Special Case: Financial Abbreviations for Thousand and Million
Financial and accounting statements historically used a different approach to abbreviating thousand and million. This approach combines Roman numerals and abbreviations. It has become less common due to the potential for confusion. If you do use these abbreviations, be sure to clearly define them in the text.
M for Thousand
The Roman numeral for thousand is M, which is why it was used on financial statements to represent that quantity. However, since M is now used to abbreviate million, using the Roman numeral for thousand instead of a common abbreviation can lead to misunderstanding. Consider this example:
The company's financial statements indicated a $12M loss.
Readers could easily interpret this as a $12 million loss, though the financial professional might mean $12,000.
MM for Million
On financial statements that used M to indicate thousand, the common practice was to abbreviate million as MM. This is an abbreviation based on a calculation. It stands for 1000 times 1000 (which would calculate out to one million), this is abbreviated to M * M, but without the multiplication sign, thus becoming MM.
To add to the potential for misunderstanding, MM is not the Roman numeral for million. It is actually the Roman Numeral for 2,000. The Roman numeral for million is M with a line over it.
