Walter O’Connor reported an administrative reallocation of 578.620 phantom shares on February 23, 2026. The units, valued at $10.77 each, were converted using the fund reorganization exchange ratio and moved from BlackRock MuniYield Fund, Inc. to BlackRock MuniYield Quality Fund, Inc.

What are phantom shares in the context of BlackRock MuniYield Fund, Inc. (MYD)?

Phantom shares are compensation units economically equivalent to one common share, but settled in cash. For MYD, these phantom shares track the value of the fund’s common stock and, once vesting requirements are met, become payable in cash rather than delivering actual fund shares.

Did Walter O’Connor buy or sell MYD common shares in this Form 4 filing?

The Form 4 does not show a traditional buy or sell of MYD common shares. It records an “other” transaction code J, reflecting reallocation and conversion of phantom share units due to a fund reorganization, rather than an open-market trade or new grant.

How many MYD-related phantom shares were affected in the February 2026 transaction?

The transaction involved 578.620 MYD-related phantom shares. These units, economically equivalent to common shares, were converted using the reorganization exchange ratio and reallocated to BlackRock MuniYield Quality Fund, Inc., leaving zero phantom shares reported for the original fund afterward.

What was the reference value per MYD phantom share in Walter O’Connor’s Form 4?

Each phantom share was valued at $10.77 in the reported transaction. This price represents the per-unit economic reference used in the compensation record when 578.620 phantom shares were reallocated during the fund’s reorganization into BlackRock MuniYield Quality Fund, Inc.

Why did MYD reallocate Walter O’Connor’s phantom shares to BlackRock MuniYield Quality Fund, Inc.?

The reallocation occurred because BlackRock MuniYield Fund, Inc. was reorganized into BlackRock MuniYield Quality Fund, Inc. on February 23, 2026. Phantom stock units previously awarded in the original fund were shifted and converted at the same exchange ratio used for the broader reorganization.
