MULTI-STYLE EQUITY FUND
 
PORTFOLIO MANAGEMENT DISCUSSION
 
December 31, 1998 (Unaudited)



PERFORMANCE REVIEW

For the year ended December 31, 1998, the Multi-Style Equity Fund shares
reflected a total return of 28.7%, as compared to the Russell 1000(R) Index
results of 27%. The Fund exceeded the Index primarily due to effective security
selection. Performance also compared very favorably with the 15.3% average
return of mutual funds tracked in the Lipper(R) Growth and Income Funds
Benchmark.
 
PORTFOLIO HIGHLIGHTS

The performance of stocks in 1998 was characterized by unprecedented differences
in returns between various sectors of the market. Stocks provided investors with
returns in excess of 20% -- the first time the market has ever produced four
consecutive years of gains in excess of 20% per annum. Despite the market's
strength, volatility was extreme, with a deep swoon in prices during the third
quarter. The market's advance favored large cap growth issues. Valuation
sensitivity proved a liability for investors, as value stocks in the Russell
1000 Index trailed their growth counterparts by more than 20 percentage points -
the largest differential since the inception of the indices. Technology stocks
led the market advance, as anything and everything associated with the Internet
attracted investors. As a result, the technology sector gained 75% for the year.
The laggards were led by energy and raw materials, as commodity prices trended
lower throughout the year. Large cap issues dominated once again with the
largest 50 stocks of the Russell 1000 Index up 40%, while small cap stocks in
the Russell 2000(R) Index fell 2.5% during the year-another unprecedented
margin.
 
The Multi-Style Equity Fund fared better than the majority of its peers in the
Lipper(R) Growth and Income Funds Benchmark in 1998. Its multi-manager mix
afforded it some opportunities not shared by funds with more focused approaches
to the growth and income style. The Fund's growth manager, Alliance, produced
very strong results, aided by exposure to many of the market's strongest
performers. However, even with their aggressive style, they found valuations on
many other stocks unacceptably high. The value-oriented manager, Equinox, had a
more difficult time as their valuation sensitivity focused their investments
away from some of the better performing sectors of the market. They were
underweighted in many of the more aggressively-priced growth stocks,
particularly Internet-related issues. Overall, good security selection,
particularly in the Technology sector, helped the Fund outperform its
benchmarks.

AGGRESSIVE EQUITY FUND
 
PORTFOLIO MANAGEMENT DISCUSSION
 
December 31, 1998 (Unaudited)


PERFORMANCE REVIEW
For the year ended December 31, 1998, the Aggressive Equity Fund reflected a
total return of 1% as compared to the Russell 2500(TM) Index, which gained only
0.4%. The Fund's performance was also better than the average small cap fund
tracked by Lipper(R) Analytical Services which lost 0.6%. Good security
selection was the primary factor in achieving positive returns.
 
PORTFOLIO HIGHLIGHTS
Small capitalization stocks lagged large cap issues throughout 1998. The
market's defense against weakening trends in the global economy was to focus on
stocks believed to have better financial strength and growth. The Russell
2000(R) Index lost 2.5% for the year while the largest stocks in the Russell
1000(R) Index gained more than 40% - an unprecedented spread. Despite the
relative outperformance of growth-oriented funds in the fourth quarter, the
Aggressive Equity Fund produced good index-relative results for the year,
finishing slightly ahead of the Russell 2500 Index and well ahead of the average
small cap fund tracked by Lipper. The managers' security selection accounted for
the superior performance. Results were particularly good in the Consumer
Discretionary sector, led by retail holdings.
 
Investment style also had a strong influence on performance in the small cap
market. While small growth stocks were up slightly for the year, small value
stocks finished in negative territory. The Russell 2000(R) Growth Index rose
1.2% during the year, while the Russell 2000(R) Value Index fell 6.5%. The
Aggressive Equity Fund's performance was reflective of the good security
selection of its underlying managers. Particularly good results were produced by
the Fund's Consumer Discretionary holdings, specifically specialty retailers Ann
Taylor and Talbot's. The managers' stock picking was also effective in avoiding
some of the weakness in the Materials and Processing and the Financial Services
sectors.

