Adjustments
to Lehman Brothers Global Family of Indices[i]
As fixed income capital market trends change,
investors’ needs move along with them.
In order to keep pace with investors, debt indices must evolve by
changing the securities that comprise them and the rules by which they are
chosen. After speaking with global
investors and security issuers, Lehman Brothers announced that effective
One of the biggest changes is the liquidity
constraint for the U.S. Aggregate Index.
Effective October 1st, in order to be included in this index,
securities will need to be at least $200 million in size instead of the current
$150 million. Some of the international
Aggregate indices already require their securities to be $300 million and,
according to Lehman Brothers, the U.S. Aggregate Index gradually will as well. This change affects Treasury, agency, credit,
and mortgage-backed securities only.
CMBS and ABS will not be affected, with the former having a criteria of
$500 million initial deal size and $300
million current deal size and the latter requiring that each tranche have $25 million outstanding and be part of a $500
million deal. The liquidity change will
reduce the number of securities in the
The second critical change to the indices is the
introduction of the use of the more conservative between a Moody’s
and S&P rating in determining the rating category in which a security will
be held in the indices. Currently all
split rated securities are carried at their Moody’s
rating. After October 1st
simply the most conservative rating will prevail. Currently 9.6% of the
When the rating change is incorporated with the
liquidity change, the quality breakdown of the U.S. Aggregate Index will be
affected as follows:
Current
Aaa/AAA 74.66% 75.02% +0.36%
A/A 10.54% 11.02% +0.48%
Baa/BBB 9.64% 11.49% +1.85%
The weightings of the individual sectors would
change as well as shown below:

The other changes to the indices will have less
broad impact than the aforementioned.
These include:
·
Capital securities that contain step-up coupon features that move a
security’s coupon payments from fixed to floating will now qualify for index
inclusion and will have a maturity date equal to the step-up date.
·
Taxable municipal bonds will be added back to the U.S. Aggregate
Index. They were removed in the late
1990s due to a decline in issuance, but as origination resumed in 2003 to fund
many
·
Captive finance issuers will now be classified under the parent
company’s classification. For example
Ford Motor Credit and General Motors Acceptance Corp. will be classified in the
Industrial sector under Autos instead of in the Finance sector under Captive
Finance. This change would increase the
Industrial Sector within the Credit Index from 42.85% to 47.90% and decrease
the Financial Institutions Sector from 33.62% to 28.57%.
·
A new sector called Public Organizations Sector is being considered for
inclusion on

With the assistance of modeling support, Lehman Brothers would like to
add Danish MBS to the Global Aggregate and Pan European Aggregate Indices by

GHLC Bonds, which are Japanese mortgage agency obligations, will be
added to the Japanese Aggregate Index.

These changes will allow the indices to better reflect the weightings of the various sectors of the debt capital markets as well as the more conservative market sentiment that is prevalent in today’s financial environment.
