AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

June 30, 2018

(Unaudited)

1.  Summary of Significant Accounting Policies

The significant accounting policies of Willis Lease Finance Corporation and its subsidiaries (collectively, the “Company”) were described in Note 1 to the audited consolidated financial statements included in the Company’s 2017 Annual Report on Form 10-K (“2017 Form 10-K”). There have been no significant changes in the Company’s significant accounting policies for the six months ended June 30, 2018.

(a)    Basis of Presentation

The accompanying Unaudited Condensed Consolidated Financial Statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission. Therefore, they do not include all information and footnotes normally included in annual consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the 2017 Form 10-K. In the opinion of management, the Unaudited Condensed Consolidated Financial Statements contain all adjustments (consisting principally of normal recurring accruals) necessary for a fair presentation of the condensed consolidated balance sheets, statements of income, statements of comprehensive income and statements of cash flows for such interim periods presented. Additionally, operating results for interim periods are not necessarily indicative of the results that can be expected for a full year.

In accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. These estimates and judgments are based on historical experience and other assumptions that management believes are reasonable. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. The significant estimates made in the accompanying Unaudited Condensed Consolidated Financial Statements include certain assumptions related to goodwill, intangible assets, long-lived assets, assets held for sale, estimated income taxes and stock-based compensation. Actual results may differ from these estimates under different assumptions or conditions.

(b)     Reclassifications

In conjunction with our review of the fourth quarter of 2017, the Company reclassified scrap inventory write-offs and inventory lower of cost or market write-downs that were previously presented within Write-down of equipment to the Cost of spare parts and equipment sales line item. The first half of 2017 was impacted by an adjustment of $1.8 million and is reflected as an increase to Cost of spare parts and equipment sales and a decrease to Write-down of equipment. These reclassified items had no effect on the reported results of operations, financial condition or statements of cash flows.

(c)     Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, including variable interest entities (“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 VIE 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.

(d)    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 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 Accounting Standards Codification (“ASC”) 606) effective on January 1, 2018 using the modified retrospective approach applied only to contracts not completed as of the date of adoption. Please see Note 2 "Revenue from Contracts with Customers" for the required disclosures related to the impact of adopting this standard and a discussion of the Company's updated policies related to revenue recognition and accounting for costs to obtain and fulfill a customer contract.

In January 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” that eliminates “Step 2” from the goodwill impairment test. The Company has 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 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” 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 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 Act is recognized. The Company has 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.

Recent Accounting Pronouncements To Be Adopted by the Company

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued ASU 2016-02 to increase transparency and comparability among organizations recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under ASU 2016-02, lessors will account for leases using an approach that is substantially equivalent to existing GAAP for sales-type leases, direct financing leases and operating leases. Unlike current guidance, however, a lease with collectability uncertainties may be classified as a sales-type lease. If collectability of lease payments, plus any amount necessary to

8

satisfy a lessee residual value guarantee, is not probable, lease payments received will be recognized as a deposit liability and the underlying assets will not be derecognized until collectability of the remaining amounts becomes probable. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and must be adopted using a modified retrospective transition. 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.

2. Revenue from Contracts with Customers

As of January 1, 2018, the Company adopted ASU 2014-09 and all subsequent ASUs that modified ASC 606. While only a portion of the Company’s revenues is impacted by this guidance as it does not apply to contracts falling under the leasing standard, as part of the implementation process the Company performed an analysis to identify accounting policies that needed to change and additional disclosures that are  required. The Company considered factors such as customer contracts with unique revenue recognition considerations, the nature and type of goods and services offered, the degree to which contracts include multiple performance obligations or variable consideration, and the pattern in which revenue is currently recognized, among other things. All revenue streams applicable to the new standard (Spare parts and equipment sales and Managed services which is reflected within Other revenue) were evaluated by management. The Company considered recognition under the new standard and concluded the timing of the Company’s revenue recognition will remain the same. 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 following table disaggregates revenue by major source for the three and six months ended June 30, 2018 (in thousands):

(1) Represents revenue generated between our reportable segments.

(2) Leasing revenue is recognized under the lease accounting guidance in ASC 840 Leases, and therefore qualifies for the scope exception under ASC 606.

(3) Gain on sale of leased equipment is accounted for under ASC 610-20,Gains and losses from the derecognition of nonfinancial assets.

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.

9

Use fees that are reimbursable are recorded as a maintenance reserve liability until they are reimbursed to the lessee or the lease terminates, 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 June 30, 2018, the Company had an aggregate of approximately $4.1 million in lease rent and $3.5 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 lease 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.

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 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 engine 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. The parts are sold at a fixed price with no right of return and are shipped “FOB shipping point.” In determining the performance obligation, management has identified the promise in the contract to be the shipment of the spare parts to the customer.When the spare parts are shipped FOB shipping point, 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 ASC 606-10-5-86 and as the Company is not obliged to perform additional services under these arrangements, the shipment of the spare parts is the performance obligation. 

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.  There is one performance obligation identified, as discussed above, which is the shipment of the parts 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., on the shipment date) 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. The result of allocation consideration on this basis is consistent with the overall core principal of ASC 606 (to recognize revenue in an amount that depicts the consideration to which the Company expects to be entitled in exchange for the promised goods or services). As each of the services provided within the contract have separate prices, the Company allocates the stated 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 will continue utilizing 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 will continue to be 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 June 30, 2018. At June 30, 2018, unbilled revenue was $0.7 million and the Company expects it to be fully recognized by December 31, 2018. Additionally, Managed services are presented within the Other revenue line in the condensed consolidated statements of income.

2022		190,889
Thereafter		258,405
Total	$	1,249,476

Virtually all of the above debt requires ongoing compliance with the covenants of each financing, including debt/equity ratios, minimum tangible net worth and minimum interest coverage ratios, and other eligibility criteria including customer and geographic concentration restrictions. The Company also has certain negative financial covenants such as liens, advances, change in business, sales of assets, dividends and stock repurchases. These covenants are tested either monthly or quarterly and the Company was in full compliance with all financial covenant requirements at June 30, 2018.

12

The Company maintains a revolving credit facility to finance the acquisition of aircraft engines for lease as well as for general working capital purposes. The $890 million revolving credit facility has an accordion feature which would expand the entire credit facility up to $1 billion. The interest rate is adjusted quarterly, based on the Company’s leverage ratio, as calculated under the terms of the revolving credit facility.

5.  Derivative Instruments

The Company periodically holds interest rate derivative instruments to mitigate exposure to changes in interest rates, in particular one-month LIBOR, with $666.0 million and $501.3 million of borrowings at June 30, 2018 and December 31, 2017, respectively, at variable rates. As a matter of policy, management does not use derivatives for speculative purposes.  During 2016, the Company entered into one interest rate swap agreement which has a notional outstanding amount of $100.0 million, with a remaining term of 34 months as of June 30, 2018. The fair value of the swap at June 30, 2018 and December 31, 2017 was $2.5 million and $1.1 million, respectively, representing a net asset. The Company recorded a gain of $94 thousand and a loss of $0.2 million in the three months ended June 30, 2018 and 2017, respectively, and a gain of $69 thousand and a loss of $0.4 million during the six months ended June 30, 2018 and 2017, respectively, from derivative instruments.

The Company estimates the fair value of  derivative instruments using a discounted cash flow technique and has used creditworthiness inputs that corroborate observable market data evaluating the Company’s and counterparty’s risk of non-performance. Valuation of the derivative instruments requires certain assumptions for underlying variables and the use of different assumptions would result in a different valuation. Management believes it has applied assumptions consistently during the period. The Company applies hedge accounting and accounts for the change in fair value of its cash flow hedges through other comprehensive income for all derivative instruments.

