	Organization and Basis of Presentation
	Organization
	Interface Security Systems Holdings, Inc. (“Holdings”) is a Delaware corporation. Holdings is a technology company engaged in the sale, provisioning, installation, monitoring and maintenance of physical security, secure managed broadband, digital voice and Internet Protocol ("IP") based applications to commercial and residential customers throughout the United States. Holdings is primarily owned by SunTx Capital Partners, L.P. and its affiliates (“SunTx Capital Partners”), which owns approximately 88% of the voting power of Holdings' parent company, Interface Master Holdings, Inc. ("Master Holdings") on a fully diluted basis. Holdings owns 100% of the outstanding membership interests of its principal operating subsidiary, Interface Security Systems, L.L.C. (“Interface Systems”). Collectively, Holdings and Interface Systems are referred to herein as the "Company" or "Interface".  In the third quarter of 2013, Holdings acquired all of the remaining noncontrolling interest in The Greater Alarm Company, Inc. (“GAC”) and merged Westec Acquisition Corp. (“Westec”) and GAC into Interface Systems.
	Basis of Presentation
	The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All significant transactions and account balances between entities included in the consolidated financial statements have been eliminated in consolidation. The consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the Company’s financial position as of September 30, 2014, and the results of operations for the three and nine months ended September 30, 2014 and 2013. The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information; accordingly, certain information and footnote disclosures typically included in the Company’s annual financial statements have been condensed or omitted from this report. In management’s opinion, all adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the periods disclosed have been made. These unaudited condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company's registration statement on Form S-4 which was declared effective by the SEC on July 30, 2014 (the "Registration Statement"). Information presented as of December 31, 2013 is derived from audited financial statements. The results of operations for the interim periods are not necessarily indicative of the results expected for the full year.
	Operating Model and Liquidity
	The Company conducts business in one operating segment, which is identified by the Company based on how resources are allocated and operating decisions are made. A majority of the Company’s revenues are generated within the Unites States and a majority of the Company’s long-lived assets are located within the United States. Management evaluates performance and allocates resources based on the Company as a whole. The Company’s business model is based on generating long-term contracts with customers to provide on-going monitoring, maintenance and related services that generate profitable recurring monthly revenue ("RMR"). For transactions in which we retain ownership of the systems, any amounts collectible upfront are deferred and amortized over the longer of the average customer life or the initial term of the contract. The Company makes a one-time investment in sales and installation cost to create new customers internally and this investment is not capitalized. Certain other industry participants purchase customers through customer contract purchases, and as a result, may capitalize the full cost to purchase these customer contracts, as compared to our organic generation of new customers, where the majority of customer creation costs is expensed. The Company generates substantial operating losses as a result of having to expense the majority of its investment in subscriber RMR growth.
	The Company invested direct costs of $12.9 million and $10.9 million to create new RMR of $0.6 million and $0.3 million for the three months ended September 30, 2014 and 2013, respectively, and $28.0 million and $32.2 million to create new RMR of $0.9 million and $1.1 million for the nine months ended September 30, 2014 and 2013, respectively. The Company's cash use for operations for the three and nine months ended September 30, 2014 is primarily due to these investments.
	Security technology monitoring companies are generally valued based on a multiple of the RMR associated with the customer contracts and these purchase multiples do vary based on performance metrics, scale and market conditions. Management believes that there is significant value created for the Company’s stockholders resulting from the steady growth in the Company’s RMR at historical investment levels. The Company has demonstrated year-on-year increases in monitoring and managed service revenues from adding new RMR that generates high cash flow margins. As of September 30, 2014, the Company is actively billing approximately $7.8 million of RMR and has a Contracted Backlog of RMR contracts totaling $2.5 million of which one-third is expected to be installed in the fourth quarter of 2014.
	Throughout the course of the Company’s history, it has been able to adjust the level of RMR growth and related investment based on the capital available. If the Company were to cease its internal growth strategy and no longer invest in creating new RMR, it would generate future positive cash flows that could be used to pay down its outstanding debt.
