PART I
ITEM 1.
BUSINESS
GENERAL
American Shared Hospital Services (“ASHS” and, together with its subsidiaries, the “Company”) provides Gamma Knife stereotactic radiosurgery services to twenty-one (21) medical centers in eighteen (18) states. The Company provides these services through its 81% indirect interest in GK Financing, LLC, a California limited liability company (“GKF”). The remaining 19% of GKF is owned by GKV Investments, Inc., a wholly owned U.S. subsidiary of Elekta AG, a Swedish company (“Elekta”). Elekta is the manufacturer of the Leksell Gamma Knifeâ (the “Gamma Knife”). GKF is a non-exclusive provider of alternative financing services for Elekta Gamma Knife units in the United States and Brazil. Gamma Knife services accounted for 100% of the Company’s revenue in 2006.
In April 2006, the Company invested $2,000,000 for a minority equity interest in Still River Systems, Inc. (“Still River”), a development-stage company based in Littleton, Massachusetts, which in collaboration with scientists from MIT’s Plasma Science and Fusion Center, is developing a medical device for the treatment of cancer patients using proton beam radiation therapy (PBRT). The Company has spent an additional $2,000,000 for the right to purchase two Clinatron 250™ PBRT systems from Still River for anticipated delivery in 2009. The Still River PBRT systems are not currently FDA approved.
The Company is also currently in the process of installing an Image Guided Radiation Therapy (IGRT) system and related equipment at one of its existing Gamma Knife sites which is expected to become operational in late 2007.
The Company continues to develop its design and business model for “The Operating Room for the 21st Century”â (“OR21”â). OR21 is not expected to generate significant revenue within the next twelve months.
The Company was incorporated in the State of California in 1983 and its predecessor, Ernest A. Bates, M.D., Ltd. (d/b/a American Shared Hospital Services), a California limited partnership, was formed in June 1980.
GAMMA KNIFE OPERATIONS
Gamma Knife stereotactic radiosurgery, a non-invasive procedure, is an alternative to conventional brain surgery or can be an adjunct to conventional brain surgery. Compared to conventional surgery, Gamma Knife surgery usually involves shorter patient hospitalization, lower risk of complications and can be provided at a lower cost. Typically, Gamma Knife patients resume their pre-surgical activities one or two days after treatment. The Gamma Knife treats patients with 201 single doses of gamma rays that are focused with great precision on

small and medium size, well circumscribed and critically located structures in the brain. During 2006 Elekta introduced a new Gamma Knife model, the Perfexion™ unit (“Perfexion”), which treats patients with 192 single doses of gamma rays and also provides the ability to perform procedures on areas of the cervical spine. The Gamma Knife delivers the concentrated dose of gamma rays from Cobalt-60 sources housed in the Gamma Knife. The Cobalt-60 sources converge at the target area and deliver a dose that is high enough to destroy the diseased tissue without damaging surrounding healthy tissue.
The Gamma Knife treats selected malignant brain tumors, benign brain tumors, trigeminal neuralgia (facial pain) and arteriovenous malformations. Research is being conducted to determine whether the Gamma Knife can be effective in the treatment of epilepsy and other functional disorders.
As of December 31, 2006, the Company estimates that there were 111 Gamma Knife sites in the United States and 248 units in operation worldwide. An estimated percentage breakdown of Gamma Knife procedures performed in the U.S. by indications treated is as follows: malignant (45%) and benign (29%) brain tumors, functional disorders (15%) and vascular disorders (11%).
The Company, as of March 9, 2007, has twenty-one (21) Gamma Knife units operating at twenty-one (21) sites in the United States. The Company’s first Gamma Knife commenced operation in September 1991. The Company’s Gamma Knife units performed approximately 2,600 procedures in 2006 for a cumulative total of approximately 17,000 procedures through December 31, 2006.
Gamma Knife revenue for the Company during the five (5) years ended December 31, and the percentage of total revenue of the Company represented by the Gamma Knife for each of the last five years, are set forth below:
                 
Year Ended   Total Gamma Knife   Gamma Knife/
December 31,   Revenue (in thousands)   Total Revenue
2006
  $ 20,385       100.0 %
2005
  $ 18,231       100.0 %
2004
  $ 16,389       100.0 %
2003
  $ 16,178       100.0 %
2002
  $ 13,366       100.0 %
The Company conducts its Gamma Knife business through its 81% indirect interest in GKF. The remaining 19% interest is indirectly owned by Elekta. GKF, formed in October 1995, is managed by its policy committee. The policy committee is composed of one representative from the Company, Ernest A. Bates, M.D., ASHS’s Chairman and CEO, and one representative from Elekta. The policy committee sets the operating policy for GKF. The policy committee may act only with the unanimous approval of both of its members. The policy committee selects a manager to handle GKF’s daily operations. Craig K. Tagawa, Chief Executive Officer of GKF and Chief Operating and Financial Officer of ASHS, serves as GKF’s manager.

GKF’s profits and/or losses and any cash distributions are allocated based on membership interests. GKF’s Operating Agreement requires that it have a cash reserve of at least $50,000 before cash distributions are made to its members. From inception to December 31, 2006, GKF has distributed $20,412,000 to the Company and $4,788,000 to the minority partner.

CUSTOMERS
The Company’s current business is the outsourcing of Gamma Knife stereotactic radiosurgery services. The Company typically provides the Gamma Knife equipment, as well as planning, installation, reimbursement and marketing support services. The majority of the Company’s customers pay the Company on a fee per use basis. The market for these services primarily consists of major urban medical centers. The Gamma Knife business is capital intensive. The total cost of a Gamma Knife facility usually ranges from $3 million to $5.5 million, including equipment, site construction and installation. The Company pays for the Gamma Knife and the medical center generally pays for site and installation costs. The following is a listing of the Company’s current sites as of March 9, 2007:

Table of Contents

The Company currently has no Gamma Knife sites under development, but has a contract to provide IGRT and related equipment services to an existing Gamma Knife customer under a revenue sharing agreement. This site is expected to begin operation in late 2007. One of the Company’s existing Gamma Knife contracts is scheduled to terminate in fall 2007 at the end of its term. Another contract is scheduled to terminate in early 2008 at the end of its term.
The Company’s fee per use agreement is typically for a ten-year term. The fixed fee per use reimbursement amount that the Company receives from the customer is based on the Company’s cost to provide the service and the anticipated volume of the customer. The contracts signed by the Company typically call for a fee ranging from $7,500 to $9,000 per procedure. There are no minimum volume guarantees required of the customer. Typically, GKF is responsible for providing the Gamma Knife and related ongoing Gamma Knife equipment expenses (i.e., personal property taxes, insurance, and equipment maintenance) and also helps fund the customer’s Gamma Knife marketing. The customer generally is obligated to pay site and installation costs and the costs of operating the Gamma Knife. The customer can either renew the agreement or terminate the agreement at the end of the contractual term. If the customer chooses to terminate the agreement, then GKF removes the equipment from the medical center for possible placement at another site.
The Company’s revenue sharing agreements (“retail”) are for a period of eight to fifteen years. Instead of receiving a fixed fee, the Company receives all or a percentage of the reimbursement (exclusive of physician fees) received by the customer less the operating expenses of the Gamma Knife. The Company is at risk for any reimbursement rate changes for Gamma Knife services by the government or other third party payors. The Company is also at risk if the customer inefficiently operates the Gamma Knife. There are no minimum volume guarantees required of the customer.
One customer accounted for approximately 13% of the Company’s revenue in 2006. No one individual customer accounted for more than 10% of the Company’s revenue in either 2005 or 2004.
MARKETING
The Company markets its services through its preferred provider status with Elekta and a direct sales effort. From April 2003 to March 2004, the direct sales effort was executed by the Company’s Chief Executive and Chief Operating Officers. Since March 2004, the Company has had a Director of Sales to lead the direct sales effort, and in January 2007 the Company hired a Vice President of Sales and Business Development. The major advantages to a health care provider in contracting with the Company for Gamma Knife services include:
§   The medical center avoids the high cost of owning the equipment. By not acquiring the Gamma Knife unit, the medical center is able to allocate the funds otherwise required to purchase and/or finance the Gamma Knife to other projects.

