Sorry to jump back into an old thread, Steve, but could you give me a real world example of this series vs parallel tax business? Series I see as the purchaser paying Fed+State+local. But parallel? Do you mean this in a tax reporting context?

>In our case, behind the scenes, we instantiate separate implementation objects for municipal, state, and federal taxes, and these get combined in series or in parallel depending on whether taxes are additive or whether they piggyback.
