Item 1.  Business

General Description of Partnership

         Swift Energy Managed Pension Assets Partnership  1990-A,  Ltd., a Texas
limited  partnership (the "Partnership" or the  "Registrant"),  is a partnership
formed under a public serial  limited  partnership  offering  denominated  Swift
Energy Managed  Pension Assets Fund I  (Registration  Statement No.  33-15998 on
Form S-1, originally declared effective November 13, 1987, and amended effective
November  3,  1988,   August  4,  1989  and  May  1,  1990  [the   "Registration
Statement"]).  The  Partnership  was  formed  effective  April 17,  1990 under a
Limited  Partnership  Agreement  dated April 17,  1990.  The initial 463 limited
partners made capital contributions of $4,305,695.

         The  Partnership  is  principally  engaged in the business of acquiring
nonoperating  interests  (i.e.,  net profits  interests,  royalty  interests and
overriding  royalty  interests)  in proven  oil and gas  properties  within  the
continental United States. The Partnership does not acquire working interests in
or operate oil and gas properties,  and does not engage in drilling  activities.
At December 31, 1996, the  Partnership  had expended or committed to expend 100%
of the limited partners' net commitments  (i.e.,  limited partners'  commitments
available  to  the  Partnership  for  property  acquisitions  after  payment  of
organizational  fees  and  expenses)  in  the  acquisition  and  development  of
nonoperating  interests in producing properties,  which properties are described
under Item 2,  "Properties,"  below. The Partnership's  income is derived almost
entirely from its nonoperating interests and the disposition thereof.

         The  Partnership's  business and affairs are  conducted by its Managing
General  Partner,  Swift Energy  Company,  a Texas  corporation  ("Swift").  The
Partnership's Special General Partner, VJM Corporation, a California corporation
("VJM"), consults with and advises Swift as to certain financial matters.

         The  general  manner in which  the  Partnership  acquires  nonoperating
interests  and  otherwise  conducts  its  business is described in detail in the
Registration Statement under "Proposed Activities," which is incorporated herein
by reference.  The following is intended only as a summary of the  Partnership's
manner of doing business and specific activities to date.

Manner of  Acquiring  Nonoperating  Interests  in  Properties;  Net  Profits and
Overriding Royalty Interest Agreement

         The nonoperating  interests owned by the Registrant have typically been
acquired  pursuant to a Net Profits and Overriding  Royalty  Interest  Agreement
dated April 17, 1990 (the "NP/OR  Agreement")  between the  Registrant and Swift
Energy Income Partners 1990-A, Ltd. (the "Operating Partnership"). The Operating
Partnership  is a Texas  limited  partnership  that is also managed by Swift and
VJM. The Operating  Partnership was formed to acquire and develop  producing oil
and gas properties.

         Under the NP/OR Agreement, the Registrant and the Operating Partnership
have, in effect,  combined their funds to acquire  producing  properties.  Using
funds  committed to the NP/OR  Agreement  by both  partnerships,  the  Operating
Partnership  acquires producing  properties,  then promptly conveys nonoperating
interests therein to the Registrant. The Operating Partnership retains a working
interest in each such property, and is responsible for the production of oil and
gas therefrom. For the sake of legal and administrative  convenience,  producing
properties  are usually  acquired from the third party  sellers by Swift,  which
then  conveys  a  working  interest  in  each  such  property  to the  Operating
Partnership.  The Registrant  initially  committed  $3,707,508 and the Operating
Partnership  initially  committed  $5,222,878 for  acquisitions  under the NP/OR
Agreement.  The Operating  Partnership is obligated under the NP/OR Agreement to
convey to the  Registrant  a 42%  fixed  net  profits  interest  and a  variable
overriding  royalty  interest in specified  depths of all  producing  properties
acquired under the NP/OR Agreement.

         Under the NP/OR  Agreement,  the Operating  Partnership  is required to
convey  to  the  Registrant,   and  the  Registrant  is  required  to  purchase,
nonoperating  interests in all  producing  properties  acquired by the Operating
Partnership, except that:


                                      I-1

          SWIFT ENERGY MANAGED PENSION ASSETS PARTNERSHIP 1990-A, LTD.


