Every line of code is a liability, in the accounting sense of the word. That is, it's what makes the asset (software) exist.
The balance sheet is always equal, so you always have as much liability as asset in amount. Despite the negative connotation of the word, some liabilities are good (earnings[1] is the best, equity and long term debt with low interest rate are nice too), but some are bad.
And it's the same for code, spitting more code to do the same thing is akin to emitting too many shares, having brittle code that needs constant intervention to keep working is akin to high interest debt.
[1] yes, your company's earning belong to the right side of its balance sheet.
