Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1: Summary of Significant Accounting Policies Wells Fargo Real Estate Investment Corporation (the Company, we, our or us) is an indirect subsidiary of both Wells Fargo & Company (Wells Fargo) and Wells Fargo Bank, National Association (the Bank). The Company, a Delaware corporation, has operated as a real estate investment trust (REIT) since its formation in 1996. Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. 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 related to the allowance for credit losses (Note 2 (Loans and Allowance for Credit Losses)). Actual results could differ from those estimates. Accounting Standards Adopted in 2018 In 2018 , we adopted the following new accounting guidance: • Accounting Standards Update (ASU or Update) 2016-15 – Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments; • ASU 2016-01 – Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities; and • ASU 2014-09 – Revenue from Contracts With Customers (Topic 606) and subsequent related Updates. ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice for reporting in the statement of cash flows. We adopted this change in first quarter 2018. The Update did not have any impact on our financial statements. ASU 2016-01 changes the accounting for certain equity securities to record at fair value with unrealized gains or losses reflected in earnings, as well as improve the disclosures of equity securities and the fair value of financial instruments. We do not have equity securities. Accordingly, the impact to our financial statements is limited to our disclosure of the fair value of financial instruments. The valuation methodologies for estimating the fair value of financial instruments that are recorded at amortized cost, including loans, has been changed to conform with an exit price notion. ASU 2014-09 modifies the guidance used to recognize revenue from contracts with customers for transfers of goods or services and transfers of nonfinancial assets, unless those contracts are within the scope of other guidance. Our revenue is from net interest income on financial assets and pledge fees, which are both excluded from the scope of the guidance. Accordingly, there is no impact on our financial statements. Third Quarter 2016 Common Stock Issuance and Related Loan Acquisitions On August 26, 2016, the Company issued and sold 21.2 million shares of common stock to affiliates of the Company for an aggregate purchase price of $20.0 billion . Following the issuance, indirect wholly-owned subsidiaries of the Bank continue to own 100% of the Company’s common stock. Subsequent to the issuance, the Company used the proceeds, as well as proceeds from loan paydowns and payoffs, to acquire $19.1 billion of real estate 1-4 family first mortgage loans and $1.9 billion of commercial secured by real estate loans. Cash and Cash Equivalents Cash and cash equivalents include cash and amounts due from banks and interest-bearing bank balances. Generally, cash and cash equivalents have maturities of three months or less, and accordingly, the carrying amount of these instruments is considered to be a reasonable estimate of fair value. Loans We have acquired, or accepted as capital contributions, participation interests in loans both secured and not secured by real estate along with other assets. We anticipate that we will acquire, or receive as capital contributions, loans or other assets from the Bank pursuant to loan participation and servicing and assignment agreements among the Bank, certain of its subsidiaries and us. Substantially all of our interests in mortgage loans and other assets have been acquired from the Bank pursuant to loan participation and servicing and assignment agreements. The Bank originated the loans, purchased them from other financial institutions or acquired them as part of the acquisition of other financial institutions. Substantially all of our loans are serviced by the Bank. In general, the Bank initially transfers participation interests in loans to a subsidiary of the Bank that does not have a direct or indirect ownership interest in us, which then transfers such participation interests to us. We may from time to time transfer such participation interests back to the subsidiary, which may ultimately transfer such interests back to the Bank. In 2018 , we acquired $3.3 billion of participation interests in consumer loans and $423.4 million of participation interests in commercial loans directly from the Bank. Pursuant to the terms of the relevant participation and servicing and assignment agreements, we generally may not sell, transfer, encumber, assign, pledge or hypothecate our participation interests in loans without the prior written consent of the Bank. As such, t he transfers do not qualify for sale accounting; however the assets continue to be classified as loans in our financial statements because the returns and recoverability of these non-recourse receivables are entirely dependent on the performance of the underlying loans. The Company initially measures the non-recourse receivables at the cash proceeds exchanged which represents the fair value of the transferred loans. During 2018, we modified our consumer loan participation and servicing agreements, which has removed the restrictions that prevented sale accounting. In 2018 , we acquired $3.3 billion of consumer loans under these modified loan participation and servicing agreements. The assets are classified as loans in our financial statements and initially recorded at fair value. Loans are recorded at the principal balance outstanding, net of any cumulative charge-offs and unamortized premium or discount on acquired loans. Interest income is recognized on an accrual basis. Premiums and discounts are amortized as an adjustment to the yield over the contractual life of the loan using the interest method. If a prepayment occurs on a loan, any related premium or discount is recognized as an adjustment to yield in the results of operations in the period in which the prepayment occurs. Loans acquired in a transfer, including business combinations where there is evidence of credit deterioration since origination and it is probable at the date of acquisition that we will not collect all contractually required principal and interest payments, are accounted for as purchased credit-impaired (PCI) loans. Substantially all of our PCI loans were acquired in the December 31, 2008 acquisition of Wachovia Corporation by Wells Fargo. PCI loans are initially recorded at fair value, which includes estimated future credit losses expected to be incurred over the life of the loan. Accordingly, the historical allowance for credit losses is not carried over. A nonaccretable difference is established for PCI loans to absorb losses expected on those loans at the date of acquisition. Amounts absorbed by the nonaccretable difference do not affect the income statement or the allowance for credit losses. PCI loans were less than 1 percent of total loans at December 31, 2018 and 2017 . Nonaccrual and Past Due Loans We generally place loans on nonaccrual status when: • the full and timely collection of interest or principal becomes uncertain (generally based on an assessment of the borrower’s financial condition and the adequacy of collateral, if any), such as in bankruptcy or other circumstances; • they are 90 days ( 120 days with respect to real estate 1-4 family first and junior lien mortgages) past due for interest or principal, unless both well-secured and in the process of collection; • part of the principal balance has been charged off; or • for junior lien mortgages, we have evidence that the related first lien mortgage may be 120 days past due or in the process of foreclosure regardless of the junior lien delinquency status. PCI loans are written down at acquisition to fair value using an estimate of cash flows deemed to be collectible and an accretable yield is established. Accordingly, such loans are not classified as nonaccrual because they continue to earn interest from accretable yield, independent of performance in accordance of their contractual terms, and we expect to fully collect the new carrying values of such loans (that is, the new cost basis arising out of purchase accounting). When we place a loan on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend amortization of any net deferred fees. If the ultimate collectability of the recorded loan balance is in doubt on a nonaccrual loan, the cost recovery method is used and cash collected is applied to first reduce the carrying value of the loan. Otherwise, interest income may be recognized to the extent cash is received. Generally, we return a loan to accrual status when all delinquent interest and principal become current under the terms of the loan agreement and collectability of remaining principal and interest is no longer doubtful. We typically re-underwrite modified loans at the time of a restructuring to determine if there is sufficient evidence of sustained repayment capacity based on the borrower’s financial strength, including documented income, debt to income ratios and other factors. If the borrower has demonstrated performance under the previous terms and the underwriting process shows the capacity to continue to perform under the restructured terms, the loan will generally remain in accruing status. When a loan classified as a troubled debt restructuring (TDR) performs in accordance with its modified terms, the loan either continues to accrue interest (for performing loans) or will return to accrual status after the borrower demonstrates a sustained period of performance (generally six consecutive months of payments, or equivalent, inclusive of consecutive payments made prior to the modification). Loans will be placed on nonaccrual status and a corresponding charge-off is recorded if we believe it is probable that principal and interest contractually due under the modified terms of the agreement will not be collectible. Our loans are considered past due when contractually required principal or interest payments have not been made on the due dates. Loan Charge-off Policies For commercial loans, we generally fully charge off or charge down to net realizable value (fair value of collateral, less estimated costs to sell) for loans secured by collateral when: • management judges the loan to be uncollectible; • repayment is deemed to be protracted beyond reasonable time frames; • the loan has been classified as a loss by either our internal loan review process or our banking regulatory agencies; • the customer has filed bankruptcy and the loss becomes evident owing to a lack of assets; or • the loan is 180 days past due unless both well-secured and in the process of collection. For consumer loans, we fully charge off or charge down to net realizable value when deemed uncollectible due to bankruptcy or other factors, or no later than when the loan is 180 days past due. Impaired Loans We consider a loan to be impaired when, based on current information and events, we determine that we will not be able to collect all amounts due according to the loan contract, including scheduled interest payments. This evaluation is generally based on delinquency information, an assessment of the borrower’s financial condition and the adequacy of collateral, if any. Our impaired loans predominantly include loans on nonaccrual status in the commercial portfolio segment and loans modified in a TDR, whether on accrual or nonaccrual status. When we identify a loan as impaired, we generally measure the impairment, if any, based on the difference between