See accompanying notes to consolidated financial statements. UAL Corporation and Subsidiary Companies Notes to Consolidated Financial Statements (Unaudited) The Company - ----------- UAL Corporation ("UAL") is a holding company whose principal subsidiary is United Air Lines, Inc. ("United"). Interim Financial Statements - ---------------------------- The consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to or as permitted by such rules and regulations, although UAL believes that the disclosures are adequate to make the information presented not misleading. In management's opinion, all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the results of operations for the three month periods have been made. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in UAL's Annual Report on Form 10-K for the year 1996. Employee Stock Ownership Plans - ------------------------------ Pursuant to amended labor agreements which provide for wage and benefit reductions and work-rule changes which commenced July 1994, UAL has agreed to issue convertible preferred stock to employees. Note 2 of the Notes to Consolidated Financial Statements in the 1996 Annual Report on Form 10-K contains additional discussion of the agreements, stock to be issued to employees and the related accounting treatment. Shares earned in 1996 were allocated in March 1997 as follows: 190,307 shares of Class 2 ESOP Preferred Stock were contributed to the Non-Leveraged ESOP and an additional 537,917 shares were allocated in "book entry" form under the Supplemental Plan. Also, 2,345,745 shares of Class 1 ESOP Preferred Stock were allocated under the Leveraged ESOP. Finally, an additional 768,493 shares of Class 1 and Class 2 ESOP Preferred Stock have been committed to be released by the Company since January 1, 1997. Income Taxes - ------------ The provisions for income taxes are based on the estimated annual effective tax rate, which differs from the federal statutory rate of 35% principally due to state income taxes and certain nondeductible expenses. Deferred tax assets are recognized based upon UAL's history of operating earnings and expectations for future taxable income. Per Share Amounts - ----------------- During the first quarter of 1996, UAL repurchased 843,210 depositary shares, representing 843 shares of its Series B 12 1/4% preferred stock at an aggregate cost of $27 million. These transactions had no effect on earnings; however, the difference of $6 million between the cash paid and the carrying value of the preferred stock acquired is included in the computation of earnings per share. Per share amounts were calculated after providing for dividends on preferred stock, including ESOP convertible preferred stock, of $19 and $16 million, respectively, in the 1997 and 1996 first quarters. Per share amounts for the 1997 first quarter were based on weighted average common shares and common stock equivalents outstanding, including ESOP shares committed to be released. Common stock equivalents were not included in the 1996 first quarter computations as they did not have a dilutive effect. In February 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share," which establishes standards for computing and reporting earnings per share. SFAS No. 128 is effective for periods ending after December 15, 1997; earlier application is not permitted. Restatement of all prior-period earnings per share data is required. On a pro forma basis, first quarter 1997 earnings per share would be as follows: Basic Earnings Per Share $ 1.45 Diluted Earnings Per Share $ 0.92 Prepayment of Long-Term Obligations - ----------------------------------- On March 7, 1997, Air Wis Services, Inc. ("Air Wis"), a wholly owned subsidiary of UAL, issued a notice of redemption for all of its outstanding 7 3/4% convertible subordinated debentures, due 2010. On April 8, $16 million of debentures outstanding were redeemed at 100% of the principal amount plus accrued interest. The debentures have been reclassified to current long-term debt at March 31. In the first quarter of 1996, UAL repaid prior to maturity $242 million in principal amount of various debt securities, resulting in an aggregate extraordinary loss of $29 million, after a tax benefit of $18 million. The securities were scheduled for repayment periodically through 2021. Contingencies and Commitments - ----------------------------- UAL has certain contingencies resulting from litigation and claims (including environmental issues) incident to the ordinary course of business. Management believes, after considering a number of factors, including (but not limited to) the views of legal counsel, the nature of contingencies to which UAL is subject and its prior experience, that the ultimate disposition of these contingencies is not expected to materially affect UAL's consolidated financial position or results of operations. At March 31, 1997, commitments for the purchase of property and equipment, principally aircraft, approximated $6.7 billion, after deducting advance payments. An estimated $2.6 billion will be spent during the remainder of 1997, $2.0 billion in 1998, $1.0 billion in 1999 and $1.1 billion in 2000 and thereafter. The above amounts reflect firm orders for 18 B777 aircraft, 21 B747 aircraft, 6 B757 aircraft, 16 A320 aircraft and 28 A319 aircraft to be delivered through 2002. However, these amounts do not include a recent order for an additional three B747 aircraft which are scheduled to be delivered in 1999. Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS LIQUIDITY AND CAPITAL RESOURCES UAL's total of cash and cash equivalents and short- term investments was $957 million at March 31, 1997, compared to $697 million at December 31, 1996. Cash flows from operating activities amounted to $680 million. Financing activities included principal payments under debt and capital lease obligations of $13 million and $59 million, respectively, and deposits of an equivalent $56 million in Japanese yen with certain banks in connection with the financing of certain capital lease transactions. In the first quarter of 1997, United took delivery of one A320 aircraft and two B777 aircraft. The A320 aircraft was purchased and the B777s were acquired under capital leases. Property additions, including the A320 and aircraft spare parts, amounted to $308 million. Property dispositions resulted in proceeds of $14 million. At March 31, 1997, commitments for the purchase of property and equipment, principally aircraft, approximated $6.7 billion, after deducting advance payments. An estimated $2.6 billion will be spent during the remainder of 1997, $2.0 billion in 1998, $1.0 billion in 1999 and $1.1 billion in 2000 and thereafter. The above amounts reflect firm orders for 18 B777 aircraft, 21 B747 aircraft, 6 B757 aircraft, 16 A320 aircraft and 28 A319 aircraft to be delivered through 2002. However, these amounts do not include a recent order for an additional three B747 aircraft which are scheduled to be delivered in 1999. Funds necessary to finance aircraft acquisitions are expected to be obtained from internally generated funds, irrevocable external financing arrangements or other external sources. In April 1997, Standard & Poor's raised its credit rating on United's senior unsecured debt to BB+ from BB and raised its credit rating on UAL's Series B preferred stock and redeemable preferred securities to BB- from B+. RESULTS OF OPERATIONS UAL's results of operations for interim periods are not necessarily indicative of those for an entire year, as a result of seasonal factors to which United is subject. First and fourth quarter results are normally affected by reduced travel demand in the fall and winter and United's operations, particularly at its Chicago and Denver hubs and at certain east coast cities, are adversely affected by winter weather on occasion. The results of operations in the airline business historically fluctuate significantly in response to general economic conditions. This is because small fluctuations in yield (passenger revenue per revenue passenger mile) and cost per available seat mile can have a significant effect on operating results. UAL anticipates industrywide fare levels, capacity growth, low-cost competition, general economic conditions, labor and fuel costs, taxes, U.S. and international governmental policies and other factors will continue to affect its operating results. Summary of Results ------------------ UAL's earnings from operations were $194 million in the first quarter of 1997, compared to operating earnings of $62 million in the first quarter of 1996. UAL had net earnings in the 1997 first quarter of $105 million ($0.92 per share), compared to a net loss of $23 million in the same period of 1996 (a loss of $0.90 per share). The 1996 first quarter results include an extraordinary loss of $29 million ($0.58 per share) on early extinguishment of debt. The per share amounts for the 1996 first quarter include the effects on equity of the repurchase of Series B preferred stock. See "Per Share Amounts" in the notes to consolidated financial statements. Management believes that a more complete understanding of UAL's results can be gained by viewing them on a pro forma, "fully distributed" basis. This approach considers all ESOP shares which will ultimately be distributed to employees throughout the ESOP (rather than just the shares committed to be released) to be immediately outstanding and thus fully distributed. Consistent with this method, the ESOP compensation expense is excluded from fully distributed net earnings and ESOP convertible preferred stock dividends are not deducted from earnings attributable to common stockholders. On a fully distributed basis, UAL's net earnings for the 1997 first quarter would have been $215 million ($1.61 per share) compared to $105 million ($0.92 per share) as reported under generally accepted accounting principles. For the first quarter of 1996, fully distributed net earnings would have been $76 million ($0.50 per share) compared to a loss of $23 million (loss of $0.90 per share) as reported under generally accepted accounting principles. No adjustments are made to fully distributed earnings to take into account future salary increases. Specific factors affecting UAL's consolidated operations for the first quarter of 1997 are described below. First Quarter 1997 Compared with First Quarter 1996. ---------------------------------------------------- Operating revenues increased $386 million (10%). United's revenue per available seat mile increased 7% to 10.19 cents. Passenger revenues increased $348 million (11%) due to a 5% increase in yield to 12.80 cents and a 5% increase in revenue passenger miles. The Company believes that passenger revenues benefited by approximately $25 million due to the threat of a labor strike at a major competitor. The following analysis by market is based on information reported to the U.S. Department of Transportation: Latin America revenue passenger miles increased 7% over the same period last year, with a 13% increase in yield largely due to the strengthening Latin America economy. Atlantic revenue passenger miles increased 11% and yield increased nearly 5% for the period. In the Pacific, revenue passenger miles increased 3% and yield increased 1% from the same period last year. Pacific yields continue to be negatively impacted by the weakness of the Japanese yen to the dollar. Domestic revenue passenger miles increased 5% with a 6% increase in yield. The increase in domestic yield is a result of a strong market industry-wide coupled with continued success in attracting a better mix of higher-yield business travelers. Available seat miles increased 4% systemwide, reflecting increases of 13% in the Atlantic, 1% in the Pacific and 4% on Domestic routes, offset by a decrease of 4% in Latin America. The system passenger load factor increased 1.2 points to 69.9%. Cargo revenues increased $20 million (11%) as freight revenues increased 13% and mail revenues increased 9%. Cargo yield decreased 2% from the same period last year. Other operating revenues increased $18 million (6%) due to increases in Mileage Plus partner-related revenues and fuel sales to third parties. Operating expenses increased $254 million (7%) and United's cost per available seat mile increased 3%, from 8.98 cents to 9.27 cents. ESOP compensation expense increased $21 million (13%), reflecting a higher