DEAR SHAREHOLDER:

     The final half of 1998 was extraordinarily eventful for the capital markets
and your mutual fund.  As your new President I am pleased to report that despite
much market  turmoil your fund not only  survived the storm but thrived as well.
The final half of 1998 started  auspiciously as concerns over corporate earnings
sent both equity and bond markets tumbling in both July and August. However, two
interest  rate  reductions  engineered  by The  Federal  Reserve  Bank helped to
alleviate  these  concerns.  As the year came to a close it became more apparent
that economic  growth was solid and inflation  has remained  subdued.  Full year
1998 economic  growth was about 3.9%,  which along with the 3.9% growth in 1997,
was the  fastest  growth rate since 1984.  Inflation,  measured by the  consumer
price index,  was 1.6%,  the lowest since 1986 and second  lowest since 1964. 

     As reported  elsewhere in this report your funds have achieved returns that
continue to be very gratifying. The WT Money Market Portfolio posted a return of
5.49% for the calendar  year of 1998.  By  comparison,  the average money market
fund as  measured  by Lipper,  Inc.  posted a return of 4.86%.  Your fund ranked
among the top 2% of mutual funds in this  category.  

     Your WT  Short/Intermediate  Bond Portfolio benefited from reduced interest
rates during the year and returned  8.10% for the year  compared with an average
return of 6.60% for the  appropriate  Lipper,  Inc.  category.  While  this fund
underperformed  the Lehman  Intermediate  Government/Corporate  Index  return of
8.44%, it  nevertheless  ranked among the top 7% of its peer universe last year.

     The WT Broad  Market  Equity  Portfolio  return  was  29.66%  for the year,
compared  with the  Standard  and Poors 500 Index  return of 28.58%.  The fund's
investment strategy of focusing on well positioned,  well capitalized  companies
has continued to provide dividends.  Last year,  according to Lipper,  Inc., the
average growth oriented mutual fund rose by 22.86%.  Your WT Broad Market Equity
Portfolio  ranked  among the top  one-third  of nearly 1000 funds in the Lipper,
Inc. growth equity category.  

     Future investment direction for your fund is being positively influenced by
the economic  environment,  it is your investment advisors intent to continue to
focus on companies  with strong  earnings and balance sheet  fundamentals.  This
strategy has a proven track record and will continue to be emphasized.  

ECONOMIC OUTLOOK 

     The U.S.  economy  ended  1998 on a strong  note  with the  Gross  Domestic
Product exhibiting an annualized growth rate of 5.6% for the final quarter and a
3.9% rate for the  entire  year.  Last year was the  sixth  consecutive  year of
economic  growth in the U.S.  and the second  longest  expansion  in the postwar
period  fueled,  for the most part, by consumer  confidence  and  spending.  The
unemployment  rate is at its lowest  point since  1970,  inflation  is low,  and
consumer  wealth and  confidence  have long been buoyed by the strength in stock
prices--we  expect  consumer  spending  to  remain  robust  as a result of these
variables.  The real questions for 1999 are whether there will be  international
economic  recovery or more  turmoil  and how this will affect the U.S.  economy.
Internationally,  the key  areas  to  watch  will be  Japan  and the rest of the
Pacific Basin, Russia, Europe, Brazil and Mexico. Yet, despite the uncertainties
that exist  overseas,  we expect the U.S.  economy to exhibit  growth in 1999 of
approximately  2.5%,  inflation to hover  unchanged  at around  1.5%,  corporate
profits to grow  approximately  5-7% and year-end interest rates to be virtually
flat from the beginning of the year. 

EQUITY OUTLOOK 

     After four exceptional years of equity performance,  we are cautious in our
equity  forecast  for  1999.  On the  positive  side,  we see  little  chance of
inflation  rising--such  an event would quickly  damage the equity market as low
interest rates have supported the historically high valuations.  We also believe
that  corporate  earnings  will still be positive due to 2.5% growth in the U.S.
economy,  easier  comparisons  to  1998 in the  basic  materials  and  financial
sectors, and a better overseas economic environment for U.S. exporters.  For the
year,  we  expect  earnings  growth  to be in the 5 to 7%  range.  With a stable
interest  rate  environment,  we expect the U.S.  market to show a modest single
digit gain for 1999.  We believe the  best-performing  stocks will be those that
can  continue to  generate  top-line  revenue  growth in a  low-growth  economic
environment.  Those  companies  that continue to cut costs  without  restricting
growth will also be rewarded.

