Income Taxes	Note 11. INCOME TAXES As a limited partnership, we are not subject to federal and state income taxes, however our corporate subsidiaries are subject to income taxes. Income tax attributable to our taxable income, which may differ significantly from income for financial statement purposes, is assessed at the individual limited partner unit holder level. We are subject to a statutory requirement that non-qualifying income, as defined by the Internal Revenue Code, cannot exceed 10% of total gross income for the calendar year. If non-qualifying income exceeds this statutory limit, we would be taxed as a corporation. The non-qualifying income did not exceed the statutory limit in any period presented. Certain activities that generate non-qualifying income are conducted through LGWS. LGWS is a tax paying corporate subsidiary of ours that is subject to federal and state income taxes. Current and deferred income taxes are recognized on the earnings of LGWS. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are measured using enacted tax rates. We recorded an income tax benefit of $2.7 million and an insignificant amount for the three months ended June 30, 2018 and 2017, and an income tax benefit of $2.4 million and $2.7 million for the six months ended June 30, 2018 and 2017, respectively, as a result of the income generated (or losses incurred) by our corporate subsidiaries. The effective tax rate differs from the combined federal and state statutory rate primarily because only LGWS is subject to income tax.

Note 11. INCOME TAXES

As a limited partnership, we are not subject to federal and state income taxes, however our corporate subsidiaries are subject to income taxes. Income tax attributable to our taxable income, which may differ significantly from income for financial statement purposes, is assessed at the individual limited partner unit holder level. We are subject to a statutory requirement that non-qualifying income, as defined by the Internal Revenue Code, cannot exceed 10% of total gross income for the calendar year. If non-qualifying income exceeds this statutory limit, we would be taxed as a corporation. The non-qualifying income did not exceed the statutory limit in any period presented.

Certain activities that generate non-qualifying income are conducted through LGWS. LGWS is a tax paying corporate subsidiary of ours that is subject to federal and state income taxes. Current and deferred income taxes are recognized on the earnings of LGWS. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are measured using enacted tax rates.

We recorded an income tax benefit of $2.7 million and an insignificant amount for the three months ended June 30, 2018 and 2017, and an income tax benefit of $2.4 million and $2.7 million for the six months ended June 30, 2018 and 2017, respectively, as a result of the income generated (or losses incurred) by our corporate subsidiaries. The effective tax rate differs from the combined federal and state statutory rate primarily because only LGWS is subject to income tax.
