The numbers still do not work

The apparent budget shortfall is $100,000,000 to $300,000,000.

450 people have left. At an average of $130,000 cost per person (most are not expensive technical staff members), this amounts to $58,000,000 in apparent savings leaving $41,500,000 to $241,500,000 unaccounted for. Following Director Anastasio's comments that the 39 weeks of severance pay is the same as a person's salary from now until the end of the fiscal year (and ignoring complications of trying to follow where all the overhead costs really go), it is not clear whether there is any savings in expenditures at all.

Can someone explain the apparent smoke and mirrors to me?
