NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
NOTE A – BASIS OF PRESENTATION
The accompanying unaudited condensed consolidated financial statements of Boston Scientific Corporation have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for fair presentation have been included. Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. For further information, refer to the consolidated financial statements and footnotes thereto included in Item 8 of our most recent Annual Report on Form 10-K.
We evaluate events occurring after the date of our most recent accompanying unaudited condensed consolidated balance sheets for potential recognition or disclosure in our financial statements. We did not identify any material subsequent events requiring adjustment to our accompanying unaudited condensed consolidated financial statements (recognized subsequent events) for the three months ended March 31, 2016. Those items requiring disclosure (unrecognized subsequent events) in the financial statements have been disclosed accordingly. Refer to Note I - Commitments and Contingencies for more information.
Pension Termination Charges
Following our 2006 acquisition of Guidant Corporation, we sponsored the Guidant Retirement Plan, a frozen noncontributory defined benefit plan covering a select group of current and former employees. The plan was partially frozen as of September 25, 1995 and completely frozen as of May 31, 2007. The plan was subsequently terminated effective December 1, 2014. During 2015, we finalized the termination process and settled the plan’s obligations, and as a result, we recorded pension termination charges of $8 million during the first quarter of 2015 and an additional $36 million during the third quarter of 2015 for a total of $44 million of pension termination charges in the year ended December 31, 2015. We do not expect to record any additional pension termination charges in 2016 related to the termination of the Guidant Retirement Plan.
NOTE B – ACQUISITIONS AND STRATEGIC INVESTMENTS
We did not close any material acquisitions during the first quarter of 2016 and 2015.
Certain of our acquisitions involve contingent consideration arrangements. Payment of additional consideration is generally contingent on the acquired company reaching certain performance milestones, including attaining specified revenue levels, achieving product development targets and/or obtaining regulatory approvals. In accordance with U.S. GAAP, we recognize a liability equal to the fair value of the contingent payments we expect to make as of the acquisition date. We re-measure this liability each reporting period and record changes in the fair value through a separate line item within our condensed consolidated statements of operations.
We recorded net expenses related to the changes in fair value of our contingent consideration liabilities of $4 million and $27 million during the first quarter of 2016 and the first quarter of 2015, respectively. We paid contingent consideration of $63 million during the first quarter of 2016 and $99 million during the first quarter of 2015.
Changes in the fair value of our contingent consideration liabilities were as follows (in millions):
As of March 31, 2016, the maximum amount of future contingent consideration (undiscounted) that we could be required to pay was approximately $1.586 billion.
Contingent consideration liabilities are remeasured to fair value each reporting period using projected revenues, discount rates, probabilities of payment and projected payment dates. The recurring Level 3 fair value measurements of our contingent consideration liabilities include the following significant unobservable inputs:
Increases or decreases in the fair value of our contingent consideration liabilities can result from changes in discount periods and rates, as well as changes in the timing and amount of revenue estimates or in the timing or likelihood of achieving R&D, regulatory commercialization-based and revenue-based milestones. Projected contingent payment amounts related to certain R&D, regulatory and commercialization-based and certain revenue-based milestones are discounted back to the current period using a discounted cash flow (DCF) model. Other revenue-based payments are valued using a Monte Carlo valuation model, which simulates future revenues during the earn-out period using management's best estimates. Projected revenues are based on our most recent internal operational budgets and long-range strategic plans. Increases in projected revenues and probabilities of payment may result in higher fair value measurements. Increases in discount rates and the time to payment may result in lower fair value measurements. Increases or decreases in any of those inputs together, or in isolation, may result in a significantly lower or higher fair value measurement.
We did not close any material strategic investments during the first quarter of 2016 and 2015.
We account for certain of our strategic investments, as equity method investments, in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 323, Investments - Equity Method and Joint Ventures. The book value of investments that we accounted for under the equity method of accounting was $184 million as of March 31, 2016 and $173 million as of December 31, 2015. The aggregate value of our cost method investments was $46 million as of March 31, 2016 and $45 million as of December 31, 2015. In addition we had notes receivable from certain companies that we account for under the cost method of $32 million as of March 31, 2016 and $30 million as of December 31, 2015.
