*Variable Annuity Unit Values reflect the Company's reduction of its mortality
 and expense risk charges at a rate of 1.20% per year instead of 1.25% per year
 throughout the 5/1/96 through 6/30/96 period. Had these charges been imposed,
 ending accumulation unit values would have been lower for those funds during
 that period.
 
 Accumulation Unit Values are net of charges against the assets of the Variable
 Account for the assumption of mortality and expense risks and for
 administrative expenses.

1.  ORGANIZATION
 
    CG Variable Annuity Separate Account II (the Account) is registered as a
Unit Investment Trust under the Investment Company Act of 1940, as amended. The
operations of the Account are part of the operations of Connecticut General Life
Insurance Company (CG Life). The assets and liabilities of the Account are
clearly identified and distinguished from other assets and liabilities of CG
Life. The assets of the Account are not available to meet the general
obligations of CG Life and are held for the exclusive benefit of the
participants. Within the account are four contract types that have different
contract terms and or different fees (See Note 4).
 
    The assets of the Account are divided into variable sub-accounts each of

    Effective January 1, 1998, CG Life sold its individual variable annuity
business to Lincoln National Corporation (Lincoln). Although CG Life will remain
responsible for all policy terms and conditions, Lincoln will be servicing the
individual annuity contracts, including the payment of benefits, oversight of
investment management and contract administration.
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
    These financial statements have been prepared in conformity with generally
accepted accounting principles. The preparation of financial statements in
accordance with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results could differ from those estimates.
The following is a summary of significant accounting policies consistently
followed in the preparation of the Account's financial statements.
 
A.  INVESTMENT VALUATION:--Investments held by the sub-accounts are valued at
    their respective closing net asset value per share as determined by the
    mutual funds as of December 31, 1997. The change in the difference between
    cost and value is reflected as unrealized gain (loss) in the Statements of
    Operations.
 
B.  INVESTMENT TRANSACTIONS:--Investment transactions are recorded on the trade
    date (date the order to buy or sell is executed). Realized gains and losses
    on sales of investments are determined by the last-in, first-out cost basis
    of the investment sold. Dividend and capital gain distributions are recorded
    on the ex-dividend date. Investment transactions are settled through CG
    Life.
 
C.  FEDERAL INCOME TAXES:--The operations of the Account form a part of, and are
    taxed with, the total operations of CG Life, which is taxed as a life
    insurance company. Under existing Federal income tax law, investment income
    (dividends) and capital gains attributable to the Account are not taxed.
 
D.  ANNUITY RESERVES:--The amount of annuity reserves is determined by the
    actuarial assumptions which meet statutory requirements. Gains or losses
    resulting from the actual mortality experience, the responsibility of which
    is assumed by CG Life, are offset by transfers to or from CG Life.

4.  CHARGES AND DEDUCTIONS
 
    CG Life assumes the risk that annuitants may live longer than expected and
also assumes a mortality risk in connection with the death benefits of the
contract. CG Life also assumes a risk that its actual administrative expenses
may be higher than amounts deducted for such expenses. For all contracts sold
after April 30, 1997, CG Life charges each variable sub-account the daily
equivalent of 1.25%, on an annual basis, of the current value of each
sub-account's assets for the assumption of these risks. All contracts sold
before May 1, 1997, with the exception of contracts sold in the state of New
York from May 1, 1996 to April 30, 1997 (1.25% annual fee), have an annual fee
of 1.20% for mortality and expense risks.
 
    CG Life also deducts a daily administrative fee from the assets of each
variable sub-account as partial reimbursement for administrative expenses
relating to the issuance and maintenance of the contract and the participant's
annuity

account. For all contracts sold after April 30, 1997, this charge is at an
effective annual rate of .15%. All contracts sold before May 1, 1997, with the
exception of contracts sold in the state of New York from May 1, 1996 to April
30, 1997 (.15% annual fee), have an effective annual rate of .10%.
 
    As partial compensation for administrative services provided, CG Life
additionally receives a $35 ($30 on New York contracts) annuity account fee per
year from each contract. This charge is deducted from the fixed or variable sub-
account of the participant or on a pro-rata basis from two or more fixed or
variable sub-accounts in relation to their values under the contract. Fixed
sub-accounts are part of the general account of CG Life and are not included in
these financial statements. The annuity account fee will be waived for any
contract year in which the annuity account value equals or exceeds $100,000 as
of the last valuation date of the contract year. Annuity account fees, for the
variable sub-accounts, amounting to $71,683, were deducted for the periods ended
December 31, 1997.
 
