Results of operations and the estimated fair value of acquired assets and assumed liabilities are recorded in the consolidated financial statements from the date of acquisition.
Pro forma results of operations for the business combinations completed during fiscal 2016 have not been presented because the effects of these acquisitions, individually and in the aggregate, would not have been material to Cadence’s financial results.
The fair values of acquired intangible assets and assumed liabilities were determined using significant inputs that are not observable in the market.
For an additional description of these fair value calculations, see Note 16 in the notes to the consolidated financial statements.
A trust for the benefit of the children of Lip-Bu Tan, Cadence’s President, Chief Executive Officer, or CEO, and director, owned less than 2% of Rocketick Technologies Ltd. , one of the acquired companies, and Mr.  Tan and his wife serve as co-trustees of the trust and disclaim pecuniary and economic interest in the trust.
The Board of Directors of Cadence reviewed the transaction and concluded that it was in the best interests of Cadence to proceed with the transaction.
Mr.  Tan recused himself from the Board of Directors’ discussion of the valuation of Rocketick Technologies Ltd.  and on whether to proceed with the transaction.
A financial advisor provided a fairness opinion to Cadence in connection with the transaction.2014 Acquisitions During fiscal 2014, Cadence acquired Jasper Design Automation, Inc. , or Jasper, a privately held provider of formal analysis solutions based in Mountain View, California.
The acquired technology complements Cadence’s existing system design and verification platforms.
Total cash consideration for Jasper, after taking into account adjustments for certain costs, and cash held by Jasper at closing of $28.7 million, was $139.4 million.
Cadence will also make payments to certain employees through the third quarter of fiscal 2017 subject to continued employment and other conditions.
Cadence also completed two other business combinations during fiscal 2014 for total cash consideration of $27.5 million, after taking into account cash acquired of $2.1 million.
Acquisition-related Transaction Costs Transaction costs associated with acquisitions were $1.1 million, $0.7 million and $3.7 million during fiscal 2016, 2015 and 2014, respectively.
These costs consist of professional fees and administrative costs and were expensed as incurred in Cadence’s consolidated income statements.
NOTE 8.
GOODWILL AND ACQUIRED INTANGIBLES Goodwill The changes in the carrying amount of goodwill during fiscal 2016 and 2015 were as follows:
## Table 0 ##
Cadence completed its annual goodwill impairment test during the third quarter of fiscal 2016 and determined that the fair value of Cadence’s single reporting unit substantially exceeded the carrying amount of its net assets and that no impairment existed.
We assess fair value based on estimated cash flow projections that utilize appropriate discount and/or capitalization rates, third party appraisals, and available market information.
Estimates of future cash flows are based on a number of factors including historical operating results, known and anticipated trends, and market and economic conditions.
The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant.
We record acquired “above and below” market leases at their fair value, using a discount rate which reflects the risks associated with the leases acquired, equal to the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed-rate renewal options for below-market leases.
Other intangible assets acquired include amounts for in-place lease values that are based on our evaluation of the specific characteristics of each tenant’s lease.
Factors to be considered include estimates of carrying costs during hypothetical expected lease-up periods, market conditions, and costs to execute similar leases.
In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions.
In estimating costs to execute similar leases, we consider leasing commissions, legal and other related costs.
Real estate assets are periodically reviewed for potential impairment by comparing the carrying amount to the expected undiscounted future cash flows to be generated from the assets.
If the sum of the expected future net undiscounted cash flows is less than the carrying amount of the property, we will recognize an impairment loss by adjusting the asset’s carrying amount to its estimated fair value.
Fair value for properties to be held and used is based on the present value of the future cash flows expected to be generated from the asset.
Properties held for sale are recorded at the lower of carrying amount or fair value less costs to dispose.
Our ability to accurately predict future cash flows impacts the determination of fair value, which may significantly impact our reported results of operations.
Results of Operations Comparison of the year ended December 31, 2005 to the year ended December 31, 2004 Rental and other revenue.
MOB rental revenue increased 35% to $126.9 million for the year ended December 31, 2005.
The increase in MOB rental revenue of $33.2 million primarily relates to the additive effect of our acquisitions in 2005 and 2004, which contributed $26.7 million to rental revenues year over year.
Triple-net lease rental revenues increased 13% to $325.3 million for the year ended December 31, 2005.
The increase in triple-net lease rental revenue of $37.7 million primarily relates to the additive effect of our acquisitions in 2005 and 2004, as detailed below:

Tenant Lease Expirations The following table shows tenant lease expirations, including those related to DFLs, for the next 10 years and thereafter at our consolidated properties, assuming that none of the tenants exercise any of their renewal or purchase options, unless otherwise noted below, and excludes properties in our SHOP segment and assets held for sale as of and for the year ended December 31, 2018 (dollars and square feet in thousands):
## Table 2 ##
(1) Includes month-to-month leases.