Table of Contents

§   The medical center avoids the risk of Gamma Knife under-utilization. The Company does not have minimum volume requirements. The medical center pays the Company only for each Gamma Knife procedure performed on a patient.
 
§   The medical center transfers the risk of technological obsolescence to the Company. The medical center and its physicians are not under any obligation to utilize technologically obsolete equipment.
 
§   The Company provides planning, installation, operating and marketing assistance and support to its Gamma Knife customers.
FINANCING
The Company’s Gamma Knife business is operated through GKF. Through 2003, GKF funded its existing Gamma Knife units with loans from a single lender, DVI Financial Services Inc. (“DVI”), for 100% of the cost of each Gamma Knife, plus any sales tax, customs and duties. Since 2004, alternative lenders have been utilized for financing the Company’s Gamma Knife unit additions and upgrades. The loans are predominantly fully amortized over an 84-month period. The loans are collateralized by the Gamma Knife, customer contracts and accounts receivable, and are without recourse to the Company and Elekta.
DVI filed for Chapter 11 bankruptcy protection during 2003, and all the Company’s loans with DVI were subsequently assumed by another lender as successor servicer. The Company continues to make payments to the successor servicer on these outstanding note balances. Management believes that the bankruptcy of DVI has not had a materially adverse effect on the Company’s financial position or results of operations.
COMPETITION
Conventional neurosurgery is the primary competitor of Gamma Knife radiosurgery. Gamma Knife surgery has gained acceptance as an alternative and/or adjunct to conventional surgery due to its more favorable morbidity outcomes for certain procedures as well as its non-invasiveness. Utilization of the Company’s Gamma Knife units is contingent on the acceptance of Gamma Knife radiosurgery by the customer’s neurosurgeons, radiation oncologists and referring physicians. In addition, the utilization of the Company’s Gamma Knife units is impacted by the proximity of competing Gamma Knife centers and providers using other radiosurgery devices.
The Company’s ability to secure additional customers for Gamma Knife services is dependent on its ability to effectively compete against (i) Elekta, the manufacturer of the Gamma Knife, (ii) manufacturers of other radiosurgery devices, and (iii) other companies that outsource Gamma Knife services. The Company does not have an exclusive relationship with Elekta and has previously lost sales to customers that chose to purchase a Gamma Knife directly from Elekta. The Company may continue to lose future sales to such customers and may also lose sales to the Company’s competitors.

GOVERNMENT REGULATION
The Company’s Gamma Knife customers receive payments for patient care from federal government and private insurer reimbursement programs. Currently in the United States, Gamma Knife services are performed on an in-patient and on an out-patient basis. Gamma Knife patients with Medicare as their primary insurer and treated on either an in-patient or out-patient basis, comprise an estimated 20% to 35% of the total Gamma Knife patients treated.
A Prospective Payment System (“PPS”) is utilized to reimburse hospitals for care given to hospital in-patients covered by federally funded reimbursement programs. Patients are classified into a Diagnosis Related Group (“DRG”) in accordance with the patient’s diagnosis, necessary medical procedures and other factors. Patient reimbursement is limited to a predetermined amount for each DRG. The reimbursement payment may not necessarily cover the cost of all medical services actually provided because the payment is predetermined. Effective October 1, 1997, Gamma Knife services for Medicare hospital in-patients are predominantly reimbursed under either DRG 7 or DRG 8.
In 1986 and again in 1990, Congress enacted legislation requiring the Department of Health and Human Services (“DHHS”) to develop proposals for a PPS for Medicare out-patient services. DHHS proposed a new payment system, Ambulatory Product Classifications (“APC”), which affects all out-patient services performed in a hospital based facility. APC implementation took place in the third quarter of 2000.
The APC consists of 346 clinically, homogenous classifications or groupings of codes that are typically used in out-patient billing. Out-patient services are bundled with fixed rates of payment determined according to specific regional and national factors, similar to that of the in-patient PPS.
The Gamma Knife APC rate is modified periodically but the total reimbursement amount has remained fairly constant. However, effective January 1, 2007 the Medicare outpatient reimbursement rate for Gamma Knife procedures was increased approximately 24% compared to the 2006 rate of reimbursement. On January 1, 2006 this rate was increased approximately 28% compared to the 2005 rate. The Company has four contracts from which its revenue is directly affected by changes in payment rates under the APC system.
The payment of remuneration to induce the referral of health care business has been a subject of increasing governmental and regulatory focus in recent years. Section 1128B(b) of the Social Security Act (sometimes referred to as the “federal anti-kickback statute”) provides criminal penalties for individuals or entities that knowingly and willfully offer, pay, solicit or receive remuneration in order to induce referrals for items or services for which payment may be made under the Medicare and Medicaid programs and certain other government funded programs. The Social Security Act provides authority to the Office of Inspector General through civil proceedings to exclude an individual or entity from participation in the Medicare and state health programs if it is determined any such party has violated Section 1128B(b) of the Social Security

Table of Contents

Act. The Company believes that it is in compliance with the federal anti-kickback statute. Additionally, the Omnibus Budget Reconciliation Act of 1993, often referred to as “Stark II”, bans physician self-referrals to providers of designated health services with which the physician has a financial relationship. The term “designated health services” includes, among others, radiation therapy services and in-patient and out-patient hospital services. On January 1, 1995, the Physician Ownership and Referral Act of 1993 became effective in California. This legislation prohibits physician self-referrals for covered goods and services, including radiation oncology, if the physician (or the physician’s immediate family) concurrently has a financial interest in the entity receiving the referral. The Company believes that it is in compliance with these rules and regulations.
A range of federal civil and criminal laws target false claims and fraudulent billing activities. One of the most significant is the Federal False Claims Act, which prohibits the submission of a false claim or the making of a false record or statement in order to secure a reimbursement from a government-sponsored program. In recent years, the federal government has launched several initiatives aimed at uncovering practices which violate false claims or fraudulent billing laws. Claims under these laws may be brought either by the government or by private individuals on behalf of the government, through a “whistleblower” or “qui tam” action. The Company believes that it is in compliance with the Federal False Claims Act; however, because such actions are filed under seal and may remain secret for years, there can be no assurance that the Company or one of its affiliates is not named in a material qui tam action.
Legislation in various jurisdictions requires that health facilities obtain a Certificate of Need (“CON”) prior to making expenditures for medical technology in excess of specified amounts. Four of the Company’s existing customers were required to obtain a CON or its equivalent. The CON procedure can be expensive and time consuming and may impact the length of time before Gamma Knife services commence. CON requirements vary from state to state in their application to the operations of both the Company and its customers. In some jurisdictions the Company is required to comply with CON procedures to provide its services and in other jurisdictions customers must comply with CON procedures before using the Company’s services.
The Company’s Gamma Knife units contain Cobalt 60 radioactive sources. The medical centers that house the Company’s Gamma Knife units are responsible for obtaining possession and user’s licenses for the Cobalt 60 source.
The Company believes it is in substantial compliance with the various rules and regulations that affect its businesses.
INSURANCE AND INDEMNIFICATION
The Company’s contracts with equipment vendors generally do not contain indemnification provisions. The Company maintains a comprehensive insurance program covering the value of its property and equipment, subject to deductibles, which the Company believes are reasonable.
The Company’s customer contracts generally contain mutual indemnification provisions. The Company maintains general and professional liability insurance. The Company is not involved