	In January 2013, the Company closed an offering of 9 1/4% Senior Secured Notes due 2018 (the "Senior Secured Notes") in an aggregate principal amount of $230.0 million, the proceeds of which were used to repay its then existing revolver balance, senior subordinated note, subordinated notes payable and the fees and expenses associated with the offering. In addition, the Company had $32.0 million drawn and $6.1 million available for borrowing under its revolving credit facility at September 30, 2014. See Note 7.
	The Company used $39.7 million and $19.4 million of cash for operations for the nine months ended September 30, 2014 and 2013, respectively, and had positive working capital of $46.9 million as of September 30, 2014 and negative working capital of $13.2 million (excluding assets and liabilities held for sale) as of December 31, 2013. In addition, as of September 30, 2014, the Company had $262.0 million of total indebtedness.
	Other Comprehensive Income
	The Company did not recognize any other comprehensive income during the three and nine months ended September 30, 2014 and 2013.

Sale of Transferred Assets	'
	Sale of Transferred Assets
	Pursuant to an Asset Purchase Agreement (the “Asset Purchase Agreement”), dated as of January 9, 2014 (the “Closing Date”), by and among My Alarm Center, LLC, d/b/a Alarm Capital Alliance (“Buyer”), and Interface Systems, the Company sold certain residential customer contracts and related assets and liabilities used exclusively in, or necessary to conduct, the alarm system sales, installation, repair, maintenance and monitoring services of the Company’s Hawk Security Services brand (“Hawk”) in the State of Texas (the “Transferred Assets”) to the Buyer. The total purchase price for the Transferred Assets was approximately $42.8 million of which approximately $40.7 million was paid in cash to the Company and $2.1 million was deposited in an escrow account on the Closing Date. Approximately $2.0 million was recorded as restricted cash on the balance sheet as of December 31, 2013. The funds remained in escrow for six months following the Closing Date with a 30 day settlement period and served as the exclusive source of recovery for customary indemnification obligations with respect to the Company’s representations, warranties and covenants under the Asset Purchase Agreement and certain adjustments to the purchase price in the event the customer attrition rate applicable to the Transferred Assets differed from specified targets. The Company agreed to provide Buyer with certain specified transition services to allow for the efficient transition of the Transferred Assets to Buyer for six months following the Closing Date with a 30 day settlement period, unless extended by mutual agreement. This escrow balance was released and received by the Company in August 2014. The Company continues to operate in the residential alarm monitoring business under the Interface brand and the Hawk branded services were not clearly distinguishable operationally or for financial reporting purposes. The Company used a portion of the net proceeds to redeem all of the issued and outstanding shares of its Class G Preferred Stock and Class F Preferred Stock and part of its Class E Preferred Stock and to pay a cash dividend in an aggregate amount of approximately $27.3 million to the stockholders as permitted under the indenture governing the Senior Secured Notes.
	As of December 31, 2013, the Transferred Assets met the criteria for assets held for sale under Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 360, Property, Plant and Equipment. As such, the assets and liabilities to be sold were reclassified as held for sale. Assets held for sale on the Company's balance sheet as of December 31, 2013 included accounts receivable of approximately $0.3 million, inventory of $0.3 million and property, plant and equipment of $3.6 million. Liabilities held for sale on the Company's balance sheet as of December 31, 2013 included accrued expenses of $0.1 million, customer deposits of $0.5 million, and deferred revenue of $0.8 million.

		$	262,000		$	256,500
	In January 2013, the Company closed an offering of Senior Secured Notes for $230.0 million, the proceeds of which were used to repay the existing revolver balance, senior subordinated promissory note, subordinated notes payable and the fees and expenses associated with the offering. The Senior Secured Notes have a maturity date of January 15, 2018 and have an interest rate of 9.25% with semi-annual interest payments due on January 15th and July 15th. The Senior Secured Notes are jointly and severally guaranteed by each of the Company's future domestic restricted subsidiaries and are secured by substantially all of the Company’s and the guarantors’ existing and future tangible and intangible assets.
	In connection with the issuance of the Senior Secured Notes, the Company entered into a registration rights agreement with the initial purchasers of the Senior Secured Notes. The Registration Statement was filed pursuant to the Company's obligations under this registration rights agreement on July 9, 2014. The Registration Statement was declared effective on July 30, 2014. The exchange offer expired on August 27, 2014 and all of the Senior Secured Notes were tendered by the holders and exchanged.