(2) The most recent month’s (or subsequent month’s, if acquired in the most recent month) base rent, including additional rent floors and cash income from DFLs, annualized for 12 months.
Base rent does not include tenant recoveries, additional rents in excess of floors and non-cash revenue adjustments (i. e. , straight-line rents, amortization of market lease intangibles, DFL non-cash interest and deferred revenues).
See the “Tenant Purchase Options” section of Note 6 to the Consolidated Financial Statements for additional information on leases subject to purchase options.

LEGAL PROCEEDINGS Except as described below, we are not aware of any legal proceedings or claims that we believe could have, individually or taken together, a material adverse effect on our financial condition, results of operations or cash flows.
See “Legal Proceedings” section of Note 11 to the Consolidated Financial Statements for information regarding legal proceedings, which information is incorporated by reference in this Item 3.
ITEM 4.
MINE SAFETY DISCLOSURES None.
In November 2016, we issued $45 million of fixed rate term notes in two tranches to two insurance companies.
Principal payments commence in 2023 and 2028 and the notes mature in 2029 and 2034, respectively.
The notes carry interest rates of 2.87 and 3.10, respectively.
We used proceeds of the notes to pay down borrowings under our revolving credit facility.
In January 2015, we issued $75 million of fixed rate term notes to an insurance company.
Principal payments commence in 2020 and the notes mature in 2030.
The notes carry an interest rate of 3.52 percent.
We used proceeds of the notes to pay down borrowings under our revolving credit facility.
At December 31, 2016, we had available borrowing capacity of $310.8 million under this facility.
We believe that the combination of cash, available borrowing capacity and operating cash flow will provide sufficient funds to finance our existing operations for the foreseeable future.
Our total debt increased to $323.6 million at December 31, 2016 compared with $249.0 million at December 31, 2015, as our cash flows generated in the U.
S were more than offset by our share repurchase activity and our purchase of Aquasana.
As a result, our leverage, as measured by the ratio of total debt to total capitalization, was 17.6 percent at the end of 2016 compared with 14.7 percent at the end of 2015.
Our U. S.  pension plan continues to meet all funding requirements under ERISA regulations.
We were not required to make a contribution to our pension plan in 2016 but made a voluntary $30 million contribution due to escalating Pension Benefit Guaranty Corporation insurance premiums.
We forecast that we will not be required to make a contribution to the plan in 2017 and we do not plan to make any voluntary contributions in 2017.
For further information on our pension plans, see Note 10 of the Notes to Consolidated Financial Statements.
During 2016, our Board of Directors authorized the purchase of an additional 3,000,000 shares of our Common Stock.
In 2016, we repurchased 3,273,109 shares at an average price of $41.30 per share and a total cost of $135.2 million.
A total of 4,906,403 shares remained on the existing repurchase authorization at December 31, 2016.
Depending on factors such as stock price, working capital requirements and alternative investment opportunities, such as acquisitions, we expect to spend approximately $135 million on share repurchase activity in 2017 using a 10b5-1 repurchase plan.
In addition, we may opportunistically repurchase an additional $65 million of our shares in 2017.
We have paid dividends for 77 consecutive years with payments increasing each of the last 25 years.
We paid dividends of $0.48 per share in 2016 compared with $0.38 per share in 2015.
In January 2017, we increased our dividend by 17 percent and anticipate paying dividends of $0.56 per share in 2017.
Aggregate Contractual Obligations A summary of our contractual obligations as of December 31, 2016, is as follows:
## Table 3 ##
As of December 31, 2016, our liability for uncertain income tax positions was $4.2 million.
Due to the high degree of uncertainty regarding timing of potential future cash flows associated with these liabilities, we are unable to make a reasonably reliable estimate of the amount and period in which these liabilities might be paid.
We utilize blanket purchase orders to communicate expected annual requirements to many of our suppliers.
Requirements under blanket purchase orders generally do not become committed until several weeks prior to our scheduled unit production.
The purchase obligation amount presented above represents the value of commitments that we consider firm.

Pension Benefits Xcel Energy has several noncontributory, defined benefit pension plans that cover almost all employees.
Generally, benefits are based on a combination of years of service, the employee’s average pay and, in some cases, social security benefits.
Xcel Energy’s policy is to fully fund into an external trust the actuarially determined pension costs recognized for ratemaking and financial reporting purposes, subject to the limitations of applicable employee benefit and tax laws.
In addition to the qualified pension plans, Xcel Energy maintains a supplemental executive retirement plan (SERP) and a nonqualified pension plan.