    For contracts sold prior to May 1, 1997 (excluding contracts sold in the
state of New York where the optional death benefit was not available), the
participant could have, for an additional charge, selected an optional death
benefit (optional death benefit fee). The optional death benefit fee will be
deducted from the participant's fixed or variable sub-account or on a pro-rata
basis from two or more fixed or variable sub-accounts in relation to their
values under the contract on the date of each contract anniversary. The optional
death benefit fees, for the variable sub-accounts, amounted to $4,356 for the
periods ended December 31, 1997.
 
    Under certain circumstances, CG Life reserves the right to charge a transfer
fee of up to $10 for transfers between sub-accounts. No transfer fees, for the
variable sub-accounts, were deducted for the periods ended December 31, 1997.

    No deduction for sales charges is made from a premium payment. However, if a
cash withdrawal is made, a withdrawal charge (contingent deferred sales charge)
may be assessed by CG Life. The withdrawal charge, if assessed, varies from 0-7%
depending upon the duration of each contract deposit. The withdrawal charge is
deducted from withdrawal proceeds for full withdrawals and reduces the remaining
account value for partial withdrawals. These charges are paid to CG Life as
reimbursement for services provided. These services include commissions paid to
sales personnel, the costs associated with preparation of sales literature and
other promotional costs and acquisition expenses. Withdrawal charges paid to CG
Life for the variable sub-accounts, for the periods ended December 31, 1997,
amounted to $145,226.

5.  DISTRIBUTION OF NET INCOME
 
    The Account does not expect to declare dividends to participants from
accumulated net income. The accumulated net income is distributed to
participants as part of surrenders, death benefits, transfers to other fixed or
variable sub-accounts or annuity payments in excess of net purchase payments.
 
6.  DIVERSIFICATION REQUIREMENTS
 
    Under the provisions of Section 817(h) of the Internal Revenue Code of 1986
(the Code), a variable annuity contract, other than a contract issued in
connection with certain types of employee benefit plans, will not be treated as
an annuity contract for Federal tax purposes for any period for which the
investments of the segregated asset account, on which the contract is based, are
not adequately diversified. The Code provides that the "adequately diversified"
requirement may be met if the underlying investments satisfy either a statutory
safe harbor test or diversification requirements set forth in regulations issued
by the Secretary of the Treasury. CG Life believes, based on assurances from the
mutual fund managers, that the mutual funds satisfy the requirements of the
regulations.

periods indicated, in conformity with generally accepted accounting principles.
These financial statements are the responsibility of the Account's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial 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, which included confirmation of securities at
December 31, 1997 by correspondence with the custodians, provide a reasonable
basis for the opinion expressed above.

2.  SIGNIFICANT ACCOUNTING POLICIES
 
    These financial statements have been prepared in conformity with generally
accepted accounting principles. The following is a summary of significant
accounting policies consistently followed in the preparation of the Account's
financial statements.
 
A.  INVESTMENT VALUATION:--Investments held by the sub-accounts are valued at
    their respective closing net asset value per share as determined by the
    mutual funds as of December 31, 1997. The change in the difference between
    cost and value is reflected as unrealized gain (loss) in the Statements of
    Operations.
 
B.  INVESTMENT TRANSACTIONS:--Investment transactions are recorded on the trade
    date (date the order to buy or sell is executed). Realized gains and losses
    on sales of investments are determined by the last-in, first-out cost basis
    of the investment sold. Dividend and capital gain distributions are recorded
    on the ex-dividend date. Investment transactions are settled through CIGNA
    Life.
 
C.  FEDERAL INCOME TAXES:--The operations of the Account form a part of, and are
    taxed with, the total operations of CIGNA Life, which is taxed as a life
    insurance company. Under existing Federal income tax law, investment income
    (dividends) and capital gains attributable to the Account are not taxed.

4.  CHARGES AND DEDUCTIONS
 
    CIGNA Life assumes the risk that annuitants may live longer than expected
and also assumes a mortality risk in connection with the death benefits of the
contract. CIGNA Life also assumes a risk that its actual administrative expenses
may be higher than amounts deducted for such expenses. CIGNA Life charges each
variable sub-account the daily equivalent of 1.20%, on an annual basis, of the
current value of each sub-account's assets for the assumption of these risks.
 
    CIGNA Life also deducts a daily administrative fee from the assets of each
variable sub-account as partial reimbursement for administrative expenses
relating to the issuance and maintenance of the contract and the participant's
annuity account. This charge is currently at an effective annual rate of .10%.
 
    As partial compensation for administrative services provided, CIGNA Life
additionally receives a $35 annuity account fee per year from each contract.
This charge is deducted from the fixed or variable sub-account of the
participant or on a pro-rata basis from two or more fixed or variable
sub-accounts in relation to their values under the contract. Fixed sub-accounts
are part of the general account of CIGNA Life and are not included in these
financial statements. The annuity account fee will be waived for any contract
year in which the annuity account value equals or exceeds $100,000 as of the
last valuation date of the contract year. Annuity account fees, for the variable
sub-accounts, amounting to $16,358, were deducted for the year ended December
31, 1997.
 
