% of Market Value

Type Fund
Geographic exposure relates principally to the domicile of the issuers of the securities held in the product, added together and then expressed as a percentage of the product’s total holdings. However, in some instances it can reflect the country where the issuer of the securities carries out much of their business.

Type Fund
as of 22-Aug-2019

% of Market Value

Type Fund
The maturity breakdown above is based on Weighted Average Life (WAL). WAL is the average length of time to the repayment of principal for the securities in the fund. This metric considers the likelihood that bonds will be called or prepaid before the scheduled maturity date.

as of 22-Aug-2019

% of Market Value

Type Fund
Credit quality ratings on underlying securities of the fund are received from S&P, Moody’s and Fitch and converted to the equivalent S&P major rating category. This breakdown is provided by BlackRock and takes the median rating of the three agencies when all three agencies rate a security the lower of the two ratings if only two agencies rate a security and one rating if that is all that is provided. Unrated securities do not necessarily indicate low quality. Below investment-grade is represented by a rating of BB and below. Ratings and portfolio credit quality may change over time.
Allocations are subject to change.
