10A00.              SCOPE OF CHAPTER

This chapter is limited in application to put and call options on Corn futures contracts. In addition to the rules of this chapter, transactions in options on Corn futures shall be subject to the general rules of the Exchange insofar as applicable. (11/29/07)

10A01.              OPTIONS CHARACTERISTICS 

10A01.A.           Contract Months

Trading may be conducted in the nearby Corn futures options contract month and any succeeding months, provided however, that the Exchange may determine not to list a contract month. For options that are traded in contract months in which Corn futures are not traded, the underlying futures contract is the next futures contract that is nearest to the expiration of the option. For example, the underlying futures contract for the February option contract is the March futures contract. (11/29/07)

10A01.B.           Trading Unit                    

One 5,000 bushel Corn futures contract of a specified contract month. (11/29/07)

10A01.C.           Minimum Fluctuations

The premium for Corn futures options shall be in multiples of one‑eighth (1/8) of one cent per bushel of a 5,000 bushel Corn futures contract which shall equal $6.25 per contract.

However, a position may be initiated or liquidated in Corn futures options at a premium ranging from $1.00 to $6.00 in $1.00 increments per option contract. (11/29/07)

10A01.D.           Trading Hours

The hours of trading for options on Corn futures contracts shall be determined by the Exchange.  Corn futures options shall be opened and closed for all months and strike prices simultaneously.

On the last day of trading in an expiring option, the expiring Corn futures options shall be closed with a public call, made strike price by strike price, immediately following the close of the open outcry trading session for the corresponding Corn futures contract. (11/29/07)

10A01.E.           Exercise Prices                

Trading shall be conducted for put and call options with striking prices in integral multiples of five (5) cents and ten (10) cents per bushel per Corn futures contract as follows:

1.        

a.       At the commencement of trading for any option contract, the Exchange shall list a strike closest to the previous day's settlement price of the underlying Corn futures contract (the at-the-money strike), and strikes in integral multiples of ten cents in a range 50 percent above and below the at-the-money strike. If the previous day's settlement price is midway between two strikes, the at-the-money strike shall be the larger of the two. 

b.       Over time, new ten cent strikes will be added to ensure that all strikes within 50 percent of the previous day's settlement price in the underlying futures contract are listed.

2.        

a.       At the commencement of trading for options that are traded in months in which Corn futures are not traded, and for standard option months the business day they become the second listed month, the Exchange shall list a strike closest to the previous day's settlement price of the underlying Corn futures contract (the at-the-money strike), and strikes in integral multiples of five cents in a range of 25 percent above and below the at-the-money strike. If the previous day’s settlement price is midway between two strikes, the at-the-money strike shall be the larger of the two. For example, five-cent strike price intervals for the September contract would be added on the     first business day after the expiration of the July options contract.

b.       Over time, new five-cent strike prices will be added to ensure that all strikes within 25 percent of the previous day's settlement price in the underlying futures are listed.

3.       All strikes will be listed prior to the opening of trading on the following business day.  The Exchange may modify the procedures for the introduction of strikes as it deems appropriate in order to respond to market conditions.  The Exchange will not generally consider new strike prices beyond the strike bands described above. (4/28/08)

In accordance with Rule 559, Position Limits and Exemptions, no person shall own or control Corn futures and options positions in excess of:

1.      600 futures contracts net long or net short in the spot month. 

2.      13,500 futures-equivalent contracts net long or net short in any single contract month excluding the spot month. Additional futures contracts may be held outside of the spot month as part of futures/futures spreads within a crop year provided that the total of such positions, when combined with outright positions, does not exceed the all months combined limit.

3.      22,000 futures-equivalent contracts net long or net short in all months combined.

The buyer of a Corn futures option may exercise the option on any business day prior to expiration by giving notice of exercise to the Clearing House by 6:00 p.m., or by such other time designated by the Exchange, on such day.

After the close on the last day of trading, all in-the-money options shall be automatically exercised unless notice to cancel automatic exercise is given to the Clearing House. Notice to cancel automatic exercise shall be given to the Clearing House by 6:00 p.m., or by such other time designated by the Exchange, on the last day of trading.

Exercise notices accepted by the Clearing House shall be assigned through a process of random selection to clearing members’ open short positions in the same series. A clearing member to which an exercise notice is assigned shall be notified of the assignment as soon as practicable after such notice is assigned by the Clearing House.

The clearing member assigned an exercise notice shall be assigned a short position in the underlying futures contract if a call is exercised or a long position in the underlying futures contract if a put is exercised. The clearing member representing the option buyer shall be assigned a long position in the underlying futures contract if a call is exercised or a short position in the underlying futures contract if a put is exercised. All such futures positions shall be assigned at a price equal to the exercise price of the option and shall be marked to market in accordance with Rule 814 on the trading day of acceptance by the Clearing House of the exercise notice.
