THE FOLLOWING TEXT IS ADDED TO THE END OF SECTION 2 "ANNUITY INCOME OPTIONS" OF
THE PROSPECTUS:
 
THE INCOME PROTECTOR
 
This feature provides a future "safety net" in the event that, when you choose
to begin receiving income payments, your contract has not performed within a
historically anticipated range. The Income Protector feature offers you the
ability to receive a guaranteed fixed minimum retirement income upon
annuitization. With the Income Protector you can know the level of minimum
income that will be available to you if, when you chose to retire, down markets
have negatively impacted your contract value. To annuitize using this feature
you must follow the appropriate steps set forth below.
 
The Income Protector provides three alternative levels of minimum retirement
income. The Base Income Protector is a standard feature of all Polaris(II)
contracts issued after November 2, 1998, if the feature is available for sale in
your state. There is no additional charge associated with the Base feature. If
elected, The Income Protector Plus and Income Protector Max alternatives can
provide increased levels of minimum guaranteed income. We charge a fee for each
of these alternatives. The amount of the fee and how to select an alternative
level of income protection, if that is appropriate for you, is described below.
 
HOW WE DETERMINE THE AMOUNT OF YOUR MINIMUM GUARANTEED INCOME
 
We base the amount of minimum income available to you if you annuitize using the
Income Protector upon a calculation we call the Income Benefit Base. At the time
your participation in the Income Protector program becomes effective, your
Income Benefit Base is equal to your contract value. For the Base, participation
is effective on the date of issue of your contract. For the Plus or Max
alternatives, participation is effective on either the date of issue of the
contract (if elected) or at the contract anniversary following your election of
the Plus or Max alternative.
 
The Income Benefit Base is only a calculation. It does not represent a contract
value, nor does it guarantee performance of the variable Portfolios in which you
invest.
 
Your Income Benefit Base increases if you make subsequent Purchase Payments and
decreases if you withdraw money from your contract. The exact Income Benefit
Base calculation is equal to (a) plus (b) minus (c) where:
 
     (a) is,
 
        - for the first year of calculation, your contract value on the date
          your participation in the program becomes effective, and;
 
        - for each subsequent year of calculation, the Income Benefit Base on
          the prior contract anniversary, and;
 
     (b) is the sum of all subsequent Purchase Payments made into the contract
         since the last contract anniversary, and;
 
     (c) is all withdrawals and applicable fees and charges since the last
         contract anniversary, in an amount proportionate to the amount by which
         such withdrawals decreased your contract value.
 
For the Plus or Max alternatives, the Income Benefit Base accumulates at one of
the following annual growth rates from the date your election in the alternative
becomes effective through your Income Benefit Date (see below):

CHOOSING THE APPROPRIATE LEVEL OF PROTECTION FOR YOU
 
If you decide that you want the protection offered by the Income Protector Plus
or Max feature, you must elect the alternative by completing the Income
Protector Election Form available through our Annuity Service Center. You may
only elect one of the alternatives and you can never change your election once
made. Your Income Benefit Base will begin accumulating at the applicable growth
rate on the contract anniversary following our receipt of your completed
election form. In order to obtain the benefit of the Plus or Max alternative you
may not begin the Income Phase for at least seven years following your election
of the Plus or Max feature. Thus, you must make your election prior to the later
of:
 
     - your 83rd birthday, or
 
     - your 3rd contract anniversary.
 
STEP-UP OF YOUR INCOME BENEFIT BASE
 
If you have elected to pay for the higher levels of protection available through
the Income Protector Plus or Max, you may also have the opportunity to "Step-Up"
your Income Benefit Base. The Step-Up feature allows you to increase your Income
Benefit Base to the amount of your contract value on your contract anniversary.
You can only elect to Step-Up within the 30 days before your next contract
anniversary. A seven year waiting period required prior to electing annuity
payments through the Income Protector is restarted if you step-up your Income
Benefit Base. Thus, your last opportunity to step up is the later of :
 
     - your 83rd birthday, or
 
     - your 3rd contract anniversary.
 
You must complete the Income Protector Election Form to effect a Step-Up. The
form is available from our Annuity Service Center.
 
ELECTING TO RECEIVE INCOME PAYMENTS
 
You may elect to begin the Income Phase of your contract using the Income
Protector Program ONLY within the 30 days after the seventh or later contract
anniversary following the later of,
 
     - the effective date of your Income Protector participation, or
 
     - the contract anniversary of your most recent Step-Up.
 
The contract anniversary of, or prior to, your election to begin receiving
annuity payments is your Income Benefit Date. This is the date as of which we
calculate your Income Benefit Base to use in determining your guaranteed minimum
fixed retirement income. To arrive at the minimum guaranteed retirement income
available to you we apply the annuity rates stated in your Income Protector
Endorsement for the annuity option you select to your final Income Benefit Base.
You then choose if you would like to receive that income annually, quarterly or
monthly for the time guaranteed under your selected annuity option. Your final
Income Benefit Base is equal to (a) minus (b) where:
 
     (a) is your Income Benefit Base as your Income Benefit Date, and;
 
     (b) is any partial withdrawals of contract value and any charges applicable
         to those withdrawals and any withdrawal charges otherwise applicable,
         calculated as if you fully surrender your contract as of the Income
         Benefit Date, and any applicable premium taxes.
 
The annuity options available when using the Income Protector Program to receive
your fixed retirement income are:
 
     - Life Annuity with 10 Year Period Certain, or
 
     - Joint and 100% Survivor Annuity with 20 Year Period Certain
 
At the time you elect to begin receiving annuity payments, we will calculate
your annual income using both your final Income Benefit Base and your contract
value. We will use the same income option for each calculation, however, the
annuity factors used to calculate your income under the Income Protector will be
different. You will receive whichever provides a greater stream of income. If
you annuitize using the Income Protector your income payments will be fixed in
amount. You are not required to use the Income Protector to receive income
payments. However, we will not refund fees paid for the Income

Protector if you annuitize under the general provisions of your contract. YOU
MAY NEVER NEED TO RELY UPON THE INCOME PROTECTOR, IF YOUR CONTRACT PERFORMS
WITHIN A HISTORICALLY ANTICIPATED RANGE. HOWEVER, PAST PERFORMANCE IS NO
GUARANTEE OF FUTURE RESULTS.
 
FEES ASSOCIATED WITH THE INCOME PROTECTOR
 
The Base Income Protector is a standard feature of your contract at no extra
charge. If you elect the Income Protector Plus or Max, we charge a fee, as
follows:
 
- --------------------------------------------------------------------------------
 
<TABLE>

                    ALTERNATIVE                           FEE AS A % OF YOUR INCOME BENEFIT BASE

               Income Protector Plus                                       .15%

               Income Protector Max                                        .30%
- -------------------------------------------------------------------------------------------------------
</TABLE>
 
Since the Income Benefit Base is only a calculation and does not provide a
contract value, we deduct the fee from your actual contract value beginning on
the contract anniversary on which your participation in the program becomes
effective.
 
After a Step-Up, the fee for the Income Protector Max or Plus will be based on
your Stepped-Up Income Benefit Base, and will be deducted from your contract
value beginning on the effective date of the step-up.
 
If your contract is issued with the Income Protector program, and you elect the
Plus or Max alternative (either at contract issue or some later date) we begin
deducting the annual fee for the Plus or Max alternative on the contract
anniversary when your alternative election becomes effective. If your contract
is not issued with the Income Protector program and you elect the Plus or Max
alternative at some later date, we begin deducting the annual fee on the
contract anniversary following the date on which your participation in the
program becomes effective.
 
It is important to note that once you elect either alternative, you may not
cancel your election. We will deduct the charge from your contract value on
every contract anniversary up to and including your Income Benefit Date.
Additionally, we deduct the full annual fee from any full surrender of your
contract requested prior to your contract anniversary based on the Income
Benefit Base at time of surrender.
 
NOTE TO QUALIFIED CONTRACT HOLDERS
 
Qualified contracts generally require that you select an income option which
does not exceed your life expectancy. That restriction, if it applies to you,
may limit the benefit of the Income Protector program. As discussed above, in
order to utilize the Income Protector you must annuitize under one of two income
options. If those income options exceed your life expectancy you may be
prohibited from receiving your guaranteed fixed income under the program. If you
own a Qualified contract to which this restriction applies and you elect the
Income Protector Max or Plus, you may pay for this guarantee and not be able to
realize the benefit.
 
Generally,
 
     - for the Life Annuity with 10 Year Period Certain, you must annuitize
       before age 79, and
 
     - for the Joint and 100% Survivor Annuity with 20 Year Period Certain, both
       Annuitants must be 70 or younger or one of the annuitants must be 65 or
       younger upon annuitization. Other age combinations may be available.
 
You may wish to consult your tax advisor for information concerning your
particular circumstances.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
Management's discussion and analysis of financial condition and results of
operations of Anchor National Life Insurance Company (the "Company") for the
three years in the period ended September 30, 1997 follows. In connection with
the "safe harbor" provisions of the Private Securities Litigation Reform Act of
1995, the Company cautions readers regarding certain forward-looking statements
contained in this report and in any other statements made by, or on behalf of,
the Company, whether or not in future filings with the Securities and Exchange
Commission (the "SEC"). Forward-looking statements are statements not based on
historical information and which relate to future operations, strategies,
financial results, or other developments. Statements using verbs such as
"expect," "anticipate," "believe" or words of similar import generally involve
forward-looking statements. Without limiting the foregoing, forward-looking
statements include statements which represent the Company's beliefs concerning
future levels of sales and redemptions of the Company's products, investment
spreads and yields, or the earnings and profitability of the Company's
activities.
 