                                       1

FIXED INCOME OUTLOOK

     We do not foresee a great deal of interest rate movement in the bond market
during the coming  year based on slower  economic  growth and benign  inflation.
While  there  will  be  areas  in  our  economy  justifying  higher  rates,  low
unemployment  and  a  strong  housing  market,  they  will  be  offset  by  slow
international  growth.  The Federal Reserve could ease its monetary policy again
early in 1999 if  economic  growth  is tepid,  but by the end of the year,  this
posture could change in the face of a better  economic  setting.  Therefore,  we
remain  positive  toward  bonds at the  outset of the year and  would  focus our
interest in high-quality,  intermediate-term,  3 to 10 year, taxable or tax-free
issues.  We expect to see another good year of supply in the  municipal  markets
but think any talk of tax reform  could fall  victim to the  bitterness  created
over the Presidential impeachment process.

                                    Sincerely,
                                    
                                    [/S/ Robert J. Christian]

WT MUTUAL FUND
  NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED)
================================================================================

1.   DESCRIPTION  OF THE FUND.  The WT Mutual Fund (the  "Fund"),  formerly  the
     Kiewit Mutual Fund, is registered under the Investment  Company Act of 1940
     (the "1940 Act") as an open-end management  investment company organized as
     a Delaware business trust on June 1, 1994. The Declaration of Trust permits
     the Trustees to establish  additional  series,  each of which is a separate
     class of  shares.  The  Fund  currently  has  three  series  of  shares  in
     operation: the WT Money Market Portfolio (formerly the "Kiewit Money Market
     Portfolio"), the WT Short/Intermediate Bond Portfolio (formerly the "Kiewit
     Intermediate-Term Bond Portfolio") and the WT Broad Market Equity Portfolio
     (formerly  the  "Kiewit  Equity   Portfolio")   (each,  a  "Portfolio"  and
     collectively,  the  "Portfolios").  Prior to December 6, 1994, the Fund was
     known as the Kiewit  Institutional  Fund. 

     The investment  objectives of the three  Portfolios are as follows:  the WT
     Money Market Portfolio is to provide high current income while  maintaining
     a stable  share  price;  the WT  Short/Intermediate  Bond  Portfolio  is to
     provide as high a level of current income  consistent with reasonable risk;
     the WT Broad  Market  Equity  Portfolio  is to  achieve  long-term  capital
     appreciation.  Unlike other investment companies which directly acquire and
     manage their own portfolio of securities,  each Portfolio  seeks to achieve
     its  investment  objective by investing all of its  investable  assets in a
     corresponding  series of  shares  of the  Trust,  an  open-end,  management
     investment   company  that  issues  series  of  shares   (individually  and
     collectively,  the "Series") having the same investment objective, policies
     and  limitations as each of the  Portfolios.  As of December 31, 1998, each
     Portfolio   owned   virtually  100%  of  the  ownership   interest  in  its
     corresponding  Series.  The  performance  of  the  Portfolios  is  directly
     affected by the performance of the Series. The financial  statements of the
     Trust,  including the Schedules of Investments,  are included  elsewhere in
     this  report and should be read in  conjunction  with the Fund's  Financial
     Statements.

2.   SIGNIFICANT  ACCOUNTING  POLICIES.  The  following  is  a  summary  of  the
     significant accounting policies of the Fund:

     SECURITY VALUATION.  Valuation of each Portfolio is based on the underlying
     securities held in the  corresponding  Series.  Each Portfolio is allocated
     its portion of the Series' securities market value based upon its ownership
     interest in the Series. Securities held by the Series which are listed on a
     securities  exchange  and for which market  quotations  are  available  are
     valued  at the last  quoted  sale  price of the day or, if there is no such
     reported  sale,  securities  are valued at the mean between the most recent
     quoted bid and asked prices.  Price  information  for listed  securities is
     taken from the exchange  where the security is primarily  traded.  Unlisted
     securities for which market  quotations are readily available are valued at
     the most recent bid prices. Securities with a remaining maturity of 60 days
     or less are valued at amortized  cost,  which  approximates  market  value,
     unless  the  Trust's  Board  of  Trustees  determines  that  this  does not
     represent  fair  value.  The  WT  Money  Market  Series  values  securities
     utilizing the amortized cost valuation method which is permitted under Rule
     2a-7 under the 1940 Act. This method involves valuing a portfolio  security
     initially at its cost and thereafter  adjusting for amortization of premium
     or accretion of discount to maturity. 

