The Benefits of Increasing Berkshire's Float

Buffett's 2015 annual letter he said that the large amount of float that Berkshire possesses allows the company to significantly increase its investment income. What happens when interest rates decline if the US were to implement negative interest rates in the same way that the Eurozone and Japan have done how would Berkshire be affected? Well some of our float actually exists in Europe where we have the problem of negative interest rates on on very high grade short term and medium even medium term bonds. Anything that reduces the value of having money is going to affect Berkshire because we're always going to have a lot of money.