Effect of Derivative Instruments on Earnings in the Statements of Income and on Comprehensive Income

The following tables provide additional information about the financial statement effects related to the cash flow hedges for the three and six months ended June 30, 2018 and 2017:

	Amount of Gain (Loss) Recognized				Location of (Gain) Loss	Amount of (Gain) Loss Recognized
	in OCI on Derivatives				Reclassified from	from Accumulated OCI into Income

Interest rate contracts	$	1,415	$	(3)	Interest expense	$	(69)	$	400
Total	$	1,415	$	(3)	Total	$	(69)	$	400

The derivatives were designated in a cash flow hedging relationship with the effective portion of the change in fair value of the derivative reported in the cash flow hedges subaccount of accumulated other comprehensive income.

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 or it is probable that the forecasted transaction will not occur. The ineffective portion of the hedges is recorded in earnings in the current period. However, these are highly effective hedges and no significant ineffectiveness occurred in the periods presented.

13

Counterparty Credit Risk

The Company evaluates the creditworthiness of the counterparties under its hedging agreements. The counterparty for the interest rate swap in place during 2018 was a large financial institution in the United States that possessed an investment grade credit rating. Based on this rating, the Company believes that the counterparty was creditworthy and that their continuing performance under the hedging agreement was probable, and did not require the counterparty to provide collateral or other security to the Company.

6.  Income Taxes

Income tax expense for the three and six months ended June 30, 2018 was $3.2 million and $5.8 million, respectively. Income tax expense for the three and six months ended June 30, 2017 was $4.2 million and $10.4 million, respectively. The effective tax rate for the three and six months ended June 30, 2018 was 27.9% and 27.2%, respectively. The effective tax rate for the three and six months ended June 30, 2017 was 41.0% and 42.4%, respectively. The 2018 tax rate reflects the enactment of the Tax Cuts and Jobs Act of 2017 (the “Act”) which made significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017.

The Company records tax expense or benefit for unusual or infrequent items discretely in the period in which they occur. The Company’s tax rate is subject to change based on changes in the mix of assets leased to domestic and foreign lessees, the proportions of revenue generated within and outside of California, the amount of executive compensation exceeding $1.0 million as defined in IRS code 162(m) and numerous other factors, including changes in tax law.

7. Fair Value Measurements

The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation. Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of judgment, and therefore cannot be determined with precision.

Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also establishes the following three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments:

· Cash and cash equivalents, restricted cash, operating lease related receivables, and accounts payable: The amounts reported in the accompanying Consolidated Balance Sheets approximate fair value due to their short-term nature.

· Debt obligations: The carrying amount of the Company’s outstanding balance on its Debt obligations as of June 30, 2018 and December 31, 2017 was estimated to have a fair value of approximately $1,089.5 million and $1,090.0 million, respectively, based on the fair value of estimated future payments calculated using interest rates that approximate prevailing market rates at each period end (Level 2 inputs).

14

Assets Measured and Recorded at Fair Value on a Recurring Basis

As of June 30, 2018 and December 31, 2017, the Company measured the fair value of its interest rate swap of $100.0 million (notional amount) based on Level 2 inputs, due to the usage of inputs that can be corroborated by observable market data. The Company estimates the fair value of derivative instruments using a discounted cash flow technique and has used creditworthiness inputs that corroborate observable market data evaluating the Company’s and counterparties’ risk of non-performance. The interest rate swap agreement had a net fair value of $2.5 million and $1.1 million as of June 30, 2018 and December 31, 2017, respectively.  For the six months ended June 30, 2018, $69 thousand was realized through the income statement as a decrease in interest expense. For the six months ended June 30, 2017, $0.4 million was realized through the income statement as an increase in interest expense.

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company determines fair value of long-lived assets held and used, such as Equipment held for operating lease and Equipment held for sale, by reference to independent appraisals, quoted market prices (e.g. an offer to purchase) and other factors. An impairment charge is recorded when the carrying value of the asset exceeds its fair value. The Company used Level 2 inputs to measure write-downs of equipment held for lease, equipment held for sale and spare parts inventory as of June 30, 2018 and December 31, 2017.

	Assets at Fair Value																Total Losses
	June 30, 2018								December 31, 2017								Six Months Ended June 30,
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total		2018		2017

A write-down of $3.6 million was recorded during the six months ended June 30, 2018 for three engines due to a management decision to part-out the engines, in which the net book values exceeded the estimated proceeds.

A write-down of $13.4 million was recorded during the six months ended June 30, 2017 for four engines and three aircraft for which their leases ended or were modified in the period. Management evaluated the equipment return condition, end of lease compensation, accumulated maintenance reserves and expected future proceeds from part out and sale to record its initial best estimate of impairment. 

8.  Earnings Per Share

Basic earnings per common share is computed by dividing net income, less preferred stock dividends and accretion of preferred stock issuance costs, by the weighted average number of common shares outstanding for the period. Treasury stock is excluded from the weighted average number of shares of common stock outstanding. Diluted earnings per share attributable to common stockholders is computed based on the weighted average number of shares of common stock and dilutive securities outstanding during the period. Dilutive securities are common stock equivalents that are freely exercisable into common stock at less than market prices or otherwise dilute earnings if converted. The net effect of common stock equivalents is based on the incremental common stock that would be issued upon the vesting of restricted stock using the treasury stock method. Common stock equivalents are not included in diluted earnings per share when their inclusion is antidilutive. Additionally, redeemable preferred stock is not convertible and does not affect dilutive shares.

The computations of diluted weighted average earnings per common share do not include approximately 0.3 million and 0.1 million restricted shares for the three and six months ended June 30, 2018, respectively, as the effect of their inclusion would have been antidilutive to earnings per share. There were no anti-dilutive shares during the three months ended June 30, 2017 and 43 thousand anti-dilutive shares excluded from the computation of diluted weighted average earnings per common share during the six months ended June 30, 2017. The difference between average common shares outstanding to calculate basic and assuming full dilution is due to restricted stock issued under the 2007 Stock Incentive Plan.

15

The following table presents the calculation of basic and diluted EPS:

Diluted weighted average earnings per common share	$	1.26	$	0.92	$	2.25	$	2.17

9. Equity

Common Stock Repurchase

In September 2012, the Company announced that its Board of Directors authorized a plan to repurchase up to $100.0 million of its common stock over the next 5 years. The Board of Directors reaffirmed the repurchase plan in October 2016 and extended the plan to December 31, 2018. Repurchased shares are immediately retired. During the six months ended June 30, 2018, the Company repurchased a total of 297,367 shares of common stock for approximately $10.2 million under this program, at a weighted average price of $34.24 per share. At June 30, 2018, approximately $19.2 million is available to purchase shares under the plan.

Redeemable Preferred Stock

Dividends: The Company’s Series A-1 Preferred Stock and Series A-2 Preferred Stock accrue quarterly dividends at the rate per annum of 6.5% per share. During the six months ended June 30, 2018, the Company paid total dividends of $1.6 million on the Series A-1 and Series A-2 Preferred Stock. For additional disclosures on the Company’s Redeemable Preferred Stock, refer to Note 10 in the 2017 Form 10-K.

10.  Stock-Based Compensation Plans

The components of stock-based compensation expense for the three and six months ended June 30, 2018 and 2017 were as follows:

	Three months ended  June 30,				Six months ended June 30,
	2018		2017		2018		2017
	(in thousands)				(in thousands)
2007 Stock Incentive Plan	$	1,660	$	1,194	$	2,565	$	2,059
Employee Stock Purchase Plan		—		6		20		15
Total Stock Compensation Expense	$	1,660	$	1,200	$	2,585	$	2,074

The 2007 Stock Incentive Plan (the “2007 Plan”) was adopted on May 24, 2007. Under this 2007 Plan, a total of 2,800,000 shares are authorized for stock based compensation available in the form of either restricted stock awards (“RSA’s”) or stock options. The RSA’s are subject to service-based vesting, typically between one and four years, where a specific period of continued employment must pass before an award vests. The expense associated with these awards is recognized on a straight-line basis over the respective vesting period, with forfeitures accounted for as they occur. For any vesting tranche of an award, the cumulative amount of compensation cost recognized is equal to the portion of the grant‑date fair value of the award tranche that is actually vested at that date.

