We test goodwill for impairment at the reporting unit level annually and more often if an event occurs or circumstances change that indicate the fair value of a reporting unit may be below its carrying amount. When applying the quantitative assessment, we determine the fair value of our reporting units based on a weighted average of multiple valuation techniques, principally a combination of an income approach and a market approach. The income approach calculates a value based upon the present value of estimated future cash flows, while the market approach uses earnings multiples of similarly situated guideline public companies. Determining the fair value of a reporting unit involves judgment and the use of significant estimates and assumptions, which include assumptions regarding the revenue growth rates and operating margins used to calculate estimated future cash flows, risk-adjusted discount rates and future economic and market conditions.  
The sustained decline in our share price and increases in discount rates, primarily resulting from increased economic uncertainty, indicated a potential decline in fair value and triggered a requirement to evaluate our Issuer Solutions and former Business and Consumer Solutions reporting units for potential impairment as of June 30, 2022. Further, the estimated sales price for the consumer business also indicated a potential decline in fair value of our former Business and Consumer Solutions reporting unit as of June 30, 2022. We determined on the basis of the quantitative assessment that the fair value of the Issuer Solutions reporting unit was still greater than its carrying amount as of June 30, 2022, indicating no impairment. Based on the quantitative assessment of our former Business and Consumer Solutions reporting unit, including consideration of the consumer business disposal group and the remaining assets of the reporting unit, we recognized a goodwill impairment charge of $833.1 million in our consolidated statement of income during the three months ended June 30, 2022. In connection with the change in presentation of segment information during the third quarter of 2022 as further described in “Note 14-Segment Information,” accumulated impairment losses associated with our former Business and Consumer Solutions reporting unit were reallocated to our new reporting units based on relative fair value.  
We continue to closely monitor developments related to COVID-19 and other global events and macroeconomic conditions. The future magnitude, duration and effects of these events and conditions are difficult to predict at this time, and it is reasonably possible that future developments could have a negative effect on the estimates and assumptions utilized in our goodwill impairment assessments and could result in material impairment charges in future periods.  
Accumulated impairment losses for goodwill as of September 30, 2022 were $833.1 million. There were no accumulated impairment losses for goodwill as of December 31, 2021.  
NOTE 6—OTHER ASSETS  
Visa Preferred Shares  
Through certain of our subsidiaries in Europe, we were a member and shareholder of Visa Europe Limited ("Visa Europe"). On June 21, 2016, Visa Inc. ("Visa") acquired all of the membership interests in Visa Europe, and we received consideration in the form of cash and Series B and C convertible preferred shares of Visa. We assigned the preferred shares received a value of zero based on transfer restrictions, Visa's ability to adjust the conversion rate and the estimation uncertainty associated with those factors. Based on the outcome of any current or potential litigation involving Visa Europe in the United Kingdom and elsewhere in Europe, the conversion rate of the preferred shares could be adjusted down such that the number of Visa common shares we receive could be as low as zero.  
The Series B and C convertible preferred shares become convertible in stages based on developments in the litigation and become fully convertible no later than 2028 (subject to a holdback to cover any then pending claims). In July 2022, in connection with the second mandatory release assessment, a portion of the Series B and C convertible preferred shares was converted by Visa representing approximately one quarter of the original potential conversion rate. We recognized a gain of $13.2 million reported in interest and other income in our consolidated statement of income for the three and nine months ended September 30, 2022 based on the fair value of the shares received. The shares were subsequently sold in September 2022. The remaining Series B and C convertible preferred shares continue to be carried at an assigned value of zero based on the aforementioned factors.
