Will NTA will decline for NSC, more than other NAOS LIC’s

Hi All

NAOS has reported they have sold some of its holdings in BRI - Big River Industries, see announcement here:

As you can see NSC holds the majority of BRI. NSC holds 20,099,774 shares of BRI, current value $27,235,193.

Believe this will reduce NSC’s NTA as NAOS sells off this holding. BRI could go below $1 with this type of liquidation sale by NAOS. This would imply a further reduction of 5c in NTA at each announcement for NSC, or $7M of 134,973,497 in NSC shares on issue (BRI reduction of $0.355 is $7M loss to NSC).

What are others thoughts, is this an opportunity to monitor as an opportunity to buy in the coming months/years or a terminal issue for an investment manager that doesn’t deserve their 1.25% management fee?

Best of Luck
