| Forward Contract Indexed to Issuer's Equity, Settlement Alternatives |
| us-gaap:ForwardContractIndexedToIssuersEquitySettlementAlternatives |
| Describe the settlement alternatives of the freestanding contract as either (i) physical settlement; (ii) net-share settlement; or, (iii) net-cash settlement. Physical settlement is when the party designated in the contract as the buyer delivers the full stated amount of cash to the seller, and the seller delivers the full stated number of shares to the buyer. Net-share settlement is when the party with a loss delivers to a party with a gain shares with a current fair value equal to the gain. Net-cash settlement is when the party with a loss delivers to the party with a gain a cash payment equal to the gain, and no shares are exchanged. Discuss also who controls the settlement alternatives and the maximum number of shares that could be required to be issued to net share settle a contract. If a contract does not have a fixed or determinable maximum number of shares that may be required to be issued, the fact that a potentially infinite number of shares could be required to be issued to settle the contract would generally be expected to be disclosed. |