     FEDERAL INCOME TAXES.  Each  Portfolio is treated as a separate  entity for
     Federal  income tax purposes and each intends to continue  qualifying  as a
     "regulated  investment  company" under Subchapter M of the Internal Revenue
     Code of 1986, as amended (the "Internal  Revenue Code"),  and to distribute
     all of its taxable income to its shareholders. Therefore, no Federal income
     tax provision is required.  At June 30, 1998, the WT Money Market Portfolio
     had a net tax basis  capital loss  carryforward  available to offset future
     net capital gains of approximately $4,000, which will expire as follows:

                                          CAPITAL LOSS      EXPIRATION
                                          CARRYFORWARD         DATE
                                          -----------------------------
         WT Money Market Portfolio          $1,000          06/30/2004
                                             3,000          06/30/2006
                                                       
     INVESTMENT INCOME AND DISTRIBUTIONS TO SHAREHOLDERS.  The Portfolios record
     their share of the  respective  Series'  income,  expenses and realized and
     unrealized gains and losses daily. Additionally, each Portfolio records its
     own expenses as incurred.  Distributions to shareholders of each Portfolio,
     except WT Broad  Market  Equity  Portfolio,  are  declared  daily  from net
     investment income and paid to shareholders monthly. The Fund's policy is to
     distribute substantially all net investment income from the WT Broad Market
     Equity Portfolio  annually.  Distributions of net capital gains realized by
     each Portfolio will be made annually.

================================================================================

     DEFERRED ORGANIZATION COSTS.  Organization costs incurred by each Portfolio
     have been deferred and are being amortized using the  straight-line  method
     over a five-year period beginning on the date that each Portfolio commenced
     operations.  In the event that any of the initial shares of a Portfolio are
     redeemed  during  the  amortization  period  by  any  holder  thereof,  the
     redemption  proceeds  will  be  reduced  by  any  unamortized  organization
     expenses  in the same  proportion  as the  number of initial  shares  being
     redeemed bears to the number of initial  shares  outstanding at the time of
     such redemption.

     USE  OF  ESTIMATES  IN  THE  PREPARATION  OF  FINANCIAL   STATEMENTS.   The
     preparation of financial  statements in conformity with generally  accepted
     accounting principles requires management to make estimates and assumptions
     that affect the reported  amount of assets and  liabilities  at the date of
     the financial  statements and the reported amounts of revenues and expenses
     during  the  reporting  period.  Actual  results  could  differ  from those
     estimates.  

3.   INVESTMENT  TRANSACTIONS.  During the six-month  period ended  December 31,
     1998, cash contributed to (additions) and cash withdrawn from  (reductions)
     the respective Series were as follows:

4.   MANAGEMENT AND  ADMINISTRATION  FEE AND OTHER TRANSACTIONS WITH AFFILIATES.
     Effective  October 20, 1998,  Wilmington  Trust Company  ("WTC"),  a wholly
     owned subsidiary of Wilmington Trust Corporation,  serves as the investment
     manager to each Series of the Trust.  WTC  provides  the Trust with records
     concerning  WTC's  activities  which the Trust is required to maintain  and
     renders regular  reports to me Trust's  officers and the Board of Trustees.
     WTC also  selects  brokers and dealers to effect  securities  transactions.
     Under the  investment  management  agreement  between KIMC and the Trust on
     behalf of each Series,  the monthly fees of the Series are at the following
     annual rates of their  average  monthly net assets:  WT Money Market Series
     0.20%; WT Short/Intermediate  Bond Series 0.40%; and WT Broad Market Equity
     Series  0.70%.  Although  the  Portfolios  do not  directly pay WTC for its
     services under the investment management  agreement,  each Portfolio shares
     in its pro rata portion  allocated from its corresponding  Series.  WTC has
     agreed to waive all or a portion of its  management  fee and assume certain
     Portfolio  operating  expenses  (excluding taxes,  extraordinary  expenses,
     brokerage  commissions  and  interest)  in an amount that will limit annual
     operating expenses to not more than the following percentage of the average
     daily net assets of each Portfolio:  WT Money Market  Portfolio - 0.20%, WT
     Short/Intermediate  Bond  Portfolio  - 0.50%;  and WT Broad  Market  Equity
     Portfolio - 0.80%.  These  undertakings  may be amended or rescinded at any
     time in the future. Prior to October 20, 1998, Kiewit Investment Management
     Corp. ("KIMC"),  a wholly owned subsidiary of Kiewit Construction  Company,
     provided the  management  services.  

