Why paying off EMD Sorono ?

Contractual obligations remaining with EMD Serono totalled US$28.2 million.
Thera paid off with a renegotiated price totalled UDS$23.85 million
The saving is: US$28.2 million - UDS$23.85 million = USD$4,350,000
So, the yearly saving would be USD$1,087,500/yr
The real interest expense for the payoff would be 5.75% of USD$23.85 million, not the entire USD$50 million, since the balance after paying off Serono would be used for other things.
Actual interest expense is: $23.85 million x 5.75% = USD$1.371 million/yr
So, the actual cost to payoff early is: USD$1.371 million - USD$1.087 = $284,000 / yr
The increase in Egrifta sales would more than offset this cost.
