According to the CBI, Sukh Ram has invested over Rs 20 crore with certain individuals and companies to earn interest on a regular basis. The diaries seized from his residences are said to contain details of the illegal transactions. Entries in one of the diaries, the CBI officials interrogating him say, show that Sukh Ram has invested money in foreign currency, which brings him under the purview of the Foreign Exchange Regulation Act (FERA). Most of these entries are in Sukh Ram’s own hand. But, for reasons best known to the CBI, he has not yet been booked under FERA. The coded entries show that Sukh Ram gave $400,000 to one "C.K." in four instalments of $100,000 each. The entry reads: "Rs 35 L to C.K... 1$". The investigators have deciphered "35 L" as Rs 35 lakh and "1$" as $100,000.
