Next, grade company does grade (especially dominion credence grade) , a certain country, a certain organization does not give its right, because do not have any countries or organization,have this right. They do grade, it is act of a kind of trade above all, just be approbated because of grade result by more orgnaization, brought public letter force thereby.
For example mark general of the United States, held water 1860, be by the earliest standard publication company and company of general Er statistic are incorporated and come, 100 will be engaged in analysis of financial data statistic and grade service all the time for years, mark general is approbated on the market, because approbate its,be the justice of hundred years old store, objective.
