      <ExplanationTxt>ATC currently uses Corptax as its income tax compliance provider. Unfortunately, due to technology constraints, our current e-file software provider, Corptax, does not have forms or submission technology available to file such form electronically. ATC is a Wisconsin based electric transmission utility, which owns and operates much of the high-voltage electric transmission grid in Wisconsin and Michigan. ATC is federally regulated by NERC / FERC to protect and operate critical infrastructure. As such, ATC has intense regulatory compliance obligations and review processes associated with using any new software systems or technology. These regulatory practices include supply chain and security reviews of suppliers. These practices help ensure the security and integrity of critical infrastructure to prevent cyber-attacks on the public's electric transmission grid as well as making sure the software's functionality meets all of ATC's specifications. Therefore, we are unable to quickly choose another e-file software provider and use them without incurring great cost, administrative difficulty, and time commitment. We even went as far as exploring having our fiduciary/trustee electronically file on our behalf which they were unable to do. Under our facts and circumstances then it would've created a great undue burden and hardship for the company to file the 990-T electronically. Coincidentally to all of this, ATC recently decided to change its income tax compliance provider from Corptax to OneSource in May of 2022. However, even though we started the process to switch from Corptax to OneSource four months ago, OneSource is still not fully up and running yet, and will take time to implement. However, we recently were able to set up the express version of the software for the sole purpose of gaining the ability to electronically file Forms 990 and 990-T. We are now filing these returns electronically, which is as soon as was reasonably possible.</ExplanationTxt>
