MADRID, Sept 30 (Reuters) - Spain's Banco Santander said on Friday it had trimmed its profitability targets for 2018 to just above 11 percent by 2018 in a business environment it described as "significantly worse" than last year.
At its investor day last year the euro zone's biggest bank by market value said it was aiming for a return on tangible equity ratio (ROTE) of around 13 percent by 2018.
The lender also weakened its cost to income ratio to a range of between 45 percent and 47 percent by 2018, against last year's objective of below 45 percent.
The bank's shares were down 3.8 percent against a 3 percent drop against the European banking index.