the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount) and the present value of expected future cash flows, discounted at the loan’s effective interest rate. When the value of an impaired loan is calculated by discounting expected cash flows, interest income is recognized using the loan’s effective interest rate over the remaining life of the loan. When collateral is the sole source of repayment for the impaired loan, rather than the borrower’s income or other sources of repayment, we charge down to net realizable value. Troubled Debt Restructurings In situations where, for economic or legal reasons related to a borrower’s financial difficulties, we grant a concession for other than an insignificant period of time to the borrower that we would not otherwise consider, the related loan is classified as a TDR. These modified terms may include rate reductions, principal forgiveness, term extensions, payment forbearance and other actions intended to minimize our economic loss and to avoid foreclosure or repossession of the collateral, if applicable. For modifications where we forgive principal, the entire amount of such principal forgiveness is immediately charged off. Loans classified as TDRs, including loans in trial payment periods (trial modifications), are considered impaired loans. Other than resolutions such as foreclosures and sales, we may remove loans held for investment from TDR classification, but only if they have been refinanced or restructured at market terms and qualify as a new loan. Foreclosed Assets Foreclosed assets obtained through our lending activities primarily include real estate. Generally, loans have been written down to their net realizable value prior to foreclosure. Any further reduction to their net realizable value is recorded with a charge to the allowance for credit losses at foreclosure. We allow up to 90 days after foreclosure to finalize determination of net realizable value. Thereafter, changes in net realizable value are recorded to foreclosed assets expense. The net realizable value of these assets is reviewed and updated periodically depending on the type of property. Allowance for Credit Losses (ACL) The ACL is management’s estimate of credit losses inherent in the loan portfolio, including unfunded credit commitments, at the balance sheet date. We have an established process to determine the appropriateness of the ACL that assesses the losses inherent in our portfolio and related unfunded credit commitments. While we attribute portions of the allowance to our respective commercial and consumer portfolio segments, the entire allowance is available to absorb credit losses inherent in the total loan portfolio and unfunded credit commitments. We develop and document our allowance methodology at the portfolio segment level - commercial loan portfolio and consumer loan portfolio. Our process involves procedures to appropriately consider the unique risk characteristics of our commercial and consumer loan portfolio segments. For each portfolio segment, losses are estimated collectively for groups of loans with similar characteristics, individually or pooled for impaired loans or, for PCI loans, based on the changes in cash flows expected to be collected. Our allowance levels are influenced by loan volumes, loan grade migration or delinquency status, historic loss experience and other conditions influencing loss expectations, such as economic conditions. COMMERCIAL PORTFOLIO SEGMENT ACL METHODOLOGY Generally, commercial loans are assessed for estimated losses by grading each loan using various risk factors as identified through periodic reviews. Our estimation approach for the commercial portfolio reflects the estimated probability of default in accordance with the borrower’s financial strength, and the severity of loss in the event of default, considering the quality of any underlying collateral. Probability of default and severity at the time of default are statistically derived through historical observations of default and losses after default within each credit risk rating. These estimates are adjusted as appropriate based on additional analysis of long-term average loss experience compared to previously forecasted losses, external loss data or other risks identified from current economic conditions and credit quality trends. The estimated probability of default and severity at the time of default are applied to loan equivalent exposures to estimate losses for unfunded credit commitments. The allowance also includes an amount for the estimated impairment on nonaccrual commercial loans and commercial loans modified in a TDR, whether on accrual or nonaccrual status. CONSUMER PORTFOLIO SEGMENT ACL METHODOLOGY For consumer loans that are not identified as a TDR, we generally determine the allowance on a collective basis utilizing forecasted losses to represent our best estimate of inherent loss. We pool loans, generally by product types with similar risk characteristics, such as residential real estate mortgages. As appropriate and to achieve greater accuracy, we may further stratify selected portfolios by sub-product, origination channel, vintage, loss type, geographic location and other predictive characteristics. Models designed for each pool are utilized to develop the loss estimates. We use assumptions for these pools in our forecast models, such as historic delinquency and default, loss severity, home price trends, unemployment trends, and other key economic variables that may influence the frequency and severity of losses in the pool. In determining the appropriate allowance attributable to our residential mortgage portfolio, we take into consideration portfolios determined to be at elevated risk, such as junior lien mortgages behind delinquent first lien mortgages. We incorporate the default rates and severity of loss for these higher risk portfolios, including the impact of our established loan modification programs. Accordingly, the loss content associated with the effects of loan modifications and higher risk portfolios has been captured in our ACL methodology. We separately estimate impairment for consumer loans that have been modified in a TDR (including trial modifications), whether on accrual or nonaccrual status. OTHER ACL MATTERS The allowance for credit losses for both portfolio segments includes an amount for imprecision or uncertainty that may change from period to period. This amount represents management’s judgment of risks inherent in the processes and assumptions used in establishing the allowance. This imprecision considers economic environmental factors, modeling assumptions and performance, process risk, and other subjective factors, including industry trends and emerging risk assessments. Fair Value of Financial Instruments We use fair value measurements in our fair value disclosures and to record certain assets and liabilities at fair value. We base our fair values on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. These fair value measurements are based on the exit price notion and are determined by maximizing the use of observable inputs. However, for certain instruments, we must utilize unobservable inputs in determining fair value due to the lack of observable inputs in the market, which requires greater judgment in the measurement of fair value . Income Taxes We are taxed as a REIT under relevant sections of the Internal Revenue Code of 1986 (the Code). A REIT is generally not subject to federal income tax to the extent it complies with the relevant provisions of the Code, including distributing substantially all of its taxable earnings to shareholders, and as long as certain asset, income and stock ownership tests are met. For the tax years ended December 31, 2018 , 2017 , and 2016 , we complied with these provisions and are not subject to federal income tax. As a REIT, dividends paid on preferred and common shares generally constitute ordinary income to the shareholder. However, distributions paid on common shares in excess of REIT taxable income, computed without regard to the dividends paid deduction, do not qualify as dividend income, and instead constitute a return of capital. In the event we do not continue to qualify as a REIT, earnings and cash provided by operating activities available for distribution to shareholders would be reduced by the amount of any applicable income tax obligation. The preferred and common dividends we pay as a REIT are ordinary investment income not eligible for the dividends received deduction for corporate shareholders or for the favorable qualified dividend tax rate applicable to non-corporate taxpayers, however beginning in 2018 non-corporate shareholders may be able to deduct 20% of the preferred and common dividends as a deduction for qualified business income under the Tax Cuts & Jobs Act enacted December 22, 2017. If we were not a REIT, preferred and common dividends we pay generally would qualify for the dividends received deduction for corporate shareholders and the favorable qualified dividend tax rate applicable to non-corporate taxpayers. We file a separate federal income tax return and therefore are not included in the Wells Fargo consolidated tax returns or subject to the allocation of federal income tax liability (benefit) resulting from these consolidated tax returns. In addition, we will file unitary state income tax returns along with other subsidiaries of Wells Fargo. We evaluate uncertain tax positions in accordance with FASB ASC 740, Income Taxes . Based upon our current evaluation, we have concluded that there are no significant uncertain tax positions relevant to the jurisdictions where we are required to file income tax returns requiring recognition in the financial statements at December 31, 2018 , 2017 , and 2016 . We are not subject to federal income tax examinations for tax years prior to 2015 or, with few exceptions, state examinations prior to 2011. Earnings Per Common Share We compute basic earnings per share by dividing income available to common stockholders by the weighted average number of shares of common stock outstanding for the period. We compute diluted earnings per share by dividing income available to common stockholders by the sum of the weighted average number of shares adjusted to include the effect of potentially dilutive shares. Income available to common stockholders is computed as net income less dividends on preferred stock. There were no potentially dilutive shares in any period presented and accordingly, basic and diluted earnings per share are the same. Retained Earnings (Deficit) We expect to distribute annually an aggregate amount of dividends with respect to outstanding capital stock equal to approximately 100 percent of our REIT taxable income for federal income tax purposes. Because our net income determined under GAAP may vary from the determination of REIT taxable income, periodic distributions may exceed our GAAP net income. The retained deficit included within our balance sheet results from cumulative distributions that have exceeded GAAP net income, predominantly due to the impact on REIT taxable income of purchase accounting adjustments attributable to the Company during the years 2009 through 2013, from the 2008 acquisition of Wachovia Corporation by Wells Fargo. The remaining purchase accounting adjustments at December 31, 2018 and 2017 , are not significant. Subsequent Events We have evaluated the effects of events that have occurred subsequent to December 31, 2018 , and there have been no material events that would require recognition in our 2018 financial statements or disclosure in the Notes to the financial statements.