average common stock price in 1997. Aircraft fuel expense increased $80 million (17%) due to a 2% increase in consumption and a 15% increase in the average price per gallon of fuel to 78.3 cents. Without the increases in ESOP compensation expense and aircraft fuel, United's cost per available seat mile would have increased 2%. Salaries and related costs increased $71 million (6%) due mainly to increased staffing in certain customer-oriented positions. Landing fees and other rent increased $12 million (6%) due to increased landing fees and facilities rent at various airports. Purchased services increased $31 million (11%) due principally to volume-related increases in computer reservations fees and credit card discounts. Aircraft maintenance increased $26 million (23%) due to increased purchased maintenance, as well as the timing of maintenance cycles. Commissions increased $27 million (8%) due primarily to increased commissionable revenues. Depreciation and amortization decreased $13 million (7%) due to lower depreciation on DC10-10 aircraft, which are being exchanged for B727 hushkits. Other expense amounted to $23 million in the first quarter of 1997 compared to $52 million in the first quarter of 1996. Interest expense decreased $16 million (19%) due to the prepayment of long-term debt in 1996. Interest capitalized, primarily on aircraft advance payments, increased $9 million (60%). Interest income decreased $6 million (33%) due to lower investment balances. Equity in earnings of affiliates increased $5 million (25%) due primarily to higher earnings from the Galileo International Partnership resulting from increased booking revenues. Included in "Miscellaneous, net" in the 1997 and 1996 first quarters were foreign exchange losses of $5 million and $6 million, respectively. LABOR AGREEMENTS AND WAGE ADJUSTMENTS Both the Air Line Pilots Association, International ("ALPA") and the International Association of Machinists and Aerospace Workers ("IAM") ratified previously announced mid- term wage adjustments. Included in the agreements are a 5% increase to wage rates for each union group in July 1997 and a second 5% increase in July 1998. Further, the agreement with ALPA calls for a corresponding 5% increase in both 1997 and 1998 to "book rates" (book rates are used to compute certain other employee benefits), and the agreement with the IAM provides for lump sum payments for all IAM employees and increases in hourly license premium and skill pay for mechanics. These agreements also provide for restoration of wage rates for the two groups in the year 2000 to levels that existed prior to the recapitalization in July 1994, as well as restoration of the Company's contribution to the pilots defined contribution plan from its current rate of 1% to its pre-ESOP rate of 9% in the year 2000. In March, the Company also announced the details of mid-term wage adjustments for non-union United States salaried and management employees. Salaried employees will receive a 5% increase in both July 1997 and July 1998, as well as a lump-sum payment in July 1997. Management employees will receive a 4% increase in both July 1997 and July 1998, and management employees not participating in the Company's Incentive Compensation Plan will participate in a three-year profit-sharing plan that could pay an additional amount in 1998, 1999 and 2000, if the Company meets specific pre-tax earnings objectives in 1997, 1998 and 1999, respectively. The cost to the Company in 1997 for these wage and benefit adjustments is approximately $120 million. OUTLOOK FOR 1997 In 1997, available seat miles are expected to increase approximately 3.5%, with total system revenue per available seat mile up approximately 3%. Costs per available seat mile excluding ESOP charges are expected to increase approximately 2%. This unit cost forecast assumes the average cost of jet fuel per gallon is lower in 1997 than in 1996. For the second quarter, United expects total system revenue per available seat mile to increase approximately 3% versus the same period last year, on 3% higher capacity. System load factor is forecast to increase slightly compared to second quarter 1996. Costs per available seat mile excluding ESOP charges are expected to increase 3% over the same period last year. Based on the favorable industry environment, advance bookings and first quarter results, the Company anticipates its "fully distributed" earnings per share in 1997 will exceed those for 1996 (see "Results of Operations, Summary of Results" for further explanation of this pro forma methodology). Due to the reinstatement of the Federal passenger excise tax (see below), the Company believes the rate of improvement in year-over-year "fully distributed" earnings for the second and third quarter will be less than in the first quarter. Based on the current favorable industry environment, the Company expects second quarter 1997 "fully distributed" earnings per share to be slightly higher than second quarter 1996. The Federal passenger excise tax, which expired on December 31, 1996, was reinstated during the first quarter. While the authority to collect this tax is scheduled to expire once again at the end of the third quarter, the Company expects a replacement funding mechanism, either reinstatement of the current tax or a substitute user-based fee system, to go into effect at the end of this period. The information included in the previous paragraphs is forward-looking and involves risks and uncertainties that could result in actual results differing materially from expected results. It is not reasonably possible to itemize all of the many factors and specific events that could affect the outlook of an airline operating in the global economy. Some factors that could significantly impact expected capacity, load factors, revenues, unit revenues, unit costs and earnings per share include the airline pricing environment, fuel costs, low-fare carrier expansion, cost of safety and security measures, actions of the U.S., foreign and local governments, foreign currency exchange rate fluctuations, the economic environment of the airline industry, the general economic environment, and other factors discussed herein.

