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, 2015 , and the results of operations for the three and nine months ended September 30, 2015 and 2014 . 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. These unaudited condensed financial statements should be read in conjunction with the financial statements and the notes thereto filed with the Company's Annual Report on Form 10-K for the year ended December 31, 2014 (the “Form 10-K”), which was filed with the SEC on March 31, 2015. Information presented as of December 31, 2014 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. Revision During the third quarter of 2015 , the Company identified that immaterial amounts of certain sales incentives and discounts provided to its customers were improperly recorded as cost of services instead of being recorded as a direct offset to services revenue. In accordance with Accounting Standards Codification (“ASC”) 605-50, Revenue Recognition, these sales incentives and discounts should be recorded as an offset to revenues instead of being reported as a cost of services. Pursuant to the guidance of Staff Accounting Bulletin (“SAB”) No. 99, Materiality, the Company concluded that the errors were not material to any of its prior year consolidated financial statements. The accompanying consolidated statement of operations for the nine months ended September 30, 2015 includes a cumulative revision relating to these errors for the six months ended June 30, 2015 and were immaterial to the years previously reported. These revisions did not have any effect on income (loss) from operations, net income (loss), cash flows, or non-GAAP reporting metrics nor did they affect the Company’s past compliance with debt covenants. The following table compares previously reported service revenues, total revenues, cost of services, total costs and expenses to as adjusted amounts for the each of the three month periods ended March 31 and June 30, 2015 and the six months ended June 30, 2015 : Three Months Ended March 31, 2015 As Reported Correction As Adjusted Services revenue $ 32,869 $ (4,340 ) $ 28,529 Total revenue 38,302 (4,340 ) 33,962 Cost of services 32,915 (4,340 ) 28,575 Total costs and expenses 48,712 (4,340 ) 44,372 Three Months Ended June 30, 2015 As Reported Correction As Adjusted Services revenue $ 34,235 $ (1,792 ) $ 32,443 Total revenue 38,511 (1,792 ) 36,719 Cost of services 29,421 (1,792 ) 27,629 Total costs and expenses 45,070 (1,792 ) 43,278 Six Months Ended June 30, 2015 As Reported Correction As Adjusted Services revenue $ 67,104 $ (6,132 ) $ 60,972 Total revenue 76,813 (6,132 ) 70,681 Cost of services 62,336 (6,132 ) 56,204 Total costs and expenses 93,782 (6,132 ) 87,650 Going Concern As of March 31, 2015, the Company could not provide assurance that it would achieve positive cash flow during high volume net new recurring monthly revenue (“RMR”) growth periods, produce sufficient cash flow to meet all of its obligations if it were to cease investing in creating new RMR and replacing attrition (“Steady State”) or that it could raise additional debt and/or equity capital. These factors raised substantial doubt about the Company’s ability to continue as a going concern. On June 30, 2015 , the Company entered into a consent and fifth amendment to the Revolving Credit Facility (defined in Note 7) with Capital One, N.A. (“Capital One”) to permit, and in which Capital One consented to, certain events in connection with the establishment of Grand Master, as the owner of 100 % of the capital stock of Master Holdings (“Grand Master Restructuring”). In connection with the restructuring, Grand Master closed a private placement of $ 67.0 million aggregate principal amount of unsecured notes on July 7, 2015. Also on July 7, 2015, Grand Master made a capital contribution through its subsidiaries of $ 49.8 million of the net proceeds from the offering to fund the Company's growth initiatives. On June 30, 2015 , the Company entered into a Master Services Agreement with a specialty retailer and distributor of professional beauty supplies, pursuant to which the Company will provide a fully-managed bundled services solution to approximately 4,200 locations. A portion of the net proceeds from the notes offering is expected to be used to fund the deployment of this contract, which is expected to be completed in February 2016 . As a result of the capital contribution from Grand Master, management believes its near-term financial position has improved significantly since March 31, 2015 and sufficient liquidity exists to fund the deployment of the Master Services Agreement and pay the interest payments of $ 10.6 million due under the 9 1/4% Senior Secured Notes due 2018 (the “Notes”) in January 2016 and July 2016. 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. Management evaluates performance and allocates resources based on the Company as a whole. A majority of the Company’s revenues are generated within the United States and a majority of the Company’s long-lived assets are located primarily 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, management, maintenance and related services that generate profitable RMR. The Company makes a one-time investment in sales and installation cost to create new customers internally and this investment is generally not capitalized. The Company generates substantial operating losses as a result of expensing the majority of its investment in subscriber RMR growth. The Company incurred net direct costs of $ 11.7 million and $ 12.9 million to create new RMR of $ 0.5 million and $ 0.6 million for the three months ended September 30, 2015 and 2014 , respectively, and incurred net direct costs of $ 53.8 million and $ 28.0 million to create new RMR of $ 2.2 million and $ 0.9 million for the nine months ended September 30, 2015 and 2014 , respectively. The Company's cash used for operations for the three and nine months ended September 30, 2015 is primarily due to installation costs to create new RMR. Security, technology and monitoring companies are generally valued based on a multiple of the RMR associated with the customer contracts and these multiples vary based on performance metrics, scale and market conditions. Management believes there is significant value created for the Company’s investors resulting from the steady growth in the Company’s RMR at historical investment levels. The Company has demonstrated historical increases in monitoring and managed service revenues from adding new RMR that generates high cash flow margins. As of September 30, 2015 , the Company is actively billing approximately $ 10.1 million of RMR and has a backlog of new RMR associated with fully executed customer contracts for services that are pending installation (“Contracted Backlog”) totaling $ 1.7 million of which approximately $ 1.0 million is expected to be completed by the end of 2015 . 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 enter Steady State, it would likely generate future positive cash flows that could be used to pay down its outstanding debt. Steady State is a non-GAAP financial metric often used by industry lenders, investment bankers, credit rating agencies and physical security companies to assess ongoing cash flow generating capabilities of a security company assuming the company invests only in acquiring new customers to offset attrition and maintain a steady base of RMR. During high volume net new RMR growth periods, management cannot provide assurance that the Company will achieve positive cash flow or have the ability to raise additional debt and/or equity capital. In the event that sufficient funds cannot be obtained to grow RMR and pay interest payments, management could elect to operate in Steady State and scale back the RMR growth to a level that would significantly reduce its investment costs. A majority of the expenses related to the sales and marketing activity for new RMR opportunities spent in 2015 would be eliminated as well as other fixed overhead and operating costs associated with installing new RMR and Contracted Backlog. In March 2015, the Company received a waiver from Capital One for any default under its Revolving Credit Facility (defined in Note 7) resulting from the going concern emphasis in the audit report for the year ended December 31, 2014. The Company also entered into a fourth amendment to the Revolving Credit Facility increasing the facility from $ 45.0 million to $ 50.0 million. The Company had $ 36.0 million drawn and $ 13.8 million available for borrowing under its Revolving Credit Facility at September 30, 2015 . See Note 7. The Company used $ 25.0 million and $ 39.7 million of cash for operations for the nine months ended September 30, 2015 and 2014 , respectively, and had positive working capital of $ 26.2 million as of September 30, 2015 and $ 20.0 million as of December 31, 2014 . In addition, as of September 30, 2015 , the Company had $ 266.0 million of total indebtedness. The Company expects to use its cash on hand for operations during the remainder of 2015. |