Loans and Allowance for Credit Losses	Note 2: Loans and Allowance for Credit Losses The Company acquires loans originated or purchased by the Bank. In order to maintain our status as a REIT, the composition of the loans is highly concentrated in real estate. Underlying loans are concentrated primarily in California , New York , Washington , Virginia and Texas . These markets include approximately 54% of our total loan balance at December 31, 2018 . The following table presents total loans outstanding by portfolio segment and class of financing receivable. Total reductions and additions for unamortized premiums, discounts and other adjustments were less than 1% of outstanding balances at December 31, 2018 and 2017 .

Credit Quality We monitor credit quality by evaluating various attributes and utilize such information in our evaluation of the appropriateness of the allowance for credit losses. The following sections provide the credit quality indicators we most closely monitor. The credit quality indicators are generally based on information as of our financial statement date, with the exception of updated Fair Isaac Corporation (FICO) scores and updated loan-to-value (LTV)/combined LTV (CLTV). We obtain FICO scores at loan origination and the scores are generally updated at least quarterly, except in limited circumstances, including compliance with the Fair Credit Reporting Act (FCRA). Generally, the LTV and CLTV indicators are updated in the second month of each quarter, with updates no older than September 30, 2018 . COMMERCIAL CREDIT QUALITY INDICATORS In addition to monitoring commercial loan concentration risk, we manage a consistent process for assessing commercial loan credit quality. Generally commercial loans are subject to individual risk assessment using our internal borrower and collateral quality ratings. Our ratings are aligned to Pass and Criticized categories. The Criticized category includes Special Mention, Substandard, and Doubtful categories which are defined by bank regulatory agencies. The table below provides a breakdown of outstanding commercial loans by risk category. (in thousands) Total December 31, 2018 By risk category: Pass $ 3,016,328 Criticized 39,095 Total commercial loans $ 3,055,423 December 31, 2017 By risk category: Pass $ 3,316,604 Criticized 9,335 Total commercial loans $ 3,325,939 The following table provides past due information for commercial loans, which we monitor as part of our credit risk management practices.

Loan delinquency, FICO credit scores and LTV/CLTV for loan types are common credit quality indicators that we monitor and utilize in our evaluation of the appropriateness of the allowance for credit losses for the consumer portfolio segment. Many of our loss estimation techniques used for the allowance for credit losses rely on delinquency-based models; therefore, delinquency is an important indicator of credit quality and the establishment of our allowance for credit losses.

CLTV refers to the combination of first mortgage and junior lien mortgage ratios. LTVs and CLTVs are updated quarterly using a cascade approach which first uses values provided by automated valuation models (AVMs) for the property. If an AVM is not available, then the value is estimated using the original appraised value adjusted by the change in Home Price Index (HPI) for the property location. If an HPI is not available, the original appraised value is used. The HPI value is normally the only method considered for high value properties, generally with an original value of $1 million or more, as the AVM values have proven less accurate for these properties. The following table shows the most updated LTV and CLTV distribution of the real estate 1-4 family first and junior lien mortgage loan portfolios. We consider the trends in residential real estate markets as we monitor credit risk and establish our allowance for credit losses. In the event of a default, any loss should be limited to the portion of the loan amount in excess of the net realizable value of the underlying real estate collateral value. Certain loans do not have an LTV or CLTV due to industry data availability and portfolios acquired from or serviced by other institutions.

