Boston ? Investors continue to pull money out of Putnam Investments, with assets under management declining by $7 billion in the past week and $21 billion overall since the mutual funds scandals surfaced last month.

Putnam on Monday reported $256 billion in assets under management as of Friday. A week earlier, it had $263 billion under management. At the end of October, the company had $277 billion under management.

A Putnam spokeswoman did not immediately return a call seeking comment on the fund levels, which were reported in a filing by Marsh & McLennan Cos., Putnam’s parent company, with the Securities and Exchange Commission.

The company has said it was committed to swiftly and thoroughly addressing issues and rebuilding its reputation for integrity and reliability.

Putnam has been embroiled in controversy since state and federal regulators announced civil fraud charges against it for failing to crack down on market timing trades by employees.

“Market timing” refers to the use of quick, in-and-out trades that skim profits from longer-term shareholders. The practice is not illegal but most funds do not allow it.