As of March 31, 2016, the book value of our equity method investments exceeded our share of the book value of the investees’ underlying net assets by approximately $100 million, which represents amortizable intangible assets and in-process research and development, corresponding deferred tax liabilities, and goodwill. During the three months ended March 31, 2016 and March 31, 2015, the net losses from our equity method adjustments, presented within the Other, net caption of our condensed consolidated statement of operations, were immaterial.
NOTE C – GOODWILL AND OTHER INTANGIBLE ASSETS
The gross carrying amount of goodwill and other intangible assets and the related accumulated amortization for intangible assets subject to amortization and accumulated write-offs of goodwill as of March 31, 2016 and December 31, 2015 are as follows:
Our technology-related intangible assets that are not subject to amortization represent technical processes, intellectual property and/or institutional understanding acquired through business combinations that are fundamental to the on-going operations of our business and have no limit to their useful life. Our technology-related intangible assets that are not subject to amortization are comprised primarily of certain acquired balloon and other technology, which is foundational to our continuing operations within the Cardiovascular market and other markets within interventional medicine. We assess our indefinite-lived intangible assets at least annually for impairment and reassess their classification as indefinite-lived assets. We assess qualitative factors to determine whether the existence of events and circumstances indicate that it is more likely than not that our indefinite-lived intangible assets are impaired. If we conclude that it is more likely than not that the asset is impaired, we then determine the fair value of the intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying value in accordance with ASC Topic 350, Intangibles - Goodwill and Other.
The following represents our goodwill balance by global reportable segment:
Goodwill Impairment Testing
We test our goodwill balances during the second quarter of each year for impairment, or more frequently if indicators are present or changes in circumstances suggest that an impairment may exist. Refer to Note D - Goodwill and Other Intangible Assets contained in Item 8 of our most recent Annual Report filed on Form 10-K for discussion of our most recent goodwill impairment test.
The following is a rollforward of accumulated goodwill write-offs by global reportable segment:
Intangible Asset Impairment Testing
On a quarterly basis, we monitor for events or other potential indicators of impairment that would warrant an interim impairment test of our intangible assets. We did not record any intangible asset impairment charges during the three months ended March 31, 2016 and March 31, 2015.
NOTE D – FAIR VALUE MEASUREMENTS
Derivative Instruments and Hedging Activities
We address market risk from changes in foreign currency exchange rates and interest rates through a risk management program that includes the use of derivative financial instruments, and we operate the program pursuant to documented corporate risk management policies. Our derivative instruments do not subject our earnings or cash flows to material risk, as gains and losses on these derivatives generally offset losses and gains on the item being hedged. We do not enter into derivative transactions for speculative purposes, and we do not have any non-derivative instruments that are designated as hedging instruments pursuant to FASB ASC Topic 815, Derivatives and Hedging (Topic 815).
We are exposed to currency risk consisting primarily of foreign currency denominated monetary assets and liabilities, forecasted foreign currency denominated intercompany and third-party transactions and net investments in certain subsidiaries. We manage our exposure to changes in foreign currency exchange rates on a consolidated basis to take advantage of offsetting transactions. We use derivative instruments, and non-derivative transactions to reduce the risk that our earnings and cash flows associated with these foreign currency denominated balances and transactions will be adversely affected by foreign currency exchange rate changes.
Currently or Previously Designated Foreign Currency Hedges
All of our designated currency hedge contracts outstanding as of March 31, 2016 and December 31, 2015 were cash flow hedges under Topic 815 intended to protect the U.S. dollar value of our forecasted foreign currency denominated transactions. We record the effective portion of any change in the fair value of foreign currency cash flow hedges in other comprehensive income (OCI) until the related third-party transaction occurs. Once the related third-party transaction occurs, we reclassify the effective portion of any related gain or loss on the foreign currency cash flow hedge to earnings. In the event the hedged forecasted transaction does not occur, or it becomes no longer probable that it will occur, we reclassify the amount of any gain or loss on the related cash flow hedge to earnings at that time. We had currency derivative instruments designated as cash flow hedges outstanding in the contract amount of $2.197 billion as of March 31, 2016 and $1.458 billion as of December 31, 2015.
