Western Asset Active Bond Aggregate Portfolios

Investment Overview

The Western Asset Active Bond Aggregate Portfolios invest in securities within the Bloomberg Barclays U.S. Aggregate Bond Index, including: primarily governments, corporates and mortgages, and asset-backed securities, to seek to maximize total returns.


Investment Philosophy


  • Seek out the greatest long-term value by thoroughly analyzing a wide range of sectors of the fixed income market.


  • We seek to identify and favor sectors and issuers that are undervalued or out of favor in the market.

Diversified strategies

  • Results do not depend on only one or two opportunities; multiple themes are employed in portfolios. Diversification seeks to limit the impact of a single adverse market event.
  • Strive to add incremental value over time and potentially reduce volatility.

Sector rotation

  • The Active Bond Aggregate Portfolios predominantly focus on investment-grade securities similar to those represented within the Bloomberg Barclays U.S. Aggregate Bond Index.

Key Differentiators

Leverage Western Asset Management resources

  • Institutional-caliber buying power and trading expertise 
  • Access to proprietary credit research team 
  • Exclusive focus on fixed income management 

Ability to customize the portfolio to meet client constraints


Diversification does not guarantee a profit or protect against a loss.

There is no guarantee that the Portfolio's objectives will be met.




Interest rate exposure/duration weighting

Western’s investment team comprehensively analyzes a variety of domestic and international macroeconomic factors to establish a duration target.

Term structure weighting

The Firm carefully employs strategies in an attempt to take advantage of changes in the yield curve’s shape and shifts in the relationship between short-, intermediate- and long-maturity securities.

Sector allocation

Western Asset believes that value can be added to a portfolio by actively rotating among, and within, different sectors of the bond market. The investment team studies the fundamental factors that influence sector spread relationships.

Issue selection

Using a bottom-up process, the Firm seeks to identify companies with changing credit characteristics and securities that are undervalued and out of favor due to unusual circumstances.

The investment process may change over time. The characteristics set forth above are intended as a general illustration of some of the criteria the strategy team considers in selecting securities for client portfolios. There is no guarantee investment objectives will be achieved.

What I Should Know
Before Investing

All investments involve risk, including loss of principal and there is no guarantee that investment objectives will be met.  Fixed income securities may be subject to extension risk, which is the risk that the issuer will repay their obligations more slowly than the market anticipates in the event market interest rates rise. Issuers also have the right to pay their payment obligations ahead of schedule in the event market interest rates fall, subjecting to prepayment risk.  Fixed income securities are subject to interest rate and credit risk, which is a possibility that the issuer of a security will be unable to make interest payments and repay the principal on its debt. As interest rates rise, the price of fixed income securities falls.  Foreign securities, where permitted, are subject to the additional risks of fluctuations in foreign exchange rates, changes in political and economic conditions, foreign taxation, and differences in auditing and financial standards. These risks are magnified in the case of investments in emerging markets.  U.S. Treasuries are direct debt obligations issued and backed by the "full faith and credit" of the U.S. government. The U.S. government guarantees the principal and interest payments on U.S. Treasuries when the securities are held to maturity. Unlike U.S. Treasury securities, debt securities issued by the federal agencies and instrumentalities and related investments may or may not be backed by the full faith and credit of the U.S. government.  Even when the U.S. government guarantees principal and interest payments on securities, this guarantee does not apply to losses resulting from declines in the market value of these securities.  Investments may also be made in mortgage-backed, asset-backed securities and taxable municipal securities. Asset-backed securities generally decrease in value as a result of interest rate increases, but may benefit less than other fixed-income securities from declining interest rates, principally because of prepayments. Mortgage-backed securities involve additional risk over more traditional fixed-income investments, including: interest rate risk, implied call and extension risks; and the possibility of premature return of principal due to mortgage prepayment, which can reduce expected yield and lead to price volatility. 

A general rise in interest rates may lead to increased portfolio volatility.

Verification assesses whether (1) the firm has complied with all the composite construction requirements of the GIPS standards on a firm-wide basis and (2) the firm’s policies and procedures are designed to calculate and present performance in compliance with the GIPS standards. The verification does not ensure the accuracy of any specific composite presentation.

For GIPS® purposes, the Firm is defined as Western Asset, a primarily fixed-income investment manager comprised of Western Asset Management Company, LLC; Western Asset Management Company Limited, authorised and regulated by the Financial Conduct Authority ("FCA"); Western Asset Management Company Pte.

Each Western Asset company is a wholly owned subsidiary of Legg Mason, Inc. ("Legg Mason") but operates autonomously, and Western Asset, as a Firm, is held out to the public as a separate entity.

The Firm is comprised of several entities as a result of various historical acquisitions made by Western Asset and their respective performance has been integrated into the Firm in line with the portability requirements set forth by GIPS.

Western Asset – Active Bond Aggregate portfolios are discretionary fixed-income portfolios that offer – to individual and taxable institutional investors – tailored bond management that utilizes sector rotation between the major areas of the U.S. taxable fixed-income markets (governments, corporates, and mortgage- and asset-backed securities), along with limited-duration bets around the benchmark to seek to maximize total returns. The composite is comprised of accounts that are separately managed accounts (SMAs), managed in accordance with the strategy with an account minimum of US $800,000. The composite employs a 10% significant cash flow policy. The composite was created on January 1, 2006.

Effective January 1, 2013, the number of portfolios reflects a change from prior periods due to an aggregation of accounts as reported by one sponsor. For periods prior to 2013, the firm excluded accounts designated by the sponsor as client-restricted.

For comparison purposes, composite returns are shown against returns of the Bloomberg Barclays U.S. Aggregate Bond Index. An investor cannot invest directly in an index.

1“Pure” gross returns are presented as supplemental information to the net returns. The current fee schedule is 1.50% on all assets. Net returns are calculated by deducting the anticipated maximum annual bundled fee applied on a monthly basis from the "pure" gross monthly return. The bundled fee includes all charges for trading costs, portfolio management, custody, and other administrative fees. Bundled fees may vary across different financial firms and across different accounts based upon account size and other factors. Returns and market values are expressed in USD.

Dispersion is calculated using the asset-weighted standard deviation of annual returns of those portfolios that were included in the composite for the entire year (equal-weighted prior to 2014). Periods with five or fewer accounts are not statistically representative and are not presented. The three-year annualized ex-post standard deviation measures the variability of the composite and the benchmark returns over the preceding 36-month period. Standard deviation is not presented for periods where 36 monthly returns are not available for the composite or the benchmark.

Past investment results are not indicative of future investment results. Information contained herein is believed to be accurate, but cannot be guaranteed. Employees and/or clients of Western Asset may have a position in the securities mentioned.