In the event of default, the loss content would generally be limited to only the amount in excess of 100% LTV/CLTV. NONACCRUAL LOANS The following table provides loans on nonaccrual status. PCI loans are excluded from this table due to the existence of the accretable yield, independent of performance in accordance with their contractual terms. December 31, (in thousands) 2018 2017 Total commercial $ 1,975 2,306 Consumer: Real estate 1-4 family first mortgage 142,325 150,381 Real estate 1-4 family junior lien mortgage 34,625 44,703 Total consumer 176,950 195,084 Total nonaccrual loans (excluding PCI) $ 178,925 197,390 LOANS IN PROCESS OF FORECLOSURE Our recorded investment in consumer mortgage loans collateralized by residential real estate property that are in process of foreclosure was $46.4 million and $41.7 million at December 31, 2018 and 2017 , respectively, and none of these loans are government insured/guaranteed. We commence the foreclosure process on consumer real estate loans when a borrower becomes 120 days delinquent in accordance with Consumer Finance Protection Bureau Guidelines. Foreclosure procedures and timelines vary depending on whether the property address resides in a judicial or non-judicial state. Judicial states require the foreclosure to be processed through the state’s courts while non-judicial states are processed without court intervention. Foreclosure timelines vary according to state law. LOANS 90 DAYS OR MORE PAST DUE AND STILL ACCRUING Certain loans 90 days or more past due as to interest or principal are still accruing, because they are (1) well-secured and in the process of collection or (2) real estate 1-4 family mortgage loans exempt under regulatory rules from being classified as nonaccrual until later delinquency, usually 120 days past due. PCI loans of $373 thousand at December 31, 2018 , and $699 thousand at December 31, 2017 , are excluded from this disclosure even though they are 90 days or more contractually past due. These PCI loans are considered to be accruing because they continue to earn interest from accretable yield, independent of performance in accordance with their contractual terms. The following table shows non-PCI loans 90 days or more past due and still accruing.

Our impaired loans predominantly include loans on nonaccrual status in the commercial portfolio segment and loans modified in a TDR, whether on accrual or nonaccrual status. These impaired loans generally have estimated losses which are included in the allowance for credit losses. We have impaired loans with no allowance for credit losses when loss content has been previously recognized through charge-offs and we do not anticipate additional charge-offs or losses, or certain loans are currently performing in accordance with their terms and for which no loss has been estimated. Impaired loans exclude PCI loans. The table below includes trial modifications that totaled $5.3 million at December 31, 2018 , and $7.5 million at December 31, 2017 .

Troubled Debt Restructuring (TDRs) When, for economic or legal reasons related to a borrower’s financial difficulties, we grant a concession for other than an insignificant period of time to a borrower that we would not otherwise consider, the related loan is classified as a TDR, the balance of which totaled $363.1 million and $409.7 million at December 31, 2018 and 2017 , respectively. We do not consider loan resolutions, such as foreclosure or short sale, to be a TDR. We may require some consumer borrowers experiencing financial difficulty to make trial payments generally for a period of three to four months, according to the terms of a planned permanent modification, to determine if they can perform according to those terms. These arrangements represent trial modifications, which we classify and account for as TDRs. While loans are in trial payment programs, their original terms are not considered modified and they continue to advance through delinquency status and accrue interest according to their original terms. The following table summarizes our TDR modifications for the periods presented by primary modification type and includes the financial effects of these modifications.

TDRs may have multiple types of concessions, but are presented only once in the first modification type based on the order presented in the table above. The reported amounts include loans remodified of $11.4 million , $8.5 million , and $8.8 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. (2) Principal modifications include principal forgiveness at the time of the modification, contingent principal forgiveness granted over the life of the loan based on borrower performance, and principal that has been legally separated and deferred to the end of the loan, with a zero percent contractual interest rate. (3) Other concessions include loans discharged in bankruptcy, loan renewals, term extensions and other interest and noninterest adjustments, but exclude modifications that also forgive principal and/or reduce the contractual interest rate. (4) Charge-offs include write-downs of the investment in the loan in the period it is contractually modified. The amount of charge-off will differ from the modification terms if the loan has been charged down prior to the modification based on our policies. In addition, there may be cases where we have a charge-off/down with no legal principal modification. Modifications resulted in legally forgiving principal (actual, contingent or deferred) of $649 thousand , $1.0 million and $1.2 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. (5) Reflects the effect of reduced interest rates on loans with an interest rate concession as one of their concession types, which includes loans reported as a principal primary modification type that also have an interest rate concession. (6) Trial modifications are granted a delay in payments due under the original terms during the trial payment period. However, these loans continue to advance through delinquency status and accrue interest according to their original terms. Any subsequent permanent modification generally includes interest rate related concessions; however, the exact concession type and resulting financial effect are usually not known until the loan is permanently modified. Trial modifications for the period are presented net of previously reported trial modifications that became permanent in the current period. The table below summarizes permanent modification TDRs that have defaulted in the current period within 12 months of their permanent modification date. We report these defaulted TDRs based on a payment default definition of 90 days past due for the commercial portfolio segment and 60 days past due for the consumer portfolio segment.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Guarantees and Other Matters	Note 3: Commitments, Guarantees and Other Matters The Company does not have any consumer lines of credit. Its commercial loan portfolio includes unfunded loan commitments that are provided in the normal course of business. For commercial borrowers, loan commitments generally take the form of revolving credit arrangements to finance their working capital requirements. These instruments are not recorded on the balance sheet until funds are advanced under the commitment. The contractual amount of a lending commitment represents the maximum potential credit risk if it is fully funded and the borrower does not perform according to the terms of the contract. Some of these commitments expire without being funded, and accordingly, total contractual amounts are not representative of actual future credit exposure or liquidity requirements. Loan commitments create credit risk in the event that the counterparty draws on the commitment and subsequently fails to perform under the terms of the lending agreement. This risk is incorporated into our overall evaluation of credit risk, and to the extent necessary, an allowance for credit losses is recorded on these commitments. Uncertainties around the timing and amount of funding under these commitments may create liquidity risk for the Company. The following table provides the contract or notional amount and the estimated fair value of commercial loan commitments to extend credit. The fair value of commitments to extend credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the current creditworthiness of the counterparties. The estimated fair value of lending commitments represents the estimated amount that we would need to pay a third party to assume our exposure on lending commitments. Dec 31, Dec 31, (in thousands) 2018 2017 Commercial: Lines of credit $ 453,603 488,158 Standby letters of credit 8,592 19,680 Total commercial loan commitments (1) $ 462,195 507,838 (1) The estimated fair value of commitments to extend credit at December 31, 2018 and 2017 , was $1.5 million and $1.3 million , respectively. As part of the loan participation and servicing and assignment agreements with the Bank, the Company provides an indemnification to the Bank if certain events occur. These contingencies generally relate to claims or judgments arising out of participated loans that are not the result of gross negligence or intentional misconduct by the Bank. We were not required to make payments under the indemnification clauses in 2018 or 2017 . Since there are no stated or notional amounts included in the indemnification clauses and the contingencies triggering the obligation to indemnify have not occurred and are not expected to occur, we are not able to estimate the maximum amount of future payments under the indemnification clauses. There are no amounts reflected on the balance sheet at December 31, 2018 and 2017 , related to these indemnifications. The Company is not currently involved in, nor, to our knowledge, currently threatened with any material litigation. From time to time we may become involved in routine litigation arising in the ordinary course of business. We do not believe that the eventual outcome of any such routine litigation will, in the aggregate, have a materially adverse effect on our financial statements. However, in the event of unexpected future developments, it is possible that the ultimate resolution of those matters, if unfavorable, could be material to our financial statements for any particular period.

