Scorpio Tankers retired one piece of its debt structure this week, redeeming a six-year-old so-called baby bond issue at maturity for $53.75m.

The unsecured notes, so-named because they are issued in $25 denominations, had carried an interest coupon of 6.75% at issue in May 2014.

Scorpio president Robert Bugbee revealed the redemption of the notes during a webinar with Arctic Securities analysts on Tuesday.
