[1] Results of operations for the tronc businesses are reflected through August 4, 2014, the date of the Publishing Spin-off.

[2] In connection with the Publishing Spin-off, the Company received a $275 million cash dividend from tronc utilizing borrowings of $350 million under a senior secured credit facility entered into by tronc prior to the Publishing Spin-off. The full amount of the $275 million cash dividend was used to repay $275 million of outstanding borrowings under the Company’s Term Loan Facility (as defined and described in Note 9). Interest expense associated with the Company’s outstanding debt was allocated to discontinued operations based on the ratio of the $275 million cash dividend received from tronc to the total outstanding indebtedness under the outstanding credit facilities in effect in each respective period prior to the Publishing Spin-off and totaled $7 million for the year ended December 28, 2014.

[3] The effective tax rate on pretax income from discontinued operations was 58.6% for the year ended December 28, 2014. This rate differs from the U.S. federal statutory rate of 35% primarily due to state income taxes (net of federal benefit) and the impact of certain nondeductible transaction costs.
