ALLEGIANT TRAVEL COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

Note 1 — Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of Allegiant Travel Company (the “Company”) and its majority-owned operating subsidiaries. The Company has no independent assets or operations, and all guarantees of the Company's publicly held debt are full and unconditional and joint and several. Any subsidiaries of the parent company other than the subsidiary guarantors are minor. All intercompany balances and transactions have been eliminated.

These unaudited consolidated financial statements reflect all normal recurring adjustments which management believes are necessary to present fairly the financial position, results of operations, and cash flows of the Company for the respective periods presented. Certain reclassifications have been made to prior year financial statements to conform to classifications used in the current year. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission for Form 10-Q. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company and notes thereto included in the annual report of the Company on Form 10-K for the year ended December 31, 2016,2017 and filed with the Securities and Exchange Commission.

The preparation of financial statements in conformity with U.S. GAAP requires management 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 revenues and expenses during the reporting period. Actual results may differ from these estimates.

Recent Accounting Pronouncements

Standards Effective in Future Years

In May 2014,February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" intended to create a unified model to determine when and how revenue is recognized. Under this ASU and subsequently issued amendments, the core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. Under the new standard, revenue related to certain air-related ancillary fees directly related to ticket revenue, such as seat fees and baggage fees, will no longer be considered distinct performance obligations separate from passenger travel and will be reclassified into scheduled service revenue. In addition, change fees previously recognized when incurred by the customer, will be deferred and recognized as revenue when air travel is provided and reclassified into scheduled service revenue.

The new standard is effective for annual and interim periods beginning after December 15, 2017, and the Company will adopt effective January 1, 2018. The Company continues to evaluate the impact on its financial statements of adopting this new accounting standard and believes that adoption will have little effect on earnings, although the classification of certain air-related ancillary fees, as described above, will change.

In February 2016, the FASB issued ASU 2016-02 related to leases. This standard will require leases with durations greater than twelve months to be recognized on the balance sheet as a lease liability and a corresponding right-of-use asset, and is effective for interim and annual reporting periods beginning after December 15, 2018 with early adoption permitted. The Company will adopt this standard effective January 1, 2019. The Company has not completed the assessment of this new standard. The Companystandard and believes adoption will have a significant impact on its consolidated balance sheets but is not expected to significantly change the recognition, measurement or presentation of associated expenseexpenses within the consolidated statements of income or cash flows.

Recently Adopted Standards

In August 2016, the FASB issued ASU 2016-15, which amends the guidance in Accounting Standards Codification ("ASC") 230 on the classification of certain cash receipts and payments in the statement of cash flows. The primary purpose of the ASU is to reduce the diversity in practice that has resulted from the lack of consistency onCompany adopted this topic. The standard is effective for annual and interim periods beginning after December 15, 2017, and the Company will adopt it effective January 1, 2018. Significant classification modifications are not expected

In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220)." This standard provides an option to reclassify stranded tax effects within accumulated other comprehensive income (loss) ("AOCI") to retained earnings. The Company adopted this standard effective January 1, 2018 and a one-time effect of $0.6 million was reclassified from AOCI to retained earnings as of June 30, 2018 as a result of this adoption.

In 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), (the "New Revenue Standard"). Under this ASU and subsequently issued amendments, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. The Company adopted this standard using the full retrospective transition method effective January 1, 2018 and recast prior year results. See Note 2, "Revenue Recognition" for more information on the financial impact of this adoption.



Under the New Revenue Standard, revenue for all air-related ancillary fees that are directly related to ticket revenue, such as seat fees and baggage fees, are no longer considered distinct performance obligations separate from passenger travel and are reclassified into passenger revenue. These are deemed part of the single performance obligation of providing passenger transportation. While the adoption of the New Revenue Standard did not have a significant effect on earnings, $167.6 million and $322.3 million of air-related ancillary fees for the three and six months ended June 30, 2018, respectively, are now classified as passenger revenue.

The adoption of the New Revenue Standard resulted in a net reduction to air traffic liability at December 31, 2017 of $5.9 million. This change resulted from the recognition of breakage revenue on issuance of credit vouchers that are expected to expire unused. In addition, recognition of revenues for fees associated with flight changes or cancellations are now deferred rather than being recognized at the time the fee is incurred. The Company recognizes revenue from the co-brand credit card program on the deferral method.

Bank of America has issued The Allegiant World Mastercard® in which points are earned and awarded to cardholders in exchange for consideration received under an agreement with a seven year scheduled duration expiring in 2023. Under this arrangement, the Company identified the following deliverables: travel points to be awarded (the travel component), use of the Company’s brand and access to its member lists, and certain other advertising and marketing elements (collectively the marketing component). Consideration received from the Company’s co-brand agreement is allocated between the two components based on the relative selling price of each deliverable. The Company applies a level of management judgment and estimation in determining the best estimate of selling price for each deliverable by considering multiple inputs and methods including, but not limited to, the redemption value of points awarded, discounted cash flows, brand value, volume discounts, published selling prices, number of points to be awarded and number of points to be redeemed.

Passenger Revenue

Passenger revenue is primarily composed of passenger ticket sales, credit voucher breakage, seat fees, baggage fees, and other travel-related services performed in conjunction with a passenger’s flight, as well as co-brand point redemptions as outlined below:

Scheduled service

Passenger tickets. The Company provides scheduled air transportation on limited-frequency, nonstop flights predominantly between under-served cities and popular leisure destinations. Sales of passenger tickets not yet flown are recorded in air traffic liability. Passenger revenue is recognized when transportation is provided or when ticket voucher breakage occurs.

The contract term of passenger tickets is 12 months and revenue associated with future travel will principally be recognized within this time frame. $187.8 million was recognized into passenger revenue during the six months ended June 30, 2018 that was recorded in the air traffic liability balance of $204.3 million at December 31, 2017.

Credit voucher breakage. The Company estimates the value of vouchers that will expire unused and recognizes revenue at the time the credit voucher is issued.

Air-related

Air-related revenue is primarily composed of services performed in conjunction with a passenger's flight and include baggage fees, the use of the Company’s website to purchase scheduled service transportation, advance seat assignments, and other services. Revenue for these services is recognized when the related transportation service is provided. Prior to the adoption of the New Revenue Standard, the majority of these fees were classified separately as Air-related ancillary charges.

