Financial Instruments and Risk Management [Abstract]
Financial Instruments and Risk Management	Note 13 - Financial Instruments and Risk Management A. Concentration of credit risk Financial instruments that may subject the Company to significant concentrations of credit risk consist mainly of cash and cash equivalents and deposits in respect of employee severance benefits. Cash, cash equivalents and short-term deposits are maintained with major financial institutions in Israel. Deposits in respect of employee severance benefits are maintained with major insurance companies and financial institutions in Israel. B. Concentrations of business risk The Company uses materials required for our research and development activities that are currently available from a limited number of sources. The Company believes that it will not experience delays in the supply of critical components in the future. If the Company experiences such delays and there is an insufficient inventory of critical components at that time, the Company's operations and financial results would be adversely affected.