1.     Formula.
       -------

         For those Aircraft scheduled for delivery after
[*CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
CONFIDENTIAL TREATMENT] the Airframe Price Adjustment will be
determined at the time of Aircraft delivery in accordance with
the following formula:

         Pa = (P) (L + M - 1)

         Where:

         Pa = Airframe Price Adjustment.

         L = .65 x ECI
                   ---
                   130.1

         M = .35 x ICI
                   ---
                   123.6

         P = Aircraft Basic Price (as set forth in Article 3.1.3
             of this Agreement) less the base price of Engines (as
             defined in this Exhibit D-1) in the amount of
             [*CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH
             THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A
             REQUEST FOR CONFIDENTIAL TREATMENT]

       ECI = A value using the "Employment Cost Index for workers
             in aerospace manufacturing" (aircraft manufacturing,
             standard industrial classification code 3721,
             compensation, base month and year June 1989 = 100), as
             released by the Bureau of Labor Statistics, U.S.
             Department of Labor on a quarterly basis for the months of
             March, June, September and December, calculated as
             follows:  A three-month arithmetic average value
             (expressed as a decimal and rounded to the nearest tenth)
             will be determined using the months set forth in the table
             below for the applicable Aircraft, with the released
             Employment Cost Index value described above for the month
             of March also being used for the months of January and
             February; the value for June

             also used for April and May; the value for
             September also used for July and August; and the value for
             December also used for October and November.