	The Company also closed a $45.0 million revolving credit facility in January 2013, senior to the Senior Secured Notes, which allows the Company to borrow the lesser of $45.0 million or up to 5 times RMR. The revolving credit facility matures on January 15, 2018 and had $32.0 million drawn and availability of $6.1 million at September 30, 2014. The revolving credit facility includes a $1.0 million sub-limit for the issuance of letters of credit, and the amount outstanding reduces the available borrowing capacity. As of September 30, 2014 and December 31, 2013, the Company had $0.1 million in letters of credit outstanding.
	Borrowings under the revolving line of credit bear interest at a floating rate per year equal to the higher of (A) the rate (adjusted for statutory reserve requirements for Eurocurrency liabilities) at which Eurodollar deposits are offered for a period equal to one, two, three, or six months, as quoted on Reuters Screen LIBOR01 Page (or any successor / similar page or service) as of 11:00 a.m., London time, on the day that is two London banking days preceding the applicable interest determination date and (B) 0.50%, plus 3.25% (3.75% as of September 30, 2014). The revolving credit facility includes financial covenants, including: (i) a covenant not to exceed a revolving facility usage to eligible RMR ratio of 5.0 to 1.0, (ii) a covenant to maintain a minimum fixed charge coverage of 1.25 to 1.0, and (iii) a covenant not to exceed a maximum gross attrition rate of 13.0% at any time. The revolving credit facility is secured by a first priority perfected lien on all of the same assets that secure the Senior Secured Notes. The revolving credit facility also provides that, upon the occurrence of certain events of default, the Company’s obligations thereunder may be accelerated and any lending commitments terminated. Such events of default include payment defaults to the lenders, material inaccuracies of representations and warranties, covenant defaults, cross‑defaults to other material indebtedness, voluntary and involuntary bankruptcy proceedings, material money judgments, certain change of control events and other customary events of default. As of September 30, 2014, the Company was in compliance with all of the restrictive and financial covenants.
	On May 16, 2014, the Company entered into a waiver, consent and second amendment to its revolving credit facility with the lender, which (i) amended the revolving credit facility to permit, and in which the lender consented to, certain events in connection with certain reorganization transactions; (ii) amended the revolving credit facility to provide that a ‘‘change of control’’ in the indenture governing the 12.50% / 14.50% Senior Contingent Cash Pay Notes of Master Holdings (the "Master Holding Notes") will constitute a ‘‘change in control’’ under the revolving credit facility; and (iii) waived any defaults in connection with the Company’s prior substantial doubt about its ability to continue as a going concern. On August 15, 2014, the Company entered into a third amendment to its Revolving Credit Facility with the lender, which increased the amount of capital leases, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business, in an aggregate principal amount, including all new indebtedness incurred to renew, refund, refinance, replace, defease or discharge any existing indebtedness incurred not to exceed $5,000,000 at any time outstanding, less the outstanding amount of any capital leases disclosed.
	On May 30, 2014, the Company completed a corporate reorganization with Master Holdings in connection with the closing of a $115.0 million offering of the Master Holdings Notes. The Master Holding Notes are not guaranteed by any of Master Holdings subsidiaries, including Holdings and Interface Systems. Pursuant to the reorganization, each of SunTx Capital Partners and certain of its affiliates, Michael T. Shaw, Michael J. McLeod, Kenneth Obermeyer and certain other stockholders of Holdings exchanged all of their shares of each class of common stock of Holdings and each class of preferred stock of Holdings for an equal number of shares of common stock and preferred stock of Master Holdings with substantially similar terms as the shares of Holdings. In addition, Master Holdings used $71.6 million of the proceeds of the offering to purchase shares of Class A common stock and Class B common stock of Holdings. Holdings and Interface Systems intend to use the consideration from the sale of shares of Holdings common stock to Master Holdings to make cash interest payments on the Senior Secured Notes and for general corporate purposes, including to fund growth initiatives. Immediately following the consummation of these transactions, Master Holdings owned approximately 99% of each class of common stock of Holdings and at least 99% of each class of Holdings’ preferred stock. Subsequent to these transactions, the remaining stockholders of Holdings exchanged all of their shares of each class of common stock and preferred stock of Holdings for an equal number of shares of common stock and preferred stock of Master Holdings. As a result, Master Holdings now owns 100% of the common stock and preferred stock of Holdings.
