Congress is finishing work on a $1.1 trillion bill that finances operations of most federal agencies and includes dozens of policy riders and directives. Here are some highlights:

DODD-FRANK Relaxes restrictions on big banks’ trading of certain risky financial instruments known as swaps. Restrictions were imposed by the 2010 Dodd-Frank financial law.

CAMPAIGN FINANCE Greatly increases federal limits on individual contributions to national political parties and their congressional campaign committees.

PENSIONS Allows trustees of certain multiemployer pension plans to cut retirees’ benefits, keeping the plans solvent without a government bailout.

E.P.A. Cuts funds for the Environmental Protection Agency; prohibits the agency from regulating the lead content of ammunition or fishing tackle.
