What are your best practices for fixed asset management?

The IRS recently issued Notice 2015-82 that is allowing companies without AFS to expense tangible personal property items up to $2500, which is an increase from the original $500. Companies with AFS have a limit of $5,000 (which it has had for a couple of years now). The AICPA issued a letter to the IRS urging the increase stating the lesser "threshold was too low to do much to reduce the burden of complying with the complex capitalization rules." The IRS stated that it will not raise the issue of higher amounts during an audit for tax years beginning after December 31, 2011 and ending before January 1, 2016. Basically, companies could have got away with using a higher capitalization point during those years. Do you go back and expense your capitalized items in 2015, since you won't be penalized for doing so? What are some of your best practices for fixed asset management? How will your best practices change in light of the new IRS rules? Are the majority of the companies represented within this community have AFS?
