Insights

Financial Analyst

TL;DR: Insider reported a 200-share donation, reducing beneficial holdings to 5,287 shares; transaction appears non-sale and non-cash.

The Form 4 discloses a non-cash disposition coded G(1) that the filer explains as a donation to a charitable account. Because the transaction is a gift, no cash proceeds are reported and the entry lists a price of $0. The remaining beneficial ownership is explicitly stated as 5,287 shares. The filing provides straightforward disclosure of the change in ownership but contains no financial details about total insider stake percentage or company-wide share counts, so materiality to the cap table cannot be assessed from this form alone.

Corporate Governance Expert

TL;DR: Proper Section 16 disclosure of a charitable disposition; documentation and signature by attorney-in-fact noted.

The report uses the G(1) transaction code and includes an explicit explanation identifying the recipient as a Fidelity Charitable Giving Account, which aligns with Rule 16 reporting for gifts. The filing notes that a power of attorney was used and is on file with the Commission, and it is signed by the attorney-in-fact. The form meets standard disclosure elements: reporting person identity, relationship to issuer, transaction date, amount disposed, post-transaction holdings, and explanation. No governance concerns or corrective amendments are indicated within this document.
