Google ended up having to toss another $140 million into the mix to fully conclude its DoubleClick purchase. The company disclosed a final price of $3.24 billion in an SEC filing.

"The “Calculation Amount” under the Merger Agreement was approximately $3.24 billion, consisting of $3.11 billion plus the cash and cash equivalents of DoubleClick and its subsidiaries plus the aggregate exercise price for outstanding options and stock appreciation rights for DoubleClick common stock minus unpaid third party expenses incurred by DoubleClick in connection with the Merger and minus all indebtedness for borrowed money of DoubleClick," Google said in its Form 8-K.

Google began pursuing DoubleClick in 2007, and secured FTC approval in December. In Europe, however, competition regulators asked for more time to look over the proposal.

Although the decision-making process in Brussels could have taken until April, investigators had concluded the deal would merge complementary businesses and gave its approval in March.

"We are thrilled that our acquisition of DoubleClick has closed," Google CEO Eric Schmidt said in response to news of Europe giving the merger the OK. Google now has the leading display ad platform on the Internet to go along with its dominant paid search business.
