Appreciate some help from the experts.

Booked on SQ for SYD-SIN-BKK and return. The wholesaler said E fare basis but is it?

YEXT and YLEE35 as shown?

Endorsement / restrictions: VLD SQ ONLY NONREF NONCHNG WOUT REF TO ISS OFF

Fare calculation line:
SYD SQ SIN567.51YLEE35 SQ BKK209.97YEXT SQ SIN209.97YEXT SQ SYD567.50YLEE35 NUC1554.95END ROE1.209678 XT16.60SG27.10TS210.40YQ

I know to look at the great thread from qasr re earning on MP for *A fares, but want to be sure of the fare basis.

thanks,
