Item 1. Business
The principal objectives of Polaris Aircraft Income Fund IV (PAIF-IV or the Partnership) are to purchase and lease used commercial jet aircraft in order to provide quarterly distributions of cash from operations, to maximize the residual values of aircraft upon sale and to protect Partnership capital through experienced management and diversification. PAIF-IV was organized as a California limited partnership on June 27, 1984 and will terminate no later than December 2020.
PAIF-IV has many competitors in the aircraft leasing market, including airlines, aircraft leasing companies, other limited partnerships, banks and several other types of financial institutions. This market is highly competitive and there is no single competitor who has a significant influence on the industry. In addition to other competitors, the general partner, Polaris Investment Management Corporation (PIMC), and its affiliates, including Polaris Aircraft Leasing Corporation (PALC), Polaris Holding Company (PHC) and GE Capital Corporation (GE Capital), acquire, lease, finance and sell aircraft for their own accounts and for existing aircraft leasing programs sponsored by them. Accordingly, in seeking to re-lease and sell its aircraft, the Partnership may be in competition with the general partner and its affiliates.
A brief description of the aircraft owned by the Partnership is set forth in Item 2, on page 4. The following table describes the material terms of the Partnership's leases to American Trans Air, Inc. (ATA) and Continental Airlines, Inc. (Continental) as of December 31, 1993:
(1) These aircraft were formerly leased to USAir, Inc. (USAir) through December 1992. The lease rate is approximately 45% of the prior lease rate. The lease includes an eleven month rent abatement period, beginning on the delivery dates in February and March 1993. The ATA lease also specifies that the Partnership incur certain maintenance costs not to exceed approximately $817,000 and, in addition, the Partnership may finance certain aircraft hushkits at an estimated cost of approximately $5.0 million, which will be partially recovered with interest through payments from ATA over the lease terms. The Partnership loaned $1,164,800 to ATA in 1993 to finance the purchase by ATA of two spare engines. As part of the lease transaction, ATA transferred unencumbered title to two of its Boeing
727-100 aircraft to the Partnership in April and May 1993. One of the aircraft was sold as discussed in Item 7 and the Partnership is remarketing the second aircraft for sale or lease.
(2) The Continental leases were modified in 1991; the leases for the Boeing 727-200 aircraft were extended for ten months beyond the initial lease expiration date in June 1993 at approximately 55% of the original lease rates. Continental may terminate the leases for these aircraft at the earlier of April 1994 or 60,000 cycles. The leases for the DC-9-30 aircraft were extended for 36 months beyond the initial lease expiration date in June 1993 at approximately 79% of the original lease rates. The Partnership also agreed to pay for certain aircraft maintenance, modification and refurbishment costs, expected not to exceed approximately $4.9 million, a portion of which will be recovered with interest through payments from Continental over the extended lease terms.
(3) The rental rate during the renewal term remains the same as the current rate.
The Partnership also owns one Boeing 737-200 and one Boeing 737-200 Advanced aircraft formerly leased to Britannia Airways Limited (Britannia), one Boeing 737-200 and three Boeing 737-200 Advanced aircraft formerly leased to Thomson Overseas Finance N.V. (T.O.F.) and subleased to Britannia, and two Boeing 727- 100 aircraft transferred from ATA as part of the ATA lease transaction (Item 7). The four Boeing 737-200 Advanced aircraft were re-leased to various lessees in February 1994 and one of the Boeing 727-100 aircraft was sold in February 1994 as discussed in Item 7. In addition, fourteen Boeing 727-100F aircraft were sold to Emery Aircraft Leasing Corporation (Emery) in 1993 (Item 7).
Approximately 700 commercial aircraft are currently available for sale or lease. The current surplus has negatively affected market lease rates and fair market values of both new and used aircraft. Current depressed demand for air travel has limited airline expansion plans, with new aircraft orders and scheduled delivery being cancelled or substantially deferred. As profitability has declined, many airlines have opted to downsize, liquidate assets or file for bankruptcy protection. The Partnership has been forced to adjust its estimates of the residual values realizable from its aircraft and aircraft inventory, which resulted in an increase in depreciation expense in 1993, 1992 and 1991, as discussed in Note 3 to the financial statements of the Form 10-K (Item 8). A discussion of the current market condition for the type of aircraft owned by the Partnership follows:
Boeing 727-100 The Boeing 727 was the first tri-jet introduced into commercial service. The Boeing 727-100 is a short to medium range jet carrying approximately 125 passengers on trips of up to 1,500 miles. The operating characteristics of the aircraft, as well as the cost of aging aircraft and corrosion control Airworthiness Directives (ADs), have significantly reduced the possibility of re-leasing this type of aircraft.
Boeing 727-100 Freighter The Boeing 727 was the first tri-jet introduced into commercial service. The Boeing 727-100F is a short to medium range jet which has been converted to carry freight on trips of up to 1,500 miles. The high
cost of complying with Aging Aircraft and Corrosion ADs have contributed to a general decline in the market demand for this aircraft. Additionally, the demand for Boeing 727-100 Freighter aircraft is diminishing as major freight operators look to larger, more efficient aircraft to meet future requirements.
Boeing 727-200 and Boeing 727-200 Advanced The Boeing 727 was the first tri-jet introduced into commercial service. The Boeing 727 is a short to medium range jet used for trips of up to 1,500 miles. The Boeing 727-200 aircraft was introduced in 1967 and 299 were built between 1967 and 1972. In 1972, Boeing introduced the Boeing 727-200 Advanced model, a higher gross weight version with increased fuel capacity. Noise suppression hardware, commonly known as a "hushkit," has been developed which, when installed on the aircraft, bring the Boeing 727-200 and the Boeing 727-200 Advanced into compliance with Federal Aviation Administration (FAA) Stage 3 noise limits as discussed in the Industry Update section of Item 7. The cost of the hushkit is approximately $1.75 million for the Boeing 727-200 aircraft and approximately $2.5 million for the Boeing 727-200 Advanced aircraft. However, while technically feasible, hushkits may not be cost effective on all aircraft due to the age of some of the aircraft and the time required to fully amortize the additional investment. Certain ADs applicable to all models of the Boeing 727 have been issued to prevent fatigue cracks and control corrosion. Demand for Boeing 727-200 aircraft is currently very soft due to the general oversupply of narrowbody aircraft.
