LONDON (Bloomberg) — UK insurer Standard Life Plc said third-quarter sales rose 41 percent, driven by pensions in its home market. The shares fell after the company said it will review provisions for pension-policy cancellations.New business rose to $375 million ($715 million), from $266 million in the year-earlier period, the Edinburgh-based insurer said in a statement.

Pension customers who remained to get shares in Standard Life’s $1 billion initial public offering in July are leaving at a faster rate, causing the company to increase provisions for lapsed pensions by $100 million in September.

The lapses “continue above the long-term trend,” Trevor Matthews, chief executive officer of UK and European life and pensions, said.

UK nine-month sales rose 35 percent to $921 million, surpassing the analyst estimate of $902 million.
