Why they said they were late

As previously disclosed by Apartment Investment and Management Company and Aimco OP L.P. (collectively, “Aimco” or the “Company”), on December 15, 2020, the Company completed the previously announced separation of its businesses (the “Separation”), creating two, separate and distinct, companies, Aimco and Apartment Income REIT Corp. The Company could not complete the filing of its quarterly report on Form 10-Q for the for the period ended June 30, 2021 without unreasonable effort or expense, due to the complexities and time spent implementing a new accounting system as a result of the Separation.

The Company intends to file its 2021 Form 10-Q no later than the fifth calendar day after its prescribed due date. 2

As previously disclosed by Apartment Investment and Management Company and Aimco OP L.P. (collectively, “Aimco” or the “Company”), on December 15, 2020, the Company completed the previously announced separation of its businesses (the “Separation”), creating two, separate and distinct, companies, Aimco and Apartment Income REIT Corp. The Company could not complete the filing of its quarterly report on Form 10-Q for the three months ended March 31, 2021 without unreasonable effort or expense, due to the complexities of implementing a new financial reporting and accounting system as a result of the Separation. Management of the Company has determined that it requires additional time to complete its review of the Company’s financial statements and other disclosures in the Form 10-Q. The Company intends to file its March 31, 2021 Form 10-Q no later than the first business day following five calendar days after its prescribed due date. 2

2021-03-01filed late (10-K)complex accounting SEC →

As previously disclosed by Apartment Investment and Management Company and Aimco OP L.P. (collectively, “Aimco” or the “Company”), on December 15, 2020, the Company completed the previously announced separation of its businesses (the “Separation”), creating two, separate and distinct, companies, Aimco and Apartment Income REIT Corp. The Annual Report on Form 10-K for the year ended December 31, 2020 will be the Company’s first annual report subsequent to the Separation. Due to the timing of the Separation, the complexity associated with preparing the Company’s financial statements predominately on a carve out basis in accordance with US GAAP and the complexity of accounting for certain assets and liabilities obtained in the Separation, management of the Company has determined that it requires additional time to complete its review of the Company’s financial statements and other disclosures in the Form 10-K. The Company is therefore unable to file its 2020 Annual Report on Form 10-K within the prescribed time without unreasonable effort or expense. The Company intends to file its 2020 Form 10-K no later than the fifteenth calendar day after its prescribed due date. 2

About this score

reportingrisk.com scores every active US filer on three things a company tells the SEC about itself: late-filing notices on Form NT, 8-K item 4.02 (past accounts declared unreliable) and 4.01 (auditor changes). 1,012 are flagged today.

Every score is frozen and checked twelve months later. Across 91,452 of them, a company scoring 4 or more ended that year delisted, bankrupt, restated or silent 17.2% of the time, against 4.0% for a clean record. Scores before 2026-09-27 were reconstructed from the filing history as it stood at each date, so the record is a backtest rather than years of live calls.
