Fixed a typo, new files attached:
Future contract delivery date sometime is same as last trading date (AUD
BBF, EuroDollar Futures (
Second London bank business day prior to the third Wednesday of the contract
month)),
or even after underlying index start date (NZ Bill Future). IMMDate is
underlying start date.
While last trading date (expiry date) is not used in curve construction,
it's roll-over date, and very important to maintain a curve.
For a future contract (whether used to construct curve), my view is that
it is important to model the last trading date, and way
to work out what is the underlying start date (last trading date + fixing).
Cheers,
Yan

The IMMDates are defined as the 3rd Wednesday of March, June,
September and December (or in a broader sense the 3rd Wednesday of any
month)
They are the delivery date of futures contracts on most (all?)
exchanges. What is the last trading date for each contract depends on
the contract, and generally speaking is not relevant for
bootstrapping, the delivery date being the relevant one
