free cash flow .
our non-gaap financial measures also include free cash flow which we define as cash provided by -used in operating activities less the amount of property and equipment purchased .
management believes that information regarding free cash flow provides investors with an important perspective on the cash available to invest in our business and fund ongoing operations .
however our calculation of free cash flow may not be comparable to similar measures used by other companies .
we believe these non-gaap financial measures are helpful in understanding our past financial performance and our future results .
our non-gaap financial measures are not meant to be considered in isolation or as a substitute for comparable gaap measures and should be read only in conjunction with our consolidated financial statements prepared in accordance with gaap .
our management regularly uses our supplemental non-gaap financial measures internally to understand manage and evaluate our business and make operating decisions .
these non-gaap measures are among the primary factors management uses in planning for and forecasting future periods .
compensation of our executives is based in part on the performance of our business based on certain of these non-gaap measures .
we monitor the following non-gaap financial measures : .

liquidity and capital resources .
our primary sources of liquidity are cash flows from operations available cash reserves and debt capacity available under various credit facilities .
we could raise additional funds through other public or private debt or equity financings .
we may use our available or additional funds to among other things .
facilitate purchases redemptions and exchanges of shares and pay dividends ; .
acquire complementary businesses or technologies ; .
take advantage of opportunities including more rapid expansion ; or .
develop new services and solutions .
as of august 31 2019 cash and cash equivalents were $ 6 .
1 billion compared with $ 5 .
1 billion as of august 31 2018 .
cash flows from operating investing and financing activities as reflected in our consolidated cash flows statements are summarized in the following table : .
operating activities : the $ 600 million year-over-year increase in operating cash flow was due to higher net income as well as changes in operating assets and liabilities including an increase in accounts payable partially offset by higher tax disbursements .
investing activities : the $ 506 million increase in cash used was primarily due to higher spending on business acquisitions and investments .
for additional information see note 6 -business combinations to our consolidated financial statements under item 8 “ financial statements and supplementary data .
” .
financing activities : the $ 58 million increase in cash used was primarily due to an increase in cash dividends paid as well as an increase in purchases of shares partially offset by an increase in proceeds from share issuances and a decrease in the purchase of additional interests in consolidated subsidiaries .
for additional information see note 14 -material transactions affecting shareholders ’ equity to our consolidated financial statements under item 8 “ financial statements and supplementary data .
” .
we believe that our current and longer-term working capital investments and other general corporate funding requirements will be satisfied for the next twelve months and thereafter through cash flows from operations and to the extent necessary from our borrowing facilities and future financial market activities .
substantially all of our cash is held in jurisdictions where there are no regulatory restrictions or material tax effects on the free flow of funds .
in addition domestic cash inflows for our irish parent principally dividend distributions from lower-tier subsidiaries have been sufficient to meet our historic cash requirements and we expect this to continue into the future .

we do not consider these items to be indicative of our core operating performance .
the items that are non-cash include depreciation and amortization expense and stock-based compensation expense .
adjusted ebitda is a measure used by management to understand and evaluate our core operating performance and trends and to generate future operating plans make strategic decisions regarding the allocation of capital and invest in initiatives that are focused on cultivating new markets for our solutions .
in particular the exclusion of certain expenses in calculating adjusted ebitda facilitates comparisons of our operating performance on a period-to-period basis .
adjusted ebitda is not a measure calculated in accordance with gaap .
we believe that adjusted ebitda provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors .
nevertheless use of adjusted ebitda has limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under gaap .
some of these limitations are : -1 although depreciation and amortization are non-cash charges the capitalized software that is amortized will need to be replaced in the future and adjusted ebitda does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements ; -2 adjusted ebitda does not reflect changes in or cash requirements for our working capital needs ; .
-3 adjusted ebitda does not reflect the potentially dilutive impact of equity-based compensation ; -4 adjusted ebitda does not reflect tax payments or receipts that may represent a reduction or increase in cash available to us ; and -5 other companies including companies in our industry may calculate adjusted ebitda or similarly titled measures differently which reduces the usefulness of the metric as a comparative measure .
because of these and other limitations you should consider adjusted ebitda alongside our other gaap-based financial performance measures net loss and our other gaap financial results .
