THE AES CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) DECEMBER 31, 2011, 2010, AND 2009 20.
IMPAIRMENT EXPENSE Asset Impairment Asset impairment expense for the year ended December 31, 2011 consisted of:
## Table 0 ##
Wind Turbines & Deposits—During the third quarter of 2011, the Company evaluated the future use of certain wind turbines held in storage pending their installation.
Due to reduced wind turbine market pricing and advances in turbine technology, the Company determined it was more likely than not that the turbines would be sold significantly before the end of their previously estimated useful lives.
In addition, the Company has concluded that more likely than not non-refundable deposits it had made in prior years to a turbine manufacturer for the purchase of wind turbines are not recoverable.
The Company determined it was more likely than not that it would not proceed with the purchase of turbines due to the availability of more advanced and lower cost turbines in the market.
These developments were more likely than not as of September 30, 2011 and as a result were considered impairment indicators and the Company determined that an impairment had occurred as of September 30, 2011 as the aggregate carrying amount of $161 million of these assets was not recoverable and was reduced to their estimated fair value of $45 million determined under the market approach.
This resulted in asset impairment expense of $116 million.
Wind Generation is reported in the Corporate and Other segment.
In January 2012, the Company forfeited the deposits for which a full impairment charge was recognized in the third quarter of 2011, and there is no obligation for further payments under the related turbine supply agreement.
Additionally, the Company sold some of the turbines held in storage during the fourth quarter of 2011 and is continuing to evaluate the future use of the turbines held in storage.
The Company determined it is more likely than not that they will be sold, however they are not being actively marketed for sale at this time as the Company is reconsidering the potential use of the turbines in light of recent development activity at one of its advance stage development projects.
It is reasonably possible that the turbines could incur further loss in value due to changing market conditions and advances in technology.
Tisza II—During the fourth quarter of 2011, Tisza II, a 900 MW gas and oil-fired generation plant in Hungary entered into annual negotiations with its offtaker.
As a result of these negotiations, as well as the further deterioration of the economic environment in Hungary, the Company determined that an indicator of impairment existed at December 31, 2011.
Thus, the Company performed an asset impairment test and determined that based on the undiscounted cash flow analysis, the carrying amount of Tisza II asset group was not recoverable.
The fair value of the asset group was then determined using a discounted cash flow analysis.
The carrying value of the Tisza II asset group of $94 million exceeded the fair value of $42 million resulting in the recognition of asset impairment expense of $52 million during the three months ended December 31, 2011.
Tisza II is reported in the Europe Generation reportable segment.
Kelanitissa—In 2011, the Company recognized asset impairment expense of $42 million for the long-lived assets of Kelanitissa, our diesel-fired generation plant in Sri Lanka.
We have continued to evaluate the recoverability of our long-lived assets at Kelanitissa as a result of both the existing government regulation which

Net Investment Hedge During the second quarter of 2016, the Company designated certain intercompany debt as a non-derivative net investment hedging instrument against foreign currency exposure related to its net investment in foreign operations.
At December 31, 2017, ￡130 million ($175.9 million) of intercompany debt was designated as a net investment hedge.
For the twelve months ended December 31, 2017, the Company recognized foreign currency losses of $15.3 million resulting from the net investment hedge within currency translation differences on investments in foreign subsidiaries in other comprehensive income.
No hedge ineffectiveness was recognized in income.11.
SHARE-BASED COMPENSATION The company recognized total expenses of $175.3 million, $159.7 million and $150.3 million related to equity-settled share-based payment transactions in 2017, 2016 and 2015, respectively.
Thetotal income tax benefit recognized in the Consolidated Statemets n n of Income for share-based compensation arrangements was $48.9 million for 2017 (2016: $44.7 million; 2015: $43.8 million).
Share awards are broadly classified into two categories: time-vested and performance-vested.
Share awards are measured at fair value at the date of grant and are expensed, based on the company's estimate of shares that will eventually vest, on a straight-line or accelerated basis over the vesting period.
Time-vested awards vest ratably over or cliff- f f vest at the end of a period of continued employee service.
Performance-vested awards cliff- f f vest at the end of or vest ratably over a defined vesting period of continued employee service upon the company's attainment of certain performance criteria.
Time-vested and performance-vested share awards are granted in the form of restricted share awards (RSAs) or restricted share units (RSUs).
Performance-vested awards are tied to the achievement of specified levels of adjusted diluted earnings per share and adjusted operating margin.
In the event that either targeted financial measure is achieved at or above a vesting threshold for a particular performance measurement period, the portion of the performance-vested award subject to targeted financial measures will vest proportionately between 0% and 100% based upon the higher achieved level for that year.
With respect to time-vested awards, dividends accrue directly to the employee holder of RSAs, and cash payments in lieu of dividends are made to employee holders of certain RSUs.
With respect to performance-vested awards, dividends and cash payments in lieu of dividends are deferred and are paid at the same rate as on our shares if and to the extent the award vests.
Item 7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations Investments – (Continued) CNA may purchase other securities that, according to CNA’s analysis, are undervalued in relation to other securities in the market.
In making these value decisions, securities may be bought and sold that shift the investment portfolio between asset classes.
CNA also continually monitors exposure to issuers of securities held and broader industry sector exposures and may from time to time reduce such exposures based on its views of a specific issuer or industry sector.
These activities will produce realized gains or losses.
The investment portfolio is periodically analyzed for changes in duration and related price change risk.
In addition, CNA periodically reviews the sensitivity of the portfolio to the level of foreign exchange rates and other factors that contribute to market price changes.
A summary of these risks and specific analysis on changes is included in Item 7A – Quantitative and Qualitative Disclosures about Market Risk included herein.
Under certain economic conditions, including but not limited to a changing interest rate environment, CNA may hedge the value of the investment portfolio by utilizing derivative strategies, as discussed further in Notes 1 and 4 of the Notes to Consolidated Financial Statements.
CNA invests in certain derivative financial instruments primarily to reduce its exposure to market risk (principally interest rate, equity price and foreign currency risk) and credit risk (risk of nonperformance of underlying obligor).
Derivative securities are recorded at fair value at the reporting date.
CNA also uses derivatives to mitigate market risk by purchasing S&P 500 index futures in a notional amount equal to the contract liability relating to Life and Group NonCore indexed group annuity contracts.
CNA provided collateral to satisfy margin deposits on exchange-traded derivatives totaling $64.0 million as of December 31, 2005.
For over-the-counter derivative transactions CNA utilizes International Swaps and Derivatives Association (“ISDA”) Master Agreements that specify certain limits over which collateral is exchanged.
As of December 31, 2005, CNA provided $2.0 million of cash as collateral for over-the-counter derivative instruments.
A further consideration in the management of the investment portfolio is the characteristics of the underlying liabilities and the ability to align the duration of the portfolio to those liabilities to meet future liquidity needs, minimize interest rate risk and maintain a level of income sufficient to support the underlying insurance liabilities.
For portfolios where future liability cash flows are determinable and long term in nature, CNA segregates assets for asset liability management purposes.
CNA classifies its fixed maturity securities (bonds and redeemable preferred stocks) and its equity securities as either available-for-sale or trading, and as such, they are carried at fair value.
The amortized cost of fixed maturity securities is adjusted for amortization of premiums and accretion of discounts to maturity, which is included in net investment income.
Changes in fair value related to available-for-sale securities are reported as a component of other comprehensive income.
Changes in fair value of trading securities are reported within net investment income.
The following table provides further detail of gross realized gains and losses on available-for-sale fixed maturity and equity securities:
