CALAMOS CONVERTIBLE PORTFOLIO
-----------------------------
A message from the President




          Dear Contract Owners:

                   The CALAMOS Convertible Portfolio available through the
          Kansas City Life Century II Variable Products gained 3.9% during the
          six-month period from January 1 through June 30, 2000.

                   In an economic environment of low inflation and low interest
          rates combined with a highly volatile stock market, the CALAMOS
          Convertible Portfolio performed very well against traditional market
          measures, the S&P 500 at -0.4% and the disappointing Nasdaq at
          -2.5%.(1) The Portfolio also compared favorably to the Value Line
          Convertible Index,(2) up 1.07 % for the same period, and in line with
          the Lehman Brothers Government/Corporate Bond Index, up4.2%.(3)

                   Because of their unique nature, convertibles are the strategy
          of choice at CALAMOS. Convertible bonds allow the holder of the bond
          to convert to the underlying common stock at any time. This feature
          offers the upside potential of the equity markets, while convertibles'
          fixed-income characteristics help provide downside protection.* Based
          on our disciplined investment process, which balances risk with
          reward, we seek opportunities that strive to preserve assets while
          providing excellent long-term performance.

                   Record levels of new convertibles have provided us with a
          wealth of opportunity. Ninety- two new issues totaling $35 billion
          came to market in the first six months of 2000 alone, outpacing the
          $40 billion record set for all of 1999. In addition, high-grade
          convertible issuance has rebounded in the last several months, helping
          to improve the overall credit distribution in the convertible market.

                   During the past six months, total assets under management for
          institutional and individually managed accounts by CALAMOS ASSET
          MANAGEMENT, INC., the advisor to the CALAMOS Convertible Portfolio,
          have grown to $5.6 billion. At the same time, we added staff and
          strengthened our infrastructure to respond to our growing number of
          clients and their expanding portfolios. Ever-advancing technological
          capabilities also benefited our research, enabling our portfolio
          managers to monitor over 500 companies and 1,600 convertible issues on
          a daily basis to help identify the most promising opportunities.



          * Convertible securities tend to appreciate less than equity
          securities in rising stock markets.

         MANAGEMENT REVIEW & OUTLOOK
         ---------------------------

         WHAT ARE CONVERTIBLE SECURITIES AND WHO SHOULD INVEST IN THEM?
         Convertible securities are hybrid securities that combine the
characteristics of both stocks and bonds with the option to convert the security
into a specified number of common stock shares. Therefore, they offer the
potential for excellent opportunities in both worlds, that is, participation in
the growth of a stock's value while earning income from the bond. The equity
component provides excellent upside return potential while the fixed-income
features help both to reduce downside risk and help preserve your assets. Of
course, there are also risks associated with investments in convertible
securities, such as the risk that the issuing company will become insolvent.

         In managing a convertible portfolio, risk/reward measures the
relationship of the portfolio's upside potential versus the potential downside
protection provided by convertibles' fixed-income characteristics. At CALAMOS,
we maintain a favorable risk/reward ratio by taking profits on convertibles that
have increased in price and become more equity sensitive and replacing them with
convertibles closer to par with stronger fixed-income features. This strategy
allows the funds to be appropriately aggressive while retaining defensive
characteristics.

         Since the performance of convertibles does not correlate directly to
that of the stock or bond markets, they may help diversify a portfolio. A
convertible portfolio may benefit moderately conservative investors who seek
fixed income with favorable risk characteristics while desiring equity
participation and the potential for capital appreciation.

         HOW DOES MANAGEMENT SELECT ISSUES FOR THE PORTFOLIO?
         Because convertibles share characteristics of both bonds and equities,
to analyze a convertible thoroughly is significantly more complex than looking
at either of its two components individually. But at CALAMOS, evaluating an
issue's bond and stock aspects is just the beginning. We must then assemble the
diverse building blocks into a cohesive portfolio.

         We approach this challenge with a disciplined, proprietary investment
process, the CALAMOS Convertible Evaluation System, supported by a series of
quantitative models we've built and tested over time. Each of its four steps
focuses on a specific element of the convertible candidate:

         1. PROTECTION OF PRINCIPAL. First, credit analysis plays a significant
role in evaluating convertible securities. In this step, we look strictly at the
fixed-income attributes to assess the potential protection of principal that the
proposed issue may offer.

         2. COMPANY GROWTH PROSPECTS. We analyze the underlying equity component
of the issue by quantifying the company's growth prospects: earnings potential,
cash flow return on capital, and expected return. This allows our analysts to
concentrate on management and other qualitative factors.

<PAGE>   5

         3. RISK/REWARD. Based on Contingent Claims Option Theory, the CALAMOS
Convertible Model determines the fair value of the security. It integrates the
credit and equity analyses with convertible evaluation to ascertain the most
probable range of price movements over the expected investment time
horizon--assessing the individual risk/reward range and the convertible's over-
or undervaluation.

         4. CONVERTIBLE FIT WITHIN OVERALL PORTFOLIO. Finally, we analyze the
convertible's fit within the overall portfolio, reviewing the risk/reward
parameters relative to specific client guidelines, macroeconomic factors and the
impact on the portfolio's industry group and economic sector design.

         WHAT SIGNIFICANT FACTORS IMPACTED THE CALAMOS CONVERTIBLE PORTFOLIO?
         The second quarter of the new millennium proved to be more turbulent
than the already volatile first quarter. On March 24th the NASDAQ hit its peak
intraday trading level of 5078, which was followed by a 40% correction. While it
has now recovered about half of that loss, it still traded at a remarkable 141
times trailing-12-months as of June 30.

         In this environment, CALAMOS ASSET MANAGEMENT has been selective in the
tech sector despite our long-term enthusiasm for its importance to economic
growth. Instead, we chose to own predominantly value-oriented convertibles that
offer defensive characteristics. This stabilizing move enhanced performance.

         At the same time, we reinvested proceeds by increasing the Portfolio's
exposure to the financial sector due to the extremely attractive valuation
levels of the convertibles and their underlying stocks. The overweighting in
this sector along with good bottom-up selection added value. We also added value
by being overweight in utilities as the progressive companies we owned employed
technology to wring out the inefficiencies traditionally associated with that
industry. In addition, we benefited Portfolio performance by increasing the
exposure to consumer-oriented companies; at period-end, pharmaceuticals
comprised the Portfolio's largest industry.

         The Portfolio's energy sector exposure was underweighted. The sharp
price appreciation in oil prices boosted many of the convertible prices in this
sector. We have been underweight in the energy sector since 1997 as a result of
weak global demand and a lack of attractive convertible alternatives in this
sector.

         Finally, we added value by remaining disciplined regarding overall
risk/reward. The deep-in-the-money convertibles performed poorly, but the
Portfolio was minimally exposed to these equity-like issues. The Portfolio was
also positioned in companies with higher credit ratings than the convertible
market as a whole, which proved beneficial.

         WHAT IS THE OUTLOOK FOR THE CALAMOS CONVERTIBLE PORTFOLIO?
         We at CALAMOS ASSET MANAGEMENT acknowledge the bumpy ride investors
have faced. We feel that this volatility--though considerable--will not subside
soon since we are in the midst of a dramatic change in the way businesses
operate. Insightful investors realize that the flip side of volatility is an
opportunistic investment climate.

<PAGE>   6

         We do not feel inflation will spiral out of control. Instead, we
believe productivity increases will continue to offset wage pressure. Today's
increase in inflation is due to short-term supply and demand constraints that
are quickly brought back into equilibrium and, of course, a cartel that is
managing the price of oil. While the financial markets are trying to understand
all of this change, they are also subject to severe mood swings that complicate
matters further.

         At CALAMOS, we are finding excellent opportunities in many of the
old-economy issues that we feel will do well in the new environment. We are also
participating in companies that we feel are laying the foundation or have the
correct business model for the new business environment. We believe the
convertible security as an investment vehicle in these volatile times should
prove a comfortable means to build wealth and navigate this productivity
revolution over the coming decade.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Organization - Calamos Advisors Trust, a Massachusetts business trust organized
February 17, 1999 (the "Trust"), consists of a single series, Calamos
Convertible Portfolio (the "Portfolio"). The Trust currently offers Portfolio's
shares to certain life insurance companies (Participating Insurance Companies)
for allocation to certain separate accounts established for the purpose of
funding qualified and non-qualified variable annuity contracts and variable life
insurance contracts. The Portfolio commenced operations on May 1, 1999.

Portfolio Valuation - Investments are stated at value. Securities for which
quotations are readily available are valued at the last available sales price on
the exchange or market on which they are principally traded, or lacking any
sales, at the mean of the most recently quoted bid and asked prices. Securities
and other assets for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the direction of
the Trust's Board of Trustees.

Investment Transactions and Investment Income - Investment transactions are
recorded on a trade date basis. Realized gains and losses from investment
transactions are recorded on an identified cost basis. Interest income is
recognized using the accrual method and includes amortization of original issue
discount and market discount. Dividend income is recognized on the ex-dividend
date.

Federal Income Taxes - No provision has been made for Federal income taxes since
the Portfolio elected to be taxed as a "regulated investment company" and has
made such distributions to shareholders as to be relieved of all Federal income
taxes.

Capital Loss Carryforwards - As of June 30, 2000, the Portfolio had capital loss
carryforwards of $7,506, which if not used will expire in 2008.

Dividends and Capital Gains - The Portfolio intends to distribute to its
shareholders its net investment income quarterly and net capital gain, if any,
annually. Distributions to shareholders are recorded on ex-dividend date. Income
and capital gain dividends are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles.

Use of Estimates - The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results may differ from those estimates.

NOTE 2 - INVESTMENT ADVISER AND TRANSACTIONS WITH AFFILIATES

Pursuant to an investment advisory agreement with Calamos Asset Management, Inc.
("CAM"), the Portfolio pays an investment advisory fee at the annual rate of
0.75% of the average daily net assets of the Portfolio.

<PAGE>   18

NOTES TO FINANCIAL STATEMENTS (continued)

CAM has voluntarily undertaken to limit normal operating expenses of the
Portfolio to 1.00% of average daily net assets. As of June 30, 2000, this
expense reimbursement and waiver was $52,760. This reimbursement and waiver is
voluntary and may be terminated by CAM at any time.

Certain portfolio transactions for the Funds have been executed through CALAMOS
FINANCIAL SERVICES, INC. ("CFS") as broker, consistent with the Fund's policy of
obtaining best price and execution. During the six months ended June 30, 2000
the Portfolio paid brokerage commissions to CFS on purchases and sales of
portfolio securities in the amount of $269.

Certain officers and trustees of the Trust are also officers and directors of
CAM. All officers and affiliated trustees serve without direct compensation from
the Trust.