                  1. Properties  anticipated to require significant  development
operations and nonoperating  interests  offered to the Operating  Partnership by
third  parties may be purchased by the Operating  Partnership  outside the NP/OR
Agreement, without participation by the Registrant;

                  2. During a  specified  one-year  period,  the  Registrant  is
entitled to reduce the amount originally  committed by it to purchases under the
NP/OR  Agreement  and to redirect  such funds to the  purchase  of  nonoperating
interests from sources other than the Operating Partnership; and

                  3. The  Registrant's  funds  will be  released  from the NP/OR
Agreement if they are not completely spent by the Operating Partnership within a
specified  period,  or if there is a prior  withdrawal of funds by the Operating
Partnership  to  purchase   properties   anticipated   to  require   significant
development.

         Purchases of nonoperating  interests by the Registrant  using withdrawn
or  released  funds  may be made  from  the  Managing  General  Partner  and its
affiliates,   other  partnerships  affiliated  with  the  Operating  Partnership
(possibly through the Registrant's  entry into a new NP/OR  Agreement),  or from
unaffiliated third parties.

         In accordance with its  obligations  under the NP/OR  Agreement,  as of
December 31, 1996 the Operating Partnership had conveyed to the Registrant a 42%
net  profits  interest  burdening  certain  depths of all  producing  properties
acquired  by the  Operating  Partnership  thereunder.  Typically,  a net profits
interest in an oil and gas property entitles the owner to a specified percentage
share of the gross proceeds generated by the burdened property, net of operating
costs.  The net  profits  interest  conveyed to the  Registrant  under the NP/OR
Agreement differs from the typical net profits interest in that it is calculated
over  the  entire  group  of  producing  properties  conveyed  under  the  NP/OR
Agreement; i.e., all operating costs attributable to the burdened depths of such
properties are  aggregated,  and the total is then  subtracted from the total of
all gross  proceeds  attributable  to such depths in order to calculate  the net
profits to which the Registrant is entitled.  The net profits interest  conveyed
to the Registrant  burdens only those depths of each subject property which were
evaluated to contain proved reserves at the date of  acquisition,  to the extent
such depths underlie specified surface acreage.

         The Operating Partnership has also conveyed to the Registrant under the
NP/OR  Agreement  an  overriding  royalty  interests in each  property  acquired
thereunder. An overriding royalty interest is a fractional interest in the gross
production  (or the gross  proceeds  therefrom)  of oil and gas from a property,
free of any exploration,  development,  operation or maintenance expenses. Under
the NP/OR  Agreement,  the overriding  royalty  interest burdens the portions of
each producing  property that were  evaluated at the date of acquisition  not to
contain proved reserves.

Competition, Markets and Regulations

         Competition

         The oil and gas industry is highly  competitive in all its phases.  The
Partnership encounters strong competition from many other oil and gas producers,
many of which possess substantial financial resources, in acquiring economically
desirable Producing Properties.

         Markets

         The amounts of and price  obtainable  for oil and gas  production  from
Partnership  Properties will be affected by market factors beyond the control of
the  Partnership.  Such factors include the extent of domestic  production,  the
level of imports of foreign oil and gas, the general level of market demand on a
regional, national and worldwide basis, domestic and foreign economic conditions
that  determine  levels of industrial  production,  political  events in foreign
oil-producing  regions, and variations in governmental  regulations and tax laws
and  the  imposition  of new  governmental  requirements  upon  the  oil and gas
industry. There can be no assurance that oil and gas prices will not decrease in
the future, thereby decreasing net Revenues from Partnership Properties.


                                      I-2

         From time to time,  there may exist a  surplus  of  natural  gas or oil
supplies,  the effect of which may be to reduce the amount of hydrocarbons  that
the  Partnerships may produce and sell while such oversupply  exists.  In recent
years,  initial steps have been taken to provide  additional gas  transportation
lines from Canada to the United States. If additional Canadian gas is brought to
the United States market, it could create downward pressure on United States gas
prices.

         Regulations

         Environmental Regulation

         The federal  government  and various state and local  governments  have
adopted  laws and  regulations  regarding  the control of  contamination  of the
environment.  These laws and regulations may require the acquisition of a permit
by Operators before drilling commences,  prohibit drilling activities on certain
lands  lying  within  wilderness  areas or where  pollution  arises  and  impose
substantial  liabilities for pollution  resulting from operations,  particularly
operations near or in onshore and offshore waters or on submerged  lands.  These
laws and  regulations  may also  increase  the  costs of  routine  drilling  and
operation of wells.  Because these laws and regulations change  frequently,  the
costs to the  Partnership of compliance  with existing and future  environmental
regulations cannot be predicted.  However, the Managing Partner does not believe
that the  Partnership is affected in a significantly  different  manner by these
regulations than are its competitors in the oil and gas industry.

