Thread regarding General Motors layoffs

I have some questions about the severance package and how it will be paid. I understand that everyone would get paid the next two pay checks (Feb 15th and Feb 28th). But how will they pay the severance amount? Say for example, you have worked for 4 years + and so you are supposed to get 2 months worth of pay. Are they going to pay you as they do now - 2 Paychecks in March and then 2 paychecks in April? Or are they going to pay you a lump sum amount with your last paycheck (on Feb 28th, as that's what many corporations do during layoff).
