capital object

Registered capital: { current, history }. current carries amount, currency and kind (STAMMKAPITAL, GRUNDKAPITAL, HAFTSUMME, GENEHMIGTES_KAPITAL, BEDINGTES_KAPITAL, VARIABLES_KAPITAL — open enum); each history entry has value, effective_from and effective_to (null = still in force). change_amount on a history entry is unsigned and does not always equal the difference between two consecutive amounts, so derive increases and decreases from the amounts. Partnerships and other entities without registered capital return current: null and an empty history.

contact_data object

website, phone_number and email when available.

industry_classification object

Industry codes per WZ2008 and WZ2025 with labels.

features=financial_kpi

financial_kpi array<object>

Per fiscal year: revenue, employees, active_total (balance-sheet total), net_income, material_expenses, personnel_expenses. Every year names the source of its figures in _provenance: statement_type (Jahresabschluss = annual accounts, Bilanz = balance sheet only, Konzernabschluss = consolidated accounts; null for market data), period_start and period_end of the fiscal year, plus exempt_subsidiary and parent_organization ({ entity_id, name }). With exempt_subsidiary: true the company published the consolidated accounts of parent_organization instead of accounts of its own, so that year's figures cover the whole group.

features=balance_sheet_accounts

balance_sheet_accounts array<object>

Per fiscal year: hierarchical balance-sheet line items from the published statement, with _provenance naming the source of the figures (fields as in financial_kpi). For energy utilities, Max accounts also receive activity_statements through the API: the balance sheets of the activity statements (section 6b EnWG), one per regulated activity such as electricity or gas distribution; together they do not add up to the company's balance sheet.

features=profit_and_loss_account

profit_and_loss_account array<object>

Per fiscal year: hierarchical profit-and-loss line items, with _provenance naming the source of the figures (fields as in financial_kpi).

features=related_persons

related_persons object

Authorized representatives: { current: [...], past: [...] } — managing directors, board members, signatories. Each person carries organization_representation_scheme and role_representation_scheme (current scheme + history).

features=shareholders

shareholders object

Shareholders: { total_capital, entries: [...], history: { current_as_of, past: [...] } }.

ubos object

Ultimate beneficial owners: { beneficial_owners, unresolved_beneficial_owners, coverage } as recorded in the transparency register.

Anhang

1. Allgemeine Angaben:

Der Jahresabschluss wurde nach den Vorschriften des Dritten Buches des HGB (§ 242 ff HGB) und den ergänzenden Bestimmungen für Kapitalgesellschaften (§ 264 ff HGB) aufgestellt.

Die Gesellschaft ist eine kleine Kapitalgesellschaft im Sinne des § 267 Absatz 1 HGB.
Im Rahmen der Offenlegung des Jahresabschlusses gemäß § 325 HGB wurden die Erleichterungsvorschriften für kleine Gesellschaften gemäß §§ 326, 288, 274a HGB in Anspruch genommen.

2. Bilanzierungs- und Bewertungsgrundsätze:

Die Bewertung wurde entsprechend § 252 Abs. 1 Nr. 2 HGB unter der Annahme der Fortführung der Unternehmenstätigkeit vorgenommen.

Das Sachanlagevermögen wurde zu Anschaffungs- oder Herstellungskosten, vermindert um planmäßige Abschreibungen, angesetzt. Die Nutzungsdauer der einzelnen Anlagegegenstände wurde auf der Grundlage der steuerlichen AfA-Tabellen bestimmt. Bei der Umstellung auf die Vorschriften des BilMoG wurden die niedrigeren Wertansätze beibehalten (Art. 67 Abs. 4 EGHGB).

Es wurde eine gesonderte Steuerbilanz erstellt.

Die Finanzanlagen wurden grundsätzlich zu Anschaffungskosten, Ausleihungen zum Nennwert angesetzt.

Die Vorräte (Roh-, Hilfs- und Betriebsstoffe) wurden durch Bestandsaufnahme ermittelt und mit den Anschaffungskosten (§ 255 Absatz 1 HGB), halbfertige Arbeiten mit den Herstellungskosten (§ 255 Absatz 2 HGB) bewertet.

Forderungen und Wertpapiere wurden mit dem Nennbetrag angesetzt. Ausfall- und Kreditrisiken wurden durch angemessene Wertberichtigungen berücksichtigt.

Die sonstigen Vermögensgegenstände wurden zum Nennbetrag, flüssige Mittel zu Nominalwerten angesetzt.

Rückstellungen für ungewisse Verbindlichkeiten wurden nach üblicher kaufmännischer Schätzung gebildet. Dabei wurden alle erkennbaren Risiken berücksichtigt.

Verbindlichkeiten wurden zum Rückzahlungsbetrag angesetzt.

3. Verbindlichkeiten mit einer Restlaufzeit von über 5 Jahren:

Verbindlichkeiten mit einer Restlaufzeit von über fünf Jahren bestehen nicht.

4. Haftungsverhältnisse:

Am Abschlussstichtag bestanden keine aus der Bilanz nicht ersichtlichen Haftungsverhältnisse gemäß §§ 251, 268 Absatz 7 HGB.

5. Geschäftsführer/in:

Während des abgelaufenen Geschäftsjahres wurden die Geschäfte durch Herbert
Mayer geführt.

Inzwischen ist Frau Susanne Mayer zur Geschäftsführerin bestellt.
