CY2019	us-gaap	Use Of Estimates UseOfEstimates	To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements, income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including:<table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:24px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:9pt;padding-left:0px;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">•</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;font-size:9pt;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">allowance for credit losses (Note 6 (Loans and Allowance for Credit Losses)); </span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:24px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:9pt;padding-left:0px;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">•</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;font-size:9pt;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">valuations of residential mortgage servicing rights (MSRs) (Note 10 (Securitizations and Variable Interest Entities) and Note 11 (Mortgage Banking Activities)); </span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:24px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:9pt;padding-left:0px;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">•</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;font-size:9pt;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">valuations of financial instruments (Note 18 (Derivatives) and Note 19 (Fair Values of Assets and Liabilities));</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:24px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:9pt;padding-left:0px;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">•</span></div></td><td style="vertical-align:top;padding-left:24px;"><div style="line-height:120%;font-size:9pt;text-indent:-24px;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">liabilities for contingent litigation losses (Note 17 (Legal Actions)); and</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:24px;"/><td/></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:9pt;padding-left:0px;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">•</span></div></td><td style="vertical-align:top;padding-left:24px;"><div style="line-height:120%;font-size:9pt;text-indent:-24px;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">income taxes (Note 24 (Income Taxes)).</span></div></td></tr></table><div style="line-height:120%;font-size:9pt;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;"><br/></span></div><div style="line-height:120%;font-size:9pt;"><span style="font-family:Wells Fargo Sans,sans-serif;font-size:9pt;">Actual results could differ from those estimates.</span></div>

CY2019	us-gaap	Direct Financing Lease Risk Strategy Residual Asset DirectFinancingLeaseRiskStrategyResidualAsset	Our allowance for loan losses for financing leases considers both the collectability of the lease payments receivable as well as the estimated residual value of the leased asset. We typically purchase residual value insurance on our financing leases so that our risk of loss at lease termination will be less than 10% of the initial value of the lease. In addition, we have several channels for re-leasing or marketing those assets.
