Some possibilities come to mind.
*) your data has changed significantly, and statistics are stale
*) your data has not changed, but statistics were run incorrectly and
confused the optimizer
*) your data has changed, statistics are current, but the data is now skewed
and the index
is no longer optimal
From your WHERE clause it appears that this export is a month-end process.
Could it be that a significant amount of data was added during April?
Just some things to consider.

Why not you create another table based on the rows meeting this criteria
and export the same.