PORTFOLIO MANAGEMENT DISCUSSION
 
December 31, 1998 (Unaudited)
 
 
 
OBJECTIVE: To provide favorable total return and additional diversification for
US investors by investing primarily in equity and fixed-income securities of
non-US companies, and securities issued by non-US governments.
 
INVESTS IN: Primarily the equity securities of non-US companies in developed
foreign markets.
 
STRATEGY: The Fund uses a multi-manager strategy intended to achieve higher
returns than its benchmark index with moderate risk by employing the investment
management services of three managers with separate and distinct investment
approaches. The Fund's primary source of added value is intended to be stock
selection with only moderate country allocations relative to the index to
capture the diversification benefits of international investment in an asset
allocation context.

PORTFOLIO MANAGEMENT DISCUSSION
 
December 31, 1998 (Unaudited)



PERFORMANCE REVIEW
For the year ended December 31, 1998, the Non-US Fund had a total return of 13%
as compared to the Salomon Smith Barney Broad Market Index ex-US, which gained
17.2% for the year. The Fund's shortfall to the benchmark was primarily due to
its underweighting in large capitalization stocks during a year in which large
caps outperformed globally.
 
PORTFOLIO HIGHLIGHTS
Dominant trends in the non-US developed markets were similar to those evident in
the US market. Investors showed a strong preference for larger cap issues as a
defensive investment amid fears of deteriorating global economic fundamentals.
For this reason, growth-oriented investments fared better. On the surface,
international market performance looked quite similar to 1997, with continental
European markets the strongest performers. The European Monetary Union continued
to foster optimism in the stock market. The United Kingdom performed well, but
lagged the majority of its European Union neighbors. Asian markets posted strong
fourth quarter gains due to strong currency appreciation, but were generally
poor performers during the year.
 
Underweightings in large cap issues and growth stocks resulted in the Fund
trailing the benchmark. The Fund's managers struggled for much of the year with
security selection, with weak results from Japanese stocks plaguing the Fund
through the first three quarters. Lack of exposure to large cap, growth stock in
continental European markets had the greatest impact late in the year.
Performance also reflected the Fund's limited exposure to high valuation, growth
stocks over the course of the year, as J.P. Morgan's valuation disciplines
discouraged their purchase. Despite these setbacks, the Fund finished the year
ahead of the average international fund tracked by Lipper, which gained 12.9%.

++++ Salomon Smith Barney BMI Index ex-US is a comprehensive float-weighted
     equity index consisting of every company with an investable market
     capitalization of over $100 million in 22 countries. This Index has broader
     representation than the MSCI EAFE Index. However, 10 years of historical
     performance information is not available because it was constructed on June
     30, 1989.
 (S)  Annualized.
 
Performance is historical and assumes reinvestment of all dividends and capital
gains. Investment return and principal value will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than when purchased.
Past performance is not indicative of future results.

PORTFOLIO MANAGEMENT DISCUSSION
 
December 31, 1998 (Unaudited)


PERFORMANCE REVIEW

For the year ended December 31, 1998, the Core Bond Fund shares reflected a
total return of 7.4%, as compared to the Lehman Brothers Aggregate Bond Index,
which gained 8.7%. The Index outperformed primarily due to the Fund's emphasis
on yield sectors, which lagged treasuries in virtually all categories after
severe credit spread widening during the third quarter.
 
PORTFOLIO HIGHLIGHTS

Bonds produced returns slightly above long-term expectations in 1998. Falling
yields and a flight to quality resulted in the outperformance of US treasuries
relative to other sectors of the US bond market during the year. Spread sectors,
including corporate bonds and mortgage- and asset-backed securities lagged due
to severe credit spread widening during the third quarter. After trending toward
historic lows over the past few years, credit spreads widened to their largest
level in two decades, driven by increasing fears of a global recession. The
Federal Reserve Board intervened during the third and fourth quarters, applying
three separate interest rate cuts, which added a degree of liquidity to the
market. Although this helped restore confidence, the subsequent narrowing of
spreads failed to fully offset third quarter widening.
 
