What insider transactions did PACCAR (PCAR) report for director Luiz Antonio Dos Santos Pretti?

PACCAR reported that director Luiz Antonio Dos Santos Pretti had other transactions in stock units, not open-market buys or sells. These involved adjustments and dividend reinvestments in deferred phantom and restricted stock unit accounts tied to PACCAR common stock under a non-employee director plan.

How many PACCAR stock units were affected in the latest Form 4 for PCAR?

The filing shows 3.5987 stock units credited in one deferred account and 11.1429 stock units credited in a Restricted Stock and Deferred Compensation Plan account. These changes reflect other transactions and dividend reinvestments rather than traditional share purchases or sales in the open market.

What is the PACCAR Restricted Stock and Deferred Compensation Plan (RSDCP) mentioned in the PCAR Form 4?

The RSDCP is a plan for PACCAR non-employee directors that uses phantom and restricted stock units. These units track PACCAR common stock on a 1-for-1 basis and can convert into shares upon termination or after vesting, with dividends reinvested into additional units according to plan terms.

Did the PACCAR director buy or sell PCAR common stock in this Form 4 filing?

The Form 4 describes the transactions as “other acquisition or disposition” in stock units, not standard buys or sells of common shares. The activity primarily reflects dividend reinvestments and adjustments within deferred and restricted stock unit accounts under PACCAR’s non-employee director compensation plan.

How many PACCAR stock units does the director hold after these transactions?

After these reported transactions, one deferred stock unit account shows 1,365.8654 units and the Restricted Stock and Deferred Compensation Plan account shows 4,229.2487 units. Both sets of units are ultimately tied to PACCAR common stock on a 1-for-1 basis under the plan’s conditions.

What does the 1-for-1 conversion feature mean for PACCAR stock units in this Form 4?

The 1-for-1 feature means each phantom or restricted stock unit can convert into one share of PACCAR common stock when plan conditions are met. For non-employee directors, conversion generally occurs upon termination or after vesting, with interim dividends reinvested into additional units per the plan.
