were previously deemed to be indefinitely reinvested outside the  U.S., under current tax laws we would incur additional tax expense  upon such repatriation. We believe that cash available and borrowing capacity under our  existing credit facilities should be sufficient to finance anticipated  operating activities, capital improvements and expansions, as well  as debt repayments, for the foreseeable future. We continue to  monitor the factors that drive our markets and strive to maintain our  leadership and competitive advantage in the markets we serve while  aligning our cost structures with market conditions. $6.8 million in contract settlements related to Fiscal 2012 matters.  During Fiscal 2012, the cash used in operations of $6.0 million was  primarily the result of increased unbilled contract receivables based  on progress billing milestones. Cash flow provided by operations of  $15.5 million in Fiscal 2011 resulted primarily from the increase in  accounts payable. Purchases of property, plant and equipment during Fiscal 2013  totaled $74.4 million compared to $29.1 million and $7.3 million  in Fiscal 2012 and 2011, respectively. A significant portion of the  investments in the last two fiscal years was to acquire land and build  facilities in the United States and Canada to support our continued  expansion in our key markets, including the oil and gas markets  and Canadian oil sands region. Costs related to upgrades and  enhancements to our Business Systems were also incurred during  Fiscal 2013; which are expected to be placed into service in the  second quarter of our fiscal year ending September 30, 2014. Net cash used in financing activities was $0.5 million in Fiscal  2013. Net cash provided by financing activities was $1.3 million  during Fiscal 2012 due to cash being received from the exercise of  stock options. Net cash used in financing activities was $0.8 million  during Fiscal 2011. During Fiscal 2013, net cash provided by operating activities was  $91.8 million. During Fiscal 2012, net cash used in operating  activities was $6.0 million and in Fiscal 2011, net cash provided by  operating activities was $15.5 million. Cash flow from operations is  primarily influenced by demand for our products and services and  is impacted as our progress payment terms with our customers  are matched with the payment terms with our suppliers. During  Fiscal 2013, our cash from operations increased over Fiscal 2012,  primarily due to increased net income, as well as the increase in  billing in excess of costs and estimated earnings on uncompleted  contracts and the collection of contracts receivable based on the  progress billing milestones. Additionally in Fiscal 2013, we received  At September 30, 2013, our long-term contractual obligations were limited to debt and leases. The table below details our commitments by  type of obligation, including interest if applicable, and the period that the payment will become due (in thousands). The lease on our previously occupied Canadian facility does not expire until July 2023; however, we have sublet that facility through July 2019.  As of September 30, 2013, the total unrecognized tax benefit related to uncertain tax positions was $3.8 million. We estimate that none  of this will be paid within the next 12 months. However, we believe that it is reasonably possible that within the next 12 months, the total  unrecognized tax benefits will decrease by approximately 1% due to the expiration of certain statutes of limitations in various state and local  jurisdictions. We are unable to make reasonably reliable estimates regarding the timing of future cash outflows, if any, associated with the  remaining unrecognized tax benefits.  21 As of September 30, 2013, Payments Due by Period: Long-Term Debt Obligations Capital Lease Obligations Operating Lease Obligations Total Less than 1 year  $ 408  $ 16  $ 4,741  $ 5,165 1 to 3 years 813  —  6,462  7,275 3 to 5 years 809 —  4,099  4,908 More than 5 years 1,606 — 6,405  8,011 Total long-term contractual obligations $ 3,636 $ 16 $ 21,707  $ 25,359 Investing Activities Financing Activities Operating Activities Contractual and Other Obligations
