical stock “ABC” having a strike price of $90.00 and time to expiration of 10 days. ABC, currently trading at $100.00, has declared a dividend of $2.00 per share with tomorrow being the Ex-Dividend date. Also assume that the option price and stock price behave similarly and decline by the dividend amount on the Ex-Date.

Here, we will review the exercise decision with the intent of maintaining the 100 share delta position and maximizing total equity using two option price assumptions, one in which the option is selling at parity and another above parity.

SCENARIO 1: Option Price At Parity - $10.00
In the case of an option trading at parity, early exercise will serve to maintain the position delta and avoid the loss of value in long option when the stock trades ex-dividend, to preserve equity. Here the cash proceeds are applied in their entirety to buy the stock at the strike, the option premium is forfeited and the stock (net of dividend) and dividend receivable are credited to the account.  If you aim for the same end result by selling the option prior to the Ex-Dividend date and purchasing the stock, remember to factor in commissions/spreads:

SCENARIO 2: Option Price Above Parity - $11.00
In the case of an option trading above parity, early exercise to capture the dividend may not be economically beneficial. In this scenario, early exercise would result in a loss of $100 in option time value, while selling the option and buying the stock, after commissions, may be less beneficial than taking no action. In this scenario, the preferable action would be No Action.

NOTE:

Options have two components that make up their total premium value - intrinsic value and time value. The intrinsic value is the amount by which the option is in-the-money, while the time value represents the possibility that the option could become even more profitable before expiration as the underlying asset price fluctuates while providing protection against adverse moves.

Many options are American-style, which means they can be exercised early, ahead of their expiration date. Early exercise of an option eliminates the remaining time value component from the option's premium, since the option holder loses protection against unfavorable movements in the underlying asset’s price.

This makes early exercise suboptimal in most situations, as the option holder is willingly forfeiting a portion of the option's value.

There are a few specific circumstances where early exercise could make sense, such as:

• For call options on a stock that will pay dividends soon, where the dividend amount exceeds the remaining time value (and only if the exercise will settle on or prior to the record date for the dividend).
• For deep in-the-money options where the time value is negligible compared to the intrinsic value, and the option is expected to drop in value due to interest rate effects (PUTS), or expected stock loan benefits (CALLS).

The first case, exercising an in the money call immediately ahead of a dividend payment, is the most common economically-sensible early exercise. In most cases, it is advisable to hold or sell the option instead of exercising it early, in order to capture the remaining time value. An option should only be exercised early after carefully considering all factors and determining that the benefits of early exercise outweigh the time value being surrendered.

Account holders holding a long call position as part of a spread should pay particular attention to the risks of not exercising the long leg given the likelihood of being assigned on the short leg.  Note that the assignment of a short call results in a short stock position and holders of short stock positions as of a dividend Record Date are obligated to pay the dividend to the lender of the shares. In addition, the clearinghouse processing cycle for exercise notices does not accommodate submission of exercise notices in response to assignment.

As example, consider a credit call (bear) spread on the SPDR S&P 500 ETF Trust (SPY) consisting of 100 short contracts in the March '13 $146 strike and 100 long contracts in the March '13 $147 strike.  On 3/14/13, with the SPY Trust declared a dividend of $0.69372 per share, payable 4/30/13 to shareholders of record as of 3/19/13. Given the 3 business day settlement time frame for U.S. stocks, one would have had to buy the stock or exercise the call no later than 3/14/13 in order receive the dividend, as the next day the stock began trading Ex-Dividend. 

On 3/14/13, with one trading day left prior to expiration, the two option contracts traded at parity, suggesting maximum risk of $100 per contract or $10,000 on the 100 contract position. However, the failure to exercise the long contract in order to capture the dividend and protect against the likely assignment on the short contracts by others seeking the dividend created an additional risk of $67.372 per contract or $6,737.20 on the position representing the dividend obligation were all short calls assigned.  As reflected on the table below, had the short option leg not been assigned, the maximum risk when the final contract settlement prices were determined on 3/15/13 would have remained at $100 per contract.

Please note that if your account is subject to tax withholding requirements of the US Treasure rule 871(m), it may be beneficial to close a long option position before the ex-dividend date and re-open the position after ex-dividend.

The above article is provided for information purposes only as is not intended as a recommendation, trading advice nor does it constitute a conclusion that early exercise will be successful or appropriate for all customers or trades. Account holders should consult with a tax specialist to determine what, if any, tax consequences may result from early exercise and should pay particular attention to the potential risks of substituting a long option position with a long stock position.

Under Section 31 of the Securities Exchange Act of 1934, U.S. national securities exchanges are obligated to pay transaction fees to the SEC based on the volume of securities that are sold on their markets. Exchange rules require their broker-dealer members to pay a share of these fees who, in turn, pass the responsibility of paying the fees to their customers.

This fee is intended to allow the SEC to recover costs associated with its supervision and regulation of the U.S. securities markets and securities professionals. It applies to stocks, options and single stock futures (on a round turn basis); however, IB does not pass on the fee in the case of single stock futures trades.  Note that this fee is assessed only to the sale side of security transactions, thereby applying to the grantor of an option (fee based upon the option premium received at time of sale) and the exerciser of a put or call assignee (fee based upon option strike price).

For the fiscal year 2016 the fee was assessed at a rate of $0.0000218 per $1.00 of sales proceeds, however, the rate is subject to annual and,in some cases, mid-year adjustments should realized transaction volume generate fees sufficiently below or in excess of targeted funding levels.¹

Examples of the transactions impacted by this fee and sample calculations are outlined in the table below.