         Federal Regulation of Natural Gas

         The  transportation  and sale of natural gas in interstate  commerce is
heavily  regulated  by  agencies  of  the  federal  government.   The  following
discussion is intended only as a summary of the principal statutes,  regulations
and  orders  that  may  affect  the  production  and  sale of  natural  gas from
Partnership  Properties.  This  summary  should not be relied upon as a complete
review of applicable natural gas regulatory provisions.

         FERC Orders

         Several major  regulatory  changes have been implemented by the Federal
Energy Regulatory  Commission  ("FERC") from 1985 to the present that affect the
economics of natural gas production,  transportation and sales. In addition, the
FERC  continues  to  promulgate  revisions  to various  aspects of the rules and
regulations  affecting  those  segments of the natural gas industry  that remain
subject to the FERC's jurisdiction. In April 1992, the FERC issued Order No. 636
pertaining to pipeline restructuring. This rule requires interstate pipelines to
unbundle  transportation  and sales services by separately  stating the price of
each service and by providing  customers  only the particular  service  desired,
without  regard to the source for  purchase of the gas.  The rule also  requires
pipelines to (i) provide  nondiscriminatory  "no-notice"  service  allowing firm
commitment  shippers to receive  delivery of gas on demand up to certain  limits
without  penalties,  (ii) establish a basis for release and reallocation of firm
upstream  pipeline  capacity  and  (iii)  provide  non-discriminatory  access to
capacity by firm  transportation  shippers on a  downstream  pipeline.  The rule
requires interstate  pipelines to use a straight fixed variable rate design. The
rule imposes these same requirements upon storage facilities.

         FERC Order No. 500  affects the  transportation  and  marketability  of
natural gas.  Traditionally,  natural gas has been sold by producers to pipeline
companies,  which then  resold the gas to  end-users.  FERC Order No. 500 alters
this market structure by requiring  interstate  pipelines that transport gas for
others to provide  transportation  service to  producers,  distributors  and all
other shippers of natural gas on a nondiscriminatory, "first-come, first-served"
basis ("open access  transportation"),  so that producers and other shippers can
sell natural gas directly to end-users.  FERC Order No. 500 contains  additional
provisions intended to promote greater competition in natural gas markets.

         It is not anticipated  that the  marketability  of and price obtainable
for natural gas production from  Partnership  Properties  will be  significantly
affected  by FERC  Order No.  500.  Gas  produced  from  Partnership  Properties
normally  will be sold to  intermediaries  who have entered into  transportation
arrangements with pipeline companies.  These  intermediaries will accumulate gas
purchased from a number of producers and sell the gas to end-users  through open
access pipeline transportation.

         State Regulations

         Production  of any oil  and gas  from  Partnership  Properties  will be
affected  to some  degree  by  state  regulations.  Many  states  in  which  the
Partnership will operate have statutory provisions regulating the production and
sale  of oil  and  gas,  including  provisions  regarding  deliverability.  Such
statutes, and the regulations promulgated in connection therewith, are generally
intended to prevent  waste of oil and gas and to protect  correlative  rights to
produce  oil and  gas  between  owners  of a  common  reservoir.  Certain  state
regulatory  authorities  also  regulate  the amount of oil and gas  produced  by
assigning allowable rates of production to each well or proration unit.

         Federal Leases

         Some of the Partnership's properties are located on federal oil and gas
leases  administered by various federal  agencies,  including the Bureau of Land
Management.   Various  regulations  and  orders  affect  the  terms  of  leases,
exploration and development plans, methods of operation and related matters.

Employees

         The  Partnership  has no  employees.  Swift,  however,  has a staff  of
geologists,   geophysicists,   petroleum  engineers,   landmen,  and  accounting
personnel who  administer  the  operations of Swift and the  Partnership.  As of
December 31, 1996, Swift had 191 employees.  Swift's administrative and overhead
expenses  attributable  to  the  Partnership's   operations  are  borne  by  the
Partnership.

Item 2.  Nonoperating Interests in Properties

         As of December  31, 1996,  the  Partnership  has acquired  nonoperating
interests in producing  oil and gas  properties  which are  generally  described
below.

