The Institute for the Works of Religion, commonly referred to as the Vatican bank, made a profit of 36 million euros (about £32 million/$40 million) in 2016, according to its annual report.

The Institute held assets worth 5.7 billion euros at year's end, which included deposits and investments from close to 15,000 clients -- mostly Catholic religious orders around the world, Vatican offices and employees, and Catholic clergy.

Before the report's release, the 2016 financial statements were audited by the firm Deloitte & Touche and were reviewed by the Commission of Cardinals overseeing the institute's work.
