Actual against the consensus estimate at the time. A flag marks a beat or a miss of more than 1.5% either way; inside that band the quarter is in line. A flag marked GAAP compares a GAAP figure the company reported with an adjusted consensus, two different measures, so a one-time gain or charge can move it either way. A flag reads n/a only when a number is missing. Quarterly EPS is the figure set against the consensus, usually adjusted, so the quarters need not add up to the 12-month net income per share above. An estimate is a forecast made by analysts, not a company target.

Since the trade is an estimate, set beside the S&P 500 over the same window, with the gap between the two in percentage points. The filing carries a band, not a fill, and a sale keeps the stock's sign, so a positive figure after a sale means the stock kept rising after it. An option row carries the underlying stock's move. A row marked n/a is one we hold no figure for.
A delay above 45 days is the gap between the dates on the report; we mark a filing late only after checking it.
"Not captured" means the band or the transaction type on the original report is missing from our data.
"Dates conflict" marks a row whose disclosure is dated before its trade on the record we hold. Both dates are printed as filed, and no since-the-trade figure is computed from them.

WHAT THE FILING ACTUALLY SAYS
