The Trust invests primarily in debt securities issued by municipalities. The ability of the issuers of the debt securities to meet their obligations may be affected by economic developments in a specific industry or municipality. In order to reduce the risk associated with such economic developments, at June 30, 2016, 10.0% of total investments are backed by bond insurance of various financial institutions and financial guaranty assurance agencies. The aggregate percentage insured by an individual financial institution or financial guaranty assurance agency ranged from 0.1% to 5.6% of total investments.
| (1) | Security represents the municipal bond held by a trust that issues residual interest bonds. |
| (2) | Security (or a portion thereof) has been pledged as collateral for residual interest bond transactions. The aggregate value of such collateral is $10,309,689. |
| (3) | Security exempt from registration pursuant to Rule 144A under the Securities Act of 1933, as amended. These securities may be sold in certain transactions in reliance on an exemption from registration (normally to qualified institutional buyers). At June 30, 2016, the aggregate value of these securities is $6,615,578 or 1.9% of the Trust’s net assets. |

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.
| • | Level 1 — quoted prices in active markets for identical investments |
| • | Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.) |
| • | Level 3 — significant unobservable inputs (including a fund’s own assumptions in determining the fair value of investments) |
In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
At June 30, 2016, the hierarchy of inputs used in valuing the Trust’s investments, which are carried at value, were as follows:
| Asset Description | Level 1 | Level 2 | Level 3 | Total | ||||||||||||
| Tax-Exempt Municipal Securities |
$ | — | $ | 383,570,129 | $ | — | $ | 383,570,129 | ||||||||
| Taxable Municipal Securities |
— | 7,881,329 | — | 7,881,329 | ||||||||||||
| Total Investments |
$ | — | $ | 391,451,458 | $ | — | $ | 391,451,458 | ||||||||

The Trust held no investments or other financial instruments as of March 31, 2016 whose fair value was determined using Level 3 inputs. At June 30, 2016, there were no investments transferred between Level 1 and Level 2 during the fiscal year to date then ended.
