| c. | As of each balance sheet date, outstanding target redemption forward contracts not accounted for hedge accounting were as follows:
Currency |  | Maturity Period |  | Notional Amount (In Thousands)
December 31, 2021 |  |  |  |

The target redeemable forward contracts held by subsidiaries are weekly settled. If the market exchange rate is lower than the execution rate at the time of settlement, the contract will be settled at the nominal amount, whereas if the market exchange rate is higher than the execution rate, the contract will be settled at a leveraged nominal amount (twice the nominal amount). The contracts last until all the nominal amount of US$ position is fully settled. However, when the accumulated excess of the execution rates over the market exchange rates reach the agreed threshold after the weekly settlement, the contracts will be automatically early terminated.
