Organization and Summary of Significant Accounting Policies
Organization	(a) Organization Willis Lease Finance Corporation with its subsidiaries is a provider of aviation services whose primary focus is providing operating leases of commercial aircraft, aircraft engines and other aircraft-related equipment to air carriers, manufacturers and overhaul/repair facilities worldwide. The Company also engages in the selective purchase and resale of commercial aircraft engines. Willis Aeronautical Services, Inc. (“Willis Aero”) is a wholly-owned subsidiary whose primary focus is the sale of aircraft engine parts and materials through the acquisition or consignment of aircraft and engines. In 2016, the Company purchased, through a wholly owned subsidiary Willis Asset Management Limited (“Willis Asset Management”), the business and assets of Total Engine Support Limited (“TES”). TES had been the engine management and consulting business of the TES Aviation Group. Willis Engine Securitization Trust II (“WEST II” or the “WEST II Notes”) is a bankruptcy remote special purpose vehicle which was established for the purpose of financing aircraft engines through an asset-backed securitization (“ABS”). WEST II is a variable interest entity (“VIE”) which the Company owns 100% of the equity and consolidates in its financial statements. On August 4, 2017, the Company closed an asset-backed securitization through a newly-created, bankruptcy-remote, Delaware statutory trust, Willis Engine Structured Trust III (“WEST III” or the “WEST III Notes”), of which the Company is the sole beneficiary. The WEST III Notes were issued in two series, with the Series A Notes issued in an aggregate principal amount of $293.7 million and the Series B Notes in an aggregate principal amount of $42.0 million. The Company used these funds, net of transaction expenses, to pay off part of its revolving credit facility totaling $491.0 million. WEST III is a VIE which the Company owns 100% of the equity and consolidates in its financial statements. The assets and liabilities of WEST III remain on the Company’s balance sheet. A portfolio of commercial jet aircraft engines and leases thereon secures the obligations of WEST III under the ABS. The WEST III Notes have a scheduled amortization and are payable solely from revenue received by WEST III from the engines and the engine leases, after payment of certain expenses of WEST III. Series A Notes bear interest at a fixed rate of 4.69% per annum and Series B Notes bear interest at a fixed rate of 6.36% per annum. The WEST III Notes may be accelerated upon the occurrence of certain events, including the failure to pay interest for five business days after the due date thereof. The WEST III Notes are expected to be paid in 10 years. The legal final maturity of the Notes is August 15, 2042. In connection with the WEST III transactions, the Company entered into a Servicing Agreement and Administrative Agency Agreement with WEST III to provide certain engine, lease management and reporting functions for WEST III in return for fees based on a percentage of collected lease revenues and asset sales. Because WEST III is consolidated for financial statement reporting purposes, all fees eliminate upon consolidation. On August 22, 2018, Willis Engine Structured Trust IV (“WEST IV”), a consolidated VIE of the Company closed its offering of $373.4 million in aggregate principal amount of fixed rate notes (the “WEST IV Notes”). The WEST IV Notes were issued in two series, with the Series A Notes issued in an aggregate principal amount of $326.8 million and the Series B Notes in an aggregate principal amount of $46.7 million. The WEST IV Notes are secured by, among other things, WEST IV’s direct and indirect interests in a portfolio of assets. The Series A Notes have a fixed coupon of 4.75%, an expected maturity of approximately eight years and a final maturity date of September 15, 2043. The Series B Notes have a fixed coupon of 5.44%, an expected maturity of approximately eight years and a final maturity date of September 15, 2043. The Series A Notes were issued at a price of 99.99504% of par and the Series B Notes were issued at a price of 99.99853% of par. Principal and interest on the WEST IV Notes are payable monthly to the extent of available cash in accordance with a priority of payments included in the Indenture. Proceeds from asset sales by WEST IV will be used, at WEST IV’s election subject to certain conditions, to reduce WEST IV’s debt or to acquire other engines or airframes. The assets of WEST II, WEST III and WEST IV are not available to satisfy the Company’s obligations other than the obligations specific to the respective ABS. WEST II, WEST III and WEST IV are consolidated for financial statement presentation purposes. The ABSs’ ability to make distributions and pay dividends to the Company is subject to the prior payments of its debt and other obligations and maintenance of adequate reserves and capital. Under each ABS, cash is collected in a restricted account, which is used to service the debt and any remaining amounts, after debt service and defined expenses, are distributed to the Company. Additionally, a portion of the maintenance reserve payments and lease security deposits are formulaically accumulated in restricted accounts and are available to fund future maintenance events and to secure lease payments, respectively.
