Securities Analyst

TL;DR Small incremental share accrual for director compensation; immaterial to company capitalization or investor valuation.

The transaction recorded is the grant/accrual of 12 deferred stock units (1-for-1 settlement to common stock) for a director, increasing reported beneficial ownership to 5,686 shares. The trustee-held 157 shares are disclosed as indirect ownership. There are no purchases or sales of existing shares, no option exercises, and no price per share reported for non-derivative holdings. Impact on outstanding shares or control is negligible given the size.
