Calamos Total Return Bond Fund (CTRCX)

Overview

Through its multi-sector fixed income strategy, the fund invests predominantly in U.S. issuers with the goal of generating a high level of both current income and total return that provides consistent excess returns above the benchmark over full market cycles.

Key Features

  • Employs bond-by-bond portfolio construction with a focus on being well compensated for risks taken. We believe a disciplined process, grounded in fundamental research, enables us to achieve higher total returns with less volatility.
  • Draws on a broader investable universe to enhance portfolio construction and risk management. Expanding the universe to include high yield bonds, bank loans and preferreds provides additional opportunities.
  • Utilizes robust, independent credit research. Our fixed income investment process unites quantitative and qualitative analyses into historical and forward-looking models. The result is a credit rating reflective of where a company is heading.
  • Applies a macro overlay to capitalize on misunderstood industries and sectors. The overlay acts as a risk control that also considers the business cycle, geopolitical factors, inflation and real rate expectations.

Portfolio Fit

The fund may be suitable for investors as the cornerstone of a fixed income allocation, with investments diversified across the major sectors of the U.S. bond market. Complementary allocations to specialized fixed income strategies seek to enhance return potential and better manage risk.

Notes

Bond Credit Quality allocation reflects the higher of the ratings of Standards & Poor's Corporation or Moody's Investors Service, Inc. Ratings are relative, subjective and not absolute standards of quality, represent the opinions of the independent, Nationally Recognized Statistical Rating Organizations (NRSRO), and are adjusted to the Standards & Poor's scale shown. Ratings are measured using a scale that typically ranges from AAA (highest) to D (lowest). The security's credit rating does not eliminate risk. The table excludes equity securities, cash and cash equivalents. For more information about securities ratings, please see the Fund's Statement of Additional Information at calamos.com. Additional information on ratings methodologies are available by visiting the NRSRO websites: www.standardandpoors.com and www.moodys.com.

Top Country exposure is measured by country of risk.

Current (SEC) Yield-Reflects the dividends and interest earned by the Fund during the 30-day period ended as of the date stated above after deducting the Fund's expenses for that same period.

Distribution Yield -Is calculated by dividing the sum of all distributions paid by the fund over the trailing 12 months by the fund's NAV as of the date of the period presented. Distributions may include income, short-term capital gains, and long-term capital gains. Short-term and long-term capital gains represent the net trading profits realized over the trailing 12 months in the fund and are not guaranteed. Distribution Yield is based on distributions made in the past and is therefore not reflective of the fund's current portfolio.

Duration- provides a measure of the Fund's interest rate sensitivity-the longer a fund's duration, the more sensitive it is to shifts in interest rates

Option adjusted spread is the yield spread which has to be added to a benchmark yield curve to discount a security's payments to match its market price; uses a dynamic pricing model that accounts for embedded options and is usually measured in basis points.

Turnover-Is the percentage of assets in a portfolio that changed over a certain period, often a year; higher turnover indicates greater buying and selling activity.

Yield-to-worst is the lowest potential yield that can be received on a bond without the issuer defaulting.