Boeing 737-200 and Boeing 737-200 Advanced The Boeing 737-200 aircraft was introduced in 1967 and 950 were delivered from 1967 through 1971. In 1971, Boeing introduced the Boeing 737-200 Advanced model, a higher gross weight aircraft with increased fuel capacity as compared to its predecessor, the non-advanced model. This two engine, two pilot aircraft provides operators with 107 to 120 seats, meeting their requirements for economical lift in the 1,100 nautical mile range. A domestic company is selling hushkits which bring Boeing 737s into compliance with Stage 3 noise restrictions at a cost of approximately $3.0 million per aircraft. The market for this type of aircraft, as for all Stage 2 narrowbody aircraft, is currently soft.
McDonnell Douglas DC-9-30 The McDonnell Douglas DC-9-10, a short to medium range twin-engine jet, was introduced in 1965. The DC-9-30, which is a stretched version of the DC-9-10, was introduced in 1967. This model offered improved performance when carrying heavier loads. Over 970 DC-9 aircraft were produced and there are approximately 56 operators worldwide. Providing reliable, inexpensive lift, these aircraft fill thin niche markets, mostly in the United States. Hushkits at a cost of approximately $1.6 million are available to bring these aircraft into compliance with Stage 3 requirements. The market for this type of aircraft is currently soft.
It is expected that the FAA will continue to propose and adopt ADs similar to those discussed above for the Boeing 737s and Boeing 727s, which will require modifications at some point in the future to prevent fatigue cracks and control corrosion. Likewise demand, and hence value, of the aircraft may be diminished to the extent that the costs of bringing DC-9 aircraft into compliance with any ADs reduces the economic efficiency of operating these aircraft.
The general partner believes that the current soft market reflects, in addition to the factors cited above, the airline industry's reaction to the significant expenditures potentially necessary to bring these aircraft into compliance with certain ADs issued by the FAA relating to aging aircraft, corrosion prevention and control and structural inspection and modification.

Item 6.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
Polaris Aircraft Income Fund IV (the Partnership) owns 19 commercial jet aircraft. The portfolio includes five DC-9-30 and five Boeing 727-200 aircraft leased to Continental Airlines, Inc. (Continental), two Boeing 727-200 Advanced aircraft leased to American Trans Air, Inc. (ATA), two Boeing 737-200 Advanced aircraft formerly leased or subleased to Britannia Airways Limited (Britannia) which were leased to GB Airways Limited (GB Airways) in February 1994, and two Boeing 737-200 Advanced aircraft formerly leased or subleased to Britannia, which were leased to TBG Airways Limited (TBG Airways) in February 1994. ATA transferred to the Partnership two Boeing 727-100 aircraft in 1993 as part of the ATA lease transaction. One of these Boeing 727-100 aircraft was sold to Total Aerospace Services, Inc. (Total Aerospace) in February 1994 and one is being remarketed for sale or lease. Also being remarketed for sale or lease are two Boeing 737-200 aircraft formerly leased or subleased to Britannia. Out of an original portfolio of 33 aircraft, one Boeing 727-100 Freighter formerly leased to Emery Aircraft Leasing Corporation (Emery) was declared a casualty loss due to an accident in 1991 and fourteen Boeing 727-100 Freighters were sold to Emery in 1993 as described below.
Partnership Operations
The Partnership recorded net income of $4,226,843, $13,817,873 and $6,168,184, for the years ended December 31, 1993, 1992 and 1991, respectively. Net income per limited partnership unit was $4.62, $22.86 and $6.66, in 1993, 1992 and 1991, respectively. The sharp decrease in net income for 1993 from 1992 is primarily attributable to declines in rental revenue. The Emery aircraft were sold at the termination of the extended leases in January and April 1993, and no further rentals were received, compared to a full year of rental payments in 1992. The Britannia lease extension in June 1993 through October, November and December 1993 were at rates ranging from 53% to 85% of the original rates. In addition, the ATA lease rates are 45% of the previous USAir, Inc. (USAir) rates earned in 1992. Partially offsetting these declines are a full year of interest and rental income recognized on the first Continental rent deferral and three months recognized on the additional deferral. Revenues during 1993 included an aggregate net loss of $492,319 recognized on the sale of aircraft to Emery.
Further impacting the lower net income for 1993 were aircraft operating expenses, including maintenance and remarketing costs, necessary to re-lease the 727-200 Advanced aircraft from USAir to ATA.
Depreciation expense was increased to reflect industry-wide declines in demand, as discussed in the industry update section. Depreciation adjustments for 1993 were approximately $0.6 million in 1993 compared to adjustments of $0.1 million and $3.6 million for 1992 and 1991, respectively.
Cash Distributions and Liquidity
Cash Distributions Distributions of cash available from operations commenced in the fourth quarter of 1987. Cash distributions from operations to limited partners totalled $18,748,650, $22,498,380 and $27,778,000, or $37.50, $45.00 and $55.56 per limited partnership unit in 1993, 1992 and 1991, respectively. In July 1993, a cash distribution of the sale proceeds from the Emery sale was made totalling $22,498,380, or $45.00 per limited partnership unit. The amount of future cash distributions will depend on the Partnership's future cash requirements, the successful re-lease of the off-lease aircraft and receipt of rental payments from Continental, ATA, GB Airways and TBG Airways. A portion of the Partnership's cash reserves will be applied toward costs specified below.
