US-based cable operator Liberty Global Inc (LGI) yesterday announced the authorisation of a new USD1 billion stock repurchase programme. Under the plan LGI says it may acquire from time to time its Series A common stock, Series C common stock, or any combination of Series A and Series C common stock. The stock repurchase programme may be effected through open market transactions and/or privately negotiated transactions, which may include derivative transactions. The cable services operator added a caveat that the timing of the repurchase programme is dependent on a number of factors, such as market conditions, and could be suspended or discontinued at any time. As of 30 September 2011, LGI operated cable networks serving 18 million customers across 14 countries principally located in Europe, Chile and Australia.