Co-brand redemption

In relation to the travel component of the contract with Bank of America, the Company has a performance obligation to provide cardholders with points to be used for future travel award redemptions. Therefore, consideration received from Bank of America related to the travel component is deferred based on its relative selling price and is recognized into passenger revenue when the points are redeemed and the transportation is provided.

The following table presents the activity of the current and non-current point liabilities (in thousands):
 2018
Balance at January 1$8,903
Points awarded6,898
Points redeemed(5,730)
Balance at June 30$10,071

As of June 30, 2018, $6.9 million of the current points liability is reflected in Accrued liabilities and represents our current estimate of revenue to be recognized in the next twelve months based on historical trends, with the remaining balance reflected in Other noncurrent liabilities expected to be recognized into revenue in periods thereafter. See below, Third Party Products revenue, for discussion of the marketing component.

Third Party Products

Third party products revenue is generated from the sale of hotel rooms, rental cars, ticket attractions and co-brand marketing revenue.

Revenue from the sale of hotel rooms, rental cars, and ticket attractions is recognized at the time the product is utilized, such as the time a purchased hotel room is occupied. The Company follows the accounting standards for principal versus agent revenue arrangements to determine the amount of revenue to be recognized for each element of a bundled sale involving air-related charges and third party products, in addition to airfare. Revenue from the sale of third party products is recorded net (treatment as an agent) of amounts paid to wholesale providers, travel agent commissions, and transaction costs.

Pursuant to the co-brand agreement with Bank of America, the Company has various performance obligations collectively referred to as the marketing component. These obligations consist of use of the Company’s brand and access to its member lists, and certain other advertising and marketing elements. The marketing component is recorded as third party products revenue in the period in which points are awarded to the credit card holders.

Fixed Fee Contract Revenue

Fixed fee contract revenue consists of agreements to provide charter service on a year-round and ad hoc basis. Fixed fee contract revenue is recognized when the transportation is provided.

Other Revenue

Other revenue is generated from leased aircraft, engines, and other miscellaneous sources. Lease revenue is recognized ratably over the lease term.

Accounts Receivable

Accounts receivable, reflected on the accompanying consolidated balance Sheets, primarily consist of amounts due from credit card companies associated with passenger revenue. These receivables are short-term, generally settled within a few days of sale. Bad debt expense, which occurs in the form of credit card chargebacks, was not material in any period presented.


Taxes and Fees

Various taxes and fees, assessed on the sale of tickets to customers, are collected by the Company serving as an agent, and remitted to taxing authorities. These taxes and fees are not included as revenue in the Company’s consolidated statements of income and are recorded as a liability until remitted to the appropriate taxing authority.

Secured Debt

InDuring the first six months of 2017,ended June 30, 2018, the Company borrowed $134.5$10.8 million under a loan agreementsagreement secured by nine Airbus A320 series aircraft.various ground equipment. The notes bear interest at a floatingfixed rate based on LIBOR plus a weighted average margin of 1.684.2 percent and areper year, payable in quarterlymonthly installments over five years.

Senior Secured Revolving Credit Facility

In 2015, the Company, through a wholly owned subsidiary, entered into a senior secured revolving credit facility under which it was entitled to borrow up to $56.0 million. In March 2018, the Company paid off the balance of the facility and amended it to increase the borrowing limit to $81.0 million. The amended facility has a term of 24 months and is based on the value of Airbus A320 Series aircraft which the Company may choose to place in the collateral pool. There was no balance under this facility as of June 30, 2018.

See Note 10, "Subsequent Events," for more information on the revolving credit facility.

General Unsecured Senior Notes

In June 2014, the Company completed an offering of $300.0 million aggregate principal amount of senior unsecured obligations (the "Notes") which will mature in July 2019. In December 2016, the Company completed an offering of an additional $150.0 million principal amount of these notes, which were issued at a price of 101.5 percent of the principal amount, plus accrued interest from July 15, 2016. The Notes bear interest at a rate of 5.5 percent per year, payable in cash semi-annually, on January 15th and July 15th of each year.

The indenture pursuant to which the Notes were issued includes operating and financial restrictions on the Company. These restrictions limit or ten years.restrict, among other things, the Company’s ability and the ability of its restricted subsidiaries to (i) incur additional indebtedness; (ii) incur liens; (iii) make restricted payments (including paying dividends on, redeeming, repurchasing or retiring capital stock); (iv) make investments; and (v) consolidate, merge or sell all or substantially all of its assets. These covenants are subject to various exceptions and qualifications under the terms of the indenture. As of December 31, 2017 and June 30, 2018, the Company exceeded the consolidated total leverage ratio limit, which could affect the ability to make restricted payments in future periods after exhaustion of various exceptions. However, it is not expected that this will have any impact on the restricted payments routinely made in the ordinary course of business. The calculation is made on a quarterly basis based on the trailing 12 months.



Capital Leases

The Company has capital lease obligations related to aircraft, which significantly impacted our recognized assets and liabilities as of June 30, 2018, but did not result in any significant cash receipts or cash payments during the quarter.

Note 45 — Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received by selling an asset or paid to transfer a liability in an orderly transaction between market participants.

Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 inputs that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company uses the market approach valuation technique to determine fair value for investment securities. The assets classified as Level 1 consist of money market funds for which original cost approximates fair value. The assets classified as Level 2 consist of commercial paper, municipal debt securities, federal agency debt securities, US Treasury Bonds, and corporate debt securities, which are valued using quoted market prices or alternative pricing sources including transactions

involving identical or comparable assets and models utilizing market observable inputs. The Company has no investment securities classified as Level 3.

For those assets classified as Level 2 that are not in active markets, the Company obtains fair value from pricing sources using quoted market prices for identical or comparable instruments, and uses pricing models which include all significant observable inputs: maturity dates, issue dates, settlement dates, benchmark yields, reported trades, broker-dealer quotes, issue spreads, benchmark securities, bids, offers and other market related data. These inputs are observable or can be derived from, or corroborated by, observable market data for substantially the full term of the asset.