    For an additional charge (optional death benefit fee), an optional death
benefit may be selected by the participant. The optional death benefit fee will
be deducted from the participant's fixed or variable sub-account or on a
pro-rata basis from

    No deduction for sales charges is made from a premium payment. However, if a
cash withdrawal is made, a withdrawal charge (contingent deferred sales charge)
may be assessed by CIGNA Life. The withdrawal charge, if assessed, varies from
0-7% depending upon the duration of each contract deposit. The withdrawal charge
is deducted from withdrawal proceeds for full withdrawals and reduces the
remaining account value for partial withdrawals. These charges are paid to CIGNA
Life as reimbursement for services provided. These services include commissions
paid to sales personnel, the costs of preparation of sales literature and other
promotional costs and acquisition expenses. Withdrawal charges paid to CIGNA
Life for the variable sub-accounts, for the year ended December 31, 1997,
amounted to $18,345.

CIGNA VARIABLE ANNUITY SEPARATE ACCOUNT I
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1997
- --------------------------------------------------------------------------------
 
5.  DISTRIBUTION OF NET INCOME
 
    The Account does not expect to declare dividends to participants from
accumulated net income. The accumulated net income is distributed to
participants as part of surrenders, death benefits, transfers to other fixed or
variable sub-accounts or annuity payments in excess of net purchase payments.
 
6.  DIVERSIFICATION REQUIREMENTS
 
    Under the provisions of Section 817(h) of the Internal Revenue Code of 1986
(the Code), a variable annuity contract, other than a contract issued in
connection with certain types of employee benefit plans, will not be treated as
an annuity contract for Federal tax purposes for any period for which the
investments of the segregated asset account, on which the contract is based, are
not adequately diversified. The Code provides that the "adequately diversified"
requirement may be met if the underlying investments satisfy either a statutory
safe harbor test or diversification requirements set forth in regulations issued
by the Secretary of the Treasury. CIGNA Life believes, based on assurances from
the mutual fund managers, that the mutual funds satisfy the requirements of the
regulations.

To the Board of Directors of CIGNA
Life Insurance Company and Participants of the
CIGNA Variable Annuity Separate Account I
 
In our opinion, the accompanying statements of assets and liabilities and the
related statements of operations and of changes in net assets present fairly, in
all material respects, the financial position of each of the sub-accounts, Alger
American Fund--Alger American Growth Portfolio, Alger American Leveraged AllCap
Portfolio, Alger American MidCap Growth Portfolio, Alger American Small
Capitalization Portfolio; Fidelity Variable Insurance Products
Fund--Equity-Income Portfolio, High Income Portfolio, Money Market Portfolio,
Overseas Portfolio; Fidelity Variable Insurance Products Fund II--Asset Manager
Portfolio, Investment Grade Bond Portfolio; MFS Variable Insurance Trust--MFS
Total Return Series, MFS Utilities Series, MFS World Governments Series;
Neuberger & Berman Advisers Management Trust--AMT Balanced Portfolio, AMT
Limited Maturity Bond Portfolio, AMT Partners Portfolio; OCC Accumulation
Trust--OCC Global Equity Portfolio, OCC Managed Portfolio, OCC Small Cap
Portfolio (constituting the CIGNA Variable Annuity Separate Account I, hereafter
referred to as "the Account") at December 31, 1997, the results of each of their
operations for the year then ended and the changes in each of their net assets
for the periods indicated, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Account's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
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, which included
confirmation of securities at December 31, 1997 by correspondence with the
custodians, provide a reasonable basis for the opinion expressed above.

- --------------------------------------------------------------------------------
 
1. ORGANIZATION
 
    CG Variable Life Insurance Separate Account I (the Account) is registered as
a Unit Investment Trust under the Investment Company Act of 1940, as amended.
The operations of the Account are part of the operations of Connecticut General
Life Insurance Company (CG Life). The assets and liabilities of the Account are
clearly identified and distinguished from other assets and liabilities of CG
Life. The assets of the Account are not available to meet the general
obligations of CG Life and are held for the exclusive benefit of the
participants.
 