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Note 4: Fair Values of Assets and Liabilities We use fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. We did not elect the fair value option for any financial instruments as permitted in FASB ASC 825, Financial Instruments , which allows companies to elect to carry certain financial instruments at fair value with corresponding changes in fair value reported in the results of operations. See Note 1 (Summary of Significant Accounting Policies) for additional information about our fair value measurement policies and methods. Fair Value Hierarchy We group our assets and liabilities measured at fair value in three levels based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level 1 – Valuation is based upon quoted prices for identical instruments traded in active markets. • Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. • Level 3 – Valuation is generated from techniques that use significant assumptions that are not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. In the determination of the classification of financial instruments in Level 2 or Level 3 of the fair value hierarchy, we consider all available information, including observable market data, indications of market liquidity and orderliness, and our understanding of the valuation techniques and significant inputs used. Based upon the specific facts and circumstances of each instrument or instrument category, we make judgments regarding the significance of the Level 3 inputs to the instruments' fair value measurement in its entirety. If Level 3 inputs are considered significant, the instrument is classified as Level 3. Loans We do not record loans at fair value on a recurring basis. However, from time to time, we record nonrecurring fair value adjustments to loans to primarily reflect partial write-downs that are based on the observable market price of the loan or current appraised value of the collateral. As of December 31, 2018 and 2017 , assets measured at fair value on a nonrecurring basis were less than 1 percent of total assets. Disclosures about Fair Value of Financial Instruments The table below is a summary of fair value estimates by level for financial instruments. In connection with the adoption of ASU 2016-01 in first quarter 2018, the valuation methodologies for estimating the fair value of financial instruments that are recorded at amortized cost, including loans, has been changed, where necessary, to conform with an exit price notion. Under an exit price notion, fair value estimates are based upon the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the balance sheet date. For certain loans the estimated fair values prior to adoption of ASU 2016-01 followed an entrance price notion that based fair values on recent prices offered to customers for loans with similar characteristics. The carrying amounts in the following table are recorded in the balance sheet under the indicated captions. We have not included assets and liabilities that are not financial instruments in our disclosure, such as other assets and other liabilities. The total of the fair value calculations presented does not represent, and should not be construed to represent, the underlying value of the Company.

With respect to the payment of dividends and liquidation preference, the Series A preferred stock ranks on parity with Series B preferred stock and senior to the Company’s common stock. The Company may issue additional shares of common stock to affiliates of Wells Fargo without further action by the Series A or Series B stockholders. The certificate of designation for the Series A preferred stock limits our ability to pay dividends on our common stock or make any payment of interest or principal on our line of credit with the Bank if the dividend coverage ratio for the four prior fiscal quarters is less than 150% . The dividend coverage ratio, expressed as a percentage, is calculated by dividing the four prior fiscal quarters’ funds from operations, defined as GAAP net income excluding gains or losses from sales of property, by the amount that would be required to pay annual dividends on the Series A and Series B preferred stock. At December 31, 2018 , the dividend coverage ratio was 7,037% . The certificate of designation for the Series A preferred stock also contains a covenant in which we may incur indebtedness in an aggregate amount not exceeding 20% of our stockholders’ equity. Any amount exceeding that amount requires the consent of the holders of two-thirds of the Series A preferred stock, voting as a separate class. Except upon the occurrence of a Special Event (as defined below), the Series A preferred stock is not redeemable prior to December 11, 2019. On or after such date, we may redeem the Series A preferred stock for cash, in whole or in part, at the redemption price of $25 per share, plus (a) any authorized, declared, but unpaid dividends and (b) any accumulated but unpaid dividends to the date of redemption. A Special Event, which allows redemption of the Series A preferred stock prior to December 11, 2019, means: a Tax Event, an Investment Company Act Event, or a Regulatory Event. Tax Event means our determination, based on the receipt by us of an opinion of counsel, rendered by a law firm experienced in such matters, in form and substance satisfactory to us, which states that there is a significant risk that dividends paid or to be paid by us with respect to our capital stock are not or will not be fully deductible by us for United States Federal income tax purposes or that we are or will be subject to additional taxes, duties, or other governmental charges, in an amount we reasonably determine to be significant as a result of: • any amendment to, clarification of, or change in, the laws, treaties, or related regulations of the United States or any of its political subdivisions or their taxing authorities affecting taxation; or • any judicial decision, official administrative pronouncement, published or private ruling, technical advice memorandum, Chief Counsel Advice, as such term is defined in the Code, regulatory procedure, notice, or official announcement which amendment, clarification, or change, or such official pronouncement or decision, is announced on or after the original date of issuance of the Series A preferred stock. Investment Company Act Event means our determination, based on our receipt of an opinion of counsel, rendered by a law firm experienced in such matters, in form and substance satisfactory to us, which states that there is a significant risk that we are or will be considered an “investment company” that is required to be registered under the Investment Company Act, as a result of the occurrence of a change in law or regulation or a written change in interpretation or application of law or regulation, by any legislative body, court, governmental agency, or regulatory authority. Regulatory Event means our reasonable determination, as evidenced by a certificate of one of our senior executive officers, that the Series A preferred stock remaining outstanding would (a) not be consistent with any applicable law or regulation or (b) have a material adverse effect on either us or any of Wells Fargo or the Bank (or any of their respective successors), in each case, as a result of a change in law or regulation or a written change in interpretation or application of law or regulation, by any legislative body, court, governmental agency, or regulatory authority occurring on or after the original date of issuance of the Series A preferred stock, such change in law being reflected in an opinion of counsel, in form and substance satisfactory to us. The Series B preferred stock can be redeemed by us in whole at any time at $1,000 per share plus any accumulated and unpaid dividends. Transfers or pledges of the Series B shares are subject to first refusal by us.

Due to the common ownership of the Company and the affiliated parties by Wells Fargo, these transactions and agreements may reflect circumstances and considerations that could differ from those conducted with unaffiliated parties. The principal items related to transactions with affiliated parties included in the accompanying statement of income and balance sheet are described in the table and narrative below.