in the practice of medicine and therefore believes its present insurance coverage and indemnification agreements are adequate for its business.
PROTON BEAM RADIATION THERAPY (PBRT) BUSINESS
Proton beam radiation therapy is an alternative to traditional external beam, photon based radiation delivered by linear accelerators. PBRT, first clinically introduced in the 1950’s, has physics advantages compared to photon based systems which allow PBRT to deliver higher radiation doses to the tumor with less radiation to healthy tissue. PBRT currently treats prostate, eye, cranial-spinal, head & neck, lung, liver and breast tumors. In excess of 55,000 patients have been treated with protons worldwide.
Introduction of PBRT in the United States, until recently, has been limited due to lack of adequate reimbursement and the high capital costs of these projects. The Company believes that the current development of one and two treatment room PBRT systems at lower capital costs, and recent implementation of appropriate reimbursement levels from the Centers for Medicare and Medicaid Services (“CMS”) will help make this technology available to a larger segment of the market. CMS PBRT reimbursement in 2007 increased approximately 20% over 2006 reimbursement levels.
There are several competing manufacturers of proton beam systems, including Still River, IBA Particle Therapy Inc., Hitachi Ltd., Optivus Proton Therapy Inc., Varian Medical Systems, Inc. (Accel) and Mitsubishi Electric. The Company has invested in Still River and has made deposits towards the purchase of two Still River Clinatron 250™ systems. The Still River system potentially provides cancer centers the opportunity to introduce single treatment room PBRT services for approximately $20 million rather than four and five PBRT treatment room programs costing in excess of $100 million. The Still River system is not yet FDA approved and there can be no assurance that it will be approved.
The Company believes the business model it has developed for use in its Gamma Knife business can be tailored for the PBRT market segment. The Company is targeting large, hospital based cancer programs. The Company’s ability to develop a successful PBRT financing entity depends on the decision of cancer centers to self fund or to fund the PBRT through conventional financing vehicles, the Company’s ability to capture market share from competing alternative PBRT financing entities, and the Company’s ability to raise capital to fund PBRT projects.
EMPLOYEES
At December 31, 2006, the Company employed twelve (12) people on a full-time basis. None of these employees is subject to a collective bargaining agreement and there is no union representation within the Company. The Company maintains various employee benefit plans and believes that its employee relations are good.

RISK FACTORS
In addition to the other information in this report, the following factors could affect our future business, results of operations, cash flows or financial position, and could cause future results to differ materially from those expressed in any of the forward-looking statements contained in this report.
The Company’s Capital Investment in Each Gamma Knife Unit is Substantial
Each Gamma Knife unit requires a substantial capital investment. In some cases, we contribute additional funds for capital costs and/or annual operating and equipment related costs such as marketing, maintenance, insurance and property taxes. Due to the structure of our contracts with medical centers, there can be no assurance that these costs will be fully recovered or that we will earn a satisfactory return on our investment.
The Market for the Gamma Knife is Limited
There is a limited market for the Gamma Knife, and the market may be mature. The Company has not entered into a Gamma Knife contract at a new site since 2004. Due to the substantial costs of acquiring a Gamma Knife unit, we must identify medical centers that possess neurosurgery and radiation oncology departments capable of performing a large number of Gamma Knife procedures. As of December 31, 2006 there were approximately 111 operating Gamma Knife units in the United States, of which 21 units are owned by us, and approximately 248 units in operation worldwide. There can be no assurance that we will be successful in placing additional units at any sites in the future. The Company’s existing contracts with its customers are fixed in length and there can be no assurance that the customers will wish to extend the contract beyond the end of the term.
The Company Has a High Level of Debt
The Company’s business is capital intensive. The Company finances its Gamma Knife units primarily through its GKF subsidiary, and these amounts have been generally non-recourse to ASHS. The combined long term debt and present value of capital leases totals $21,082,000 and is collateralized by the Gamma Knife units and other assets, including accounts receivable and future proceeds from any contract between the Company and any end user of the financed equipment. This high level of debt may adversely affect the Company’s ability to secure additional credit in the future, and as a result may affect operations and profitability. If default on debt occurs in the future, the Company’s creditors would have the ability to accelerate the

defaulted loan, to seize the Gamma Knife unit or other equipment with respect to which default has occurred, and to apply any collateral they may have at the time to cure the default. The Company also has a line of credit with a bank, against which it has drawn $4,000,000 as of December 31, 2006.
The Market is Competitive
There are currently three companies (in addition to our company) that actively provide alternative, non-conventional Gamma Knife financing to potential customers. We believe there are no competitor companies that currently have more than six Gamma Knife units in operation. The Company’s relationship with Elekta, the manufacturer of the Leksell Gamma Knife unit, is non-exclusive, and in the past the Company has lost sales to customers that chose to purchase a Gamma Knife unit directly from Elekta. In addition, the Company may continue to lose future sales to such customers and may also lose future sales to its competitors. There can be no assurance that the Company will be able to successfully compete against others in placing future units.
There Are Alternatives to the Gamma Knife
There are other radiosurgery devices as well as conventional neurosurgery that compete against the Gamma Knife. Each of the medical centers targeted by the Company could decide to acquire another radiosurgery device instead of a Gamma Knife. In addition, neurosurgeons who are primarily responsible for referring patients for Gamma Knife surgery may not be willing to make such referrals for various reasons, instead opting for invasive surgery. There can be no assurance that the Company will be able to secure a sufficient number of future sites or Gamma Knife procedures to sustain its profitability and growth.
The Company’s Revenue Could Decline if Federal Reimbursement Rates are Lowered
The amount reimbursed to medical centers for each Gamma Knife treatment may decline in the future. The reimbursement decrease may come from federally mandated programs (i.e., Medicare and Medicaid) or other third party payor groups. Sixteen of the Company’s existing contracts are reimbursed by the medical center to the Company on a fee per use basis. The primary risk under this type of contract is that the actual volume of procedures could be less than projected. However, a significant reimbursement rate reduction may result in the Company restructuring certain of its existing contracts. There are also five contracts where the Company receives revenue based directly on the amount of reimbursement received for procedures performed. Revenue under those contracts and any future contracts with revenue based directly on reimbursement amounts will be impacted by any reimbursement rate change. Some of the Company’s future contracts for Gamma Knife services may have revenue based on such reimbursement rates instead of a fee for service basis. There can be no assurance that future changes in healthcare regulations and reimbursement rates will not directly or indirectly adversely affect the Company’s Gamma Knife revenue.
New Technology and Products Could Result in Equipment Obsolescence
There is constant change and innovation in the market for highly sophisticated medical equipment. New and improved medical equipment can be introduced that could make the Gamma Knife technology obsolete and that would make it uneconomical to operate. During 2000, Elekta introduced an upgraded Gamma Knife which costs approximately $3.6 million plus

