(1) The working capital amounts exclude restricted cash and cash equivalents amounts of $191.8 million in 2017, $126.5 million in 2016, $180.9 million in 2015, $121.0 million in 2014 and $125.5 million in 2013.
(2) Same store sales growth is calculated including only sales from stores that also had sales in the comparable period of the prior year.
International same store sales growth is calculated similarly to domestic same store sales growth.
Changes in international same store sales are reported on a constant dollar basis which reflects changes in international local currency sales.
The 53rd week in fiscal 2015 had no impact on reported same store sales growth amounts.
(3) In connection with our 2017 Recapitalization, the Company issued $1.9 billion of fixed and floating rate notes.
A portion of the proceeds from the 2017 Recapitalization was used to repay the remaining $910.2 million in outstanding principal under the 2012 fixed rate notes, pre-fund a portion of the principal and interest payable on the 2017 fixed and floating rate notes and pay transaction fees and expenses.
The Company also used a portion of the proceeds from the 2017 Recapitalization to enter into a $1.0 billion accelerated share repurchase agreement to repurchase the Company’s common stock.
Refer to Note 4 of the consolidated financial statements for additional detail related to the 2017 Recapitalization.
(4) In connection with our 2015 Recapitalization, the Company issued $1.3 billion of fixed rate notes.
A portion of the proceeds from the 2015 Recapitalization was used to make an optional prepayment of approximately $551.3 million in aggregate principal amount of its 2012 fixed rate notes, at par, pay scheduled principal catch-up amounts on its 2012 fixed rate notes, make an interest reserve deposit, pre-fund a portion of the principal and interest payable on the 2015 fixed rate notes and pay transaction fees and expenses.

(5) The 2015 fiscal year includes 53 weeks and the 2017, 2016, 2014 and 2013 fiscal years each include 52 weeks.
The following table illustrates the main components of our cash flows:
## Table 1 ##
Operating Activities Cash provided by operating activities increased $51.7 million in 2017 from 2016, primarily due to an increase in net income of $63.2 million.
Net income in 2017 included a $27.2 million benefit from the adoption of ASU 2016-09, which requires tax benefits on equity-based compensation to be recorded as a reduction to the provision from income taxes in net income and as a component of cash provided by operating activities.
In 2016, these tax benefits were recorded directly to stockholders’ deficit and as a financing activity in the statement of cash flows.
Cash provided by operating activities was also positively impacted by an increase in non-cash amounts of $18.1 million.
These increases were offset in part by the negative impact of changes in operating assets and liabilities of $29.6 million, primarily related to the timing of payments on accounts payable and accrued liabilities during 2017 as compared to 2016.
Cash provided by operating activities decreased $4.5 million in 2016 from 2015, primarily due to the negative impact of changes in operating assets and liabilities of $23.7 million resulting from the timing of payments for accounts payable and accrued liabilities in 2016 as compared to 2015.
This decrease was offset in part by an increase in net income of $21.9 million.
We are focused on continually improving our net income and cash flow from operations and management expects to continue to generate positive cash flows from operating activities for the foreseeable future.
Investing Activities During fiscal 2017, cash used in investing activities was $149.0 million, which consisted primarily of $90.0 million of capital expenditures (driven by investments in our technological initiatives, supply chain centers and Companyowned stores) and the increase in restricted cash and cash equivalents of $65.3 million.
These uses of cash were offset in part by the proceeds from the sale of assets of $6.8 million.
During fiscal 2016, cash used in investing activities was $0.8 million, which consisted primarily of $58.6 million of capital expenditures (driven by investments related to the reimaging of our existing Company-owned stores and investments in our supply chain centers and training facilities, our proprietary internally developed point-of-sale system, our digital ordering platform, our internal enterprise systems and other technology initiatives), offset in part by the decrease in restricted cash and cash equivalents of $54.4 million and by proceeds from the sale of assets of $4.9 million.
During fiscal 2015, cash used in investing activities was $109.3 million, which consisted primarily of $63.3 million of capital expenditures (driven by investments related to the reimaging of our existing Company-owned stores and investments in our supply chain centers and training facilities, our proprietary internally developed point-of-sale system, our digital ordering platform, our internal enterprise systems and other technology initiatives), increases in restricted cash and cash equivalents of $60.0 million, and offset by proceeds from the sale of assets of $12.7 million.
Financing Activities During fiscal 2017, cash used in financing activities was $197.1 million.
We issued $1.9 billion of debt in connection with our 2017 Recapitalization, which was offset by purchases of common stock of $1.06 billion, repayments of long-term debt of $928.2 million (of which, $910.2 million was repayment of the remaining 2012 Fixed Rate Notes using a portion of the proceeds received from the 2017 Recapitalization), funding dividend payments to our shareholders of $84.3 million, and cash paid for financing costs related to our 2017 Recapitalization of $16.8 million.
We also made $9.4 million in tax payments for restricted stock upon vesting and received proceeds of $6.1 million from the exercise of stock options.
During fiscal 2016, cash used in financing activities was $375.8 million.
Purchases of common stock totaled $300.3 million, repayments of long-term debt and capital lease obligations totaled $122.3 million, and funding dividend payments to our shareholders totaled $73.9 million.
