on either a straight-line or accelerated basis.
Amortization expense for intangibles was approximately $4.2 million, $4.1 million and $4.1 million during the years ended December 31, 2010, 2009 and 2008, respectively.
Estimated annual amortization expense of the December 31, 2010 balance for the years ended December 31, 2011 through 2015 is approximately $4.8 million.
Impairment of Long-Lived Assets Long-lived assets are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable.
If such review indicates that the carrying amount of longlived assets is not recoverable, the carrying amount of such assets is reduced to fair value.
During the year ended December 31, 2010, we recognized impairment charges on certain long-lived assets during the normal course of business of $1.3 million.
There were no adjustments to the carrying value of long-lived assets of continuing operations during the years ended December 31, 2009 or 2008.
Fair Value of Financial Instruments Our debt is reflected on the balance sheet at cost.
Based on market conditions as of December 31, 2010, the fair value of our term loans (see Note 5, “Long-Term Obligations”) reasonably approximated the carrying value of $590 million.
At December 31, 2009, the fair value of our term loans at $570 million was below the carrying value of $596 million because our interest rate margins were below the rate available in the market.
We estimated the fair value of our term loans by calculating the upfront cash payment a market participant would require to assume our obligations.
The upfront cash payment, excluding any issuance costs, is the amount that a market participant would be able to lend at December 31, 2010 and 2009 to an entity with a credit rating similar to ours and achieve sufficient cash inflows to cover the scheduled cash outflows under our term loans.
The carrying amounts of our cash and equivalents, net trade receivables and accounts payable approximate fair value.
We apply the market and income approaches to value our financial assets and liabilities, which include the cash surrender value of life insurance, deferred compensation liabilities and interest rate swaps.
Required fair value disclosures are included in Note 7, “Fair Value Measurements.
” Product Warranties Some of our salvage mechanical products are sold with a standard six-month warranty against defects.
Additionally, some of our remanufactured engines are sold with a standard three-year warranty against defects.
We record the estimated warranty costs at the time of sale using historical warranty claim information to project future warranty claims activity and related expenses.
The changes in the warranty reserve are as follows (in thousands):

Self-Insurance Reserves We self-insure a portion of employee medical benefits under the terms of our employee health insurance program.
We purchase certain stop-loss insurance to limit our liability exposure.
We also self-insure a portion of
RESTRICTED STOCK AWARDS During 2010, Regions granted 1 million restricted shares that vest based upon a service condition.
Dividend payments during the vesting period are deferred to the end of the vesting term.
The fair value of these restricted shares was estimated based upon the fair value of the underlying shares on the date of the grant.
The valuation was not adjusted for the deferral of dividends.
During 2009, Regions granted 3 million restricted shares that vest based upon a service condition and a market condition in addition to awards that were similar to prior grants.
The fair value of these restricted shares was estimated on the date of the grant using a Monte-Carlo simulation method.
The assumptions related to this grant included expected volatility of 84.81 percent, expected dividend yield of 1.00 percent, and an expected term of 4.0 years based on the vesting term of the market condition.
The risk-free rate is consistent with the assumption used to value stock options.
For all other grants that vest solely upon a service condition, the fair value of the awards is estimated based upon the fair value of the underlying shares on the date of the grant.
Restricted stock award and unit activity for 2010, 2009 and 2008 is summarized as follows: Number of
## Table 1 ##
As of December 31, 2010, the pre-tax amount of non-vested stock options and restricted stock awards and units not yet recognized was $51 million, which will be recognized over a weighted-average period of 0.90 years.
No share-based compensation costs were capitalized during the years ended December 31, 2010, 2009 and 2008.
Regions issued 857,957 and 645,683 of cash-settled restricted stock units during 2010 and 2009, respectively.
There were no cash-settled restricted stock units issued during 2008.
NOTE 17.
EMPLOYEE BENEFIT PLANS PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS Regions has a defined-benefit pension plan (the “pension plan”) covering only certain employees as the pension plan is closed to new entrants.
Benefits under the pension plan are based on years of service and the employee’s highest five years of compensation during the last ten years of employment.
Regions’ funding policy is to contribute annually at least the amount required by Internal Revenue Service minimum funding standards.
Contributions are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future.
The Company also sponsors a supplemental executive retirement program (the “SERP”), which is a non-qualified plan that provides certain senior executive officers defined benefits in relation to their compensation.
All defined-benefit plans are referred to as “the plans” throughout the remainder of this footnote.
Regions also sponsors defined-benefit postretirement health care plans that cover certain retired