13


Table of Contents

applicable tax and duties. This upgrade includes an Automatic Positioning System™ (“APS”), and therefore involves less health care provider intervention. In early 2005, Elekta introduced a new upgrade, the model 4C. Twelve of our existing Gamma Knife units include APS and eight of our existing Gamma Knife units are upgradeable. The cost to upgrade existing units to the new model 4C Gamma Knife with APS is estimated to be approximately $200,000 to $1,000,000, depending on the current Gamma Knife configuration. In 2006 Elekta introduced a new model of the Gamma Knife, the Perfexion, which costs approximately $4.5 million plus applicable taxes and duties. The Perfexion can perform procedures faster than previous Gamma Knife models and also provides the ability to perform procedures on areas of the cervical spine. Existing models of the Gamma Knife are not upgradeable to the Perfexion model. The failure to acquire or use new technology and products could have a material adverse effect on our business and results of operations.
The Company has Invested in a Proton Beam Business that is Developmental and Unproven
We have committed a substantial amount of money to next-generation proton beam technology. The PBRT system being developed by Still River is not commercially proven and cannot be sold or used prior to FDA approval, which may not be obtained until 2009, if at all. Prior to that time, we must make progress payments of $6,000,000 for two Clinatron 250™ systems (The Company has already made deposits of $2,000,000 towards this commitment). There can be no assurance that we will recover this investment, or our $2,000,000 minority investment in Still River. We are unable to enter into firm agreements with hospitals for PBRT systems that we are obligated to purchase. Our current belief is that we will begin to receive revenue for PBRT systems placed and financed by us no earlier than 2010.

The Board of Directors authorized in March 1999 the repurchase of up to 500,000 shares of the Company’s Common Stock in the open market from time to time at prevailing prices. Approximately 484,000 shares have been repurchased in the open market pursuant to that authorization at a cost of approximately $1,213,000, although no shares have been repurchased in the open market since 2001. The Board of Directors on February 2, 2001 authorized the repurchase of up to another 500,000 shares of the Company’s common stock in the open market from time to time at prevailing prices. No shares have been repurchased under this additional authorization.
During 2006 holders of options to acquire the Company’s common stock exercised their respective rights pursuant to such securities, resulting in the Company issuing 4,000 new shares of common stock for approximately $5,000.
On March 22, 1999 the Company adopted a Shareholder Rights Plan (“Plan”). Under the Plan, the Company made a dividend distribution of one Right for each outstanding share of the Company’s common stock as of the close of business on April 1, 1999. The Rights become exercisable only if any person or group, with certain exceptions, becomes an “acquiring person” (acquires 15 percent or more of the Company’s outstanding common stock) or announces a tender or exchange offer to acquire 15 percent or more of the Company’s outstanding common stock. The Company’s Board of Directors adopted the Plan to protect shareholders against a coercive or inadequate takeover offer. The Board of Directors is not aware that any person or group intends to make a takeover offer for the Company.
At December 31, 2006 the Company had 5,023,418 issued and outstanding common shares, 149,180 common shares reserved for options, 2,000 restricted stock units issued and 5,175 shares reserved pursuant to the Company’s Shareholder Rights Plan.
In fourth quarter 2006, the Board of Directors declared a quarterly dividend of $.0475 per common share to shareholders of record on January 2, 2007, paid on January 15, 2007. During 2006, shareholders of record as of January 3, 2006, April 3, 2006, July 3, 2006 and October 2, 2006 were paid quarterly dividends of $0.0475 per common share on January 18, 2006, April 17, 2006, July 14, 2006 and October 16, 2006. During 2005, shareholders of record as of January 3, 2005, April 4, 2005, July 1, 2005 and October 3, 2005 were paid quarterly dividends respectively as follows: $0.045 on January 14, 2005 and April 15, 2005, and $0.0475 on July 15, 2005 and October 17, 2005. The Board of Directors evaluates the Company’s level of earnings, balance sheet position, availability of cash and expected future cash requirements on a quarterly basis to determine its dividend policy. The Company did not pay cash dividends prior to 2001.

This financial data as of December 31, 2006, 2005 and 2004 and for the years ended December 31, 2006, 2005 and 2004 should be read in conjunction with our consolidated financial statements and the notes thereto beginning on page A-1 of this report and with Item 7–“Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
ITEM 7.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
APPLICATION OF CRITICAL ACCOUNTING POLICIES
The Company’s consolidated financial statements are prepared in accordance with generally accepted accounting principles and follow general practices within the industry in which it operates. Application of these principles requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions and judgments. Certain policies inherently have a greater reliance on the use of estimates, assumptions and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions and judgments are necessary when assets and liabilities are required to be recorded at fair value, when a decline in the value of an asset not carried on the financial statements at fair value warrants an impairment write-down or valuation reserve to be established, or when an asset or liability needs to be recorded contingent upon a future event. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and the information used to record valuation adjustments for certain assets and liabilities are based either on quoted market prices or are provided by other third-party sources when available. When third-party information is not available, valuation adjustments are estimated in good faith by management primarily through the use of internal cash flow modeling techniques.
The most significant accounting policies followed by the Company are presented in Note 2 to the consolidated financial statements. These policies along with the disclosures presented in the other financial statement notes and in this financial review, provide information on how significant assets and liabilities are valued in the financial statements and how those values are determined. Based on the valuation techniques used and the sensitivity of financial statement amounts to the methods, assumptions and estimates underlying those amounts, management has identified the determination of the allowance for doubtful accounts and revenue recognition to be two areas that required the most subjective or complex judgments, and as such could be most subject to revision as new information becomes available. The following are our critical accounting policies in which management’s estimates, assumptions and judgments most directly and materially affect the financial statements:

Revenue Recognition
The Company has only one revenue-generating activity, which is the operation of Gamma Knife units by GK Financing, LLC (“GKF”), an 81% owned subsidiary of the Company.
Revenue is recognized when services have been rendered and collectibility is reasonably assured, on either a fee per use or revenue sharing basis. The Company has contracts with 16 fee per use hospitals and five retail hospitals. Under both of these types of agreements, the hospital is responsible for billing patients and collection of fees for services performed. Revenue associated with installation of the Gamma Knife units, if any, is a part of the negotiated lease amount and not a distinctly identifiable amount. The costs, if any, associated with installation of the units are amortized over the period of the related lease to match revenue recognition of these costs.
For fee per use agreements, revenue is not estimated because these contracts provide for a fixed fee per procedure, and are typically for a ten year term. Revenue is recognized at the time the procedures are performed, based on each hospital’s contracted rate. There is no guaranteed minimum payment. Costs related to operating the units are charged to costs of operations as incurred, which approximates the recognition of the related revenue. Revenues under fee per use agreements are recorded on a gross basis.
GKF has five agreements that are based on revenue sharing. These can be further classified as either “turn-key” arrangements or “net revenue sharing” arrangements. For the four turn-key sites, GKF is solely responsible for the costs to acquire and install the Gamma Knife. In return, GKF receives payment from the hospital in the amount of its reimbursement from third party payors. Revenue is recognized by the Company during the period in which the procedure is performed, and is estimated based on what can be reasonably expected to be paid by the third party payor to the hospital. The estimate is primarily determined from historical experience and hospital contracts with third party payors. These estimates are reviewed on a regular basis and adjusted as necessary to more accurately reflect the expected payment amount. The Company also records an estimate of operating costs associated with each procedure during the period in which the procedure is performed. Costs are determined primarily based on historical treatment protocols and cost schedules with the hospital. The Company’s estimated operating costs are reviewed on a regular basis and adjusted as necessary to more accurately reflect the actual operating costs. Revenue for turn-key sites is recorded on a gross basis, and the operating expenses the Company reimburses to the hospital are recorded in other operating costs.
Under net revenue sharing arrangements the hospital shares in the responsibility and risk with GKF for the capital investment to acquire and install the Gamma Knife. Unlike our turn-key arrangement, GKF’s lease payment under a net revenue sharing arrangement is a percentage of revenue less operating costs. Payments are made by the hospital, generally on a monthly basis, to GKF based on an agreed upon percentage allocation of income remaining after all operating expenses are deducted from cash collected. Revenue is recognized during the period in which the procedure is performed, and is determined based on the net reimbursement amount that GKF expects to receive from the hospital for each Gamma Knife procedure. Under the net revenue sharing arrangement, the percent of revenue received by GKF is recorded net of costs to provide a Gamma Knife treatment. This estimate is reviewed on a regular basis and adjusted as necessary to more accurately reflect the expected payment amount.

