Lobbying and contracts

$20.0K · — in 12 mo

What Atara Biotherapeutics, Inc. reported spending on lobbying next to the federal contracts it was awarded, by year.Lobbying: each report counts once. If a report was amended, only the newest version counts. Totals use the company's own report when it files one (it includes payments to hired firms); otherwise the hired firms' reported income. Registrations and reports with no amount are not counted. A firm that hands part of its work to another firm may report the same money as that other firm does; the filings do not allow us to tell. Contracts: each award is counted once, for the company that received it (or its listed parent when only the parent is matched), in the year of its first obligation. The amount is the total obligated to date, so a later increase is counted in the year the award began. Only awards of $1 million or more are collected. Agencies: the offices named on lobbying reports and the awarding agencies of contracts are matched to one department name (the Army, Navy and Air Force count as the Department of Defense; NIH, FDA and CMS as Health and Human Services). An agency is listed under both when the company lobbied it and was awarded a contract by it in the same period. Offices outside this list, and Congress, are not counted as agencies.