Basis of Presentation and Principles of Consolidation	(b) Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the accounts of Willis Lease Finance Corporation and its wholly owned subsidiaries, including VIEs where the Company is the primary beneficiary in accordance with consolidation guidance. The Company evaluates all entities in which it has an economic interest firstly to determine whether for accounting purposes the entity is a variable interest entity or voting interest entity. If the entity is a variable interest entity the Company consolidates the financial statements of that entity if it is the primary beneficiary of the entities’ activities. If the entity is a voting interest entity the Company consolidates the entity when it has a majority of voting interests. Intercompany transactions and balances have been eliminated in consolidation. The condensed parent company financial statements should be read in conjunction with the Company’s consolidated financial statements and the accompanying notes herein.
Revenue Recognition	(c) Revenue Recognition Leasing revenue Revenue from leasing of engines, aircraft and related parts and equipment is recognized as operating lease revenue on a straight-line basis over the terms of the applicable lease agreements. Revenue is not recognized when cash collection is not reasonably assured. When collectability is not reasonably assured, the customer is placed on non-accrual status and revenue is recognized when cash payments are received. Under the terms of some of the Company’s leases, the lessees pay use fees (also known as maintenance reserves) to the Company based on usage of the leased asset, which are designed to cover expected future maintenance costs. Some of these amounts are reimbursable to the lessee if they make specifically defined maintenance expenditures. Use fees received are recognized in revenue as maintenance reserve revenue if they are not reimbursable to the lessee. Use fees that are reimbursable are recorded as a maintenance reserve liability until they are reimbursed to the lessee, the lease terminates, or the obligation to reimburse the lessee for such reserves ceases to exist, at which time they are recognized in revenue as maintenance reserve revenue. Certain lessees may be significantly delinquent in their rental payments and may default on their lease obligations. As of December 31, 2018, the Company had an aggregate of approximately $4.8 million in lease rent and $5.6 million in maintenance reserve receivables more than 30 days past due. Inability to collect receivables or to repossess engines or other leased equipment in the event of a default by a lessee could have a material adverse effect on the Company. The Company estimates an allowance for doubtful accounts for receivables it does not consider fully collectible. The allowance for doubtful accounts includes the following: (1) specific reserves for receivables which are impaired for which management believes full collection is doubtful; and (2) a general reserve for estimated losses based on historical experience. No customer accounted for greater than 10% of total lease rent revenue in 2018, 2017 and 2016. Gain on sale of leased equipment The Company regularly sells equipment from its lease portfolio. This equipment may or may not be subject to a lease at the time of sale. The net gain or loss on such sales is recognized as revenue and consists of proceeds associated with the sale less the net book value of the asset sold and any direct costs associated with the sale. To the extent that deposits associated with the equipment are not included in the sale, any such amount is included in the calculation of gain or loss. Spare parts sales The Spare Parts Sales reportable segment primarily engages in the sale of aircraft engine parts and materials through the acquisition or consignment of engines from third parties or the Company’s leasing operations. The parts are sold at a fixed price with no right of return. In determining the performance obligation, management has identified the promise in the contract to be the shipment of the spare parts to the customer. Title passes to the buyer when the goods are shipped, and the buyer is responsible for any loss in transit, and the Company has a legal right to payment for the spare parts. Management has determined that physical acceptance of the spare parts to be a formality in accordance with Accounting Standards Codification (“ASC”) 606-10-5-86. The spare parts transaction