Forward-looking statements are necessarily based on estimates and assumptions
that are inherently subject to significant business, economic and competitive
uncertainties and contingencies, many of which are beyond the Company's control
and many of which are subject to change. These uncertainties and contingencies
could cause actual results to differ materially from those expressed in any
forward-looking statements made by, or on behalf of, the Company. Whether or not
actual results differ materially from forward-looking statements may depend on
numerous foreseeable and unforeseeable developments. Some may be national in
scope, such as general economic conditions, changes in tax law and changes in
interest rates. Some may be related to the insurance industry generally, such as
pricing competition, regulatory developments and industry consolidation. Others
may relate to the Company specifically, such as credit, volatility and other
risks associated with the Company's investment portfolio. Investors are also
directed to consider other risks and uncertainties discussed in documents filed
by the Company with the SEC. The Company disclaims any obligation to update
forward-looking information.
 
RESULTS OF OPERATIONS FOR THE YEARS 1995, 1996 AND 1997
 
NET INCOME totaled $63.1 million in 1997, compared with $45.1 million in 1996
and $39.3 million in 1995.
 
PRETAX INCOME totaled $94.3 million in 1997, $69.3 million in 1996 and $65.0
million in 1995. The 36.1% improvement in 1997 over 1996 primarily resulted from
increased fee income and net investment income, partially offset by higher
general and administrative expenses and increased amortization of deferred
acquisition costs. The 6.6% improvement in 1996 over 1995 primarily resulted
from increased net investment income and significantly increased fee income,
partially offset by increased net realized investment losses and additional
general and administrative expenses.
 
NET INVESTMENT INCOME, which is the spread between the income earned on invested
assets and the interest paid on fixed annuities and other interest-bearing
liabilities, increased to $73.2 million in 1997 from $56.8 million in 1996 and
$50.1 million in 1995. These amounts equal 2.77% on average invested assets
(computed on a daily basis) of $2.65 billion in 1997, 2.59% on average invested
assets of $2.19 billion in 1996 and 2.95% on average invested assets of $1.70
billion in 1995.
 
Net investment spreads include the effect of income earned on the excess of
average invested assets over average interest-bearing liabilities. This excess
amounted to $126.5 million in 1997, $142.9 million in 1996 and $108.4 million in
1995. The difference between the Company's yield on average invested assets and
the rate paid on average interest-bearing liabilities (the "Spread Difference")
was 2.51% in 1997, 2.25% in 1996 and 2.63% in 1995.
 
Investment income (and the related yields on average invested assets) totaled
$210.8 million (7.97%) in 1997, compared with $164.6 million (7.50%) in 1996 and
$129.5 million (7.62%) in 1995. These increased yields in 1997 include the
effects of a greater proportion of mortgage loans in the Company's portfolio. On
average, mortgage loans have higher yields than that of the Company's overall
portfolio. In addition, the Company experienced higher returns on its
investments in partnerships. The increases in investment income in 1997 and 1996
also reflect increases in average invested assets.
 
Partnership income increased to $6.7 million (a yield of 15.28% on related
average assets of $44.0 million) in 1997, compared with $4.1 million (a yield of
10.12% on related average assets of $40.2 million) in 1996 and $5.1 million (a
yield of 10.60% on related average assets of $48.4 million) in 1995. Partnership
income is based primarily upon cash distributions received from limited
partnerships, the operations of which the Company does not influence.
Consequently, such income is not predictable and there can be no assurance that
the Company will realize comparable levels of such income in the future.

Total interest expense equalled $137.6 million in 1997, $107.8 million in 1996
and $79.4 million in 1995. The average rate paid on all interest-bearing
liabilities was 5.46% in 1997, compared with 5.25% in 1996 and 4.99% in 1995.
Interest-bearing liabilities averaged $2.52 billion during 1997, compared with
$2.05 billion during 1996 and $1.59 billion during 1995.
 
The increases in the overall rates paid on interest-bearing liabilities during
1997 and 1996 primarily resulted from the impact of certain promotional one-year
interest rates offered on the fixed account portion of the Company's Polaris
variable annuity product. The increase in the overall rates paid on all
interest-bearing liabilities during 1996 was also impacted by the growth in
average reserves for GICs, which generally bear higher rates of interest than
fixed annuity contracts. Average GIC reserves were $340.5 million in 1996 and
$60.8 million in 1995. Most of the Company's GICs are variable rate and are
repriced quarterly at the then-current interest rates.
 
GROWTH IN AVERAGE INVESTED ASSETS since 1995 primarily reflects the sales of the
Company's fixed-rate products, consisting of both fixed annuity premiums
(including those for the fixed accounts of variable annuity products) and GIC
premiums. Fixed annuity premiums totaled $1.10 billion in 1997, compared with
$741.8 million in 1996 and $284.4 million in 1995. The premiums for the fixed
accounts of variable annuities have increased primarily because of increased
sales of the Company's Polaris product and greater inflows into the one-year
fixed account of that product. The Company has observed that many purchasers of
its variable annuity contracts allocate new premiums to the one-year fixed
account and concurrently elect the option to dollar cost average into one or
more variable funds. Accordingly, the Company anticipates that it will see a
large portion of these premiums transferred into the variable funds.
 
GIC premiums totaled $55.0 million in 1997, $135.0 million in 1996 and $275.0
million in 1995. GIC surrenders and maturities totaled $198.1 million in 1997,
$16.5 million in 1996 and $1.6 million in 1995. The Company does not actively
market GICs; consequently, premiums may vary substantially from period to
period. The large increase in surrenders and maturities in 1997 was primarily
due to contracts maturing in 1997. The GICs issued by the Company generally
guarantee the payment of principal and interest at fixed or variable rates for a
term of three to five years. Contracts that are purchased by banks for their
long-term portfolios, or state and local governmental entities either prohibit
withdrawals or permit scheduled book value withdrawals subject to the terms of
the underlying indenture or agreement. GICs purchased by asset management firms
for their short-term portfolios either prohibit withdrawals or permit
withdrawals with notice ranging from 90 to 270 days. In pricing GICs, the
Company analyzes cash flow information and prices accordingly so that it is
compensated for possible withdrawals prior to maturity.
 
NET REALIZED INVESTMENT LOSSES totaled $17.4 million in 1997, $13.4 million in
1996 and $4.4 million in 1995. Net realized investment losses include impairment
writedowns of $20.4 million in 1997, $16.0 million in 1996 and $4.8 million in
1995. Therefore, net gains from sales of investments totaled $3.0 million in
1997, $2.6 million in 1996 and $0.4 million in 1995.
 
The Company sold invested assets, principally bonds and notes, aggregating $2.19
billion, $1.28 billion and $1.15 billion in 1997, 1996 and 1995, respectively.
Sales of investments result from the active management of the Company's
investment portfolio. Because sales of investments are made in both rising and
falling interest rate environments, net gains from sales of investments
fluctuate from period to period, and represent 0.11%, 0.12% and 0.02% of average
invested assets for 1997, 1996 and 1995, respectively. Active portfolio
management involves the ongoing evaluation of asset sectors, individual
securities within the investment portfolio and the reallocation of investments
from sectors that are perceived to be relatively overvalued to sectors that are
perceived to be relatively undervalued. The intent of the Company's active
portfolio management is to maximize total returns on the investment portfolio,
taking into account credit and interest-rate risk.
 
Impairment writedowns reflect $15.7 million and $15.2 million of provisions
applied to non-income producing land owned in Arizona in 1997 and 1996,
respectively. The statutory carrying value of this land had been guaranteed by
the Company's ultimate Parent, SunAmerica Inc. ("SunAmerica"). SunAmerica made
capital contributions of $28.4 million and $27.4 million on December 31, 1996
and 1995, respectively, to the Company through the Company's direct parent in
exchange for the termination of its guaranty with respect to this land.
Accordingly, the Company reduced the carrying value of this land to estimated
fair value to reflect the full termination of the guaranty. Impairment
writedowns in 1995 include $3.8 million of additional provisions applied to
defaulted bonds. Impairment writedowns represent 0.77%, 0.73% and 0.28% of
average invested assets for 1997, 1996 and 1995, respectively. For the five
years ended September 30, 1997, impairment writedowns as a percentage of average
invested assets have ranged from 0.28% to 2.20% and have averaged 1.16%. Such
writedowns are based upon estimates of the net realizable value of the
applicable assets. Actual realization will be dependent upon future events.
 
VARIABLE ANNUITY FEES are based on the market value of assets in separate
accounts supporting variable annuity contracts. Such fees totaled $139.5 million
in 1997, $104.0 million in 1996 and $84.2 million in 1995. These increased fees
reflect growth in average variable annuity assets, principally due to the
receipt of variable annuity premiums, increased market
 
                                        3
<PAGE>   8
 
values and net exchanges into the separate accounts from the fixed accounts of
variable annuity contracts, partially offset by surrenders. Variable annuity
assets averaged $7.55 billion during 1997, $5.70 billion during 1996 and $4.65
billion during 1995. Variable annuity premiums, which exclude premiums allocated
to the fixed accounts of variable annuity products, totaled $1.27 billion in
1997, $919.8 million in 1996 and $577.2 million in 1995. Sales of variable
annuity products (which include premiums allocated to the fixed accounts)
("Variable Annuity Product Sales") amounted to $2.37 billion, $1.66 billion and
$861.0 million in 1997, 1996 and 1995, respectively. Increases in Variable
Annuity Product Sales are due, in part, to market share gains through enhanced
distribution efforts and growing consumer demand for flexible retirement savings
products that offer a variety of equity, fixed income and guaranteed fixed
account investment choices. The Company has encountered increased competition in
the variable annuity marketplace during recent years and anticipates that the
market will remain highly competitive for the foreseeable future. Also, from
time to time, Federal initiatives are proposed which could affect the taxation
of variable annuities and annuities generally (See "Regulation").
 
