While there is still some fringe debate what companies will do with the hundreds of billions in offshore funds repatriated to the US as part of the recently passed Trump tax reform, the discussion is largely over, especially after last week’s Cisco results. The company, which has $68 billion of overseas cash, third after AAPL and MSFT, announced that it would raise its buyback authorization by $25 billion, and revealed plans to repurchase its entire authorization of $31 billion during the next 6-8 quarters, equal to roughly 15% of its current market cap.
