The Fund has adopted fair value accounting standards, which establish an authoritative definition of fair value and set out a hierarchy for measuring fair value. These standards require additional disclosures about the various inputs and valuation techniques used to develop the measurements of fair value, a discussion in changes in valuation techniques and related inputs during the period and expanded disclosure of valuation levels for major security types. These inputs are summarized in the three broad levels listed below:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices included in Level 1. These inputs may include quoted prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates and similar data.

Level 3 – Significant unobservable inputs for the asset or liability, representing the Fund’s view of assumptions a market participant would use in valuing the asset or liability.

Following is a description of the valuation techniques applied to the Fund’s major categories of assets and liabilities measured at fair value on a recurring basis. The Fund’s investments are carried at fair value.

Corporate and Municipal Bonds — Corporate and municipal bonds, including listed issues, are valued at fair value on the basis of valuations furnished by an independent pricing service which utilizes both dealer-supplied valuations and formula-based techniques. The pricing service may consider recently executed transactions in securities of the issuer or comparable issuers, market price quotations (where observable), bond spreads, and fundamental data relating to the issuer. Most municipal bonds are categorized in Level 2 of the fair value hierarchy.

Securities for which market quotations are not readily available, or if the closing price does not represent fair value, are valued following procedures approved by the Board of Directors. The Board of Directors will regularly evaluate whether the Fund’s fair value pricing procedures continue to be appropriate in light of the specific circumstances of the Fund and the quality of prices obtained through the application of such procedures by the Fund’s valuation committee.

When fair value pricing is employed, security prices that the Fund uses to calculate its NAV may differ from quoted or published prices for the same securities. Due to the subjective and variable nature of fair value pricing, it is possible that the fair value determined for a particular security may be materially different (higher or lower) than the price of the security quoted or published by others, the value when trading resumes, and/or the value realized upon the security’s sale. Therefore, if a shareholder purchases or redeems Fund shares when the Fund holds securities priced at a fair value, the number of shares purchased or redeemed may be higher or lower than it would be if the Fund were using market value pricing.

The inputs or methodology used for valuing securities are not an indication of the risk associated with investing in those securities.

The following table is a summary of the inputs used to value the Fund’s securities by level within the fair value hierarchy as of December 31, 2018:

	Level 1		Level 2		Level 3		Total
Corporate Bonds	$	-	$	11,255,000	$	-	$	11,255,000
Municipal Bonds		-		66,200,704		-		66,200,704
Short Term Investments		-		23,105,000		-		23,105,000
Total Investments	$	-	$	100,560,704	$	-	$	100,560,704

Transfers between levels are recognized at the end of the reporting period. During the period ended December 31, 2018, the Fund recognized no transfers between levels.

The Fund did not invest in any Level 3 investments during the period.
