[1] Alternative minimum tax credit carryforwards can be utilized to offset payment of federal income taxes on future taxable income, if any, earned by this subsidiary, subject to certain limitations.

[2] Excludes $3.5 million in remaining net operating loss carryforwards which expire beginning after 2019. Should these carryforwards be utilized, they will be excluded for purposes of calculating the Company's provision for income taxes. Any such utilization will, however, reduce actual taxes payable.

[3] Because this subsidiary is not expected to earn significant amounts of taxable income, related net deferred tax assets are fully reserved at December 31, 2015.
