Does OPI Affect Induced Effects?

Though I cannot find it now, I thought I had read somewhere that other property income does not affect the induced effect of the model. Is that correct? The reason I am asking is because I am trying to model the impact of a non-profit museum that sets aside a portion of its receipts (which I am using as the output shock) for future exhibit development and a disaster relief fund. Since these funds are not expended to create output in an average year, I am thinking about modifying the industry data and allocating the amount of these set asides to OPI in sector 406. Is this a reasonable approach?