Given their emphasis on spread sectors to add value, the unexpectedly sudden and
dramatic widening of credit spreads during the third quarter eroded the
performance of most bond funds. The Core Bond Fund, which was overweighted in
lower quality corporates and mortgage-backed securities relative to the Lehman
Aggregate Bond Index, also found this to be true. Effective security selection
and yield curve strategies helped offset some of the impact on the fund's
performance since the fund also held longer duration securities than the Index
for much of the year.

RUSSELL INSURANCE FUNDS
 
NOTES TO FINANCIAL STATEMENTS
 
December 31, 1998

1.   ORGANIZATION

     Russell Insurance Funds (the "Investment Company") is a series mutual fund
     with four investment portfolios, referred to as "Funds." These financial
     statements report on the Funds, each of which has distinct investment
     objectives and strategies. These Funds are offered at net asset value to
     qualified insurance company separate accounts offering variable insurance
     products. The Investment Company is registered under the Investment Company
     Act of 1940, as amended, as a diversified, open-end management investment
     company. It is organized and operates as a Massachusetts business trust
     under a master trust agreement dated July 11, 1996. The Investment
     Company's master trust agreement permits the Board of Trustees to issue an
     unlimited number of full and fractional shares of beneficial interest at a
     $.01 par value.
 
2.   SIGNIFICANT ACCOUNTING POLICIES

     The Funds' financial statements are prepared in accordance with generally
     accepted accounting principles ("GAAP") which require the use of management
     estimates. The following is a summary of the significant accounting
     policies consistently followed by the Funds in the preparation of these
     financial statements.
 
     SECURITY VALUATION: United States equity and fixed-income securities listed
     and traded principally on any national securities exchange are valued on
     the basis of the last sale price or, lacking any sale, at the closing bid
     price, on the primary exchange on which the security is traded. United
     States over-the-counter equity and fixed-income securities and options are
     valued on the basis of the closing bid price. Futures contracts are valued
     on the basis of the last sale price. Many fixed-income securities do not
     trade each day and, thus, last sale or bid prices are frequently not
     available. Fixed income securities, therefore, may be valued using prices
     provided by a pricing service when such prices are believed to reflect the
     fair market value of such securities.
 
     International equity and fixed income securities traded on a national
     securities exchange are valued on the basis of the last sale price.
     International securities traded over the counter are valued on the basis of
     the mean of bid prices. In the absence of a last sale or mean bid price,
     respectively, such securities may be valued on the basis of prices provided
     by a pricing service if those prices are believed to reflect the fair
     market value of such securities.
 
     Short-term investments maturing within 60 days of the valuation date are
     valued at amortized cost unless the Board of Trustees determines that
     amortized cost does not represent fair value.
 
     The Funds may value certain securities for which market quotations are not
     readily available at "fair value," as determined in good faith pursuant to
     procedures established by the Board of Trustees.
 
     INVESTMENT TRANSACTIONS: Securities transactions are recorded on a trade
     date basis. Realized gains and losses from securities transactions are
     recorded on the basis of specific identified cost incurred by each money
     manager within a particular fund. The Funds may lend portfolio securities
     but have not done so in 1998.
 
     INVESTMENT INCOME: Dividend income is recorded on the ex-dividend date and
     interest income is recorded on the accrual basis.
 
     AMORTIZATION AND ACCRETION: All premiums and discounts, including original
     issue discounts, for the Funds are amortized/ accreted for both tax and
     financial reporting purposes.
 
     FEDERAL INCOME TAXES: As a Massachusetts business trust, each Fund is a
     separate corporate taxpayer and determines its net investment income and
     capital gains (or losses) and the amounts to be distributed to each Fund's
     shareholders without regard to the income and capital gains (or losses) of
     the other Funds.
 