price is a fixed dollar amount and is stated on each purchase order for a fixed amount by total number of parts. Spare parts revenue is based on a set price for a set number of parts as defined in the purchase order. The performance obligation is completed once the parts have shipped and, as a result, all of the transaction price is allocated to that performance obligation. Management has determined that it is appropriate for the Company to recognize spare parts sales at a point in time (i.e., the date the parts are shipped) under ASC 606. Additionally, there is no impact to the timing and amounts of revenue recognized for spare parts sales related to the implementation of ASC 606. Equipment Sales Equipment sales represent the selective purchase and resale of commercial aircraft engines and other aircraft equipment. The Company and customer enter into an agreement which outlines the place and date of sale, purchase price, payment terms, condition of the asset, bill of sale, and the assignment of rights and warranties from the Company to the customer. Management has identified the promise in the equipment sale contract to be the transfer of ownership of the asset. Management believes the asset holds standalone value to the customer as it is not dependent on any other services for functionality purposes and therefore is distinct within the context of the contract and as described in ASC 606-10. As such, management has identified the transfer of the asset as the performance obligation. The transaction price is set at a fixed dollar amount per fixed quantity (number of assets) and is explicitly stated in each contract. Equipment sales revenue is based on a set price for a set number of assets, which is allocated to the performance obligation discussed above, in its entirety. The Company has determined the date of transfer to the customer to be the date the customer obtains control and title over the asset and the date which revenue is to be recognized and payment is due. As such, there is no impact to the timing and amounts of revenue recognized for equipment sales related to the implementation of ASC 606. Managed Services Managed services revenue predominantly represents fleet management and engine storage services which may be combined on a single contract with a customer. Fleet management services are performed for a stated fixed fee as agreed upon in the services agreement. Engine storage services are for a fixed monthly fee. For a contract containing more than one performance obligation, the allocation of the transaction price is generally performed on the basis of the relative stand-alone selling price of each distinct good or service in the contract. As each of the services provided within the contract have separate prices, the Company allocates the price to its related performance obligation described above. Management has determined each of the revenue elements contain performance obligations that are satisfied over time and therefore recognizes revenue over time in accordance with ASC 606-10-25-27. The Company utilizes the percentage-of-completion method (input method) for recognizing fleet management services and will calculate revenues based on labor hours incurred. Additionally, as is required by ASC 606-10-25-35, as circumstances change over time, the Company will update its measure of progress to reflect any changes in the outcome of the performance obligation. Engine storage services are recognized on a monthly basis utilizing the input method of days passed. Therefore, there is no impact to the timing and amounts of revenue recognized for managed services related to the implementation of ASC 606. Amounts owed for managed services are typically billed upon contract completion. At January 1, 2018, $0.4 million of unbilled revenue associated with outstanding contracts was reported in Other assets, all of which was recognized by December 31, 2018. At December 31, 2018, unbilled revenue was $0.6 million and the Company expects it to be fully recognized by June 30, 2019. Additionally, manages services are presented within the Other revenue line in the Consolidated Statements of Income. Other Revenue Other revenue consists primarily of management fee income, lease administration fees, third party consignment commissions earned, service fee revenue, and other discrete revenue items. During the year ended December 31, 2017, other revenue included a net gain on an insurance settlement of $1.3 million related to a leased aircraft.
