FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What insider transaction did Cohu (COHU) report for Klaus Ilgenfritz?

Cohu reported that executive Klaus Ilgenfritz had 998 shares of common stock automatically withheld. The withholding covered tax obligations triggered by the vesting of restricted stock units in a transaction exempt under Rule 16(b)-3, rather than an open-market sale.

Was the Cohu (COHU) insider transaction an open-market sale of shares?

No, the transaction was not an open-market sale. 998 shares were automatically withheld upon vesting of restricted stock units solely to cover tax obligations in a Rule 16(b)-3 exempt transaction, meaning it reflects tax compliance rather than discretionary selling activity.

How many Cohu (COHU) shares does Klaus Ilgenfritz hold after this transaction?

After the tax-withholding disposition, Klaus Ilgenfritz holds 100,314 shares of Cohu common stock directly. This total includes both currently held shares and restricted stock units that are reported as part of his position in the filing.

What restricted stock unit (RSU) holdings are disclosed for Cohu (COHU) executive Klaus Ilgenfritz?

The filing notes that his holdings include 82,630 restricted stock units. These RSUs are expected to convert into Cohu common stock on a one-for-one basis upon future vesting dates, subject to continued service and achievement of specified performance goals.

Why were 998 Cohu (COHU) shares withheld for Klaus Ilgenfritz?

The 998 shares were withheld automatically when his restricted stock units vested. The shares covered tax obligations arising from that vesting event, and the transaction is classified as a tax-withholding disposition exempt under Rule 16(b)-3, rather than a voluntary stock sale.

What does Rule 16(b)-3 exemption mean for this Cohu (COHU) insider transaction?

Rule 16(b)-3 exemption means the tax-withholding disposition is treated as a permitted, non-speculative transaction. The automatic withholding of 998 shares to pay taxes on RSU vesting is considered administrative and does not indicate discretionary trading in Cohu stock by the executive.