We recognized net gains of $48 million in earnings on our cash flow hedges during the first quarter of 2016, as compared to net gains of $49 million during the first quarter of 2015. All currency cash flow hedges outstanding as of March 31, 2016 mature within 36 months. As of March 31, 2016, $77 million of net gains, net of tax, were recorded in accumulated other comprehensive income (AOCI) to recognize the effective portion of the fair value of any currency derivative instruments that are, or previously were, designated as foreign currency cash flow hedges, as compared to net gains, net of tax, of $145 million as of December 31, 2015. As of March 31, 2016, $70 million of net gains, net of tax, may be reclassified to earnings within the next twelve months.
The success of our hedging program depends, in part, on forecasts of transaction activity in various currencies (primarily Japanese yen, British pound sterling, Australian dollar and Canadian dollar). We may experience unanticipated currency exchange gains or losses to the extent that there are differences between forecasted and actual activity during periods of currency volatility. In addition, changes in foreign currency exchange rates related to any unhedged transactions may impact our earnings and cash flows.
Non-designated Foreign Currency Contracts
We use currency forward contracts as a part of our strategy to manage exposure related to foreign currency denominated monetary assets and liabilities. These currency forward contracts are not designated as cash flow, fair value or net investment hedges under Topic 815; are marked-to-market with changes in fair value recorded to earnings; and are entered into for periods consistent with currency transaction exposures, generally less than one year. We had currency derivative instruments not designated as hedges under Topic 815 outstanding in the contract amount of $2.257 billion as of March 31, 2016 and $2.090 billion as of December 31, 2015.
Interest Rate Hedging
Our interest rate risk relates primarily to U.S. dollar borrowings, partially offset by U.S. dollar cash investments. We have historically used interest rate derivative instruments to manage our earnings and cash flow exposure to changes in interest rates by converting floating-rate debt into fixed-rate debt or fixed-rate debt into floating-rate debt.
We designate these derivative instruments either as fair value or cash flow hedges under Topic 815. We record changes in the value of fair value hedges in interest expense, which is generally offset by changes in the fair value of the hedged debt obligation. Interest payments made or received related to our interest rate derivative instruments are included in interest expense. We record the effective portion of any change in the fair value of derivative instruments designated as cash flow hedges as unrealized gains or losses in OCI, net of tax, until the hedged cash flow occurs, at which point the effective portion of any gain or loss is reclassified to earnings. We record the ineffective portion of our cash flow hedges in interest expense. In the event the hedged cash flow does not occur, or it becomes no longer probable that it will occur, we reclassify the amount of any gain or loss on the related cash flow hedge to interest expense at that time.
In the fourth quarter of 2013, we entered into interest rate derivative contracts having a notional amount of $450 million to convert fixed-rate debt into floating-rate debt, which we designated as fair value hedges. During the first quarter of 2015, we terminated these hedges, and we received total proceeds of approximately $35 million, which included approximately $7 million of net accrued interest receivable. We assessed at inception, and re-assessed on an ongoing basis, whether the interest rate derivative contracts were highly effective in offsetting changes in the fair value of the hedged fixed-rate debt. During the first quarter of 2015, we recognized, in interest expense, an $8 million loss on our hedged debt and an $8 million gain on the related interest rate derivative contract.
We are amortizing the gains and losses on previously terminated interest rate derivative instruments, including fixed-to-floating interest rate contracts designated as fair value hedges, and forward starting interest rate derivative contracts and treasury locks designated as cash flow hedges upon termination into earnings as a component of interest expense over the remaining term of the hedged debt, in accordance with Topic 815. The carrying amount of certain of our senior notes included unamortized gains of $60 million as of March 31, 2016 and $63 million as of December 31, 2015, and unamortized losses of $1 million as of March 31, 2016 and $1 million as of December 31, 2015 related to the fixed-to-floating interest rate contracts. In addition, we had pre-tax net gains within AOCI related to terminated forward starting interest rate derivative contracts and treasury locks of $10 million as of March 31, 2016 and $10 million as of December 31, 2015. The net gains that we recognized as a reduction of interest expense in earnings related to previously terminated interest rate derivatives were approximately $3 million during the first quarter of 2016 and $2 million during the first quarter of 2015. As of March 31, 2016, $13 million of pre-tax net gains may be reclassified to earnings within the next twelve months as a reduction to interest expense from amortization of our terminated interest rate derivative contracts.
