[1] The in-process technology was not subject to amortization at the acquisition date. A portion of the acquired in-process technology valued at $0.3 million was written off in 2012 subsequent to the acquisition as the related project was abandoned. Amortization was commenced for the balance of the in-process technology in 2013 upon completion of the related project.

[2] For the first quarter of 2013, the retrospective application of the accounting change for pension and other postretirement benefit plan asset and actuarial gains and losses increased gross profit by $1.8 million, operating income by $8.3 million, net earnings by $5.2 million, basic EPS by $0.08, and diluted EPS by $0.09. For the second quarter of 2013, the retrospective application of the accounting change for pension and other postretirement benefit plan asset and actuarial gains and losses increased gross profit by $1.7 million, operating income by $8.3 million, net earnings by $5.2 million, basic EPS by $0.08, and diluted EPS by $0.08. For the third quarter of 2013, the retrospective application of the accounting change for pension and other postretirement benefit plan asset and actuarial gains and losses increased gross profit by $1.7 million, operating income by $8.3 million, net earnings by $5.2 million, basic EPS by $0.09, and diluted EPS by $0.08. For the fourth quarter of 2013, the retrospective application of the accounting change for pension and other postretirement benefit plan asset and actuarial gains and losses increased gross profit by $19.2 million, operating income by $90.9 million, net earnings by $55.7 million, basic EPS by $0.89, and diluted EPS by $0.88. Net earnings for the first quarter of 2013 included $9.1 million of pre-tax restructuring charges and project costs in connection with the Company's restructuring plans and $15.7 million of pre-tax charges in connection with intangible amortization and integration costs associated with the Company's acquisitions. Net earnings for the second quarter of 2013 included a $73.5 million pre-tax Gain on sale of inkjet-related technology and assets, $13.3 million of pre-tax restructuring charges and project costs in connection with the Company's restructuring plans, and $16.2 million of pre-tax charges in connection with intangible amortization and integration costs associated with the Company's acquisitions. Net earnings for the third quarter of 2013 included $17.7 million of pre-tax restructuring charges and project costs in connection with the Company's restructuring plans and $19.1 million of pre-tax charges in connection with intangible amortization and integration costs associated with the Company's acquisitions.

[3] The sum of the quarterly earnings per share amounts does not necessarily equal the annual earnings per share due to changes in average share calculations. This is in accordance with prescribed reporting requirements.

[4] The in-process technology was not subject to amoritzation at the acquisition date, but began amortizing upon completion of the projects in 2012.

[5] The estimated useful life of the trade names was shortened to approximately 2.5 years subsequent to the acquisition, resulting in accelerated amortization of the asset.

[6] Amortization to begin upon completion of the project.

[7] Deferred tax liability, net primarily relates to purchased identifiable intangible assets and is shown net of deferred tax assets.