Liquidity The Partnership has received all rental payments due from its lessees. The agreement with Continental stipulates that the Partnership pay for the costs of certain maintenance work, Airworthiness Directives compliance, aircraft modification and refurbishment costs, which are not to exceed approximately $4.9 million, and which will partially be recovered with interest through payments from Continental over the extended lease terms. In 1993, no rental payments were received during the ATA rent suspension period. The ATA lease also specifies that the Partnership incur certain maintenance costs not to exceed approximately $817,000 and, in addition, the Partnership may finance certain aircraft hushkits at an aggregate cost of approximately $5.0 million, a portion of which will be partially recovered with interest through payments from ATA over the lease terms. The Partnership will use a portion of its cash reserves of approximately $16.4 million as of December 31, 1993 to finance these costs. The remainder of the reserves will be retained to cover potential costs of remarketing the Partnership's aircraft, including remarketing or sale of the five Boeing 727-200 aircraft coming off-lease from Continental in April 1994.
Remarketing Update
Sale of aircraft to Emery One of the aircraft leased to Emery was sold to Emery at the end of its lease term in January 1993 for $1.5 million, in accordance with the purchase option in the lease. The Partnership recorded a loss on sale of $555,676. Subsequently, Emery exercised its option to purchase the remaining 13 Boeing 727-100 Freighter aircraft for $2.0 million each at the end of April 1993. The Partnership reported an aggregate gain of $63,357 on these sales. Proceeds from the sale were distributed to the partners in July 1993 as previously discussed.
Lease to ATA - In December 1992, the Partnership negotiated a seven-year lease with ATA for the ex-USAir aircraft at current fair market lease rates, which are approximately 45% of the prior rates. The leases are renewable for up to three one-year periods. The Partnership has permitted a rent suspension period of approximately eleven months, beginning on the delivery dates in February and March 1993. The Partnership also agreed to incur certain maintenance costs and may provide financing for hushkits and spare engines for use on the aircraft.
ATA transferred unencumbered title to two of its Boeing 727-100 aircraft to the Partnership as part of the lease transaction in 1993. One of the aircraft was sold as discussed below and the Partnership is remarketing the second aircraft for sale or lease.
The Partnership loaned $1,164,800 to ATA in 1993 to finance the purchase by ATA of two spare engines. This loan is reflected in notes receivable in the accompanying balance sheet of the Partnership's 1993 Form 10-K (Item 8). During 1993, the Partnership received all scheduled principal and interest payments due under the notes totalling $87,139. The balance of the note at December 31, 1993 was $1,103,089.
Sale to Total Aerospace - In February 1994, the Partnership sold one of the Boeing 727-100 aircraft that was transferred to the Partnership by ATA, as discussed above, to Total Aerospace for $425,000. The Partnership will record a gain on sale of $425,000 in 1994.
Lease to GB Airways - In February 1994, the Partnership leased two Boeing 737- 200 Advanced aircraft that were formerly on lease to Britannia to GB Airways. Lease payments for an interim lease term through March 1994 are at a variable rate based on usage. Thereafter and through March 1996, the lease rate is 58% of the original rate received from Britannia. The rate is then adjusted through the end of the lease in October 1996 to 67% of the original rate received from Britannia. GB Airways has the option to extend the lease for one year at the initial rate. The lease stipulates that the Partnership share in the cost of certain modification and refurbishment costs which are inestimable at this time.
Lease to TBG Airways - In February 1994, the Partnership leased the remaining two Boeing 737-200 Advanced aircraft that were formerly on lease to Britannia to TBG Airways. Lease payments for an interim lease term through April 1994 are at a variable rate based on usage. Thereafter and through the end of the lease in October 1998, the rate is increased annually from 55% to as much as 80% of the original rate received from Britannia. The lease stipulates that the Partnership share in the cost of certain modification and refurbishment costs which are inestimable at this time. TBG Airways has the option to early terminate the lease in April 1997 after paying a termination fee of $250,000. TBG Airways also has the option to purchase the aircraft at the end of the lease term for $8.0 million each.
Aircraft Casualty Incident
In May 1991, one of the Partnership's Boeing 727-100 Freighter aircraft leased to Emery was damaged as a result of fire while it was on the ground. Emery paid to the Partnership the casualty value specified in the lease of $4,310,000, which was equal to the Partnership's cost for the aircraft, resulting in a gain of $1,391,503. A portion of the proceeds from the casualty occurrence were distributed to unit holders in July 1991. The distribution of $3,874,721, or $7.75 per limited partnership unit, represented a distribution from casualty proceeds, as opposed to a distribution of cash from operations.
Continental Lease Modification
As discussed in the Partnership's Form 10-K for the year ended December 31, 1990, Continental filed for Chapter 11 bankruptcy protection in December 1990. Continental emerged from bankruptcy protection under a reorganization plan approved by the Bankruptcy Court effective April 28, 1993. The modified agreement approved by the Bankruptcy Court in 1991 specifies (i) extension of the leases for the five Boeing 727-200s to the earlier of April 1994 or 60,000 cycles, and for the five DC-9-30 aircraft to June 1996; (ii) renegotiated rental rates averaging approximately 67% of the original lease rates; (iii) payment of ongoing rentals at the reduced rates beginning in October 1991; (iv) payment of deferred rentals with interest beginning in July 1992; and (v) payment by the
Partnership of certain aircraft modification and refurbishment costs, not to exceed approximately $4.9 million, a portion of which will be recovered with interest through payments from Continental over the extended lease term. The Partnership's balance sheets reflect the net reimbursable costs incurred of $419,212 and $206,777 as of December 31, 1993 and 1992, respectively, as notes receivable in the balance sheet of the Partnership's 1993 Form 10-K (Item 8). A portion of these will be capitalized and depreciated over the remaining lease term. Under certain circumstances related to a possible future substantial downsizing, Continental will be entitled to reject the existing leases. These circumstances are not currently expected to materialize.
