MADRID, Dec 1 (Reuters) - Spain's Santander SAN.MC plans to sell an around 3.5% stake in its Polish subsidiary Santander Polska SPL1.WA through an accelerated bookbuild for around $480 million, one of the bookrunners said on Monday.
This would leave Santander with an around 9.7% stake in its Polish unit.
The partial divestment follows an agreement to sell a 49% stake in Santander's Polish bank for around 6.8 billion euros announced earlier in May.
A bookrunner of the placement said that Santander would sell around 3.6 million shares in Santander Polska for a range of between 481 to 486 zlotys per share.
This would represent a discount of between 5% to 6% compared to Monday's closing price of 511.6 zlotys per share.
Santander declined to comment on the price.