NET RETAINED COMMISSIONS are primarily derived from commissions on the sales of
nonproprietary investment products by the Company's broker-dealer subsidiary,
after deducting the substantial portion of such commissions that is passed on to
registered representatives. Net retained commissions totaled $39.1 million in
1997, $31.5 million in 1996 and $24.1 million in 1995. Broker-dealer sales
(mainly sales of general securities, mutual funds and annuities) totaled $11.56
billion in 1997, $8.75 billion in 1996 and $5.67 billion in 1995. The increases
in sales and net retained commissions reflect a greater number of registered
representatives, due to the Company's ongoing recruitment of representatives and
to the transfer of representatives from an affiliated broker-dealer, higher
average production per representative and generally favorable market conditions.
Increases in net retained commissions may not be proportionate to increases in
sales primarily due to differences in sales mix.
 
SURRENDER CHARGES on fixed and variable annuities totaled $5.5 million in 1997,
compared with $5.2 million in 1996 and $5.9 million in 1995. Surrender charges
generally are assessed on annuity withdrawals at declining rates during the
first seven years of an annuity contract. Withdrawal payments, which include
surrenders and lump-sum annuity benefits, totaled $1.06 billion in 1997,
compared with $898.0 million in 1996 and $908.9 million in 1995. These payments
represent 11.22%, 12.44% and 15.06%, respectively, of average fixed and variable
annuity reserves. Withdrawals include variable annuity withdrawals from the
separate accounts totaling $822.0 million in 1997, $634.1 million in 1996 and
$632.1 million in 1995. Management anticipates that withdrawal rates will remain
relatively stable for the foreseeable future.
 
ASSET MANAGEMENT FEES, which include investment advisory fees and 12b-1
distribution fees, are based on the market value of assets managed in mutual
funds by SunAmerica Asset Management Corp. Such fees totaled $25.8 million on
average assets managed of $2.34 billion in 1997, $25.4 million on average assets
managed of $2.14 billion in 1996 and $26.9 million on average assets managed of
$2.07 billion in 1995. Asset management fees are not proportionate to average
assets managed, principally due to changes in product mix. Sales of mutual
funds, excluding sales of money market accounts, amounted to $454.8 million in
1997, compared with $223.4 million in 1996 and $140.2 million in 1995.
Redemptions of mutual funds, excluding redemptions of money market accounts,
amounted to $412.8 million in 1997, $379.9 million in 1996 and $426.5 million in
1995. The significant increases in sales during 1997 principally resulted from
the introduction in November 1996 of the Company's "Style Select Series"
product. Higher mutual fund sales and lower redemptions in 1996 both reflect
enhanced marketing efforts and the favorable performance records of certain of
the Company's mutual funds, and heightened consumer demand for equity
investments generally.
 
GENERAL AND ADMINISTRATIVE EXPENSES totaled $98.8 million in 1997, compared with
$81.6 million in 1996 and $65.3 million in 1995. General and administrative
expenses in 1997 include a $6.2 million provision for estimated programming
costs associated with the year 2000. Management believes that this provision is
adequate and does not anticipate any material future expenses associated with
this project. General and administrative expenses remain closely controlled
through a company-wide cost containment program and continue to represent less
than 1% of average total assets.
 
AMORTIZATION OF DEFERRED ACQUISITION COSTS totaled $66.9 million in 1997,
compared with $57.5 million in 1996 and $58.7 million in 1995. The increase in
amortization during 1997 was primarily due to additional fixed and variable
annuity sales and the subsequent amortization of related deferred commissions
and other direct selling costs. The decline in amortization for 1996 is due to
lower redemptions of mutual funds from the rate experienced in 1995, partially
offset by additional fixed and variable annuity and mutual fund sales in recent
years and the subsequent amortization of related deferred commissions and other
acquisition costs.
 
ANNUAL COMMISSIONS represent renewal commissions paid quarterly in arrears to
maintain the persistency of certain of the Company's variable annuity contracts.
Substantially all of the Company's currently available variable annuity products
allow for an annual commission payment option in return for a lower immediate
commission. Annual commissions totaled $9.0 million in 1997, $4.6 million in
1996 and $2.7 million in 1995. The increase in annual commissions since 1995
reflects
                                        4
<PAGE>   9
 
increased sales of annuities that offer this commission option. The Company
estimates that approximately 45% of the average balances of its variable annuity
products is currently subject to such annual commissions. Based on current
sales, this percentage is expected to increase in future periods.
 
INCOME TAX EXPENSE totaled $31.2 million in 1997, compared with $24.3 million in
1996 and $25.7 million in 1995, representing effective tax rates of 33% in 1997,
35% in 1996 and 40% in 1995. The higher effective tax rate in 1995 was due to a
prior year tax settlement. Without such payment, the effective tax rate would
have been 33%.
 
FINANCIAL CONDITION AND LIQUIDITY AT SEPTEMBER 30, 1997
 
SHAREHOLDER'S EQUITY increased 18.5% to $575.2 million at September 30, 1997
from $485.3 million at September 30, 1996, primarily due to $63.1 million of net
income recorded in 1997 and $18.4 million of net unrealized gains on debt and
equity securities available for sale (credited directly to shareholder's
equity), versus $5.5 million of net unrealized losses on such securities
recorded at September 30, 1996. In addition, the Company received a contribution
of capital of $28.4 million in December 1996 and paid a dividend of $25.5
million in April 1997.
 
INVESTED ASSETS at year end totaled $2.61 billion in 1997, compared with $2.33
billion at year-end 1996. This 12.0% increase primarily resulted from sales of
fixed annuities and the $44.7 million net unrealized gain recorded on debt and
equity securities available for sale at September 30, 1997, versus the $12.7
million net unrealized loss recorded on such securities at September 30, 1996.
 
The Company manages most of its invested assets internally. The Company's
general investment philosophy is to hold
fixed-rate assets for long-term investment. Thus, it does not have a trading
portfolio. However, the Company has determined that all of its portfolio of
bonds, notes and redeemable preferred stocks (the "Bond Portfolio") is available
to be sold in response to changes in market interest rates, changes in relative
value of asset sectors and individual securities, changes in prepayment risk,
changes in the credit quality outlook for certain securities, the Company's need
for liquidity and other similar factors.
 
THE BOND PORTFOLIO, which comprises 76% of the Company's total investment
portfolio (at amortized cost), had an aggregate fair value that exceeded its
amortized cost by $43.7 million at September 30, 1997. At September 30, 1996,
the amortized cost exceeded the fair value of the Bond Portfolio by $13.8
million. The net unrealized gains on the Bond Portfolio since September 30, 1996
principally reflect the lower prevailing interest rates at September 30, 1997
and the corresponding effect on the fair value of the Bond Portfolio.
 
At September 30, 1997, the Bond Portfolio (at amortized cost, excluding $6.1
million of redeemable preferred stocks) included $1.82 billion of bonds rated by
Standard & Poor's Corporation ("S&P"), Moody's Investors Service ("Moody's"),
Duff & Phelps Credit Rating Co. ("DCR"), Fitch Investors Service, L.P. ("Fitch")
or the National Association of Insurance Commissioners ("NAIC"), and $124.4
million of bonds rated by the Company pursuant to statutory ratings guidelines
established by the NAIC. At September 30, 1997, approximately $1.72 billion of
the Bond Portfolio was investment grade, including $650.3 million of U.S.
government/agency securities and mortgage-backed securities ("MBSs").
 
At September 30, 1997, the Bond Portfolio included $216.9 million (at amortized
cost with a fair value of $227.2 million) of bonds that were not investment
grade. Based on their September 30, 1997 amortized cost, these
non-investment-grade bonds accounted for 1.7% of the Company's total assets and
8.5% of its invested assets.
 
Non-investment-grade securities generally provide higher yields and involve
greater risks than investment-grade securities because their issuers typically
are more highly leveraged and more vulnerable to adverse economic conditions
than investment-grade issuers. In addition, the trading market for these
securities is usually more limited than for investment-grade securities. The
Company had no material concentrations of non-investment-grade securities at
September 30, 1997. The following table summarizes the Company's rated bonds by
rating classification as of September 30, 1997.

- --------------------------------------------------------------------------------
(1) S&P and Fitch rate debt securities in rating categories ranging from AAA
    (the highest) to D (in payment default). A plus (+) or minus (-) indicates
    the debt's relative standing within the rating category. A security rated
    BBB- or higher is considered investment grade. Moody's rates debt securities
    in rating categories ranging from Aaa (the highest) to C (extremely poor
    prospects of ever attaining any real investment standing). The number 1, 2
    or 3 (with 1 the highest and 3 the lowest) indicates the debt's relative
    standing within the rating category. A security rated Baa3 or higher is
    considered investment grade. DCR rates debt securities in rating categories
    ranging from AAA (the highest) to DD (in payment default). A plus (+) or
    minus (-) indicates the debt's relative standing within the rating category.
    A security rated BBB- or higher is considered investment grade. Issues are
    categorized based on the highest of the S&P, Moody's, D&P and Fitch ratings
    if rated by multiple agencies.
 
