FRANKFURT--Deutsche Boerse AG (DB1.XE) plans a small capital increase to finance its previously the announced takeover of foreign-exchange trading platform 360T, Chief Executive Carsten Kengeter said in an article published by German Sunday newspaper Frankfurter Allgemeine Sonntagszeitung.

"We will finance the takeover by an optimal mix of equity and debt. The equity capital increase will be the much smaller part of the mix," Mr. Kengeter said, according to an advance summary of the article made available on Saturday.

A week ago, Deutsche Boerse said it would buy 360T for 725 million euros ($795.6 million). On Monday, it said it would buy two Swiss joint ventures for 650 million Swiss francs ($673 million).

In the newspaper article, Mr. Kengeter, who took the helm of the German exchange operator on June 1, reiterated plans to boost the company's profits in the coming years through a number of measures such as increasing growth and efficiency and cutting personnel costs. "We want to avoid compulsory layoffs," Mr. Kengeter said, adding that he has already started talks with labor representatives.