Table of Contents

Revenue from retail arrangements amounted to approximately 34%, 29% and 25% of revenue for the years ended December 31 2006, 2005 and 2004, respectively.
Allowance for Doubtful Accounts
The allowance for doubtful accounts is estimated based on possible losses relating to the Company’s revenue sharing customers. The Company receives reimbursement from the customer based on the customer’s collections from individuals and third-party payors such as insurance companies and Medicare. Receivables are charged against the allowance in the period that they are deemed uncollectible.
If the Company’s net accounts receivable estimates for revenue sharing customers as of December 31, 2006 changed by as much as 10% based on actual collection information, it would have the effect of increasing or decreasing revenue by approximately $235,000.
GENERAL
During the years ended December 31, 2006, 2005 and 2004, 100% of the Company’s medical services revenue was derived from its Gamma Knife business.
TOTAL REVENUE
                                         
            Increase           Increase    
    2006   (Decrease)   2005   (Decrease)   2004
Medical services revenue (in thousands)
  $ 20,385       11.8 %   $ 18,231       11.2 %   $ 16,389  
Number of Gamma Knife procedures
    2,563       6.3 %     2,410       12.6 %     2,140  
Average revenue per procedure
  $ 7,954       5.1 %   $ 7,565       (1.2 )%   $ 7,658  
Gamma Knife revenue increased $2,154,000 and $1,842,000 in 2006 and 2005, respectively, compared to the prior years. The 2006 increase compared to 2005 was primarily due to the full year inclusion of three new Gamma Knife units that began operation during 2005 and an increase in the average revenue per procedure, primarily at some of the Company’s revenue sharing sites. The 2005 increase was due to three new Gamma Knife units that began operation during 2005 and the full year inclusion of one new Gamma Knife unit that began operation during 2004, which offset a 4% decrease in revenue from Gamma Knife units in operation more than one year. The Company had twenty-one, twenty-one and eighteen Gamma Knife units in operation at December 31, 2006, 2005 and 2004, respectively.
The number of Gamma Knife procedures in 2006 increased by 153 compared to 2005 primarily due to the full year inclusion of three Gamma Knife units that began operation during 2005 and a 2% increase in procedures from Gamma Knife units in operation more than one year. The number of Gamma Knife procedures in 2005 increased by 270 compared to 2004 due to the

21


Table of Contents

increase in the number of Gamma Knife units in operation, as well as a 3% increase in procedures from Gamma Knife units in operation more than one year.
Revenue per procedure increased $389 in 2006 and decreased $93 in 2005 compared to the prior years. The Company’s contracts generally have different procedure rates because their investment basis varies, so revenue per procedure can vary year to year depending primarily on the mix of procedures performed at certain locations. The increase per procedure in 2006 was primarily due to higher average procedure rates at the Company’s turn-key retail sites and a higher mix of revenue generated by the retail sites compared to fee per use sites. The decrease in 2005 was primarily due to lower average procedure rates collected at two of the Company’s retail sites.

Percentage of revenue
    50.8 %             49.8 %             48.1 %
The Company’s costs of operations, consisting of maintenance and supplies, depreciation and amortization, and other operating expenses (such as insurance, property taxes, sales taxes, marketing costs and operating costs from the Company’s retail sites) increased $1,293,000 in 2006 compared to 2005, and increased $1,185,000 in 2005 compared to 2004.
The Company’s maintenance and supplies costs were 6%, 6% and 5% of medical service revenue in 2006, 2005 and 2004, respectively. Maintenance and supplies costs increased $260,000 in 2006 compared to 2005, and increased $150,000 in 2005 compared to 2004. The increase in 2006 compared to 2005 was primarily due to the expiration of the warranty period on three Gamma Knife units and the full year inclusion of one Gamma Knife unit where the warranty period expired during 2005. The increase in 2005 compared to 2004 was primarily due to the expiration of the warranty period on one Gamma Knife unit and the full year inclusion of maintenance on two Gamma Knife units where the warranty period expired during the previous year.
Depreciation and amortization increased $470,000 in 2006 compared to 2005, and increased $593,000 in 2005 compared to 2004. The increase in 2006 was primarily due to the full year’s inclusion of depreciation from three Gamma Knife units that started operation during 2005, and the upgrade and/or cobalt reload on two existing Gamma Knife units in 2006. The increase in 2005 was primarily due to the addition of three new Gamma Knife units that commenced operation during first, second and third quarters of 2005 and a full year of depreciation on one new Gamma Knife unit that started operation during 2004.
Other direct operating costs as a percentage of medical services revenue were 16%, 14% and 13% in 2006, 2005 and 2004, respectively. The increase of $563,000 in 2006 compared to 2005 was primarily due to higher operating costs related to an increase in the number of procedures performed at two of the Company’s turn-key retail locations. The increase of $442,000 in 2005

Table of Contents

compared to 2004 was primarily due to increased operating costs related to the Company’s two additional retail Gamma Knife units that started operation during 2005 and higher insurance costs due to additional Gamma Knife units in operation, which were partially offset by lower marketing and promotion costs.

The Company’s selling and administrative costs increased $382,000 in 2006 compared to 2005, and increased $650,000 in 2005 compared to 2004. The increase in 2006 compared to 2005 was due to increased legal, accounting and consulting fees of approximately $234,000 and payroll related costs of approximately $346,000, primarily bonuses paid for the development of the proton beam business. These increases were partially offset by lower business meeting and other business development costs. Costs to develop the Company’s OR21 business decreased $82,000, and there was no Gamma Knife User’s Meeting in 2006, unlike 2005 when the Company spent $42,000 for its second meeting. The increase in 2005 compared to 2004 was primarily due to increased payroll and business development costs of approximately $441,000, which included costs of the Company’s second Gamma Knife User’s Meeting of approximately $42,000 and OR21 business development costs of approximately $151,000. In addition, legal, accounting and consulting fees increased approximately $119,000 and contributions increased approximately $55,000 over the prior year.

