FAQ

Where can I check these figures myself?

On SEC EDGAR, in CSX's 10-Q (accession 0000277948-26-000040). The same values appear on the corresponding lines of the consolidated statements.

Are the ratios figures the company reports?

No. They divide two figures stated in the filing for the same period. The working is in the arithmetic table in the subscriber section.

Are figures from different periods mixed?

No. Income and cash items are divided only by items covering the same length of time, and balances are always stated against the previous fiscal year-end.
