What the 2 currently disclosed positions would have been worth at each week’s closing price. A rising line means the shares got more valuable, not that this person bought more.

How the line is built

Share counts are as last reported to the SEC and held constant; only prices move.

Insider activity Mar 27, 2024 – Mar 23, 2026

Brian E Lane is recorded in filings to the U.S. SEC via EDGAR as officer and board member, and reported 84 transactions between Mar 27, 2024 and Mar 23, 2026. The buy and sell totals below count only codes P, S.

Why the other codes are excluded

Share awards (A), shares withheld to pay tax (F), option exercises (M) and gifts (G) also appear in the table, but they are consequences of a pay package or a private transfer, not a decision to buy or sell on the open market. Counting them would turn this into a compensation ranking.

Reported transactions

Price 0.00 is a real reported figure on gifts (G) and share awards (A) — not a missing number. The 25 most recent rows are grouped into 14 lines by date, company and transaction type — open a line to see every lot with its own source link. We hold 105 on file in total.

How to read this list

Every row is one line of one Form 4 or Form 5, with the filing it came from. Where the record carries no price at all we leave the cell empty instead of guessing one.

The shares and money on a grouped line add up only the lots listed inside that line, and only when every one of them carries the figure. Where a group mixes more than one reporting currency we leave the money blank rather than convert — no source publishes the rate that conversion would need.

Disclosed holdings

Shares is the amount on the form; value is that amount times the closing price shown. Rows with no closing price are left blank, so they may add up to less than the headline figure.

What is not counted here

Each row is one filing you can open. Private companies, real estate, bonds and crypto are not in SEC insider filings and are therefore not counted here.

Equity positions disclosed to the SEC, with the source filing behind each row.

Sharing a filing does not mean they work together day to day — it means both names appear on the same issuer’s insider record.