     Effective  October  20,  1998,  the  Fund  entered  into an  Administrative
     Services  Agreement  with WTC.  Pursuant to this  agreement,  WTC  performs
     various  services,  including:  supervision of the services provided by the
     Fund's  custodian,  transfer and dividend  disbursing  agent and others who
     provide  services to the Fund for the benefit of the Portfolios;  providing
     shareholders  with information about the Portfolios and their investment as
     they or the  Fund may  request;  assisting  the  Portfolios  in  conducting
     meetings  of the  shareholders;  furnishing  information  as the  Board  of
     Trustees may require  regarding  the  corresponding  Series;  and any other
     administrative  services  for the benefit of the  Portfolio as the Board of
     Trustees may reasonably request. For its services,  each Portfolio pays WTC
     a monthly fee equal to one-twelfth of 0.02% of the Portfolio's  average net
     assets.  Prior to  October  20,  1998,  KIMC  provided  the  administrative
     services.

     PFPC Inc. ("PFPC"), an indirect wholly-owned  subsidiary of PNC Bank Corp.,
     a multi-bank holding company, serves as Administrator to the Fund and Trust
     pursuant to separate Administration Agreements with the Fund and the Trust.
     As  Administrator,  PFPC is  responsible  for  services  such as  financial
     reporting, compliance monitoring and corporate management. For the services
     provided,  PFPC receives a monthly  administration  fee from the Trust,  on
     behalf  of  each  Series.  Each  Series  pays a  proportionate  share  of a
     complex-wide  annual fee of 0.015% of the Trust's  aggregate  total average
     daily  net  assets  in  excess of $125  million.  This  asset  based fee is
     determined  on a total  average  daily net asset  basis,  and is subject to
     prescribed minimums.

WT INVESTMENT TRUST I
- ---------------------
    NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED)
================================================================================

1. DESCRIPTION OF THE TRUST. The WT Investment  Trust I (the "Trust"),  formerly
   the Kiewit Investment  Trust, is registered under the Investment  Company Act
   of 1940  (the  "1940  Act")  as an  open-end  management  investment  company
   organized as a Delaware  business trust on January 23, 1997. The  Declaration
   of Trust permits the trustees to establish  additional series,  each of which
   is a separate class of shares. The Trust currently has three series of shares
   in  operation:  WT Money Market  Series  (formerly  the "Kiewit  Money Market
   Series"),   WT   Short/Intermediate   Bond  Series   (formerly   the  "Kiewit
   Intermediate-Term  Bond Series") and WT Broad Market Equity Series  (formerly
   the "Kiewit Equity Series")  (individually  and  collectively  referred to as
   "Series").  The investment objectives of the three Series are as follows: the
   WT Money Market Series is to provide high current income while  maintaining a
   stable share price,  the WT  Short/Intermediate  Bond Series is to provide as
   high a level of current income as is consistent with reasonable risk; and the
   WT Broad Market Equity Series is to achieve long-term capital appreciation.

2. SIGNIFICANT   ACCOUNTING  POLICIES.   The  following  is  a  summary  of  the
   significant  accounting  policies of the Trust.  The preparation of financial
   statements  in  conformity  with  generally  accepted  accounting  principles
   requires  management  to make  estimates  and  assumptions  that  affect  the
   reported  amount  of  assets  and  liabilities  at the date of the  financial
   statements  and the  reported  amounts of revenues  and  expenses  during the
   reporting period. Actual results could differ from those estimates.

