CNBC's Jim Cramer said Monday the key to Google's recent success rests with new CFO Ruth Porat.
Cramer said last week's conference call run by Porat was more down to earth than previous ones.

At no point did it deviate into some sort of existential Kant versus Marx. ... There was no mention of Tolstoy. It frankly was about the numbers."
Google shares surged Friday after the company reported quarterly earnings that handily beat Wall Street expectations. Porat was named as Google's CFO on March 24.
