Last Twelve Months (LTM)

What it is:

Last twelve months (LTM), also known as trailing twelve months (TTM), is the 12-month interval occurring before a given point in time. 

How it works (Example):

For example, an analyst who is issuing a report on October 15, 2012 will report last twelve months (LTW) earnings as those from October 1, 2011 to September 30, 2012. 

Why it Matters:

Analysts and policymakers frequently use the last twelve months to gauge economic performance and to analyze data from the past year. It is important not to confuse the last twelve months with the last fiscal year (LFY), which covers the organization's most recently-completed fiscal year.
