Final Price - Equity Derivatives Provision
Template:Eqderivanat Note that Final Price isn't necessary the final Final Price: you determine a fresh Final Price on every Valuation Date, as of the Valuation Time, and they feed into the Cash Settlement (or Equity Notional Reset) process, whereby one party pays out the movement price of the underlier over the period since the last Valuation Date.
Thus, Final Price for today’s Valuation Date becomes the Initial Price for the next Valuation Date, and so on and so on — yesterday’s rooster is today’s feather duster so to say.
Only on the final Final Price does the Transaction terminate and that contingency — you know, calling it quits and wrapping the whole thing up — isn’t addressed in any particular way in the definitions booklet, the presumption being that you will just follow the same procedure as you would for any other Valuation Date on the last one. This might give your US Tax guy the heebie-jeebies, be warned, as he will want VWAP, or some kind of hypothetical broker dealer referenced in the very last one. Dash cold water in his face if so, and tell him to get it together, man.
On the difference between Final Price and Relevant Price
Final Price is defined in Article 5 of the 2002 ISDA Equity Derivatives Definitions and is germane therefore to Equity Swap Transactions only and not, say, Forward Transactions (which, circuitously, rely instead on Relevant Price, albeit defined in a similar way).
The Final Price also has separately broken-out scenarios for Basket Transactions (being just the weighted sums of the individual components in the basket). Relevant Price doesn't bother to break these out — whether that is a function of the fact that Share Basket Forwards behave differently to Basket Swaps, or just because the drafting committee was losing the will to live, is a question to which we have yet to get to the bottom.
Don’t hold your breath.
