In the case of those pensioners who have foreign income in addition to the institution's pension payments, the exchange rate of those currencies is calculated in two ways. On the one hand, entitlements are calculated based on the so-called Á exchange rate (estimated exchange rate), and on the other hand, the year is settled based on the U exchange rate (settled exchange rate). The difference between this rate is as follows:

Á-exchange rate (estimated exchange rate) is the exchange rate used when the year's rights are calculated and is paid later in the year. But the estimated exchange rate is a forecast rate for the coming year, based on information from the Central Bank of Iceland about the exchange rate at the end of the previous year. That is, the estimated exchange rate for the year 2023 is based on information about the exchange rate of currencies at the end of 2022.

U-exchange rate (settlement exchange rate) is the exchange rate used when the year's entitlements are settled. But it looks at the middle rate (average selling and buying rate) of the year for the relevant currency when looking at the whole year according to information from the Central Bank of Iceland.
