Reorganizations of motor carriers shall be subject to the supervision and control of the division of motor carrier and railroad safety and no such reorganization shall be had without the authorization of the division. Upon all such reorganizations the amount of capitalization, including therein all stocks and bonds and other evidence of indebtedness, shall be such as is authorized by the division which, in making its determination, shall not exceed the fair value of the property involved, taking into consideration its original cost of construction, duplication costs, present condition, earning power at reasonable rates and all other relevant matters and any additional sum or sums as shall be actually paid in cash; provided, however, that the division may make due allowance for discount of bonds. Any reorganization agreement before it becomes effective shall be amended so that the amount of capitalization shall conform to the amount authorized by the division. The division may by its order impose such condition or conditions as it may deem reasonable and necessary.
