Unusual or Infrequent Item, or Both, Nature of Event or Transaction	ContingenciesLease GuaranteesAs a result of having assigned our interest in obligations under real estate leases as a condition to the refranchising of certain Company-owned restaurants, and guaranteeing certain other leases, we are frequently secondarily liable on lease agreements. These leases have varying terms, the latest of which expires in 2065. As of December 31, 2020, the potential amount of undiscounted payments we could be required to make in the event of non-payment by the primary lessee was approximately $425 million. The present value of these potential payments discounted at our pre-tax cost of debt at December 31, 2020, was approximately $375 million. Our franchisees are the primary lessees under the vast majority of these leases. We generally have cross-default provisions with these franchisees that would put them in default of their franchise agreement in the event of non-payment under the lease. We believe these cross-default provisions significantly reduce the risk that we will be required to make payments under these leases. Accordingly, the liability recorded for our expected exposure under such leases at December 31, 2020, and December 31, 2019, was not material.Insurance ProgramsWe are self-insured for a substantial portion of our current and prior years’ coverage including property and casualty losses. To mitigate the cost of our exposures for certain property and casualty losses, we self-insure the risks of loss up to defined maximum per occurrence retentions on a line-by-line basis. The Company then purchases insurance coverage, up to a certain limit, for losses that exceed the self-insurance per occurrence retention. The insurers’ maximum aggregate loss limits are significantly above our actuarially determined probable losses; therefore, we believe the likelihood of losses exceeding the insurers’ maximum aggregate loss limits is remote.The following table summarizes the 2020 and 2019 activity related to our net self-insured property and casualty reserves as of December 31, 2020.

See Note 3.Due to the inherent volatility of actuarially determined property and casualty loss estimates, it is reasonably possible that we could experience changes in estimated losses which could be material to our growth in quarterly and annual Net Income. We believe that we have recorded reserves for property and casualty losses at a level which has substantially mitigated the potential negative impact of adverse developments and/or volatility.In the U.S. and in certain other countries, we are also self-insured for healthcare claims and long-term disability for eligible participating employees subject to certain deductibles and limitations. We have accounted for our retained liabilities for property and casualty losses, healthcare and long-term disability claims, including reported and incurred but not reported claims, based on information provided by independent actuaries.Legal Proceedings We are subject to various claims and contingencies related to lawsuits, real estate, environmental and other matters arising in the normal course of business. An accrual is recorded with respect to claims or contingencies for which a loss is determined to be probable and reasonably estimable.Yum! Restaurants India Private Limited (“YRIPL”), a YUM subsidiary that operates KFC and Pizza Hut restaurants in India, is the subject of a regulatory enforcement action in India (the “Action”). The Action alleges, among other things, that KFC International Holdings, Inc. and Pizza Hut International failed to satisfy certain conditions imposed by the Secretariat for Industrial Approval in 1993 and 1994 when those companies were granted permission for foreign investment and operation in India. The conditions at issue include an alleged minimum investment commitment and store build requirements as well as limitations on the remittance of fees outside of India.The Action originated with a complaint and show cause notice filed in 2009 against YRIPL by the Deputy Director of the Directorate of Enforcement (“DOE”) of the Indian Ministry of Finance following an income tax audit for the years 2002 and 2003. The matter was argued at various hearings in 2015, but no order was issued. Following a change in the incumbent official holding the position of Special Director of DOE (the “Special Director”), the matter resumed in 2018 and several additional hearings were conducted. On January 29, 2020, the Special Director issued an order imposing a penalty on YRIPL and certain former directors of approximately Indian Rupee 11 billion, or approximately $150 million. Of this amount, $145 million relates to the alleged failure to invest a total of $80 million in India within an initial seven-year period. We have been advised by external counsel that the order is flawed and have filed a writ petition with the Delhi High Court, which granted an interim stay of the penalty order on March 5, 2020. The stay order remains in effect, and the next hearing is scheduled for March 24, 2021. We deny liability and intend to continue vigorously defending this matter. We do not consider the risk of any significant loss arising from this order to be probable.We are currently engaged in various other legal proceedings and have certain unresolved claims pending, the ultimate liability for which, if any, cannot be determined at this time. However, based upon consultation with legal counsel, we are of the opinion that such proceedings and claims are not expected to have a material adverse effect, individually or in the aggregate, on our Consolidated Financial Statements.
