A company's valuation multiples over time — EV/Revenue, EV/EBIT, EV/EBITDA, P/E, Price/Sales and Price/Book recomputed point-in-time at each past quarter's filing date, oldest first (up to ~10 years); REITs also carry P/FFO and P/AFFO, and any filer with a verified reconciliation carries EV over its own stated Adjusted EBITDA, from the company's SEC-stated reconciliation as it existed at each sample date. Each sample uses only facts filed by that date and that day's raw close; a completed exact-primary split reconciliation preserves older samples, while anchors before an unresolved split are omitted. Absent ratios carry a machine-readable reason (evMissingReason / peMissingReason) instead of an estimate.

Sampled quarters dropped because no ratio was computable at that point in time or because the raw-close split basis was unprovable — non-zero means the series is shorter than the advertised ~10 years by this many anchors.

How many of the omitted anchors were dropped solely because they predate the company's latest unresolved split, where the stored raw-close basis cannot be proven against the current per-share basis; an exact-primary reconciliation preserves the older anchors (UnverifiedPriceSplitBasis). Always ≤ omittedAnchorCount.

REIT only: the company's verbatim label for the FFO measure behind priceToFfo (its own non-GAAP definition, from the newest priced sample). Null when no sample carries P/FFO.

REIT only: the company's verbatim label for the AFFO measure behind priceToAffo. Null when no sample carries P/AFFO.

The company's verbatim label for the Adjusted EBITDA measure behind evToAdjustedEbitda (its own non-GAAP definition, from the newest priced sample). Any filer with a verified reconciliation — no SIC gate. Null when no sample carries evToAdjustedEbitda.
