Margins
? A margin is cash or marketable
securities deposited by an investor with
his or her broker
? The balance in the margin account is
adjusted to reflect daily settlement
? Margins minimize the possibility of a
loss through a default on a contract

Other Key Points About Futures
? They are settled daily
? Closing out a futures position
involves entering into an
offsetting trade
? Most contracts are closed out
before maturity
Options,Futures,and Other Derivatives,5th edition ? 2002 by John C,Hull
2.7
Delivery
? If a contract is not closed out before maturity,
it usually settled by delivering the assets
underlying the contract,When there are
alternatives about what is delivered,where it
is delivered,and when it is delivered,the
party with the short position chooses.
? A few contracts (for example,those on stock
indices and Eurodollars) are settled in cash

contracts outstanding

final bell each day

Questions
? When a new trade is completed
what are the possible effects on
the open interest?
? Can the volume of trading in a day
be greater than the open interest?
Options,Futures,and Other Derivatives,5th edition ? 2002 by John C,Hull
2.11
Regulation of Futures
? Regulation is designed to
protect the public interest
? Regulators try to prevent
questionable trading practices
by either individuals on the floor
of the exchange or outside
groups

2.12Accounting & Tax
? If a contract is used for
– Hedging,it is logical to recognize
profits (losses) at the same time as on
the item being hedged
– Speculation,it is logical to recognize
profits (losses) on a mark to market
basis
? Roughly speaking,this is what the
treatment of futures in the U.S.and many
other countries attempts to achieve
