According to the Russian Ministry of Finance, the foreign debt securities the fund can invest in must have ratings of AA- or higher by Fitch or Standard & Poor's, or a rating of Aa3 by Moody's.[1] Despite this, the fund agreed to buy (on 17 December 2013) $15 billion of Ukrainian Eurobonds, despite the fact that Ukraine had lower credit ratings at the time.[2][3][4]
