We annually perform premium deficiency testing in the aggregate across our run-off insurance portfolio in the third quarter. As a result of the testing, we identified no premium deficiency. See the Other Items section and Note 12 for further information. GE Capital received $2 billion of additional capital contributions from GE in the fourth quarter of 2020. See the Capital Resources and Liquidity section for further information. As previously mentioned, GE reached a settlement with the SEC and paid a civil penalty of $0.2 billion in December 2020, of which $0.1 billion was recorded and paid at GE Capital. See Note 23 for further information.

(b) Included cash, cash equivalents and restricted cash of $13,245 million as of December 31, 2020 and $17,618 million as of December 31, 2019. (a) Capital segment revenues represent 9% of total segment revenues for the year ended December 31, 2020. (b) Other continuing operations primarily comprised excess interest costs from debt previously allocated to assets that have been sold as part of the GE Capital Exit Plan, preferred stock dividend costs and interest costs not allocated to GE Capital businesses, which are driven by GE Capital’s interest allocation process. Interest costs are allocated to GE Capital businesses based on the tenor of their assets using the market rate at the time of origination, which differs from the asset profile when the debt was originated. As a result, actual interest expense is higher than interest expense allocated to the remaining GE Capital businesses. All preferred stock dividend costs have become a GE Industrial obligation in January 2021. See Note 16 for further information. In addition, we anticipate unallocated interest costs to gradually decline as debt matures and/or is refinanced. For the year ended December 31, 2020, segment revenues decreased $1.5 billion (17%) and segment losses were up $1.2 billion. Capital revenues decreased $1.5 billion (17%), as a result of volume declines and lower gains. These volume declines were primarily at GECAS related to lower interest income attributable to the sale of PK AirFinance and lower rental revenue on our aircraft leasing portfolio, and at WCS related to lower purchases of GE Industrial customer receivables and the run-off of the GE Capital supply chain finance program (See GE Industrial Working Capital Transactions for further information). Capital losses increased $1.2 billion, primarily due to an impairment of goodwill of $0.8 billion (pre-tax), volume declines, higher mark-to-market effects and other impairments, including $0.5 billion (pre-tax) on the GECAS fixed-wing aircraft portfolio as a result of COVID-19 and related market impacts, lower gains, debt tender costs, the SEC settlement charge and the nonrecurrence of a 2019 tax reform enactment adjustment. These increased losses were partially offset by the nonrecurrence of a $1.0 billion pre-tax charge identified through the completion of our 2019 annual insurance premium deficiency review, higher tax benefits including the tax benefit related to the BioPharma sale and lower excess interest cost. Gains were $0.4 billion and $0.7 billion in 2020 and 2019, respectively, which primarily related to sales of certain GECAS aircraft and engines resulting in gains of $0.2 billion and $0.4 billion in 2020 and 2019, respectively, and the sale of equity method investments resulting in gains of $0.1 billion and $0.2 billion in 2020 and 2019, respectively, at EFS.
