Apple's plan to take out a loan for its $60 billion stock buyback is about saving taxes, notes the Washington Post. Although the company has $145 billion in cash reserves, roughly two-thirds of that is situated outside the US, and Apple has so far avoided repatriating the money in order to bypass a 35 percent tax rate. Taking out a loan for $60 billion means the company must still pay interest, but this is offset by not having to pay out dividends on the shares it's reclaiming.