The fair value of the Company's derivative instrument is determined using standard valuation models. The significant inputs used in these models are readily available in public markets or can be derived from observable market transactions and therefore have been classified as Level 2. Inputs used in these standard valuation models for derivative instruments include the applicable exchange and interest rates.

The fair value of the Company’s publicly held long-term debt is determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets; therefore, the Company has categorized its publicly held debt as Level 2. The remainingRemaining debt agreements areis not publicly held. Theheld, and the Company has determined the estimated fair value of these notes to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable and, therefore, could be sensitive to changes in inputs. The Company utilizes the discounted cash flow method to estimate the fair value of Level 3 debt.

Note 5 — Derivative Instruments

The Company entered into a foreign currency swap in order to mitigate the foreign currency exchange rate risk associated with the forecasted lease revenue from 12 Airbus A320 series aircraft leased to a European carrier until 2018. The Company uses a cash flow hedge to minimize the variability in cash flows of assets, liabilities and forecasted transactions caused by fluctuations in foreign currency exchange rates. For the six months ended June 30, 2017, the net change in fair value recorded in accumulated other comprehensive income related to an unrealized loss on the hedge was $0.6 million compared to $0.3 million for the six months ended June 30, 2016.

At inception, the Company formally designated and documented this financial instrument as a hedge of a specific underlying exposure, the risk management objective, and the strategy for undertaking the hedge transaction. The Company also assessed whether the financial instrument used in the hedging transactions was effective at offsetting changes in either the fair values or cash flows of the related underlying exposures. This assessment is monitored on at least a quarterly basis, and the change in fair market value of any ineffective portion of a financial instrument would be immediately recognized into earnings. For each of the six months ended June 30, 2017 and June 30, 2016, the Company realized $0.5 million in gains from its cash flow hedge into Other revenue. As of June 30, 2017, the Company expects $0.5 million to be reclassified from Other comprehensive income into Other revenue within the next 12 months.

At June 30, 2017, the fair value of the Company's derivative instrument was $0.8 million compared to $1.7 million at December 31, 2016, and is reported in the Company's consolidated balance sheet within deposits and other assets. Refer to Note 4 - Fair Value Measurements for additional information related to the estimated fair value.

Note 6 — Shareholders’ Equity

The Company is authorized by the Board of Directors to acquire up to $100.0 million of its stock through open market purchases under its share repurchase program. As repurchase authority is used, the Board of Directors has, to date, authorized additional expenditures for share repurchases.


Share repurchases consisted of the following during the periods indicated:following:

During the six months ended June 30, 2017,2018, the Company declared and paid recurring cash dividends of $1.40 per share, or $23.2$22.6 million.


Note 7 — Earnings per Share

Basic and diluted earnings per share are computed pursuant to the two-class method. Under this method, the Company attributes net income to two classes: common stock and unvested restricted stock. Unvested restricted stock awards granted to employees under the Company’s Long-Term Incentive Plan are considered participating securities as they receive non-forfeitable rights to cash dividends at the same rate as common stock.

Diluted net income per share is calculated using the more dilutive of the two methods. Under both methods, the exercise of employee stock options is assumed using the treasury stock method. The assumption of vesting of restricted stock, however, differs:

1.Assume vesting of restricted stock using the treasury stock method.

2.Assume unvested restricted stock awards are not vested, and allocate earnings to common shares and unvested restricted stock awards using the two-class method.

For the three and six months ended June 30, 2017,2018, the second method, which assumes unvested awards are not vested, was used in the computation because it was more dilutive than the first method.


The following table sets forth the computation of net income per share, on a basic and diluted basis, for the periods indicated (share count and dollar amounts other than per-share amounts in table are in thousands):

Our operating network asAs of June 30, 20172018, we were operating 413 routes verses 382 as of the same date last year, which represents an 11.78.1 percent increase in the number of routes flown compared to June 30, 2016.increase. Our total numbernumbers of under-servedorigination cities and leisure destinations were 9897 and 20, compared with 95 and 1921 as of June 30, 2017 and 2016, respectively. As of July 14, 2017, we were selling 408 routes.2018.

We also announced Knoxville, Tennessee as our 16th base, with base operations planned to begin in November 2018.

TRENDS

In continuing withAs our fleet transition plan,continues, we added five10 Airbus A320 series aircraft to our operating fleet during the second quarter 2017, including our first two newly manufactured aircraft.of 2018. Airbus aircraft flew 55.476.8 percent of our systemscheduled service ASMs for the quarter, and wecompared to 55.4 percent for the same time period in 2017, which drove a 5.8 percent increase in fuel efficiency (measured as ASMs per gallon). We expect ten11 more Airbus A320 series aircraft to be placed in service by the end of 2017. Average block hours per aircraft has increased by 12.5 percent quarter over quarter due2018 and to increased flying of Airbus aircraft as well as our mix of off-peak flying. Off-peak flying accounted for nearly 29 percent of ASMs forhave fully retired the first two quarters in 2017, versus approximately 26 percent for the same period in 2016.

We retired tworemaining 19 MD-80 aircraft during the quarter and expect to retire eight more MD-80 aircraft and our two remaining Boeing 757-200 aircraft by the end of 2017. Our scheduled MD-80 retirements could be accelerated if unexpected major maintenance were to be needed.2018.

Irregular operations,Although the number of aircraft in our fleet will decline by the end of the year with the retirement of all of our MD-80 aircraft, we intend to continue increasing capacity through higher utilization rates on our Airbus fleet than we have on our MD-80 aircraft. Additionally, our Airbus fleet has more available seats, on average, than our MD-80 fleet. However, our capacity growth through the end of the 2018 year will be lower than in prior years as wella result of our fleet transition.