       ICI = The three-month arithmetic average of the released
             monthly values for the Industrial Commodities Index as set
             forth in the "Producer Prices and Price Index" (Base Year
             1982 = 100) as released by the Bureau of Labor Statistics,
             U.S. Department of Labor values (expressed as a decimal
             and rounded to the nearest tenth) for the months set forth
             in the table below for the applicable Aircraft.

          In determining the value of L, the ratio of ECI divided
by 130.1 will be expressed as a decimal rounded to the nearest
ten-thousandth and then multiplied by .65 with the resulting
value also expressed as a decimal and rounded to the nearest ten-
thousandth.

          In determining the value of M, the ratio of ICI divided
by 123.6 will be expressed as a decimal rounded to the nearest
ten-thousandth and then multiplied by .35 with the resulting
value also expressed as a decimal and rounded to the nearest ten-
thousandth.

2.     If at the time of delivery of an Aircraft Boeing is unable
to determine the Airframe Price Adjustment because the applicable
values to be used to determine the ECI and ICI have not been
released by the Bureau of Labor Statistics, then:

       2.1     The Airframe Price Adjustment, to be used at the
time of delivery of each of the Aircraft scheduled for delivery
after December 31, 1998, will be determined by utilizing the
escalation provisions set forth above.  The values released by
the Bureau of Labor Statistics and available to Boeing 30 days
prior to scheduled Aircraft delivery will be used to determine
the ECI and ICI values for the applicable months (including those
noted as preliminary by the Bureau of Labor Statistics) to
calculate the Airframe Price Adjustment.  If no values have been
released for an applicable month, the provisions set forth in
Paragraph 2.2 below will apply.  If prior to delivery of an
Aircraft the U.S. Department of Labor changes the base year for
determination of the ECI or ICI values as defined above, such
rebased values will be incorporated in the Airframe Price
Adjustment calculation.  The payment by Buyer to Boeing of the
amount of the Purchase Price for such Aircraft, as determined at
the time of Aircraft delivery, will be deemed to be the payment
for such Aircraft required at the delivery thereof.

       2.2     If prior to delivery of an Aircraft the U.S.
Department of Labor substantially revises the methodology used
for the determination of the values to be used to determine the
ECI and ICI values (in contrast to benchmark adjustments or other
corrections of previously released values), or for any reason has
not released values needed to determine the applicable Aircraft
Airframe Price Adjustment, the parties will, prior to delivery of
any such Aircraft, select a substitute for such values from data
published by the Bureau of Labor Statistics or other similar data
reported by non-governmental United States organizations, such
substitute to lead in application to the same adjustment result,
insofar as possible, as would have been achieved by continuing
the use of the original values as they may have fluctuated during
the applicable time period.  Appropriate revision of the formula
will be made as required to reflect any substitute values.
However, if within 24 months from delivery of the Aircraft the
Bureau of Labor Statistics should resume releasing values for the
months needed to determine the Airframe Price Adjustment, such
values will be used to determine any increase or decrease in the
Airframe Price Adjustment for the Aircraft from that determined
at the time of delivery of such Aircraft.

       2.3     In the event escalation provisions are made non-
enforceable or otherwise rendered null and void by any agency of
the United States Government, the parties agree,

PA/NEXD-1

Attachment 3 to

to the extent they may lawfully do so, to equitably adjust the
Purchase Price of any affected Aircraft to reflect an allowance
for increases or decreases in labor compensation and material
costs occurring since February, 1995, which is consistent with
the applicable provisions of paragraph 1 of this Exhibit D.

3.     For the calculations herein, the values released by the
Bureau of Labor Statistics and available to Boeing 30 days prior
to scheduled Aircraft delivery will be used to determine the ECI
and ICI values for the applicable months (including those noted
as preliminary by the Bureau of Labor Statistics) to calculate
the Airframe Price Adjustment.