Principal Oil and Gas Producing Properties

         The most  valuable  fields  in the  Partnership,  based  upon  year-end
engineering  estimates of discounted  future net revenues using constant pricing
and costs, are described below.

         1. The Weatherford Field is in Custer County,  Oklahoma in the Anadarko
Basin (Amoco acquisition).  The Weatherford Field produces primarily natural gas
and condensate and accounts for 70% of the value.

         The remaining  value in the  Partnership  is  attributable  to numerous
properties  none of which equals or exceeds 15 percent of the total  Partnership
value.

Title to Properties

         Title to substantially  all significant  producing  properties in which
the Partnership owns  nonoperating  interests has been examined.  In addition to
the nonoperating interests owned by the Partnership,  the properties are subject
to royalty,  overriding  royalty and other interests  customary in the industry.
The Managing  General  Partner does not believe any of these burdens  materially
detract from the value of the  properties  or will  materially  detract from the
value of the properties or materially  interfere with their use in the operation
of the business of the Partnership.

Production and Sales Price

         The following table  summarizes the sales volumes of the  Partnership's
net oil and gas production  expressed in MCFs.  Equivalent  MCFs are obtained by
converting oil to gas on the basis of their relative energy content;  one barrel
equals 6,000 cubic feet of gas.

</TABLE>


         There are numerous  uncertainties  inherent in estimating quantities of
proved  reserves and in projecting  the future rates of  production,  timing and
plan of  development.  Oil and gas reserve  engineering  must be recognized as a
subjective process of estimating  underground  accumulations of oil and gas that
cannot be measured  in an exact way,  and  estimates  of other  engineers  might
differ  from  those  above,  audited  by H. J.  Gruy and  Associates,  Inc.,  an
independent petroleum consulting firm. The accuracy of any reserve estimate is a
function of the quality of  available  data and of  engineering  and  geological
interpretation  and  judgment.  Results  of  drilling,  testing  and  production
subsequent  to the date of the estimate may justify  revision of such  estimate,
and, as a general rule,  reserve  estimates based upon  volumetric  analysis are
inherently  less  reliable  than  those  based on  lengthy  production  history.
Accordingly,  reserve  estimates are often  different from the quantities of oil
and gas that are ultimately recovered.

         In estimating  the oil and natural gas  reserves,  the  Registrant,  in
accordance with criteria  prescribed by the Securities and Exchange  Commission,
has used prices received as of December 31, 1996 without  escalation,  except in
those instances where fixed and determinable  gas price  escalations are covered
by  contracts,  limited  to the  price the  Partnership  reasonably  expects  to
receive.  The  Registrant  does not believe that any  favorable or adverse event
causing a significant  change in the estimated  quantity of proved  reserves has
occurred between December 31, 1996 and the date of this report.

         Future prices received for the sale of the  Partnership's  products may
be higher or lower than the prices used in the evaluation  described  above; the
operating  costs relating to such  production may also increase or decrease from
existing  levels.  The estimates  presented  above are in accordance  with rules
adopted by the Securities and Exchange Commission.

Item 5.  Market Price of and Distributions on the Registrant's Units and Related
         Limited Partner Matters

Market Information

         Units in the  Partnership  were  initially  sold at a price of $100 per
Unit.  Units are not traded on any exchange and there is no  established  public
trading  market for the Units.  Swift is aware of negotiated  transfers of Units
between  unrelated  parties;  however,  these  transfers  have been  limited and
sporadic.  Due to the  nature of these  transactions,  Swift  has no  verifiable
information regarding prices at which Units have been transferred.

Holders

         As of December 31, 1996,  there were 463 Limited Partners holding Units
in the Partnership.

Distributions

         The Partnership  generally makes distributions to Limited Partners on a
quarterly  basis,   subject  to  the  restrictions  set  forth  in  the  Limited
Partnership Agreement. In the fiscal years ended December 31, 1995 and 1996, the
Partnership distributed a total of $233,700 and $153,900,  respectively,  to the
holders of its Units.  Cash  distributions  constitute net proceeds from sale of
oil and gas  production  after  payment of lease  operating  expenses  and other
partnership expenses.  Some or all of such amounts or any proceeds from the sale
of partnership  properties  could be deemed to constitute a return of investors'
capital.

