The transaction codes in the recent window confirm this reading. 'S' codes (open-market sales) appear alongside 'A' codes (typically 401k or non-qualified deferred compensation purchases), 'M' codes (merger consideration or option exercise settlements), and a 'J' code (disposition of shares acquired through an option exercise). This mix is normal for a corporate insider: it reflects the mechanics of equity compensation — restricted stock vesting, option exercises, and periodic tax-driven sales — rather than discretionary portfolio decisions.

The total sell volume of 488,900 shares across 578 filings is large in the aggregate but modest on a per-transaction basis. The recent window shows sells of 3,000-6,000 shares at a time, priced around $113-115 per share — consistent with single-digit-percentage-of-holdings distributions rather than full position exits. Without access to the insider's total MGRC holding, we cannot calculate the remaining stake, but the persistence of sells over multiple years with no accompanying accumulation suggests the equity position is being managed down toward a target level rather than liquidated urgently.
