Table of Contents Mac The following table presents Mac net sales and unit sales information for 2014, 2013 and 2012 (dollars in millions and units in thousands):
## Table 0 ##
The year-over-year growth in Mac net sales and unit sales for 2014 was primarily driven by increased sales of MacBook Air, MacBook Pro and Mac Pro.
Mac net sales and unit sales increased in all of the Company’s operating segments.
Mac ASPs decreased during 2014 compared to 2013 primarily due to price reductions on certain Mac models and a shift in mix towards Mac portable systems.
Mac net sales and unit sales for 2013 were down or relatively flat in all of the Company’s operating segments.
Mac ASPs increased slightly partially offsetting the impact of lower unit sales on net sales.
The decline in Mac unit sales and net sales reflected the overall weakness in the market for personal computers.
iTunes, Software and Services The following table presents net sales information of iTunes, Software and Services for 2014, 2013 and 2012 (dollars in millions):
## Table 1 ##
The increase in net sales of iTunes, Software and Services in 2014 compared to 2013 was primarily due to growth in net sales from the iTunes Store, AppleCare and licensing.
The iTunes Store generated a total of $10.2 billion in net sales during 2014 compared to $9.3 billion during 2013.
Growth in net sales from the iTunes Store was driven by increases in revenue from app sales reflecting continued growth in the installed base of iOS devices and the expanded offerings of iOS Apps and related in-App purchases.
This was partially offset by a decline in sales of digital music.
The increase in net sales of iTunes, Software and Services in 2013 compared to 2012 was primarily due to growth in net sales from the iTunes Store, AppleCare and licensing.
The iTunes Store generated a total of $9.3 billion in net sales during 2013, a 24% increase from 2012.
Growth in the iTunes Store, which includes the App Store, the Mac App Store and the iBooks Store, reflected continued growth in the installed base of iOS devices, expanded offerings of iOS Apps and related in-App purchases, and expanded offerings of iTunes digital content.

KIMCO REALTY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED Noncontrolling interests also includes 138,015 convertible units issued during 2006, by the Company, which are valued at approximately $5.3 million, including a fair market value adjustment of $0.3 million, related to an interest acquired in an office building located in Albany, NY.
These units are redeemable at the option of the holder after one year for cash or at the option of the Company for the Company’s common stock at a ratio of 1:1.
The holder is entitled to a distribution equal to the dividend rate of the Company’s common stock.
The Company is restricted from disposing of these assets, other than through a tax free transaction, until January 2017.
The following table presents the change in the redemption value of the Redeemable noncontrolling interests for the year ended December 31, 2009 and December 31, 2008 (amounts in thousands):
## Table 2 ##

Fair Value Disclosure of Financial Instruments: All financial instruments of the Company are reflected in the accompanying Consolidated Balance Sheets at amounts which, in management’s estimation based upon an interpretation of available market information and valuation methodologies, reasonably approximate their fair values except those listed below, for which fair values are reflected.
The valuation method used to estimate fair value for fixed-rate and variable-rate debt and noncontrolling interests relating to mandatorily redeemable noncontrolling interests associated with finite-lived subsidiaries of the Company is based on discounted cash flow analyses, with assumptions that include credit spreads, loan amounts and debt maturities.
The fair values for marketable securities are based on published or securities dealers’ estimated market values.
Such fair value estimates are not necessarily indicative of the amounts that would be realized upon disposition.
The following are financial instruments for which the Company’s estimate of fair value differs from the carrying amounts (in thousands):
## Table 3 ##
The Company has certain financial instruments that must be measured under the FASB’s Fair Value Measurements and Disclosures guidance, including: available for sale securities, convertible notes and derivatives.
The Company currently does not have non-financial assets and non-financial liabilities that are required to be measured at fair value on a recurring basis.
As a basis for considering market participant assumptions in fair value measurements, the FASB’s Fair Value Measurements and Disclosures guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).
Net interest on the stock loan/borrow business decreased 38% due to decreased rates and balances despite a focus on hard-to-locate securities.
Other interest revenue and expense include earnings on corporate cash and inventory balances, and interest expense on overnight borrowings, our senior notes issued in August, 2009 and the mortgage on our headquarters facility.
Results of Operations - Private Client Group The following table presents consolidated financial information for our PCG segment for the years indicated:
## Table 4 ##
Year ended September 30, 2009 Compared with the Year ended September 30, 2008 - Private Client Group PCG revenues were 22% below the prior year, reflecting the impact of the extremely challenging economic and market conditions.
Commission revenue decreased $269 million, or 18%, from the prior year, with the majority of that decrease experienced by our domestic independent contractor operation.
Commissions in RJ&A PCG declined only $45 million, or 9%, due to the recruitment of 219 employee financial advisors in fiscal 2009 (for a net increase of 94) and 184 in fiscal 2008 (for a net increase of 114).
It generally takes newly recruited financial advisors up to two years to reach their previous production levels.
Average production per employee financial advisor decreased to $417,000 in fiscal 2009, down 19% from the $515,000 attained in fiscal 2008.
The recruitment of above-average producers did not overcome the negative impact that the steep market decline had on our private clients’ investing activities.
RJFS and RJFSA recruited 559 independent contractor financial advisors in fiscal 2009 (for a net increase of 129).
Independent contractor financial advisor average production decreased from $330,000 in fiscal 2008 to $273,000 in fiscal 2009, impacted, like RJ&A, by the challenging economic and market conditions.
