Will leasing lose its luster: an analysis of lease reporting under FAS 13

When standards for financial reporting are amended, potential for change in the appearance of financial position for companies reporting under those standards arises. Currently standards set forth by the Financial Accounting Standards Board (FASB) allow for two methods of reporting lease obligations on the financial statements. The first of these methods is the operating method, which allows lease payments to be expensed within the period they are incurred and only a decrease in cash or an increase in an account payable is recognized on the balance sheet. The second method is the capital method, which requires the present value of the future lease payments to be recognized on the balance sheet as an asset and a corresponding liability. Both are reduced annually through depreciation and lease payments respectively. The FASB has recently proposed discontinuing the operating method of reporting a lease obligation and allowing only for the capital method to be used. The objective of this study is to examine some of the changes in appearance of financial position that might be brought on by this potential change in reporting standards. The airline industry has been selected to illustrate the effects of capitalizing future operating lease payments on the balance sheet. These future payments under operating leases for companies within the industry are capitalized using two different methods of depreciation. The companies are then ranked in order of proximity to an industry average for eight well known financial ratios. The rankings for each treatment on a given ratio are compared and differences between the expensed ranking and each capitalized ranking are measured and discussed

Ammonia Emissions from U.S. Poultry Houses: Part III—Broiler Houses

A multi-state, multi-disciplinary project is developing a comprehensive database of ammonia emissions from US poultry facilities. The influence of common management strategies and practical means of reducing ammonia (NH3) emissions are under study. The measurement of ammonia emissions under cold weather conditions from 11 broiler houses in Kentucky and Pennsylvania is described in this paper. Ammonia level was determined using electrochemical sensors; ventilation rate was estimated by monitoring runtime of the ventilation fans whose airflow rates were determined with a portable anemometer array, also known as the Fan Assessment Numeration System (FANS). Ammonia emission rates ranged from 0 to 0.92 g NH3 bird-1 d-1 or, expressed in terms of 500 kg animal units (AU), 0 to 607 g NH3 AU-1 d-1. Bird age ranged from 1 to 23 days. There was high variability for emission rates among the houses, even for houses on the same farm. Day to day variability (consecutive days) was less than house-to-house variability for the same time period. A better interpretation of the wide range of emissions rates can be made once characteristics of the litter, flock, and house management can be incorporated into data analysis

Ammonia Emissions from USA Broiler Chicken Barns Managed with New Bedding, Built-up Litter, or Acid-Treated Litter

Poultry producers in the United States have attempted to maintain barn aerial ammonia (NH3) levels below 25 ppm to improve air quality, and more recently to decrease aerial emissions to the atmosphere. Our objective was to investigate the influence of litter management strategies on NH3 emissions from commercial broiler barns employing new bedding, acid-treated built-up litter (sodium bisulphate), or untreated built-up litter (normal practice). Nearly 400 barn-days of NH3 emissions data were collected from 12 broiler barns on four farms monitored in 48-hour episodes over one year. On each study farm, the barns were paired for repetition of conditions. Emission was calculated as the product of gas concentration of the exhaust air and barn ventilation rate. Use of new bedding for every flock led to consistently lower NH3 emission (averaging 0.35 g NH3/(bird d)) at day 21 of the 42-day flock grow-outs, followed by flocks raised on the annual cleanout with new bedding (0.52 g NH3/(bird d)). Built-up litter without any treatment had the highest emission (0.73 g NH3/(bird d)), followed by the built-up litter with acid treatment (0.63 g NH3/(bird d)). One study site was managed with two barns using litter treatment and two identical barns with untreated, built-up litter for a side-by-side comparison of results under field conditions. Ammonia emissions from treated built-up litter barns were similar to those from untreated built-up litter barns, however, the temporal pattern of emissions provided evidence that ammonia held in the acid-treated litter at the beginning of the flock was released during the latter period of the flock cycle

Ammonia Emissions from U.S. Laying Hen Houses in Iowa and Pennsylvania

Ammonia (NH3) emission rates (ER) of ten commercial layer houses (six high-rise or HR houses and four manure- belt or MB houses) with different manure handling or dietary schemes were monitored for one year in Iowa (IA) and Pennsylvania (PA). Gaseous (NH3 and CO2) concentrations of incoming and exhaust air streams were measured using custom-designed portable monitoring units that shared similar performance to EPA-approved measurement apparatus. Building ventilation rates were determined by calibrated CO2 mass balance using the latest metabolic rate data for modern laying hens. The field monitoring involved a total of 386 and 164 house-day measurements or 18,528 and 7,872 30-min emission data points for the HR houses and the MB houses, respectively. The ER showed considerable diurnal and seasonal variations. The annual mean ERs (g NH3 hen-1 d-1) and standard errors were 0.90 ±0.027 for IA-HR houses with standard diet, 0.81 ±0.02 for IA-HR houses with a nutritionally balanced 1% lower crude protein diet, 0.83 ±0.070 for PA-HR houses with standard diet, 0.054 ±0.0035 for IA-MB houses with daily manure removal, and 0.094 ±0.006 for PA-MB houses with twice a week manure removal. Mass balance of nitrogen (N) intake and output performed for IA-HR houses revealed a total N intake recovery of 94% to 101%, further verifying the certainty of the NH3 ER measurements. Results of the study contribute to the U.S. national inventory on NH3 emissions from animal feeding operations, particularly laying hen facilities as affected by housing type, manure handling scheme, crude protein content of the diet, and geographical location

Measuring gas emissions from livestock buildings: A review on uncertainty analysis and error sources

Measuring gaseous and particulate emissions from livestock houses has been the subject of intensive research over the past two decades. Currently, there is general agreement regarding appropriate methods to measure emissions from mechanically ventilated buildings. However, measuring emissions from naturally ventilated buildings remains an elusive target primarily because there is no reference method for measuring building ventilation rate. Ventilation rates and thus building emissions estimates for naturally ventilated buildings are likely to contain greater errors compared with those from mechanically ventilated buildings. This work reviews the origin and magnitude of errors associated with emissions from naturally ventilated buildings as compared to those typically found in mechanical ventilation. Firstly, some general concepts of error analysis are detailed. Then, typical errors found in the literature for each measurement technique are reviewed, and potential sources of relevant systematic and random errors are identified. The emission standard uncertainty in mechanical ventilation is at best 10% or more of the measured value, whereas in natural ventilation it may be considerably higher and there may also be significant unquantifiable biases. A reference method is necessary to obtain accurate emissions estimates, and for naturally ventilated structures this suggests the need for a new means of ventilation measurement. The results obtained from the analysis of information in this review will be helpful to establish research priorities, and to optimize research efforts in terms of quality of emission measurements.
