As far as I know, what you say doesn't seem correct.
On October 19, 2011, we had:
Shares Outstanding: 180,954,893
Cert Outstanding: 179,693,340
Book Outstanding: 1,261,553
On November 15, 2011, we had (your information):
Shares Outstanding: 180,954,893
The last time I posted the number of oustanding shares I only took the "cert" oustanding shares into account and I'll post again about it to correct this.
