PITTSBURGH (KDKA) — The Pittsburgh Steelers are the 15th most valuable team in the NFL, according to Forbes’ annual study.

The business magazine published its 21st annual NFL team valuations list Thursday.

Forbes calculates each NFL team’s value based on multiples of revenue of historical transactions, offers to buy and invest in teams currently on the table, each team’s current stadium, and revenue and operating income for the 2017 season. Forbes also took revenue from non-NFL events that can be pocketed by the team owner or an entity the owner controls into consideration.

According to the study, the Steelers are worth $2.585 billion with a revenue of $415 million and an operating income of $85 million. Forbes says the average NFL team is worth $2.57 billion.