         Oil and gas  investments  involve a high risk of loss, and no assurance
can be given that any particular  level of distributions to holders of Units can
be  achieved  or  maintained.   Although  it  is   anticipated   that  quarterly
distributions  will continue to be made through 1997, the Partnership's  ability
to make distributions  could be diminished by any event adversely  affecting the
oil and gas properties in which the Partnership  owns interests or the amount of
revenues received by the Partnership therefrom.

         The  Partnership's   Limited  Partnership  Agreement  contains  various
provisions  which might serve to delay,  defer or prevent a change in control of
the Partnership,  such as the requirement of a vote of Limited Partners in order
to  sell  all  or  substantially  all  of the  Partnership's  properties  or the
requirement of consent by the Managing  General  Partner to transfers of limited
partnership interests.

Item 7. Management's Discussion and Analysis of Financial Condition
        and Results of Operations

Liquidity and Capital Resources

         The  Partnership  has expended  all of the  partners'  net  commitments
available for property  acquisitions  and development by acquiring  nonoperating
interests in producing oil and gas properties. The partnership invests primarily
in  proved  producing   properties  with  nominal  levels  of  future  costs  of
development  for proven  but  undeveloped  reserves.  Significant  purchases  of
additional reserves or extensive drilling activity are not anticipated.  Oil and
gas reserves are depleting  assets and therefore  often  experience  significant
production  declines each year from the date of  acquisition  through the end of
the life of the  property.  The primary  source of liquidity to the  Partnership
comes almost entirely from the income generated from  nonoperating  interests in
oil and gas produced from oil and gas  properties.  This source of liquidity and
the related  results of operations will decline in future periods as the oil and
gas produced from these properties also declines.

Results of Operations

         Income from nonoperating  interests  increased 47  percent in 1996 over
1995. Oil and gas sales increased 24 percent in 1996 vs. 1995. Increases in both
1996 gas and oil prices were major contributors to the increased  revenues.  The
Partnership  experienced an increase in gas prices of 51 percent or $.76/MCF and
an  increase  in oil  prices of 25  percent  or  $3.98/BBL.  Production  volumes
decreased 20 percent due to a 47 percent oil production decrease and a 4 percent
gas production  decline.  The production declines partially offset the effect of
increased oil and gas prices impacting partnership performance.

         Associated  amortization  expense  decreased  8  percent  in 1996 when
compared to 1995.

         Income from  nonoperating  interests  decreased 33 percent in 1995 over
1994.  Oil and gas sales  decreased  26  percent  in 1995 vs.  1994.  Production
volumes decreased 21 percent due to a 25 percent gas production decrease.  Since
the  Partnership's  reserves are 86 percent gas, the decrease in gas production,
due  to  accelerated  production  declines  on  mature  wells,  a  reduction  in
development  drilling in the current  year and  production  curtailments  due to
declining prices,  had a major impact on partnership  performance.  A decline in
the 1995 gas  prices  of 17  percent  or  $.30/MCF  further  contributed  to the
Partnership's decreased revenues.

         Associated  amortization  expense  decreased  21  percent  in 1995 when
compared to 1994.

         The  Partnership  recorded an additional  provision in  amortization in
1995 and 1994 when the present  value,  discounted at ten percent,  of estimated
future net revenues  from oil and gas  properties,  using the  guidelines of the
Securities and Exchange  Commission,  was below the fair market value originally
paid for oil and gas properties, resulting in a full cost ceiling impairment.

         During 1997,  Partnership revenues and costs will be shared between the
limited partners and general partners in an 90:10 ratio, based on the annualized
rate of cash  distributions by the Partnership  during a certain period prior to
December 31, 1996.  Based on current oil and gas prices,  current  levels of oil
and gas  production  and expected cash  distributions  during 1997, the Managing
General Partner  anticipates that the Partnership sharing ratio will continue to
be 90:10.

         From time to time, Swift as Managing General Partner of the Partnership
purchases Units in the  Partnership  from investors who offer the Units pursuant
to their right of  presentment,  which  purchases are made pursuant to terms set
out in the  Partnership's  original Limited  Partnership  Agreement.  Due to the
frequency  and  large  number  of  these   transactions,   Swift  reports  these
transactions  under  Section  16 of the  Securities  Exchange  Act of 1934 on an
annual  rather than a monthly  basis.  In some cases such annual  reporting  may
constitute a late filing of the required Section 16 reports under the applicable
Section 16 rules.

