Delivery month

For futures contracts specifying physical delivery, the delivery month is the month in which the seller must deliver, and the buyer must accept and pay for, the underlying. For contracts specifying cash settlement, the delivery month is the month of a final mark-to-market. The exact dates of acceptable delivery vary considerably and will be specified by the exchange in the contract specifications.

For most futures contracts, at any given time, one contract will typically be traded much more actively than others. This is called variously the front month or the top step contract.

Financial contracts (such as bonds, short term interest rates, foreign exchange and stock indexes) tend to expire quarterly, in March, June, September and December.

This table lists the conventional letter codes used in tickers to specify delivery month:

Month Codes

Month	Code
January	F
February	G
March	H
April	J
May	K
June	M
July	N
August	Q
September	U
October	V
November	X
December	Z

To name a specific contract in a financial futures market, the month code will follow the contract code, and in turn be followed by the year. For example, CLZ8 is the December 2008 NYMEX crude oil contract. CL denotes crude oil (crude light), Z corresponds to the December delivery month, and 8 refers to 2008.
