FAIR VALUE MEASUREMENTS The Company determines the fair market values of its financial instruments based on the fair value hierarchy established in SFAS No.157, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
The standard describes three levels of inputs that may be used to measure fair value.
Level 1 Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
The Company’s Level 1 assets consist of available-for-sale securities traded on active markets as well as certain Brazilian Treasury securities that are highly liquid and are actively traded in over-the-counter markets.
Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

TELEFLEX INCORPORATED NOTES?TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) F-37 Note 13?— Income taxes The following table summarizes the components of the provision for income taxes from continuing operations:
## Table 1 ##
The Tax Cuts and Jobs Act (the “TCJA”) was enacted on December 22, 2017.
The legislation significantly changes U. S.  tax law by, among other things, permanently reducing corporate income tax rates from a maximum of 35% to 21%, effective January 1, 2018; implementing a territorial tax system, by generally providing for, among other things, a dividends received deduction on the foreign source portion of dividends received from a foreign corporation if specified conditions are met; and imposing a one-time repatriation tax on undistributed post-1986 foreign subsidiary earnings and profits, which are deemed repatriated for purposes of the tax.
As a result of the TCJA, the Company reassessed and revalued its ending net deferred tax liabilities at December 31, 2017 and recognized a?$46.1 million?provisional tax benefit in the Company’s consolidated statement of income for the year ended December 31, 2017.
As a result of the deemed repatriation tax under the TCJA, the Company recognized a $154.0 million provisional tax expense in the Company’s consolidated statement of income for the year ended December 31, 2017, and the Company expects to pay this tax over an eight-year period.
While the TCJA provides for a territorial tax system, beginning in 2018, it includes?two?new U. S.  tax base erosion provisions, the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) provisions.
The GILTI provisions require the Company to include in its U. S.  income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets.
The Company expects that it will be subject to incremental U. S.  tax on GILTI income beginning in 2018.
Because of the complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the TCJA and the application of Financial Accounting Standards Board Accounting Standards Codification Topic 740, "Income Taxes. "
Under U. S.  GAAP, the Company may make an accounting policy election to either (1) treat future taxes with respect to the inclusion in U. S.  taxable income of amounts related to GILTI as current period expense when incurred (the “period cost method”) or (2) take such amounts into a company’s measurement of its deferred taxes (the “deferred method”).
The Company’s selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on an analysis of the Company’s global income to determine whether the Company expects to have future U. S.  inclusions in taxable income related to GILTI and, if so, what the impact is expected to be.
The determination of whether the Company expects to have future U. S.  inclusions

Miller Insurance Services LLP, which is a Pounds sterling functional entity, earns significant non-functional currency revenues, in which case the Company limits its exposure to exchange rate changes by the use of forward contracts matched to a percentage of forecast cash inflows in specific currencies and periods.
However, where the foreign exchange risk relates to any Pounds sterling pension benefits assets or liability for pension benefits, we do not hedge the risk.
Consequently, if our London market operations have a significant pension asset or liability, we may be exposed to accounting gains and losses, recognized in other comprehensive income or loss, if the U. S.  dollar and Pounds sterling exchange rates change.
We do, however, hedge the Pounds sterling contributions into the pension plan.
Translation risk Outside our U. S.  and London market operations, we predominantly earn revenues and incur expenses in the local currency.
When we translate the results and net assets of these operations into U. S.  dollars for reporting purposes, movements in exchange rates will affect reported results and net assets.
For example, if the U. S.  dollar strengthens against the Euro, the reported results of our Eurozone operations in U. S.  dollar terms will be lower.
With the exception of foreign currency hedges for certain intercompany loans that are not designated as hedging instruments, we do not hedge translation risk.
The table below provides information about our foreign currency forward exchange contracts, which are sensitive to exchange rate risk.
The table summarizes the U. S.  dollar equivalent amounts of each currency bought and sold forward and the weighted average contractual exchange rates.
All forward exchange contracts mature within three years.
## Table 2 ##
(i) Represents the difference between the contract amount and the cash flow in U. S.  dollars which would have been receivable had the foreign currency forward exchange contracts been entered into on December 31, 2016 at the forward exchange rates prevailing at that date.