The Partnership recognized rent receivable from Continental of $960,152 in its financial statements for the year ended December 31, 1990. As a result of the terms of the agreement, which included an extended deferral of the dates when Continental will remit its rental payments for the period from December 3, 1990 through September 30, 1991 (the Deferred Amount), the Partnership has not recognized the Deferred Amount as rental revenue until it is received, or until the contingencies regarding collectability are removed. Accordingly, the rent receivable recognized at December 31, 1990 was reversed in the first quarter of 1991. The unrecognized Deferred Amounts as of December 31, 1993 and 1992 were $3,281,033 and $5,476,604, respectively. In accordance with the aforementioned agreement, Continental began making supplemental payments for accrued unpaid rent plus interest on July 1, 1992. During 1993 and 1992, the Partnership received supplemental payments of $3,186,649 and $1,593,324, respectively, of which $2,195,572 and $973,395 was recognized as rental income in 1993 and 1992, respectively.
Additional Continental Deferral Agreement As part of its reorganization plan, Continental requested additional concessions from its aircraft lessors. As a result, the Partnership and Continental reached an agreement to defer rental payments for a period of three months, beginning in November 1992, for a total of $1,935,000 (Additional Deferred Amount), with repayment over the shorter of three and one-half years or the remaining lease term. Repayment began October 1, 1993. The unrecognized Additional Deferred Amount as of December 31, 1993 was $1,810,282. Continental continues to pay all other amounts due under the prior agreement. During 1993, the Partnership received supplemental payments of $170,070, of which $124,718 was recognized as rental income in 1993.
The Partnership's right to receive payments under the agreements fall into various categories of priority under the Bankruptcy Code. In general, the Partnership's claims are administrative claims, with the exception of certain deferred amounts. If Continental's reorganization is not successful, it is likely that a portion of the Partnership's claims will not be paid in full.
Refund of Hushkit Deposits
In 1990, the Partnership agreed to acquire up to 12 hushkits for Boeing 727 aircraft from Federal Express Corporation (Federal Express). Because certain conditions to the purchase of the hushkits were not satisfied, the Partnership requested return of its deposit of $330,000 plus interest as provided in the purchase documents. Federal Express refused the Partnership's request, pending
resolution with the Partnership of certain allegedly disputed contractual issues. In April 1992, the general partner, on behalf of the Partnership, commenced legal action to require Federal Express to refund the remaining balance of the deposit, with interest, plus legal fees and other damages, and Federal Express filed a cross-complaint against the Partnership alleging breach of contract. A settlement was reached and payment of the deposit, with interest, was received by the Partnership in November 1992.
Reconciliation of Book Income to Taxable Income
The following is a reconciliation between net income per limited partnership unit reflected in the financial statements of Form 10-K (Item 8) and information provided to unit holders for federal income tax purposes:
The differences between net income for book purposes and net income for tax purposes result from the timing differences of certain income and deductions. The Partnership computes depreciation using the straight line method for financial reporting and tax purposes; however, the aircraft are depreciated using a shorter life for tax purposes. Thus, the current year tax depreciation expense is greater than book depreciation expense and provides unit holders with the benefit of deferring taxation on a portion of their cash distributions. The Partnership also periodically evaluates the ultimate recoverability of the carrying values and the economic lives of its aircraft for book purposes and, accordingly, recognized adjustments which increased depreciation expense by approximately $0.6 million, or $1.19 per limited partnership unit, during 1993. The depreciation differences resulted in a larger tax gain on sale of aircraft then the book gain. Finally, certain costs were capitalized for tax purposes and expensed for book purposes.
In addition, there are differences between the recognition of certain deferred rental income for book and tax purposes. As previously discussed, one of the Partnership's lessees, Continental, filed for Chapter 11 bankruptcy protection. The Partnership and Continental subsequently reached agreement as to the payment of deferred and future rentals. The original deferred rentals were converted into promissory notes bearing interest at a 12% rate, to be repaid by Continental over periods of up to 48 months beginning in July 1992. The subsequent deferred rentals will likely be converted to notes under a similar
agreement. For book purposes, the Partnership will not recognize any of these deferred rentals, or the related interest, as income, nor will it accrue management fee expense on such rentals, until the amounts due are received from Continental. However, for tax purposes, these amounts have been accrued over the period in which they were earned. In addition, the Partnership received title to two aircraft from its' lessee ATA. For tax purposes, the fair market value of these aircraft was recorded as rental income. For book purposes, rental income was accrued for the ATA rent suspension period. These recognition differences resulted in a book net rental income in excess of tax.
Industry Update
Maintenance of Aging Aircraft The process of aircraft maintenance begins at the aircraft design stage. For aircraft operating under Federal Aviation Administration (FAA) regulations, a review board consisting of representatives of the manufacturer, FAA representatives and operating airline representatives is responsible for specifying the aircraft's initial maintenance program. This program is constantly reviewed and modified throughout the aircraft's operational life.
Since 1988, the FAA, working with the aircraft manufacturers and operators, has issued a series of Airworthiness Directives (ADs) which mandate that operators conduct more intensive inspections, primarily of the aircraft fuselages. The results of these mandatory inspections may uncover the need for repairs or structural modifications that may not have been required under existing maintenance programs.
In addition, an AD adopted in 1990 requires replacement or modification of certain structural items on a specific timetable. These structural items were formerly subject to periodic inspection, with replacement when necessary. The FAA estimates the cost of compliance with this AD to be approximately $1.0 million and $0.9 million per Boeing 727 and Boeing 737 aircraft, respectively, if none of the required work had been done previously. The FAA also issued several ADs in 1993 updating inspection and modification requirements for Boeing 737 aircraft. The FAA estimates the cost of these requirements to be approximately $90,000 per aircraft. In general, the new maintenance requirements must be completed by the later of March 1994, or 75,000 and 60,000 cycles for each Boeing 737 and 727 respectively. A similar AD was adopted on September 24, 1990, applicable to McDonnell Douglas aircraft. The AD requires specific work to be performed at various cycle thresholds between 50,000 and 100,000 cycles, and on specific date or age thresholds. The estimated cost of compliance with all of the components of this AD is $1.0 million per aircraft.
