pronunciation - Is there a regional preference for accenting the first syllable in "finance" vs. the second syllable?

I accent the first syllable in "finance", but I have a colleague who accents the second syllable. The debate in my office (which is strictly American) now falls between people who say accenting the second syllable is "the British way" and those who says it's the "hillbilly way".

I've seen this question (UK emphasis on the second syllable vs US emphasis on the first) that seems to indicate that "the British way" might be to accent the second syllable, and I saw that in this question too (First or second syllable accent for "detail"?).

Is there a regional distribution of these pronunciations? Is accenting the first syllable considered "American" and accenting the second syllable considered "British" or is it more nuanced than that? I only see the first pronunciation in MW. I think it's the first one at any rate, but dictionary.com appears to list both, with the version accented on the second syllable listed first.
