"Grants to U.S. eligible participants will be settled ... following the Reporting Person's termination date."

Termination date is the specific calendar day when a contract, agreement, option or other legal arrangement stops being in effect and any remaining rights or obligations expire. For investors it matters because that date sets deadlines for exercising rights, receiving payments, closing positions or avoiding penalties—similar to the day a lease or warranty ends, after which parties no longer have the same protections or claims.

What insider transaction did LAC director Walker Clayton report?

Director Walker Clayton reported receiving a grant of 6,900 Deferred Share Units (DSUs). These DSUs are a form of equity compensation linked to Lithium Americas common shares and increase his total reported DSU holdings to 6,900 units following the award.

What does each DSU represent for Lithium Americas Corp. (LAC)?

Each DSU represents the right to receive one common share of Lithium Americas. The actual common shares are only delivered after the director’s service ends, making DSUs a deferred, share-based form of compensation rather than immediate share ownership.

The DSUs are settled after the director’s termination. For U.S. eligible participants, settlement occurs six months after the termination date; for non-U.S. participants, it occurs on the 20th business day following the termination date, with no further action required.

What price was paid for the 6,900 LAC Deferred Share Units?

The 6,900 Deferred Share Units were granted at a price of $0.00 per unit. This indicates they were issued as a compensation award rather than purchased in the open market, and they are tied to future delivery of common shares.
