Superficially things are quite different between the {{csa}} and the {{vmcsa}}, but this all boils down to the fact that the {{vmcsa}} is ''meant'' to be a zero-threshold, [[variation margin]]-only affair, so the concepts of {{csaprov|Independent Amount}} and {{csaprov|Threshold}}, both of which confuse the {{csa}}, aren’t there to get in the way. Unless you go and put them in anyway, as we shall see... | |||

Now, whether you have to ''pay'' anything or ''receive'' anything as a result — whether there is a {{csaprov|Delivery Amount}} or a {{csaprov|Return Amount}}, in other words — depends whether your {{csaprov|Credit Support Amount}} is greater or smaller than your prevailing {{csaprov|Credit Support Balance}}, by at least the {{csaprov|Minimum Transfer Amount}}. | Now, whether you have to ''pay'' anything or ''receive'' anything as a result — whether there is a {{csaprov|Delivery Amount}} or a {{csaprov|Return Amount}}, in other words — depends whether your {{csaprov|Credit Support Amount}} is greater or smaller than your prevailing {{csaprov|Credit Support Balance}}, by at least the {{csaprov|Minimum Transfer Amount}}. | ||

Never mind.