	Based upon outstanding indebtedness as of September 30, 2014, aggregate annual maturities on the total borrowings under all debt agreements as of September 30, 2014 are as follows (in thousands):

	At September 30, 2014, the Senior Secured Notes traded at a range of 102.25 to 103.25 based upon available market information. The range of the estimated fair value of the Company's Senior Secured Notes was $235.2 million to $237.5 million as of September 30, 2014 and is classified with Level 2 (see Note 8) of the valuation hierarchy. The remaining portion of the Company’s debt is considered a Level 3 input supported by little or no market activity.

Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company has established a process for determining fair value of its financial assets and liabilities using available market information or other appropriate valuation methodologies. Fair value is based upon quoted market prices, where available. If such valuation methods are not available, fair value is based on internally or externally developed models using market-based or independently-sourced market parameters, where available. Fair value may be subsequently adjusted to ensure that those assets and liabilities are recorded at fair value. The use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value estimate as of the Company’s reporting date.
	Fair value guidance establishes a three-level hierarchy for disclosure of fair value measurements, based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date, as follows:
	•	Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
	•	Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset and liability, either directly or indirectly, for substantially the full term of the financial instrument.
	•	Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement.
	The carrying amounts of cash, receivables and payables approximate fair value because of the short maturity of those instruments.

Mezzanine Equity	'
	Mezzanine Equity
	Mezzanine equity in the consolidated balance sheets as of September 30, 2014 and December 31, 2013 is comprised of the Company’s Class A, Class C, Class E, Class F and Class G preferred stock, including accrued dividends. Holdings’ adopted an amended and restated certificate of incorporation on May 29, 2014 authorizing 70,000 shares of Class A preferred stock with a par value of $1.00 per share, 60,000 shares of Class C preferred stock with a par value of $1.00 per share, and 50,000 shares of Class E preferred stock with a par value of $1.00 per share. Pursuant to the Company’s amended and restated certificate of incorporation, none of the classes of preferred stock are entitled to receive any dividends.
	Prior to adopting the amended and restated certificate of incorporation, the Company’s certificate of incorporation, as amended (the “prior charter”), also authorized 50,000 shares of Class F preferred stock with a par value of $1.00 per share and 5,000 shares of Class G preferred stock with a par value of $1.00 per share. In addition, each share of Class E preferred stock was convertible into one share of Class A common stock and one share of Class C preferred stock at any time at the option of the stockholder. Pursuant to the prior charter, each series of the preferred stock accrued dividends cumulatively on a daily basis at the rate of 10% per annum (12.9% for the Class F preferred stock), due and payable upon a liquidation event (as defined in the prior charter). Dividends ceased to accrue upon adoption of the Company’s amended and restated certificate of incorporation.
	The Company’s preferred stock each contain an optional redemption that allows the Company to redeem the preferred shares at its option, and a mandatory redemption upon a Disposition Event (as defined in Holdings’ amended and restated certificate of incorporation), in each case, at their stated redemption value plus all accrued and unpaid dividends. Since SunTx and its affiliates control the appointment of the directors of Holdings through its ownership of the substantial majority of the voting power of Master Holdings, SunTx Capital Partners could require the Company to redeem the preferred shares or otherwise force a Disposition Event. As such, the Company considers the preferred stock and associated dividends to be payable at the option of the holder and not solely within the Company’s control. Accordingly, the Company’s preferred stock is recorded as redeemable and / or convertible securities (outside of permanent equity) in the accompanying consolidated balance sheets.
	Class C and Class E have liquidation preference rights over Class A preferred stock. The distribution of any liquidation is set forth in Holdings’ amended and restated certificate of incorporation.
	In January 2014, the Company used a portion of the net proceeds from the sale of the Transferred Assets to redeem all of the issued and outstanding shares of the Company’s Class G preferred stock and Class F preferred stock and part of the Company’s Class E preferred stock and to pay a cash dividend in an aggregate amount of approximately $27.3 million to the stockholders as permitted under the indenture governing the Senior Secured Notes.

