Basic Management, a private fund controlled by a member of the Radziwill family, sold off its entire stake in GasLog Partners, according to a filing with the US Securities and Exchange Commission.

John Albert Stanislas Radziwill, who is the uncle of GasLog chairman Peter Livanos and the father of GasLog board director Philip Radziwill, sold just under 2.4 million units in the LNG carrier partnership in a brokered transaction at the end of last week, the filing said. The sale was motivated by "general portfolio management decisions," according to the filing.

Radziwill's fund netted an average price of just over $19 per unit through the sale. The fund bought into GasLog Partners in May 2014 just after its initial public offering at $21 per unit.