(2) Bonds and short-term promissory instruments are divided into six quality
    categories for NAIC rating purposes, ranging from 1 (highest) to 5 (lowest)
    for nondefaulted bonds plus one category, 6, for bonds in or near default.
    These six categories correspond with the S&P/Moody's/DCR/Fitch rating groups
    listed above, with categories 1 and 2 considered investment grade. The NAIC
    categories include $124.4 million (at amortized cost) of assets that were
    rated by the Company pursuant to applicable NAIC rating guidelines.
 
(3) At amortized cost.
 
SENIOR SECURED LOANS ("Secured Loans") are included in the Bond Portfolio and
their amortized cost aggregated $329.3 million at September 30, 1997. Secured
Loans are senior to subordinated debt and equity, and are secured by assets of
the issuer. At September 30, 1997, Secured Loans consisted of loans to 80
borrowers spanning 28 industries, with 17% of these assets (at amortized cost)
concentrated in financial institutions. No other industry concentration
constituted more than 10% of these assets.
 
While the trading market for the Company's privately traded Secured Loans is
more limited than for publicly traded issues, management believes that
participation in these transactions has enabled the Company to improve its
investment yield. As a result of restrictive financial covenants, these Secured
Loans involve greater risk of technical default than do publicly traded
investment-grade securities. However, management believes that the risk of loss
upon default for these Secured Loans is
 
                                        6

mitigated by such financial covenants and the collateral values underlying the
Secured Loans. The Company's Secured Loans are rated by S&P, Moody's, DCR,
Fitch, the NAIC or by the Company, pursuant to comparable statutory ratings
guidelines established by the NAIC.
 
MORTGAGE LOANS aggregated $339.5 million at September 30, 1997 and consisted of
73 commercial first mortgage loans with an average loan balance of approximately
$4.7 million, collateralized by properties located in 21 states. Approximately
23% of this portfolio was multifamily residential, 18% was office, 14% was
manufactured housing, 13% was hotels, 11% was retail, 11% was industrial and 10%
was other types. At September 30, 1997, approximately 13% and 12% of this
portfolio was secured by properties located in New York and California,
respectively, and no more than 10% of this portfolio was secured by properties
located in any other single state. At September 30, 1997, there were four
mortgage loans with outstanding balances of $10 million or more, which loans
collectively aggregated approximately 17% of this portfolio. At the time of
their origination or purchase by the Company, virtually all mortgage loans had
loan-to-value ratios of 75% or less. At September 30, 1997, approximately 23% of
the mortgage loan portfolio consisted of loans with balloon payments due before
October 1, 2000. During 1997, 1996 and 1995, loans delinquent by more than 90
days, foreclosed loans and restructured loans have not been significant in
relation to the total mortgage loan portfolio.
 
At September 30, 1997, approximately 18% of the mortgage loans were seasoned
loans underwritten to the Company's standards and purchased at or near par from
other financial institutions. Such loans generally have higher average interest
rates than loans that could be originated today. The balance of the mortgage
loan portfolio has been originated by the Company under strict underwriting
standards. Commercial mortgage loans on properties such as offices, hotels and
shopping centers generally represent a higher level of risk than do mortgage
loans secured by multifamily residences. This greater risk is due to several
factors, including the larger size of such loans and the more immediate effects
of general economic conditions on these commercial property types. However, due
to its emphasis on multifamily loans and its strict underwriting standards, the
Company believes that it has prudently managed the risk attributable to its
mortgage loan portfolio while maintaining attractive yields.
 
OTHER INVESTED ASSETS aggregated $143.7 million at September 30, 1997, including
$46.9 million of investments in limited partnerships, $70.9 million of separate
account investments and an aggregate of $25.9 million of miscellaneous
investments, including policy loans, residuals and leveraged leases. The
Company's limited partnership interests, accounted for by using the cost method
of accounting, are invested primarily in a combination of debt and equity
securities.
 
ASSET-LIABILITY MATCHING is utilized by the Company to minimize the risks of
interest rate fluctuations and disintermediation. The Company believes that its
fixed-rate liabilities should be backed by a portfolio principally composed of
fixed-rate investments that generate predictable rates of return. The Company
does not have a specific target rate of return. Instead, its rates of return
vary over time depending on the current interest rate environment, the slope of
the yield curve, the spread at which fixed-rate investments are priced over the
yield curve, and general economic conditions. Its portfolio strategy is
constructed with a view to achieve adequate risk-adjusted returns consistent
with its investment objectives of effective asset-liability matching, liquidity
and safety. The Company's fixed-rate products incorporate surrender charges or
other restrictions in order to encourage persistency. Approximately 77% of the
Company's fixed annuity and GIC reserves had surrender penalties or other
restrictions at September 30, 1997.
 
As part of its asset-liability matching discipline, the Company conducts
detailed computer simulations that model its fixed-rate assets and liabilities
under commonly used stress-test interest rate scenarios. With the results of
these computer simulations, the Company can measure the potential gain or loss
in fair value of its interest-rate sensitive instruments and seek to protect its
economic value and achieve a predictable spread between what it earns on its
invested assets and what it pays on its liabilities by designing its fixed-rate
products and conducting its investment operations to closely match the duration
of the fixed-rate assets to that of its fixed-rate liabilities. The Company's
fixed-rate assets include: cash and short-term investments; bonds, notes and
redeemable preferred stocks; mortgage loans; and investments in limited
partnerships that invest primarily in fixed-rate securities and are accounted
for by using the cost method. At September 30, 1997, these assets had an
aggregate fair value of $2.48 billion with a duration of 3.4. The Company's
fixed-rate liabilities include fixed annuities and GICs. At September 30, 1997,
these liabilities had an aggregate fair value (determined by discounting future
contractual cash flows by related market rates of interest) of $2.32 billion
with a duration of 1.3. The Company's potential exposure due to a relative 10%
increase in interest rates prevalent at September 30, 1997 is a loss of
approximately $31.2 million in fair value of its fixed-rate assets that is not
offset by an increase in the fair value of its fixed-rate liabilities. Because
the Company actively manages its assets and liabilities and has strategies in
place to minimize its exposure to loss as interest rate changes occur, it
expects that actual losses would be less than the estimated potential loss.
 
                                        7

Duration is a common option-adjusted measure for the price sensitivity of a
fixed-maturity portfolio to changes in interest rates. It measures the
approximate percentage change in the market value of a portfolio if interest
rates change by 100 basis points, recognizing the changes in cash flows
resulting from embedded options such as policy surrenders, investment
prepayments and bond calls. It also incorporates the assumption that the Company
will continue to utilize its existing strategies of pricing its fixed annuity
and GIC products, allocating its available cash flow amongst its various
investment portfolio sectors and maintaining sufficient levels of liquidity.
Because the calculation of duration involves estimation and incorporates
assumptions, potential changes in portfolio value indicated by the portfolio's
duration will likely be different from the actual changes experienced under
given interest rate scenarios, and the differences may be material.
 
As a component of its asset and liability management strategy, the Company
utilizes interest rate swap agreements ("Swap Agreements") to match assets more
closely to liabilities. Swap Agreements are agreements to exchange with a
counterparty interest rate payments of differing character (for example,
variable-rate payments exchanged for fixed-rate payments) based on an underlying
principal balance (notional principal) to hedge against interest rate changes.
The Company typically utilizes Swap Agreements to create a hedge that
effectively converts floating-rate assets and liabilities into fixed-rate
instruments. At September 30, 1997, the Company had one outstanding Swap
Agreement with a notional principal amount of $15.9 million. This agreement
matures in December 2024.
 
The Company also seeks to provide liquidity from time to time by using reverse
repurchase agreements ("Reverse Repos") and by investing in MBSs. It also seeks
to enhance its spread income by using Reverse Repos. Reverse Repos involve a
sale of securities and an agreement to repurchase the same securities at a later
date at an agreed upon price and are generally
over-collateralized. MBSs are generally investment-grade securities
collateralized by large pools of mortgage loans. MBSs generally pay principal
and interest monthly. The amount of principal and interest payments may
fluctuate as a result of prepayments of the underlying mortgage loans.
 
There are risks associated with some of the techniques the Company uses to
provide liquidity, enhance its spread income and match its assets and
liabilities. The primary risk associated with the Company's Reverse Repos and
Swap Agreements is counterparty risk. The Company believes, however, that the
counterparties to its Reverse Repos and Swap Agreements are financially
responsible and that the counterparty risk associated with those transactions is
minimal. It is the Company's policy that these agreements are entered into with
counterparties who have a debt rating of A/A2 or better from both S&P and
Moody's. The Company continually monitors its credit exposure with respect to
these agreements. In addition to counterparty risk, Swap Agreements also have
interest rate risk. However, the Company's Swap Agreements typically hedge
variable-rate assets or liabilities, and interest rate fluctuations that
adversely affect the net cash received or paid under the terms of a Swap
Agreement would be offset by increased interest income earned on the
variable-rate assets or reduced interest expense paid on the variable-rate
liabilities. The primary risk associated with MBSs is that a changing interest
rate environment might cause prepayment of the underlying obligations at speeds
slower or faster than anticipated at the time of their purchase. As part of its
decision to purchase an MBS, the Company assesses the risk of prepayment by
analyzing the security's projected performance over an array of interest-rate
scenarios. Once an MBS is purchased, the Company monitors its actual prepayment
experience monthly to reassess the relative attractiveness of the security with
the intent to maximize total return.
 