The Company’s interest expense increased $86,000 in 2006 compared to 2005, and decreased $186,000 in 2005 compared to 2004. The increase in 2006 was primarily due to interest expense from borrowing under the Company’s line of credit with a bank which offset lower interest expense from financing on the Company’s Gamma Knife units. The decrease in 2005 was due to lower interest expense on the Company’s more mature Gamma Knife units and the completion of debt service on two Gamma Knife units. This was partially offset by additional interest expense on the financing of the Company’s three new Gamma Knife units that started operation during 2005, and the refinancing of one Gamma Knife unit that had previously been paid off. Interest expense on the more mature units is lower than newer units because interest expense decreases with each principal payment.

Interest and other income increased $106,000 in 2006 compared to 2005 and increased $100,000 in 2005 compared to 2004. The increases in both 2006 and 2005 were primarily due to investment in longer term holdings with higher interest rates available compared to prior years.
Minority interest increased $188,000 in 2006 and $143,000 in 2005 compared to the prior year, respectively. Minority interest represents the pre-tax income earned by the minority partner’s 19% interest in GKF. The increase in minority interest reflects the increased profitability of GKF.

Income tax expense increased $422,000 in 2006 compared to 2005, and increased $368,000 in 2005 compared to 2004. The Company recorded an estimated 42% effective income tax provision for 2006, a 5% increase over the estimated income tax provision for 2005. The increase is primarily due to an increase in estimated state income taxes in those states where separate state returns are required and net operating loss carryforwards cannot be applied. The Company’s estimated 37% income tax provision for 2005 was reduced to an effective rate of 31% by a $193,000 income tax benefit from the exercise of options to purchase 264,000 common shares. The Company’s estimated 40% income tax provision for 2004 was reduced to an effective rate of approximately 17% by a $547,000 income tax benefit from the exercise of options to purchase 846,000 common shares. The income tax benefits are a result of compensation expense that was recognized when these options for common shares were granted in 1995.
The Company anticipates that it will continue to record income tax expense if it operates profitably in the future. Currently there are state income tax payments required for most states.

However there are minimal federal income tax payments required due to net operating loss carryforwards and other deferred tax assets available for tax purposes.
The Company had a net operating loss carryforward for federal income tax return purposes at December 31, 2006 of approximately $9,498,000.

The Company had net income of $1,656,000 in 2006 compared to $1,767,000 in 2005 and $1,985,000 in 2004. Net income for 2006 included increased operating income of $393,000, an 11.3% increase compared to 2005, which was generated primarily by a revenue increase of 11.8%. An increase of $422,000 in the income tax provision for 2006 compared to 2005 more than offset the operating income increase, causing a decrease in net income of $111,000. Net income for 2005 included increased operating income of $193,000 compared to 2004, which was primarily due to the addition of three new Gamma Knife units during 2005. This was offset by an increase in income tax expense of $368,000 due to reduced income tax benefits available on the exercise of options to purchase common stock.
LIQUIDITY AND CAPITAL RESOURCES
The Company had cash and cash equivalents of $3,952,000 at December 31, 2006 compared to $1,298,000 at December 31, 2005. The increase in cash resulted primarily from a $2,953,000 reduction in short term securities as of December 31, 2006 compared to the prior year. The Company’s expected primary cash needs on both a short and long-term basis are for capital expenditures, business expansion, working capital, payment of quarterly dividends and other general corporate purposes.
Securities represents a portion of the Company’s cash that is invested in high-quality short to long-term fixed income marketable securities in order to maximize income on its available cash. Securities with maturity dates between three and twelve months in the amount of $1,574,000 are classified as current assets. Securities in the amount of $3,380,000 have maturities in excess of one year and are classified as long-term. It is the Company’s intent to hold these securities until maturity.
Restricted cash of $50,000 at December 31, 2006 reflects cash that may only be used for the operations of GKF.
The Company has a $6,000,000 line of credit with a bank, secured by its cash and securities. The line of credit has been in place since June 2004 and is renewable annually. As of December

25


Table of Contents

31, 2006, there was $4,000,000 borrowed against the line of credit. The Company believes it has the ability, and it is the Company’s intention, to renew the line of credit at its maturity in 2007.
Operating activities provided cash of $9,164,000 in 2006. Net income of $1,656,000, depreciation and amortization of $5,963,000 and an increase in the minority interest of $1,314,000 were the primary reasons for the increase in operating cash flow. The Company’s trade accounts receivable increased to $4,248,000 at December 31, 2006 from $3,832,000 at December 31, 2005, primarily due to additional revenue from some of the Company’s retail sites which have a longer collection period than fee per use sites. This resulted in an increase in the number of days revenue (sales) outstanding (“DSO”) in accounts receivable to 81 days from 76 days as of December 31, 2006 compared to the prior year. We expect DSO to fluctuate in the future depending on timing of customer payments received and the mix of fee per use versus retail customers.
Investing activities used $4,746,000 of cash in 2006 primarily due to the acquisition of property and equipment of $5,146,000, which included upgrades to two Gamma Knife units, an option to purchase two proton beam units, and deposits on three Gamma Knife units and an IGRT system.
Financing activities used $1,764,000 of cash during 2006, primarily due to principal payments on long-term debt and capital leases of $6,549,000, distributions to minority owners of $798,000 and the payment of dividends of $954,000. This was partially offset by financing on the acquisition of property and equipment of $2,532,000, and borrowing on the Company’s line of credit with a bank in the amount of $4,000,000, which was used primarily for the Company’s investment in Still River and its option to purchase two proton beam systems.
The Company had negative working capital at December 31, 2006 of $541,000 compared to working capital of $2,423,000 at December 31, 2005 primarily due to borrowing $4,000,000 on its line of credit with a bank. Borrowing under the line of credit is considered a current liability because the line is renewable annually. The borrowed funds were used to invest in equipment and other non-current assets.
The Company primarily invests its cash in money market or similar funds and high quality short to long-term securities in order to minimize the potential for principal erosion. Cash is invested in these funds pending use in the Company’s operations. The Company believes its cash position is adequate to service the Company’s cash requirements in 2006.
The Company finances all of its Gamma Knife units, and anticipates that it will continue to do so with future contracts. During 2003 the Company’s primary lender, DVI, filed for Chapter 11 bankruptcy protection. The principal balance of notes held by DVI were transferred to a third party lender as successor servicer, and the Company continues to make payments on the outstanding note balances serviced by this third party lender. Since that time, the Company has secured financing for its projects from other lenders and anticipates that it will be able to secure financing on future projects from these or other lending sources, but there can be no assurance that financing will continue to be available on acceptable terms. The Company meets all debt covenants required under notes with its lenders, and expects that any covenants required by future lenders will be acceptable to the Company.

IMPACT OF INFLATION AND CHANGING PRICES
The Company does not believe that inflation has had a significant impact on operations because a substantial majority of the costs that it incurs under its customer contracts are fixed through the term of the contract.
CONTRACTUAL OBLIGATIONS, COMMITMENTS, CONTINGENT LIABILITIES AND OFF BALANCE SHEET ARRANGEMENTS
The following table presents, as of December 31, 2006, the Company’s significant fixed and determinable contractual obligations by payment date.