Counterparty Credit Risk
We do not have significant concentrations of credit risk arising from our derivative financial instruments, whether from an individual counterparty or a related group of counterparties. We manage the concentration of counterparty credit risk on our derivative instruments by limiting acceptable counterparties to a diversified group of major financial institutions with investment grade credit ratings, limiting the amount of credit exposure to each counterparty, and actively monitoring their credit ratings and outstanding fair values on an ongoing basis. Furthermore, none of our derivative transactions are subject to collateral or other security arrangements, and none contain provisions that are dependent on our credit ratings from any credit rating agency.
We also employ master netting arrangements that reduce our counterparty payment settlement risk on any given maturity date to the net amount of any receipts or payments due between us and the counterparty financial institution. Thus, the maximum loss due to counterparty credit risk is limited to the unrealized gains in such contracts net of any unrealized losses should any of these counterparties fail to perform as contracted. Although these protections do not eliminate concentrations of credit risk, as a result of the above considerations, we do not consider the risk of counterparty default to be significant.
Fair Value of Derivative Instruments
The following presents the effect of our derivative instruments designated as cash flow hedges under Topic 815 on our accompanying unaudited condensed consolidated statements of operations during the first quarter of 2016 and 2015 (in millions):
The amount of gain (loss) recognized in earnings related to the ineffective portion of hedging relationships was immaterial for all periods presented.
Net gains and losses on currency hedge contracts not designated as hedging instruments were offset by net losses and gains from foreign currency transaction exposures, as shown in the following table:
Topic 815 requires all derivative instruments to be recognized at their fair values as either assets or liabilities on the balance sheet. We determine the fair value of our derivative instruments using the framework prescribed by FASB ASC Topic 820, Fair Value Measurements and Disclosures (Topic 820), by considering the estimated amount we would receive or pay to transfer these instruments at the reporting date and by taking into account current interest rates, foreign currency exchange rates, the creditworthiness of the counterparty for the assets and our creditworthiness for liabilities. In certain instances, we may utilize financial models to measure fair value. In doing so, we use inputs that include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; other observable inputs for the asset or liability; and inputs derived principally from, or corroborated by, observable market data by correlation or other means. As of March 31, 2016, we have classified all of our derivative assets and liabilities within Level 2 of the fair value hierarchy prescribed by Topic 820, as discussed below, because these observable inputs are available for substantially the full term of our derivative instruments.
The following are the balances of our derivative assets and liabilities as of March 31, 2016 and December 31, 2015:
Other Fair Value Measurements
Recurring Fair Value Measurements
On a recurring basis, we measure certain financial assets and financial liabilities at fair value based upon quoted market prices, where available. Where quoted market prices or other observable inputs are not available, we apply valuation techniques to estimate fair value. Topic 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value. The three levels of the hierarchy are defined as follows:
Assets and liabilities measured at fair value on a recurring basis consist of the following as of March 31, 2016 and December 31, 2015:
Our investments in money market and government funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. These investments are classified as cash and cash equivalents within our accompanying unaudited condensed consolidated balance sheets, in accordance with U.S. GAAP and our accounting policies. In addition to $91 million invested in money market and government funds as of March 31, 2016, we had $15 million in short-term time deposits and $232 million in interest bearing and non-interest bearing bank accounts. In addition to $118 million invested in money market and government funds as of December 31, 2015, we had $31 million in short-term deposits and $170 million in interest bearing and non-interest bearing bank accounts.
Our recurring fair value measurements using significant unobservable inputs (Level 3) relate solely to our contingent consideration liabilities. Refer to Note B - Acquisitions and Strategic Investments for a discussion of the changes in the fair value of our contingent consideration liabilities.
Non-Recurring Fair Value Measurements
We hold certain assets and liabilities that are measured at fair value on a non-recurring basis in periods subsequent to initial recognition. The fair value of a cost method investment is not estimated if there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment. Refer to Note B – Acquisitions and Strategic Investments for a discussion of our cost method investments.
The fair value of our outstanding debt obligations was $6.037 billion as of March 31, 2016 and $5.887 billion as of December 31, 2015, which was determined by using primarily quoted market prices for our publicly registered senior notes, classified as Level 1 within the fair value hierarchy. Refer to Note E – Borrowings and Credit Arrangements for a discussion of our debt obligations.
