NOTES: The current value is compared to the value from the same period in the previous year to account for seasonality.
The base period of the original index is December 1985. January 1992 is set to be the new reference point (=100) by dividing the values of the original index by the value of January 1992 in the original index. It is important to point out that this process changes only the reference point, and not the base period of the index because the weight structure of the index did not change.
Data from January 2002 to April 2002 are preliminary. Data for new, nonmilitary self-propelled ships was not available for November 2001.
