FRANKFURT, Germany (AP) — Deutsche Bank co-CEO John Cryan is reassuring employees and the markets that Germany's largest lender remains "rock-solid" even though its shares have taken a beating.

The bank's shares have suffered in the days since it reported a 6.8 billion euro ($7.5 billion) loss for last year. Losses reported by competitor Credit Suisse and problems in Italy's financial system have helped feed concerns about banking stocks.

Cryan wrote in a message on the bank's website Tuesday that if clients ask about how market gyrations are affecting the bank, "you can tell them that Deutsche Bank remains absolutely rock-solid, given our strong capital and risk position."

The bank's shares were down 5 percent in afternoon trading in Europe and have fallen 23 percent since its earnings announcement Jan. 28.