     It is each Fund's intention to qualify as a regulated investment company
     and distribute all of its taxable income. Therefore, no federal income tax
     provision was required for the Funds. From November 1, 1998 to December 31,
     1998, the Aggressive Equity and Non-US Funds incurred net realized capital
     losses of $15,508 and $13,235, respectively. As permitted by tax
     regulations, the Aggressive Equity and Non-US Funds intend to elect to
     defer these losses and treat them as arising in the year ending December
     31, 1999.
 
     At December 31, 1998, the Non-US Fund had a net tax basis capital loss
     carryforward of $570,615 which may be applied against any net realized
     taxable gains in each succeeding year or until its expiration date of
     December 31, 2006, whichever occurs first.

</TABLE> 
 
     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS: For all Funds, income
     dividends and capital gain distributions, if any, are recorded on the
     ex-dividend date. Dividends are generally declared and paid quarterly,
     except for the Non-U.S. Fund, which generally declares and pays dividends
     annually. Capital gain distributions are generally declared and paid
     annually.
 
     The timing and characterization of certain income and capital gain
     distributions are determined in accordance with federal tax regulations
     which may differ from GAAP. As a result, net investment income and net
     realized gain (or loss) on investment and foreign currency-related
     transactions for a reporting period may differ significantly from
     distributions during such period. The differences between tax regulations
     and GAAP primarily relate to investments in options, futures, forward
     contracts, passive foreign investment companies, foreign-denominated
     investments, mortgage-backed securities, and certain securities sold at a
     loss. Accordingly, a Fund may periodically make a reclassification among
     certain of its capital accounts without impacting its net asset value.
 
     The following reclassifications have been made to reflect activity for the
     year ended December 31, 1998:
 
                        UNDISTRIBUTED         ACCUMULATED
                        NET INVESTMENT        NET REALIZED
                            INCOME            GAIN (LOSS)
                       ----------------      --------------
     Non-US                $88,390             $ (88,390)
     Core Bond               1,861                (1,861)

     EXPENSES: The Funds will pay their own expenses other than those expressly
     assumed by Frank Russell Investment Management Company ("FRIMCo" or
     "Advisor"). Most expenses can be directly attributed to the individual
     Funds. Expenses which cannot be directly attributed are allocated among all
     Funds principally based on their relative net assets.
 
     DEFERRED ORGANIZATION EXPENSES: Organization costs of the Funds have been
     deferred and are being amortized over 60 months on a straight-line basis.
 
     FOREIGN CURRENCY TRANSLATIONS: The books and records of the Funds are
     maintained in U.S. dollars. Foreign currency amounts and transactions of
     the Funds are translated into U.S. dollars on the following basis:
 
     (a)  Market value of investment securities, other assets and liabilities at
          the closing rate of exchange on the valuation date.
 
     (b)  Outstanding purchases and sales of investment securities and income at
          the closing rate of exchange prevailing on the respective trade dates
          of such transactions.
 
     Reported net realized gains or losses from foreign currency-related
     transactions arise from: sales and maturities of short-term securities;
     sales of foreign currencies; currency gains or losses realized between the
     trade and settlement dates on securities transactions; the difference
     between the amounts of dividends, interest, and foreign withholding taxes
     recorded on the Non-US Fund's books and the U.S. dollar equivalent of the
     amounts actually received or paid. Net unrealized gains or losses from
     foreign currency-related transactions arise from changes in the value of
     assets and liabilities, other than investments in securities, at
     period-end, as a result of changes in the exchange rates.

     It is not practical to isolate that portion of the results of operations of
     the Non-US Fund that arises as a result of changes in exchange rates from
     that portion that arises from changes in market prices of investments
     during the year. Such fluctuations are included with the net realized and
     unrealized gain or loss from investments. However, for federal income tax
     purposes the Non-US Fund does isolate the effects of changes in foreign
     exchange rates from the fluctuations arising from changes in market prices
     for realized gain (or loss) on debt obligations.
 
     DERIVATIVES: To the extent permitted by the investment objectives,
     restrictions and policies set forth in the Funds' Prospectus and Statement
     of Additional Information, the Funds may participate in various
     derivative-based transactions. Derivative securities are instruments or
     agreements whose value is derived from an underlying security or index.
     They include options, futures, swaps, forwards, structured notes and
     stripped securities. These instruments offer unique characteristics and
     risks that assist the Funds in meeting their investment strategies.
 
