A collar is established by buying a share of stock for $46, buying a 6-month put option with exercise price
$43, and writing a 6-month call option with exercise price $49. On the basis of the volatility of the stock, you
calculate that for a strike price of $43 and expiration of 6 months, N(d₁) = .6974, whereas for the exercise
price of $49, N(d₁) = 0.6504.
