The U.S. Senate approved a bill Thursday to extend the terrorism risk insurance act until the end of 2020, MarketWatch reported. The bill, which was passed by the House Wednesday, now goes to President Barack Obama for his signature. The insurance program, which was first enacted in 2002, expired at the end of 2014. The bill includes a provision changing part of the Dodd-Frank financial law, by prohibiting regulators from imposing margin requirements on non-financial users of derivatives. Sen. Elizabeth Warren, a Massachusetts Democrat, authored an amendment to halt the change, but it was defeated. The bill passed on a vote of 93 to 4.
