operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have the ability to meet our liquidity needs for the foreseeable future. As markets change, we continue to monitor our liquidity position. There can be no assurance that the challenging economic environment or a further economic downturn would not impact our ability to obtain financing in the future.

 Selected Measures of Liquidity and Capital Resources

Certain relevant measures of our liquidity and capital resources follow:

In fiscal 2012, we funded our acquisition of Ferrosan’s consumer healthcare business, which closed in December 2011 (which falls in the first fiscal quarter of 2012 for our international operations), with available cash and the proceeds from short-term investments. For additional information on this transaction, see the “Our Business Development Initiatives” section of this Financial Review.

For additional information about the sources and uses of our funds, see the “Analysis of Consolidated Balance Sheets” and “Analysis of Consolidated Statements of Cash Flows” sections of this Financial Review.

Domestic and International Short-Term Funds

Many of our operations are conducted outside the U.S., and significant portions of our cash, cash equivalents and short-term investments are held internationally. We generally hold approximately 10%-30% of these short-term funds in U.S. tax jurisdictions. The amount of funds held in U.S. tax jurisdictions can fluctuate due to the timing of receipts and payments in the ordinary course of business and due to other reasons, such as business-development activities. As part of our ongoing liquidity assessments, we regularly monitor the mix of domestic and international cash flows (both inflows and outflows). Repatriation of overseas funds can result in additional U.S. federal, state and local income tax payments. We record U.S. deferred tax liabilities for certain unremitted earnings, but when amounts earned overseas are expected to be permanently reinvested outside of the U.S., no accrual for U.S. taxes is provided.

Accounts Receivable

We continue to monitor developments regarding government and government agency receivables in several European markets, where economic conditions remain uncertain. Historically, payments from a number of European governments and government agencies extend beyond the contractual terms of sale and the trend is worsening. In Greece, certain of our accounts receivable have been restructured into bonds with maturities that further lengthened the repayment timeline.

We believe that our allowance for doubtful accounts is appropriate. Our assessment is based on an analysis of the following:

(i) payments received to date; (ii) the consistency of payments from customers; (iii) direct and observed interactions with the governments (including court petitions) and with market participants (for example, the factoring industry); and (iv) various third-party assessments of repayment risk (for example, rating agency publications and the movement of rates for credit default swap instruments).