As of June 30, 2018, the Company has granted 2,883,414 RSA’s under the 2007 Plan. Of this amount, 166,744 shares were cancelled and returned to the pool of shares which could be granted under the 2007 Plan resulting in a net number of 83,330 shares available for future issuance. The fair value of the restricted stock awards equaled the stock price at the grant date. There are no stock options outstanding under the 2007 Plan.

16

The 2018 Stock Incentive Plan (the “2018 Plan”) was adopted on May 24, 2018. Under this 2018 Plan, a total of 800,000 shares are authorized for stock based compensation, plus the number of shares remaining under the 2007 Plan and any future forfeited awards under the 2007 Plan, in the form of RSA’s. The RSA’s are subject to service-based vesting, typically between one and four years, where a specific period of continued employment must pass before an award vests. The expense associated with these awards is recognized on a straight-line basis over the respective vesting period, with forfeitures accounted for as they occur. For any vesting tranche of an award, the cumulative amount of compensation cost recognized is equal to the portion of the grant‑date fair value of the award tranche that is actually vested at that date.

As of June 30, 2018, the Company has not granted RSA’s under the 2018 Plan.

The following table summarizes restricted stock activity during the six months ended June 30, 2018:

	Shares
Restricted stock at December 31, 2017	328,122
Shares granted	267,454
Shares forfeited	—
Shares vested	(119,205)
Restricted stock at June 30, 2018	476,371

Under the Employee Stock Purchase Plan (“ESPP”), as amended and restated effective April 1, 2018, 325,000 shares of common stock have been reserved for issuance. Eligible employees may designate not more than 10% of their cash compensation to be deducted each pay period for the purchase of common stock under the Purchase Plan. Participants may purchase not more than 1,000 shares or $25,000 of common stock in any one calendar year. Each January 31 and July 31 shares of common stock are purchased with the employees’ payroll deductions from the immediately preceding six months at a price per share of 85% of the lesser of the market price of the common stock on the purchase date or the market price of the common stock on the date of entry into an offering period. In the first half of 2018 and 2017, respectively, 5,497 and 6,065 shares of common stock were issued under the ESPP. The Company issues new shares through its transfer agent upon employee stock purchase.

11. Reportable Segments

The Company has two reportable segments: (i) Leasing and Related Operations which involves acquiring and leasing, primarily pursuant to operating leases, commercial aircraft, aircraft engines and other aircraft equipment and the selective purchase and resale of commercial aircraft engines and other aircraft equipment and other related businesses and (ii) Spare Parts Sales which involves the purchase and resale of after-market engine and airframe parts, whole engines, engine modules and portable aircraft components.

The Company evaluates the performance of each of the segments based on profit or loss after general and administrative expenses. While the Company believes there are synergies between the two business segments, the segments are managed separately because each requires different business strategies.

During the second quarter of 2018, the Company moved certain sales of leased equipment to the Spare Parts Sales segment from the Leasing and Related Operations segment and had no change in the determination of operating segments. In accordance with ASC 280-10, the Company has restated prior period information presented below to reflect this change in composition of its reportable segments.

The following tables present a summary of the reportable segments (in thousands):

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the Unaudited Condensed Consolidated Financial Statements and notes thereto included under Part I, Item 1 of this Quarterly Report on Form 10-Q. In addition, reference should be made to our audited Consolidated Financial Statements and notes thereto and related “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2017 Annual Report on Form 10-K (“2017 Form 10-K”).

Overview

Our core business is acquiring and leasing commercial aircraft and aircraft engines and related aircraft equipment pursuant to operating leases, and the selective sale of such aircraft, engines and related equipment, all of which we sometimes collectively refer to as “equipment.” As of June 30, 2018, all of our leases were operating leases. As of June 30, 2018, we had 91 lessees in 47 countries. Our portfolio is continually changing due to acquisitions and sales. As of June 30, 2018, our lease portfolio consisted of 246 engines and related equipment, 15 aircraft and 10 other leased parts and equipment with an aggregate net book value of $1,542.3 million. As of June 30, 2018, we also managed 471 engines, aircraft and related equipment on behalf of other parties.

Our wholly owned subsidiary Willis Asset Management Limited (“Willis Asset Management”) is focused on the engine management and consulting business. 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 from third parties.

We actively manage our portfolio and structure our leases to maximize the residual values of our leased assets. Our leasing business focuses on popular Stage III commercial jet engines manufactured by CFMI, General Electric, Pratt & Whitney, Rolls Royce and International Aero Engines. These engines are the most widely used engines in the world, powering Airbus, Boeing, McDonnell Douglas, Bombardier and Embraer aircraft. Also, on a more limited basis, we lease aircraft that typically utilize the engines that are in our portfolio.

Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies and estimates from the information provided in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our 2017 Form 10-K.

Results of Operations

Three months ended June 30, 2018 compared to the three months ended June 30, 2017:

Lease Rent Revenue. Lease rent revenue increased by $11.7 million or 37.5% to $43.1 million in the three months ended June 30, 2018 from $31.3 million for the three months ended June 30, 2017. Lease rent revenue consists of rental income from long-term and short-term engine leases, aircraft leases, and other leased parts and equipment. The increase is primarily driven by an increase in lease rates and increased net book value of the leased assets. During the three months ended June 30, 2018, we purchased equipment (including capitalized costs) totaling $104.5 million, which primarily consisted of seven engines purchased for our lease portfolio. During the three months ended June 30, 2017, we purchased equipment (including capitalized costs) totaling $79.6 million, primarily consisting of 10 engines and six aircraft.

19

The aggregate net book value of equipment held for lease at June 30, 2018 and June 30, 2017, was $1,542.3 million and $1,160.5 million, respectively, an increase of 32.9%. Average utilization (based on net book value) for the three months ended June 30, 2018 decreased to approximately 87% from 88% for the three months ended June 30, 2017. Utilization was influenced by the Company’s acquisition of new equipment.

Maintenance Reserve Revenue. Maintenance reserve revenue increased $10.2 million, or 85.5%, to $22.0 million for the three months ended June 30, 2018 from $11.9 million for the three months ended June 30, 2017. During the same three month period of 2018, we recognized $13.7 million Maintenance reserve revenue on our short-term, non-reimbursable leases, compared to $9.8 million in the prior year period.

During the three months ended June 30, 2018, two reimbursable leases terminated resulting in the recognition of $8.3 million in Maintenance reserve revenue. Comparatively, during the same three months of 2017, one reimbursable lease terminated resulting in the recognition of $2.1 million in Maintenance reserve revenue. 

Spare Parts and Equipment Sales.  Spare parts and equipment sales decreased by $12.3 million, or 63.6%, to $7.1 million for the three months ended June 30, 2018 compared to $19.4 million for the three months ended June 30, 2017.  Spare parts sales for the three months ended June 30, 2018 were $7.1 million compared to $6.5 million in the comparable period in 2017. There were no equipment sales in the second quarter of 2018, compared to the sale of three airframes for $12.9 million in the second quarter of 2017.

Gain on Sale of Leased Equipment. Gain on sale of leased equipment decreased by $3.3 million, or 93.1% to $0.2 million in the three months ended June 30, 2018 from $3.5 million in the three months ended June 30, 2017.  The $0.2 million as of June 30, 2018 reflects the sale of two engines, one aircraft and other related equipment. During the three months ended June 30, 2017, we sold four engines and other related equipment, generating a net gain of $3.5 million.  

