Table of Contents Newfoundland, independent distributors in Newfoundland and government liquor commissioners in Yukon, Northwest territories, and Nunavut. Our products can be purchased by consumers at the government's Liquor Distribution Branch retail outlet, at any independently owned and licensed retail store or at any licensed establishment for on-premise consumption in British Columbia and, in Alberta, at retail outlets licensed by the Alberta Gaming and Liquor Commission or licensees such as bars, hotels and restaurants. In the Caribbean, Latin and South America, we use a combination of export models and license agreements to sell  Blue Moon, Coors Light, Miller Genuine Draft, Miller High Life, Miller Lite  and other brands. In our export model markets, we import beer from the U.S. and sell it through agreements with independent distributors. In license markets, we have established exclusive licensing agreements with brewers and distributors for the manufacturing and distribution of our products. In certain of our markets, we rely on a combination of these agreements. References to on- and off-premise sales volumes are sales to retailers, which we believe is a useful data point relative to consumer trends. In North America, the on-premise channel includes sales to bars and restaurants while the off-premise channel includes sales in convenience stores, grocery stores, liquor stores and other retail outlets including The Beer Store in Ontario, Canada which is Canada's largest beer retailer and is co-owned by Ontario's three largest brewers. The following table reflects the industry channel share trends over the last five years in the largest regions in our North America segment of Canada and the U.S. Percentages reflect estimates based on market data currently available. Channels We continue to monitor the coronavirus pandemic, which has had a material adverse effect on our North America operations, liquidity, financial condition and results of operations in the second quarter of 2020 due to on-premise closures. The pandemic continued to have a significant adverse effect during the third and fourth quarters of 2020 due to the on-premise locations only being open at partial capacity and at reduced hours. We currently expect these significant adverse effects to continue into 2021 as on-premise locations have experienced, and we believe will continue to experience, capacity and hour limitations. The effects of the pandemic remain highly uncertain especially around the duration of the outbreak and actions by government authorities to contain the pandemic or address its impact, among other things. We estimate that approximately 9% and 9% of 2020 North America volume and net sales, respectively, were from the on-premise channel. This compares to our 2019 estimate that approximately 16% and 17% of our volume and net sales, respectively, were from the on-premise channel which tends to be more profitable than the off-premise channel as a result of its higher above premium brand mix, higher net sales revenue per hectoliter and lower package costs due to the higher volume of kegs sold. We have seen some of the on-premise demand shift to the off-premise; however, this shift has not been proportionate to the severe declines in volume lost from the on-premise closures and weakened demand. As a result of the coronavirus pandemic and resulting government-imposed restrictions and related on-premise closures, this portion of our business effectively ceased entirely from the middle of March 2020 into June 2020. Additionally, continuing governmental or societal impositions on bars and restaurants and restrictions on public gatherings including the growing risk of a return of shutdowns, especially if prolonged in nature, we expect will continue to have adverse effects on on-premise traffic and, in turn, our business performance, cash flows and liquidity. See Part II. Item 7. Management's Discussion and Analysis,  "Executive Summary"  & Results of Operations— "North America,"  for further details. Manufacturing, Production and Packaging We use high quality ingredients to brew our products. Hops used in our North American products are purchased from suppliers in the U.S. and Europe. These contracts vary in length based on market conditions and cover our supply requirements through 2021. We malt a portion of our production requirements in North America, using barley purchased primarily under annual contracts from independent farmers located predominately in the western United States and Canadian Prairies. In addition, we source barley malt from three other commercial providers, from which we have a committed supply until at least 2022.
