Real Exports and Real Imports released today reflect the regular update in their seasonal adjustment, which takes place every year, usually after the release of the retroactive revisions to the figures in the "Trade Statistics" for the previous calendar year. Please note that the figures have been revised from the starting periods. The X-12-ARIMA specifications are the same as the previous ones.

For details on the compilation method of Real Exports and Real Imports, see Explanation of "Developments in Real Exports and Real Imports."
