technologies and a global leader in biosimilars, for $90 per share in cash, for a total enterprise value of approximately $17 billion. We expect to finance the transaction through a combination of existing cash and new debt, with approximately two-thirds of the value financed from cash and one-third from debt.

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 up to $10 billion of our 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 indefinitely reinvested outside 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 challenging and uncertain. Historically, payments from a number of these European governments and government agencies extend beyond the contractual terms of sale. There have been some improvements in the amount of outstanding accounts receivable balances in excess of one year.

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).

As of December 31, 2014, we had about $814 million in aggregate gross accounts receivable from governments and/or government agencies in Italy, Spain, Portugal and Greece where economic conditions remain challenging and uncertain. Such receivables in excess of one year from the invoice date, totaling $96 million, were as follows: $36 million in Italy; $25 million in Spain; $24 million in Portugal; and $11 million in Greece.

Although certain European governments and government agencies sometimes delay payments beyond the contractual terms of sale, we seek to appropriately balance repayment risk with the desire to maintain good relationships with our customers and to ensure a humanitarian approach to local patient needs.

We will continue to closely monitor repayment risk and, when necessary, we will continue to adjust our
