jazzcharley, yes. You obviously reached 600 TPs in August 2014 and in doing so earned an update to silver for the rest of your current points year which ends 8 February as well as gaining silver from 8/2/15 until 8/2/16. Had you reached 600 points only on 7/2/15 you would have gained silver until 8/2/16 as well. Your exec card is always valid until the end of the month after your tier points are reset, hence for you, March 2016. Enjoy!