Loans We acquire and sell loans to and from the Bank. The acquisitions and sales are transacted at fair value resulting in acquisition discounts and premiums or gains and losses on sales. The net acquisition discount accretion or premium amortization is reported within interest income. Gains or losses on sales of loans are included within noninterest income. Losses on sales of loans to the Bank were $88 thousand in 2018 , compared with $844 thousand in 2017 and $2.7 million in 2016 . The certificate of designation for the Series A preferred stock limits our ability to pledge loans to an aggregate amount not exceeding 80% of our total assets at any time as collateral on behalf of the Bank for the Bank’s access to secured borrowing facilities through the Federal Home Loan Banks or the discount window of Federal Reserve Banks. In exchange for the pledge of our loan assets, the Bank pays us a fee that is consistent with market terms. At December 31, 2018 , the fee was equal to an annual rate of 17 basis points ( 0.17% ) as applied to the unpaid principal balance of pledged loans on a monthly basis. At December 31, 2017 , the fee was equal to an annual rate of 15 basis points ( 0.15% ). Prior to November 2017, the fee was equal to an annual rate of 34 basis points ( 0.34% ). Such fee may be renegotiated by us and the Bank from time to time. Loan Servicing Costs The loans in our portfolio are predominantly serviced by the Bank pursuant to the terms of participation and servicing and assignment agreements. In some instances, the Bank has delegated servicing responsibility to third parties that are not affiliated with us or the Bank. Depending on the loan type, the monthly servicing fee charges are based in part on (a) outstanding principal balances, (b) a flat fee per month, or (c) a total loan commitment amount. Management Fees We pay the Bank a management fee to reimburse for general overhead expenses, including allocations of technology support and a combination of finance and accounting, risk management and other general overhead expenses incurred on our behalf. Management fees include direct and indirect expense allocations. Indirect expenses are allocated based on ratios that use our proportion of expense activity drivers. The expense activity drivers and ratios may change from time to time. Deposits Interest income earned on deposits is included in interest income. Our cash management process includes applying operating cash flows to reduce any outstanding balance on our line of credit with the Bank. Operating cash flows are settled through our affiliate accounts receivable/payable process. Upon settlement cash received is either applied to reduce our line of credit outstanding or retained as a deposit with the Bank. Foreclosed Assets We sell foreclosed assets back to the Bank from time to time at estimated fair value. Line of Credit We have a revolving line of credit with the Bank pursuant to which we can borrow up to $5.0 billion at a rate of interest equal to the three-month London Interbank Offered Rate plus 4.4 basis points ( 0.044% ). Accounts Payable and Receivable - Affiliates, Net Accounts payable and receivable from affiliates result from intercompany transactions in the normal course of business related to loan paydowns and payoffs, interest receipts, servicing costs, management fees and other transactions with the Bank or its affiliates.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Significant Accounting Policies [Line Items]
Nature of Operations	Wells Fargo Real Estate Investment Corporation (the Company, we, our or us) is an indirect subsidiary of both Wells Fargo & Company (Wells Fargo) and Wells Fargo Bank, National Association (the Bank). The Company, a Delaware corporation, has operated as a real estate investment trust (REIT) since its formation in 1996.
Use of estimates	Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. 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 related to the allowance for credit losses (Note 2 (Loans and Allowance for Credit Losses)). Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and amounts due from banks and interest-bearing bank balances. Generally, cash and cash equivalents have maturities of three months or less, and accordingly, the carrying amount of these instruments is considered to be a reasonable estimate of fair value.
Loans	Loans We have acquired, or accepted as capital contributions, participation interests in loans both secured and not secured by real estate along with other assets. We anticipate that we will acquire, or receive as capital contributions, loans or other assets from the Bank pursuant to loan participation and servicing and assignment agreements among the Bank, certain of its subsidiaries and us. Substantially all of our interests in mortgage loans and other assets have been acquired from the Bank pursuant to loan participation and servicing and assignment agreements. The Bank originated the loans, purchased them from other financial institutions or acquired them as part of the acquisition of other financial institutions. Substantially all of our loans are serviced by the Bank. In general, the Bank initially transfers participation interests in loans to a subsidiary of the Bank that does not have a direct or indirect ownership interest in us, which then transfers such participation interests to us. We may from time to time transfer such participation interests back to the subsidiary, which may ultimately transfer such interests back to the Bank. In 2018 , we acquired $3.3 billion of participation interests in consumer loans and $423.4 million of participation interests in commercial loans directly from the Bank. Pursuant to the terms of the relevant participation and servicing and assignment agreements, we generally may not sell, transfer, encumber, assign, pledge or hypothecate our participation interests in loans without the prior written consent of the Bank. As such, t he transfers do not qualify for sale accounting; however the assets continue to be classified as loans in our financial statements because the returns and recoverability of these non-recourse receivables are entirely dependent on the performance of the underlying loans. The Company initially measures the non-recourse receivables at the cash proceeds exchanged which represents the fair value of the transferred loans. During 2018, we modified our consumer loan participation and servicing agreements, which has removed the restrictions that prevented sale accounting. In 2018 , we acquired $3.3 billion of consumer loans under these modified loan participation and servicing agreements. The assets are classified as loans in our financial statements and initially recorded at fair value. Loans are recorded at the principal balance outstanding, net of any cumulative charge-offs and unamortized premium or discount on acquired loans. Interest income is recognized on an accrual basis. Premiums and discounts are amortized as an adjustment to the yield over the contractual life of the loan using the interest method. If a prepayment occurs on a loan, any related premium or discount is recognized as an adjustment to yield in the results of operations in the period in which the prepayment occurs. Loans acquired in a transfer, including business combinations where there is evidence of credit deterioration since origination and it is probable at the date of acquisition that we will not collect all contractually required principal and interest payments, are accounted for as purchased credit-impaired (PCI) loans. Substantially all of our PCI loans were acquired in the December 31, 2008 acquisition of Wachovia Corporation by Wells Fargo. PCI loans are initially recorded at fair value, which includes estimated future credit losses expected to be incurred over the life of the loan. Accordingly, the historical allowance for credit losses is not carried over. A nonaccretable difference is established for PCI loans to absorb losses expected on those loans at the date of acquisition. Amounts absorbed by the nonaccretable difference do not affect the income statement or the allowance for credit losses. PCI loans were less than 1 percent of total loans at December 31, 2018 and 2017 . Nonaccrual and Past Due Loans We generally place loans on nonaccrual status when: • the full and timely collection of interest or principal becomes uncertain (generally based on an assessment of the borrower’s financial condition and the adequacy of collateral, if any), such as in bankruptcy or other circumstances; • they are 90 days ( 120 days with respect to real estate 1-4 family first and junior lien mortgages) past due for interest or principal, unless both well-secured and in the process of collection; • part of the principal balance has been charged off; or • for junior lien mortgages, we have evidence that the related first lien mortgage may be 120 days past due or in the process of foreclosure regardless of the junior lien delinquency status. PCI loans are written down at acquisition to fair value using an estimate of cash flows deemed to be collectible and an accretable yield is established. Accordingly, such loans are not classified as nonaccrual because they continue to earn interest from accretable yield, independent of performance in accordance of their contractual terms, and we expect to fully collect the new carrying values of such loans (that is, the new cost basis arising out of purchase accounting). When we place a loan on nonaccrual status, we reverse the accrued unpaid interest receivable against interest income and suspend amortization of any net deferred fees. If the ultimate collectability of the recorded loan balance is in doubt on a nonaccrual loan, the cost recovery method is used and cash collected is applied to first reduce the carrying value of the loan. Otherwise, interest income may be recognized to the extent cash is received. Generally, we return a loan to accrual status when all delinquent interest and principal become current under the terms of the loan agreement and collectability of remaining principal and interest is no longer doubtful. We typically re-underwrite modified loans at the time of a restructuring to determine if there is sufficient evidence of sustained repayment capacity based on the borrower’s financial strength, including documented income, debt to income ratios and other factors. If the borrower has demonstrated performance under the previous terms and the underwriting process shows the capacity to continue to perform under the restructured terms, the loan will generally remain in accruing status. When a loan classified as a troubled debt restructuring (TDR) performs in accordance with its modified terms, the loan either continues to accrue interest (for performing loans) or will return to accrual status after the borrower demonstrates a sustained period of performance (generally six consecutive months of payments, or equivalent, inclusive of consecutive payments made prior to the modification). Loans will be placed on nonaccrual status and a corresponding charge-off is recorded if we believe it is probable that principal and interest contractually due under the modified terms of the agreement will not be collectible. Our loans are considered past due when contractually required principal or interest payments have not been made on the due dates. Loan Charge-off Policies For commercial loans, we generally fully charge off or charge down to net realizable value (fair value of collateral, less estimated costs to sell) for loans secured by collateral when: • management judges the loan to be uncollectible; • repayment is deemed to be protracted beyond reasonable time frames; • the loan has been classified as a loss by either our internal loan review process or our banking regulatory agencies; • the customer has filed bankruptcy and the loss becomes evident owing to a lack of assets; or • the loan is 180 days past due unless both well-secured and in the process of collection. For consumer loans, we fully charge off or charge down to net realizable value when deemed uncollectible due to bankruptcy or other factors, or no later than when the loan is 180 days past due. Impaired Loans We consider a loan to be impaired when, based on current information and events, we determine that we will not be able to collect all amounts due according to the loan contract, including scheduled interest payments. This evaluation is generally based on delinquency information, an assessment of the borrower’s financial condition and the adequacy of collateral, if any. Our impaired loans predominantly include loans on nonaccrual status in the commercial portfolio segment and loans modified in a TDR, whether on accrual or nonaccrual status. When we identify a loan as impaired, we generally measure the impairment, if any, based on the difference between the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount) and the present value of expected future cash flows, discounted at the loan’s effective interest rate. When the value of an impaired loan is calculated by discounting expected cash flows, interest income is recognized using the loan’s