Kaupthing Bank HF, one of three failed Icelandic banks currently under government control, missed a scheduled coupon payment on a samurai bond sold in Japan, investors said.

Two holders of the notes said they hadn't received a transfer of funds due Monday for the Reykjavik-based bank's 1.8 percent securities. They declined to be identified or let their companies be named because of the sensitivity of the matter.

The bonds have semiannual interest payments of ¥450 million scheduled for October and April and are scheduled to mature next year.

Samurai bonds are debt sold in Japan by foreign borrowers.
