2  As a result of the revision to seasonal adjustments carried out in April 2010, it is likely that a portion of the significant drops in production in the October-December quarter of 2008 and the January-March quarter of 2009 is recognized as seasonal rather than actual movement.
Such a seasonal adjustment method would push up future growth rates for the October-December and January-March quarters, but push down those for the April-June and July-September quarters. Therefore, it is necessary to assess actual terms for the AprilJune and July-September quarters by adjusting for such downward pressure.
