External Finance

External Finance

The External Finance Ratio is calculated as (Gross change in total assets for the year - net cash generated from operations) / Total assets at the end of the year.

If the ratio is positive (>0) it means that the company was not able to finance its assets growth from cash generated by its business. And if the ratio is negative (<0) it means that the company was able to generate enough cash to finance its assets growth.

This idea for this ratio came from the excellent book by Richard Tortoriello called Quantitative Strategies for Achieving Alpha: The Standard and Poor's Approach to Testing Your Investment Choices

All ratios are calculated on a trailing 12 months (TTM) basis.

This means the last twelve months (not the company’s financial year) is compared to the same period in the past. We do this to make sure that the screener data includes the latest, most up to date, financial results of the company.
