Google bought Motorola for 12.5 billion and then sold off it's Home division for 2.3 billion. At the time of the purchase, Motorola had 2 billion in cash so in the end, Google probably paid 8 billion ish for Motorola. Considering that in those 1.5 years, Moto and Nokia's values have been decreasing as well, I think they are pretty close in value.