Unexpected delays in the scheduled delivery timing of used Airbus A320 series aircraft caused operational disruptions during the summer of 2018, as costs necessarythe lack of available aircraft resulted in the reschedule or cancellation of many scheduled service flights. We believe we have been conservative in adding aircraft to our schedule when anticipating future deliveries of aircraft, but delays on certain aircraft deliveries and inductions during second quarter 2018 were unusual and beyond our ability to effectively transitionfully recover our published schedule. In anticipation of known aircraft delivery and induction delays, we removed three lines of flying in late June and July to shore up the integrity of our operations. This will result in a single fleet type, have contributed to increased costsreduced number of flights and reduced revenues during the second quarter 2017. Costs associated with these needs, such as higher pilot staffing levels to supportperiods impacted, but our flight schedule with three separate aircraft types, while continually training additional Airbus pilots to support the growing number of operating Airbus aircraft, will continue until the fleet transition nears completion.completion percentage has improved.

DuringIn April 2018, CBS aired a 60 Minutes segment critical of our safety and the quarter we announced 28 new routesFAA oversight of our operations. We believe the report was misleading, misrepresented our safety culture at that time and now, and mostly ignored the substantial improvement in the reliability of our operations since the events reported. Our customers' reaction to this story appears to have been short-lived and cancellations and bookings returned to normal levels weeks later.

Planning and development for Sunseeker Resorts is ongoing. Construction is expected to begin in the second half of 2017, including service into three new cities - Milwaukee, Wisconsin; Norfolk, Virginia; and Gulfport, Mississippi. As of June 30, 2017, we were offering service on 123 medium-sized city routes compared to 87 as2018, with the opening of the same date in 2016. Our East Coast presence continues to be an area of focus, with 62.3 percent of scheduled service ASMs represented by Eastern markets, and we have commenced seasonal service to Destin, Florida, our newest base.resort planned for 2020.

We have two employee groups which have voted for union representation and with which we have yet to reach agreement - flight attendants and flight dispatchers. These employees make up
In March 2018, our maintenance technicians who represent approximately 31nine percent of our total employee base. base (approximately 340 employees), voted for union representation by the IBT. Negotiations for an agreement with this group are expected to begin in the near future.

In July 2018, the IBT announced that our pilots were supportive of a strike as a result of delays in our implementation of a new preferential bidding system for pilot flight assignments. We do not believe we are in violation of the collective bargaining agreement with our pilots in this regard, nor do we believe the pilots have a legal right to strike because of this issue. As a result, we have filed suit against the IBT seeking to foreclose the possibility of a strike at this time.

Our flight attendant group approved their collective bargaining agreement effective in December 2017.

Any labor actions whether following an inability to reach a collective bargaining agreementsagreement with theseany employee groupsgroup or otherwise could materially impact our operations during the continuance of any such activity. Any labor agreement reached following negotiations would also likely increase our operating costs.

RESULTS OF OPERATIONS

Comparison of three months ended June 30, 20172018 to three months ended June 30, 20162017

Operating Revenue

Scheduled servicePassenger revenue. ScheduledPassenger revenue now includes both scheduled service revenue and air-related ancillary revenue, due to the implementation of the New Revenue Standard. For the second quarter 2018, passenger revenue increased 10.4 percent compared to 2017. The increase was driven primarily by a 10.1 percent increase in scheduled service departures and a 1.0 percentage point increase in load factor, which resulted in 12.7 percent more scheduled service passengers traveling. Additional passengers resulted in quarter-over-quarter increases in ancillary revenue products such as convenience, baggage and seat fees.

Third party products revenue. Third party product revenue for the second quarter 20172018 increased 16.724.4 percent overall compared to 2016. The increase was2017, due primarily driven by a 14.6 percent increase in scheduled service passengers, aided byto an increase in scheduled service average base fare.

Ancillary air-related charges. Ancillary air-related charges for the second quarter 2017 increased 13.0 percent compared to 2016, due mostly to the increase in scheduled service passengers. The increase was slightly diluted by a 1.4 percent decrease in average ancillary air-related fare per passenger which correlates with a 3.1 percent reduction in stage length, as shorter trips tend to produce lower ancillary charges.

Ancillary third party revenue. Ancillary third party revenue increased 19.5 percent for the second quarter 2017 compared to 2016 due to revenue generated from our co-branded credit card program which launched in third quarter 2016. This increase from co-branded credit card revenue was slightly offset by a decrease in net revenue from third party products (hotel rooms,

rental cars, attraction and show tickets) driven by a 7.5 percent and 5.5 percent decrease in hotel room nights and rental car days, respectively. Overall, there was a 4.3 percent increase in ancillary third party revenue per passenger year over year.cars.

Fixed fee contract revenue. Fixed fee contract revenue for the second quarter 2018 decreased 30.6 percent from 2017. This was planned and expected due to less availability of aircraft for charter flying during our fleet transition.

Other revenue. Other revenue decreased $3.5 million for the second quarter 2018 from 2017 increased $4.3 millionprimarily as six aircraft which generated lease revenue from 2016 due mostlya European carrier during the second quarter 2017, had been delivered to increased flying for bothus prior to the Department of Defense and under our Apple Vacations charter.second quarter 2018.

Operating Expenses

We primarily evaluate our expense management by comparing our costs per passenger and per ASM across different periods, which enables us to assess trends in each expense category. The following table presents operating expense per passenger for the indicated periods. The table also presents operating expense per passenger, excluding fuel, a statistic which gives management and investors the ability to measure and monitor our cost performance absent fuel price volatility. Both the cost and availability of fuel are subject to many economic and political factors beyond our control.

Aircraft fuel expense. Aircraft fuel expense increased 42.3$37.1 million, or 43.4 percent, for the second quarter 20172018 compared to 2016. Excluding one-time, $8.3 million fuel tax refunds in the second quarter of 2016, fuel expense would have increased 25.0 percent year over year and2017 as the system average fuel cost per gallon would have increased by 10.3 percent. Additionally, there was39.2 percent, coupled with a 12.93.3 percent increase in system fuel gallons consumed on a 9.4 percent increase in system ASMs. ASM growth outpaced fuel consumption as fuel efficiency (measured as ASMs per gallon) increased 5.8 percent year over year due to an increase in total system capacity of 12.7 percent.increased flying on our Airbus aircraft which are more fuel efficient than our MD-80 aircraft.


