CSR has provided a copy of its share register to Share Buying Group Pty Ltd, following a request by that company.

Under the Corporations Act CSR was obliged to comply with this request.

But CSR has warned shareholders to beware of any unsolicited offer they may receive.

It says that if a shareholder accepts an unsolicited offer, it may result in them receiving a price for their shares below what they could receive by trading on the market through a licensed broker.

Alternatively, shareholders may receive an offer at market price but with unfavourable terms - for example, payment staggered over an extended time frame.

CSR is recommending that if shareholders receive an unsolicited offer for their shares they should read the documentation carefully and seek independent financial advice before making any decisions.