    The assets of the Account are divided into variable sub-accounts each of
which is invested in shares of one of sixteen portfolios (mutual funds) of six
diversified open-end management investment companies, each portfolio with its
own investment objective. The variable sub-accounts are:
 
    ALGER AMERICAN FUND:--
 
        Alger American Growth Portfolio
 
        Alger American Leveraged AllCap Portfolio
 
        Alger American MidCap Growth Portfolio

servicing the individual life insurance contracts, including the payment of

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
A.  INVESTMENT VALUATION:--Investments held by the variable sub-accounts are
    valued at their respective closing net asset values per share as determined
    by the mutual funds as of December 31, 1997. The change in the difference
    between cost and value is reflected as unrealized gain (loss) in the
    Statements of Operations.
 
B.  INVESTMENT TRANSACTIONS:--Investment transactions are recorded on the trade
    date (date the order to buy or sell is executed). Realized gains and losses
    on sales of investments are determined by the last-in, first-out cost basis
    of the investment sold. Dividend and capital gain distributions are recorded
    on the ex-dividend date. Investment transactions are settled through CG
    Life.
 
C.  FEDERAL INCOME TAXES:--The operations of the Account form a part of, and are
    taxed with, the total operations of CG Life, which is taxed as a life
    insurance company. Under existing Federal income tax law, investment income
    (dividends) and capital gains attributable to the Account are not taxed.

4. CHARGES AND DEDUCTIONS
 
    CG Life charges each variable sub-account, for mortality and expense risks,
a daily deduction, equivalent to .45% per year during the first ten policy years
and .25% per year thereafter. The mortality and expense risk charges, for each
sub-account, are reported on the Statements of Operations.
 
    CG Life deducts a premium load of 3.5% of each premium payment to cover
state taxes and Federal income tax liabilities.
 
    CG Life charges a monthly administrative fee of $15 in the first policy year
and $5 in subsequent policy years. This charge is for items such as premium
billing and collection, policy value calculation, confirmations and periodic
reports.
 
    CG Life charges a monthly deduction for the cost of insurance and any
charges for supplemental riders. The cost of insurance charge depends on the
attained age, risk classification, gender classification (in accordance with
state law) and the current net amount at risk. On a monthly basis, the
administrative fee and the cost of insurance charge are deducted proportionately
from the value of each variable sub-account and/or the fixed account funding
option. The fixed account is part of the general account of CG Life and is not
included in these financial statements.
 
    Under certain circumstances, CG Life reserves the right to charge a transfer
fee of up to $25 for transfers between sub-accounts. Transfer fees, for the
variable sub-accounts, amounted to $25 for the year ended December 31, 1997.

</TABLE>
 
    CG Life, upon full surrender of a policy, may charge a surrender charge.
This charge is in part a deferred sales charge and in part a recovery of certain
first year administrative costs. The amount of the surrender charge, if any,
will depend on the amount of the death benefit, the amount of premium payments
made during the first two policy years and the age of the policy. In no event
will the surrender charge exceed the maximum allowed by state or Federal law. No
surrender charge is imposed on a partial surrender, but an administrative fee of
$25 is imposed, allocated pro-rata among the variable sub-accounts (and, where
applicable, the fixed account) from which the partial surrender proceeds are
taken. No full surrender charges or partial surrender administrative charges
were paid to CG Life, attributable to the variable sub-accounts, for the year
ended December 31, 1997.
 
5. DISTRIBUTION OF NET INCOME
 
    The Account does not expect to declare dividends to participants from
accumulated net income. The accumulated net income is distributed to
participants as part of death benefits, surrenders, and transfers to other fixed
or variable sub-accounts.
 
6. DIVERSIFICATION REQUIREMENTS
 
    Under the provisions of Section 817(h) of the Internal Revenue Code of 1986
(the Code), a variable life insurance policy will not be treated as life
insurance under Section 7702 of the Code for any period for which the
investments of the segregated asset account, on which the policy is based, are
not adequately diversified. The Code provides that the "adequately diversified"
requirement may be met if the underlying investments satisfy either a statutory
safe harbor test or diversification requirements set forth in regulations issued
by the Secretary of Treasury. CG Life believes, based on assurances from the
mutual fund managers, that the mutual funds satisfy the requirements of the
regulations.

In our opinion, the accompanying statements of assets and liabilities and the
related statements of operations and of changes in net assets present fairly, in
all material respects, the financial position of each of the sub-accounts, Alger
American Fund--Alger American Growth Portfolio, Alger American Leveraged AllCap
Portfolio, Alger American MidCap Growth Portfolio, Alger American Small

Accumulation Trust--OCC Global Equity Portfolio, OCC Managed Portfolio, OCC
Small Cap Portfolio (constituting the CG Variable Life Insurance Separate
Account I, hereafter referred to as "the Account") at December 31, 1997, the
results of each of their operations for the year then ended and the changes in
each of their net assets for the periods indicated, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Account's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial 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, which included confirmation of securities at December 31, 1997 by
correspondence with the custodians, provide a reasonable basis for the opinion
expressed above.