Salary and benefits expense. Salary and benefits expense increased $23.7$9.4 million, or 34.510.2 percent, for the second quarter 20172018 when compared to the same period last year. The increase is largely attributable to $16.8 milliona 5.8 percent increase in incremental expense related tofull-time equivalent employees. Additionally, in conjunction with the collective bargaining agreement with our pilots, whichflight attendants that went into effect in August 2016, as well as costs associated with a 12.4 percent increase in the number of full-time equivalent employees needed to support additional operating aircraft and the transition to a single fleet type. Additionally, stock compensationDecember 2017, flight attendant total salaries expense increased incrementally by $1.9 million relatedan average of 25 percent compared to management equity grants which were not in place in second quarter 2016.2017.

Station operations expense. Station operations expense for the second quarter 20172018 increased 17.06.6 percent on a 17.010.1 percent increase in scheduled service departures compared to the same period in 2016.2017.

Maintenance and repairs expense. Maintenance and repairs expense for the second quarter 20172018 decreased 2.1$4.0 million, or 14.1 percent, compared to the same period in 2016. This2017. The year-over-year decrease is mostlylargely due to a decrease in majorfewer heavy maintenance expense forevents performed on our MD-80 aircraft, as there was a higher numberthey are being systematically retired from our operating fleet. Additionally, the cost of events in the prior year because the number of MD-80 aircraft in service was higher in the second quarter 2016. This decrease was partially offset by an increase in expenses related to parts repairs and routinemajor maintenance in the current quarter. We expect routine maintenance expensesevents for our used Airbus aircraft to increase over time as repair costs foris deferred in accordance with the deferral method of accounting and the amortization of these aircraft are generally more expensive than similar maintenance for our MD-80 aircraft.expenses is included in depreciation and amortization expense.

Depreciation and amortization expense. Depreciation and amortization expense for the second quarter 2017 increased 18.62018 remained relatively flat, with a 1.0 percent compareddecrease year over year. The decrease is due to 2016. Depreciation expense for the remainder of 2017 will continue to outpace 2016 as retirement ofimpairment charge taken on our MD-80 aircraft has been acceleratedin the fourth quarter 2017 as no depreciation expense for this fleet remains in the current quarter. Depreciation expense

related to 2019 or earlier. We alsothe MD-80 aircraft and Boeing 757-200 aircraft (retired in late 2017) for the three months ended June 30, 2017 was $4.9 million and $1.4 million, respectively.

The decrease in total depreciation and amortization expense was offset by higher monthly depreciation expense associated with our Airbus aircraft, as we continue to add Airbus aircraft into service which resultservice. Depreciation expense for this fleet was $19.8 million for the second quarter 2018 compared to $13.7 million for the same period in higher incremental monthly depreciation expense than our MD-80s.2017. Amortization of major maintenance costs under the deferral method of accounting for the Airbus aircraft was $2.6 million for the second quarter 2018 compared to $1.6 million for the second quarter 2017.

Sales and marketing expense. Sales and marketing expense for the second quarter 20172018 increased $7.5$4.9 million compared to the same period in 2016, mostly2017, partly due to an increase in net credit card fees paid by us. We previously charged for credit card fee reimbursement (a fee charged to customers for using a credit card) at zero margin, which was applied as a reduction to sales and marketing expense, and the net amount paid by us for credit card fees was reduced. We discontinued the charge for credit card fee reimbursement in January 2017, although this charge still applies to travel booked up to the discontinuation date. Credit card fee reimbursements for the second quarter (which were recorded as reductions of sales and marketing expense) declined to $0.6 million from $6.3 million in the second quarter 2016, accounting for the majorityresult of the 10.4 percent increase in this line itempassenger revenue year over year. There were also increased expenses related to various marketing initiatives, including our national ad campaign, for our growing network.

We do not currently have operating aircraft under lease.

Other operating expense. Other operating expense for the second quarter 2017 increased $6.5 million compared to 2016. The increase in expense is due to increased flight crew training needed to support our growing operating fleet and network, as well as losses taken on the disposal of assets.leases.

Income Tax Expense

While we expect our tax rate to be fairly consistent in the near term, it will vary depending on recurring items such as the amount of income we earn in each state and the state tax rate applicable to such income. Discrete items during interim periods may also affect our tax rates.

Scheduled service revenue. Scheduled service revenue for the six months ended June 30, 2017 increased 10.7 percent compared with 2016. The increase was mostly the result of a 12.8 percent increase in scheduled service passengers offset by a 1.8 percent decrease in scheduled service average base fare, which was affected by a 24.2 percent increase in off-peak capacity period over period.
Ancillary air-related charges. Ancillary air-related charges for the six months ended June 30, 2017 increased 10.9 percent compared with 2016 due mostly to the increase in scheduled service passengers. These effects were diluted by a 1.7 percent decrease in ancillary air-related charges per passenger as items such as bag fees tend to decrease in correlation with a shorter stage length and lower base fare.

Ancillary third party revenue. Ancillary third party revenue for the six months ended June 30, 2017 increased $3.8 million over the same period in 2016 due to revenue generated from our co-branded credit card program which launched in third quarter 2016. This increase from co-branded credit card revenue was slightly offset by a decrease in net revenue from third party products (hotel rooms, rental cars, attraction and show tickets), partially driven by a 5.4 percent decrease in hotel room nights. Overall, there was a 3.0 percent increase in ancillary third party revenue per passenger year over year.

Fixed fee contract revenue. Fixed fee contract revenue for the six months ended June 30, 2017 increased $8.8 million compared with 2016, due to increased flying for both the Department of Defense and under our Apple Vacations charter.

Aircraft fuel expense. Aircraft fuel expense increased 49.6 percent for the six months ended June 30, 2017 compared to the same period in 2016. Excluding the effect of one-time $8.3 million in fuel tax refunds in the second quarter 2016, fuel expense would have increased 39.4 percent and the system average fuel cost per gallon would have increased by 23.9 percent. Additionally, there was a 12.9 percent increase in system fuel gallons consumed due to an increase in total system capacity of 12.6 percent.
Salary and benefits expense. Salary and benefits expense increased $50.8 million or 36.8 percent for the six months ended June 30, 2017 compared to the same period in 2016. The increase is largely attributable to $31.0 million in incremental expense related to the collective bargaining agreement with our pilots, which went into effect in August 2016, as well as costs associated with a 12.4 percent increase in the number of full-time equivalent employees needed to support additional operating aircraft and the transition to a single fleet type. Additionally, stock compensation expense increased incrementally by $4.4 million related to management equity grants which were not in place in the first half of 2016.
Station operations expense. Station operations expense for the six months ended June 30, 2017 increased 10.6 percent on a 17.0 percent increase in scheduled service departures compared to the same period in 2016. Decreases in various supplementary station expenses contributed to growth in departures outpacing the increase in expense.