effective interest rate over the remaining life of the loan. When collateral is the sole source of repayment for the impaired loan, rather than the borrower’s income or other sources of repayment, we charge down to net realizable value. Troubled Debt Restructurings In situations where, for economic or legal reasons related to a borrower’s financial difficulties, we grant a concession for other than an insignificant period of time to the borrower that we would not otherwise consider, the related loan is classified as a TDR. These modified terms may include rate reductions, principal forgiveness, term extensions, payment forbearance and other actions intended to minimize our economic loss and to avoid foreclosure or repossession of the collateral, if applicable. For modifications where we forgive principal, the entire amount of such principal forgiveness is immediately charged off. Loans classified as TDRs, including loans in trial payment periods (trial modifications), are considered impaired loans. Other than resolutions such as foreclosures and sales, we may remove loans held for investment from TDR classification, but only if they have been refinanced or restructured at market terms and qualify as a new loan. Foreclosed Assets Foreclosed assets obtained through our lending activities primarily include real estate. Generally, loans have been written down to their net realizable value prior to foreclosure. Any further reduction to their net realizable value is recorded with a charge to the allowance for credit losses at foreclosure. We allow up to 90 days after foreclosure to finalize determination of net realizable value. Thereafter, changes in net realizable value are recorded to foreclosed assets expense. The net realizable value of these assets is reviewed and updated periodically depending on the type of property. Allowance for Credit Losses (ACL) The ACL is management’s estimate of credit losses inherent in the loan portfolio, including unfunded credit commitments, at the balance sheet date. We have an established process to determine the appropriateness of the ACL that assesses the losses inherent in our portfolio and related unfunded credit commitments. While we attribute portions of the allowance to our respective commercial and consumer portfolio segments, the entire allowance is available to absorb credit losses inherent in the total loan portfolio and unfunded credit commitments. We develop and document our allowance methodology at the portfolio segment level - commercial loan portfolio and consumer loan portfolio. Our process involves procedures to appropriately consider the unique risk characteristics of our commercial and consumer loan portfolio segments. For each portfolio segment, losses are estimated collectively for groups of loans with similar characteristics, individually or pooled for impaired loans or, for PCI loans, based on the changes in cash flows expected to be collected. Our allowance levels are influenced by loan volumes, loan grade migration or delinquency status, historic loss experience and other conditions influencing loss expectations, such as economic conditions. COMMERCIAL PORTFOLIO SEGMENT ACL METHODOLOGY Generally, commercial loans are assessed for estimated losses by grading each loan using various risk factors as identified through periodic reviews. Our estimation approach for the commercial portfolio reflects the estimated probability of default in accordance with the borrower’s financial strength, and the severity of loss in the event of default, considering the quality of any underlying collateral. Probability of default and severity at the time of default are statistically derived through historical observations of default and losses after default within each credit risk rating. These estimates are adjusted as appropriate based on additional analysis of long-term average loss experience compared to previously forecasted losses, external loss data or other risks identified from current economic conditions and credit quality trends. The estimated probability of default and severity at the time of default are applied to loan equivalent exposures to estimate losses for unfunded credit commitments. The allowance also includes an amount for the estimated impairment on nonaccrual commercial loans and commercial loans modified in a TDR, whether on accrual or nonaccrual status. CONSUMER PORTFOLIO SEGMENT ACL METHODOLOGY For consumer loans that are not identified as a TDR, we generally determine the allowance on a collective basis utilizing forecasted losses to represent our best estimate of inherent loss. We pool loans, generally by product types with similar risk characteristics, such as residential real estate mortgages. As appropriate and to achieve greater accuracy, we may further stratify selected portfolios by sub-product, origination channel, vintage, loss type, geographic location and other predictive characteristics. Models designed for each pool are utilized to develop the loss estimates. We use assumptions for these pools in our forecast models, such as historic delinquency and default, loss severity, home price trends, unemployment trends, and other key economic variables that may influence the frequency and severity of losses in the pool. In determining the appropriate allowance attributable to our residential mortgage portfolio, we take into consideration portfolios determined to be at elevated risk, such as junior lien mortgages behind delinquent first lien mortgages. We incorporate the default rates and severity of loss for these higher risk portfolios, including the impact of our established loan modification programs. Accordingly, the loss content associated with the effects of loan modifications and higher risk portfolios has been captured in our ACL methodology. We separately estimate impairment for consumer loans that have been modified in a TDR (including trial modifications), whether on accrual or nonaccrual status. OTHER ACL MATTERS The allowance for credit losses for both portfolio segments includes an amount for imprecision or uncertainty that may change from period to period. This amount represents management’s judgment of risks inherent in the processes and assumptions used in establishing the allowance. This imprecision considers economic environmental factors, modeling assumptions and performance, process risk, and other subjective factors, including industry trends and emerging risk assessments.
Fair Values of Financial Instruments	Fair Value of Financial Instruments We use fair value measurements in our fair value disclosures and to record certain assets and liabilities at fair value. We base our fair values on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. These fair value measurements are based on the exit price notion and are determined by maximizing the use of observable inputs. However, for certain instruments, we must utilize unobservable inputs in determining fair value due to the lack of observable inputs in the market, which requires greater judgment in the measurement of fair value .
Income Taxes	Income Taxes We are taxed as a REIT under relevant sections of the Internal Revenue Code of 1986 (the Code). A REIT is generally not subject to federal income tax to the extent it complies with the relevant provisions of the Code, including distributing substantially all of its taxable earnings to shareholders, and as long as certain asset, income and stock ownership tests are met. For the tax years ended December 31, 2018 , 2017 , and 2016 , we complied with these provisions and are not subject to federal income tax. As a REIT, dividends paid on preferred and common shares generally constitute ordinary income to the shareholder. However, distributions paid on common shares in excess of REIT taxable income, computed without regard to the dividends paid deduction, do not qualify as dividend income, and instead constitute a return of capital. In the event we do not continue to qualify as a REIT, earnings and cash provided by operating activities available for distribution to shareholders would be reduced by the amount of any applicable income tax obligation. The preferred and common dividends we pay as a REIT are ordinary investment income not eligible for the dividends received deduction for corporate shareholders or for the favorable qualified dividend tax rate applicable to non-corporate taxpayers, however beginning in 2018 non-corporate shareholders may be able to deduct 20% of the preferred and common dividends as a deduction for qualified business income under the Tax Cuts & Jobs Act enacted December 22, 2017. If we were not a REIT, preferred and common dividends we pay generally would qualify for the dividends received deduction for corporate shareholders and the favorable qualified dividend tax rate applicable to non-corporate taxpayers. We file a separate federal income tax return and therefore are not included in the Wells Fargo consolidated tax returns or subject to the allocation of federal income tax liability (benefit) resulting from these consolidated tax returns. In addition, we will file unitary state income tax returns along with other subsidiaries of Wells Fargo. We evaluate uncertain tax positions in accordance with FASB ASC 740, Income Taxes . Based upon our current evaluation, we have concluded that there are no significant uncertain tax positions relevant to the jurisdictions where we are required to file income tax returns requiring recognition in the financial statements at December 31, 2018 , 2017 , and 2016 . We are not subject to federal income tax examinations for tax years prior to 2015 or, with few exceptions, state examinations prior to 2011.
Earnings Per Common Share	Earnings Per Common Share We compute basic earnings per share by dividing income available to common stockholders by the weighted average number of shares of common stock outstanding for the period. We compute diluted earnings per share by dividing income available to common stockholders by the sum of the weighted average number of shares adjusted to include the effect of potentially dilutive shares. Income available to common stockholders is computed as net income less dividends on preferred stock. There were no potentially dilutive shares in any period presented and accordingly, basic and diluted earnings per share are the same.
Retained Earnings (Deficit)	Retained Earnings (Deficit) We expect to distribute annually an aggregate amount of dividends with respect to outstanding capital stock equal to approximately 100 percent of our REIT taxable income for federal income tax purposes. Because our net income determined under GAAP may vary from the determination of REIT taxable income, periodic distributions may exceed our GAAP net income. The retained deficit included within our balance sheet results from cumulative distributions that have exceeded GAAP net income, predominantly due to the impact on REIT taxable income of purchase accounting adjustments attributable to the Company during the years 2009 through 2013, from the 2008 acquisition of Wachovia Corporation by Wells Fargo. The remaining purchase accounting adjustments at December 31, 2018 and 2017 , are not significant.
Subsequent Events	Subsequent Events We have evaluated the effects of events that have occurred subsequent to December 31, 2018 , and there have been no material events that would require recognition in our 2018 financial statements or disclosure in the Notes to the financial statements.
Accounting Standards with Retrospective Application [Policy Text Block]	Accounting Standards Adopted in 2018 In 2018 , we adopted the following new accounting guidance: • Accounting Standards Update (ASU or Update) 2016-15 – Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments; • ASU 2016-01 – Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities; and • ASU 2014-09 – Revenue from Contracts With Customers (Topic 606) and subsequent related Updates. ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice for reporting in the statement of cash flows. We adopted this change in first quarter 2018. The Update did not have any impact on our financial statements. ASU 2016-01 changes the accounting for certain equity securities to record at fair value with unrealized gains or losses reflected in earnings, as well as improve the disclosures of equity securities and the fair value of financial instruments. We do not have equity securities. Accordingly, the impact to our financial statements is limited to our disclosure of the fair value of financial instruments. The valuation methodologies for estimating the fair value of financial instruments that are recorded at amortized cost, including loans, has been changed to conform with an exit price notion. ASU 2014-09 modifies the guidance used to recognize revenue from contracts with customers for transfers of goods or services and transfers of nonfinancial assets, unless those contracts are within the scope of other guidance. Our revenue is from net interest income on financial assets and pledge fees, which are both excluded from the scope of the guidance. Accordingly, there is no impact on our financial statements.