Equipment Held for Operating Lease	(d) Equipment Held for Operating Lease Aircraft assets held for operating lease are stated at cost, less accumulated depreciation. Certain costs incurred in connection with the acquisition of aircraft assets are capitalized as part of the cost of such assets. Major overhauls paid for by the Company, which improve functionality or extend the original useful life, are capitalized and depreciated over the shorter of the estimated period to the next overhaul (“deferral method”) or the remaining useful life of the equipment. The Company does not accrue for planned major maintenance. The cost of overhauls of aircraft assets under long term leases, for which the lessee is responsible for maintenance during the period of the lease, are paid for by the lessee or from reimbursable maintenance reserves paid to the Company in accordance with the lease, and are not capitalized. Based on specific aspects of the equipment, the Company generally depreciates engines on a straight-line basis over a 15-year period from the acquisition date to a 55% residual value. This methodology is believed to accurately reflect the Company’s typical holding period for the engine assets and, that the residual value assumption reasonably approximates the selling price of the assets 15 years from date of acquisition. The typical 15 year holding period is the estimated useful life of the Company’s engines based on its business model and plans, and represents how long the Company anticipates holding a newly acquired engine. The technical useful life of a new engine can be in excess of 25 years. The Company reviews the useful life and residual values of all engines periodically as demand changes to accurately depreciate the cost of equipment over the useful life of the engines. The aircraft and airframes owned by the Company are depreciated on a straight-line basis over an estimated useful life of 13 to 20 years to a 15% to 17% residual value. The other leased parts and related equipment owned by the Company are depreciated on a straight-line basis over an estimated useful life of 14 to 15 years to a 25% residual value. The useful life of older generation engines and aircraft may be significantly less based upon the technical status of the engine, as well as supply and demand factors. For these older generation engines and aircraft, the remaining useful life and the remaining expected holding period are typically the same. For older generation engines or aircraft that are unlikely to be repaired at the end of the current expected useful lives, the Company depreciates the engines or aircraft over their estimated lives to a residual value based on an estimate of the wholesale value of the parts after disassembly. As of December 31, 2018, 34 engines having a net book value of $46.3 million were depreciated under this policy with estimated useful lives ranging from 1 to 80 months. The Company adjusts its estimates annually for these older generation assets, including updating estimates of an engine’s or aircraft’s remaining operating life as well as future residual value expected from part-out based on the current technical status of the engine or aircraft. The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets to be disposed are reported at the lower of carrying amount or fair value less cost to sell. Impairment is identified by review of appraisals or by comparison of undiscounted forecasted cash flows, including estimated sales proceeds, over the life of the asset with the assets’ book value. If the forecasted undiscounted cash flows are less than the book value, the asset is written down to its fair value. Fair value is determined per individual asset by reference to independent appraisals, quoted market prices (e.g. an offer to purchase) and other factors considered relevant by the Company. The Company conducts a formal annual review of the carrying value of long-lived assets and also evaluates assets during the year if a triggering event is identified indicating impairment is possible. Such annual review resulted in an impairment charge of $5.3 million, $4.4 million and $1.8 million in 2018, 2017, and 2016, respectively (included in “Write-down of equipment” in the Consolidated Statements of Income).
Equipment Held for Sale	(e) Equipment Held for Sale Equipment held for sale includes engines being marketed for sale as well as third party consigned assets. The assets to be disposed are reported at the lower of carrying amount or fair value less costs to sell.
Debt Issuance Costs and Related Fees	(f) Debt Issuance Costs and Related Fees Fees paid in order to secure debt are capitalized, included in Debt obligations on the Consolidated Balance Sheets, and amortized over the life of the related loan using the effective interest method.
Interest Rate Hedging	(g) Interest Rate Hedging The Company enters into various derivative instruments periodically to mitigate the exposure on variable rate borrowings. The derivative instruments are fixed-rate interest swaps that are recorded at fair value as either an asset or liability. While substantially all of the Company’s derivative transactions are entered into for the purposes described above, hedge accounting is only applied where specific criteria have been met and it is practicable to do so. In order to apply hedge accounting, the transaction must be designated as a hedge and it must be highly effective. The hedging instrument’s effectiveness is assessed utilizing regression analysis at the inception of the hedge and on at least a quarterly basis throughout its life. All of the transactions that the Company has designated as hedges are cash flow hedges. The effective portion of the change in fair value on a derivative instrument designated as a cash flow hedge is reported as a component of other comprehensive income and is reclassified into earnings in the period during which the transaction being hedged affects earnings. The ineffective portion of the hedges is recorded in earnings in the current period.
