The disclosure may include, but not be limited to: (i) the forward rate and the number of shares to which the contract is indexed, (ii) the settlement date or dates of the contract, (iii) the issuer's accounting for the contract, (iv) settlement alternatives (if applicable) including who controls the settlement alternatives and the maximum number of shares that could be required to be issued to net share settle the contract (if applicable), (v) the fact that a potentially infinite number of shares may be required to be issued to settle the contract, if a contract does not have a stated fixed or determinable maximum number of shares, and (vi) the contract's current fair value for each settlement alternative and how changes in the price of the issuer's equity instruments affect those settlement amounts.
