•Medicare-Internal: The Medicare-Internal segment relates to sales of products and plans by GoHealth-employed agents offering qualified prospects plans from multiple carriers, GoHealth-employed agents offering qualified prospects plans on a carrier-specific basis, or sales of products and plans through our online platform without the assistance of our agents, which we refer to as DIY. In this segment, we sell Medicare Advantage, Medicare Supplement, Medicare prescription drug plans, and Medicare Special Needs Plans, or SNPs. We earn revenue in this segment through commissions paid by carriers based on sales we generated, as well as enrollment fees, hourly fees and other fees for services performed for specific carriers and other partners. The Medicare-Internal segment is our largest and fastest growing segment, and represented 96% of segment profits in 2020.
The following table sets forth the reconciliations of GAAP net income (loss) to EBITDA and Adjusted EBITDA for the periods presented:
Our agent base increased approximately 60% during the twelve months ended December 31, 2020 compared to the twelve months ended December 31, 2019.
Total Medicare Submitted Policies were 729,912 for the twelve months ended December 31, 2020, 268,882 for the Successor 2019 Period and 158,815 for the Predecessor 2019 Period. The increase is attributable to improved multichannel marketing strategies that allowed us to generate a greater number of high quality prospects, along with increased efficiency of our agents. Agent efficiency increased due to the implementation of more efficient marketing strategies and improvements in our LeadScore and call-routing technologies, which allowed our agents to increase the number of qualified prospects they are able to talk to and improve the rate at which a qualified prospect converts to a Submitted Policy. Additionally, the successful hiring, onboarding, and training of additional agents contributed to the increase in Submitted Policies. We were also able to drive an increase in total Submitted Policies in the Medicare-External segment due to our ability to recruit and onboard additional external agents to enroll consumers in Medicare plans using our technology and platform.