In December 1990, the FAA adopted another AD intended to mitigate corrosion of structural components, which would require repeated inspections from 5 years of age throughout the life of an aircraft, with replacement of corroded components as needed. Integration of the new inspections into each aircraft operator's maintenance program was required by December 31, 1991 on Boeing aircraft. A similar directive was issued in late 1992 for McDonnell Douglas aircraft.
The Partnership's existing leases require the lessees to maintain the Partnership's aircraft in accordance with an FAA-approved maintenance program during the lease term. At the end of the leases, each lessee is generally required to return the aircraft in airworthy condition including compliance with all ADs for which action is mandated by the FAA during the lease term, except for certain instances. In negotiating subsequent leases, market conditions generally require that the Partnership bear some or all of the costs of compliance with future ADs or ADs that have been issued, but which did not require action during the previous lease term. The ultimate effect on the Partnership of compliance with the FAA maintenance standards is not determinable at this time and will depend on a variety of factors, including the state of the
commercial aircraft market, the timing of the issuance of ADs, and the status of compliance therewith at the expiration of the current leases.
Aircraft Noise Another issue which has affected the airline industry is that of aircraft noise levels. The FAA has categorized aircraft according to their noise levels. Stage 1 aircraft, which have the highest noise level, are, with few exceptions, no longer allowed to operate from civil airports in the United States. Stage 2 aircraft meet current FAA requirements. Stage 3 aircraft are the most quiet and Stage 3 is the standard for all new aircraft.
On September 24, 1991, the FAA issued final rules on the phase-out of Stage 2 aircraft by the end of this decade. The current U.S. fleet is comprised of approximately 51% Stage 3 aircraft and 49% Stage 2 aircraft. The key features of the rule include:
Compliance can be accomplished through a gradual process of phase-in or phase-out (see below) on each of three interim compliance dates: December 31, 1994, 1996 and 1998 (with waivers available in certain specific cases to December 31, 2003).
All operators have the option of achieving compliance through a gradual phase-out of Stage 2 aircraft (i.e., eliminate 25% of its Stage 2 fleet on each of the compliance dates noted above), or a gradual phase-in of Stage 3 aircraft (i.e., 55%, 65% and 75% of an operator's fleet must consist of Stage 3 aircraft by the respective compliance dates noted above).
Carryforward credits will be awarded to operators for early additions of Stage 3 aircraft to their fleets. These credits may be used to reduce either the number of Stage 2 aircraft it must phase-out or the number of Stage 3 aircraft it must phase-in by the next interim compliance date. The credits must be used by that operator, however, and cannot be transferred or sold to another operator.
The federal rule does not prohibit local airports from issuing more stringent phase-out rules. In fact, several local airports have adopted more stringent noise requirements which restrict the operation of Stage 2 and certain Stage 3 aircraft.
Other countries have also adopted noise policies. The European Economic Community (EEC) adopted a non-addition rule in 1989, which directed each member country to pass the necessary legislation to prohibit airlines from adding Stage 2 aircraft to their fleets after November 1, 1990. The rule has specific exceptions for leased aircraft and does allow the continued use of Stage 2 aircraft which were in operation before November 1, 1990, although adoption of rules requiring the eventual phase-out of Stage 2 aircraft is anticipated.
The Partnership's entire fleet consists of Stage 2 aircraft. Hushkit modifications, which allow Stage 2 aircraft to meet Stage 3 requirements, are currently available for the Partnership's aircraft. However, while technically feasible, hushkits may not be cost effective on all models due to the age of some of the aircraft and the time required to fully amortize the additional investment. The general partner will evaluate, as appropriate, the potential
benefits of hushkitting some or all of the Partnership's aircraft. It is unlikely, however, that the Partnership will incur such costs unless they can be recovered through a lease.
Implementation of the Stage 3 standards have adversely affected the value of Stage 2 aircraft, as these aircraft will require eventual modification to be operated in the U.S. or other countries with Stage 3 standards.
Demand for Aircraft Approximately 700 commercial aircraft are currently available for sale or lease. The current surplus has negatively affected market lease rates and fair market values of both new and used aircraft. Current depressed demand for air travel has limited airline expansion plans, with new aircraft orders and scheduled delivery being cancelled or substantially deferred. As profitability has declined, many airlines have opted to downsize, liquidate assets, or file for bankruptcy protection.
Effects on the Partnership's Aircraft The Partnership has made downward adjustments to its estimates of aircraft value for certain of its on-lease aircraft. To ensure that the carrying value of each asset equals its estimated residual value at the end of its expected holding period, where appropriate the Partnership has increased depreciation expense. The Partnership also made downward adjustments to the carrying values of certain of its off-lease aircraft where depreciated cost exceeded the estimated net realizable value. During 1993, 1992 and 1991, the Partnership recognized downward adjustments totalling $0.6 million, $0.1 million and $3.6 million, respectively, for certain of its aircraft. These adjustments are included in depreciation expense in the statements of income.
The Partnership's leases expire between April 1994 and March 2000. Current market studies indicate that the Partnership's non-advanced Boeing and McDonnell Douglas aircraft continue to be adversely affected by industry events. Therefore, the Partnership will evaluate each aircraft as it comes off lease to determine whether a re-lease or a sale at the then current market rates would be most beneficial for unit holders.
