The world's biggest investor has warned companies it will fight oversized pay packets and undeserved pensions in the coming year, marking the latest challenge to how British boardrooms set pay.
Blackrock has written to the chairmen of London-listed businesses about its plan to vote against any big pay rises that are "out of line with the rest of the workforce" or the company's performance without a good reason.
"Executive pay should be strongly linked to performance, by which we mean strong and sustainable returns over the long-term, as opposed to short-term hikes in share prices," wrote Amra Balic, head of investment stewardship at Blackrock.
The company also drew attention to cash payments handed to directors instead of pension contributions, which can run into hundreds of thousands of pounds at a time when many businesses are cutting retirement schemes for employees.
"We expect pension contributions for executives to be in line with the rest of the workforce for new contracts," it said.