NOTE E – BORROWINGS AND CREDIT ARRANGEMENTS
We had total debt of $5.677 billion as of March 31, 2016 and December 31, 2015. The debt maturity schedule for the significant components of our debt obligations as of March 31, 2016 is as follows:
Revolving Credit Facility
On April 10, 2015, we entered into a new $2.000 billion revolving credit facility (the 2015 Facility) with a global syndicate of commercial banks and terminated our previous $2.000 billion revolving credit facility. The 2015 Facility matures on April 10, 2020. Eurodollar and multicurrency loans under the 2015 Facility bear interest at LIBOR plus an interest margin of between 0.900 percent and 1.500 percent, based on our corporate credit ratings and consolidated leverage ratio (1.300 percent as of March 31, 2016). In addition, we are required to pay a facility fee based on our credit ratings, consolidated leverage ratio and the total amount of revolving credit commitment, regardless of usage, under the credit agreement (0.200 percent per year as of March 31, 2016). The 2015 Facility contains covenants which, among other things, require that we maintain a minimum interest coverage ratio of 3.0 times consolidated EBITDA and a maximum leverage ratio of 4.5 times consolidated EBITDA for the first four fiscal quarter-ends following the closing of the AMS Portfolio Acquisition on August 3, 2015, and decreasing to 4.25 times, 4.0 times, and 3.75 times consolidated EBITDA for the next three fiscal quarter-ends after such four fiscal quarter-ends, respectively, and then to 3.50 times for each fiscal quarter-end thereafter. There were no amounts borrowed under our current and prior revolving credit facilities as of March 31, 2016 or December 31, 2015.
The credit agreement for the 2015 Facility provides for an exclusion from the calculation of consolidated EBITDA, as defined by the credit agreement, through the credit agreement maturity, of any non-cash charges and up to $620 million in restructuring charges and restructuring-related expenses related to our current or future restructuring plans. As of March 31, 2016, we had $547 million of the restructuring charge exclusion remaining. In addition, any cash litigation payments (net of any cash litigation receipts), as defined by the agreement, are excluded from the calculation of consolidated EBITDA and any new debt issued to fund any tax deficiency payments is excluded from consolidated total debt, as defined in the agreement, provided that the sum of any excluded net cash litigation payments and any new debt issued to fund any tax deficiency payments not exceed $2.000 billion in the aggregate. As of March 31, 2016, we had $1.680 billion of the combined legal and debt exclusion remaining.
As of and through March 31, 2016, we were in compliance with the required covenants.
As of March 31, 2016, we had an aggregate of $1.000 billion outstanding under our unsecured term loan facilities and $1.000 billion outstanding as of December 31, 2015. These facilities include an unsecured term loan facility entered into in August 2013 (2013 Term Loan) which had $250 million outstanding as of March 31, 2016 and December 31, 2015, along with an unsecured term loan credit facility entered into in April 2015 (2015 Term Loan) which had $750 million outstanding as of March 31, 2016 and December 31, 2015.
Borrowings under the 2013 Term Loan bear interest at LIBOR plus an interest margin between 1.00 percent and 1.75 percent (currently 1.50 percent) based on our corporate credit ratings and consolidated leverage ratio. We repaid $150 million of our 2013 Term Loan facility in 2015. As a result and in accordance with the credit agreement, the remaining outstanding balance is payable with $10 million due in the fourth quarter of 2017, $20 million due in each of the first and second quarters of 2018 and the remaining principal amount due at the final maturity date in August 2018. The 2013 Term Loan borrowings are repayable at any time without premium or penalty. Our term loan facility requires that we comply with certain covenants, including financial covenants with respect to maximum leverage and minimum interest coverage, consistent with the 2015 Term Loan facility. The maximum leverage ratio requirement is 4.5 times, and our actual leverage ratio as of March 31, 2016 is 2.9 times. The minimum interest coverage ratio requirement is 3.0 times, and our actual interest coverage ratio as of March 31, 2016 is 7.0 times.
