Thank you again Jaime. All your research is appreciated. Again, it just strengthens my case. Again, appreciate your time. Regards.

Thank you. As mentioned before, the only choices available were "as of" or "as at" (not "due on", "maturity on, "on", etc., etc.). All the proposals support my initial understanding and contention that the edits were incorrect and that "as of" could be misleading. Thank you all so much. HNY to all!

I very rarely (never?) use "as of" for the simple reason that it can be read, as you've said, in different ways and hence is not always clear in meaning. It seems to be used more frequently in US English as well. However, I see "as at"as being like a snapshot of a moment in time (the situation right now) so I think it could be used for "vigentes al" here though it's not really a time expression that is used that often to my knowledge. But I agree with Phil that it's much simpler just to use "on" in this particular case. Bit of discussion here: http://forum.wordreference.com/showthread.php?t=391810

Thanks very much. It proves my point, meaning that the "cut-off point" is on a particular day. "As of" could be interpreted "starting today and going forward into the future" (which is not the case). I will grade and close accordingly. Again thanks to all for your input. Regards.

..."al" means "on", doesn't it?
Using "as of" and "as on" seems to be confusing matters.

15:15 Jan 5, 2015 

Thank you. Let me see if I can use this example?
***Valor % Capitalizado al (as of/as at?) 31 Mar. 2002***

15:10 Jan 5, 2015 

I'm confused by your question, as you seem to be asking two completely different terms. Like you, I'm uncertain of the meaning of "vigentes al". But as Jaime says, "con vencimiento" is perfectly clear. It means "due" - not "due as of" or "due as at".

14:45 Jan 5, 2015 

Thank you. I appreciate your input. I understand "it is in force/due as of". However, the wording was very explicit and I am trying to prove or disprove as the case may be. Another example was:
Capitaliza hasta
Valor capitalizado al 3 Feb. 2002
Ajuste CER posterior al 3 Feb. 2002
***Valor % Capitalizado al 31 Mar. 2002***
Jaime, there are two choices only "as of" or "as at" (nothing more)! I understand "as of" and "as at" to mean two different things. Perhaps it is my "Britishness" coming out here, but I do need American English. Thanks.

"con vencimiento" = due as of (due date) / maturing on (maturity date) ...

14:24 Jan 5, 2015 

"vigentes al" = in force (on/at)/in effect (on/at)/existing (on/at) ... site ".gov" use more "on" than "at" on this context.
