NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Income Recognition Third-Party Construction Services Stock-Based Employee Compensation method  which approximates the effective interest method. Leasehold improvements and equipment are depreciated on  the straight-line method over the shorter of the expected useful lives or the lease terms which range from 3 to 10 years.  Accumulated depreciation and amortization for such assets totaled $22.7 million in 2004 and $19.3 million in 2003. Our rental and other property income is recorded when due from residents and is recognized monthly as it is earned.  Other property income consists primarily of utility rebillings  and administrative  application and other transactional  fees charged to our residents. Our apartment homes are rented to residents on lease terms generally ranging from  6 to 13 months  with monthly payments due in advance. Interest  fee and asset management and all other sources of  income are recognized as earned. Two of our properties are subject to rent control or rent stabilization. Operations of  apartment properties acquired are recorded from the date of acquisition in accordance with the purchase method of  accounting. In management’s opinion  due to the number of residents  the type and diversity of submarkets in which  the properties operate  and the collection terms  there is no significant concentration of credit risk. Our construction division performs services for our internally developed communities  as well as provides  construction management and general contracting services for third-party owners of multifamily  commercial and  retail properties. Income from these third-party projects is recognized on a percentage-of-completion basis. For  projects where our fee is based on a fixed price  any cost overruns  as compared to the original budget  incurred  during construction will reduce the fee generated on those projects. For any project where cost overruns are expected  to be in excess of the fee generated on the project  we will recognize the total projected loss in the period in which the  loss is first estimated. See Note 7 for further discussion of our third-party construction services. Prior to 2003  we accounted for option grants under the intrinsic method set forth in Accounting Principles Board  (“APB”) Opinion No. 25  “Accounting for Stock Issued to Employees”  and related Interpretations. Beginning 2003  we  adopted Statement of Financial Accounting Standards (“SFAS”) No. 148  “Accounting for Stock-Based Compensation  – Transition and Disclosure”  an amendment of SFAS No. 123  “Accounting for Stock-Based Compensation”. As a  result of our adoption of the prospective method set forth in SFAS No. 148  we recognize stock-based employee  compensation when new options are awarded. We recorded compensation expense totaling $0.6 million and $0.2  million during the years ended 2004 and 2003  respectively  associated with awards accounted for under the fair value  method. Additionally  we began recognizing compensation expense on shares purchased under our Employee Share  Purchase Plan (“ESPP”) for the difference in the price paid by our employees and the fair market value of our shares  at the date of purchase. We expensed $0.2 million related to ESPP purchases during 2004. The fair value of each option granted is estimated on the date of grant utilizing the Black-Scholes option pricing model  with the following assumptions used for grants in 2004  2003 and 2002 respectively: risk-free interest rates of 4.2%   4.0% and 5.0% to 5.2%; expected life of ten years; dividend yield of 5.9%  8.1% and 6.9% to 7.0%; and expected share  volatility of 18.0%  18.3% and 18.1%. The weighted average fair value of options granted in 2004  2003 and 2002 was  $3.83  $1.38 and $2.85 per share  respectively. 76 camden transforming