Item 11.  Executive Compensation

         As  noted  in  Item  10,  "Directors  and  Executive  Officers  of  the
Registrant,"  above,  the Partnership has no executive  officers.  The executive
officers of Swift and VJM are not compensated by the Partnership.

         Certain fees and  allowances  contemplated  by the Limited  Partnership
Agreement  have been paid by the  Partnership  to Swift and VJM. See Note (4) in
Notes  To  Financial   Statements   (Related-Party   Transactions)  for  further
discussion.

Item 12.  Security Ownership of Certain Beneficial Owners and Management

         No  single  limited  partner  is  known  to the  Partnership  to be the
beneficial owner of more than five percent of the Partnership's Units.

         Swift and VJM are not aware of any arrangement,  the operation of which
may at a subsequent date result in a change in control of the Partnership.

Item 13.  Certain Relationships and Related Transactions

         As  noted  in  Item  10,  "Directors  and  Executive  Officers  of  the
Registrant," above, the Partnership has no executive officers or directors,  and
thus has not  engaged  in any  transactions  in which  any  such  person  had an
interest.  The Partnership is permitted to engage in certain  transactions  with
Swift as Managing General Partner and VJM as Special General Partner, subject to
extensive  guidelines  and  restrictions  are  described  in the  "Conflicts  of
Interest"  section  of the  Amended  Prospectus  contained  in the  Registration
Statement, which is incorporated herein by reference.

         Summarized  below are the  principal  transactions  that have  occurred
between the Partnership,  on one hand, and Swift, VJM and their  affiliates,  on
the other.

Certain Transactions with General Partners

         1.  As  described  in  Item  1,  "Business,"  above,  during  1990  the
Partnership  entered into an NP/OR  Agreement  with the  Operating  Partnership,
which is also managed by Swift and VJM.  Pursuant to such NP/OR  Agreement,  the
Operating Partnership acquired the oil and gas properties described under Item 2
above and conveyed nonoperating interests therein to the Partnership.

         2.  Swift  acts  as  operator  for  many  of the  wells  in  which  the
Partnership has  nonoperating  interests and has received  compensation for such
activities in accordance with standard industry operating agreements.

         3.  The Partnership  paid to Swift and VJM certain fees as contemplated
by the  Limited  Partnership  Agreement.  See Note  (4) in  Notes  To  Financial
Statements (Related-Party Transactions) for further discussion.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Swift Energy Managed Pension Assets Partnership 1990-A, Ltd.:

         We have audited the accompanying balance sheets of Swift Energy Managed
Pension Assets  Partnership  1990-A,  Ltd., (a Texas limited  partnership) as of
December 31, 1996 and 1995, and the related statements of operations,  partners'
capital and cash flows for the years ended  December  31,  1996,  1995 and 1994.
These  financial  statements  are the  responsibility  of the general  partner's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

         We conducted our audits in accordance with generally  accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion,  the  financial  statements  referred to above  present
fairly, in all material respects, the financial position of Swift Energy Managed
Pension Assets  Partnership  1990-A,  Ltd., as of December 31, 1996and 1995, and
the results of its  operations  and its cash flows for the years ended  December
31, 1996,  1995 and 1994,  in  conformity  with  generally  accepted  accounting
principles.

          SWIFT ENERGY MANAGED PENSION ASSETS PARTNERSHIP 1990-A, LTD.
                          NOTES TO FINANCIAL STATEMENTS


(1) Organization and Terms of Partnership Agreement -

         Swift Energy Managed Pension Assets Partnership  1990-A,  Ltd., a Texas
limited  partnership  (the  Partnership),  was formed on April 17, 1990, for the
purpose of purchasing net profits  interests,  overriding  royalty interests and
royalty interests (collectively,  "nonoperating interests") in producing oil and
gas  properties  within the  continental  United  States.  Swift Energy  Company
("Swift"),  a Texas  corporation,  and VJM  Corporation  ("VJM"),  a  California
corporation,  serve as Managing  General  Partner and Special General Partner of
the Partnership,  respectively.  The general partners are required to contribute
up to 1/99th of limited partner net contributions. The 463 limited partners made
total capital contributions of $4,305,695.

         Nonoperating  interests  acquisition  costs and the  management fee are
borne  99  percent  by the  limited  partners  and one  percent  by the  general
partners.  Organization  and syndication  costs were borne solely by the limited
partners.

