US-listed asset manager Janus Capital managed to more than double its net income to $130m (€106m) in the second quarter to June, against the same period last year, thanks to a one-off $228m profit from the sale of 9% of DST Systems, the software developer.

The DST profit helped offset a debt restructuring costing $55m; severance payments of $21.6m, and the $6m charge incurred by the firm as a result of the regulatory probe into its mutual funds following the market timing scandal.
