March 6 (Reuters) - Prudential Financial's ( PRU )

Japanese life insurance subsidiary said on Friday that some

workers assigned to contracted agencies improperly removed

operational information and shared it with other employees.

The company reported that 11 employees took operational

information on 379 occasions at seven agencies and shared it

with other Prudential staff, who used the data to help plan

sales promotion strategies.

It said the information that was taken related to

operational matters, including sales performance at the

agencies.

The development comes after the CEO of Prudential's Japanese

life insurance unit resigned last month, following revelations

of misconduct by about 100 of its employees totaling about 3.1

billion yen.

"Both the seconded employees who removed the information and

the employees who received it lacked a fundamental understanding

of the rules and failed to perform basic compliance actions,"

Prudential Gibraltar Financial Life Insurance said in a

statement.

It will eliminate its life insurance secondments by the end

of March, the company said, adding that some former and current

executives will voluntarily return a portion of their

compensation.

"After confirming the content of all cases with the

agencies, no issues were identified that would raise concerns

under the Unfair Competition Prevention Act, nor was there any

inappropriate removal of contract information," it added.

Shares of the Prudential, the parent company, were down 3.4%

in morning trading.
