The company, which will announce its Solvency II position alongside its preliminary results on 15 March, has recently seen its share price drop dramatically, plummeting more than 10 per cent in last week's trading.
In a note published this morning, researchers at Panmure Gordon & Co called the announcement a surprise and said they felt the move was one designed to "reassure and calm investor nerves".
"We welcome the clarity, which should reassure, but are surprised that L&G felt the need to respond to analyst calls in this way so close to the prelim announcement," the note added.