Other Revenue.  Other revenue increased by $0.2 million, or 9.0%, to $1.9 million in the three months ended June 30, 2018 from $1.7 million in the three months ended June 30, 2017. Other revenue primarily reflects fees earned related to engines managed on behalf of third parties and service fee revenue.  

Depreciation and Amortization Expense. Depreciation and amortization expense increased by $2.4 million, or 14.8%, to $18.4 million for the three months ended June 30, 2018 compared to $16.0 million for the three months ended June 30, 2017. The increase reflects the larger net book value of the lease portfolio, and the change in mix of portfolio, as compared to the prior year period.

Cost of Spare Parts and Equipment Sales.  Cost of spare parts and equipment sales decreased by $8.8 million, or 59.7%, to $5.9 million for the three months ended June 30, 2018 compared to $14.7 million for the three months ended June 30, 2017. Cost of spare parts for three months ended June 30, 2018 were $5.9 million compared to $4.7 million in the prior year period. Cost of spare parts sales for the three months ended June 30, 2017 include $0.9 million of reclassifications of scrap inventory write-offs and lower of cost or market write-downs that were previously presented within the Write-down of equipment expense line item. The reclassification is reflected as an increase to Cost of spare parts and equipment sales and a decrease to Write-down of equipment.

 There were no costs of equipment sales in the second quarter of 2018, compared to $9.9 million from the sale of three airframes in the second quarter of 2017.

Write-down of Equipment. Write-down of equipment increased by $2.2 million, or 164.8%, to $3.6 million for the three months ended June 30, 2018 compared to $1.4 million for the three months ended June 30, 2017. During the three months ended June 30, 2018, we wrote down three engines totaling $3.6 million, compared to one engine for a total write-down of $1.4 million in the three months ended June 30, 2017.

General and Administrative Expenses. General and administrative expenses increased by $3.7 million, or 28.5%, to $16.8 million for the three months ended June 30, 2018 compared to $13.1 million for the three months ended June 30, 2017. The increase, when compared to the prior year period, primarily reflects additional expenses associated with the transition of personnel to our new Coconut Creek facility, as well as other transition related expenses.  

Technical Expense. Technical expense increased by $0.8 million, or 32.0%, to $3.2 million for the three months ended June 30, 2018 compared to $2.4 million for the three months ended June 30, 2017. Technical expense consists

20

of the cost of engine repairs, engine thrust rental fees, outsourced technical support services, sublease engine rental expense, engine storage and freight costs. This increase primarily reflects an increase of $1.0 million in engine maintenance costs and an increase of $0.1 million in engine freight costs.

Interest Expense. Interest expense increased to $15.1 million for the three months ended June 30, 2018 compared to $11.3 million for the three months ended June 30, 2017. This increase is a result of higher debt obligation balances and increased borrowing cost in 2018 associated with our LIBOR based borrowings and our WEST III notes. Debt obligations outstanding, net of unamortized debt issuance costs, as of June 30, 2018 and 2017, were $1,232.8 million and $921.8 million, respectively, of which $666.0 million and $651.0, respectively, was tied to one-month LIBOR. As of June 30, 2018 and 2017, one-month LIBOR was 2.09% and 1.22%, respectively.

Income Tax Expense. Income tax expense was $3.2 million for the three months ended June 30, 2018 compared to $4.2 million for the three months ended June 30, 2017. The effective tax rate for the first quarter of 2018 was 27.9% compared to 41.0% in the prior year period. This decrease was predominantly due to the Tax Cuts and Jobs Act of 2017 (the “Act”) that was signed into law making significant changes to the Internal Revenue Code, decreasing federal corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017, lower forecasted permanent non-deductible expenses for executive compensation (IRS code 162(m) calculation) and changes in the proportions of revenue generated within and outside of California.

Six months ended June 30, 2018 compared to the six months ended June 30, 2017:

Lease Rent Revenue. Lease rent revenue increased by $21.2 million or 34.4% to $82.7 million in the six months ended June 30, 2018 from $61.6 million for the six months ended June 30, 2017. The increase is primarily driven by an increase in lease rates and increased net book value of the leased assets. During the six months ended June 30, 2018, we purchased equipment (including capitalized costs) totaling $243.1 million, which primarily included 27 engines purchased for our lease portfolio. During the six months ended June 30, 2017, we purchased equipment (including capitalized costs) totaling $112.2 million, which primarily included 14 engines and eight aircraft.

The aggregate net book value of equipment held for lease at June 30, 2018 and June 30, 2017, was $1,542.3 million and $1,160.5 million, respectively, an increase of 32.9%. Average utilization (based on net book value) for the six months ended June 30, 2018 decreased to approximately 87% from 89% for the six months ended June 30, 2017. Utilization was influenced by the Company’s acquisition of new equipment.

Maintenance Reserve Revenue. Maintenance reserve revenue decreased $6.4 million, or 14.5%, to $37.5 million for the six months ended June 30, 2018 from $43.8 million for the six months ended June 30, 2017. During the same six month period of 2018, we recognized $26.8 million Maintenance reserve revenue on our short-term, non-reimbursable leases, compared to $20.2 million in the prior year period.

During the six months ended June 30, 2018, one non-reimbursable lease modification and three reimbursable lease terminations resulted in the recognition of $10.7 million in Maintenance reserve revenue. Comparatively, during the same period of 2017, seven reimbursable leases terminated resulting in the recognition of $23.6 million in Maintenance reserve revenue. 

Spare Parts and Equipment Sales.  Spare parts and equipment sales decreased by $18.6 million, or 58.3%, to $13.3 million for the six months ended June 30, 2018 compared to $32.0 million for the six months ended June 30, 2017.  Spare parts sales for the six months ended June 30, 2018 were $13.3 million compared to $12.7 million in the comparable period in 2017. There were no equipment sales in the first half of 2018, compared to the sale of four airframes and one engine for $19.3 million in the first half of 2017.

Gain on Sale of Leased Equipment. Gain on sale of leased equipment decreased by $3.6 million, or 80.4% to $0.9 million in the six months ended June 30, 2018 from $4.5 million in the six months ended June 30, 2017. During the six months ended June 30, 2018 we sold three engines and two aircraft for a net gain of $0.9 million, compared to seven engines and other related equipment generating a net gain of $4.5 million during the six months ended June 30, 2017.

Other Revenue.  Other revenue decreased by $0.1 million, or 3.5%, to $3.8 million in the six months ended June 30, 2018 from $3.9 million in the six months ended June 30, 2017.

21

Depreciation and Amortization Expense. Depreciation and amortization expense increased by $3.1 million, or 9.5%, to $35.7 million for the six months ended June 30, 2018 compared to $32.6 million for the six months ended June 30, 2017. The increase reflects the larger net book value of the lease portfolio, and the change in mix of portfolio, as compared to the prior year period.

Cost of Spare Parts and Equipment Sales.  Cost of spare parts and equipment sales decreased by $14.3 million, or 57.2%, to $10.7 million for the six months ended June 30, 2018 compared to $25.0 million for the six months ended June 30, 2017. Cost of spare parts for six months ended June 30, 2018 were $10.7 million compared to $10.4 million in the prior year period. Cost of spare parts sales for the six months ended June 30, 2017 include $1.8 million of reclassifications of scrap inventory write-offs and lower of cost or market write-downs that were previously presented within the Write-down of equipment expense line item. The reclassification is reflected as an increase to Cost of spare parts and equipment sales and a decrease to Write-down of equipment.

There were no costs of equipment sales for the six months ended June 30, 2018, compared to $14.6 million in the prior year period.