INVESTED ASSETS EVALUATION is routinely conducted by the Company. Management
identifies monthly those investments that require additional monitoring and
carefully reviews the carrying values of such investments at least quarterly to
determine whether specific investments should be placed on a nonaccrual basis
and to determine declines in value that may be other than temporary. In making
these reviews for bonds, management principally considers the adequacy of any
collateral, compliance with contractual covenants, the borrower's recent
financial performance, news reports and other externally generated information
concerning the creditor's affairs. In the case of publicly traded bonds,
management also considers market value quotations, if available. For mortgage
loans, management generally considers information concerning the mortgaged
property and, among other things, factors impacting the current and expected
payment status of the loan and, if available, the current fair value of the
underlying collateral. For investments in partnerships, management reviews the
financial statements and other information provided by the general partners.
 
The carrying values of investments that are determined to have declines in value
that are other than temporary are reduced to net realizable value and, in the
case of bonds, no further accruals of interest are made. The provisions for
impairment on mortgage loans are based on losses expected by management to be
realized on transfers of mortgage loans to real estate, on the disposition and
settlement of mortgage loans and on mortgage loans that management believes may
not be collectible in full. Accrual of interest is suspended when principal and
interest payments on mortgage loans are past due more than 90 days.

DEFAULTED INVESTMENTS, comprising all investments that are in default as to the
payment of principal or interest, totaled $1.4 million at September 30, 1997 (at
amortized cost after impairment writedowns, with a fair value of $1.4 million),
including $0.5 million of bonds and notes and $0.9 million of mortgage loans. At
September 30, 1997, defaulted investments constituted 0.1% of total invested
assets. At September 30, 1996, defaulted investments totaled $3.1 million,
including $1.6 million of bonds and notes and $1.5 million of mortgage loans,
and constituted 0.1% of total invested assets.
 
SOURCES OF LIQUIDITY are readily available to the Company in the form of the
Company's existing portfolio of cash and short-term investments, Reverse Repo
capacity on invested assets and, if required, proceeds from invested asset
sales. At September 30, 1997, approximately $1.80 billion of the Company's Bond
Portfolio had an aggregate unrealized gain of $46.5 million, while approximately
$139.8 million of the Bond Portfolio had an aggregate unrealized loss of $2.7
million. In addition, the Company's investment portfolio currently provides
approximately $22.5 million of monthly cash flow from scheduled principal and
interest payments. Historically, cash flows from operations and from the sale of
the Company's annuity and GIC products have been more than sufficient in amount
to satisfy the Company's liquidity needs.
 
Management is aware that prevailing market interest rates may shift
significantly and has strategies in place to manage either an increase or
decrease in prevailing rates. In a rising interest rate environment, the
Company's average cost of funds would increase over time as it prices its new
and renewing annuities and GICs to maintain a generally competitive market rate.
Management would seek to place new funds in investments that were matched in
duration to, and higher yielding than, the liabilities assumed. The Company
believes that liquidity to fund withdrawals would be available through incoming
cash flow, the sale of short-term or floating-rate instruments or Reverse Repos
on the Company's substantial MBS segment of the Bond Portfolio, thereby avoiding
the sale of fixed-rate assets in an unfavorable bond market.
 
In a declining rate environment, the Company's cost of funds would decrease over
time, reflecting lower interest crediting rates on its fixed annuities and GICs.
Should increased liquidity be required for withdrawals,the Company believes that
a significant portion of its investments could be sold without adverse
consequences in light of the general strengthening that would be expected in the
bond market.
 
The Company relies significantly on computer systems and applications in its
daily operations. Many of these systems and applications are not presently year
2000 compliant. The Company's business, financial condition and results of
operations could be materially and adversely affected by the failure of the
Company's systems and applications (and those operated by third parties
interfacing with the Company's systems and applications) to properly operate or
manage dates beyond the year 1999. The Company has a coordinated plan to repair
or replace these noncompliant systems and to obtain similar assurances from
third parties interfacing with the Company's systems and applications. In Fiscal
year 1997, the Company recorded a $6.2 million provision for estimated
programming costs to make necessary repairs of certain specific noncompliant
systems. Management also expects to make expenditures totaling $5.0 million to
replace certain other specific noncompliant systems, which expenditures will be
capitalized as software costs and amortized over future periods. Both phases of
the project are currently proceeding in accordance with the plan and management
expects them to be substantially completed by the end of 1998. Testing of both
the repaired and replacement systems will be conducted during calendar 1999.
 
RESULTS OF OPERATIONS FOR THE FIRST NINE MONTHS OF 1998
 
NET INCOME totaled $100.3 million for the first nine months of 1998, compared
with $34.7 million for the first nine months of 1997.
 
PRETAX INCOME totaled $155.1 million in the first nine months of 1998, compared
with $52.7 million in the first nine months of 1997. The significant improvement
in the current period over the prior period primarily resulted from increased
fee income and net realized investment gains.
 
NET INVESTMENT INCOME increased to $62.8 million in the first nine months of
1998 from $50.4 million in the first nine months of 1997. These amounts equal
3.29% on average invested assets (computed on a daily basis) of $2.55 billion in
the first nine months of 1998 and 2.52% on average invested assets of $2.66
billion in the first nine months of 1997.
 
The excess of average invested assets over average interest-bearing liabilities
amounted to $109.1 million in the first nine months of 1998 and $131.2 million
in the first nine months of 1997. The Spread Difference was 3.06% in the first
nine months of 1998 and 2.25% in the first nine months of 1997.
 
Investment income (and the related yields on average invested assets) totaled
$162.2 million (8.49%) in the first nine months of 1998 and $153.7 million
(7.70%) in the first nine months of 1997. Investment income and the related
yield in the first nine months of 1998 primarily reflect the higher returns
realized in the first quarter of 1998 on the Company's investments in limited
partnerships.
 
                                        9
<PAGE>   14
 
Partnership income amounted to $21.4 million (a yield of 197.19% on related
average assets of $14.5 million) in the first nine months of 1998, compared with
$5.0 million (a yield of 15.32% on related average assets of $43.4 million) in
the first nine months of 1997. Partnership income is based primarily upon cash
distributions received from limited partnerships, the operations of which the
Company does not influence. Consequently, such income is not predictable and
there can be no assurance that the Company will realize comparable levels of
such income in the future.
 
Total interest expense equalled $99.4 million in the first nine months of 1998,
compared with $103.3 million in the first nine months of 1997. The average rate
paid on all interest-bearing liabilities was 5.43% in the first nine months of
1998 and 5.45% in the first nine months of 1997. Interest-bearing liabilities
averaged $2.44 billion during the first nine months of 1998 and $2.53 billion
during the first nine months of 1997.
 
The modest decline in average invested assets in the first nine months of 1998,
which results from the net effect of increased sales of the Company's fixed rate
products and net exchanges from fixed accounts into the separate accounts of
variable annuity contracts, reflects a similar modest decline in average
interest-bearing liabilities. Fixed annuity premiums (comprised primarily of
premiums for the fixed accounts of variable annuities) totaled $1.05 billion in
the first nine months of 1998 and $877.9 million in the first nine months of
1997. On an annualized basis, these amounts represent 67% and 65% of fixed
annuity reserves at the beginning of the respective periods. A substantial
proportion of the fixed premiums received on Polaris annuity contracts were
allocated to the one-year fixed fund under an option to dollar cost average into
the variable funds. Accordingly, a large portion of these premiums have
transferred into the separate accounts, resulting in the modest decline in
average interest-bearing liabilities.
 
GIC premiums totaled $5.6 million in the first nine months of 1998 and $55.0
million in the first nine months of 1997. On an annualized basis, for the first
nine months of 1998 and 1997, these amounts represent 3% and 18% of GIC reserves
at the beginning of the respective periods.
 
NET REALIZED INVESTMENT GAINS totaled $25.9 million in the first nine months of
1998, compared with $22.7 million of net losses realized in the first nine
months of 1997, and include impairment writedowns of $2.2 million and $20.0
million, respectively. Thus, net gains from sales and redemptions of investments
totaled $28.1 million in the first nine months of 1998, compared with net losses
of $2.7 million in the first nine months of 1997.
 
The Company sold or redeemed invested assets, principally bonds and notes,
aggregating $1.58 billion in the first nine months of 1998 and $2.19 billion in
the first nine months of 1997. Sales of investments result from the active
management of the Company's investment portfolio. Because redemptions of
investments are generally involuntary and sales of investments are made in both
rising and falling interest rate environments, net gains and losses from sales
and redemptions of investments fluctuate from period to period, and represent
1.47% and 0.14% of average invested assets on an annualized basis for the first
nine months of 1998 and the first nine months of 1997, respectively.
 
Impairment writedowns in the first nine months of 1997 reflect 15.7 million of
provisions applied to non-income producing land owned in Arizona. Impairment
writedowns, on an annualized basis, represent 0.11% and 1.00% of average
invested assets for the first nine months of 1998 and the first nine months of
1997, respectively. For the 19 fiscal quarters beginning October 1, 1993,
impairment writedowns as a percentage of average invested assets have ranged up
to 3.64% and have averaged 0.80%.
 
VARIABLE ANNUITY FEES totaled $145.5 million in the first nine months of 1998,
compared with $98.2 million in the first nine months of 1997. These increased
fees reflect growth in average variable annuity assets, due to increased market
values, the receipt of variable annuity premiums and net exchanges into the
separate accounts from the fixed accounts of variable annuity contracts,
partially offset by surrenders. On an annualized basis, variable annuity fees
represent 2% of average variable annuity assets for the first nine months of
1998 and 1997. Variable annuity assets averaged $10.38 billion in the first nine
moths of 1998, compared with $7.11 billion in the first nine months of 1997.
 
