WASHINGTON (AP) - Federal regulators say they're concerned about a continued heavy risk in large loans made by banks and other financial institutions, with the amount of risky loans remaining at double the levels before the financial crisis.

WASHINGTON (AP) Federal regulators say they're concerned about a continued heavy risk in large loans made by banks and other financial institutions, with the amount of risky loans remaining at double the levels before the financial crisis.

The Federal Reserve and other agencies say that a large portion of the risk comes from loans made to investment firms for financing takeovers of companies. Those loans, called leveraged loans, accounted for 22.6 percent of total large loans outstanding and 74.7 percent of the loans deemed risky by the regulators, according to the agencies' latest annual review.

The review found "serious deficiencies" in credit standards for making leveraged loans and in managing their risk.

Overall, the review found that $340.8 billion, or 10.1 percent, of big loans outstanding were deemed risky.
