Optimum Communications (OPTU) shares jumped 81% in Monday trading after the company reported a series of transactions involving a newly formed unrestricted subsidiary, CSC Investments II, designed to raise and allocate about $500 million in capital.

The unit raised $300 million through a private placement of preferred units to third-party institutional investors. It also exchanged $200 million of preferred units for Optimum common stock held by controlling stockholder Next Alt at $2.50 apiece.

Optimum said the newly created subsidiary will hold the Optimum East Cable business and its 50.01% stake in Lightpath, as part of an internal reorganization aimed at making the assets financially and operationally independent from its parent, CSC Holdings.

Separately, CSC Investments II launched a cash tender offer for up to 120 million shares of Optimum class A common stock, or up to $300 million in value, at $2.50 per share. The company said the offer is not subject to a minimum condition or financing condition and will expire on June 30.

The unit said it expects to fund the tender offer with proceeds from the private placement and existing cash.