Variable annuity premiums, which exclude premiums allocated to the fixed
accounts of variable annuity products, have aggregated $1.76 billion since June
30, 1997. Variable annuity premiums increased to $1.35 billion in the first nine
months of 1998, compared with $859.6 million in the first nine months of 1997.
On an annualized basis, these amounts represent 19% and 18% of variable annuity
reserves at the beginning of the respective periods.
 
Variable Annuity Product Sales amounted to $2.40 billion and $1.74 billion in
the first nine months of 1998 and 1997, respectively, and primarily reflect
sales of the Company's flagship variable annuity, Polaris. Polaris is a
multi-manager variable annuity that offers investors a choice of 26 variable
funds and 7 guaranteed fixed-rate funds. Increases in Variable Annuity Product
Sales are due, in part, to market share gains through enhanced distribution
efforts and growing consumer
 
                                       10

demand for flexible retirement savings products that offer a variety of equity,
fixed income and guaranteed fixed account investment choices.
 
NET RETAINED COMMISSIONS totaled $35.8 million in the first nine months of 1998
and $27.9 million in the first nine months of 1997. Broker-dealer sales totaled
$11.19 billion in the first nine months of 1998 and $7.69 billion in the first
nine months of 1997. The increases in sales and net retained commissions reflect
a greater number of registered representatives, higher average production per
representative and generally favorable market conditions.
 
SURRENDER CHARGES on fixed and variable annuities totaled $5.3 million in the
first nine months of 1998, compared with $3.8 million in the first nine months
of 1997. Withdrawal payments totaled $878.4 million in the first nine months of
1998 and $778.2 million in the first nine months of 1997 and, annualized,
represent 9.5% and 11.5%, respectively, of average fixed and variable annuity
reserves. Withdrawals include variable annuity withdrawals from the separate
accounts totaling $726.4 million (9.4% of average variable annuity reserves) and
$589.3 million (11.1% of average variable annuity reserves) in the first nine
months of 1998 and 1997, respectively. Approximately 77% of the Company's fixed
annuity and GIC reserves had surrender penalties or other restrictions at June
30, 1998. Management anticipates that withdrawal rates will remain relatively
stable for the foreseeable future.
 
ASSET MANAGEMENT FEES totaled $21.8 million on average assets managed of $2.83
billion in the first nine months of 1998, compared with $18.9 million on average
assets managed of $2.27 billion in the first nine months of 1997. Sales of
mutual funds, excluding sales of money market accounts, have aggregated $759.4
million since June 30, 1997. Mutual fund sales totaled $601.3 million in the
first nine months of 1998, more than double the $296.7 million in the first nine
months of 1997. The significant increases in sales during the first nine months
of 1998 principally resulted from the sales of the Company's "Style Select
Series" product, and the introduction in June 1998 of the "Dogs" of Wall Street
fund and the Style Select Focus Fund. The "Style Select Series" is a group of
mutual funds which are each managed by three industry recognized fund managers.
The "Dogs" of Wall Street fund contains 30 large capitalization value stocks
which are selected by strict criteria. The Style Select Focus Fund also limits
itself to 30 large capitalization stocks but primarily holds growth stocks.
Sales of these products totaled $425.8 million and $161.1 million for the first
nine months of 1998 and 1997, respectively, reflecting the addition of five new
Style Select funds, which more than doubled the number of Style Select funds to
nine, and generally favorable market conditions. Redemptions of mutual funds,
excluding redemptions of money market accounts, amounted to $313.3 million in
the first nine months of 1998 and $316.3 million in the first nine months of
1997.
 
GENERAL AND ADMINISTRATIVE EXPENSES totaled $71.6 million in the first nine
months of 1998 and $71.7 million in the first nine months of 1997. General and
administrative expenses remain closely controlled through a company-wide cost
containment program and continue to represent less than 1% of average total
assets.
 
AMORTIZATION OF DEFERRED ACQUISITION COSTS totaled $60.5 million in the first
nine months of 1998, compared with $48.8 million in the first nine months of
1997. The increase in amortization was primarily due to additional fixed and
variable annuity and mutual fund sales and the subsequent amortization of
related deferred commissions and other direct selling costs.
 
ANNUAL COMMISSIONS totaled $12.7 million in the first nine months of 1998 and
$5.9 million in the first nine months of 1997. The increase in annual
commissions reflects increased sales of annuities that offer this commission
option. The Company estimates that approximately 50% of the average balances of
its variable annuity products is currently subject to such annual commissions.
Based on current sales, this percentage is expected to increase in future
periods.
 
INCOME TAX EXPENSE totaled $54.8 million in the first nine months of 1998,
compared with $18.0 million in the first nine months of 1997, representing
effective tax rates of 35% and 34%, respectively.
 
FINANCIAL CONDITION AND LIQUIDITY AT JUNE 30, 1998
 
SHAREHOLDER'S EQUITY increased 42.7% to $820.9 million at June 30, 1998 from
$575.2 million at September 30, 1997, primarily due to the $200.4 million
capital contribution received by the Company in June 1998 and the $100.3 million
of net income recorded in the six months of 1998, partially offset by the $51.2
million dividend paid in June 1998. The $200.4 million capital contribution was
withdrawn during August 1998.
 
INVESTED ASSETS at June 30, 1998 totaled $2.77 billion, compared with $2.61
billion at September 30, 1997.
 
THE BOND PORTFOLIO, which constitutes 77% of the Company's total investment
portfolio (at amortized cost), had an aggregate fair value that exceeded its
amortized cost by $35.3 million at June 30, 1998, compared with an excess of
$43.7 million at September 30, 1997.
 
                                       11
<PAGE>   16
 
At June 30, 1998, the Bond Portfolio (at amortized cost, excluding $6.1 million
of redeemable preferred stocks) included $2.01 billion of bonds rated by S&P,
Moody's, DCR, Fitch or the NAIC and $100.1 million of bonds rated by the Company
pursuant to statutory ratings guidelines established by the NAIC. At June 30,
1998, approximately $1.90 billion of the Bond Portfolio was investment grade,
including $792.1 million of U.S. government/agency securities and MBSs.
 
At June 30, 1998, the Bond Portfolio included $202.0 million (at amortized cost
with a fair value of $202.0 million) of bonds that were not investment grade.
Based on their June 30, 1998 amortized cost, these non-investment-grade bonds
accounted for 1.3% of the Company's total assets and 7.4% of its invested
assets. The Company had no material concentrations of non-investment-grade
securities at June 30, 1998.
 
Senior secured loans are included in the Bond Portfolio and their amortized cost
aggregated $178.3 million at June 30, 1998. At June 30, 1998, Secured Loans
consisted of $83.7 million of publicly traded securities and $94.6 million of
privately traded securities. These Secured Loans are composed of loans to 63
borrowers spanning 20 industries, with 36% of these assets (at amortized cost)
concentrated in financial institutions. No other industry concentration
constituted more than 10% of these assets.
 
MORTGAGE LOANS aggregated $377.0 million at June 30, 1998 and consisted of 134
commercial first mortgage loans with an average loan balance of approximately
$2.8 million, collateralized by properties located in 28 states. Approximately
20% of this portfolio was office, 19% was multifamily residential, 15% was
hotel, 13% was manufactured housing, 10% was industrial and 23% was other types.
At June 30, 1998, approximately 17% and 16% of this portfolio were secured by
properties located in California and New York, respectively, and no more than 8%
of this portfolio was secured by properties located in any other single state.
At June 30, 1998, there were three mortgage loans with outstanding balances of
$10 million or more, which loans collectively aggregated approximately 11% of
this portfolio. At June 30, 1998, approximately 28% of the mortgage loan
portfolio consisted of loans with balloon payments due before July 1, 2001.
During the first nine months of 1998 and 1997, loans delinquent by more than 90
days, foreclosed loans and restructured loans have not been significant in
relation to the total mortgage loan portfolio.
 
At June 30, 1998, approximately 11% of the mortgage loans were seasoned loans
underwritten to the Company's standards and purchased at or near par from other
financial institutions.
 
OTHER INVESTED ASSETS aggregated $38.5 million at June 30, 1998, including $12.3
million of investments in limited partnerships and an aggregate of $26.2 million
of miscellaneous investments, including policy loans, residuals and leveraged
leases. The Company's limited partnership interests, accounted for by using the
cost method of accounting, are invested primarily in a combination of debt and
equity securities.
 
At June 30, 1998, the Company's fixed-rate assets had an aggregate fair value of
$2.66 billion with a duration of 3.9. At June 30, 1998, the Company's fixed-rate
liabilities had an aggregate fair value (determined by discounting future
contractual cash flows by related market rates of interest) of $2.41 billion
with a duration of 1.1. The Company's potential exposure due to a 10% increase
in prevailing interest rates from their June 30, 1998 levels is a loss of $41.8
million in fair value of its fixed-rate assets that is not offset by a decrease
in the fair value of its fixed-rate liabilities. Because the Company actively
manages its assets and liabilities and has strategies in place to minimize its
exposure to loss as interest rate changes occur, it expects that actual losses
would be less than the estimated potential loss.
 
At June 30, 1998, the Company had one outstanding Swap Agreement with a notional
principal amount of $21.5 million. This agreement matures in December 2024.
 