   SECURITY  VALUATION.  Securities  held by the  Series  which are  listed on a
   securities  exchange and for which market quotations are available are valued
   at the last  quoted sale price of the day,  or, if there is no such  reported
   sale,  securities  are valued at the mean between the most recent  quoted bid
   and asked prices.  Price  information for listed securities is taken form the
   exchange  where the security is primarily  traded.  Unlisted  securities  for
   which market  quotations are readily  available are valued at the most recent
   bid  prices.  Securities  with a  remaining  maturity  of 60 days or less are
   valued at amortized cost, which approximates market value, unless the Trust's
   Board of Trustees  determines that this does not represent fair value. The WT
   Money Market Series values securities  utilizing the amortized cost valuation
   method  which is  permitted  under Rule 2a-7 under the 1940 Act.  This method
   involves  valuing a portfolio  security  initially at its cost and thereafter
   adjusting for amortization of premium or accretion of discount to maturity.

   FEDERAL  INCOME  TAXES.  Each Series is treated as a  partnership  entity for
   Federal income tax purposes. Any interest, dividends and gains or losses of a
   Series  will be  deemed  to  have  been  "passed  through"  to each  partner.
   Accordingly, no tax provision is recorded for the Trust Series.

   INVESTMENT  INCOME.  All of the net investment income (loss) and realized and
   unrealized gains and losses from the security  transactions are allocated pro
   rata among the investors in the Series on a daily basis.

   REPURCHASE AGREEMENTS.  Each Series, through the Trust's custodian,  receives
   delivery of the underlying  securities used to  collateralize  the repurchase
   agreements, the market value of which is required to be in an amount at least
   equal to 102% of the resale  price.  Wilmington  Trust Company  ("WTC"),  the
   Trust Manager,  is responsible for determining that the market value of these
   underlying  securities  is  maintained  at a level at least equal 102% of the
   resale price.  In the event of default of the obligation to  repurchase,  the
   Trust has the right to  liquidate  the  collateral  and apply the proceeds in
   satisfaction of the obligation. Provisions of each agreement require that the
   market  value of the  collateral  is  sufficient  in the  event  of  default;
   however,  in the event of default  or  bankruptcy  by the other  party to the
   agreement,  realization  and/or retention of the collateral may be subject to
   legal proceedings.

   CALL AND PUT OPTIONS. The WT Short/Intermediate  Bond Series and the WT Broad
   Market  Equity  Series each may write and/or  purchase  exchange-traded  call
   options and purchase exchange-traded put options on securities in the Series.
   When a Series writes a call option,  an amount equal to the premium  received
   is  reflected  as a liability.  The amount of the  liability is  subsequently
   "marked to market" to reflect the current market value of the option written.
   If an option which a Series has written expires on its stipulated  expiration
   date, or if a series enters into a closing purchase  transaction,  the Series
   realizes a gain (or loss if the cost of the closing  transaction  exceeds the
   premium received when the option is sold), and the liability  related to such
   option is  extinguished.  If a call  option  which a Series  has  written  is
   exercised, the Series realizes a gain or loss from the sale of the underlying
   security, and the proceeds from which are increased by the premium originally
   received.

    NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED) -- CONTINUED
================================================================================
   FUTURES TRANSACTIONS. Certain Series may enter into futures contracts subject
   to certain limitations.  Upon entering into a futures contract, the Series is
   required to deposit  cash or pledge  U.S.  Government  securities  as margin.
   Subsequent  payments,  which are dependent on the daily  fluctuations  in the
   value of the underlying  security or securities,  are made or received by the
   Series each day (daily variation margin) and are recorded as unrealized gains
   or losses until the contracts are closed.  When the contracts are closed, the
   Series  records a realized gain or loss equal to the  difference  between the
   proceeds from (or cost of) the closing  transaction  and the Series' basis in
   the  contracts.   Risks  of  entering  into  futures  contracts  include  the
   possibility  that there will not be a perfect price  correlation  between the
   futures contracts and the underlying securities, and that a lack of liquidity
   for futures  contracts could exist in the secondary  market,  resulting in an
   inability  to close a  futures  position  prior  to its  maturity  date.  The
   purchase of a futures  contract  involves  the risk that a Series  could lose
   more  than the  original  margin  deposit  required  to  initiate  a  futures
   transaction up to the amount of the contract.

   OTHER.  Investment  security  transactions  are accounted for on a trade date
   basis.  Each Series uses the specific  identification  method for determining
   realized gain and loss on  investments  for both financial and Federal income