Note:  Any rounding of a number, as required under this
       Exhibit D-1 with respect to escalation of the airframe
       price, will be accomplished as follows: if the first digit
       of the portion to be dropped from the number to be rounded
       is five or greater, the preceding digit will be raised to
       the next higher number.

herein) will be determined at the time of Aircraft delivery in
accordance with the following formula:

       Pa  =  (P)  (AA  +  BB  +  CC)  -  P

(b)    The following definitions will apply herein:

       Pa  =  Engine Price Adjustment


       P   =  Aggregate Engine Base Price as set forth in
              paragraph (a) above.

       AA  = .60  x  L
                    ---         
                    $17.80

       BB  = .30  x  M
                    ---
                    130.6

       CC  = .10  x  E
                    ---         
                    76.6

In determining the value of AA, BB and CC, the ratio of L divided
by  $17.80,  M  divided by 130.6 and E divided by  76.6  will  be
expressed  as a decimal and rounded to the nearest ten-thousandth
but  the decimal value resulting from multiplying such ratios  by
the  respective constants (.60, .30 and .10) will not be rounded.
The  value of the sum of AA + BB + CC will also be rounded to the
nearest ten-thousandth.

       L   =  Labor  Index, which is the "Hourly Earnings  of
              Aircraft  Engines and Engine Parts Production Workers, SIC
              3724"  published  by the Bureau of Labor  Statistics,  U.S.

              for the seventh month preceding the month of
              scheduled Aircraft delivery.

   $17.80  =  Published Labor Index (SIC 3724) for December, 1994.

        M  =  Material Index, which is the "Producer Price Index
              - Code 10, Metals and Metal Products," (Base Year 1982 =
              100) published by the Bureau of Labor Statistics, U.S.
              Department of Labor, for the seventh month preceding the
              month of scheduled Aircraft delivery.

    130.6  =  Published Material Index (Code 10) for December, 1994.

        E  =  Fuel Index, which is the "Producer Price Index -
              Code 5, Fuels and Related Products and Power" (Base Year
              1982 = 100) published for the Bureau of Labor Statistics,
              U.S. Department of Labor, for the seventh month preceding
              the month of scheduled Aircraft delivery.

     76.6  =  Published Fuel Index (Code 5) for December, 1994.

The Engine Price Adjustment will not be made if it would result
in a decrease in the aggregate Engine base price.

(c)     The value of the Labor, Material and Fuel Index used in
determining the Engine Price Adjustment will be those published
by the Bureau of Labor Statistics, U.S. Department of Labor as of
a date 30 days prior to the scheduled Aircraft delivery to Buyer.
Such Index values will be considered final and no revision to the
Engine Price Adjustment will be made after Aircraft delivery for
any subsequent changes in published Index values.

(d)     If the Bureau of Labor Statistics, U. S. Department of
Labor, (i) substantially revises the methodology (in contrast to
benchmark adjustments or other corrections of previously
published data), or (ii) discontinues publication of any of the
data referred to above or (iii) temporarily discontinues
publication of any of the data referred to above, Pratt & Whitney
Aircraft (P&WA) agrees to meet jointly with Boeing and Buyer and
jointly select a substitute for the revised or discontinued data, such

substitute data to lead in application to the same adjustment
result, insofar as possible, as would have been achieved by
continuing the use of the original data as it may have fluctuated
had it not been revised or discontinued.  Appropriate revision of
the Engine Price Adjustment provisions set forth above will be
made to accomplish this result for affected Engines.

In the event the Engine Price Adjustment escalation provisions of
this Agreement are made non-enforceable or otherwise rendered
null and void by any agency of the United States Government, P&WA
agrees to meet jointly with Boeing and Buyer and jointly agree,
to the extent that they may lawfully do so, to adjust equitably
the purchase price of the Engine(s) to reflect an allowance for
increases in labor, material and fuel costs that occurred from
December, 1994 to the seventh month preceding the month of
scheduled delivery of the applicable Aircraft.

NOTES:  Any rounding of a number, as required under this
        Exhibit D-1 with respect to escalation of the Engine
        price, will be accomplished as follows: if the first
        digit of the portion to be dropped from the number to be
        rounded is five or greater, the preceding digit will be
        raised to the next higher number.
