Why are dividends important for determining
index arbitrage conditions?
 The fair value premium equals the interest
earned on the spot index minus dividends
earned by the stocks that comprise the index.
The relevant time period is from the current
date until the future's expiration.
 As you might imagine, controversy exists about how to implement the above equation: some arbitrageurs
measure dividends by yield; others (correctly in our opinion) by amount.
 Both measures are presented here.