Write-down of Equipment. Write-down of equipment decreased by $9.9 million, or 73.4%, to $3.6 million for the six months ended June 30, 2018 compared to $13.4 million for the six months ended June 30, 2017. The $3.6 million for the six months ended June 30, 2018 reflects the write-down of three engines to be parted out. A write-down of equipment totaling $4.4 million was recorded in the six months ended June 30, 2017 due to a management decision to consign four engines for part-out and sale, in which the asset’s net book value exceeded the estimated proceeds.  A further write-down of $9.0 million was recorded due to the adjustment of the carrying value for four engines within the portfolio to reflect estimated market value.

General and Administrative Expenses. General and administrative expenses increased by $6.1 million, or 23.3%, to $32.4 million for the six months ended June 30, 2018 compared to $26.3 million for the six months ended June 30, 2017. The increase, when compared to the prior year period, primarily reflects additional expenses associated with the transition of personnel to our new Coconut Creek facility, as well as other transition related expenses.  

Technical Expense. Technical expense increased by $2.2 million, or 45.8%, to $6.9 million for the six months ended June 30, 2018 compared to $4.7 million for the six months ended June 30, 2017. This increase primarily reflects an increase of $2.0 million in engine maintenance costs and an increase of $0.6 million in engine freight costs.

Interest Expense. Interest expense increased to $28.7 million for the six months ended June 30, 2018 compared to $22.2 million for the six months ended June 30, 2017. This increase is a result of higher debt obligation balances and increased borrowing cost in 2018 associated with our LIBOR based borrowings and our WEST III notes.

Income Tax Expense. Income tax expense was $5.8 million for the six months ended June 30, 2018 compared to $10.4 million for the six months ended June 30, 2017. The effective tax rate for the first half of 2018 was 27.2% compared to 42.4% in the prior year period. This decrease was predominantly due to the Tax Cuts and Jobs Act of 2017 (the “Act”) that was signed into law making significant changes to the Internal Revenue Code, decreasing federal corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017, lower forecasted permanent non-deductible expenses for executive compensation (IRS code 162(m) calculation) and changes in the proportions of revenue generated within and outside of California.

Financial Position, Liquidity and Capital Resources

At June 30, 2018, the Company had $46.8 million of cash, cash equivalents and restricted cash. We finance our growth through borrowings secured by our equipment lease portfolio. Cash of approximately $199.0 million and $93.0 million in the six months ended June 30, 2018 and 2017, respectively, was derived from this activity. In these same time periods, $53.3 million and $72.8 million, respectively, was used to pay down related debt.

Cash Flows Discussion

Cash flows provided by operating activities was $72.7 million and $79.3 million in the six months ended June 30, 2018 and 2017, respectively. The decrease was primarily due to a change in operating lease related receivables and spare parts inventory.

22

Cash flows from operations are driven significantly by payments made under our lease agreements, which comprise lease rent revenue, security deposits and maintenance reserves, and are offset by interest expense and general and administrative costs. Cash received from maintenance reserve arrangements and lease security deposits for some of our engines on lease are restricted per our WEST II and WEST III debt agreements. The lease revenue stream, in the short-term, is at fixed rates while a portion of our debt is at variable rates. If interest rates increase, it is unlikely we could increase lease rates in the short term and this would cause a reduction in our earnings and operating cash flows. Lease rent revenue and maintenance reserves are also affected by the amount of equipment off-lease. Approximately 88% and 89%, by book value, of our lease assets were on lease at June 30, 2018 and December 31, 2017, respectively. The average utilization rate was approximately 87% and 89% for the six months ended June 30, 2018 and 2017, respectively. The decline in percentage year over year is a direct result of purchases made in the first half of 2018, a large portion of which were off-lease. If there is any increase in off-lease rates or deterioration in lease rates that are not offset by reductions in interest rates, there will be a negative impact on earnings and cash flows from operations.

Cash flows used in investing activities was $206.4 million and $72.9 million in the six months ended June 30, 2018 and 2017, respectively. Our primary use of funds is for the purchase of equipment for operating lease. Purchases of equipment held for operating lease and for sale (including capitalized costs and prepaid deposits made in the period) totaled $243.1 million and $112.2 million for the six months ended June 30, 2018 and 2017, respectively.

Cash flows provided by financing activities was $133.2 million for the six months ended June 30, 2018 and primarily reflected $199.0 million in proceeds from the issuance of debt obligations, offset by $53.3 million in principal payments. Cash flows provided by financing activities of $15.8 million in the six months ended June 30, 2017 and primarily reflected $93.0 million in proceeds from debt obligations, offset by $72.8 million in principal payments.

Debt Obligations and Covenant Compliance

At June 30, 2018, Debt obligations consist of loans totaling $1,232.8 million payable with interest rates varying between approximately 2.6% and 6.4%. Substantially all of our assets are pledged to secure our obligations to creditors. For further information on our debt instruments, see the "Debt Obligations" Note 4 in Part I, Item 1 of this Form 10-Q.

Virtually all of the Company’s debt requires our ongoing compliance with the covenants of each financing, including debt/equity ratios, minimum tangible net worth and minimum interest coverage ratios, and other eligibility criteria including customer and geographic concentration restrictions. Under our revolving credit facility, we can borrow no more than 85% of an engine’s net book value and 65% of an airframe’s or spare parts inventory’s net book value. Therefore we must have other available funds for the balance of the purchase price of any new equipment to be purchased or we will not be permitted to draw on our revolver. The facilities are also cross-defaulted against other facilities. If we do not comply with the covenants or eligibility requirements, we may not be permitted to borrow additional funds and accelerated payments may become necessary. Additionally, much of the debt is secured by engines and aircraft, and to the extent that engines or aircraft are sold, repayment of that portion of the debt could be required.

At June 30, 2018, we are in compliance with the covenants specified in the revolving credit facility, including the Interest Coverage Ratio requirement of at least 2.25 to 1.00, and the Total Leverage Ratio requirement to remain below 4.25 to 1.00. As defined in the revolving credit facility Credit Agreement, the Interest Coverage Ratio is the ratio of Earnings before Interest, Taxes, Depreciation and Amortization and other one-time charges (EBITDA) to Consolidated Interest Expense and the Total Leverage Ratio is the ratio of Total Indebtedness to Tangible Net Worth. At June 30, 2018, we are in compliance with the covenants specified in the WEST II and WEST III indentures, servicing and other related agreements.

Contractual Obligations and Commitments

Repayments of our gross debt obligations primarily consist of scheduled installments due under term loans and are funded by the use of unrestricted cash reserves and from cash flows from ongoing operations. The table below summarizes our contractual commitments at June 30, 2018:

			Payment due by period (in thousands)
			Less than						More than
	Total		1 Year		1-3 Years		3-5 Years		5 Years
Debt obligations	$	1,249,476	$	38,547	$	742,420	$	218,678	$	249,831
Interest payments under debt obligations		254,235		59,035		106,167		38,475		50,558
Operating lease obligations		5,231		1,358		1,386		1,141		1,346
Purchase obligations		141,833		141,833		—		—		—
Total	$	1,650,775	$	240,773	$	849,973	$	258,294	$	301,735

We have estimated the interest payments due under debt obligations by applying the interest rates applicable at June 30, 2018 to the remaining debt, adjusted for the estimated debt repayments identified in the table above. Actual interest payments made will vary due to changes in the rates for one-month LIBOR.

We believe our equity base, internally generated funds and existing debt facilities are sufficient to maintain our level of operations through the next twelve months. However, a decline in the level of internally generated funds or an inability to obtain lease commitments for our off-lease engines (including new engines from manufacturers), would limit availability of funding under our existing debt facilities, and/or result in a significant step-up in borrowing costs. Such limits on availability of funding and increased borrowing costs would impair our ability to sustain our level of operations. We continue to discuss additions to our capital base with our commercial and investment banks. If we are not able to access additional capital, our ability to continue to grow our asset base consistent with historical trends could be constrained and our future growth limited to that which can be funded from internally generated capital.