Income Taxes	(h) Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred income taxes are recognized for the tax consequences of “temporary differences” by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The effect on deferred taxes of a change in the tax rates is recognized in income in the period that includes the enactment date. The Company recognizes in the financial statements the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs (see Note 7). The Company files income tax returns in various states and countries which may have different statutes of limitations. The Company records penalties and accrued interest related to uncertain tax positions in income tax expense. Such adjustments have historically been minimal and immaterial to our financial results.
Property, Equipment and Furnishings	(i) Property, Equipment and Furnishings Property, equipment and furnishings are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets, which range from three to thirty-nine years. Leasehold improvements are recorded at cost and depreciated by the straight-line method over the shorter of the lease term or useful life of the leasehold.
Cash and Cash Equivalents	(j) Cash and Cash Equivalents The Company considers highly liquid investments readily convertible into known amounts of cash, with original maturities of 90 days or less, as cash equivalents.
Restricted Cash	(k) Restricted Cash The Company has certain bank accounts that are subject to restrictions in connection with its WEST II, WEST III and WEST IV borrowings. Under these borrowings, cash is collected in restricted accounts, which are used to service the debt and any remaining amounts, after debt service and defined expenses, are distributed to the Company. Additionally, a portion of maintenance reserve payments and some or all of the lease security deposits are accumulated in restricted accounts and are available to fund future maintenance events and to secure lease payments, respectively. Under WEST II, cash from maintenance reserve payments is held in a restricted cash account equal to the maintenance obligations projected for the subsequent six months, and is subject to a minimum balance of $9.0 million. Under WEST III and WEST IV, cash from maintenance reserve payments is held in a restricted cash account equal to a portion of the maintenance obligations projected for the subsequent nine months, and is subject to a minimum balance of $10.0 million. Under WEST II, all security deposits are held in a restricted cash account until the end of the lease. Under WEST III and WEST IV, security deposits are held in a restricted cash account equal to a portion of the security deposits for leases scheduled to terminate over the subsequent four months, subject to a minimum balance of $1.0 million. Provided lease return conditions have been met, these deposits will be returned to the lessee. To the extent return conditions are not met, these deposits may be retained by the Company.
Spare Parts Inventory	(l) Spare Parts Inventory Spare parts inventory consists of spare aircraft and engine parts purchased either directly by Willis Aero and also engines removed from the lease portfolio to be parted out. Spare parts inventory is stated at lower of cost or net realizable value. An impairment charge for excess or inactive inventory is recorded based upon an analysis that considers current inventory levels, historical usage patterns, future sales expectations and salvage value.
Intangible Assets	(m) Intangible Assets Intangible assets include customer relationships and goodwill arising from the Company’s acquisitions of TES. Intangible assets are accounted for in accordance with ASC 350, “Intangibles — Goodwill and Other.” Customer relationships are amortized on a straight line basis over their estimated useful life of five years. The Company has no intangible assets with indefinite useful lives. Goodwill is assessed for impairment annually.
Other assets	(n) Other assets Other assets typically include prepaid purchase deposits and other prepaid expenses. As of December 31, 2018 and 2017, other assets included prepaid deposits of $1.9 million and $36.5 million, respectively, relating to commitments to purchase equipment.
Management Estimates	(o) Management Estimates These financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States. The preparation of consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Management evaluates estimates on an ongoing basis, including those related to residual values, estimated asset lives, impairments and bad debts. Estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Management believes that the accounting policies on revenue recognition, maintenance reserves and expenditures, useful life of equipment, asset residual values, asset impairment and allowance for doubtful accounts are critical to the results of operations. If the useful lives or residual values are lower than those estimated, upon sale of the asset a loss may be realized. Significant management judgment is required in the forecasting of future operating results, which are used in the preparation of projected undiscounted cash-flows and should different conditions prevail, material impairment write-downs may occur.
