simplest math

Today basekt-price: 62 US$/kg
Costs per kg: 8 US$/kg
normal PER: 10
actually MC: ca. 2 Billion US$
============================================
a) If the price holds 62US$/kg
b) If the price go down 50% (to 31US$/kg)
c) If the price doubles (to 124 US$/kg)
============================================
2011:
-----
half year 11.000t REO-production = 5.500t
a)5.500 * 62.000-8.000 = 297 Mio. US$/YEAR!
b)5.500 * 31.000-8.000 = 127 Mio. US$/YEAR!
c)5.500 * 124.000-8.000 = 638 Mio. US$/YEAR!

2012:
-----
full year 11.000t REO REO-production - this means double of the numbers in 2011:
a) 297 Mio. * 2 = 594 Mio. US$/YEAR!
b) 127 Mio. * 2 = 254 Mio US$/YEAR!
c) 638 Mio. * 2 = 1.276 Mio. US$/YEAR!

2013:
-----
full year 22.000t REO-production - this means double of the numbers in 2012:

a) 594 Mio. * 2 = 1.188 Mio. US$/YEAR!
b) 254 Mio. * 2 = 508 Mio US$/YEAR!
c) 1.276 Mio. * 2 = 2.552 Mio. US$/YEAR!

This means for PER:
===================
2011:
-----
a) a PER of 7
b) a PER of 16
c) a PER of 3

2012:
-----
a) a PER of 3
b) a PER of 8
c) a PER of 2

2012:
-----
a) a PER of 2
b) a PER of 4
c) a PER of 1

My personal goal for 2012: 14 AUD
