Amortization expense for definite life intangible assets was $1.1 million, $1.0 million and $1.0 million for years 2017, 2016 and 2015, respectively.

Indefinite life intangible assets are composed of trade names and trademarks that have an indefinite life and are therefore individually tested for impairment on an annual basis, or more frequently in certain circumstances where impairment indicators arise, in accordance with FASB ASC 350. Our measurement date for impairment testing is October 1st of each year. When performing our test for impairment of individual indefinite life intangible assets, we use a relief from royalty method to determine the fair market value that is compared to the carrying value of the indefinite life intangible asset. The inputs used for this analysis are considered Level 3 inputs in the fair value hierarchy. See note 14 for further discussion of the fair value hierarchy. Our October 1st review for 2017 and 2016 did not indicate impairment of our indefinite life intangible assets.

The remaining definite life intangible assets at December 31, 2017 consist of customer relationships that are amortized over a period ranging from 13 to 20 years. The weighted average remaining life on the definite life intangible assets is 2.4 years at December 31, 2017.

Future estimated amortization expense of definite life intangible assets is as follows (dollars in thousands):

Goodwill impairment tests are completed for each reporting unit on an annual basis, or more frequently in certain circumstances where impairment indicators arise. The inputs used for this analysis are considered Level 2 and Level 3 inputs in the fair value hierarchy. See note 14 for further discussion of the fair value hierarchy.

As part of our on-going assessment of goodwill at September 30, 2017, we noted that third quarter 2017 sales, profitability and cash flow of our Mexico reporting unit (within the Latin America segment) significantly underperformed in comparison to the forecast, and expectations for the fourth quarter of 2017 were lowered as well. These factors, as well as continuing competitive pressures, long term weakness of the Mexican peso relative to the U.S. dollar, and an increase in the discount rate of 70 basis points from December 31, 2016 to September 30, 2017, all contributed to increased pressure on the outlook of the reporting unit. As a result, we determined a triggering event had occurred for our Mexico reporting unit. Accordingly, an interim impairment test was performed as of September 30, 2017, indicating that the carrying value of the Mexico reporting unit exceeded its fair value, and in accordance with the early adoption of ASU 2017-04, we recorded a non-cash impairment charge of $79.7 million during the third quarter of 2017.

When performing our test for impairment, we measure each reporting unit's fair value using a combination of "income" and "market" approaches on a shipping point basis. The income approach calculates the fair value of the reporting unit based on a discounted cash flow analysis, incorporating the weighted average cost of capital of a hypothetical third-party buyer. Significant estimates in the income approach include the following: discount rate; expected financial outlook and profitability of the reporting unit's business; and foreign currency impacts (Level 3 inputs). Discount rates use the weighted average cost of capital for companies within our peer group, adjusted for specific company risk premium factors. The market approach uses the "Guideline Company" method, which calculates the fair value of the reporting unit based on a comparison of the reporting unit to comparable publicly traded companies. Significant estimates in the market approach model include identifying similar companies with comparable business factors such as size, growth, profitability, risk and return on investment, assessing comparable multiples, as well as consideration of control premiums (Level 2 inputs). The blended approach assigns a 70 percent weighting to the income approach and 30 percent to the market approach (Level 3 input). The higher weighting is given to the income approach due to some limitations of publicly available peer information used in the market approach. The blended fair value of both approaches is then compared to the carrying value, and to the extent that fair value exceeds the carrying value, no impairment exists. However, to the extent the carrying value exceeds the fair value, an impairment is recorded.

Our annual review was performed as of October 1st for each year presented. As the impairment assessment performed at September 30, 2017 resulted in the fair value of the Mexico reporting unit equaling its carrying value, there was no further impairment as of October 1, 2017. In addition, there were no indicators of impairment at December 31, 2017. Our review for 2016 did not indicate an impairment of goodwill.