Other Event
Effective October 18, 1993, James F. Walsh resigned as Senior Vice President and Chief Financial Officer of Polaris Investment Management Corporation to assume new responsibilities at GE Capital Corporation. Bobbe V. Sabella has assumed the position of Vice President and Chief Financial Officer. Ms. Sabella has served the general partner in various capacities since September 1986, most recently as Vice President-Finance of Polaris Investment Management Corporation.

POLARIS AIRCRAFT INCOME FUND IV (A California Limited Partnership)
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 1993
1. Accounting Principles and Policies
Accounting Method Polaris Aircraft Income Fund IV (PAIF-IV or the Partnership), a California Limited Partnership, maintains its accounting records, prepares financial statements and files its tax returns on the accrual basis of accounting.
Aircraft and Depreciation The aircraft are recorded at cost, which includes acquisition costs. Depreciation to an estimated residual value is computed using the straight-line method over the estimated economic life of the aircraft which was originally estimated to be 30 years from the date of manufacture. Depreciation in the year of acquisition is calculated based upon the number of days that the aircraft are in service.
The Partnership periodically reviews the estimated realizability of the residual values at the end of each aircraft's economic life. For any downward adjustment in estimated residual, or change in the estimated remaining economic life, the depreciation expense over the remaining life of the aircraft is increased. If the expected net income generated from the lease (rental revenue, net of management fees, less adjusted depreciation and an allocation of estimated administrative expense) results in a net loss, that loss will be recognized currently. Off-lease aircraft are carried at the lower of depreciated cost or estimated net realizable value. A further adjustment is made for those aircraft, if any, that require substantial maintenance work.
Capitalized Costs Aircraft modification and maintenance costs which are determined to increase the value or extend the useful life of the aircraft are capitalized and amortized using the straight-line method over the appropriate period. These costs are also subject to the periodic evaluation discussed above.
Operating Leases The aircraft leases are accounted for as operating leases. Lease revenues are recognized in equal installments over the terms of the leases.
Other Assets Lease acquisition costs are capitalized as other assets and amortized using the straight-line method over the term of the lease.
Income Taxes The Partnership files federal and state information income tax returns only. Taxable income or loss is reportable by the individual partners.
Net Income Per Limited Partnership Unit Net income per limited partnership unit is based on the limited partners' share of net income and the number of units outstanding for the years ended December 31, 1993, 1992, and 1991.
Short-Term Investments The Partnership classifies all liquid investments with original maturities of three months or less as short-term investments.
2. Organization
The Partnership was formed on June 27, 1984 for the purpose of acquiring and leasing aircraft. The Partnership will terminate no later than December 2020. Upon organization, both the general partner and the depositary contributed $500. The Partnership recognized no profits or losses during the periods ended December 31, 1984, 1985 and 1986. The offering of depositary units (Units), representing assignments of limited partnership interest, terminated on September 15, 1988, at which time the Partnership had sold 500,000 units of $500, representing $250,000,000. All unit holders were admitted to the Partnership on or before September 15, 1988. During November 1988, 36 units were returned to the Partnership by an investor who did not meet the Investor Suitability Standards described in the Prospectus. Allocations to affiliates are described in Note 8.
Polaris Investment Management Corporation (PIMC), the sole general partner of the Partnership, supervises the day-to-day operations of the Partnership. PIMC is a wholly-owned subsidiary of Polaris Aircraft Leasing Corporation (PALC). Polaris Holding Company (PHC) is the parent company of PALC. GE Capital Corporation (GE Capital), an affiliate of General Electric Company, owns 100% of PHC's outstanding common stock.
3. Aircraft
The Partnership owns 20 aircraft from its original portfolio of 33 used commercial jet aircraft which were acquire, leased or sold as discussed below.
All aircraft acquired from an affiliate were purchased within one year of the affiliate's acquisition at the affiliate's original price paid. Two aircraft were transferred from a lessee as discussed below. The aircraft leases are generally net leases, requiring the lessees to pay all operating expenses associated with the aircraft during the lease term including Airworthiness Directives (ADs) which have been or may be issued by the Federal Aviation Administration (FAA) and require compliance during the lease term. The leases generally state a minimum acceptable return condition for which the lessee is liable under the terms of the lease agreement.
Two Boeing 727-100 These aircraft were transferred from ATA to the Partnership in April and May 1993 as part of the ATA lease transaction. One of these aircraft was sold in February 1994 as discussed in Note 10. The Partnership is remarketing the second Boeing 727-100 aircraft for sale or lease.
Fifteen Boeing 727-100 Freighter These aircraft were acquired for $64,610,000 in 1988 and leased to Emery Aircraft Leasing Corporation (Emery) until August 1993, except for one aircraft which was retired in May 1991 due to a casualty incident as discussed in Note 4. In January 1993, Emery purchased one of the aircraft for $1.5 million, in accordance with the purchase option in the lease (Note 5). In April 1993, Emery exercised its option to purchase the remaining 13 Boeing 727-100 Freighter aircraft for $2.0 million each (Note 5).
Two Boeing 737-200 and Four 737-200 Advanced These aircraft were acquired for $55,000,000 in 1988 and leased or subleased to Britannia Airways Limited (Britannia) until June 1993. The leases were extended beyond their initial termination dates for approximately four months through the end of September 1993 at lease rates ranging from 53% to 85% of the original rates. The leases were then again extended through various dates in October, November and December 1993, at the modified rates, which coincide with the commencement of maintenance work required of the lessee to meet return conditions specified in the lease. The four Boeing 737-200 Advanced aircraft were re-leased in February 1994 as discussed in Note 10. The remaining two aircraft are being remarketed for sale or lease.
Five Boeing 727-200 and Five McDonnell Douglas DC-9-30 These aircraft were acquired for $64,875,000 in 1988 and leased to Continental Airlines, Inc. (Continental) for terms of 60 months. Continental filed for Chapter 11 bankruptcy protection in December 1990. In 1991, the Partnership and Continental entered into an agreement for Continental's continued lease of the Partnership's aircraft. Note 6 contains a detailed discussion of the Continental lease modifications.