Earnings per share information	(p) Earnings per share information Basic earnings per common share is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is computed by dividing net income by the weighted average number of shares outstanding, adjusted for the dilutive effect of unvested restricted stock awards (“RSA’s”). See Note 9 for more information on the computation of earnings per share.
Investments	(q) Investments The Company’s investments are joint ventures, where it owns 50% of the equity of the ventures and are accounted for using the equity method of accounting. The investments are recorded at the amount invested plus or minus our 50% share of net income or loss, less any distributions or return of capital received from the entities.
Stock Based Compensation	(r) Stock Based Compensation The Company recognizes stock based compensation expense in the financial statements for share-based awards based on the grant-date fair value of those awards. Stock based compensation expense is recognized over the requisite service periods of the awards on a straight-line basis, which is generally commensurate with the vesting term. Additionally, the Company implemented ASU 2016-09 in the first quarter of 2017, using the modified retrospective approach, and elected to account for forfeitures as they occur. As such, a $1.3 million cumulative effect adjustment was recorded to the opening balance of Retained earnings for the impact in tax benefits as well as the differential between the amount of compensation cost previously recorded and the amount that would have been recorded without assuming forfeitures.
Initial Direct Costs associated with Leases	(s) Initial Direct Costs associated with Leases The Company accounts for the initial direct costs, including sales commissions and legal fees, incurred in obtaining a new lease by deferring and amortizing those costs over the term of the lease. The amortization of these costs is recorded under General and administrative expenses in the Consolidated Statements of Income. The amounts amortized were $1.9 million, $1.8 million and $1.6 million for the years ended December 31, 2018, 2017 and 2016, respectively.
Maintenance Rights	(t) Maintenance Rights The Company identifies, measures and accounts for maintenance right assets and liabilities associated with acquisitions of equipment with in-place leases. A maintenance right asset represents the fair value of the contractual right under a lease to receive equipment in an improved maintenance condition as compared to the maintenance condition on the acquisition date. A maintenance right liability represents the Company's obligation to pay the lessee for the difference between the lease-end contractual maintenance condition of the equipment and the actual maintenance condition of the equipment on the acquisition date. The equipment condition at the end of the lease term may result in either overhaul work being performed by the lessee to meet the required return condition or a financial settlement. When a capital event is performed on the equipment by the lessee, which satisfies their maintenance right obligation, the maintenance rights are added to the equipment basis and depreciated to the next capital event. When equipment is sold before the end of the pre-existing lease, the maintenance rights are applied against any accumulated maintenance reserves, if paid by the lessee, and the remaining balance is applied to the disposition gain or loss. When a lease terminates, an end of lease true-up is performed and the maintenance right is applied against the accumulated maintenance reserves or, for non-reserve lessees the final settlement payment, and any remaining net maintenance right is recorded in the income statement.
Foreign Currency Translation	(u) Foreign Currency Translation The Company’s foreign investments have been converted at rates of exchange in effect at the balance sheet dates. The changes in exchange rates in our foreign investments reported under the equity method are included in stockholders’ equity as accumulated other comprehensive income.
Risk Concentrations	(v) Risk Concentrations Financial instruments which potentially subject us to concentrations of credit risk consist principally of cash deposits, lease receivables and interest rate swaps. The Company places our cash deposits with financial institutions and other creditworthy institutions such as money market funds and limits the amount of credit exposure to any one party. Management opts for security of principal as opposed to yield. Concentrations of credit risk with respect to lease receivables are limited due to the large number of customers comprising the customer base, and their dispersion across different geographic areas. Some lessees are required to make payments for maintenance reserves at the end of the lease however, this risk is considered limited due to the relatively few lessees which have this provision in the lease. The Company enters into interest rate swap agreements with counterparties that are investment grade financial institutions.
