What is the gold (silver) adder and how does it affect the price to plate my gold (silver) part?

All precious metal parts quoted by Advanced Plating Technologies are based upon the current Engelhard Fabricated metal pricing on the day of quote (see above link).  APT does game precious metals quotes by quoting parts at a market gold price well below the current fair market price.

The specific market gold value is listed at the bottom of the quote for reference.  Along with this information the gold or silver adder is provided.  The adder is the amount that the price to plate the part will increase or decrease for every $0.25 change in market silver or $5.00 change in market gold.

Example 1:  Gold Increases

Part 123 is quoted at $1.00/Ea with gold at $1500.00/toz and a $0.01 adder.  If gold increases to $1550.00/toz the cost to process the part will be the quoted price plus 10 adders (there are 10, $5.00 increments or gold adders between $1500 and $1550).  Thus the cost to process the part will be $1.00 + 10 * $0.01 = $1.10 at $1550.00 gold.

Example 2:  Gold Decreases

Part 123 is quoted at $1.00/Ea with gold at $1500.00/toz and a $0.01 adder.  If gold decreases to $1475.00/toz the cost to process the part will be the quoted price minus five adders (there are 5, $5.00 increments or gold adders between $1500 and $1475).  Thus the cost to process the part will be $1.00 – 5 * $0.01 = $0.95 at $1475.00 gold.