Two Boeing 727-200 Advanced These aircraft were acquired for $27,000,000 in 1988 and leased to USAir, Inc. (USAir) until late 1992. USAir paid rent through December 1992 although the aircraft were returned prior to that time.
In December 1992, the Partnership negotiated a seven year lease with ATA for the aircraft at approximately 45% of the prior rate. The leases began in February and March 1993. ATA is not required to begin making cash rental payments until January 1994, although recognition of rental income will be spread over the entire base lease term. The leases are renewable for up to three one-year periods. ATA transferred to the Partnership two unencumbered Boeing 727-100 aircraft as part of the lease transaction as previously discussed.
The Partnership agreed to incur certain maintenance costs estimated at approximately $817,000. In addition, the Partnership may finance aircraft hushkits for use on the aircraft at an estimated cost of approximately $5.0 million, which will be partially recovered with interest through payment from ATA over the lease terms. The Partnership loaned $1,164,800 to ATA in 1993 to finance the purchase by ATA of two spare engines. This loan is reflected in notes receivable in the accompanying balance sheet. During 1993, the Partnership received all scheduled principal and interest payments due under the notes. The balance of the notes at December 31, 1993 was $1,103,089.
The following is a schedule by year of future minimum rental payments under all of the existing leases, including the deferred rental payments specified in the Continental lease modification (Note 6):
Continental Deferred Rental Year Amount (1) Payments Total 1994 $1,981,818 $ 6,970,062 $ 8,951,880 1995 1,675,095 6,147,144 7,822,239 1996 1,267,713 3,852,144 5,119,857 1997 166,689 1,557,144 1,723,833 1998 and thereafter - 3,341,372 3,341,372
$5,091,315 $ 21,867,866 $ 26,959,181
(1) Rental payments for the period from December 1990 through September 1991 are payable with interest commencing in July 1992 according to the Continental lease modification agreement. Rental payments for the period from November 1992 through January 1993 are payable with interest commencing in October 1993 according to the agreement with Continental. These payments are shown separately because of contingencies regarding collectability as discussed in Note 6.
Future minimum rental payments may be offset or reduced by future costs as discussed in Note 6.
During 1993, 1992 and 1991 the Partnership made downward adjustments to its estimates of aircraft value for certain of its on-lease aircraft. To ensure that the carrying value of each asset equals its estimated residual value at the end of its expected holding period, where appropriate the Partnership has increased depreciation expense as described in Note 1. The Partnership also made downward adjustments to the carrying values of certain of its off-lease aircraft where depreciated cost exceeded the estimated net realizable value. During 1993, 1992 and 1991, the Partnership recognized downward adjustments totalling $0.6 million, $0.1 million and $3.6 million, respectively, for certain of its off-lease and on-lease aircraft. These adjustments are included in depreciation expense in the statements of income.
4. Aircraft Casualty Incident
In May 1991, one of the Partnership's Boeing 727-100 Freighter aircraft leased to Emery was damaged as a result of fire while it was on the ground. Emery paid to the Partnership the casualty value specified in the lease of $4,310,000, which was equal to the Partnership's cost for the aircraft, resulting in a gain of $1,391,503. A portion of the proceeds from the casualty occurrence were distributed to unit holders in July 1991.
5. Sale of Aircraft to Emery One of the aircraft leased to Emery was sold to Emery at the end of its lease term in January 1993 for $1.5 million, in accordance with the purchase option in the lease. The Partnership recorded a loss on sale of $555,676. Subsequently, Emery exercised its option to purchase the remaining 13 Boeing 727-100 Freighter aircraft for $2.0 million each at the end of April 1993. The Partnership reported an aggregate gain of $63,357 on these sales.
6. Continental Lease Modification
As discussed in the Partnership's Form 10-K for the year ended December 31, 1990, Continental filed for Chapter 11 bankruptcy protection in December 1990. Continental emerged from bankruptcy protection under a reorganization plan approved by the Bankruptcy Court effective April 28, 1993. The modified agreement approved by the Bankruptcy Court in 1991 specifies (i) extension of the leases for the five Boeing 727-200s to the earlier of April 1994 or 60,000 cycles, and for the five DC-9-30 aircraft to June 1996; (ii) renegotiated rental rates averaging approximately 67% of the original lease rates; (iii) payment of ongoing rentals at the reduced rates beginning in October 1991; (iv) payment of deferred rentals with interest beginning in July 1992; and (v) payment by the Partnership of certain aircraft modification and refurbishment costs, not to exceed approximately $4.9 million, a portion of which will be recovered with interest through payments from Continental over the extended lease term. The Partnership's balance sheets reflect the net reimbursable costs incurred of $419,212 and $206,777 as of December 31, 1993 and 1992, respectively, as notes receivable. A portion of such costs which the Partnership will bear will be capitalized and depreciated over the remaining lease term. Continental will be entitled, under certain circumstances related to a possible future substantial downsizing by Continental, which is not currently anticipated, to reject the existing leases.
The Partnership recognized rent receivable from Continental of $960,152 in its financial statements for the year ended December 31, 1990. As a result of the terms of the agreement, which included an extended deferral of the dates when Continental will remit its rental payments for the period from December 3, 1990 through September 30, 1991 (the Deferred Amount), the Partnership has not recognized the Deferred Amount as rental revenue until it is received, or until the contingencies regarding collectability are removed. Accordingly, the rent receivable recognized at December 31, 1990 was reversed in the first quarter of 1991. The unrecognized Deferred Amounts as of December 31, 1993 and 1992 were $3,281,033 and $5,476,604, respectively. In accordance with the aforementioned agreement, Continental began making supplemental payments for accrued unpaid rent plus interest on July 1, 1992. During 1993 and 1992, the Partnership received supplemental payments of $3,186,649 and $1,593,324, respectively, of which $2,195,572 and $973,395 was recognized as rental income in 1993 and 1992, respectively.
