Abstract

The current research aims to investigate the power of financial distress prediction models while presenting a combination model, comparing the extracted model with the Merton model and the binary logistic regression model in predicting financial distress. In order to achieve the purpose of the research, the information of 168 distressed companies selected based on the specific criteria of distress and 168 healthy companies admitted to the Tehran Stock Exchange between 2006 and 2019 have been used. After reviewing past studies, 25 variables affecting financial distress, including 17 accounting variables, 4 market variables, and 4 macroeconomic variables, were identified, and by emphasizing the frequency and successful performance of these ratios in past studies and performing statistical tests, the final indicators were selected. To determine the dependent variable, Merton's model was used, and finally, by applying the logit model and determining the relationship between the independent variables and the dependent variable, a composite model was extracted. The research results showed that adding economic and stock market variables to financial variables does not increase the ability to predict financial distress and the combined model has better explanatory power than the Merton model and binary logistic regression. In the present research, to predict financial distress, all three categories of accounting, economic and stock market variables are considered together, and the emphasis is not only on accounting variables, and the combined model is compared with the accounting and market model.

Abstract

The photonic device market has a need for low‐cost, high‐resolution periodic patterning that scales with product maturity to large substrate sizes. Eulitha's DTL (Displacement Talbot Lithography) technology was limited to only a single exposure field per substrate on preexisting platforms which can fully pattern 100 and 150mm substrates. The new 'PhableS' is Eulitha's step‐and‐repeat solution to bring all the advantages of the DTL patterning to larger substrates. The PhableS tool builds on Eulitha's patented displacement Talbot lithography technology to open the way for customers to fully scale to high volume production. This tool retains the strong technical performance; including 60nm half pitch resolution (DUV version), 140x140mm2 single shot exposure field, large depth of focus (hundreds of microns), high throughput (+40wph), non‐contact, mask‐based patterning. Automated wafer and mask handling support industry expected repeatability and defect‐free patterning. [ABSTRACT FROM AUTHOR]