Maintenance and repairs expense. Maintenance and repairs expense for the six months ended June 30, 2017 increased 5.4 percent compared with the same period in 2016, due primarily to a 2.4 percent increase in average number of aircraft in service as well as incremental expenses related to parts repairs and routine maintenance on our Airbus aircraft. We expect routine maintenance expenses for our used Airbus aircraft to increase over time as repair costs for these aircraft are generally more expensive than similar maintenance for our MD-80 aircraft.
Depreciation and amortization expense. Depreciation and amortization expense for the six months ended June 30, 2017 increased by 21.2 percent, compared to the same period in 2016. Depreciation expense for the remainder of 2017 will continue to outpace 2016 as retirement of our MD-80 aircraft has been accelerated to 2019 or earlier. We have also added ten Airbus aircraft into service as of June 30, 2017 when compared to the same date in 2016, which results in higher incremental monthly depreciation expense than our MD-80s. Additionally, this expense was affected by major maintenance amortization for our Airbus aircraft in accordance with the deferral method of accounting. Prior to June 2016, we had not incurred any major maintenance costs on our Airbus aircraft.
Sales and marketing expense. Sales and marketing expense for the six months ended June 30, 2017 increased $11.7 million compared to the same period in 2016, mostly due to an increase in net credit card fees paid by us. We previously charged for credit card fee reimbursement (a fee charged to customers for using a credit card) at zero margin, which was applied as a reduction to sales and marketing expense, and the net amount paid by us for credit card fees was reduced. We discontinued the charge for credit card fee reimbursement in January 2017, although this charge still applies to travel booked up to the discontinuation date. Consequently, credit card fee reimbursements for the first half of 2017 (which were recorded as reductions of sales and marketing expense) declined to $4.0 million from $13.2 million in the first half of 2016. There were also year-over-year increased expenses related to various marketing initiatives for our growing network.

Aircraft lease rentals expense. Aircraft lease rentals expense for the six months ended June 30, 2017 increased $2.1 million compared to the same period in 2016 due to additional subservice flights needed for irregular operations in the second quarter 2017. We do not currently have operating aircraft under lease.

Other expense. Other operating expense for the six months ended June 30, 2017 increased $9.2 million compared to 2016. The increase is partially due to losses recorded on disposed aircraft parts in 2017 compared to a gain of over $2.0 million recorded on an engine sale in 2016. Additionally, property taxes on higher asset amounts, and expenses related to crew training in 2017 to support our fleet transition and network growth, also increased year over year.

Income Tax Expense

Our effective tax rate remained flat at 37.6 percent for each of the six months ended June 30, 2017 and 2016. The effective tax rate for the sixthree months ended June 30, 20172018 differed from the statutory federal income tax rate of 35.021.0 percent primarily due to executive compensation deduction limitations as well asthe tax benefit from dissolution of foreign subsidiaries, offset by state and foreign taxes. While we expect our tax rate to be fairly consistent in the near term, it will vary depending on recurring items such as the amount of income we earn in each state and the state tax rate applicable to such income. Discrete items during interim periods may also affect our tax rates.




Comparison of six months ended June 30, 2018 to six months ended June 30, 2017
Operating Revenue

Passenger revenue. Passenger revenue now includes both scheduled service revenue and air-related ancillary revenue, due to the implementation of the New Revenue Standard. For the six months ended June 30, 2018, passenger revenue increased 12.2 percent compared with 2017. The increase was mostly attributable to a 9.8 percent increase in scheduled service departures and a 1.9 percentage point increase in load factor, which resulted in 13.9 percent more scheduled service passengers traveling. Additional passengers resulted in year-to-date increases in ancillary revenue products such as convenience, baggage and seat fees.
Third party products revenue. Third party products revenue for the six months ended June 30, 2018 increased 4.0 percent over the same period in 2017 primarily due to an increase in net revenue from rental cars. This was offset by revenue reclassifications related to our Allegiant World Mastercard® co-brand credit card, whereby $3.6 million of the revenue related to the travel component was reclassified into passenger revenue.

Fixed fee contract revenue. Fixed fee contract revenue for the six months ended June 30, 2018 decreased 18.3 percent compared with 2017. This was planned and expected due to less availability of aircraft for charter flying during our fleet transition.

Other revenue. Other revenue decreased $3.9 million for the six months ended June 30, 2018 compared to 2017 primarily as six aircraft which generated lease revenue from a European carrier during the six months ended June 30, 2017 were delivered to us during the six months ended June 30, 2018. The effects of this decrease were slightly offset by increases in revenue from our golf course management solution.

Aircraft fuel expense. Aircraft fuel expense increased $58.4 million, or 34.4 percent, for the six months ended June 30, 2018 compared to the same period in 2017 as the system average fuel cost per gallon increased by 29.5 percent, coupled with a 3.6 percent increase in system fuel gallons consumed on a 9.9 percent increase in system ASMs. ASM growth outpaced fuel consumption as fuel efficiency (measured as ASMs per gallon) increased 6.1 percent year over year, due to increased flying on our Airbus aircraft which are more fuel efficient than our MD-80 aircraft.
Salary and benefits expense. Salary and benefits expense increased $26.1 million, or 13.8 percent, for the six months ended June 30, 2018 compared to the same period in 2017. The increase is largely attributable to a 5.8 percent increase in the number of full-time equivalent employees. Additionally, in conjunction with the collective bargaining agreement with our flight attendants that went into effect in December 2017, flight attendant total salaries expense increased an average of 21 percent year over year.
Station operations expense. Station operations expense for the six months ended June 30, 2018 increased 11.7 percent on a 9.8 percent increase in scheduled service departures compared to the same period in 2017. The increase in expense outpaced the increase in departures due primarily to certain station incentives which expired during the first quarter of 2018.