(1)   The Company has deposits toward the purchase of Gamma Knife Perfexion units, an IGRT system and two Clinatron 250 proton beam units, for which the total estimated purchase price is included above. For the two Clinatron 250 units specifically, the Company has a commitment to total deposits of $3,000,000 per machine until FDA approval is received, at which time the remaining balance is committed. Interim financing has been committed for $1,000,000 per machine towards these purchases. For the Perfexion and IGRT systems, financing commitments are in place, or are pending final site selection. For all equipment in this classification, term financing for these purchases will not be finalized until 2007 or later, and therefore an accurate determination of payments by period cannot be made as of December 31, 2006. For purposes of this table, these commitments are listed in the 1-3 year category.
Further discussion of the long-term debt commitment is included in Note 4, capital leases in Note 5, and operating leases in Note 10 of the consolidated financial statements.
The Company has no significant off-balance sheet arrangements.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders
American Shared Hospital Services
We have audited the accompanying consolidated balance sheets of American Shared Hospital Services as of December 31, 2006 and 2005, and the related consolidated statements of income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2006. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board of the United States of America. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purposed of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of American Shared Hospital Services at December 31, 2006 and 2005, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2006 in conformity with U.S. generally accepted accounting principles.
As discussed in Note 2 to the financial statements, effective January 1, 2006, the Company changed its method of accounting for share-based payment agreements to conform to Statement of Financial Accounting Standards No. 123(R), Share-Based Payment.

The Company (through American Shared Radiosurgery Services (“ASRS”)) and Elekta AB, the manufacturer of the Gamma Knife (through its wholly owned United States subsidiary GKV Investments, Inc. (“GKV”)), entered into an operating agreement and formed GK Financing, LLC (“GKF”). GKF is a non-exclusive provider of alternative financing services for Eletka Gamma Knife units in the United States and Brazil.
OR21, Inc., is a wholly-owned subsidiary of the Company that will provide the product “The Operating Room for the 21st Century®”, which is currently under development.
MedLeader.com, Inc., is a wholly-owned subsidiary of the Company that will provide continuing medical education online and through videos for doctors, nurses and other healthcare workers. This subsidiary is not operational at this time.
The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, OR21, Inc., MedLeader.com, Inc., ASRS and its majority-owned subsidiary, GK Financing, LLC.
All significant intercompany accounts and transactions have been eliminated in consolidation.
Note 2 — Accounting Policies
Use of estimates in the preparation of financial statements — In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and cash equivalents — The Company considers all liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Restricted cash is not considered a cash equivalent for purposes of the consolidated statements of cash flows.
Securities — The Company invests excess cash in short to long term fixed income marketable securities. It is the Company’s intent and ability to hold these securities until maturity and they are therefore regarded as held-to-maturity investments. As of December 31, 2006, the cost of

Note 2 — Accounting Policies (Continued)
these securities approximated fair market value, and they ranged in maturity up to approximately eighteen months. The value of those securities with maturity dates greater than one year are considered long-term securities and are classified accordingly on the balance sheet.
Restricted cash — Restricted cash represents the minimum cash that, by agreement, must be maintained in GKF to fund operations.
Business and credit risk — The Company maintains its cash balances, which exceed federally insured limits, in financial institutions. Additionally the Company’s securities are invested in short to long term fixed income securities that are not insured. The Company has not experienced any losses and believes it is not exposed to any significant credit risk on cash, cash equivalents and securities.
All of the Company’s revenue is provided by twenty-one customers. These customers constitute accounts receivable at December 31, 2006. The Company performs credit evaluations of its customers and generally does not require collateral. The Company has not experienced significant losses related to receivables from individual customers or groups of customers in any particular geographic area.
Accounts receivable and doubtful accounts — Accounts receivable are recorded at net realizable value. An allowance for doubtful accounts is estimated based on historical collections plus an allowance for probable losses. Receivables are considered past due based on contractual terms and are charged off in the period that they are deemed uncollectible. Recoveries of receivables previously charged off are recorded when received.
Accounting for majority-owned subsidiary — The Company accounts for GKF as a consolidated entity due to its 81% majority-equity interest.
Property and equipment — Property and equipment are stated at cost less accumulated depreciation. Depreciation is determined using the straight-line method over the estimated useful lives of the assets, which for medical and office equipment is generally 3 — 15 years. The Company capitalized interest of $53,000 and $17,000 in 2006 and 2005, respectively, as costs of medical equipment.
The Company leases Gamma Knife equipment to its customers under arrangements accounted for as operating leases. At December 31, 2006, the Company held equipment under operating lease contracts with customers with an original cost of $57,628,000 and accumulated depreciation of $29,493,000. At December 31, 2005, the Company held equipment under operating lease contracts with customers with an original cost of $55,348,000 and accumulated depreciation of $24,074,000.

Note 2 — Accounting Policies (Continued)
Revenue recognition — Revenue is recognized when services have been rendered and collectibility is reasonably assured. There are no guaranteed minimum payments. The Company’s contracts are typically for a ten year term and are classified as either fee per use or retail. Retail arrangements are further classified as either turn-key or net revenue sharing. Revenue from fee per use contracts is recorded on a gross basis as determined by each hospital’s contracted rate. Under turn-key arrangements, the Company receives payment from the hospital in the amount of its reimbursement from third party payors, and is responsible for paying all the operating costs of the Gamma Knife. Revenue is recorded on a gross basis and estimated based on historical experience and hospital contracts with third party payors. For net revenue sharing arrangements the Company receives a contracted percentage of the reimbursement received by the hospital less the operating expenses of the Gamma Knife. Revenue is recorded on a net basis and estimated based on historical experience. Any revenue estimates are reviewed periodically and adjusted as necessary. Revenue recognition is consistent with guidelines provided under EITF 99-19.
Income taxes — The Company accounts for income taxes in accordance with SFAS No 109, Accounting for Income Taxes. Under this method, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.
Earnings per share — Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the year. Diluted earnings per share reflect the potential dilution that could occur if common shares were issued pursuant to the exercise of options or warrants. The following table illustrates the computations of basic and diluted earnings per share for the years ended December 31, 2006, 2005 and 2004.

In 2006 options outstanding to purchase 6,500 shares of common stock at an exercise price of $6.45 per share were not included in the calculation of diluted earnings per share as the exercise price of the options was greater than the average market price of common stock during the year.
In 2005, options outstanding to purchase 76,000 shares of common stock at an exercise price of $6.16 — $6.45 per share were not included in the calculation of diluted earnings per share as the exercise price of the options was greater than the average market price of common stock during the year.
Stock-based compensation — On June 28, 2006, the Company’s shareholders approved the 2006 Stock Incentive Plan (the “2006 Plan”) under which 750,000 shares of the Company’s common stock are reserved for issuance of shares to officers of the Company, other key employees, non-employee directors, and advisors. The 2006 Plan serves as successor to the Company’s previous two stock-based employee compensation plans, the 1995 and 2001 Stock Option Plans. The share reserve under those two plans, including the shares of common stock subject to currently outstanding options under the plans, were transferred to the 2006 Plan, and no further grants or share issuances will be made under the 1995 Plan or 2001 Plans. Under the 2006 Plan, there are 2,000 restricted stock units granted, consisting of annual automatic grants to non-employee directors, and approximately 149,000 options granted, of which approximately 76,000 options are vested, as of December 31, 2006.