DEFAULTED INVESTMENTS, comprising all investments that are in default as to the
payment of principal or interest, totaled $2.4 million at June 30, 1998 (at
amortized cost, with a fair value of $2.4 million), including $1.5 million of
bonds and notes and $0.9 million of mortgage loans. At June 30, 1998, defaulted
investments constituted 0.1% of total invested assets. At September 30, 1997,
defaulted investments totaled $1.4 million, including $0.5 million of bonds and
notes and $0.9 million of mortgage loans, and constituted 0.1% of total invested
assets.
 
SOURCES OF LIQUIDITY are readily available to the Company in the form of the
Company's existing portfolio of cash and short-term investments, Reverse Repo
capacity on invested assets and, if required, proceeds from invested asset
sales. At June 30, 1998, approximately $1.67 billion of the Company's Bond
Portfolio had an aggregate unrealized gain of $44.6 million, while approximately
$446.0 million of the Bond Portfolio had an aggregate unrealized loss of $9.3
million. In addition, the Company's investment portfolio currently provides
approximately $24.1 million of monthly cash flow from scheduled principal and
interest payments.

REGULATION
 
The Company is subject to regulation and supervision by the insurance regulatory
agencies of the states in which it is authorized to transact business. State
insurance laws establish supervisory agencies with broad administrative and
supervisory powers. Principal among these powers are granting and revoking
licenses to transact business, regulating marketing and other trade practices,
operating guaranty associations, licensing agents, approving policy forms,
regulating certain premium rates, regulating insurance holding company systems,
establishing reserve and valuation requirements, prescribing the form and
content of required financial statements and reports, performing financial,
market conduct and other examinations, determining the reasonableness and
adequacy of statutory capital and surplus, defining acceptable accounting
principles, regulating the type, valuation and amount of investments permitted,
and limiting the amount of dividends that can be paid and the size of
transactions that can be consummated without first obtaining regulatory
approval.
 
During the last decade, the insurance regulatory framework has been placed under
increased scrutiny by various states, the federal government and the National
Association of Insurance Commissioners ("NAIC"). Various states have considered
or enacted legislation that changes, and in many cases increases, the states'
authority to regulate insurance companies. Legislation has been introduced from
time to time in Congress that could result in the federal government assuming
some role in the regulation of insurance companies or allowing combinations
between insurance companies, banks and other entities. In recent years, the NAIC
has developed several model laws and regulations designed to reduce the risk of
insurance company insolvencies and market conduct violations. These initiatives
include investment reserve requirements, risk-based capital ("RBC") standards,
codification of insurance accounting principles, new investment standards and
restrictions on an insurance company's ability to pay dividends to its
stockholders. The NAIC is also currently developing model laws or regulations
relating to product design, product reserving standards and illustrations of
annuity products. Current proposals are still being debated and the Company is
monitoring developments in this area and the effects any changes would have on
the Company.
 
The RBC standards consist of formulas which establish capital requirements
relating to insurance, business, assets and interest rate risks, and which help
to identify companies which are under-capitalized and require specific
regulatory actions in the event an insurer's RBC falls below specified levels.
The Company has more than enough statutory capital to meet the NAIC's RBC
requirements as of the most recent calendar year-end. Arizona, the Company's
domicile state, has adopted these RBC standards, and the Company is in
compliance with such laws. Further, for statutory reporting purposes, the
annuity reserves of the Company are calculated in accordance with statutory
requirements and are adequate under current cash-flow testing models.
 
SunAmerica Asset Management Corp., a subsidiary of the Company, is registered
with the SEC as an investment adviser under the Investment Advisers Act of 1940.
The mutual funds that it markets are subject to regulation under the Investment
Company Act of 1940. SunAmerica Asset Management Corp. and the mutual funds are
subject to regulation and examination by the SEC. In addition, variable
annuities and the related separate accounts of the Company are subject to
regulation by the SEC under the Securities Act of 1933 and the Investment
Company Act of 1940.
 
The Company's broker-dealer subsidiary, Royal Alliance Associates, Inc., is
subject to regulation and supervision by the states in which it transacts
business, as well as by the SEC and the National Association of Securities
Dealers ("NASD"). The SEC and the NASD have broad administrative and supervisory
powers relative to all aspects of business and may examine the subsidiary's
business and accounts at any time.
 
From time to time, Federal initiatives are proposed that could affect the
Company's businesses. Such initiatives include employee benefit plan regulations
and tax law changes affecting the taxation of insurance companies and the tax
treatment of insurance and other investment products. Proposals made in recent
years to limit the tax deferral of annuities or otherwise modify the tax rules
related to the treatment of annuities have not been enacted. While certain of
such proposals, if implemented, could have an adverse effect on the Company's
sales of affected products, and consequently on its results of operations, the
Company believes such proposals have a small likelihood of being enacted,
because they would discourage retirement savings and there is strong public and
industry opposition to them.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholder of
Anchor National Life Insurance Company
 
In our opinion, the accompanying consolidated balance sheet and the related
consolidated income statement and statement of cash flows present fairly, in all
material respects, the financial position of Anchor National Life Insurance
Company and its subsidiaries at September 30, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the period
ended September 30, 1997, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

1. NATURE OF OPERATIONS
 
Anchor National Life Insurance Company (the "Company") is a wholly owned
indirect subsidiary of SunAmerica, Inc. (the "Parent"). The Company is an
Arizona-domiciled life insurance company and conducts its business through three
segments: annuity operations, asset management and broker-dealer operations.
Annuity operations include the sale and administration of fixed and variable
annuities and guaranteed investment contracts. Asset management, which includes
the sale and management of mutual funds, is conducted by SunAmerica Asset
Management Corp. Broker-dealer operations include the sale of securities and
financial services products, and are conducted by Royal Alliance Associates,
Inc.
 
The operations of the Company are influenced by many factors, including general
economic conditions, monetary and fiscal policies of the federal government, and
policies of state and other regulatory authorities. The level of sales of the
Company's financial products is influenced by many factors, including general
market rates of interest; strength, weakness and volatility of equity markets;
and terms and conditions of competing financial products. The Company is exposed
to the typical risks normally associated with a portfolio of fixed-income
securities, namely interest rate, option, liquidity and credit risk. The Company
controls its exposure to these risks by, among other things, closely monitoring
and matching the duration of its assets and liabilities, monitoring and limiting
prepayment and extension risk in its portfolio, maintaining a large percentage
of its portfolio in highly liquid securities, and engaging in a disciplined
process of underwriting, reviewing and monitoring credit risk. The Company also
is exposed to market risk, as market volatility may result in reduced fee income
in the case of assets managed in mutual funds and held in separate accounts.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION: The accompanying consolidated financial statements have
been prepared in accordance with generally accepted accounting principles and
include the accounts of the Company and all of its wholly owned subsidiaries.
All significant intercompany accounts and transactions are eliminated in
consolidation. Certain prior period amounts have been reclassified to conform
with the 1997 presentation.
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires the use of estimates and assumptions that affect
the amounts reported in the financial statements and the accompanying notes.
Actual results could differ from those estimates.
 
INVESTMENTS: Cash and short-term investments primarily include cash, commercial
paper, money market investments, repurchase agreements and short-term bank
participations. All such investments are carried at cost plus accrued interest,
which approximates fair value, have maturities of three months or less and are
considered cash equivalents for purposes of reporting cash flows.
 
Bonds, notes and redeemable preferred stocks available for sale and common
stocks are carried at aggregate fair value and changes in unrealized gains or
losses, net of tax, are credited or charged directly to shareholder's equity.
Bonds, notes and redeemable preferred stocks are reduced to estimated net
realizable value when necessary for declines in value considered to be other
than temporary. Estimates of net realizable value are subjective and actual
realization will be dependent upon future events.
 
Mortgage loans are carried at amortized unpaid balances, net of provisions for
estimated losses. Real estate is carried at the lower of cost or fair value.
Other invested assets include investments in limited partnerships, which are
accounted for by using the cost method of accounting; separate account
investments; leveraged leases; policy loans, which are carried at unpaid
balances; and collateralized mortgage obligation residuals.
 
Realized gains and losses on the sale of investments are recognized in
operations at the date of sale and are determined using the specific cost
identification method. Premiums and discounts on investments are amortized to
investment income using the interest method over the contractual lives of the
investments.
 
INTEREST RATE SWAP AGREEMENTS: The net differential to be paid or received on
interest rate swap agreements ("Swap Agreements") entered into to reduce the
impact of changes in interest rates is recognized over the lives of the
agreements, and such differential is classified as Interest Expense in the
income statement. All outstanding Swap Agreements are designated as hedges and,
therefore, are not marked to market. However, in the event that a hedged
asset/liability were to be sold or repaid before the related Swap Agreement
matures, the Swap Agreement would be marked to market and any

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
gain/loss classified with any gain/loss realized on the disposition of the
hedged asset/liability. Subsequently, the Swap Agreement would be marked to
market and the resulting change in fair value would be included in Investment
Income in the income statement. In the event that a Swap Agreement that is
designated as a hedge were to be terminated before its contractual maturity, any
resulting gain/loss would be credited/charged to the carrying value of the
asset/liability that it hedged.
 
DEFERRED ACQUISITION COSTS: Policy acquisition costs are deferred and amortized,
with interest, in relation to the incidence of estimated gross profits to be
realized over the estimated lives of the annuity contracts. Estimated gross
profits are composed of net interest income, net realized investment gains and
losses, variable annuity fees, surrender charges and direct administrative
expenses. Costs incurred to sell mutual funds are also deferred and amortized
over the estimated lives of the funds obtained. Deferred acquisition costs
consist of commissions and other costs that vary with, and are primarily related
to, the production or acquisition of new business.
 