The SERP is maintained for certain executives that were participants in the plan in 2008, when the SERP was closed to new participants.
The nonqualified pension plan provides unfunded, nonqualified benefits for compensation that is in excess of the limits applicable to the qualified pension plans.
The total obligations of the SERP and nonqualified plan as of Dec.  31, 2015 and 2014 were $41.8 million and $46.5 million, respectively.
In 2015 and 2014, Xcel Energy recognized net benefit cost for financial reporting for the SERP and nonqualified plans of $9.5 million and $4.7 million, respectively.
Benefits for these unfunded plans are paid out of Xcel Energy’s consolidated operating cash flows.
Xcel Energy bases the investment-return assumption on expected long-term performance for each of the investment types included in its pension asset portfolio.
Xcel Energy considers the historical returns achieved by its asset portfolio over the past 20-year or longer period, as well as the long-term return levels projected and recommended by investment experts.
Xcel Energy continually reviews its pension assumptions.
The pension cost determination assumes a forecasted mix of investment types over the long-term.  ?
Investment returns in 2015 were below the assumed level of 7.09 percent; ?
Investment returns in 2014 were above the assumed level of 7.05 percent; ?
Investment returns in 2013 were below the assumed level of 6.88 percent; and ?
In 2016, Xcel Energy’s expected investment return assumption is 6.87 percent.
The assets are invested in a portfolio according to Xcel Energy’s return, liquidity and diversification objectives to provide a source of funding for plan obligations and minimize the necessity of contributions to the plan, within appropriate levels of risk.
The principal mechanism for achieving these objectives is the projected allocation of assets to selected asset classes, given the long-term risk, return, and liquidity characteristics of each particular asset class.
There were no significant concentrations of risk in any particular industry, index, or entity.
Market volatility can impact even well-diversified portfolios and significantly affect the return levels achieved by pension assets in any year.
The following table presents the target pension asset allocations for Xcel Energy at Dec.  31 for the upcoming year:
## Table 4 ##
Xcel Energy’s ongoing investment strategy is based on plan-specific investment recommendations that seek to minimize potential investment and interest rate risk as a plan’s funded status increases over time.
The investment recommendations result in a greater percentage of long-duration fixed income securities being allocated to specific plans having relatively higher funded status ratios and a greater percentage of growth assets being allocated to plans having relatively lower funded status ratios.
The aggregate projected asset allocation presented in the table above for the master pension trust results from the plan-specific strategies.
SPP and MISO Complaints Regarding RTO Joint Operating Agreement (JOA) — SPP and MISO have been engaged in a longstanding dispute regarding the interpretation of their JOA, which is intended to coordinate RTO operations along the MISO/SPP system boundary.
SPP and MISO disagree over MISO’s authority to transmit power between the traditional MISO region in the Midwest and the Entergy system.
Several cases were filed with the FERC by MISO and SPP between 2011 and 2014.
In June 2014, the FERC set the issues for settlement judge and hearing procedures.
In January 2016, FERC approved a settlement between SPP, MISO and other parties that resolves various disputed matters and provide a defined settlement compensation plan by MISO to SPP.
MISO will pay SPP $16 million for the two-year retroactive period and $16 million annually prospectively, subject to a true-up.
Separate settlement discussions regarding the MISO tariff change to recover SPP charges are ongoing.
NSP-Minnesota and NSP-Wisconsin expect to be able to recover any resulting MISO charges in retail rates.
In January 2016, SPP filed a proposal regarding distribution of the revenues to SPP members, including SPS.
FERC approval is pending.
The revenue allocated to SPS is not expected to be material.

The only equity securities that are publicly traded are common shares of Xcel Energy Inc.
The diluted earnings and EPS of each subsidiary as well as the ROE of each subsidiary discussed below do not represent a direct legal interest in the assets and liabilities allocated to such subsidiary but rather represent a direct interest in our assets and liabilities as a whole.
Ongoing diluted EPS and ongoing ROE for Xcel Energy and by subsidiary are financial measures not recognized under GAAP.
Ongoing diluted EPS is calculated by dividing the net income or loss attributable to the controlling interest of each subsidiary, adjusted for certain nonrecurring items, by the weighted average fully diluted Xcel Energy Inc.  common shares outstanding for the period.
Ongoing ROE is calculated by dividing the net income or loss attributable to the controlling interest of Xcel Energy or each subsidiary, adjusted for certain nonrecurring items, by each entity’s average common stockholders’ or stockholder’s equity.
We use these non-GAAP financial measures to evaluate and provide details of earnings results.
We believe these measurements are useful to investors to evaluate the actual and projected financial performance and contribution of our subsidiaries.
These non-GAAP financial measures should not be considered as alternatives to measures calculated and reported in accordance with GAAP.
