It is 2 weeks for every year of service, and doesn't include the 30 day notice period. Medical benefits are also included 2 weeks for every year of service, and STIs/LTIs are prorated and paid out as part of severance. Any unused vacation is also paid out.
It's a very generous deal, and I have an opportunity to take another position in the company but honestly I'm not sure I can afford to. Walking away with $120k+ in parting gifts is a pretty great deal.