Note 2 — Accounting Policies (Continued)
Through 2005, the Company accounted for these plans using the intrinsic value method prescribed by APB Opinion No. 25, Accounting for Stock Issued to employees, and related Interpretations. No stock-based employee compensation cost was reflected in net income as all options granted under those plans had an exercise price greater than or equal to the market value of the underlying common stock on the date of grant.
On January 1, 2006, in accordance with Statement of Financial Accounting Standards No. 123(R), Share-Based Payments (“SFAS123(R)”), the Company began expensing the fair value of its stock options issued, using the modified prospective format. The Company’s stock-based awards to employees are calculated using the Black-Scholes valuation model. The Company’s stock-based awards have characteristics significantly different from those of traded options, and changes in the subjective input assumptions can materially affect the present value estimates. The fair value of the Company’s option grants issued during third quarter 2006 were estimated using weighted-average assumptions for expected life, volatility, dividend yield, forfeiture rate, and risk-free interest rate which are specific to each award as summarized in the table in Note 8. The estimated fair value of the Company’s options is amortized over the period during which the optionee is required to provide service in exchange for the award, usually the vesting period. Accordingly, stock-based compensation cost before income tax effect in the amount of approximately $39,000 is reflected in 2006 net income.
SFAS123(R) requires that excess tax benefits be reported as a financing cash inflow rather than as a reduction of taxes paid. There were approximately 17,000 options issued during 2006.
Pro forma information regarding net income and earnings per share was required by SFAS 123 for awards granted after December 31, 1995 through December 31, 2005, as if the Company had accounted for its stock-based awards to employees under the fair value method of SFAS 123. The fair value of the Company’s stock-based awards to employees was estimated using a Black-Scholes option pricing model.
The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS123(R) to stock-based employee compensation in 2005 and 2004. For pro forma purposes, the estimated fair value of the Company’s options is amortized over the options’ vesting period, which is generally from one to five years.

Fair value of financial instruments — The carrying amounts of financial instruments, including cash and cash equivalents, securities, restricted cash, accounts receivable, accounts payable, and other accrued liabilities approximated their fair value as of December 31, 2006 and 2005 because of the relatively short maturity of these instruments. The fair value of the Company’s various debt obligations, discounted at currently available interest rates was approximately $21,038,000 and $25,088,000 at December 31, 2006 and 2005, respectively.
Business segment information - The Company, which engages in the business of leasing equipment to health care providers, has one reportable segment, the Gamma Knife that non-invasively treats malignant and benign brain tumors, vascular malformations and trigeminal neuralgia.
Recent accounting pronouncements — In December 2003, the FASB issued FIN 46(R): Consolidation of Variable Interest Entities, an interpretation of ARB No. 51, which replaces FASB Interpretation No. 46, Consolidation of Variable Interest Entities (VIE). This Interpretation addresses consolidation by business enterprises of Variable Interest Entities. It defines a VIE as a corporation, partnership, trust, or any other legal structure used for the business purpose that either: a) the equity investment is not sufficient to allow the entity to finance its activities without additional financial support, b) the equity investors lack one or more of the following: 1. the ability to make decisions; 2. the obligation to absorb expected losses of the entity; or 3. the right to receive any returns of the entity, and, c) the equity investors have voting rights disproportionate to their economic interest, and the activities of the entity are

conducted on behalf of an investor with a disproportionately small voting interest. This interpretation requires that existing unconsolidated VIE’s be consolidated by their primary beneficiaries. The Company does not have any VIE entities and accordingly the implementation of the Interpretation did not result in an impact on its financial statements.
In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”) — an interpretation of FASB Statement No. 109. This Interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006 and, as such, the Company must adopt FIN 48 at January 1, 2007. The Company is currently evaluating the impact of adopting FIN 48 with respect to its net operating losses which total $9,498,000 at December 31, 2006, of which the tax effect was $3,289,000. The potential impact of adopting FIN 48 has not yet been determined by the Company. The impact, if any, would affect deferred tax assets and additional paid in capital.

At December 31, 2006, the Company had net operating loss carryforwards for federal income tax return purposes of approximately $9,498,000 which expire between 2012 and 2024, and net operating loss carryforwards for California franchise/income tax return purposes of approximately $1,026,000 which expire between 2011 and 2014. For state purposes, a substantial part of net operating loss carryforwards are subject to separate return limitations. The Company’s ability to utilize its net operating loss carryforwards and other deferred tax assets may be limited in the event of a 50% or more ownership change within any three-year period.

Note 8 — Shareholders’ Equity
2006 Stock Incentive Plan
The Company’s 2006 Stock Incentive Plan (the “2006 Plan”), provides for nonqualified stock options, qualified or “incentive stock options” and stock grants. Under the 2006 Plan, 750,000 common shares are reserved for awards to employees, non-employee members of the board of directors, and consultants and advisors to the Company. The Company had two previous stock option plans under which active options had been granted, the 1995 Stock Option Plan and the 2001 Stock Option Plan. Shares reserved under these two plans were transferred to the 2006 Plan upon its approval by the shareholders in June 2006, and those two plans are no longer active. Provisions of the 2006 Plan include an automatic annual grant to each non-employee director of options to purchase up to 2,000 shares on the date of the Company’s Annual Shareholder Meeting, at an exercise price equal to the market price of the Company’s common shares on that date, and an automatic annual grant of 500 restricted stock units of the Company’s common shares. Options and restricted stock units awarded under the automatic annual grant program for non-employee directors vest after one year. Other options may vest fully and immediately, or over periods of time as determined by the Plan Administrator, but no longer than seven years from the grant date. Options currently awarded under the 2006 Plan vest over a period of 5 years.
As of December 31, 2006, 2,000 restricted stock units have been granted and approximately 149,000 stock options are issued and outstanding under the 2006 Plan, of which approximately 133,000 shares were transferred from the previous plans. There have been no restricted stock units awarded outside the automatic grant program for non-employee directors.

At December 31, 2006 there was approximately $83,000 of unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the 2006 Plan. This cost is expected to be recognized over a period of approximately four years.
Shares and Options Issued to Officer
On August 15, 1995, the Company’s Chairman and Chief Executive Officer was granted a ten-year, immediately exercisable option to purchase 1,495,000 common shares for an exercise price of $.01 per share for which the Company recorded compensation expense of $2,414,000. These options were granted to the officer as final consideration for personal guarantees of credit facilities and for continued employment with the Company. All options granted under the plan were exercised prior to the termination of the plan according to its terms on August 15, 2005. The officer exercised 264,000 and 846,000 during 2005 and 2004. The exercise in 2005 resulted in a $445,000 increase in paid in capital and a $616,000 increase in deferred tax assets. The exercise in 2004 resulted in a $994,000 increase to additional paid in capital and a $1,540,000 increase in deferred tax assets.

At December 31, 2006 and 2005, 76,000 and 60,000 options, respectively, were vested and exercisable. Automatic option awards issued to non-employee directors vest one year after their issuance. The vesting period for all other options issued under the Company’s plans is determined by the Board of Directors at the time the options are issued. Discretionary options awarded during 2006 and 2005 vest over a five year period.
The Black-Scholes options valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, the Black-Scholes model requires the input of highly subjective assumptions including the expected stock price volatility. Because the Company’s stock-based awards to employees have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its stock-based awards to employees.
The fair value of the Company’s option grants under the 2006 Plan in 2006 and the 1995 and 2001 Plans in 2005 and 2004 was estimated assuming the following weighted-average assumptions:
                         
    2006     2005     2004  
Expected life (years)
    10.0       10.0       10.0

    5.0 - 8.5 %     0.0 %     0.0 %
Expected volatility
    25.0 - 72.5 %     25.0 %     37.0 %
Dividend yield
    3.0 %     3.1 %     3.0 %
Risk-free interest rate