Maintenance and repairs expense. Maintenance and repairs expense for the six months ended June 30, 2018 decreased $14.9 million, or 25.3 percent, compared with the same period in 2017. The year-over-year decrease is largely due to fewer heavy maintenance events performed on our MD-80 series aircraft, as they are being systematically retired from our operating fleet. Additionally, the cost of major maintenance events for our Airbus aircraft is deferred in accordance with the deferral method of accounting and the amortization of these expenses is included under depreciation and amortization expense.
Depreciation and amortization expense. Depreciation and amortization expense for the six months ended June 30, 2018 decreased by 4.4 percent compared to the same period in 2017, partially due to the impairment charge taken on our MD-80 aircraft in the fourth quarter 2017 as no depreciation expense for this fleet remains in the current year. Depreciation expense related to the MD-80 aircraft and Boeing 757-200 aircraft (retired in late-2017) for the six months ended June 30, 2017 was $11.3 million and $2.9 million, respectively.
The decrease in depreciation and amortization expense was partially offset by higher monthly depreciation expense associated with our Airbus aircraft, as we continue to add Airbus aircraft into service. Depreciation expense for this fleet was $38.0 million for the six months ended June 30, 2018 compared to $26.5 million for the same period in 2017. Amortization of major maintenance costs under the deferral method of accounting for the Airbus aircraft was $5.1 million for the six months ended June 30, 2018 compared to $2.9 million for 2017.

Sales and marketing expense. Sales and marketing expense for the six months ended June 30, 2018 increased $10.6 million compared to the same period in 2017, partly due to an increase in net credit card fees paid as a result of a 12.2 percent increase in passenger revenue year over year. There were also increased expenses related to various marketing initiatives, including our national ad campaign, for our growing network.
Aircraft lease rentals expense. Aircraft lease rentals expense for the six months ended June 30, 2018 decreased $2.5 million compared to the same period in 2017 due to fewer sub-service flights in the current year. We do not currently have aircraft under operating leases.

Other expense. Other operating expense for the six months ended June 30, 2018 increased $2.3 million compared to 2017. The increase is primarily due to information technology expenses, as well as other administrative expenses incurred to support our airline operations and golf course management business.
Income Tax Expense

Our effective tax rate was 20.6 percent for the six months ended June 30, 2018, compared to 37.3 percent for the six months ended June 30, 2017. The effective tax rate for the six months ended June 30, 2018 differed from the statutory federal income tax rate of 21.0 percent primarily due to the tax benefit from dissolution of foreign subsidiaries, offset by state taxes. While we expect our tax rate to be fairly consistent in the near term, it will vary depending on recurring items such as the amount of income we earn in each state and the state tax rate applicable to such income. Discrete items during interim periods may also affect our tax rates.

LIQUIDITY AND CAPITAL RESOURCES

Current liquidity

Cash, restricted cash and investment securities (short-term and long-term) increaseddecreased from $470.5$501.9 million at December 31, 20162017 to $514.3$441.8 million at June 30, 2017.2018. Restricted cash represents escrowed funds under fixed fee contracts and cash collateral against letters of credit required by hotel properties for guaranteed room availability, airports and certain other parties. Under our fixed fee flying contracts, we require our customers to prepay for flights to be provided by us. The prepayments are escrowed until the flight is completed and are recorded as restricted cash with a corresponding amount as air traffic liability. Investment securities represent highly liquid marketable securities which are available-for-sale.

During the first six months of 2017,2018, our primary source of funds was $263.1$283.2 million generated by operations as well as $134.5 million in proceeds from long-term debt issuance.operations. Our operating cash flows and previous borrowings have allowed us to invest in our fleet transition and return capital to shareholders. Our future capital needs are primarily for the acquisition of additional aircraft, including our existing Airbus A320 series aircraft commitments, as well as planned capital outlay related to Sunseeker Resorts and other travel and leisure initiatives. Of the 11 aircraft expected to be placed into service during the remainder of 2018, three are structured as capital leases and will not require separate financing, and one has already been paid for (the aircraft being returned from lease to a European carrier).

We believe we have more than adequate liquidity resources through our operating cash flows, borrowings, and cash balances, to meet our future contractual obligations, and expect to finance a significant portion of the purchase price of our newly manufactured Airbus aircraft order on acceptable terms. Weobligations. In addition, we continue to consider raising funds through debt financing on an opportunistic basis.

In addition to our recurring quarterly cash dividend, we plan to continue repurchasing our stock in the open market subject to availability of cash resources and compliance with our debt covenants. In July 2017, our board of directors replenished ourcurrent share repurchase authority to a total ofis $100 million. There is no expiration to this program.

Debt

Our long-term debt and capital lease obligations balance, without reduction for related issuance costs, increaseddecreased from $813.2 million$1.2 billion as of December 31, 20162017 to $882.4 million$1.1 billion as of June 30, 20172018 as we borrowed additional fundspaid off our senior secured by aircraft whilerevolving credit facility and continued making scheduled repayments on our existing debt.debt, including the prepayment of certain debt secured by Airbus A320 series aircraft. During the second quarter 2017of 2018, we borrowed $112.5$10.8 million secured by seven aircraft.various ground equipment.

Sources and Uses of Cash

Operating Activities. During the six months ended June 30, 2017,2018, our operating activities provided $263.1$283.2 million of cash compared to $256.1$262.9 million during the same period of 2016.2017. The year-over-year increase in cash inflows is the result of a $13.8 million increase in net income, as well as changes in various asset and liability accounts, including a $46.9 million decrease in accounts receivable. This was primarily impactedoffset by adjustments made for non-cash items such as deferred income taxes as well as a decrease($26.9 million lower in accounts receivable, which offset the effects of lower net income for the six months ended June 30, 2017.2018).

Operating cash inflows are primarily derived from providing air transportation and related ancillary products and services to customers, and we expect to use that cash flow to purchase aircraft and equipment, make scheduled debt payments, invest in Sunseeker and other travel and leisure initiatives, and return capital to shareholders through share repurchases and dividends. 

