(1)	At September 27, 2019, accumulated impairment losses for the Transportation Solutions, Industrial Solutions, and Communications Solutions segments were $2,191 million, $669 million, and $489 million, respectively.

(2)	At March 27, 2020, accumulated impairment losses for the Transportation Solutions, Industrial Solutions, and Communications Solutions segments were $3,091 million, $669 million, and $489 million, respectively.

In March 2020, we completed the acquisition of First Sensor and recognized goodwill in the Transportation Solutions segment. Due to the timing of the transaction, we have preliminarily allocated the purchase price of First Sensor to

goodwill. We are in the process of completing the valuation of identifiable intangible assets, assets acquired, and liabilities assumed; therefore, the current allocation is subject to adjustment upon finalization of those valuations. The amount of these potential adjustments could be significant. In addition, during the six months ended March 27, 2020, we recognized goodwill in the Transportation Solutions and Industrial Solutions segments in connection with other recent acquisitions. See Note 4 for additional information regarding acquisitions.

We test goodwill allocated to reporting units for impairment annually during the fiscal fourth quarter, or more frequently if events occur or circumstances exist that indicate that a reporting unit’s carrying value may exceed its fair value. As a result of current and projected declines in sales and profitability, due in part to the impact of the coronavirus disease COVID-19 and projected reductions in global automotive production, of the Sensors reporting unit of the Transportation Solutions segment during the quarter ended March 27, 2020, we determined that an indicator of impairment had occurred and goodwill impairment testing of this reporting unit was required.

As discussed in Note 1, during the quarter ended March 27, 2020, we adopted ASU No. 2017-04 which simplifies the subsequent measurement of goodwill by eliminating step 2 of the goodwill impairment test. Under the new standard, goodwill impairment is measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying value of goodwill. We determined the fair value of the Sensors reporting unit to be $1.0 billion. This valuation was based on a discounted cash flows analysis incorporating our estimate of future operating performance, which we consider to be a level 3 unobservable input in the fair value hierarchy, and was corroborated using a market approach valuation. The goodwill impairment test indicated that the carrying value of the reporting unit exceeded its fair value by $900 million. As a result, we recorded a partial impairment charge of $900 million. The Sensors reporting unit had a remaining goodwill allocation of $626 million as of March 27, 2020.

Should economic conditions deteriorate further or remain depressed for a prolonged period of time, estimates of future cash flows for each of our reporting units may be insufficient to support the carrying value and the goodwill assigned to it, requiring impairment charges, including additional impairment charges for the Sensors reporting unit. Further impairment charges, if any, may be material to our results of operations and financial position.