Recent Accounting Pronouncements	(w) Recent Accounting Pronouncements Recent Accounting Pronouncements Adopted by the Company In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 amends the accounting guidance on revenue recognition. The amendments in this accounting standard update are intended to provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices, and improve disclosure requirements. Under the new standard, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. The principles in the standard should be applied using a five-step model that includes 1) identifying the contract(s) with a customer, 2) identifying the performance obligations in the contract, 3) determining the transaction price, 4) allocating the transaction price to the performance obligations in the contract, and 5) recognizing revenue when (or as) the performance obligations are satisfied. The standard also requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In addition, the standard amends the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are and are not in a contract with a customer (for example, sales of real estate) to be consistent with the standard’s guidance on recognition and measurement (including the constraint on revenue). The FASB also subsequently issued several amendments to the standard, including clarification on principal versus agent guidance, identifying performance obligations, and immaterial goods and services in a contract. The Company adopted ASU 2014-09 and its related amendments (collectively known as ASC 606) effective on January 1, 2018 using the modified retrospective approach applied only to contracts not completed as of the date of adoption, with no restatement of comparative periods. Therefore, the comparative information has not been adjusted and continues to be reported under ASC Topic 605. Please see Note 1(c) for a discussion of the Company’s updated policies related to revenue recognition and accounting for costs to obtain and fulfill a customer contract and Note 2 "Revenue from Contracts with Customers" for the disclosures related to the impact of adopting this standard. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments” (a consensus of the Emerging Issues Task Force) to improve the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The update provides guidance on specific cash flow classification issues including the following: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (3) contingent consideration payments made after a business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions; and (8) separately identifiable cash flows and application of the predominance principle. Prior GAAP did not include specific guidance on these eight cash flow classification issues. The Company adopted the guidance effective January 1, 2018 and utilizing the cumulative earnings approach on a retrospective basis, reclassified $1.9 million and $1.2 million of distributions from joint ventures during 2017 and 2016, respectively, from cash flows from investing activities to cash flows from operating activities. The remaining provisions of this update did not have a material impact on the Company’s consolidated statements of cash flows. In January 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” (“ASU 2017-04”) that eliminates “Step 2” from the goodwill impairment test. The Company made the election to early adopt ASU 2017-04 as of January 1, 2018 and the standard was applied on a prospective basis, as required. The adoption of this standard did not have an impact on the consolidated financial statements or the related disclosures. In February 2017, the FASB issued ASU 2017-05, “Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets”. The FASB issued this ASU to clarify the scope of subtopic 610-20, which was issued in May 2014 as part of ASU 2014-09. The effective date and transition requirements of these amendments are the same as the effective date and transition requirements of ASU 2014-09. On January 1, 2018 the Company adopted this standard utilizing the modified retrospective approach and the practical expedient under ASC 606-10-65-1 which allowed the Company the election to not apply the guidance to completed contracts. As there were no incomplete contracts as of January 1, 2018, the Company did not have a cumulative effect adjustment to retained earnings upon adoption. In May 2017, the FASB issued ASU 2017-09, “Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting,” that provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The new guidance became effective for the Company on January 1, 2018 and was applied on a prospective basis, as required. The adoption of this standard did not have an impact on the consolidated financial statements or the related disclosures. In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”) to address stakeholder concerns about the guidance in current GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “2017 Act”). The ASU must be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the 2017 Act is recognized. The Company made the election to early adopt ASU 2018-02 as of January 1, 2018 (the period of adoption) and recorded a reclassification of $59 thousand between Other comprehensive income and Retained earnings as of January 1, 2018. In September 2018, the FASB issued ASU 2018-15, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” (“ASU 2018-15”) which requires cloud computing arrangements in a service contact to follow the internal-use software guidance provided by ASC 350-40 in determining the accounting treatment of implementation costs. ASC 350-40 states that only qualifying costs incurred during the application development stage may be capitalized. The Company made the election to early adopt ASU 2018-15 on a retrospective basis, and during 2018 has capitalized $0.9 million in cloud computing arrangement implementation costs which is presented within Other