See consolidated statement of changes in stockholder’s equity (deficit) for details of shares issued and outstanding. In addition, each share of Class A common stock is convertible into one share of Class B common stock at any time at the option of the stockholder.
	On December 13, 2001 (date of inception), members of Company management purchased shares of Holdings’ stock at prices determined by the Board of Directors of the Company. The purchase price for such shares was paid to Holdings with an aggregate of $250,000 in recourse promissory notes payable to the Company, with the shares pledged as collateral. The outstanding balance of the promissory notes of $0.1 million December 31, 2013 is reflected as a reduction in stockholders’ equity (deficit) in the accompanying consolidated balance sheet. Subsequent to the date of inception, additional shares of Holdings’ stock were purchased with cash or issuance of additional promissory notes by certain members of management. In April 2014, all of the promissory notes issued by management were paid in full and terminated.

	In April 2010, the Company entered into a Management Services Agreement (the "Management Agreement") with SunTx Capital Management Corp. (“SunTx Management”), the general partner of SunTx Capital Partners. Pursuant to the Management Agreement, SunTx Management provides certain management services to the Company. The term of the Management Agreement is ten years, which may be terminated by SunTx Management upon 90 days written notice to the Company. The Company pays SunTx Management, on a monthly basis, SunTx Management’s customary fees for rendering the management services, as set forth in a statement delivered to the Company from time to time. These fees are anticipated under the Management Agreement not to exceed $500,000 on an annual basis. The Company also reimburses SunTx Management for all out-of-pocket expenses and payroll costs of in-house legal counsel incurred by SunTx Management in connection with the management services and pays all taxes resulting from its purchase or use of the management services. In addition to the management services fee, in connection with any acquisitions, dispositions or debt or equity financings by Interface Systems or any of its affiliates, Interface Systems will pay SunTx Management a fee which shall not exceed an amount equal to 2% of the total enterprise value involved in the transaction (the "Equity Fee"). The total enterprise value is determined by the board of directors of Interface Systems.  Under the indenture for the Master Holdings Notes, the Company is not permitted to pay the fees to SunTx Management under the Management Agreement unless, among other requirements, the Company is permitted to incur at least $1.00 of additional indebtedness pursuant to the fixed charge coverage ratio test set forth in the indenture for the Senior Secured Notes.  The Company was not permitted to incur such $1.00 of additional indebtedness for the trailing four quarters ended September 30, 2014 and therefore, no fees were paid to SunTx Management during the period from June 2014 to September 2014. Fees paid to SunTx Management were $0.1 million for the three months ended September 30, 2013 and $0.2 million and $0.4 million for the nine months ended September 30, 2014 and 2013, respectively.
	In March 2014, the Company entered into a Settlement and Advance agreement with a former employee of the Company and shareholder of Master Holdings.  The agreement releases all current and future claims against the Company in return for a non-interest bearing loan of $500,000 to the former employee and shareholder.  The loan is secured by a promissory note and a pledge agreement securing 50% of the 2,074.02 shares of Master Holdings' common stock (representing 7.0% of the total outstanding common stock) owned by the former employee and shareholder.

	Recently Issued Accounting Standards
	In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), ("ASU 2014-09"). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is not permitted. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and footnote disclosures.
	In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, ("ASU 2014-15"). ASU 2014-15 is intended to provide guidance about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period. If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-15 to have a material impact on its consolidated financial statements and footnote disclosures.

	Condensed Consolidating Financial Information
	In January 2013, Holdings and Interface Systems, as co-issuers, issued $230.0 million aggregate principal amount of Senior Secured Notes (see Note 7). Pursuant to the indenture governing the Senior Secured Notes, such notes are fully and unconditionally and jointly and severally guaranteed by each of the Company's future domestic restricted subsidiaries and are secured by substantially all of the Company's and the guarantors' existing and future tangible and intangible assets. Separate condensed consolidating information is not included because Interface Systems is a wholly-owned subsidiary and co-issuer of the Senior Secured Notes and Holdings has insignificant independent assets or operations. There are no significant restrictions on the ability of Holdings to obtain funds from its subsidiary. Based on these facts, and in accordance with Securities and Exchange Commission Regulation S-X Rule 3-10, "Financial statements of guarantors and issuers of guaranteed securities registered or being registered," the Company is not required to provide condensed consolidating financial information for its subsidiary. All consolidated amounts in the Company's financial statements are representative of its subsidiary.

