[1] For the years ended April 30, 2018, 2017, and 2016, we allocated all of corporate overhead expenses except for interest and income taxes, such as general and administrative expenses and other corporate-level expenses, to both our Firearms and Outdoor Products & Accessories segments.

[2] Amounts include an income tax benefit of approximately $8.7 million, primarily caused by the effect of Tax Reform, which resulted in the remeasurement of deferred tax assets and liabilities at lower enacted corporate federal tax rates.

[3] Basic and diluted earnings per share may not equal the sum of the quarterly basic and diluted earnings per share due to rounding.
