Equity in earnings of unconsolidated affiliates increased by $3.3 million during 2013. The increase is primarily attributable to lower interest expense from the refinancing of in December 2012 and increases in base rents and tenant reimbursements due to occupancy improvements and growth in rental rates at several unconsolidated affiliates. These increases were partially offset by a decrease of $2.6 million as a result of the IV Property being consolidated in the 2013 period. The income tax provision of $1.3 million in 2013 relates to the Management Company, which is a taxable REIT subsidiary, and consists of a current benefit of $0.5 million and a deferred income tax provision of $1.8 million. The income tax provision of $1.4 million in 2012 consists of a current tax benefit of $1.7 million and a deferred income tax provision of $3.1 million. The operating loss from discontinued operations for 2013 includes a $5.2 million loss on impairment of real estate to write down the net book value of a portfolio of six Properties sold during the period to the net sales price, a $2.9 million write-off of straight-line rent for Properties sold during the period, the operating results of three malls, three associated centers and five office buildings sold in 2013, and settlement of estimated expenses based on actual amounts for Properties sold during previous periods. The operating loss from discontinued operations for 2012 of $12.5 million includes a loss of $26.5 million on impairment of real estate related to two malls and one community center that were sold in 2012, which was partially offset by the operating results of two malls and four community centers that were sold during 2012 and the operating results of three malls, three associated centers and five office buildings that were sold in 2013, as well as settlement of estimated expenses based on actual amounts for Properties sold during previous periods. The $1.1 million gain on discontinued operations for 2013 represents the gain from the sale of five office buildings sold during the period as well as recognition of a gain from the sale of two office buildings, which had been deferred in 2008 until subsequent repayment of the related notes receivable. The gain on discontinued operations of $1.0 million in 2012 related to the sale of a community center.

Same-center Net Operating Income NOI is a supplemental measure of the operating performance of our shopping centers and other Properties. We define NOI as property operating revenues (rental revenues, tenant reimbursements and other income) less property operating expenses (property operating, real estate taxes and maintenance and repairs). Similar to FFO, we compute NOI based on our pro rata share of both consolidated and unconsolidated Properties. Our definition of NOI may be different than that used by other companies and, accordingly, our calculation of NOI may not be comparable to that of other companies. Since NOI includes only those revenues and expenses related to the operations of our shopping center Properties, we believe that same-center NOI provides a measure that reflects trends in occupancy rates, rental rates and operating costs and the impact of those trends on our results of operations. Our calculation of same-center NOI excludes lease termination income, straight-line rent adjustments, and amortization of above and below market lease intangibles in order to enhance the comparability of results from one period to another, as these items can be impacted by one-time events that may distort same-center NOI trends and may result in same-center NOI that is not indicative of the ongoing operations of our shopping center and other Properties. Same-center NOI is for real estate properties and does not include the results of operations of our subsidiary that provides janitorial, security and maintenance services. We include a Property in our same-center pool when we have owned all or a portion of the Property since January 1 of the preceding calendar year and it has been in operation for both the entire preceding calendar year ended December 31, 2013 and the current year ended December 31, 2014. New Properties are excluded from same-center NOI, until they meet this criteria. The only Properties excluded from the same-center pool that would otherwise meet this criteria are Non-core Properties, Properties under major redevelopment, Properties being considered for repositioning, Properties where we intend to renegotiate the terms of the debt secured by the related Property and Properties included in discontinued operations. Madison Square and Madison Plaza were classified as Non-core Properties as of December 31, 2014. Lender Properties consisted of , and Triangle Town Place as of December 31, 2014. Properties under major redevelopment as of December 31, 2014 included the Annex at Monroeville, CoolSprings Galleria and Northgate Mall. Properties where we are considering alternatives to reposition the Property included Chesterfield Mall and at December 31, 2014.
