1. Significant Accounting Policies

The following accounting policies are in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and are consistently followed by Delaware Investments National Municipal Income Fund (Fund). This report covers the period of time since the Fund’s last fiscal year end.

Security Valuation — Debt securities are valued based upon valuations provided by an independent pricing service or broker and reviewed by management. To the extent current market prices are not available, the pricing service may take into account developments related to the specific security, as well as transactions in comparable securities. Valuations for fixed income securities utilize matrix systems, which reflect such factors as security prices, yields, maturities, and ratings, and are supplemented by dealer and exchange quotations. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of the Fund’s Board of Trustees (Board). In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security.

2. Investments

U.S. GAAP defines fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. A three-level hierarchy for fair value measurements has been established based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. The Fund’s investment in its entirety is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-level hierarchy of inputs is summarized below.

Level 1 – 

Inputs are quoted prices in active markets for identical investments. (Examples: equity securities, open-end investment companies, futures contracts, exchange-traded options contracts)

 
Level 2 –

Other observable inputs, including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs. (Examples: debt securities, government securities, swap contracts, foreign currency exchange contracts, foreign securities utilizing international fair value pricing, broker-quoted securities, fair valued securities)

 
Level 3 –

Significant unobservable inputs, including the Fund’s own assumptions used to determine the fair value of investments. (Examples: broker-quoted securities, fair valued securities)

Level 3 investments are valued using significant unobservable inputs. The Fund may also use an income-based valuation approach in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Valuations may also be based upon current market prices of securities that are comparable in coupon, rating, maturity, and industry. The derived value of a Level 3 investment may not represent the value which is received upon disposition and this could impact the results of operations.

The following table summarizes the valuation of the Fund’s investments by fair value hierarchy levels as of Dec. 31, 2014:

  Level 2
Municipal Bonds $ 95,408,508

During the year ended Dec. 31, 2014, there were no transfers between Level 1 investments, Level 2 investments, or Level 3 investments that had a material impact to the Fund. The Fund’s policy is to recognize transfers between levels at the beginning of the reporting period.