For any interest rate swaps that we enter into, we will be exposed to risk in the event of non-performance of the interest rate hedge counter-parties. We anticipate that we may hedge additional amounts of our floating rate debt in the future.

Recent Accounting Pronouncements

The most recent adopted accounting pronouncements and accounting pronouncements to be adopted by the Company are described in Note 1 to our unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q.

Item 3.Quantitative and Qualitative Disclosures about Market Risk

Our primary market risk exposure is that of interest rate risk. A change in LIBOR rates would affect our cost of borrowing. Increases in interest rates, which may cause us to raise the implicit rates charged to our customers, could result in a reduction in demand for our leases. Alternatively, we may price our leases based on market rates so as to keep the fleet on-lease and suffer a decrease in our operating margin due to interest costs that we are unable to pass on to our customers. As of June 30, 2018, $666.0 million of our outstanding debt is variable rate debt. We estimate that for every one percent increase or decrease in interest rates on our variable rate debt, our annual interest expense would increase or decrease $5.7 million.

We hedge a portion of our borrowings from time to time, effectively fixing the rate of these borrowings. This hedging activity helps protect us against reduced margins on longer term fixed rate leases. Such hedging activities may limit our ability to participate in the benefits of any decrease in interest rates, but may also protect us from increases in interest rates. Furthermore, since lease rates tend to vary with interest rate levels, it is possible that we can adjust lease rates for the effect of change in interest rates at the termination of leases. Other financial assets and liabilities are at fixed rates.

We are also exposed to currency devaluation risk. Most of our leases require payment in U.S. dollars. During the six months ended June 30, 2018, 77% of our lease rent revenues came from non-United States domiciled lessees.  If

24

these lessees’ currency devalues against the U.S. dollar, the lessees could potentially encounter difficulty in making their lease payments.

No customer accounted for more than 10% of total lease rent revenue during the six months ended June 30, 2018 and 2017, respectively.

Item 4.Controls and Procedures

(a) Evaluation of disclosure controls and procedures. In accordance with Rule 13a-15b under the Securities Exchange Act of 1934, as amended (Exchange Act) we (with the participation of our Chief Executive Officer (CEO) and Chief Financial Officer (CFO)) carried out an evaluation of the effectiveness and design of our disclosure controls and procedures (as defined in Rules 13-15(e) and 15d-15(e) of the Exchange Act), as of the end of the period covered by this report.  Based on such evaluation, our CEO and CFO have concluded that such disclosure controls and procedures, are effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to Company’s management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Inherent Limitations on Controls. Management, including the CEO and CFO, does not expect that our disclosure controls and procedures will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.

(c) Changes in internal control over financial reporting. There has been no change in our internal controls over financial reporting during our fiscal quarter ended June 30, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 2.Unregistered Sales of Equity Securities and Use of Proceeds

(a) None.

(b) None.

(c) Issuer Purchases of Equity Securities. In September 2012, the Company announced that its Board of Directors authorized a plan to repurchase up to $100.0 million of its common stock over the next 5 years. The Board of Directors reaffirmed the repurchase plan in October 2016 and extended the plan to December 31, 2018.

There were no common stock repurchases, under our authorized plan, in the three months ended June 30, 2018.

Item 5.Other Information

On August 8, 2018, the Company issued a news release announcing the offering of approximately $373.4 million of fixed rate notes by Willis Engine Structured Trust IV, its direct, wholly-owned subsidiary.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

1.  Summary of Significant Accounting Policies

The significant accounting policies of Willis Lease Finance Corporation and its subsidiaries (collectively, the “Company”) were described in Note 1 to the audited consolidated financial statements included in the Company’s 2017 Annual Report on Form 10-K (“2017 Form 10-K”). There have been no significant changes in the Company’s significant accounting policies for the six months ended June 30, 2018.

(a)    Basis of Presentation

The accompanying Unaudited Condensed Consolidated Financial Statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission. Therefore, they do not include all information and footnotes normally included in annual consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the 2017 Form 10-K. In the opinion of management, the Unaudited Condensed Consolidated Financial Statements contain all adjustments (consisting principally of normal recurring accruals) necessary for a fair presentation of the condensed consolidated balance sheets, statements of income, statements of comprehensive income and statements of cash flows for such interim periods presented. Additionally, operating results for interim periods are not necessarily indicative of the results that can be expected for a full year.

In accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. These estimates and judgments are based on historical experience and other assumptions that management believes are reasonable. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. The significant estimates made in the accompanying Unaudited Condensed Consolidated Financial Statements include certain assumptions related to goodwill, intangible assets, long-lived assets, assets held for sale, estimated income taxes and stock-based compensation. Actual results may differ from these estimates under different assumptions or conditions.

(b)     Reclassifications

In conjunction with our review of the fourth quarter of 2017, the Company reclassified scrap inventory write-offs and inventory lower of cost or market write-downs that were previously presented within Write-down of equipment to the Cost of spare parts and equipment sales line item. The first half of 2017 was impacted by an adjustment of $1.8 million and is reflected as an increase to Cost of spare parts and equipment sales and a decrease to Write-down of equipment. These reclassified items had no effect on the reported results of operations, financial condition or statements of cash flows.

(c)     Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, including variable interest entities (“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 VIE 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.  

(d)    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 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 Accounting Standards Codification (“ASC”) 606) effective on January 1, 2018 using the modified retrospective approach applied only to contracts not completed as of the date of adoption. Please see Note 2 "Revenue from Contracts with Customers" for the required disclosures related to the impact of adopting this standard and a discussion of the Company's updated policies related to revenue recognition and accounting for costs to obtain and fulfill a customer contract.

In January 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” that eliminates “Step 2” from the goodwill impairment test. The Company has 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 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” 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 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 Act is recognized. The Company has 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.

Recent Accounting Pronouncements To Be Adopted by the Company

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued ASU 2016-02 to increase transparency and comparability among organizations recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under ASU 2016-02, lessors will account for leases using an approach that is substantially equivalent to existing GAAP for sales-type leases, direct financing leases and operating leases. Unlike current guidance, however, a lease with collectability uncertainties may be classified as a sales-type lease. If collectability of lease payments, plus any amount necessary to satisfy a lessee residual value guarantee, is not probable, lease payments received will be recognized as a deposit liability and the underlying assets will not be derecognized until collectability of the remaining amounts becomes probable. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and must be adopted using a modified retrospective transition. 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.

2. Revenue from Contracts with Customers

As of January 1, 2018, the Company adopted ASU 2014-09 and all subsequent ASUs that modified ASC 606. While only a portion of the Company’s revenues is impacted by this guidance as it does not apply to contracts falling under the leasing standard, as part of the implementation process the Company performed an analysis to identify accounting policies that needed to change and additional disclosures that are  required. The Company considered factors such as customer contracts with unique revenue recognition considerations, the nature and type of goods and services offered, the degree to which contracts include multiple performance obligations or variable consideration, and the pattern in which revenue is currently recognized, among other things. All revenue streams applicable to the new standard (Spare parts and equipment sales and Managed services which is reflected within Other revenue) were evaluated by management. The Company considered recognition under the new standard and concluded the timing of the Company’s revenue recognition will remain the same. 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 following table disaggregates revenue by major source for the three and six months ended June 30, 2018 (in thousands):

(1) Represents revenue generated between our reportable segments.

(2) Leasing revenue is recognized under the lease accounting guidance in ASC 840 Leases, and therefore qualifies for the scope exception under ASC 606.