         Initially,  all continuing costs (including  general and administrative
reimbursements and direct expenses) and revenues are allocated 90 percent to the
limited  partners  and  ten  percent  to  the  general  partners.  If  prior  to
partnership payout, as defined,  however, the cash distribution rate (as defined
in the  Partnership  Agreement)  for a certain  period  equals or  exceeds  17.5
percent,  then for the  following  calendar  year,  these  continuing  costs and
revenues will be allocated 85 percent to the limited  partners and 15 percent to
the general partners.  After partnership  payout,  continuing costs and revenues
will be shared 85 percent by the limited partners, and 15 percent by the general
partners,  even if the cash distribution rate is less than 17.5 percent.  During
1993, 1992 and 1991, the cash  distribution rate exceeded 17.5 percent and thus,
in 1994, 1993 and 1992, the continuing costs and revenues were shared 85 percent
by the limited  partners  and 15 percent by the general  partners.  During 1996,
1995 and 1994, the cash  distribution  rate fell below 17.5 percent and thus, in
1997, 1996 and 1995, the continuing  costs and revenues will be (were) shared 90
percent by the limited partners and 10 percent by the general  partners.  Payout
had not occurred as of December 31, 1996.

(2) Significant Accounting Policies -

Use of Estimates --

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the reported  amounts of assets and  liabilities at the
date of the  financial  statements  and the  reported  amounts of  revenues  and
expenses  during  the  reporting  period.   Actual  results  could  differ  from
estimates.

Nonoperating Interests in Oil and Gas Properties --

         For  financial   reporting   purposes,   the  Partnership  follows  the
"full-cost"  method of  accounting  for  nonoperating  interests  in oil and gas
properties.  Under  this  method  of  accounting,  all  costs  incurred  in  the
acquisition of nonoperating interests in oil and gas properties are capitalized.
The  unamortized  cost of  nonoperating  interests in oil and gas  properties is
limited to the "ceiling limitation", (calculated separately for the Partnership,
limited partners, and general partners).  The "ceiling limitation" is calculated
on a quarterly  basis and  represents  the  estimated  future net revenues  from
nonoperating interests in proved properties using current prices,  discounted at
ten percent.  Proceeds from the sale or disposition of nonoperating interests in
oil  and  gas  properties  are  treated  as a  reduction  of  the  cost  of  the
nonoperating  interests with no gains or losses recognized except in significant
transactions.

         The Partnership computes the provision for amortization of nonoperating
interests in oil and gas  properties on the  units-of-production  method.  Under
this method,  the provision is calculated by multiplying  the total  unamortized
cost of  nonoperating  interests  in oil and gas  properties  by an overall rate
determined  by dividing  the physical  units of oil and gas produced  during the
period by the total estimated units of proved oil and gas reserves  attributable
to the Partnership's nonoperating interests at the beginning of the period.


                                      IV-8


<PAGE>

          SWIFT ENERGY MANAGED PENSION ASSETS PARTNERSHIP 1990-A, LTD.
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)


         The  calculation  of the "ceiling  limitation"  and the  provision  for
amortization  is based on  estimates  of proved  reserves.  There  are  numerous
uncertainties  inherent  in  estimating  quantities  of proved  reserves  and in
projecting the future rates of production,  timing and plan of development.  The
accuracy of any reserve  estimate is a function of the quality of available data
and of  engineering  and  geological  interpretation  and  judgment.  Results of
drilling,  testing and  production  subsequent  to the date of the  estimate may
justify  revision of such  estimate.  Accordingly,  reserve  estimates are often
different from the quantities of oil and gas that are ultimately recovered.

Statements of Cash Flows --

         Highly liquid debt instruments with an initial maturity of three months
or less are considered to be cash equivalents.

(3) Acquisition of Nonoperating Interests in Oil and Gas Property Costs -

         Effective  April 17, 1990, the  Partnership  entered into a Net Profits
and Overriding  Royalty Interests  Agreement (NP/OR Agreement) with Swift Energy
Income Partners 1990-A, Ltd. (Operating Partnership),  managed by Swift, for the
purpose of acquiring  interests in producing oil and gas  properties.  Under the
terms of the NP/OR  Agreement,  the Partnership has been conveyed a nonoperating
interest in the  aggregate net profits  (i.e.,  oil and gas sales net of related
operating costs) of the properties  acquired equal to its proportionate share of
the property  acquisition  costs,  as defined.  Property  acquisition  costs are
amounts actually paid by the Operating Partnership for the properties plus costs
incurred by the  Operating  Partnership  in acquiring the  properties  and costs
related to screening and  evaluation of properties not acquired.  In 1996,  1995
and 1994, the Partnership acquired  nonoperating  interests in producing oil and
gas properties for $39,258, $134,629 and $100,318, respectively.

