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.