On April 10, 2015, we entered into a new $750 million unsecured term loan credit facility (2015 Term Loan) which matures on August 3, 2020. The 2015 Term Loan was funded on August 3, 2015 and was used to partially fund the AMS Portfolio Acquisition, including the payment of fees and expenses. Term loan borrowings under this facility bear interest at LIBOR plus an interest margin of between 1.00 percent and 1.75 percent (currently 1.50 percent), based on our corporate credit ratings and consolidated leverage ratio. The 2015 Term Loan requires quarterly principal payments of $38 million commencing in the third quarter of 2017,
and the remaining principal amount is due at the final maturity date of August 3, 2020. The 2015 Term Loan agreement requires that we comply with certain covenants, including financial covenants with respect to maximum leverage and minimum interest coverage, consistent with our revolving credit facility. The maximum leverage ratio requirement is 4.5 times, and our actual leverage ratio as of March 31, 2016 is 2.9 times. The minimum interest coverage ratio requirement is 3.0 times, and our actual interest coverage ratio as of March 31, 2016 is 7.0 times.
We had senior notes outstanding of $4.650 billion as of March 31, 2016 and December 31, 2015. In May 2015, we completed the offering of $1.850 billion in aggregate principal amount of senior notes consisting of $600 million in aggregate principal amount of 2.850% notes due 2020, $500 million in aggregate principal amount of 3.375% notes due 2022 and $750 million in aggregate principal amount of 3.850% notes due 2025. The net proceeds from the offering of the notes, after deducting underwriting discounts and estimated offering expenses, were approximately $1.831 billion. We used a portion of the net proceeds from the senior notes offering to redeem $400 million aggregate principal amount of our 5.500% notes due November 2015 and $600 million aggregate principal amount of our 6.400% notes due June 2016. The remaining senior notes offering proceeds, together with the 2015 Term Loan, were used to fund the AMS Portfolio Acquisition. We recorded a charge of $45 million in interest expense, during the second quarter of 2015, for premiums, accelerated amortization of debt issuance costs, and investor discount costs net of interest rate hedge gains related to the early debt extinguishment.
Our senior notes were issued in public offerings, are redeemable prior to maturity and are not subject to any sinking fund requirements. Our senior notes are unsecured, unsubordinated obligations and rank on parity with each other. These notes are effectively junior to borrowings under our credit and security facility, to the extent if borrowed by our subsidiaries and to liabilities of our subsidiaries (see Other Arrangements below).
We maintain a $300 million credit and security facility secured by our U.S. trade receivables maturing on June 9, 2017. The credit and security facility requires that we maintain a maximum leverage covenant consistent with our revolving credit facility. The maximum leverage ratio requirement is 4.5 times, and our actual leverage ratio as of March 31, 2016 is 2.9 times. We had no borrowings outstanding under this facility as of March 31, 2016 and December 31, 2015.
We have accounts receivable factoring programs in certain European countries that we account for as sales under FASB ASC Topic 860, Transfers and Servicing. These agreements provide for the sale of accounts receivable to third parties, without recourse, of up to approximately $411 million as of March 31, 2016. We have no retained interests in the transferred receivables, other than collection and administrative responsibilities and, once sold, the accounts receivable are no longer available to satisfy creditors in the event of bankruptcy. We de-recognized $178 million of receivables as of March 31, 2016 at an average interest rate of 1.7 percent, and $151 million as of December 31, 2015 at an average interest rate of 2.4 percent.
In addition, we have uncommitted credit facilities with a commercial Japanese bank that provide for borrowings, promissory notes discounting and receivables factoring of up to 21.000 billion Japanese yen (approximately $187 million as of March 31, 2016). We de-recognized $146 million of notes receivable and factored receivables as of March 31, 2016 at an average interest rate of 1.6 percent and $132 million of notes receivable as of December 31, 2015 at an average interest rate of 1.6 percent. De-recognized accounts and notes receivable are excluded from trade accounts receivable, net in the accompanying unaudited condensed consolidated balance sheets.
As of March 31, 2016 we had outstanding letters of credit of $43 million, as compared to $44 million as of December 31, 2015, which consisted primarily of bank guarantees and collateral for workers' compensation insurance arrangements. As of March 31, 2016 and December 31, 2015, none of the beneficiaries had drawn upon the letters of credit or guarantees; accordingly, we did not recognize a related liability for our outstanding letters of credit in our consolidated balance sheets as of March 31, 2016 or December 31, 2015. We believe we will generate sufficient cash from operations to fund these arrangements and intend to fund these arrangements without drawing on the letters of credit.
