The Trust values equity securities at the last reported sale price on the
     
principal exchange or in the principal over-the-counter (“OTC”) market in
     
which such securities are traded, as of the close of regular trading on the New
     
York Stock Exchange (“NYSE”) on the day the securities are being valued or, if
     
there are no sales, at the mean between the last available bid and asked prices
     
on that day. Securities traded on NASDAQ are valued at the NASDAQ Official
     
Closing Price. The Trust values debt securities (including municipal securities,
     
asset-backed securities, collateralized mortgage obligations and term loans)
     
at the last available bid price for such securities or, if such prices are not
     
available, at prices for securities of comparable maturity, quality, and type.
     
Short-term securities with remaining maturities of 60 days or less are valued
     
at amortized cost, which approximates fair value.
         
             
For those securities where quotations or prices are not available, the
     
valuations are determined in accordance with procedures established in good
     
faith by management and approved by the Board of Trustees (“Trustees”). A
     
valuation committee consisting of representatives from investment management,
     
fund administration, legal and compliance is responsible for the oversight of the
     
valuation process of the Trust and convenes monthly, or more frequently as
     
needed. The valuation committee reviews monthly Level 3 fair valued securities
     
methodology, price overrides, broker quoted securities, price source changes,
     
illiquid securities, unchanged valuations, halted securities, price challenges,
     
fair valued securities sold and back testing trade prices in relation to prior day
     
closing prices. On a quarterly basis, the valuations and methodologies of all
     
Level 3 fair valued securities are presented to the Trust’s Trustees.
     
             
Valuations in accordance with these procedures are intended to reflect each
     
security’s (or asset’s) fair value. Such fair value is the amount that the Trust
     
might reasonably expect to receive for the security (or asset) upon its current
     
sale. Each such determination is based on a consideration of all relevant
     
factors, which are likely to vary from one pricing context to another. Examples
     
of such factors may include, but are not limited to: (i) the type of security, (ii)
     
the initial cost of the security, (iii) the existence of any contractual restrictions
     
on the security’s disposition, (iv) the price and extent of public trading in
     
similar securities of the issuer or of comparable companies, (v) quotations or
     
evaluated prices from broker-dealers and/or pricing services, (vi) information
     
obtained from the issuer, analysts, and/or the appropriate stock exchange (for
     
exchange traded securities), (vii) an analysis of the company’s financial
     
statements, and (viii) an evaluation of the forces that influence the issuer and
     
the market(s) in which the security is purchased and sold (e.g. the existence of
     
pending merger activity, public offerings or tender offers that might affect the
     
value of the security).
           
             
For fixed income securities, fair valuations may include input from
     
Guggenheim Partners Investment Management, LLC (“GPIM”) utilizing a
     
wide variety of market data including yields or prices of investments of
     
comparable quality, type of issue, coupon, maturity, rating, indications of
     
value from security dealers, evaluations of anticipated cash flows or
     
collateral, spread over Treasuries, and other information and analysis.
     
GPIM also uses third party service providers to model certain securities
     
using cash flow models to represent a fair market value.
         
             
There are three different categories for valuations. Level 1 valuations are those
     
based upon quoted prices in active markets. Level 2 valuations are those
     
based upon quoted prices in inactive markets or based upon significant
     
observable inputs (e.g. yield curves; benchmark interest rates; indices). Level
     
3 valuations are those based upon unobservable inputs (e.g. discounted cash
     
flow analysis; non-market based methods used to determine fair valuation).
     
             
The Trust values Level 1 securities using readily available market quotations
     
in active markets. Money Market Funds are valued at Net Asset Value. The
     
Trust values Level 2 fixed income securities using independent pricing
     
providers who employ matrix pricing models utilizing market prices, broker
     
quotes and prices of securities with comparable maturities and qualities.
     
The Trust values Level 2 equity securities using independent pricing
     
providers who employ models using various observable market inputs. The
     
fair value estimate for the Level 3 security in the Trust is determined in
     
accordance with the Trust’s valuation procedures described above.
     
             
Transfers between valuation levels, if any, are in comparison to the
     
valuation levels at the end of the previous fiscal year, and are effective as of
     
the beginning of the period.
