Template:Csa Valuation Date comp
The Valuation terms as between 1994 NY CSA and 1995 CSA didn’t change a great deal: here is a comparison. It got a bit more hinky with the arrival of the Modern CSAs: here’s a comparison between the 1995 and the 2016 VM CSAs.
Whereas the OG CSAs are kind of laissez faire — yo, dudes, put whatever you like in the elections para, you know — because a credit support annex back then was a bit of a wheeze, and no-one really understood it — in the intervening 21 years ISDA’s crack drafting squad™ got all nudgy.
So they say “every business day” unless you specify something else and, like, you are not going to specify something else, are you, because regulatory rules say it has to be every day.
Note also the introduction in 2016 of a Valuation Date Location: each party gets to choose one, being its own hometown. If you’re off dancing the maypole, or whatever collective cultural tradition you follow in your part of the world (In the Czech Republic, I am told, at Easter the boys chase the girls round the kitchen table with riding crops. Which sounds kind fun), then you should have no fear you’ll get called on to make a collateral transfer.