         During  1995  and  1994,  the  Partnership's  unamortized  oil  and gas
property costs exceeded the quarterly  calculations of the "ceiling  limitation"
resulting in an additional  provision for  amortization of $335,628 and $96,094.
No such write downs were  required in 1996.In  addition,  the limited  partners'
share  of  unamortized  oil and  gas  property  costs  exceeded  their  "ceiling
limitation" in 1995 and 1994, resulting in a valuation allowance of $285,870 and
$227,693,   respectively.   This  amount  is  included  in  the  income   (loss)
attributable to the limited partners shown in the statement of partners' capital
together with a "combining  adjustment"  for the difference  between the limited
partners' valuation  allowance and the Partnership's  valuation  allowance.  The
"combining adjustment" changes quarterly as the Partnership's total amortization
provision is more or less than combined amortization  provision  attributable to
general and limited partners.

(4) Related-Party Transactions -

         An  affiliate  of the  Special  General  Partner,  as  Dealer  Manager,
received   $107,392  for  managing  and   overseeing  the  offering  of  limited
partnership units.

         A one-time  management  fee of  $107,642  was paid to Swift in 1990 for
services  performed  for the  Partnership.  During  1996,  1995  and  1994,  the
Partnership paid Swift $64,585, $64,585 and $64,585,  respectively, as a general
and administrative overhead allowance.

(5) Federal Income Taxes -

         The Partnership is not a tax-paying entity. No provision is made in the
accounts of the Partnership for federal or state income taxes,  since such taxes
are liabilities of the individual partners,  and the amounts thereof depend upon
their respective tax situations.

         The tax returns and the amount of distributable  Partnership income are
subject to  examination  by the federal  and state  taxing  authorities.  If the
Partnership's  royalty  income for federal  income tax  purposes  is  ultimately
changed by the taxing  authorities,  the tax  liability of the limited  partners
could be changed  accordingly.  Royalty  income  reported  on the  Partnership's
federal  return of income for the years ended  December 31, 1996,  1995 and 1994
was  $667,167,  $113,056 and  $496,394,  respectively.  The  difference  between
royalty income for federal income tax purposes  reported by the  Partnership and
income or loss from  nonoperating  interests  reported herein primarily  results
from the exclusion of  amortization  (as described  below) from ordinary  income
reported in the Partnership's federal return of income.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)


         For  federal  income  tax  purposes,   amortization   with  respect  to
nonoperating  interests in oil and gas properties is computed  separately by the
partners  and not by the  Partnership.  Since  the  amount  of  amortization  on
nonoperating  interests in oil and gas is not computed at the Partnership level,
amortization is not included in the Partnership's  income for federal income tax
purposes but is charged directly to the partners' capital accounts to the extent
of the cost of the nonoperating interests in oil and gas properties, and thus is
treated as a separate  item on the  partners'  Schedule  K-1.  Amortization  for
federal income tax purposes may vary from that computed for financial  reporting
purposes in cases where a ceiling adjustment is recorded,  as such amount is not
recognized for tax purposes.

(6) Vulnerability Due to Certain Concentrations -

         The Partnership's revenues are primarily the result of sales of its oil
and natural gas  production.  Market prices of oil and natural gas may fluctuate
and adversely affect operating results.

         The Partnership  extends credit to various companies in the oil and gas
industry which results in a concentration of credit risk. This  concentration of
credit risk may be affected by changes in economic or other  conditions  and may
accordingly impact the Partnership's  overall credit risk. However, the Managing
General Partner believes that the risk is mitigated by the size, reputation, and
nature of the companies to which the Partnership  extends  credit.  In addition,
the  Partnership  generally  does not require  collateral  or other  security to
support customer receivables.

(7) Fair Value of Financial Instruments -

         The  Partnership's  financial  instruments  consist  of cash  and  cash
equivalents  and  short-term  receivables  and  payables.  The carrying  amounts
approximate  fair  value  due to the  highly  liquid  nature  of the  short-term
instruments.
