A second critical accounting policy and estimate which requires judgment of management is the estimated allowance for doubtful accounts and contractual adjustments. We have based our estimates on historical collection amounts, current contracts with payors, current changes of the facts and circumstances relating to these matters and certain negotiations with related payors.
A third critical accounting policy is consolidation of our investment in partnerships or limited liability companies (LLCs) where we, as the general partner or managing member, exercise effective control, even though our ownership is less than 50%. The consolidated financial statements include our accounts, our wholly-owned subsidiaries, and entities more than 50% owned and limited partnerships or LLCs where we, as the general partner or managing member, exercise effective control, even though our ownership is less than 50%. The related agreements provide us with broad powers. The other parties do not participate in the management of the entity and do not have the substantial ability to remove us. Investment in entities in which our investment is less than 50% ownership and we do not have significant control are accounted for by the equity method if ownership is between 20%–50%, or by the cost method if ownership is less than 20%. We have reviewed each of the underlying agreements and determined we have effective control; however, if it was determined this control did not exist, these investments would be reflected on the equity method of accounting. Although this would change individual line items within our consolidated financial statements, it would have no effect on our net income and/or total stockholders’ equity.
Year ended December 31, 2007 compared to the year ended December 31, 2006
Our total revenues decreased $2,473,000 (2%) as compared to 2006. Revenues from our urology services decreased $529,000 (0.4%) as compared to 2006. Revenues from our lithotripsy business decreased $1,694,000 in 2007 as compared to 2006, while revenues from our prostate business increased $1,165,000 in 2007 as compared to 2006. The actual number of lithotripsy procedures performed in 2007 decreased by 5% compared to 2006, primarily due to partnership and mobile route closures in late 2006 and continued weak performance across our western region partnerships in early 2007. The average rate per procedure increased by 3% in 2007 as compared to 2006. Revenues for our medical products segment decreased by $1,979,000 (10%) compared to 2006 primarily due to less sales of our lithotripters and the discontinuation of sales of certain tables in early 2007. Medical products revenues before intersegment eliminations totaled $26.1 million for 2007 and $28.4 million for 2006. We sold 8 lithotripters and 28 tables in 2007 compared to 17 lithotripters and 100 tables in 2006. Revenues from our service operations and consumable sales decreased $2,173,000 in 2007 as compared to 2006. This decrease relates primarily to lower electrode sales especially as related to our foreign operations which we closed in 2006. Revenues from our new laboratory which commenced operations in January 2006, totaled $3,418,000 and $1,138,000 for the years ended December 31, 2007 and 2006, respectively.
Our costs of services and general and administrative expenses for 2007 decreased $7,726,000 (6%) compared to 2006. Our cost of services associated with our urology services operations increased $2,228,000 (4%) in 2007 as compared with 2006. The cause of this increase relates primarily to increased rental expenses paid on Revolix units leased from our medical products division of $1,500,000 and a decrease in gains resulting from sales of various partnership interests in 2007 as compared to 2006 of $969,000 which are recorded against operating expenses. This was partially offset by lower laser supply costs of $1,087,000, which corresponds to more partnerships utilizing the Revolix laser as compared to the greenlight laser. Our cost of services associated with our medical products operations for 2007 decreased $5,572,000 (33%) compared to 2006. The primary cause of this decrease relates to significant decreases in external sales of lithotripters and tables in 2007, a cost reduction recorded as a result of the receipt of lease payments from our urology services division on Revolix units noted above, partially offset by approximately $900,000 in increased expenses at our new lab. A significant portion of medical products costs relate to providing maintenance services to our urology services segment and are allocated to the urology services segment. In the future we expect margins in medical products to continue to vary significantly from period to period based on the mix of intercompany and third-party sales. Our selling, general and administrative costs decreased $4,414,000 (22%) in 2007 as compared to 2006. This is primarily attributable to approximately $1,850,000 in costs paid to strategic consultants, $1 million in severance payments, $500,000 in higher share based compensation costs which were incurred in 2006 compared to 2007, as well as approximately $516,000 in decreased personnel, insurance, marketing, recruiting and other costs. In addition we received approximately $900,000 as a result of our former Swiss manufacturing subsidiary’s insolvency proceedings in 2007, which was recorded against selling, general and administrative expenses. |
