Trailing twelve months
From Wikipedia, the free encyclopedia
In commerce, the trailing twelve months (TTM) is a moving measurement (for example, an average or a sum) over the 12 previous months, using the most recent data available.
Also sometimes known as last twelve months (LTM).
For example: if a Company reports $1m quaterly revenue in a 10-Q 1/1/2000, a $4m yearly revenue on 9/1/2000, and $10m quarterly revenue in 1/1/2001, the LTM revenue is calculated as $13m as follows.
Most Recent Quarter(s) + Most Recent Year - Oldest Quarters
$4m + $10m - $1m = $13m