Loans by Loan to Value Ratio, Consumer	The following table shows the most updated LTV and CLTV distribution of the real estate 1-4 family first and junior lien mortgage loan portfolios. We consider the trends in residential real estate markets as we monitor credit risk and establish our allowance for credit losses. In the event of a default, any loss should be limited to the portion of the loan amount in excess of the net realizable value of the underlying real estate collateral value. Certain loans do not have an LTV or CLTV due to industry data availability and portfolios acquired from or serviced by other institutions.

Impaired Loans	The table below summarizes key information for impaired loans. Our impaired loans predominantly include loans on nonaccrual status in the commercial portfolio segment and loans modified in a TDR, whether on accrual or nonaccrual status. These impaired loans generally have estimated losses which are included in the allowance for credit losses. We have impaired loans with no allowance for credit losses when loss content has been previously recognized through charge-offs and we do not anticipate additional charge-offs or losses, or certain loans are currently performing in accordance with their terms and for which no loss has been estimated. Impaired loans exclude PCI loans. The table below includes trial modifications that totaled $5.3 million at December 31, 2018 , and $7.5 million at December 31, 2017 .

TDRs may have multiple types of concessions, but are presented only once in the first modification type based on the order presented in the table above. The reported amounts include loans remodified of $11.4 million , $8.5 million , and $8.8 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. (2) Principal modifications include principal forgiveness at the time of the modification, contingent principal forgiveness granted over the life of the loan based on borrower performance, and principal that has been legally separated and deferred to the end of the loan, with a zero percent contractual interest rate. (3) Other concessions include loans discharged in bankruptcy, loan renewals, term extensions and other interest and noninterest adjustments, but exclude modifications that also forgive principal and/or reduce the contractual interest rate. (4) Charge-offs include write-downs of the investment in the loan in the period it is contractually modified. The amount of charge-off will differ from the modification terms if the loan has been charged down prior to the modification based on our policies. In addition, there may be cases where we have a charge-off/down with no legal principal modification. Modifications resulted in legally forgiving principal (actual, contingent or deferred) of $649 thousand , $1.0 million and $1.2 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. (5) Reflects the effect of reduced interest rates on loans with an interest rate concession as one of their concession types, which includes loans reported as a principal primary modification type that also have an interest rate concession. (6) Trial modifications are granted a delay in payments due under the original terms during the trial payment period. However, these loans continue to advance through delinquency status and accrue interest according to their original terms. Any subsequent permanent modification generally includes interest rate related concessions; however, the exact concession type and resulting financial effect are usually not known until the loan is permanently modified. Trial modifications for the period are presented net of previously reported trial modifications that became permanent in the current period.

Fair Value, Estimated for Financial Instruments Not Carried at Fair Value	The table below is a summary of fair value estimates by level for financial instruments. In connection with the adoption of ASU 2016-01 in first quarter 2018, the valuation methodologies for estimating the fair value of financial instruments that are recorded at amortized cost, including loans, has been changed, where necessary, to conform with an exit price notion. Under an exit price notion, fair value estimates are based upon the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the balance sheet date. For certain loans the estimated fair values prior to adoption of ASU 2016-01 followed an entrance price notion that based fair values on recent prices offered to customers for loans with similar characteristics. The carrying amounts in the following table are recorded in the balance sheet under the indicated captions. We have not included assets and liabilities that are not financial instruments in our disclosure, such as other assets and other liabilities. The total of the fair value calculations presented does not represent, and should not be construed to represent, the underlying value of the Company.
