Costs and Expenses Cost of Product Revenue Cost of product revenue for fiscal 2015 increased by $2.6 million, or 7%, to $39.9 million from $37.3 million for fiscal 2014.
Gross margin was 83% for fiscal 2015 and 80% for fiscal 2014.
The increase in cost of product revenues was related to increased Impella demand and higher production volume and costs to support growing demand for our Impella products.
Gross margin was impacted favorably by higher manufacturing production volume, fewer shipments of AIC consoles, improved efficiencies in manufacturing production and a favorable Euro in the second half of fiscal 2015 Research and Development Expenses Research and development expenses for fiscal 2015 increased by $5.3 million, or 17%, to $36.0 million from $30.7 million in fiscal 2014.
The increase in research and development expenses was primarily due to operating expenses associated with the ECP business in Berlin that we acquired in July 2014 and a $1.5 million up-front license payment made in April 2014 for optical sensor technology.
Selling, General and Administrative Expenses Selling, general and administrative expenses for fiscal 2015 increased by $18.4 million, or 17%, to $125.7 million from $107.3 million in fiscal 2014.
The increase in selling, general and administrative expenses was primarily due to the hiring of additional U. S.  field sales and clinical personnel, increased spending on marketing initiatives as we continue to educate physicians on the benefits of hemodynamic support, higher stock-based compensation expense, higher excise taxes associated with the medical device tax in the U. S.  and legal and professional expenses related to the ECP acquisition.
These amounts were partially offset by lower legal expenses during fiscal 2015.
Income Tax Provision We recorded an income tax benefit of $84.9 million in fiscal 2015 compared to an income tax expense of $1.2 million in fiscal 2014.
The income tax benefit in fiscal 2015 was comprised of an $87.1 million deferred tax benefit primarily due to the release of our valuation allowance on certain of our deferred tax assets in the quarter ended March 31, 2015, partially offset by a current income tax provision of $2.2 million in U.
S and Germany.
The income tax provision for fiscal 2014 was comprised of income taxes in Germany and income taxes related to the deferred tax liability associated with tax deductible goodwill.
Net Income During fiscal 2015, we recognized net income of $113.7 million, or $2.80 per basic share and $2.65 per diluted share, compared to $7.4 million, or $0.19 per basic share and $0.18 per diluted share for fiscal 2014.
Our net income for fiscal 2015 included an income tax benefit of $84.9 million, primarily due to the release of our valuation allowance on certain of our deferred tax assets.
The increase in net income in fiscal 2015 was also due to higher Impella product revenue in the U. S.  and Europe.
Liquidity and Capital Resources At March 31, 2016, our total cash, cash equivalents, and short and long-term marketable securities totaled $213.1 million, an increase of $67.1 million compared to $146.0 million at March 31, 2015.
The increase in our cash, cash equivalents, and short and long-term marketable securities was due primarily to positive cash flows from operations in fiscal 2016.
Following is a summary of our cash flow activities:
## Table 0 ##
We assess the impact of interest rate movements on the value of our financial assets, financial liabilities and derivatives using hypothetical test scenarios that assume either upward or downward 100 basis point parallel shifts in the yield curve from prevailing interest rates, reflecting changes in either credit spreads or the risk-free rate.
The following table sets forth the net estimated potential loss in fair value on these financial instruments from a hypothetical 100 basis point upward shift as of December 31, 2018 and 2017.
This table is presented on a gross basis and excludes offsetting impacts to insurance liabilities that are not considered financial liabilities under U.
S GAAP.
This scenario results in the greatest net exposure to interest rate risk of the hypothetical scenarios tested at those dates.
While the test scenario is for illustrative purposes only and does not reflect our expectations regarding future interest rates or the performance of fixed income markets, it is a near-term, reasonably possible hypothetical change that illustrates the potential impact of such events.
These test scenarios do not measure the changes in value that could result from non-parallel shifts in the yield curve which we would expect to produce different changes in discount rates for different maturities.
As a result, the actual loss in fair value from a 100 basis point change in interest rates could be different from that indicated by these calculations.
The estimated changes in fair values do not include separate account assets.
## Table 1 ##
(1) Includes assets classified as “Fixed maturities, available-for-sale, at fair value,” “Assets supporting experience-rated contractholder liabilities, at fair value” and “Fixed maturities, trading, at fair value.
” Approximately $354 billion and $370 billion as of December 31, 2018 and 2017, respectively, of fixed maturities are classified as available-for-sale.
(2) Excludes any offsetting impact of derivative instruments purchased to hedge changes in the embedded derivatives.
Amounts reported net of third-party reinsurance.
(3) Excludes approximately $324 billion and $306 billion as of December 31, 2018 and 2017, respectively, of insurance reserve and deposit liabilities which are not considered financial liabilities.
We believe that the interest rate sensitivities of these insurance liabilities would serve as an offset to the net interest rate risk of the financial assets and liabilities, including investment contracts.
Under U. S.  GAAP, the fair value of the embedded derivatives for certain variable annuity and other living benefit features, reflected in the table above, includes the impact of the market’s perception of our NPR.
For more information on NPR related to the sensitivity of the embedded derivatives to our NPR credit spread, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Accounting Policies & Pronouncements—Application of Critical Accounting Estimates—Sensitivities for Insurance Assets and Liabilities” above.
For an additional discussion of our variable annuity optional living benefit guarantees accounted for as embedded derivatives and related derivatives used to hedge the changes in fair value of these embedded derivatives, see “Market Risk Related to Certain Variable Annuity Products” below.
For additional information about the key estimates and assumptions used in our determination of fair value, see Note 6 to the Consolidated Financial Statements.
For information on the impacts of a sustained low interest rate environment, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Summary—Impact of a Low Interest Rate Environment” above.
Market Risk Related to Equity Prices We have exposure to equity risk through asset/liability mismatches, including our investments in equity securities held in our general account investment portfolio and unhedged exposure in our insurance liabilities, principally related to certain variable annuity living benefit feature embedded derivatives.
Our equity-based derivatives primarily hedge the equity risk embedded in these living benefit feature embedded derivatives, and are also part of our capital hedging program.
Changes in equity prices create risk that the resulting changes in asset values will differ from the changes in the value of the liabilities relating to the underlying or hedged products.
Additionally, changes in equity prices may impact other items including, but not limited to, the following: ?
Asset-based fees earned on assets under management or contractholder account value; ?
Estimated total gross profits and the amortization of deferred policy acquisition and other costs; and ?
Net exposure to the guarantees provided under certain products.
