NR - Designates that the class was not rated by the rating agency.

(1) Changed ratings provided on this report are based on information provided by the applicable rating agency via electronic transmission. It shall be
understood that this transmission will generally have been provided to LaSalle within 30 days of the payment date listed on this statement. Because ratings may have
changed during the 30 day window, or may not be being provided by the rating agency in an electronic format and therefore not being updated on
this report, LaSalle recommends that investors obtain current rating information directly from the rating agency.
