Singer's unsecured redeemable debentures were rated A+ (lka) by Fitch Ratings Lanka last May.
Pieris did not specify, but analysts expect most of the funds to go towards retiring some short-term debt and feed their hire-purchase loan book.
For the first quarter ended March 31, 2006 Singer's hire purchase portfolio stood at around 5.0 billion rupees. The portfolio has an annual growth of between 25-30 percent.
Nearly half of the firm's sales now come from hire purchase schemes. Defaults are low, around 2-percent.
