software and will give the Company a comprehensive design-to-silicon flow that links directly into the semiconductor manufacturing process.
Integrating HPL’s yield management and test chip technologies into the Company’s industry-leading DFM portfolio is also expected to enable customers to increase their productivity and improve profitability in the design and manufacture of advanced semiconductor devices.
Purchase Price.
The Company paid $11.0 million in cash for all outstanding shares of HPL.
In addition, the Company had a prior investment in HPL of approximately $1.9 million.
The total purchase consideration consisted of: (in thousands)
## Table 0 ##
Acquisition-related costs of $2.8 million consist primarily of legal, tax and accounting fees of $1.6 million, $0.3 million of estimated facilities closure costs and other directly related charges, and $0.9 million in employee termination costs.
As of October 31, 2006, the Company had paid $2.2 million of the acquisition related costs, of which $1.1 million were for professional services costs, $0.2 million were for facilities closure costs and $0.9 million were for employee termination costs.
The $0.6 million balance remaining at October 31, 2006 consists of professional and tax-related service fees and facilities closure costs.
Assets Acquired.
The Company acquired $8.5 million of intangible assets consisting of $5.1 million in core developed technology, $3.2 million in customer relationships and $0.2 million in backlog to be amortized over two to four years.
Approximately $0.8 million of the purchase price represents the fair value of acquired in-process research and development projects that have not yet reached technological feasibility and have no alternative future use.
Accordingly, the amount was immediately expensed and included in the Company’s condensed consolidated statement of operations for the first quarter of fiscal year 2006.
Additionally, the Company acquired tangible assets of $14.0 million and assumed liabilities of $10.9 million.
Goodwill, representing the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in the merger was $3.4 million.
Goodwill resulted primarily from the Company’s expectation of synergies from the integration of HPL’s technology with the Company’s technology and operations.
Other.
During the fiscal year 2006, the Company completed an asset acquisition for cash consideration of $1.5 million.
This acquisition is not considered material to the Company’s consolidated balance sheet and results of operations.
Fiscal 2005 Acquisitions Nassda Corporation (Nassda) The Company acquired Nassda on May 11, 2005.
Reasons for the Acquisition.
The Company believes Nassda’s full-chip circuit simulation and analysis software will broaden its offerings of transistor-level circuit simulation tools, particularly in the area of mixed-signal and memory design.
Purchase Price.
The Company acquired all the outstanding shares of Nassda for total cash consideration of $200.2 million, or $7.00 per share.
In addition, as required by the merger agreement, certain Nassda officers, directors and employees who were defendants in certain preexisting litigation

Foreign Currency Risk.
We operate internationally and are exposed to potentially adverse movements in currency exchange rates.
The functional currency of the majority of our active foreign subsidiaries is the foreign subsidiary’s local currency.
We enter into hedges in the form of foreign currency forward contracts to reduce our exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions including: (1) certain assets and liabilities, (2) shipments forecasted to occur within approximately one month, (3) future billings and revenue on previously shipped orders, and (4) certain future intercompany invoices denominated in foreign currencies.
The foreign currency contracts are carried at fair value and denominated in various currencies as listed in the tables below.
The duration of forward contracts usually ranges from one month to 21 months.
A description of our accounting for foreign currency contracts is included in Note 2 and Note 5 of Notes to Consolidated Financial Statements.
The success of our hedging activities depends upon the accuracy of our estimates of various balances and transactions denominated in non-functional currencies.
To the extent our estimates are correct, gains and losses on our foreign currency contracts will be offset by corresponding losses and gains on the underlying transactions.
For example, if the Euro were to depreciate by 10% compared to the U. S.  dollar prior to the settlement of the Euro forward contracts listed in the table below providing information as of October 31, 2018, the fair value of the contracts would decrease by approximately $12.4 million, and we would be required to pay approximately $12.4 million to the counterparty upon contract maturity.
At the same time, the U. S.  dollar value of our Euro-based expenses would decline, resulting in a gain and positive cash flow of approximately $12.4 million that would offset the loss and negative cash flow on the maturing forward contracts.
Net unrealized loss of approximately $23.9 million and gain of $4.4 million, net of tax, are included in accumulated other comprehensive income (loss) in our consolidated balance sheets as of October 31, 2018 and 2017, respectively.
If estimates of our balances and transactions prove inaccurate, we will not be completely hedged, and we will record a gain or loss, depending upon the nature and extent of such inaccuracy.
We do not use foreign currency forward contracts for speculative or trading purposes.
We enter into foreign exchange forward contracts with financial institutions and have not experienced nonperformance by counterparties.
Further, we anticipate performance by all counterparties to such agreements.
