Portfolio Characteristics

Portfolio Characteristics

Equity Beta (3y) Beta is a measure of the tendency of securities to move with the market as a whole. A beta of 1 indicates that the security&#39;s price will move with the market. A beta less than 1 indicates the security tends to be less volatile than the market, while a beta greater than 1 indicates the security is more volatile than the market.<br/><br/>Calculated vs. S&amp;P 500 as of Feb 29, 2020 -0.04
Standard Deviation (3y) Standard deviation measures how dispersed returns are around the average. A higher standard deviation indicates that returns are spread out over a larger range of values and thus, more volatile. as of Feb 29, 2020 2.57%
12m Trailing Yield The yield an investor would have received if they had held the fund over the last twelve months assuming the most recent NAV. The 12-Month yield is calculated by assuming any income distributions over the past twelve months and dividing by the sum of the most recent NAV and any capital gain distributions made over the past twelve months. as of Apr 01, 2020 2.67%
30 Day SEC Yield A standard calculation of yield introduced by the SEC in order to provide fairer comparison among funds. This yield reflects the interest earned after deducting the fund&#39;s expenses during the most recent 30-day period by the average investor in the fund. Negative 30-Day SEC Yield results when accrued expenses of the past 30 days exceed the income collected during the past 30 days. as of Apr 01, 2020 1.93%
Tax Equiv. SEC Yield Tax equivalent yield (TEY) is used by investors to compare yields on taxable and tax-exempt securities after accounting for taxes. TEY represents the yield a taxable bond would have to earn in order to match, after taxes, the yield available on a tax-exempt municipal bond. The highest Federal and State individual income tax rates are assumed.&lt;br&gt;&lt;br&gt;Tax Equivalent Yield (TEY) = Tax Free Municipal Bond Yield/(1 - Tax Rate) as of Apr 01, 2020 3.41%
Weighted Avg Coupon The average coupon rate of the underlying bonds in the fund, weighted by each bond&#39;s face value. as of Apr 01, 2020 4.71%
Effective Duration Effective Duration measures the sensitivity of the price of a bond with or without embedded options to changes in interest rates, taking into account the likelihood of the bond being called, put and/or sunk prior to its final maturity date while incorporating after-tax impacts on the bond. The options-based duration model used by BlackRock employs certain assumptions and may differ from other fund complexes. Effective Duration is measured at the individual bond level, aggregated to the portfolio level, and adjusted for leverage, hedging transactions and non-bond holdings, including derivatives.&lt;br /&gt;As the method for calculating duration in municipal bond funds changed as of Sept. 26, please see the &#39;Literature&#39; section for more information on that measure. as of Apr 01, 2020 6.10 yrs
Weighted Avg Maturity 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 Apr 01, 2020 5.69 yrs
Convexity Convexity measures the change in duration for a given change in rates. Positive convexity indicates that duration lengthens when rates fall and contracts when rates rise; negative convexity indicates that duration contracts when rates fall and increases when rates rise. as of Apr 01, 2020 -0.10
Average Yield to Maturity The discount rate that equates the present value of a bond’s cash flows with its market price (including accrued interest). The Fund Average Yield to Maturity is the weighted average of the fund’s individual bond holding yields based on Net Asset Value (‘NAV’). The measure does not include fees and expenses. For callable bonds, this yield is the yield-to-worst. as of Apr 01, 2020 2.23%