assets. There was no prior period impact related to the adoption of ASU 2018-15. Recent Accounting Pronouncements To Be Adopted by the Company In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). The ASU is targeted at simplifying the application of hedge accounting and aims at aligning the recognition and presentation of the effects of hedge instruments and hedge items. ASU 2017-12 is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company plans to adopt this guidance effective January 1, 2019 and is currently evaluating the potential impact adoption will have on the consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 revises the measurement of credit losses for financial assets measured at amortized cost from an incurred loss methodology to an expected loss methodology. ASU 2016-13 affects trade receivables, debt securities, net investment in leases, and most other financial assets that represent a right to receive cash. Additional disclosures about significant estimates and credit quality are also required. In November 2018, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses”. This ASU clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. The effective date will be the first quarter of fiscal year 2021, with early adoption permitted beginning in fiscal year 2020. The Company is evaluating the potential effects on the consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASC 842”) that amends the accounting guidance on leases for both lessees and lessors. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The FASB also subsequently issued amendments to the standard, including providing an additional and optional transition method to adopt the new standard, described below, as well as certain practical expedients related to land easements and lessor accounting. The amendments in this accounting standard update are effective for the Company on January 1, 2019, with early adoption permitted. The Company will adopt this accounting standard update effective January 1, 2019. The accounting standard update originally required the use of a modified retrospective approach reflecting the application of the standard to leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements with the option to elect certain practical expedients. A subsequent amendment to the standard provides an additional and optional transition method that allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard will continue to be in accordance with ASC Topic 840 if the optional transition method is elected. The Company plans to adopt the standard using the optional transition method with no restatement of comparative periods and a cumulative effect adjustment, if any, recognized as of the date of adoption. The Company does not expect that this standard to have a material effect on its financial statements due to the recognition of new ROU assets and lease liabilities for lessee activities. Additionally, while the Company continues to evaluate certain aspects of the new standard in its lessor capacity, including those still being revised by the FASB, the Company does not expect the new standard will have a material effect on its financial statements and also does not expect a significant change in its leasing activities between now and adoption. As part of the implementation process, the Company assessed its lease arrangements and evaluated practical expedient and accounting policy elections to meet the reporting requirements of this standard. The Company has also evaluated the changes in controls and processes that are necessary to implement the new standard, and no material changes were required. The new standard provides a number of optional practical expedients in transition. The Company expects to elect the ‘package of practical expedients’ which permits us not to reassess under the new standard the prior conclusions about lease identification, lease classification, and initial direct costs. The Company does not expect to elect the use-of-hindsight or the practical expedient pertaining to land easements; the latter not being applicable to WLFC. Consequently, on adoption, the Company expects to recognize additional operating liabilities ranging from $4.0 million to $5.0 million, with corresponding ROU assets of approximately the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. Under ASC 842, a lease is a sales-type lease if any one of five criteria are met, each of which indicate that the lease, in effect, transfers control of the underlying asset to the lessee. If none of those five criteria are met, but two additional criteria are both met, indicating that the lessor has transferred substantially all the risks and benefits of the underlying asset to the lessee and a third party, the lease is a direct financing lease. All leases that are not sales-type or direct financing leases are operating leases. As lessor, the Company believes substantially all of its leases will continue to be classified as operating leases under the new standard. In addition, due to the new standard’s narrowed definition of initial direct costs, the Company expects to expense as incurred certain lease origination costs currently capitalized as initial direct costs and amortized to expense over the lease term. The new standard also provides practical expedients for an entity’s ongoing accounting. The Company currently expects to elect the short-term lease recognition exemption for all leases that qualify. As a result, for those leases that qualify, the Company will not recognize ROU assets or lease liabilities, including for existing short-term leases of those assets in transition. The Company also currently expects to elect the practical expedient to not separate lease and non-lease components for the majority of its leases as both lessee and lessor. The Company also expects significant new disclosures about its leasing activities in accordance with the new standard.
