BlackRock MuniYield New Jersey Fund, Inc.

Effective December 1, 2007, the BlackRock MuniYield New Jersey Fund, Inc. (the
"Fund") adopted FASB Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"). FAS 157 clarifies the definition of fair value,
establishes a framework for measuring fair values and requires additional
disclosures about the use of fair value measurements.

FAS 157 establishes a hierarchy that classifies these inputs into the three
broad levels listed below:
o     Level 1 - price quotations in active markets/exchanges for identical
      securities
o     Level 2 -other observable inputs (including, but not limited to: quoted
      prices for 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)
o     Level 3 - unobservable inputs based on the best information available in
      the circumstance, to the extent observable inputs are not available
      (including the Fund's own assumptions used in determining the fair value
      of investments)

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

The following table summarizes the inputs used as of February 29, 2008 in
determining the fair valuation of the Fund's investments:
