Significant Customers and Concentrations of Credit Risk

Avnet, Inc. (Avnet), one of the Company’s distributors, distributes the Company’s products worldwide. As of September 29, 2012 and March 31, 2012, Avnet accounted for 64% and 67% of the Company’s total net accounts receivable, respectively. Resale of product through Avnet accounted for 44% and 45% of the Company’s worldwide net revenues in the second quarter and the first six months of fiscal 2013, respectively. For the second quarter and the first six months of fiscal 2012, resale of product through Avnet accounted for 47% and 48% of the Company’s worldwide net revenues, respectively. The percentage of accounts receivable due from Avnet and the percentage of worldwide net revenues from Avnet are consistent with historical patterns.

Xilinx is subject to concentrations of credit risk primarily in its trade accounts receivable and investments in debt securities to the extent of the amounts recorded on the consolidated balance sheet. The Company attempts to mitigate the concentration of credit risk in its trade receivables through its credit evaluation process, collection terms, distributor sales to diverse end customers and through geographical dispersion of sales. Xilinx generally does not require collateral for receivables from its end customers or from distributors.

One end customer accounted for 11% and 14% of the Company's worldwide net revenues for the second quarter of fiscal 2013 and 2012, respectively. One end customer accounted for 11% of the Company's worldwide net revenues for the first six months of fiscal 2012. No end customer accounted for more than 10% of the Company's worldwide net revenues for the first six months of fiscal 2013.

The Company mitigates concentrations of credit risk in its investments in debt securities by currently investing more than 89% of its portfolio in AA or higher grade securities as rated by Standard & Poor’s or Moody’s Investors Service. The Company’s methods to arrive at investment decisions are not solely based on the rating agencies’ credit ratings. Xilinx also performs additional credit due diligence and conducts regular portfolio credit reviews, including a review of counterparty credit risk related to the Company’s forward currency exchange contracts. Additionally, Xilinx limits its investments in the debt securities of a single issuer based upon the issuer’s credit rating and attempts to further mitigate credit risk by diversifying risk across geographies and type of issuer.

As of September 29, 2012, approximately 35% of the portfolio consisted of mortgage-backed securities. All of the mortgage-backed securities in the investment portfolio were issued by U.S. government-sponsored enterprises and agencies and are rated AA+ by Standard & Poor’s and AAA by Moody’s Investors Service.

The global credit and capital markets have continued to experience adverse conditions that have negatively impacted the values of various types of investment and non-investment grade securities, and have experienced volatility and disruption due to instability in the global financial system, uncertainty related to global economic conditions and concerns regarding sovereign financial stability. Therefore, there is a risk that the Company may incur other-than-temporary impairment charges for certain types of investments should credit market conditions deteriorate or the underlying assets fail to perform as anticipated.
