According to Twitter (link here), Paul Westphal came onto 1140 today and said that the Brock Ness Monster has been given a Qualifying Offer, officially making him a Restricted Free Agent. This means that the Kings can match any offers from other teams, or retain him for that amount ($937,195). It's not a surprising move, Nessie is a great guy to have around the locker room and an extremely hard worker. I'll update this with the "official" link when its announced.
UPDATE (H/T to pookeyguru): Voisin confirms in a Live Chat. Here's the transcript.