Investing Activities. Cash used in investing activities was $269.5$158.6 million during the six months ended June 30, 20172018 compared to $118.9$269.5 million for the same period in 2016.2017. The year-over-year increasedecrease is mostly due primarily to $182.3 million in property and equipment purchases and pre-delivery deposits compared to $105.2investment security activity, as cash proceeds from maturities of investment securities (net of purchases) were $30.4 million in the same periodfirst half of 2016. Additionally, our net2018 compared to cash used to purchase investment securities (net of proceeds from maturities) wasproceeds) of $88.6 million during the first six months of 2017 compared to $17.5 million for the same period in 2016.2017. Cash used to purchase property and equipment (including pre-delivery deposits) was $187.5 million for the first six months of 2018 compared to $182.3 million in the same period of 2017.

Financing Activities. Cash used in financing activities for the six months ended June 30, 20172018 was $38.3$153.1 million compared to $118.6$38.3 million for the same period in 2016. During2017. The year-over-year increase is primarily due to an increase in principal payments on long-term debt and capital lease obligations, as we paid $142.4 million in debt and capital lease payments in the first half of 2018 compared to $64.9 million for the same period in 2017. Our debt payments in the first half of 2018 included various scheduled balloon payments, as well as the payoff of our senior secured revolving credit facility, which had $41.6 million in outstanding principal as of December 31, 2017. Additionally, we received $10.8 million in loan proceeds during the second quarter 2018, compared to $134.5 million in loan proceeds during the same period in 2017. For the six months ended June 30,

2018, we paid cash dividends of 2017, we repurchased common stock for $84.9$22.6 million, and paidcompared to the payment of cash dividends of $23.2 million compared to the repurchase ofand $86.2 million in open market common stock repurchases for $63.3 million and payment of cash dividends of $44.4 million ($27.7 million of which was a special dividend declared in December 2015) in the same period of 2016. These uses were offset by proceeds from the issuance of debt net of principal payments of $69.7 million in 2017, while principal payments exceeded proceeds from issuance of debt by $11.2 million in the same period of 2016.2017.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

A descriptionExcept as discussed below relating to the New Revenue Standard, in the second quarter of 2018, there were no changes to our critical accounting policies and estimates from those disclosed in the Consolidated Financial Statements and accompanying notes contained in our 2017 Form 10-K.

Effective January 1, 2018, we adopted the New Revenue Standard using the full retrospective method, which resulted in the recast of the 2017 prior period data presented. Under this ASU and subsequently issued amendments, revenue is included in Item 7 of our Annual Report on Form 10-Krecognized at the time a good or service is transferred to a customer for the year ended December 31, 2016. There has been no material change to these policies during the six months ended June 30, 2017.amount of consideration received.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are subject to certain market risks, including commodity prices (specifically aircraft fuel). The adverse effects of changes in these markets could pose potential losses as discussed below. The sensitivity analysis provided does not consider the effects that such adverse changes may have on overall economic activity, nor does it consider additional actions we may take to mitigate our exposure to such changes. Actual results may differ.

Aircraft Fuel

Our results of operations can be significantly impacted by changes in the price and availability of aircraft fuel, as aircraft fuel expense represented 27.532.3 percent of our operating expenses for the six months ended June 30, 2017.2018. Increases in fuel prices, or a shortage of supply, could have a material impact on our operations and operating results. Based on our fuel consumption for the three and six months ended June 30, 2017,2018, a hypothetical ten percent increase in the average price per gallon of fuel would have increased fuel expense by approximately $8.3$12.0 million and $17.6$22.9 million, respectively. We have not hedged fuel price risk in recentfor many years.


Interest Rates

We have market risk associated with changing interest rates due to the short-term nature of our cash and investment securities and variable-rate debt. We invest available cash in government and corporate debt securities, investment grade commercial paper, and other highly rated financial instruments. Because of the short-term nature of these investments, the returns earned closely parallel short-term floating interest rates. A hypothetical 100 basis point change in interest rates for the six months ended June 30, 2018 would have impacted interest income from cash and investment securities by approximately $2.3 million.

As of June 30, 2017,2018, we had a total of $414.7$563.1 million in variable-rate debt, including current maturities and without reduction for related costs. A hypothetical 100 basis point change in market interest rates for the six months ended June 30, 2017,2018, would have affected interest expense by $1.9approximately $3.2 million.

As of June 30, 2017,2018, we had $467.7$477.1 million of fixed-rate debt, including current maturities and without reduction for related costs, which had a fair value of $484.9 million.costs. A hypothetical 100 basis point change in market interest rates would not impact interest expense or have a material effect on the fair value of our fixed-ratefixed rate debt instruments as of such date.

See Item 7A "Quantitative and Qualitative Disclosures About Market Risk" in the Company's Annual Report on Form 10-K for the year ended December 31, 2016,2017, for further information about market risk.

Item 4. Controls and Procedures

As of June 30, 2017,2018, under the supervision and with the participation of our management, including our chief executive officer (“CEO”("CEO") and chief financial officer (“CFO”), we evaluated the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the “Exchange Act.”Act”) as of the end of the period covered by this report. Based on thisthat evaluation, management, including our managementCEO and CFO, has concluded that our disclosure controls and procedures are designed, and are effective, to give reasonable assurance that the information we are required to disclose is recorded, processed, summarized and reported within the time periods specified in

the SEC’s rules and forms. Based upon this evaluation, management concluded that our disclosure controlsforms and procedures are effective in providing reasonable assurance that information required to be disclosed in our reports filed with the SEC under the Exchange Act is accumulated and communicated to the Company’s management, including the CEO and the CFO, as appropriate to allow timely decisions regarding required disclosure.

There were no changes in our internal control over financial reporting that occurred during the quarter ending June 30, 2017,2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Effective January 1, 2018, we adopted Accounting Standards Codification 606, “Revenue from Contracts with Customers.” Although the New Revenue Standard is not expected to have a material impact on our ongoing net income, changes were made to relevant business processes and the related control activities, including information systems, in order to monitor and maintain appropriate controls over financial reporting. The operating effectiveness of these changes will be evaluated as part of our annual assessment on the effectiveness of internal controls over financial reporting.
