[163-5] Moody’s and S&P’s Ratings / 迪與標準普爾的評級, 2011

Moody's Investor Service as well as Standard and Poor's, rate not only corporations but countries as well. Most institutional investment firms have rules prohibiting them from buying government bonds issued by countries with a low rating. Only blue-chip (Aaa=light color) and high to medium grade countries (Aa-Baa3=dark) are considered investment grades, all other countries (Ba1 to C) do not even show up on the investors' radar.

穆迪投資者服務公司與標準普爾公司不僅評估企業,也對國家進行評等。大多數的投資機構都有立定相關規定禁止購買評級較低的國家所發行的政府債券。只有藍籌股(AAA等級=淺藍色)以及高與中等級的國家(Aa-Baa3等級=深色)被視為投資等級,其他國家(Ba1到C等級)都不在投資者的考慮範圍內。
