Global ERP implementation charges. Global ERP implementation charges consist of the non-capitalizable portion of internal labor and outside consulting costs related to the implementation of a global ERP system. We have inherited many diverse business processes and different information systems through our numerous acquisitions. Accordingly, we are undertaking this initiative in order to standardize business processes globally and to better integrate all of our existing and acquired operations using one information system. Although recurring in nature given the expected timeframe to complete the implementation for our existing operations and our expectation to continue to acquire new businesses and operations, management excludes these charges when evaluating the operating performance of the Company because the frequency and amount of such charges vary significantly based on the timing and magnitude of the Company's implementation activities.

•

Structural optimization charges. These charges, which include employee severance and other costs associated with exit or disposal of facilities, costs related to transferring manufacturing and/or distribution activities to different locations, and rationalization or enhancement of our organization, existing manufacturing, distribution, administrative, functional and commercial infrastructure. Some of these cost-saving and efficiency-driven activities are identified as opportunities in connection with acquisitions that provide the Company with additional capacity or economies of scale. Although recurring in nature given management's ongoing review of the efficiency of our organization and structure, including manufacturing, distribution and administrative facilities and operations, management excludes these items when evaluating the operating performance of the Company because the frequency and amount of such charges vary significantly based on the timing and magnitude of the Company's rationalization activities and are, in some cases, dependent upon opportunities identified in acquisitions, which also vary in frequency and magnitude.

•

Certain employee severance charges. Certain employee severance and related charges consist of charges related to senior management level terminations and certain significant reductions in force that are not initiated in connection with restructuring. Management excludes these items when evaluating the Company's operating performance because these amounts do not affect our core operations and because of the infrequent and/or large scale nature of these activities.

•

Acquisition-related charges. Acquisition-related charges include (i) up-front fees and milestone payments that are expensed as incurred in connection with acquiring licenses or rights to technology for which no product has been approved for sale by regulatory authorities and such approval is not reasonably assured at the time such up-front fees or milestone payments are made, (ii) inventory fair value purchase accounting adjustments, (iii) changes in the fair value of contingent consideration after the acquisition date, (iv) costs related to acquisition integration including systems, operations, retention, and severance and (v) legal, accounting and other outside consultants expenses directly related to acquisitions or divestitures. Inventory fair value purchase accounting adjustments consist of the increase to cost of goods sold that occur as a result of expensing the “step up” in the fair value of inventory that we purchased in connection with acquisitions as that inventory is sold during the financial period. Although recurring given the ongoing character of our development and acquisition programs, these acquisition, divestiture and in-licensing related charges are not factored into the evaluation of our performance by management after completion of development programs or acquisitions because they are of a temporary nature, they are not related to our core operating performance and the frequency and amount of such charges vary significantly based on the timing and magnitude of our development, acquisition and divestiture transactions as well as the level of inventory on hand at the time of acquisition.

•	Discontinued product lines charges. These charges represent charges taken in connection with product lines that the Company discontinues. Management excludes this item when evaluating the Company’s operating performance because discontinued products do not provide useful information regarding the Company’s prospects for future performance.

•	Intangible asset amortization expense. Management excludes this item when evaluating the Company's operating performance because it is a non-cash expense.

•

Convertible debt non-cash interest. The convertible debt accounting requires separate accounting for the liability and equity components of the Company's convertible debt instruments, which may be settled in cash upon conversion, in a manner that reflects an applicable non-convertible debt borrowing rate at the time that we issued such convertible debt instruments. Management excludes this item when evaluating the Company's operating performance because of the non-cash nature of the expense.

•	Income tax impact from adjustments and other items. Estimated impact on income tax expense related to the following:

(i)	Adjustments to income tax expense for the amount of additional tax expense that the Company estimates that it would record if it used non-GAAP results instead of GAAP results in the calculation of its tax provision, based on the statutory rate applicable to jurisdictions in which the above non-GAAP adjustments relate.

(ii)

When we calculate the adjusted tax rate, we include a full year estimate for all discrete items. We then apply that full year rate to the year-to-date results and calculate the current quarter’s rate to arrive at the year-to-date adjusted tax rate. We believe this removes significant variability in our results and creates a more operationally consistent result for our investors to use for comparability purposes. Specifically, the adoption of the FASB Update No. 2016-09 accounting standard has the effect of generating a significant tax expense benefit in each of the first three quarters of 2016. For the adjusted tax rate, we are treating this as a rate item, which is consistent with how other discrete tax expense items are handled in our current adjusted tax expense measure.

•	The Company periodically acquires other companies or businesses, and we expect to continue to incur acquisition-related expenses and charges in the future. These costs can directly impact the amount of the Company's available funds or could include costs for aborted deals which may be significant and reduce GAAP net income.

•	The Company has initiated a long term effort to implement a global ERP system, and we expect to continue to incur significant systems implementation charges until that effort is completed. These costs can directly impact the amount of the Company's available funds and reduce GAAP net income.

•	All of the adjustments to GAAP net income have been tax affected at the Company's actual tax rates. Depending on the nature of the adjustments and the tax treatment of the underlying items, the effective tax rate related to adjusted net income could differ significantly from the effective tax rate related to GAAP net income.