	Basis of Presentation
	The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All significant transactions and account balances between entities included in the consolidated financial statements have been eliminated in consolidation. The consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the Company’s financial position as of September 30, 2014, and the results of operations for the three and nine months ended September 30, 2014 and 2013. The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information; accordingly, certain information and footnote disclosures typically included in the Company’s annual financial statements have been condensed or omitted from this report. In management’s opinion, all adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the periods disclosed have been made. These unaudited condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company's registration statement on Form S-4 which was declared effective by the SEC on July 30, 2014 (the "Registration Statement"). Information presented as of December 31, 2013 is derived from audited financial statements. The results of operations for the interim periods are not necessarily indicative of the results expected for the full year.
Operating Model and Liquidity	'
	Operating Model and Liquidity
	The Company conducts business in one operating segment, which is identified by the Company based on how resources are allocated and operating decisions are made. A majority of the Company’s revenues are generated within the Unites States and a majority of the Company’s long-lived assets are located within the United States. Management evaluates performance and allocates resources based on the Company as a whole. The Company’s business model is based on generating long-term contracts with customers to provide on-going monitoring, maintenance and related services that generate profitable recurring monthly revenue ("RMR"). For transactions in which we retain ownership of the systems, any amounts collectible upfront are deferred and amortized over the longer of the average customer life or the initial term of the contract. The Company makes a one-time investment in sales and installation cost to create new customers internally and this investment is not capitalized. Certain other industry participants purchase customers through customer contract purchases, and as a result, may capitalize the full cost to purchase these customer contracts, as compared to our organic generation of new customers, where the majority of customer creation costs is expensed. The Company generates substantial operating losses as a result of having to expense the majority of its investment in subscriber RMR growth.
	The Company invested direct costs of $12.9 million and $10.9 million to create new RMR of $0.6 million and $0.3 million for the three months ended September 30, 2014 and 2013, respectively, and $28.0 million and $32.2 million to create new RMR of $0.9 million and $1.1 million for the nine months ended September 30, 2014 and 2013, respectively. The Company's cash use for operations for the three and nine months ended September 30, 2014 is primarily due to these investments.
	Security technology monitoring companies are generally valued based on a multiple of the RMR associated with the customer contracts and these purchase multiples do vary based on performance metrics, scale and market conditions. Management believes that there is significant value created for the Company’s stockholders resulting from the steady growth in the Company’s RMR at historical investment levels. The Company has demonstrated year-on-year increases in monitoring and managed service revenues from adding new RMR that generates high cash flow margins. As of September 30, 2014, the Company is actively billing approximately $7.8 million of RMR and has a Contracted Backlog of RMR contracts totaling $2.5 million of which one-third is expected to be installed in the fourth quarter of 2014.
	Throughout the course of the Company’s history, it has been able to adjust the level of RMR growth and related investment based on the capital available. If the Company were to cease its internal growth strategy and no longer invest in creating new RMR, it would generate future positive cash flows that could be used to pay down its outstanding debt.
	In January 2013, the Company closed an offering of 9 1/4% Senior Secured Notes due 2018 (the "Senior Secured Notes") in an aggregate principal amount of $230.0 million, the proceeds of which were used to repay its then existing revolver balance, senior subordinated note, subordinated notes payable and the fees and expenses associated with the offering. In addition, the Company had $32.0 million drawn and $6.1 million available for borrowing under its revolving credit facility at September 30, 2014. See Note 7.
	The Company used $39.7 million and $19.4 million of cash for operations for the nine months ended September 30, 2014 and 2013, respectively, and had positive working capital of $46.9 million as of September 30, 2014 and negative working capital of $13.2 million (excluding assets and liabilities held for sale) as of December 31, 2013. In addition, as of September 30, 2014, the Company had $262.0 million of total indebtedness.
