The average age of interims is rising, according to new data from Impact Executives, part of the Harvey Nash group.

The data shows that the proportion of interims over the age of 55 has risen in the past year, while 3% of respondents were over 65.

The data also shows that while last year the number of interims on assignment was fewer than those not on assignment, this year the balance has shifted again, with 55% working and 45% not.

Christine de Largy, managing director of Impact Executives, says:  “These results do not set out to shock or buck the trend but reiterate our continued message that things are heading in a positive direction, just at a slow, steady pace. We have also noted that in interim appointments, maturity and expertise will be important differentiators in cost reduction or profit improvement.”
