Does value of the company increase when interest is double

Question

According to the valuation method depends on tax shields, the value of the company (Vl) is the value of the unleveraged company (Vu) in addition with the value of tax shields (VTS), thus, the higher the interest and the higher the VTS. Therefore, does the value of the company increase when I call my bank and tell them to charge me twice the interest?

Answer 1

In fact, the valuation formula is VL = Vu + VTS. There value of the company (VL) is also the value of the shares (E) in addition with the value of the debt (D). Therefore, E + D = Vu + VTS. The result of double interests would be: an increase in VTS that would be superior to D causing a decrease into E.

The value of the company does increase although the value of the debt increases and also the value of the shares decreases (this does not seem to satisfy shareholders unless they own the debt).
