More than half of distressed-debt investors believe the majority of debt restructurings in Europe are still on tap, according to a survey by Debtwire and the law firm Cadwalader, Wickersham & Taft. One-fifth of respondents expect restructurings to peak in the first six months of the year, while 35% point to the second half. Senior debt was chosen by 37% of participants as the instrument that will offer the most attractive investment opportunities. The U.K. and Spain are the countries seen as having the largest number of debt restructurings this year.
