Trader Discounts Not Applied?

Looking at the Accounts, trader hourly costs and discounts are not accounted for here:

Income:
			City Population	?????
			City Gross Income	?????
			Current Tax Rate	??%
			Tax Collected	?????
Upkeep:
			Sovereignty	-?????
			Military in Barracks	-?????
			Military In Armies	-?????
			Spear discount (0.0%) approx	0
			Ranged discount (30.0%) approx	0
			Infantry discount (0.0%) approx	0
			Cavalry discount (0.0%) approx	0
			Diplomatic in Consulate	-?????
			Diplomatic In Armies	0
			Scout discount (0.0%) approx	0
			Spy discount (0.0%) approx	0
			Thief discount (30.0%) approx	0
			Saboteur discount (0.0%) approx	0
			Assassin discount (0.0%) approx	0
			Sub total	-?????
			Total	?????
Alliance:
			Tax Rate	0%
			Tax Amount	0
			City Net Income	?????

But the cost of the trader(s) seems to disappear someplace after the "City Net Income" and before the gold displayed on the resource bar.  What seems to never be applied are the trader upkeep discounts (from research for "Trader Luxuries", "Expense Accounts" and "Expense Controls").  Can anyone verify this for their accounts?
