AOL is buying content personalization start-up Gravity for about $90 million in cash.
The purchase will include $12 million of net operating losses, which will result in a cash tax benefit to AOL of about $5 million.
AOL will use Gravity's technology across various devices and its properties, including the Huffington Post.

"AOL is going to be a supercustomer of Gravity," AOL CEO Tim Armstrong said. "But this is about extending those capabilities even further as personal becomes the most important signal for publishers and advertisers."
Gravity will continue to operate from its main headquarters in Santa Monica, Calif.
The deal is expected to close in the first quarter.
