2 3 T H E L A C L E D E G R O U P Net Economic Earnings (Non-GAAP) Reconciliation Amounts presented net of income taxes, which are calculated by applying federal, state, and local income tax rates applicable to ordinary income to the amounts of pre-tax reconciling items. Net economic earnings per share and net economic earnings per share excluding propane sale are calculated by replacing net income with net economic earnings and net economic earnings excluding propane sale in the GAAP diluted earnings per share calculation. Also, net economic earnings per share exclude the impact of the May 2013 equity offering to fund the acquisition of MGE. For the fiscal year ended September 30, 2013, the weighted average diluted shares used in the net economic earnings per share calculation was 22.5 million compared to 26.0 million in the GAAP EPS calculation. (1) For fiscal years 2013, 2011, 2010, and 2009, the amounts of income tax expense (benefit) included in the consolidated reconciling items above are $7.5 million, $0.9 million, $(1.3) million, and $2.2 million. Such amount is negligible for fiscal 2012. (2) Income tax expense associated with the sale of excess propane inventories was $3.9 million and $2.3 million for fiscal years 2011 and 2010, respectively.
