and forward contracts. If a company decides to purchase an option, it is able to set a rate that is "at-worst" for the transaction. If the option expires and it's out-of-the-money, the company is able to execute the transaction in the open market at a favorable rate. If a company decides to take out a forward contract, it will set a specific currency rate for a set date in the future. Currency invoicing refers to the practice of invoicing transactions in the currency that benefits the firm. It is important to note that this does not necessarily eliminate foreign exchange risk, but rather moves its burden from one party to another. A firm can invoice its imports from another country in its home currency, which would move the risk to the exporter and away from itself. This technique may not be as simple as it sounds; if the exporter's currency is more volatile than that of the importer, the firm would want to avoid invoicing in that currency. If both the importer and exporter want to avoid using their own currencies, it is also fairly common to conduct the exchange using a third, more stable currency. If a firm looks to leading and lagging as a hedge, it must exercise extreme caution. Leading and lagging refer to the movement of cash inflows or outflows either forward or backward in time. For example, if a firm must pay a large sum in three months but is also set to receive a similar amount from another order, it might move the date of receipt of the sum to coincide with the payment. This delay would be termed lagging. If the receipt date were moved sooner, this would be termed leading the payment. Another method to reduce exposure transaction risk is natural hedging (or netting foreign-exchange exposures), which is an efficient form of hedging because it will reduce the margin that is taken by banks when businesses exchange currencies; and it is a form of hedging that is easy to understand. To enforce the netting, there will be a systematic-approach requirement, as well as a real-time look at exposure and a platform for initiating the process, which, along with the foreign cash flow uncertainty, can make the procedure seem more difficult. Having a back-up plan, such as foreign-currency accounts, will be helpful in this process. The companies that deal with inflows and outflows
