Is Berkshire a Bigger Investment Company?

Berkshire's finance and financial products segment had a fairly significant increase in the amount of cash carried on the group's books last year. The amount of cash held at the segment spiked up to $5.4 billion at the end of the third quarter of last year and $7.1 billion by the end of 2015. This incidentally coincided with your acquisition of G's, rail car leasing unit, as well as the acquisition of several rail car repair and maintenance facilities.
