Year by year
| Fiscal year | ROIC | Read from |
|---|---|---|
| FY2017 The filed borrowings do not add up to a total we can stand behind: the filer's own liability subtotals leave room for debt we did not read. | n/a | 10-K, filed 2017-10-26 |
| FY2018 The filed borrowings do not add up to a total we can stand behind: the filer's own liability subtotals leave room for debt we did not read. | n/a | 10-K, filed 2018-10-15 |
| FY2019 | 18.9% | 10-K, filed 2019-10-17 |
| FY2020 | 7.0% | 10-K, filed 2020-10-19 |

| FY2024 | 1.5% | 10-K, filed 2024-10-04 |
| FY2025 | 13.7% | 10-K, filed 2025-10-03 |

How each year is computed
Operating income x (1 - effective tax rate) / (equity + total debt - cash) x 100
Each year is a ratio of lines in that year's filed annual report, with the nightly recompute's own rules for what counts as a filed line. Nothing is estimated, smoothed or filled in: a year that cannot be computed says why.