The net tax impact of equity-based compensation was $42.5 million, proceeds from issuance of debt (from our draws on our variable funding note facility) totaled $63.0 million, and proceeds from the exercise of stock options totaled $15.2 million.
In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments.
ASU 2016- 13 requires companies to measure credit losses utilizing a methodology that reflects expected credit losses and requires a consideration of a broader range of reasonable and supportable information to inform credit loss estimates.
ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including those interim periods within those fiscal years.
The Company is currently assessing the impact of adopting this standard, but based on a preliminary assessment, does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.
In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18), which requires that restricted cash and cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows.
ASU 2016-18 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and a retrospective transition method is required.
The Company currently presents changes in restricted cash and cash equivalents in the investing section of its consolidated statement of cash flows.
The new guidance will not impact financial results, but will result in a change in the presentation of restricted cash and restricted cash equivalents within the statement of cash flows.
The Company currently plans to adopt this guidance in the first quarter of 2018 using the retrospective approach.
In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 35): Simplifying the Test for Goodwill Impairment, or ASU 2017-04.
ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating “Step 2” from the goodwill impairment test.
ASU 2017-04 is effective for public companies’ annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019.
Early adoption is permitted for annual goodwill impairment tests performed on testing dates after January 1, 2017.
The Company is currently assessing the impact of adopting this standard, but based on a preliminary assessment, does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.
Contractual obligations The following is a summary of our significant contractual obligations at December 31, 2017.
## Table 2 ##
(1) We have outstanding long-term secured notes with varying maturities.
For additional information, see Note 4 of the Notes to Consolidated Financial Statements under “Part II – Item 8 – Financial Statements and Supplementary Data.
” (2) Represents interest payments on our 2015 and 2017 Notes and 2017 Variable Funding Notes.
The interest rate on the 2017 Variable Funding Notes will be payable at a per year rate equal to LIBOR plus 150 basis points.
(3) The principal portion of the capital lease obligation amounts above, which totaled $5.4 million at December 31, 2017, are classified as debt in our consolidated financial statements.
(4) We lease certain retail store and supply chain center locations, supply chain vehicles, various equipment and our World Resource Center under leases with expiration dates through 2033.
Liabilities for unrecognized tax benefits of $1.8 million are excluded from the above table, as we are unable to make a reasonably reliable estimate of the amount and period of payment.
For additional information on unrecognized tax benefits see Note 6 to the consolidated financial statements included in this Form 10-K.  Off-balance sheet arrangements We are party to letters of credit and, to a lesser extent, financial guarantees with off-balance sheet risk.
Our exposure to credit loss for letters of credit and financial guarantees is represented by the contractual amounts of these instruments.
Total conditional commitments under letters of credit as of December 31, 2017 were approximately $46.7 million and relate to our insurance programs and supply chain center leases.
The Company has guaranteed lease payments related to certain franchisees’ lease arrangements.
The maximum amount of potential future payments under these guarantees is $1.5 million as of December 31, 2017.
We believe that none of these arrangements has or is likely to have a material effect on our results of operations, financial condition, revenues or expenses, capital expenditures or liquidity.
the analysis of our depreciation studies.
Changes in the estimated service lives of our assets and their related depreciation rates are implemented prospectively.
Under group depreciation, the historical cost (net of salvage) of depreciable property that is retired or replaced in the ordinary course of business is charged to accumulated depreciation and no gain or loss is recognized.
The historical cost of certain track assets is estimated using (i) inflation indices published by the Bureau of Labor Statistics and (ii) the estimated useful lives of the assets as determined by our depreciation studies.
The indices were selected because they closely correlate with the major costs of the properties comprising the applicable track asset classes.
Because of the number of estimates inherent in the depreciation and retirement processes and because it is impossible to precisely estimate each of these variables until a group of property is completely retired, we continually monitor the estimated service lives of our assets and the accumulated depreciation associated with each asset class to ensure our depreciation rates are appropriate.
In addition, we determine if the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by our depreciation studies.
Any deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the applicable classes of assets.
For retirements of depreciable railroad properties that do not occur in the normal course of business, a gain or loss may be recognized if the retirement meets each of the following three conditions: (i) is unusual, (ii) is material in amount, and (iii) varies significantly from the retirement profile identified through our depreciation studies.
A gain or loss is recognized in other income when we sell land or dispose of assets that are not part of our railroad operations.
When we purchase an asset, we capitalize all costs necessary to make the asset ready for its intended use.
However, many of our assets are self-constructed.
A large portion of our capital expenditures is for replacement of existing track assets and other road properties, which is typically performed by our employees, and for track line expansion and other capacity projects.
Costs that are directly attributable to capital projects (including overhead costs) are capitalized.
Direct costs that are capitalized as part of selfconstructed assets include material, labor, and work equipment.
Indirect costs are capitalized if they clearly relate to the construction of the asset.
General and administrative expenditures are expensed as incurred.
Normal repairs and maintenance are also expensed as incurred, while costs incurred that extend the useful life of an asset, improve the safety of our operations or improve operating efficiency are capitalized.
These costs are allocated using appropriate statistical bases.
Total expense for repairs and maintenance incurred was $2.3 billion for 2013, $2.1 billion for 2012, and $2.2 billion for 2011.
Assets held under capital leases are recorded at the lower of the net present value of the minimum lease payments or the fair value of the leased asset at the inception of the lease.
Amortization expense is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease.12.
