Financial Data of Business Segments

The financial data presented below depicts the profitability, financial position, and capital expenditures of each of our business segments.

We lease, operate, manage, and remarket long-lived, widely-used assets, primarily in the rail market. We report our financial results through four primary business segments: Rail North America, Rail International, American Steamship Company (“ASC”), and Portfolio Management.

Rail North America is composed of our operations in the United States, Canada, and Mexico, as well as an affiliate investment. Rail North America primarily provides railcars pursuant to full-service leases under which it maintains the railcars, pays ad valorem taxes and insurance, and provides other ancillary services.

Rail International is composed of our operations in Europe ("GATX Rail Europe" or "GRE"), India ("Rail India"), and Russia ("Rail Russia"). GRE leases railcars to customers throughout Europe pursuant to full-service leases under which it maintains the railcars and provides value-adding services according to customer requirements.

ASC operates the largest fleet of US-flagged vessels on the Great Lakes, providing waterborne transportation of dry bulk commodities such as iron ore, coal, limestone aggregates, and metallurgical limestone.

Portfolio Management is composed primarily of our ownership in a group of joint ventures with Rolls-Royce plc that lease aircraft spare engines, as well as five liquefied gas carrying vessels (the "Norgas Vessels") and assorted other marine assets. In prior years, Portfolio Management generated leasing, marine operating, asset remarketing, and management fee income through a collection of diversified wholly owned assets and joint venture investments. In 2015, we made the decision to exit the majority of the marine investments, excluding the Norgas Vessels, within our Portfolio Management segment, including six chemical parcel tankers, a number of inland marine vessels, and our 50% interest in the Cardinal Marine joint venture, all of which have been sold as of December 31, 2017.

Segment profit is an internal performance measure used by the Chief Executive Officer to assess the performance of each segment in a given period. Segment profit includes all revenues, pre-tax earnings from affiliates, and net gains on asset dispositions that are attributable to the segments, as well as expenses that management believes are directly associated with the financing, maintenance, and operation of the revenue earning assets. Segment profit excludes selling, general and administrative expenses, income taxes, and certain other amounts not allocated to the segments. These amounts are included in Other.

We allocate debt balances and related interest expense to each segment based upon predetermined debt to equity leverage ratios. Due to the changes in the composition of our segments, we modified segment leverage levels for 2016. The leverage levels for 2017 and 2016 were 5:1 for Rail North America, 3:1 for Rail International, 1.5:1 for ASC, and 1:1 for Portfolio Management. For 2015, the leverage levels were 5:1 for Rail North America, 2:1 for Rail International, 1.5:1 for ASC, and 3:1 for Portfolio Management. We believe that by using this leverage and interest expense allocation methodology, each operating segment’s financial performance reflects appropriate risk-adjusted borrowing costs.

The following tables show certain segment data for the years ended December 31, 2017, 2016, and 2015 (in millions):