As debt and equity securities available for sale are carried at aggregate fair
value, an adjustment is made to deferred acquisition costs equal to the change
in amortization that would have been recorded if such securities had been sold
at their stated aggregate fair value and the proceeds reinvested at current
yields. The change in this adjustment, net of tax, is included with the change
in net unrealized gains or losses on debt and equity securities available for
sale that is credited or charged directly to shareholder's equity. Deferred
Acquisition Costs have been decreased by $16,400,000 at September 30, 1997 and
increased by $4,200,000 at September 30, 1996 for this adjustment.
 
VARIABLE ANNUITY ASSETS AND LIABILITIES: The assets and liabilities resulting
from the receipt of variable annuity premiums are segregated in separate
accounts. The Company receives administrative fees for managing the funds and
other fees for assuming mortality and certain expense risks. Such fees are
included in Variable Annuity Fees in the income statement.
 
GOODWILL: Goodwill, amounting to $18,311,000 at September 30, 1997, is amortized
by using the straight-line method over periods averaging 25 years and is
included in Other Assets in the balance sheet. Goodwill is evaluated for
impairment when events or changes in economic conditions indicate that the
carrying amount may not be recoverable.
 
CONTRACTHOLDER RESERVES: Contractholder reserves for fixed annuity contracts and
guaranteed investment contracts are accounted for as investment-type contracts
in accordance with Statement of Financial Accounting Standards No. 97,
"Accounting and Reporting by Insurance Enterprises for Certain Long-Duration
Contracts and for Realized Gains and Losses from the Sale of Investments," and
are recorded at accumulated value (premiums received, plus accrued interest,
less withdrawals and assessed fees).
 
FEE INCOME: Variable annuity fees, asset management fees and surrender charges
are recorded in income as earned. Net retained commissions are recognized as
income on a trade-date basis.
 
INCOME TAXES: The Company is included in the consolidated federal income tax
return of the Parent and files as a "life insurance company" under the
provisions of the Internal Revenue Code of 1986. Income taxes have been
calculated as if the Company filed a separate return. Deferred income tax assets
and liabilities are recognized based on the difference between financial
statement carrying amounts and income tax bases of assets and liabilities using
enacted income tax rates and laws.

Expenses incurred to manage the investment portfolio amounted to $2,050,000 for
the year ended September 30, 1997, $1,737,000 for the year ended September 30,
1996, and $1,983,000 for the year ended September 30, 1995 and are included in
General and Administrative Expenses in the income statement.
 
At September 30, 1997, no investment exceeded 10% of the Company's consolidated
shareholder's equity.
 
At September 30, 1997, mortgage loans were collateralized by properties located
in 21 states, with loans totaling approximately 13% of the aggregate carrying
value of the portfolio secured by properties located in New York and
approximately 12% by properties located in California. No more than 10% of the
portfolio was secured by properties in any other single state.
 
At September 30, 1997, bonds, notes and redeemable preferred stocks included
$216,877,000 (fair value of $227,169,000) of bonds and notes not rated
investment grade. The Company had no material concentrations of
non-investment-grade assets at September 30, 1997.
 
At September 30, 1997, the amortized cost of investments in default as to the
payment of principal or interest was $1,378,000, consisting of $500,000 of
non-investment-grade bonds and $878,000 of mortgage loans. Such nonperforming
investments had an estimated fair value of $1,378,000.
 
As a component of its asset and liability management strategy, the Company
utilizes Swap Agreements to match assets more closely to liabilities. Swap
Agreements are agreements to exchange with a counterparty interest rate payments
of differing character (for example, variable-rate payments exchanged for
fixed-rate payments) based on an underlying principal balance (notional
principal) to hedge against interest rate changes. The Company typically
utilizes Swap Agreements to create a hedge that effectively converts
floating-rate assets and liabilities to fixed-rate instruments. At September 30,
1997, the Company had one outstanding Swap Agreement with a notional principal
amount of $15.9 million, which matures in December, 2024. The net interest paid
amounted to $0.1 million for the year ended September 30, 1997, and is included
in Interest Expense on Guaranteed Investment Contracts in the income statement.
 
At September 30, 1997, $5,276,000 of bonds, at amortized cost, were on deposit
with regulatory authorities in accordance with statutory requirements.
 
4. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
The following estimated fair value disclosures are limited to reasonable
estimates of the fair value of only the Company's financial instruments. The
disclosures do not address the value of the Company's recognized and
unrecognized nonfinancial assets (including its real estate investments and
other invested assets except for cost-method partnerships) and liabilities or
the value of anticipated future business. The Company does not plan to sell most
of its assets or settle most of its liabilities at these estimated fair values.
 
The fair value of a financial instrument is the amount at which the instrument
could be exchanged in a current transaction between willing parties, other than
in a forced or liquidation sale. Selling expenses and potential taxes are not
included. The estimated fair value amounts were determined using available
market information, current pricing information and various

valuation methodologies. If quoted market prices were not readily available for
a financial instrument, management determined an estimated fair value.
Accordingly, the estimates may not be indicative of the amounts the financial
instruments could be exchanged for in a current or future market transaction.
 
The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate that
value:
 
CASH AND SHORT TERM INVESTMENTS: Carrying value is considered to be a reasonable
estimate of fair value.
 
BONDS, NOTES AND REDEEMABLE PREFERRED STOCKS: Fair value is based principally on
independent pricing services, broker quotes and other independent information.
 
MORTGAGE LOANS: Fair values are primarily determined by discounting future cash
flows to the present at current market rates, using expected prepayment rates.
 
COMMON STOCKS: Fair value is based principally on independent pricing services,
broker quotes and other independent information.
 
COST-METHOD PARTNERSHIPS: Fair value of limited partnerships accounted for by
using the cost method is based upon the fair value of the net assets of the
partnerships as determined by the general partners.
 
VARIABLE ANNUITY ASSETS: Variable annuity assets are carried at the market value
of the underlying securities.
 
RECEIVABLE FROM (PAYABLE TO) BROKERS FOR SALES (PURCHASES) OF SECURITIES: Such
obligations represent net transactions of a short-term nature for which the
carrying value is considered a reasonable estimate of fair value.
 
RESERVES FOR FIXED ANNUITY CONTRACTS: Deferred annuity contracts and single
premium life contracts are assigned a fair value equal to current net surrender
value. Annuitized contracts are valued based on the present value of future cash
flows at current pricing rates.
 
RESERVES FOR GUARANTEED INVESTMENT CONTRACTS: Fair value is based on the present
value of future cash flows at current pricing rates and is net of the estimated
fair value of hedging Swap Agreements, determined from independent broker
quotes.
 
VARIABLE ANNUITY LIABILITIES: Fair values of contracts in the accumulation phase
are based on net surrender values. Fair values of contracts in the payout phase
are based on the present value of future cash flows at assumed investment rates.
 
SUBORDINATED NOTES PAYABLE TO PARENT: Fair value is estimated based on the
quoted market prices for similar issues.

For United States federal income tax purposes, certain amounts from life
insurance operations are accumulated in a memorandum policyholders' surplus
account and are taxed only when distributed to shareholders or when such account
exceeds prescribed limits. The accumulated policyholders' surplus was
$14,300,000 at September 30, 1997. The Company does not anticipate any
transactions which would cause any part of this surplus to be taxable.
 
Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax reporting purposes. The significant
components of the liability for Deferred Income Taxes are as follows:

11. SUBSEQUENT EVENTS (UNAUDITED)
 
On May 27, 1998, SunAmerica agreed to contribute $200,000,000 of capital to the
Company's parent, which in turn agreed to contribute such amount to the Company.
Each contribution is subject to the provisions of a surplus note in favor of the
contributing company. A significant provision of each surplus note is that each
contributing company may withdraw its respective surplus contribution (up to an
amount equal to the economic effect of the coinsurance transaction described in
Note 3 below), upon closure of that coinsurance transaction. Such capital was
withdrawn in August 1998.
 
On August 11, 1998, the Company entered into a modified coinsurance transaction,
approved by the Arizona Department of Insurance, which involves the ceding of
approximately $5,000,000,000 of variable annuities to ANLIC Insurance Company
(Cayman), a Cayman Islands stock life insurance company. As a part of this
transaction, the Company received cash amounting to approximately $188,700,000,
and recorded a corresponding reduction of deferred acquisition costs related to
the coinsured annuities.
 
On July 15, 1998, the Company entered into a definitive agreement to acquire the
individual life business and the individual and group annuity business of MBL
Life Assurance Corporation ("MBL Life") via a 100% coinsurance transaction for
approximately $130,000,000 in cash. The transaction will include approximately
$2,000,000,000 of universal life reserves and $3,000,000,000 of fixed annuity
reserves. The Company plans to reinsure a large portion of the mortality risk
associated with the acquired block of universal life business. Completion of
this acquisition is expected by the end of calendar year 1998 and is subject to
customary conditions and required approvals. Included in this block of business
is approximately $250,000,000 of individual life business and $500,000,000 of
group annuity business whose contractowners are residents of New York State
("the New York Business"). Approximately six months subsequent to completion of
the transaction, the New York Business will be acquired by the Company's New
York affiliate, First SunAmerica Life Insurance Company, and the remainder of
the business will be acquired by the Company via assumption reinsurance
agreements between MBL Life and the respective companies, which will supersede
the coinsurance agreement. The $130,000,000 purchase price will be allocated
between the Company and its affiliate based on their respective assumed
reserves.