(3) Gain on sale of leased equipment is accounted for under ASC 610-20,Gains and losses from the derecognition of nonfinancial assets.

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 or the lease terminates, 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 June 30, 2018, the Company had an aggregate of approximately $4.1 million in lease rent and $3.5 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 lease 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.

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 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 engine 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. The parts are sold at a fixed price with no right of return and are shipped “FOB shipping point.” In determining the performance obligation, management has identified the promise in the contract to be the shipment of the spare parts to the customer.When the spare parts are shipped FOB shipping point, 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 ASC 606-10-5-86 and as the Company is not obliged to perform additional services under these arrangements, the shipment of the spare parts is the performance obligation. 

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.  There is one performance obligation identified, as discussed above, which is the shipment of the parts 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., on the shipment date) 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. The result of allocation consideration on this basis is consistent with the overall core principal of ASC 606 (to recognize revenue in an amount that depicts the consideration to which the Company expects to be entitled in exchange for the promised goods or services). As each of the services provided within the contract have separate prices, the Company allocates the stated 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 will continue utilizing 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 will continue to be 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 June 30, 2018. At June 30, 2018, unbilled revenue was $0.7 million and the Company expects it to be fully recognized by December 31, 2018. Additionally, Managed services are presented within the Other revenue line in the condensed consolidated statements of income.

Virtually all of the above debt requires ongoing compliance with the covenants of each financing, including debt/equity ratios, minimum tangible net worth and minimum interest coverage ratios, and other eligibility criteria including customer and geographic concentration restrictions. The Company also has certain negative financial covenants such as liens, advances, change in business, sales of assets, dividends and stock repurchases. These covenants are tested either monthly or quarterly and the Company was in full compliance with all financial covenant requirements at June 30, 2018.

The Company maintains a revolving credit facility to finance the acquisition of aircraft engines for lease as well as for general working capital purposes. The $890 million revolving credit facility has an accordion feature which would expand the entire credit facility up to $1 billion. The interest rate is adjusted quarterly, based on the Company’s leverage ratio, as calculated under the terms of the revolving credit facility.

Derivative Instruments

5.  Derivative Instruments

The Company periodically holds interest rate derivative instruments to mitigate exposure to changes in interest rates, in particular one-month LIBOR, with $666.0 million and $501.3 million of borrowings at June 30, 2018 and December 31, 2017, respectively, at variable rates. As a matter of policy, management does not use derivatives for speculative purposes.  During 2016, the Company entered into one interest rate swap agreement which has a notional outstanding amount of $100.0 million, with a remaining term of 34 months as of June 30, 2018. The fair value of the swap at June 30, 2018 and December 31, 2017 was $2.5 million and $1.1 million, respectively, representing a net asset. The Company recorded a gain of $94 thousand and a loss of $0.2 million in the three months ended June 30, 2018 and 2017, respectively, and a gain of $69 thousand and a loss of $0.4 million during the six months ended June 30, 2018 and 2017, respectively, from derivative instruments.

The Company estimates the fair value of  derivative instruments using a discounted cash flow technique and has used creditworthiness inputs that corroborate observable market data evaluating the Company’s and counterparty’s risk of non-performance. Valuation of the derivative instruments requires certain assumptions for underlying variables and the use of different assumptions would result in a different valuation. Management believes it has applied assumptions consistently during the period. The Company applies hedge accounting and accounts for the change in fair value of its cash flow hedges through other comprehensive income for all derivative instruments.

Effect of Derivative Instruments on Earnings in the Statements of Income and on Comprehensive Income

The following tables provide additional information about the financial statement effects related to the cash flow hedges for the three and six months ended June 30, 2018 and 2017:

Total	$	1,415	$	(3)	Total	$	(69)	$	400

The derivatives were designated in a cash flow hedging relationship with the effective portion of the change in fair value of the derivative reported in the cash flow hedges subaccount of accumulated other comprehensive income.

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 or it is probable that the forecasted transaction will not occur. The ineffective portion of the hedges is recorded in earnings in the current period. However, these are highly effective hedges and no significant ineffectiveness occurred in the periods presented.

Counterparty Credit Risk

The Company evaluates the creditworthiness of the counterparties under its hedging agreements. The counterparty for the interest rate swap in place during 2018 was a large financial institution in the United States that possessed an investment grade credit rating. Based on this rating, the Company believes that the counterparty was creditworthy and that their continuing performance under the hedging agreement was probable, and did not require the counterparty to provide collateral or other security to the Company.

Income tax expense for the three and six months ended June 30, 2018 was $3.2 million and $5.8 million, respectively. Income tax expense for the three and six months ended June 30, 2017 was $4.2 million and $10.4 million, respectively. The effective tax rate for the three and six months ended June 30, 2018 was 27.9% and 27.2%, respectively. The effective tax rate for the three and six months ended June 30, 2017 was 41.0% and 42.4%, respectively. The 2018 tax rate reflects the enactment of the Tax Cuts and Jobs Act of 2017 (the “Act”) which made significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017.

The Company records tax expense or benefit for unusual or infrequent items discretely in the period in which they occur. The Company’s tax rate is subject to change based on changes in the mix of assets leased to domestic and foreign lessees, the proportions of revenue generated within and outside of California, the amount of executive compensation exceeding $1.0 million as defined in IRS code 162(m) and numerous other factors, including changes in tax law.

Fair Value of Financial Instruments

Fair Value Measurements

Fair Value Measurements

7. Fair Value Measurements

The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation. Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of judgment, and therefore cannot be determined with precision.

Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also establishes the following three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments:

· Cash and cash equivalents, restricted cash, operating lease related receivables, and accounts payable: The amounts reported in the accompanying Consolidated Balance Sheets approximate fair value due to their short-term nature.

· Debt obligations: The carrying amount of the Company’s outstanding balance on its Debt obligations as of June 30, 2018 and December 31, 2017 was estimated to have a fair value of approximately $1,089.5 million and $1,090.0 million, respectively, based on the fair value of estimated future payments calculated using interest rates that approximate prevailing market rates at each period end (Level 2 inputs).

Assets Measured and Recorded at Fair Value on a Recurring Basis

As of June 30, 2018 and December 31, 2017, the Company measured the fair value of its interest rate swap of $100.0 million (notional amount) based on Level 2 inputs, due to the usage of inputs that can be corroborated by observable market data. The Company estimates the fair value of derivative instruments using a discounted cash flow technique and has used creditworthiness inputs that corroborate observable market data evaluating the Company’s and counterparties’ risk of non-performance. The interest rate swap agreement had a net fair value of $2.5 million and $1.1 million as of June 30, 2018 and December 31, 2017, respectively.  For the six months ended June 30, 2018, $69 thousand was realized through the income statement as a decrease in interest expense. For the six months ended June 30, 2017, $0.4 million was realized through the income statement as an increase in interest expense.

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company determines fair value of long-lived assets held and used, such as Equipment held for operating lease and Equipment held for sale, by reference to independent appraisals, quoted market prices (e.g. an offer to purchase) and other factors. An impairment charge is recorded when the carrying value of the asset exceeds its fair value. The Company used Level 2 inputs to measure write-downs of equipment held for lease, equipment held for sale and spare parts inventory as of June 30, 2018 and December 31, 2017.

A write-down of $3.6 million was recorded during the six months ended June 30, 2018 for three engines due to a management decision to part-out the engines, in which the net book values exceeded the estimated proceeds.

A write-down of $13.4 million was recorded during the six months ended June 30, 2017 for four engines and three aircraft for which their leases ended or were modified in the period. Management evaluated the equipment return condition, end of lease compensation, accumulated maintenance reserves and expected future proceeds from part out and sale to record its initial best estimate of impairment.