Additional Continental Deferral Agreement As part of its reorganization plan, Continental requested additional concessions from its aircraft lessors. As a
result, the Partnership and Continental reached an agreement to defer rental payments for a period of three months beginning in November 1992, for a total of $1,935,000 (Additional Deferred Amount), with repayment over the shorter of three and one-half years or the remaining lease term. Repayment began October 1, 1993. The unrecognized Additional Deferred Amount as of December 31, 1993 was $1,810,282. Continental continues to pay all other amounts due under the prior agreement. During 1993, the Partnership received supplemental payments of $170,070, of which $124,717 was recognized as rental income in 1993.
The Partnership's right to receive payments under the agreements fall into various categories of priority under the Bankruptcy Code. In general, the Partnership's claims are administrative claims, with the exception of certain deferred amounts. If Continental's reorganization is not successful, it is likely that a portion of the Partnership's claims will not be paid in full.
7. Refund of Hushkit Deposits
In 1990, the Partnership agreed to acquire up to 12 hushkits for Boeing 727 aircraft from Federal Express Corporation (Federal Express). Because certain conditions to the purchase of the hushkits were not satisfied, the Partnership requested return of its deposit of $330,000 plus interest as provided in the purchase documents. Federal Express refused the Partnership's request, pending resolution with the Partnership of certain allegedly disputed contractual issues. In April 1992, the general partner, on behalf of the Partnership, commenced legal action to require Federal Express to refund the remaining balance of the deposit, with interest, plus legal fees and other damages, and Federal Express filed a cross-complaint against the Partnership alleging breach of contract. A settlement was reached and payment of the deposit, with interest, was received by the Partnership in November 1992.
8. Related Parties
Under the Partnership Agreement, the Partnership paid or agreed to pay the following amounts to PIMC and/or its affiliates in connection with services rendered:
a. An aircraft management fee equal to 5% of gross rental revenues with respect to operating leases or 2% of gross rental revenues with respect to full payout leases of the Partnership, payable upon receipt of the rent, subordinated to receipt by unit holders of distributions equalling an 8% cumulative, non-compounded return on capital contributions, as defined in the Partnership Agreement.
b. Reimbursement of certain out-of-pocket expenses incurred in connection with the management of the Partnership and supervision of its assets. In 1993, 1992, and 1991, the Partnership reimbursed PIMC for serviced rendered or payments made on behalf of the Partnership of $2,147,152, $584,749, and $433,111, respectively. Reimbursements totalling $477,617 and $38,448 were payable to PIMC at December 31, 1993 and 1992, respectively.
c. A 10% interest in all cash distributions from operations and sales proceeds, gross income in an amount equal to 9.09% of distributed cash available from operations and 1% of net income or loss and taxable income or loss, as such terms are defined in the Partnership Agreement.
d. A subordinated sales commission of 3% of the gross sales price of each aircraft for services performed upon disposition and reimbursement of out-of-pocket and other disposition expenses. Subordinated sales commissions shall be paid only after unit holders have received distributions in an aggregate amount equal to their capital contributions plus a cumulative non-compounded 8% per annum return on their adjusted capital contributions, as defined in the Partnership Agreement. The Partnership did not pay or accrue a sales commission on any aircraft sales to date as the above subordination threshold has not been met.
9. Income Taxes
Federal and state income tax regulations provide that taxes on the income or loss of the Partnership are reportable by the partners in their individual income tax returns. Accordingly, no provision for such taxes has been made in the accompanying financial statements.
In 1993, the Partnership adopted Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS 109). One of the requirements of SFAS 109 is for a public enterprise that is not subject to income taxes, because its income is taxed directly to its owners, to disclose the net difference between
the tax basis and the reported amounts of the enterprise's assets and liabilities.
The net differences between the tax basis and the reported amounts of the Partnership's assets and liabilities at December 31, 1993 are as follows:
Reported Amounts Tax Basis Net Difference
Assets $115,637,336 $87,614,677 $28,022,659
Liabilities 1,047,580 1,302,146 (254,566)
10. Subsequent Events
Sale to Total Aerospace Services, Inc. (Total Aerospace) - In February 1994, the Partnership sold one of the Boeing 727-100 aircraft that was transferred to the Partnership by ATA, as discussed in Note 3, to Total Aerospace for $425,000. The Partnership will record a gain on sale of $425,000 in 1994.
Lease to GB Airways Limited (GB Airways) - In February 1994, the Partnership leased two Boeing 737-200 Advanced aircraft that were formerly on lease to Britannia to GB Airways. Lease payments for an interim lease term through March 1994 are at a variable rate based on usage. Thereafter and through March 1996, the lease rate is 58% of the original rate received from Britannia. The rate is then adjusted through the end of the lease in October 1996 to 67% of the original rate received from Britannia. GB Airways has the option to extend the lease for one year at the initial rate. The lease stipulates that the Partnership share in the cost of certain modification and refurbishment costs which are inestimable at this time.
Lease to TBG Airways Limited (TBG Airways) - In February 1994, the Partnership leased the remaining two Boeing 737-200 Advanced aircraft that were formerly on lease to Britannia to TBG Airways. Lease payments for an interim lease term through April 1994 are at a variable rate based on usage. Thereafter and through the end of the lease in October 1998, the rate is increased annually from 55% to as much as 80% of the original rate received from Britannia. The lease stipulates that the Partnership share in the cost of certain modification and refurbishment costs which are inestimable at this time. TBG Airways has the option to early terminate the lease in April 1997 after paying a termination fee of $250,000. TBG Airways also has the option to purchase the aircraft at the end of the lease term for $8.0 million each.