     The Funds typically use derivatives in three ways: cash equitization,
     hedging, and return enhancement. Cash equitization is a technique that may
     be used by certain Funds through the use of options and futures to earn
     market-like returns with their excess and liquidity reserve cash balances.
     Hedging is used by some funds to limit or control risks, such as adverse
     movements in exchange rates and interest rates. Return enhancement can be
     accomplished through the use of derivatives in a Fund. By purchasing
     certain instruments, Funds may more effectively achieve the desired
     portfolio characteristics that allow them to meet their investment
     objectives. Depending on how the derivatives are structured and utilized,
     the risks associated with them may vary widely. These risks are generally
     categorized as market risk, liquidity risk and counterparty or credit risk.
 
     FOREIGN CURRENCY EXCHANGE CONTRACTS: In connection with portfolio purchases
     and sales of securities denominated in a foreign currency, the Non-US Fund
     may enter into foreign currency exchange spot contracts and forward foreign
     currency exchange contracts ("contracts"). Contracts are recorded at market
     value. Certain risks may arise upon entering into these contracts from the
     potential inability of counterparties to meet the terms of their contracts
     and are generally limited to the amount of unrealized gain on the
     contracts, if any, that is recognized in the Statement of Assets and
     Liabilities. Realized gains or losses arising from such transactions are
     included in net realized gain (or loss) from foreign currency-related
     transactions.
 
     FORWARD COMMITMENTS: The Funds may contract to purchase securities for a
     fixed price at a future date beyond customary settlement time (not to
     exceed 120 days)(i.e., a "forward commitment," "delayed settlement" or
     "when issued" transaction, e.g., to be announced ("TBA")) consistent with a
     Fund's ability to manage its investment portfolio and meet redemption
     requests. The price of the underlying securities and the date when the
     securities will be delivered and paid for are fixed at the time the
     transaction is negotiated. The Funds may dispose of a forward commitment
     transaction prior to settlement if it is appropriate to do so and realize
     short-term gains (or losses) upon such sale. When effecting such
     transactions, cash or liquid high-grade debt obligations of the Fund in a
     dollar amount sufficient to make payment for the portfolio securities to be
     purchased will be segregated on the Fund's records at the trade date and
     maintained until the transaction is settled. A forward commitment
     transaction involves a risk of loss if the value of the security to be
     purchased declines prior to the settlement date or the other party to the
     transaction fails to complete the transaction.
 
     FUTURES CONTRACTS: The domestic and international equity Funds utilize
     futures to equitize liquidity reserve balances. The face or contract
     amounts of these instruments reflect the extent of the Funds' exposure to
     off balance sheet risk. The primary risks associated with the use of
     futures contracts are an imperfect correlation between the change in market
     value of the securities held by the Fund and the prices of futures
     contracts, and the possibility of an illiquid market. Changes in the
     initial settlement values of futures contracts are accounted for as
     unrealized appreciation (depreciation) until the contracts are terminated,
     at which time realized gains and losses are recognized.
 
     The Funds may invest in interest rate futures contracts, stock index
     futures contracts, and foreign currency futures contracts and options
     thereon that are traded on a United States or foreign exchange or board of
     trade.

REPORT OF INDEPENDENT ACCOUNTANTS
 
 
 
 
 
To the Board of Trustees and Shareholders
of Frank Russell Investment Company:
 
In our opinion, the accompanying statements of assets and liabilities, including
the statements of net assets, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of each of the series of Russell
Insurance Funds (comprised of Multi-Style Equity, Aggressive Equity, Non-U.S.,
and Core Bond (the "Funds")) at December 31, 1998, and the results of their
operations, the changes in their net assets and the financial highlights for the
periods indicated therein, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Funds'
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 investments owned at December 31, 1998 by correspondence with
the custodian and brokers, provide a reasonable basis for the opinion expressed
above.