Earnings Per Share

Earnings Per Share

8.  Earnings Per Share

Basic earnings per common share is computed by dividing net income, less preferred stock dividends and accretion of preferred stock issuance costs, by the weighted average number of common shares outstanding for the period. Treasury stock is excluded from the weighted average number of shares of common stock outstanding. Diluted earnings per share attributable to common stockholders is computed based on the weighted average number of shares of common stock and dilutive securities outstanding during the period. Dilutive securities are common stock equivalents that are freely exercisable into common stock at less than market prices or otherwise dilute earnings if converted. The net effect of common stock equivalents is based on the incremental common stock that would be issued upon the vesting of restricted stock using the treasury stock method. Common stock equivalents are not included in diluted earnings per share when their inclusion is antidilutive. Additionally, redeemable preferred stock is not convertible and does not affect dilutive shares.

The computations of diluted weighted average earnings per common share do not include approximately 0.3 million and 0.1 million restricted shares for the three and six months ended June 30, 2018, respectively, as the effect of their inclusion would have been antidilutive to earnings per share. There were no anti-dilutive shares during the three months ended June 30, 2017 and 43 thousand anti-dilutive shares excluded from the computation of diluted weighted average earnings per common share during the six months ended June 30, 2017. The difference between average common shares outstanding to calculate basic and assuming full dilution is due to restricted stock issued under the 2007 Stock Incentive Plan.

The following table presents the calculation of basic and diluted EPS:

Total Stock Compensation Expense	$	1,660	$	1,200	$	2,585	$	2,074

The 2007 Stock Incentive Plan (the “2007 Plan”) was adopted on May 24, 2007. Under this 2007 Plan, a total of 2,800,000 shares are authorized for stock based compensation available in the form of either restricted stock awards (“RSA’s”) or stock options. The RSA’s are subject to service-based vesting, typically between one and four years, where a specific period of continued employment must pass before an award vests. The expense associated with these awards is recognized on a straight-line basis over the respective vesting period, with forfeitures accounted for as they occur. For any vesting tranche of an award, the cumulative amount of compensation cost recognized is equal to the portion of the grant‑date fair value of the award tranche that is actually vested at that date.

As of June 30, 2018, the Company has granted 2,883,414 RSA’s under the 2007 Plan. Of this amount, 166,744 shares were cancelled and returned to the pool of shares which could be granted under the 2007 Plan resulting in a net number of 83,330 shares available for future issuance. The fair value of the restricted stock awards equaled the stock price at the grant date. There are no stock options outstanding under the 2007 Plan.

The 2018 Stock Incentive Plan (the “2018 Plan”) was adopted on May 24, 2018. Under this 2018 Plan, a total of 800,000 shares are authorized for stock based compensation, plus the number of shares remaining under the 2007 Plan and any future forfeited awards under the 2007 Plan, in the form of RSA’s. The RSA’s are subject to service-based vesting, typically between one and four years, where a specific period of continued employment must pass before an award vests. The expense associated with these awards is recognized on a straight-line basis over the respective vesting period, with forfeitures accounted for as they occur. For any vesting tranche of an award, the cumulative amount of compensation cost recognized is equal to the portion of the grant‑date fair value of the award tranche that is actually vested at that date.

As of June 30, 2018, the Company has not granted RSA’s under the 2018 Plan.

The following table summarizes restricted stock activity during the six months ended June 30, 2018:

Under the Employee Stock Purchase Plan (“ESPP”), as amended and restated effective April 1, 2018, 325,000 shares of common stock have been reserved for issuance. Eligible employees may designate not more than 10% of their cash compensation to be deducted each pay period for the purchase of common stock under the Purchase Plan. Participants may purchase not more than 1,000 shares or $25,000 of common stock in any one calendar year. Each January 31 and July 31 shares of common stock are purchased with the employees’ payroll deductions from the immediately preceding six months at a price per share of 85% of the lesser of the market price of the common stock on the purchase date or the market price of the common stock on the date of entry into an offering period. In the first half of 2018 and 2017, respectively, 5,497 and 6,065 shares of common stock were issued under the ESPP. The Company issues new shares through its transfer agent upon employee stock purchase.

11. Reportable Segments

The Company has two reportable segments: (i) Leasing and Related Operations which involves acquiring and leasing, primarily pursuant to operating leases, commercial aircraft, aircraft engines and other aircraft equipment and the selective purchase and resale of commercial aircraft engines and other aircraft equipment and other related businesses and (ii) Spare Parts Sales which involves the purchase and resale of after-market engine and airframe parts, whole engines, engine modules and portable aircraft components.

The Company evaluates the performance of each of the segments based on profit or loss after general and administrative expenses. While the Company believes there are synergies between the two business segments, the segments are managed separately because each requires different business strategies.

During the second quarter of 2018, the Company moved certain sales of leased equipment to the Spare Parts Sales segment from the Leasing and Related Operations segment and had no change in the determination of operating segments. In accordance with ASC 280-10, the Company has restated prior period information presented below to reflect this change in composition of its reportable segments.

Summary of Significant Accounting Policies (Policies)

Summary of Significant Accounting Policies

Basis of Presentation

(a)    Basis of Presentation

The accompanying Unaudited Condensed Consolidated Financial Statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission. Therefore, they do not include all information and footnotes normally included in annual consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the 2017 Form 10-K. In the opinion of management, the Unaudited Condensed Consolidated Financial Statements contain all adjustments (consisting principally of normal recurring accruals) necessary for a fair presentation of the condensed consolidated balance sheets, statements of income, statements of comprehensive income and statements of cash flows for such interim periods presented. Additionally, operating results for interim periods are not necessarily indicative of the results that can be expected for a full year.

In accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. These estimates and judgments are based on historical experience and other assumptions that management believes are reasonable. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ materially from these estimates. The significant estimates made in the accompanying Unaudited Condensed Consolidated Financial Statements include certain assumptions related to goodwill, intangible assets, long-lived assets, assets held for sale, estimated income taxes and stock-based compensation. Actual results may differ from these estimates under different assumptions or conditions.

Reclassifications

(b)     Reclassifications

In conjunction with our review of the fourth quarter of 2017, the Company reclassified scrap inventory write-offs and inventory lower of cost or market write-downs that were previously presented within Write-down of equipment to the Cost of spare parts and equipment sales line item. The first half of 2017 was impacted by an adjustment of $1.8 million and is reflected as an increase to Cost of spare parts and equipment sales and a decrease to Write-down of equipment. These reclassified items had no effect on the reported results of operations, financial condition or statements of cash flows.

Principles of Consolidation

(c)     Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, including variable interest entities (“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 VIE 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.

Recent Accounting Pronouncements

(d)    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 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 Accounting Standards Codification (“ASC”) 606) effective on January 1, 2018 using the modified retrospective approach applied only to contracts not completed as of the date of adoption. Please see Note 2 "Revenue from Contracts with Customers" for the required disclosures related to the impact of adopting this standard and a discussion of the Company's updated policies related to revenue recognition and accounting for costs to obtain and fulfill a customer contract.

In January 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” that eliminates “Step 2” from the goodwill impairment test. The Company has 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 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” 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 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 Act is recognized. The Company has 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.

Recent Accounting Pronouncements To Be Adopted by the Company

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued ASU 2016-02 to increase transparency and comparability among organizations recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under ASU 2016-02, lessors will account for leases using an approach that is substantially equivalent to existing GAAP for sales-type leases, direct financing leases and operating leases. Unlike current guidance, however, a lease with collectability uncertainties may be classified as a sales-type lease. If collectability of lease payments, plus any amount necessary to satisfy a lessee residual value guarantee, is not probable, lease payments received will be recognized as a deposit liability and the underlying assets will not be derecognized until collectability of the remaining amounts becomes probable. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and must be adopted using a modified retrospective transition. 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.
