NEW YORK (AP) — Investors searching for income-generating investments are finding opportunities in the oil and gas pipelines that crisscross the country.

Many of the pipelines, holding tanks and other equipment that help get fuel to consumers are owned by firms called Master Limited Partnerships. They typically generate high income and tax benefits for investors because the firms are required by law to “pass through” much of their income and deductions to shareholders. In return, the partnerships pay no corporate tax.