NOTE F – RESTRUCTURING-RELATED ACTIVITIES
On an ongoing basis, we monitor the dynamics of the economy, the healthcare industry, and the markets in which we compete. We continue to assess opportunities for improved operational effectiveness and efficiency, and better alignment of expenses with revenues, while preserving our ability to make the investments in research and development projects, capital and our people that we believe are essential to our long-term success. As a result of these assessments, we have undertaken various restructuring initiatives in order to enhance our growth potential and position us for long-term success. These initiatives are described below.
2014 Restructuring Plan
On October 22, 2013, our Board of Directors approved, and we committed to, a restructuring initiative (the 2014 Restructuring Plan). The 2014 Restructuring Plan is intended to build on the progress we have made to address financial pressures in a changing global marketplace, further strengthen our operational effectiveness and efficiency and support new growth investments. Key activities under the plan include continued implementation of our ongoing Plant Network Optimization (PNO) strategy, continued focus on driving operational efficiencies and ongoing business and commercial model changes. The PNO strategy is intended to simplify our manufacturing plant structure by transferring certain production lines among facilities. Other activities involve rationalizing organizational reporting structures to streamline various functions, eliminate bureaucracy, increase productivity and better align resources to business strategies and marketplace dynamics. These activities were initiated in the fourth quarter of 2013 and were substantially completed by the end of 2015, except for certain ongoing actions associated with our PNO strategy, which we expect to be substantially completed by the end of 2016.
The implementation of the 2014 Restructuring Plan will result in total pre-tax charges of approximately $255 million to $270 million, and approximately $240 million to $255 million of these charges are estimated to result in cash outlays, of which we have made payments of $212 million through March 31, 2016. We have recorded related costs of $242 million since the inception of the plan, and recorded a portion of these expenses as restructuring charges and the remaining portion through other lines within our consolidated statements of operations.
The following table provides a summary of our estimates of costs associated with the 2014 Restructuring Plan by major type of cost:
(1) Consists primarily of consulting fees and costs associated with contract cancellations.
(2) Comprised of other costs directly related to the 2014 Restructuring Plan, including program management, accelerated depreciation, and costs to transfer product lines among facilities.
We recorded net restructuring charges pursuant to our restructuring plans of $3 million in the first quarter of 2016 and $6 million in the first quarter of 2015. In addition, we recorded expenses within other lines of our accompanying unaudited condensed consolidated statements of operations related to our restructuring initiatives of $10 million in the first quarter of 2016 and $16 million in the first quarter of 2015.
The following presents these costs (credits) by major type and line item within our accompanying unaudited condensed consolidated statements of operations, as well as by program:
All charges incurred in the first quarter of 2016 are related to the 2014 Restructuring Plan.
Termination benefits represent amounts incurred pursuant to our ongoing benefit arrangements and amounts for “one-time” involuntary termination benefits, and have been recorded in accordance with FASB ASC Topic 712, Compensation – Non-retirement Postemployment Benefits and FASB ASC Topic 420, Exit or Disposal Cost Obligations (Topic 420). We expect to record additional termination benefits related to our restructuring initiatives throughout 2016 as we complete our 2014 Restructuring Plan. Other restructuring costs, which represent primarily consulting fees and costs related to contract cancellations, are being recorded as incurred in accordance with Topic 420. Accelerated depreciation is being recorded over the adjusted remaining useful life of the related assets, and production line transfer costs are being recorded as incurred.
As of March 31, 2016, we incurred cumulative restructuring charges related to our 2014 Restructuring Plan of $128 million and restructuring-related costs of $114 million since we committed to the plan. The following presents these costs by major type (in millions):
We made cash payments of $23 million in the first quarter of 2016 associated with our restructuring initiatives and as of March 31, 2016, we had made total cash payments of $212 million related to our 2014 Restructuring Plan since committing to the plan. These payments were made using cash generated from operations, and are comprised of the following:
Our restructuring liability is primarily comprised of accruals for termination benefits. The following is a rollforward of the termination benefit liability associated with our 2014 Restructuring Plan, which is reported as a component of accrued expenses included in our accompanying unaudited condensed balance sheets (in millions):
In addition to our accrual for termination benefits, we had a $4 million liability as of March 31, 2016 and a $3 million liability as of December 31, 2015 for other restructuring-related items.
